NEW QUESTION # 32
Which protocol would be used to bundle multiple Ethernet ports into a virtual link with an aggregated bandwidth?

• A. ERP
• B. RSTP
• C. LACP
• D. VRRP

Answer: C

Explanation:
Explanation
The protocol that would be used to bundle multiple Ethernet ports into a virtual link with an aggregated bandwidth is LACP, which stands for Link Aggregation Control Protocol. LACP is a protocol that allows two or more devices to negotiate the formation of a link aggregation group (LAG), also known as an EtherChannel or a port channel. A LAG combines multiple physical links into one logical link that provides increased bandwidth, load balancing, and redundancy. LACP is defined in IEEE 802.3ad and 802.1AX standards12.

NEW QUESTION # 33
Which two label actions are performed by a P router? (Choose two.)

• A. php
• B. drop
• C. swap
• D. push

Answer: A,C

Explanation:
Explanation
A P router is a provider router that is part of the service provider's core network in an MPLS environment. A P router does not have any customer routes or VPN information, but only has information about how to reach other P routers and PE routers in the same MPLS domain. A P router performs label switching, which means that it forwards labeled packets based on their top label in the label stack. A P router can perform two possible label actions:
Swap: The P router replaces the incoming label with a new label that corresponds to the next hop along the label-switched path (LSP). The new label is determined by looking up the label forwarding information base (LFIB) based on the incoming label and interface.
PHP: The P router removes the top label from the packet at the penultimate hop before reaching the egress PE router. This is done to avoid an extra lookup on the egress PE router, which can forward the packet based on its IP header or another label in the stack.
A P router does not perform push or drop actions on labels. A push action means adding one or more labels to the packet, which is done by an ingress PE router when initiating an LSP. A drop action means discarding a packet, which is done by any router when there is no matching entry in its LFIB or routing table.

NEW QUESTION # 34
Which conceptual table created by routing protocols is used when processing an IP packet?

• A. label information base
• B. management information base
• C. traffic engineering data base
• D. forwarding information base

Answer: D

Explanation:
Explanation
The conceptual table created by routing protocols that is used when processing an IP packet is the forwarding information base (FIB). The FIB is a table that contains the bestroutes to reach each destination network prefix, along with the outgoing interface and the next-hop address for each route. The FIB is derived from the routing information base (RIB), which is a table that contains all the routes learned from different routing protocols and sources. The FIB is used by the router to make fast forwarding decisions for each incoming packet, based on its destination address12.

NEW QUESTION # 35
In an Ethernet frame carrying a VLAN tag, where does the VLAN tag appear?

• A. after the type field
• B. before the length field
• C. before the type field
• D. after the length field

Answer: C

Explanation:
Explanation
In an Ethernet frame carrying a VLAN tag, the VLAN tag appears before the type field. A VLAN tag is a
4-byte field that is inserted into an Ethernet frame to indicate the VLAN membership and priority of the frame.
The VLAN tag consists of two subfields: the tag protocol identifier (TPID) and the tag control information (TCI). The TPID subfield is a 16-bit field that identifies the frame as an IEEE 802.1Q-tagged frame, with a value of 0x8100. The TCI subfield is a 16-bit field that contains the priority code point (PCP), the drop eligible indicator (DEI), and the VLAN identifier (VID). The VLAN tag appears between the source MAC address and the type fields of the original frame, shifting the type field by four bytes. The type field indicates the type of the payload, such as IP or ARP .

NEW QUESTION # 36
What are two roles of the DHCP protocol in a network? (Choose two.)

• A. It is used by hosts to obtain the IP address and other parameters from the DHCP server.
• B. It provides information about the number of hops between the source and the destination.
• C. It is used to inform hosts about the default gateway.
• D. It provides the authorization function to the network.

Answer: A,C

Explanation:
Explanation
Two roles of the DHCP protocol in a network are:
It is used by hosts to obtain the IP address and other parameters from the DHCP server. DHCP stands for Dynamic Host Configuration Protocol, which is a protocol that provides automatic and centralized management of IP addresses and other network configuration parameters for devices connected to a network. A host that needs an IP address can send a request to a DHCP server, which will assign an available IP address from a pool and lease it to the host for a certain period of time34.
It is used to inform hosts about the default gateway. The default gateway is the IP address of the router that connects the host to other networks. The default gateway is one of the parameters that can be delivered by the DHCP server to the host, along with other parameters such as subnet mask, DNS server, domain name, etc. The host can use the default gateway to send packets to destinations outside of its local network34.

NEW QUESTION # 37
Which two statements are true regarding the LSP? (Choose two.)

• A. The LSP refers to a sequence of routers that forward the MPLS packet based on labels.
• B. The LSP refers to a specific label assigned to a packet by the LSR for a destination.
• C. The LSP refers to a sequence of routers that add, remove, or change label values based on the destination MAC address.
• D. The LSP refers to a sequence of routers that add. remove, or change label values along the path.

Answer: A,D

Explanation:
Explanation
Two statements that are true regarding the LSP are:
The LSP refers to a sequence of routers that forward the MPLS packet based on labels. An LSP is a Label Switched Path, which is a path through an MPLS network that is established by signaling protocols such as LDP or RSVP-TE. An LSP consists of a sequence of routers (called Label Switching Routers or LSRs) that forward packets based on labels rather than IP addresses. Labels are short fixed-length identifiers that are attached to packets at the ingress router and removed at the egress router. Labels can be swapped or popped at intermediate routers according to their label forwarding tables78.
The LSP refers to a sequence of routers that add, remove, or change label values along the path. As mentioned above, an LSP consists of a sequence of routers that forward packets based on labels. Along the path, different routers may perform different operations on the labels depending on their role and configuration. The ingress router adds one or more labels to the packet before sending it into the MPLS network. The egress router removes all labels from the packet before sending it out of the MPLS network. The intermediate routers may swap one label with another label according to their label forwarding tables. This process is called label switching78.

NEW QUESTION # 38
For IP destinations not found in the IS-IS Level 1 database, the Level 1 router must forward packets to the nearest Level 1-Level 2 router with which set?

• A. status bit
• B. attach bit
• C. overload bit
• D. options bit

Answer: B

Explanation:
Explanation
For IP destinations not found in the IS-IS Level 1 database, the Level 1 router must forward packets to the nearest Level 1-Level 2 router with the attach bit set. The attach bit is a flag in the IS-IS Level 1 LSP that indicates that the router is also a Level 2 router and can reach destinations outside the Level 1 area. The Level
1 router will install a default route pointing to the nearest Level 1-Level 2 router with the attach bit set. This way, the Level 1 router can forward packets to other areas without having to maintain a full Level 2 database.

NEW QUESTION # 39
IPv6 link-local addresses are designed to be used in which three situations? (Choose three.)

• A. for neighbor discovery
• B. addressing on a single link for purposes such as auto-address configuration
• C. for local IP communication on the IPv6 capable routers
• D. when routers are not present
• E. by routers to forward packets with link-local source addresses to other links

Answer: A,B,C

Explanation:
Explanation
IPv6 link-local addresses are designed to be used in three situations: for neighbor discovery, for local IP communication on the IPv6 capable routers, and for addressing on a single link for purposes such as auto-address configuration. Neighbor discovery is a protocol that allows IPv6 nodes to discover each other and learn their link-layer addresses on a local network. Neighbor discovery uses link-local addresses to send and receive messages such as router advertisements, router solicitations, neighbor advertisements, and neighbor solicitations34. Local IP communication on the IPv6 capable routers refers to the ability of routers to exchange routing information or management traffic using their link-local addresses as source and destination addresses. This reduces the need for global unicast addresses on router interfaces that are not reachable from outside the local network35. Addressing on a single link for purposes such as auto-address configuration refers to the use of link-local addresses to enable IPv6 nodes to obtain an address without manual configuration or a DHCP server. Link-local addresses can be automatically derived from the interface identifier in the modified EUI-64 format or randomly generated. Link-local addresses can also be used to test the connectivity of a link before obtaining a global unicast address36.

NEW QUESTION # 40
In OSPFv2, which route characteristic is used to determine the best path?

• A. jitter
• B. cost
• C. delay
• D. packet loss

Answer: B

Explanation:
Explanation
In OSPFv2, the route characteristic that is used to determine the best path is the cost. The cost is a metric that represents the link bandwidth, delay, reliability, or other factors. The cost is inversely proportional to the bandwidth, meaning that a higher bandwidth link has a lower cost. The cost of a route is calculated by adding the costs of all links along the path. OSPFv2 uses the following formula to calculate the cost of an interface:
Cost = Reference bandwidth / Interface bandwidth in bps
The reference bandwidth is a constant value that can be configured by the network administrator. By default, it is 100 Mbps. The interface bandwidth is the actual bandwidth of the interface in bits per second. For example, if an interface has a bandwidth of 10 Mbps, its cost would be 100 Mbps / 10 Mbps = 101415.
OSPFv2 does not use jitter, packet loss, or delay as route characteristics to determine the best path. Jitter is the variation in latency or delay between packets. Packet loss is the percentage of packets that are dropped or corrupted during transmission. Delay is the time it takes for a packet to travel from source to destination. These characteristics are not part of the OSPFv2 protocol and are not advertised in OSPFv2 LSAs1617.

NEW QUESTION # 43
Which route type is restricted in an OSPF stub area?

• A. Type 1
• B. Type 5
• C. Type 3
• D. Type 2

Answer: B

Explanation:
Explanation
The route type that is restricted in an OSPF stub area is type 5. Type 5 LSAs are external LSAs that are generated by ASBRs to advertise routes from other routing domains or protocols into OSPF. Type 5 LSAs are flooded throughout the OSPF domain by default, except in stub areas. Stub areas are special OSPF areas that block type 5 LSAs from entering the area in order to reduce the size of the LSDB and the routing table. Stub areas only receive information about intra-area routes (type 1 and 2 LSAs), inter-area routes (type 3 LSAs), and a default route (type 3 LSA with destination 0.0.0.0/0) from the ABRs910.

NEW QUESTION # 44
What is an important difference between OSPF and IS-IS?

• A. OSPF is a link state protocol, while IS-IS is a distance vector protocol.
• B. OSPF runs directly on IP, while IS-IS runs directly on Ethernet.
• C. OSPF runs directly on Ethernet, while IS-IS runs directly on IP.
• D. OSPF is a distance vector protocol, while IS-IS is a link state protocol.

Answer: B

Explanation:
Explanation
OSPF runs directly on IP, while IS-IS runs directly on Ethernet. This means that OSPF uses IP addresses to identify routers and links, while IS-IS uses MAC addresses or other link-layer identifiers. OSPF also requires an IP header for each packet, while IS-IS does not. Both OSPF and IS-IS are link state protocols, which means that they flood information about the network topology to all routers in the same area or domain.

NEW QUESTION # 45
In a company network, a host sends an Ethernet frame destined to the address FF:FF:FF:FF:FF:FF.
What will an Ethernet switch do with this frame?

• A. It will forward the frame to only one port.
• B. It will forward the frame to all ports.
• C. It will drop it.
• D. It will send the frame only to management port.

Answer: B

Explanation:
Explanation
An Ethernet switch will forward the frame to all ports when the destination address is FF:FF:FF:FF:FF:FF.
This is because this address is the broadcast MAC address, which means that the frame is intended for all devices on the same LAN segment. The switch does not need to look up its MAC address table to find a matching entry for this address, but simply floods the frame out of all ports except the one where it received the frame. This way, the frame reaches every device on the LAN segment, regardless of their MAC addresses. References: Ethernet - Wireshark, Broadcast MAC Address - omnisecu.com

NEW QUESTION # 46
Which two statements are true about priority queuing (PQ)? (Choose two.)

• A. Traffic in the highest priority queue will experience the least amount of jitter and delay compared to traffic in the other queues.
• B. Traffic in all queues are always guaranteed a minimum bandwidth.
• C. Traffic in lower priority queues can be starved of bandwidth.
• D. Traffic in the highest priority queue is only reserved for voice traffic.

Answer: A,C

Explanation:
Explanation
Priority queuing (PQ) is a queuing method that establishes four interface output queues that serve different priority levels: high, medium, normal, and low. Traffic in the highest priority queue will experience the least amount of jitter and delay compared to traffic in the other queues, because PQ always services the higher-priority queues first. However, this can also cause traffic in lower priority queues to be starved of bandwidth, especially if the highest priority queue is oversubscribed. Traffic in the highest priority queue is not only reserved for voice traffic, but can also include network control and routing traffic. Traffic in all queues are not always guaranteed a minimum bandwidth, because PQ does not provide any bandwidth reservation mechanism.

NEW QUESTION # 47
In your network, video traffic is being marked with DSCP code AF31.
Based on industry standard practice, which code would you use to assign higher priority to VoIP traffic?

• A. DF
• B. AF11
• C. EF
• D. AF21

Answer: C

Explanation:
Explanation
The code that is commonly used to assign higher priority to VoIP traffic is EF, which stands for Expedited Forwarding. EF is a per-hop behavior (PHB) defined by the Differentiated Services (DiffServ) model for QoS.
EF provides low delay, low jitter, and low loss for real-time applications such as VoIP. EF is marked by setting the DSCP value to 101110, which corresponds to decimal 4678. AF31, which stands for Assured Forwarding class 3 low drop probability, is another PHB defined by DiffServ, but it provides lower priority than EF. AF31 is marked by setting the DSCP value to 011010, which corresponds to decimal 2678. DF, which stands for Default Forwarding, is a PHB defined by DiffServ that provides best-effort service for unmarked traffic. DF is marked by setting the DSCP value to 000000, which corresponds to decimal 078.
AF11, which stands for Assured Forwarding class 1 low drop probability, is another PHB defined by DiffServ, but it provides lower priority than EF and AF31. AF11 is marked by setting the DSCP value to 001010, which corresponds to decimal 1078.

NEW QUESTION # 48
Review the exhibit.

A service provider wants to provide L3VPN for two customers (indicated by red and green in the exhibit).
Referring to the exhibit, which statement is correct?

• A. LDP must be configured between PE and CE
• B. MP-BGP should be configured on all the service provider's routers (Ps and PEs).
• C. The two customers cannot use overlapping IP prefixes.
• D. The service provider's P routers are not aware of the customers' routes.

Answer: D

Explanation:
Explanation
Referring to the exhibit, the correct statement is that the service provider's P routers are not aware of the customers' routes. This is because P routers only need to forward MPLS packets based on their labels, without looking into their IP headers or VPN information. The P routers do not have any VRFs configured for the customers, nor do they participate in MP-BGP sessions with other PE routers. The PE routers are responsible for maintaining VRFs for each customer and for exchanging VPN routes with other PE routers using MP-BGP910.

NEW QUESTION # 49
Which network is reserved as a private network according to RFC1918?

• A. 172.16.1.0/9
• B. 172.15.1.0/24
• C. 193.168.1.0/24
• D. 10.254.1.0/24

Answer: D

Explanation:
Explanation
According to RFC1918, there are three network blocks reserved as private networks that are not allocated to any specific organization and are not routable on the public Internet. These are:
10.0.0.0/8 (10.0.0.0 - 10.255.255.255)
172.16.0.0/12 (172.16.0.0 - 172.31.255.255)
192.168.0.0/16 (192.168.0.0 - 192.168.255.255)
Out of these, only option B (10.254.1.0/24) falls within one of the private network blocks (10.0.0.0/8). Option A (172.16.1.0/9) is not valid because it exceeds the /12 prefix length of the private network block (172.16.0.0/12). Option C (193.168.1.0/24) is not valid because it does not belong to any of the private network blocks, and is actually assigned to RIPE NCC as a public network block . Option D (172.15.1.0/24) is also not valid because it does not belong to any of the private network blocks, and is actually assigned to ARIN as a public network block .

NEW QUESTION # 51
What is the function of LSR from an LDP perspective?

• A. The LSR distributes packets of LDP to its FEC peers.
• B. The LSR distributes labels of FEC to its LDP peers.
• C. The LSR distributes labels of LDP to its FEC peers.
• D. The LSR distributes packets of FEC to its LDP peers.

Answer: B

Explanation:
Explanation
The function of LSR from an LDP perspective is to distribute labels of FEC to its LDP peers. LSR stands for Label Switching Router, which is a router that forwards packets based on labels rather than IP addresses in an MPLS network. LDP stands for Label Distribution Protocol, which is a protocol that distributes labels for MPLS forwarding along the shortest path calculated by an IGP. FEC stands for Forwarding Equivalence Class, which is a group of packets that are forwarded in the same manner by an LSR. An LSR uses LDP to advertise the label mappings for each FEC to its LDP peers, which are other LSRs that have established an LDP session with it12.

NEW QUESTION # 53
Which two statements are true about link-state routing protocols? (Choose two.)

• A. The advertisement exchange is mainly triggered by a change in the network.
• B. Each router uses a reliable update mechanism to exchange topology information with its neighbors.
  C Link-state routing protocols mainly use hop-counts to determine the link cost
• C. A distance vector algorithm is very processor intensive compared to Dijkstra's algorithm.

Answer: A,B

Explanation:
Explanation
Link-state routing protocols are one of the two main classes of routing protocols used in packet switching networks for computer communications, the other being distance-vector routing protocols. Examples of link-state routing protocols include Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). The basic concept of link-state routing is that every node constructs a map of the connectivity to the network, in the form of a graph, showing which nodes are connected to which other nodes. Each node then independently calculates the next best logical path from it to every possible destination in the network.
Each collection of best paths will then form each node's routing table.
Two statements that are true about link-state routing protocols are:
The advertisement exchange is mainly triggered by a change in the network. Link-state routing protocols use a flooding mechanism to distribute information about the network topology to all routers in the same area or domain. This information is encapsulated in link-state packets (LSPs) or link-state advertisements (LSAs), which contain information about the router, its directly connected links, and the state of those links. LSPs or LSAs are sent only when there is a change in the topology, such as a link failure or recovery, or when a periodic refresh timer expires. This way, link-state routing protocols can quickly adapt to network changes and maintain an accurate and consistent view of the network.
Each router uses a reliable update mechanism to exchange topology information with its neighbors.
Link-state routing protocols use a reliable update mechanism to ensure that all routers receive and acknowledge the LSPs or LSAs sent by their neighbors. This mechanism involves sending hello messages to establish and maintain adjacencies with neighbors, sending acknowledgment messages to confirm the receipt of LSPs or LSAs, and requesting missing or outdated LSPs or LSAs from neighbors.
This mechanism ensures that all routers have a synchronized database of LSPs or LSAs, which is used to build a complete network connectivity map and to calculate the shortest path to destinations.

NEW QUESTION # 55
Which two features does IPsec provide? (Choose two.)

• A. protecting packets from modification
• B. protecting the length of packets from discovery
• C. controlling the path through the network
• D. hiding the content of packets from observation

Answer: A,D

Explanation:
Explanation
IPsec provides two main features: protecting packets from modification and hiding the content of packets from observation. IPsec protects packets from modification by using cryptographic algorithms to generate and verify message authentication codes (MACs) or digital signatures for each packet. These mechanisms ensure that the packets have not been tampered with or altered in transit by unauthorized parties. IPsec hides the content of packets from observation by using encryption algorithms to scramble the payload of each packet. This prevents eavesdroppers or interceptors from reading or analyzing the data carried by the packets12.
