Question 6

When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two )

A. Serialization delay depends not only on the line rate of the interface but also on the size of the packet

B. Serialization delay is the time required to transmit the packet on the physical media.

C. Serialization delays are invariable because they depend only on the line rate of the interface

D. Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.

Correct Answer: D,E

Question 7

A network engineering team is designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS Traffic Engineering Fast Reroute solution has the same failover Tailback times as a traditional SONET/SDH network (around 50 msec).

B. next-hop tunnel

C. TE backup tunnel

D. FRR backup tunnel

Correct Answer: A

Question 8

You are tasked to design a QoS policy for a service provider so they can include it in the design of their MPLS core network If the design must support an MPLS network with six classes, and CEs will be managed by the service provider, which QoS policy should be recommended?

A. map IP CoS bits into the IP Precedence field

B. map IP precedence bits into the DSCP field

C. map flow-label bits into the Exp field

D. map DSCP bits into the Exp field

Correct Answer: D

Question 9

Which solution provides interoperability and protects data traffic from eavesdropping?

A. Cisco MPLS TE

B. GET-VPN

C. DMVPN

D. IPsec-VPN

Correct Answer: D

Question 10

For which two reasons do you choose L2TPv3 over other technologies for a VPN solution? (Choose two)

A. The VPN solution should support Frame Relay to Ethernet pseudowrite connections.

B. The VPN solution requires multipoint Ethernet LAN service

C. The VPN solution does not contain MPLS on the network core.

D. The VPN solution should tunnel Layer 2 frames and Layer 3 packets

E. The VPN solution should be industry standard.

Correct Answer: C,E

Question 11

You must measure the amount of the traffic that a mode packet gateway produces when mobile phones access the service provides internal applications, rather than the Internet. which action do you to allow this visibility?

A. Collect traffic information that is related to internal server IP addresses with NetFlow

B. Poll OID that is configured for internal servers with SNMP

C. Collect information about traffic to the service provider marked with IP precedence

D. Measure traffic characteristics of known internal servers with IP SLA

Correct Answer: A

Question 12

Correct Answer: C

Question 15

You are designing a data center migration from one location to another, which requires all existing VLANs spanned to the new data center to maintain host IP addressing. Two temporary Gigabit Ethernet circuits are available to extend the VLANs at Layer 2 to the location as trunk links between core switches in each location. Which solution provides maximum fault isolation between the two data centers to ensure a Layer Issue in one data center does not affect the other during the migration?

A. Run the dual links as multichassis Etherchannel trunk between core switches within each location

B. Perform HSRP filtering over the trunk links to maintain active HSRP gateways within each data center for each VLAN

C. Enable STP PortFast on host ports within each data center
