Question 1

DHCP snooping is a security feature that can be used to defend against various attacks, including: (Multiple Choice)

A. Starvation attacks by changing the CHADDR field value

B. Bogus DHCP server attacks

C. Man-in-the-middle attacks and IP/MAC spoofing attacks

D. TCP flag attacks

Correct Answer: A,B,C

Question 2

On the MPLS network shown in the following figure, which of the following statements are true? (Multiple Choice)

A. The switch's peer LDP ID is the MPLS LSR ID of the peer device.

B. The switch uses the directly-connected interface to set up a TCP connection.

C. The switch's peer LDP ID is an interface IP address of the peer device.

D. The switch uses the LSR ID to set up a TCP connection.

Correct Answer: A,B

Question 3

On the traditional IP network, the BE mode cannot distinguish communication types or meet requirements of applications. The emergence of QoS technology is committed to solving this problem.

A. FALSE

B. TRUE

Correct Answer: B

Question 4

Which of the following statements regarding Service Chain of the Agile Controller are true? (Multiple Choice)

A. A service device processes the service flows directed to it by an orchestration device. Generally, firewall, antivirus, and online behavior management devices can function as service devices.

B. The Service Chain component uses a user control list (UCL) to implement access control by user level. The ACL rules are defined based on the source security group, destination security group, and port number.

C. An orchestration device, usually a switch, directs service flows to a service device.

D. A service chain indicates the service data passing through the GRE tunnel.

Correct Answer: A,B,C

Question 5

When configuring MPLS VPN, the administrator configures the following commands.
Which of the following statements is false?

A. This command binds G0/0/1 and G0/0/2 on the PE to the VPN instances assigned for the customer network.

B. After an interface is bound to a VPN instance, the interface becomes a private network interface, which can be assigned with a private network address and run a private network routing protocol.

C. If an interface is unbound from a VPN instance, the device does not automatically clear IPv4 or IPv6 configurations on the interface.

D. This command is generally configured on a PE.

Correct Answer: C

Question 6

MPLS is short for multiprotocol label switching.
Which of the following statements regarding MPLS labels are true? (Multiple Choice)

A. An MPLS label, carried in a packet header, does not contain topology information and is globally significance.

B. Similar to VPI/VCI in ATM packets and DLCI in Frame Relay packets, an MPLS label is a connection identifier.

C. MPLS has multiple label distribution protocols, such as, Label Distribution Protocol (LDP).

D. An MPLS label is a short fixed-length identifier with only local significance, and is used to uniquely indicate the FEC to which a packet belongs.

E. MPLS supports single-layer labels and multi-layer labels.

Correct Answer: B,C,D,E

Question 7

In the SDN network architecture, which device is used to calculate the path and deliver the flow table?

A. Device

B. Orchestrator

C. Controller

D. Application server

Correct Answer: C

Question 8

Complex traffic classification means that packets are classified based on the quintuple including the source and destination addresses, source and destination port numbers, and protocol type. It is usually deployed on the network core.

A. FALSE

B. TRUE

Correct Answer: A

Question 9

After add interface GigabitEthernet0/0/1 is configured in the trust zone view of the USG series firewall, GigabitEthernet0/0/1 does not belong to the local zone anymore.

A. FALSE

B. TRUE

Correct Answer: A
