Question 2

A router is connected to two EBGP peers through two parallel serial cables. What method can be used to achieve bidirectional load balancing between the EBGP peers?

Accepted Answer

A)  Run the ebgp-load-balance command on the EBGP peers. 
B)  No method is needed. BGP automatically implements load balancing among different Ass through available links. 
C)  Establish an EBGP peer relationship through loopback interfaces, and configure the loopback interfaces as update sources. In each AS, import two equal-cost routes to the loopback interface of each EBGP peer to the IGP process. In addition, run the ebgp-max-hop and next-hop-local commands. 
D)  Configure an EBGP peer relationship through loopback interfaces, and configure the loopback interfaces as update sources. In each AS, enable two equal-cost routes to the loopback interface on each EBGP peer in the IGP process. In addition, run the next-hop-local command.

Question 3

If an ABR is a Type 5/7 LSA translator in an NSSA, the ABR can aggregate Type 5 LSAs converted from Type 7 LSAs.

Accepted Answer

A) True 
 B)False

Question 4

Which of the following statements correctly describes the corresponding MPLS TTL processing mode?

Accepted Answer

A)  On an MPLS VPN, if the structure of the MPLS backbone network needs to be shielded, the Uniform mode is recommended for VPN packets. 
B)  In Uniform mode, when IP packets enter an MPLS network, the ingress node decrements the IP TTL by one and the MPLS TTL field has a fixed value. 
C)  The TTL field in an MPLS label serves the same function as that in an IP packet header. That is, the TTL is used to prevent loops on an MPLS network. 
D)  In Pipe mode, when IP packets enter an MPLS network, the ingress node decrements the IP TTL by one and copies this new value to the MPLS TTL field.

Question 5

A Bridge Domain (BD) in a VXLAN can map to multiple VNIs.

Accepted Answer

A) True 
 B)False

Question 6

Switches use IPSG to verify the source address of IP packets. IPSG obtains the binding table by listening to the address resolution process.

Accepted Answer

Accepted Answer

A) True 
 B)False

Question 8

 B)False

Question 9

What is the destination IP address of routing update packets sent by RIPv2?

Question 11

Router HW1 functions as an MPLS LSR router on the carrier's network. The router receives a labelled packet, but the label entry does not exist in the router's LFIB. Given this information, how will the router process the packet?

Accepted Answer

A)  Router HW1 discards the packet. 
B)  Router HW1 uses the default label to forward the packet. 
C)  Router HW1 removes the label, searches the FIB, and uses the destination IP address to forward the packet.
