Question 142

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

On an MPLS VPN, if the structure of the MPLS backbone network needs to be shielded, the Uniform mode is recommended for VPN packets.

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.

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.

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 143

Which of the following statements regarding CE dual-homing features is false?

The VRFs of two PEs connected to the same CE can belong to different VPNs.

In the CE dual-homing networking, loops may occur. You can use route-tag resolve this issue.

A CE dual-homing network where a CE is connected to two PEs ensure high network reliability.

A CE connects to the backbone network through two links that work in load balancing or primary/secondary mode.

Question 146

Two community filters are configured as follows:

ip community-filter 1 permit 100:1 200:1 ip community-filter 2 permit 100:1 ip community-filter 2 permit 200:1

Which of the following statements regarding the community filters are true? (Choose two.)

A BGP route matches community-filter 2 only when it carries the Community attribute values of 100:1 and 200:1.

A BGP route matches community-filter 1 only when it carries the Community attribute value of 100:1 or 200:1, or both.

A BGP route matches community-filter 1 only when it carries the Community attribute values of 100:1 and 200:1.

Question 147

Which of the following statements regarding RD filters are true? (Choose two.)

The relationship between the rules of an RD filter is "OR."

If an RD filter is configured but the RD of routes does not match any RD defined in the RD filter, the default matching result is "permit."

Routes are filtered according to the configuration order of multiple rules.

If an RD filter is not configured but used to filter routes, the matching result is "deny".

Question 148

Which of the following statements is true regarding the domain authentication mode md5 hello command in the IS-IS process?

This command enables IS-IS Hello PDUs to carry authentication information.

IS-IS SNP and LSP can be flooded normally only when the domain authentication mode and password of all routers in the same routing domain are MD5 and hello.

IS-IS authentication cannot be applied to IPv6 environments.

Routing domain authentication enables Level-1 and Level-2 SNPs and LSPs to carry authentication information.
