A. True
B. False

Answer: B

NEW QUESTION # 316
A 32-bit MPLS header consists of a 20-bit label used for packet forwarding, a 3-bit EXP field that identifies the IP packet priority, a 1-bit bottom-of-stack flag that identifies the last label, and an 8-bit TTL field. Which statement regarding the TTL field is correct?

A. This field limits the LSR.
B. This field is used to prevent packet forwarding loops, similar to the TTL field in an IP header.
C. This field is used for label management.
D. This field is used to control the upstream device in label distribution.

Answer: B

Explanation:
TheMPLS headerconsists of:
Label (20 bits)- Label value used for forwarding.
EXP (3 bits)- QoS field (Class of Service).
S bit (1 bit)- Bottom-of-Stack indicator.
TTL (8 bits)-Time-to-Live, similar to the TTL field in the IP header.
Function of TTL in MPLS:
It is used toprevent infinite loops.
Every LSRdecrementsthe TTL by 1.
When TTL reaches0, the packet isdiscarded.
This mirrors the behavior of IP TTL and ensures loop prevention in MPLS networks.
Correct answer: D. This field is used to prevent packet forwarding loops, similar to the TTL field in an IP header.

NEW QUESTION # 317
In a scenario where SR Policies are dynamically established through the controller, which of the following statements about the SR Policy solution architecture is incorrect?

A. The controller uses BGP IPv6 SR Policy to deliver SR Policy information, such as the color, headend, and endpoint information.
B. The controller uses BGP-LS to collect tunnel topology information and computes SR Policy paths.
C. The controller uses NETCONF to deliver configurations such as service interfaces and routing policies.
D. The controller uses telemetry to deliver information such as SRv6 SIDs to construct SID entries.

Answer: D

Explanation:
Comprehensive and Detailed
✔ SR Policies are dynamically computed and delivered by the SDN controller in an SR-MPLS or SRv6 network.
✔ Correct Statements:
✅ (A) NETCONF is used for delivering configurations like routing policies and service interfaces.
✅ (B) BGP-LS (Link-State) is used to collect topology and compute SR Policies.
✅ (D) BGP IPv6 SR Policy distributes SR policy attributes like color, headend, and endpoints.
✔ Why Is (C) Incorrect?
❌ (C) The controller does not use telemetry to deliver SID entries-telemetry is used for real-time monitoring, not path computation.

NEW QUESTION # 318
Router RL runs the OSPF protocol and uses the display ip routing-tabe command to view the router RL's routing table , the following information about OSPF in the routing table is described correctly as ?

A. In the routing table, the routing table entries identified with the 'OSPF identifier' can be learned through the 1/2/3/5 LSA to
B. In the routing table, used The 'OSPF' identifier identifies a route table entry that can only pass a Type 1 LSA
C. In the routing table, Route table entries identified with the "O_ASE identifier can only be learned through routing introduction
D. In the routing table, the routing table entries identified by the OSPF identifier can only be learned through the 3 types of LSAs to

Answer: C
