최신 Nokia Service Routing Architect 4A0-116 무료샘플문제 (Q38-Q43):

질문 # 38
Which of the following is not required to be advertised by a router participating in Segment Routing?

  • A. SRGB when SRv6 is configured
  • B. Adjacency-SIDs
  • C. Local Node-SID
  • D. Support for SR-MPLS for IPv4 or IPv6, or SRv6

정답：A

설명：
SRGB when SRv6 is configured: This is not required to be advertised, SRGB(Segment Routing Global Block) is only used for SR-MPLS and is not needed when SRv6 is configured. Instead, SRv6 uses the IANA-assigned IPv6 address space.


질문 # 39
Loopfree-alternate has been enabled on a router for its link-state routing protocol. For which types of segments will the router attempt to find a backup path, so that they become protected by fast re-route?

  • A. Only segments defined by an Adjacency-SID.
  • B. No segments, unless segment-routing fast-reroute is also explicitly enabled.
  • C. Segments defined by a Node-SID and segments defined by an Adjacency-SID.
  • D. Only segments defined by a Node-SID.

정답：C

설명：
Loopfree-alternate is a mechanism that enables fast re-route for link-state routing protocols, it allows the router to find a backup path for both Node-SID and Adjacency-SID segments, so that they become protected by fast re-route.


질문 # 40
An SR-TE LSP with a path definition that includes router R4 as a loose hop and for which Seamless-BFD has been enabled is following the path shown in the exhibit. What happens after router R4 fails if the routers along the path follow the default behavior?
4A0-116-16b8a0a749334fc9285fca7235d18e72.jpg

  • A. The head end will periodically try to calculate a new path at a rate defined by the retry timer.
  • B. The head end will periodically try to calculate a new path at a rate defined by the resignal timer.
  • C. The head end will continue forwarding traffic to the current next-hop indefinitely, which will be discarded at the point of failure.
  • D. The head end will continue forwarding traffic to the current next-hop indefinitely, and R2 will redirect the traffic to R3 after IGP reconvergence.

정답：C

설명：
When an SR-TE LSP with Seamless-BFD enabled, the BFD sessions are established between the routers along the path to detect any failures quickly. If a failure happens in the path, the router will stop forwarding the traffic and send a BFD control packet to the head-end router. In this case, R4 failed, BFD sessions will detect the failure and send a message to the head-end router, but since R4 is a loose hop, the path doesn't have to be re-calculate. The head-end router will continue forwarding traffic to the current next-hop, R2, which will be discarded at the point of failure (R4) as it doesn't know about the failure. And the traffic will not be redirected to R3 after IGP reconvergence.


질문 # 41
Based on the exhibit, which of the following statements about fast re-route for flex-algo instance 129 is TRUE?
4A0-116-f8436661246d601a4a2fabce7faba834.jpg

  • A. Standard LFA and remote-LFA are enabled on router R1; fast re-route is not enabled on router R2.
  • B. Only standard LFA is enabled on router R1; fast re-route is not enabled on router R2.
  • C. Standard LFA and remote-LFA are enabled on router R1; standard LFA and TT-LFA are enabled on router R2.
  • D. Only standard LFA is enabled on both routers R1 and R2.

정답：A


질문 # 42
The exhibit highlights in blue the primary path of a segment going from router S to router D.
The exhibit also shows a backup path. The protected link fails and fast re-route is triggered on router S. If the backup path has been calculated using standard LFA, how many SIDs are included in the label stack of the data packet forwarded to router R1?
4A0-116-c81cae616e607cdfd4b5903aab42384c.jpg

  • A. 0
  • B. 1
  • C. 2
  • D. 3

정답：D
