質問 # 24
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?
- A. The head end will continue forwarding traffic to the current next-hop indefinitely, which will be discarded at the point of failure.
- B. The head end will periodically try to calculate a new path at a rate defined by the retry timer.
- C. The head end will continue forwarding traffic to the current next-hop indefinitely, and R2 will redirect the traffic to R3 after IGP reconvergence.
- D. The head end will periodically try to calculate a new path at a rate defined by the resignal timer.
正解：A
解説：
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.
質問 # 25
Which of the following statements about SR-TE administrative constraints is FALSE?
- A. Shared-Risk-Link Groups are only taken into account when calculating the secondary path.
- B. The head-end router may calculate a path that takes into account max hop count and bandwidth constraints.
- C. A strict hop must be adjacent to the previous hop in the list.
- D. The TE metric for a link is by default the same as the IGP metric.
正解：A
解説：
Shared-Risk-Link Groups(SRLG) is taken into account when calculating both primary and secondary path to avoid routing over the same physical link.
質問 # 26

質問 # 27
Which of the following is not required to be advertised by a router participating in Segment Routing?
- A. Local Node-SID
- B. Support for SR-MPLS for IPv4 or IPv6, or SRv6
- C. Adjacency-SIDs
- D. SRGB when SRv6 is configured
正解：D
解説：
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.
質問 # 28
Which of the following statements about a Segment Routing SID is FALSE?
- A. Adjacency-SID values are taken from the SRGB configured for the routing protocol.
- B. A Prefix-SID can be configured directly as a label value or indirectly as an index.
- C. A Node-SID is usually associated with a router's system interface.
- D. An Adjacency-SID does not have to be configured.
正解：D
解説：
An Adjacency-SID does not have to be configured: this statement is not true, An Adjacency-SID is associated with a neighbor router, it is used to identify an adjacency between two routers. An Adjacency-SID must be configured to identify the adjacency.
質問 # 29
Which of the following statements about the Path Computation Element (PCE) is FALSE?
- A. A stateful PCE can allow LSPs to reserve bandwidth.
- B. A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.
- C. A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.
- D. The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.
正解：A
解説：
Stateful PCE can monitor the existing LSPs and trigger necessary repairs and re-optimizations, but it does not have the capability to reserve bandwidth.
質問 # 30

- A. Router Info
- B. Traffic Engineering Info
- C. Extended Link Info
- D. Extended Prefix Info
正解：A
解説：
This type of advertisement carries a router's local SRGB information, which is used to distribute information about the local SID allocation range
質問 # 31
Which of the following is NOT one of the main goals of traffic engineering?
- A. Avoiding potential congestion points in the network.
- B. Defining traffic paths based on various constraints.
- C. Using the shortest possible path through the network to the destination.
- D. Utilizing redundant links.
正解：C
質問 # 32
The exhibit shows the fast re-route configuration on router R1, in which both R-LFA and TI-LFA have been enabled. Assume that there are multiple potential backup paths for a given prefix. Which of the following options will router R1 use?
- A. A D-LFA path that would not coincide with the path after IGP re-convergence.
- B. A standard LFA path that would not coincide with the path after IGP re-convergence.
- C. A D-LFA path that would coincide with the path after IGP re-convergence.
- D. An R-LFA path that would not coincide with the path after IGP re-convergence.
正解：C
解説：
The exhibit shows that both R-LFA and TI-LFA have been enabled on router R1. R-LFA (Remote Loop-Free Alternate) is a method that is used to protect the active segment of a tunnel, and it allows the router to find a backup path that coincides with the path that will become active after IGP reconvergence. TI-LFA (Topology Independent LFA) is a method that is used to protect an end-to-end multi-segment tunnel, it allows the router to find a backup path that does not rely on the IGP topology, but on the segment routing topology.
With R-LFA and TI-LFA enabled, router R1 will use a D-LFA (Dual-Loop-Free Alternate) path, which is a combination of both R-LFA and TI-LFA, this path will coincide with the path after IGP re-convergence.
A standard LFA, R-LFA, and D-LFA which do not coincide with the path after IGP re-convergence are not the options.
質問 # 33
Which of the following statements about the operation of seamless-BFD is FALSE?
- A. A seamless-BFD template needs to be configured on the head-end of the LSP.
- B. To be able to respond to seamless-BFD messages, a router must be configured as a reflector.
- C. The routing protocol (OSPF or IS-IS) is used to carry the reflector discriminator information.
- D. Seamless-BFD responses are sent back using the LSP label stack.
正解：D
解説：
Seamless-BFD is a mechanism that allows the detection of faults in MPLS LSPs more quickly by using BFD (Bidirectional Forwarding Detection) protocol. Seamless-BFD responses are sent back using the MPLS data-plane, not the LSP label stack.
質問 # 34
Which of the following statements about path definitions is FALSE?
- A. In addition to the hops defined in the path list, the head-end and tail-end routers are implicitly added.
- B. The path hops can be defined by either the system or physical interface IP address.
- C. Once a path is associated with an LSP, it cannot be used by other LSPs.
- D. A loose hop is one that does not have to be directly adjacent to the previous hop in the path list
正解：B
質問 # 35

質問 # 37
Which of the following statements about primary and secondary SR-TE LSP paths is FALSE?
- A. Preference values can be configured for non-standby secondary paths.
- B. Only one LSP path forwards the traffic at any time,
- C. The primary path is always preferred over a secondary pa
- D. Up to three paths can be configured for a given SR-TE LS
正解：D
解説：
Typically, in SR-TE, only two paths can be configured for a given SR-TE LSP: primary path and secondary path. The primary path is used for normal traffic forwarding, and the secondary path is used as a backup in case the primary path fails. Only one LSP path forwards the traffic at any time.
質問 # 38
Which of the following statements about enabling and using traffic engineering for Segment Routing is FALSE?
- A. One interface can belong to an admin group and SRLG group at the same time.
- B. Bandwidth availability as a link attribute cannot be configured.
- C. The interfaces used for SR-TE LSPs have to be added to the MPLS context.
- D. A link attribute has to be assigned to a particular interface under the [/configure router interface] context
正解：B
解説：
Bandwidth availability can be configured as a link attribute in SR-TE, it is used to control the amount of traffic that can be sent over a particular link.
質問 # 39
Which of the following statements about segment routing fast re-route is FALSE?
- A. Fast re-route is a temporary fix that becomes active for a short period of time after a local network failure.
- B. The parameter "max-sr-frr-labels" limits the number of labels that R-LFA can add to the data packet encapsulation.
- C. On a Nokia 7750 SR, R-LFA and TI-LFA can be enabled independently of each other.
- D. Fast re-route typically protects the active segment of a tunnel, but under certain conditions it can protect an end-to-end multi-segment tunnel instead.
正解：C
解説：
On a Nokia 7750 SR, R-LFA and TI-LFA cannot be enabled independently; they must be enabled together. The parameter "max-sr-frr-labels" limits the number of labels that R-LFA can add to the data packet encapsulation.
