質問 # 21
Which of the following statements about a Segment Routing SID is FALSE?
- A. An Adjacency-SID does not have to be configured.
- B. A Node-SID is usually associated with a router's system interface.
- C. A Prefix-SID can be configured directly as a label value or indirectly as an index.
- D. Adjacency-SID values are taken from the SRGB configured for the routing protocol.
正解：A
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.

正解：D
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 # 23
Which of the following statements about the Path Computation Element (PCE) is FALSE?
- A. The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.
- B. A stateful PCE can allow LSPs to reserve bandwidth.
- C. A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.
- D. A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.
正解：B
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.

- B. A Node-SID is usually associated with a router's system interface.
- C. A Prefix-SID can be configured directly as a label value or indirectly as an index.
- D. Adjacency-SID values are taken from the SRGB configured for the routing protocol.
正解：A

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 # 27
Which of the following statements about Multi-Protocol Label Switching networks is FALSE?
- A. The data is transparently carried from end to end.
- B. An LSP is a bi-directional tunnel that uses MPLS labels to forward data.
- C. An LSR forwards data based on the MPLS labels.
- D. MPLS uses a signaling protocol to exchange labels between routers.
正解：A
解説：
The data is transparently carried from end to end: This statement is not true, MPLS does not provide data transparency, which means that the data is not carried unmodified from end to end. MPLS uses labels to forward data, so the original IP packets are encapsulated in new MPLS packets, and the original IP headers are not visible at the egress LSR.
質問 # 28
Based on the configuration shown for routers R1 and R10, what valid flex-algo definitions exist in the network?
- A. One valid flex-algo definition, using te-metric as the link metric and including blue links.
- B. One valid flex-algo definition, using delay as the link metric and including green links.
- C. No valid flex-algo definitions, because of the conflicting parameters.
- D. Two valid flex-algo definitions, one uses te-metric as the link metric and includes blue links and the other uses delay as the link met includes green links.
正解：D
質問 # 29
Which of the following statements about a Segment Routing SID is FALSE?
- A. A local Node-SID can be configured directly as an MPLS label.
- B. All routers do NOT need to have the same SRGB range configured.
- C. A router advertises its local Node-SID as a local SRGB and an index only if it is configured as an index.
- D. A local Node-SID can be configured as an index.
正解：C
解説：
A router advertises its local Node-SID as a local SRGB and an index only if it is configured as an index: This statement is not true, A router will advertise its local Node-SID as a local SRGB and an index, whether it is configured as an index or not.
質問 # 30
Which of the following statements about path definitions is FALSE?
- A. The path hops can be defined by either the system or physical interface IP address.
- B. Once a path is associated with an LSP, it cannot be used by other LSPs.
- C. In addition to the hops defined in the path list, the head-end and tail-end routers are implicitly added.
- D. A loose hop is one that does not have to be directly adjacent to the previous hop in the path list
正解：A
質問 # 31
Examine the exhibit. Based upon the configuration, which routers will the LSP go through?
- A. R1, R2, R4 and R6
- B. R1, R3, R2, R5, R4 and R6
- C. R1, R2, R5 and R6
- D. R1, R3, R4 and R6

質問 # 32
Based on the exhibit, and given that the system IP address of router RIO is 10.10.10.10, which of the following statements is FALSE?
- A. The Node-SID assigned to router RIO for flex-algo instance 129 is 524338.
- B. Router RIO participates in flex-algo instance 130.

- D. Router Rl participates in at least two flex-algo instances.
正解：A
質問 # 33
Which of the following statements about Segment Routing tunnels is FALSE?
- A. For a Segment Routing tunnel, an intermediate router will always forward the packet based on the best IGP path.
- B. A Segment Routing tunnel can be defined by multiple Node-SIDs.
- C. A Segment Routing tunnel defined by a Node-SID uses the shortest IGP Path.
- D. A Segment Routing tunnel can be defined by a combination of Node-SIDs and Adjacency-SIDs.
正解：A
解説：
an intermediate router in a Segment Routing tunnel may forward packets based on the specific SIDs defined in the Segment Routing tunnel and not always the best IGP path.
質問 # 34
Which of the following statements about primary and secondary SR-TE LSP paths is FALSE?
- A. The primary path is always preferred over a secondary pa
- B. Only one LSP path forwards the traffic at any time,
- C. Up to three paths can be configured for a given SR-TE LS
- D. Preference values can be configured for non-standby secondary paths.
正解：C
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 # 35
Which of the following statements about Segment Routing is FALSE?
- A. Intermediate routers do not maintain any tunnel informal
- B. No path signaling is required to establish an SR tunnel.
- C. For TE-constrained tunnels, each data packet typically carries a single MPLS label to specify the tunnel path.
- D. A link-state IGP is required to distribute SID information.
正解：A
解説：
Intermediate routers do not maintain any tunnel informal: this statement is false, Intermediate routers do maintain tunnel information, such as the Forwarding Information Base (FIB) to forward the packets according to the path specified in the packets.
質問 # 36
Which of the following is NOT an advantage of using a PCE for the computation of TE-constrained LSP paths, as compared to using CSPF locally on the PE router?
- A. The ability to create LSP paths with bandwidth reservation
- B. The ability to create cross-area TE-constrained LSP paths
- C. The ability to create LSPs with primary and secondary paths
- D. The ability to ensure that some LSP paths are disjoint
正解：A
解説：
PCE does not have the capability to reserve bandwidth, This is a function of a Resource Reservation Protocol (RSVP) or a Label Distribution Protocol (LDP) and is done locally on the PE.
PCE can have advantages such as:
The ability to create cross-area TE-constrained LSP paths
The ability to create LSPs with primary and secondary paths
The ability to ensure that some LSP paths are disjoint
it can be used to optimize the path computation by centralizing the path calculation and by taking into account a global view of the network.
