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.QUESTION 24Which 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?  The ability to create cross-area TE-constrained LSP paths  The ability to create LSP paths with bandwidth reservation  The ability to create LSPs with primary and secondary paths  The ability to ensure that some LSP paths are disjoint 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 pathsThe ability to create LSPs with primary and secondary pathsThe ability to ensure that some LSP paths are disjointit can be used to optimize the path computation by centralizing the path calculation and by taking into account a global view of the network.QUESTION 25OSPF type-10 Opaque LSAs can carry different types of advertisements. What type of advertisement carries a router’s local 5RGB information?  Extended Prefix Info  Router Info  Extended Link Info  Traffic Engineering Info This type of advertisement carries a router’s local SRGB information, which is used to distribute information about the local SID allocation rangeQUESTION 26Which of the following statements about Segment Routing is FALSE?  No path signaling is required to establish an SR tunnel.  Intermediate routers do not maintain any tunnel informal  A link-state IGP is required to distribute SID information.  For TE-constrained tunnels, each data packet typically carries a single MPLS label to specify the tunnel path. 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.QUESTION 27When OSPF is used to support Segment Routing, the first byte of the link-state ID associated with each of the opaque LSAs indicates the type of information being advertised. Which of the following associations between the first-byte value and its meaning is FALSE?  Value 1 – Traffic Engineering  Value 4 – Router Info  Value 7 – SRGB Range  Value 8 – Extended Link Info Value 8 – Extended Link Info: This statement is not true, value 8 is not used to indicate Extended Link Info. It is used for different types of information, such as Link-Local/Remote Identifiers (LLS/RLS) Identifiers and Node SID/Adj-SID.QUESTION 28Which of the following is NOT a valid option to steer traffic into a flex-algo segment-routing tunnel?  Using a flex-algo Node-SID as an explicit hop in the path definition of an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.  Specifying the flex-algo instance ID as an additional TE constraint for an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.  Configuring and applying a VRF import policy to a VPRN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.  Configuring and applying a VSI import policy to an EVPN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol. Applying a VSI import policy to an EVPN service and enabling the sr-is-is or sr-ospf tunnel type for the service is not a valid option for steering traffic into a flex-algo segment-routing tunnel, VSI is not related to flex-algo SR.QUESTION 29Loopfree-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?  Only segments defined by a Node-SID.  Only segments defined by an Adjacency-SID.  Segments defined by a Node-SID and segments defined by an Adjacency-SID.  No segments, unless segment-routing fast-reroute is also explicitly enabled. 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.QUESTION 30Based on the exhibit, which of the following is a viable option for the Path Computation Element (PCE) to obtain all the necessary topology and traffic-engineering information from the network, so that it can calculate LSP paths on behalf of the PE routers?  Establishing an IGP adjacency with router R2  Establishing IGP adjacencies with routers R1 and R2  Establishing a BGP session using the BGP-LS address family with router R3  Establishing BGP sessions using the BGP-LS address family with routers R3 and R4 QUESTION 31Which of the following list of SR-TE attributes has to be advertised among routers?  Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to.  Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to.  Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to, link status up/down.  Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to, link status up/down. In SR-TE, routers need to advertise certain attributes of their links to other routers in the network in order to calculate traffic-engineered paths. These attributes include:Administrative groups that each link belongs to: This information is used to restrict the use of certain links to specific traffic types or groups.TE metric of links: This information is used to calculate the cost of using a particular link for a traffic-engineered path.Bandwidth availability of each link: This information is used to control the amount of traffic that can be sent over a particular link.SRLG that each link belongs to: This information is used to avoid routing over the same physical link. Link status up/down is not needed to be advertised as it is part of the IGP protocol and is used to check the reachability of a link.QUESTION 32To create a flex-algo instance in a network, which of the following configuration steps is mandatory?  Configuring the proper values for the shared-risk link groups (SRLGs) that will define the flex-algo topology.  Configuring at least one router in the network to create and advertise the flex-algo definition.  Specifying whether the LSP paths will be computed locally or by an external path computation element (PCE).  Configuring LSPs between every pair of PE routers. To create a flex-algo instance in a network, it’s mandatory to configure at least one router in the network to create and advertise the flex-algo definition, This is the first step in creating a flex-algo instance, and it’s done by defining the flex-algo instance and its properties on one or more routers in the network.The other steps are important to fine-tune the flex-algo instance, but not mandatory to create it.Configuring the proper values for the shared-risk link groups (SRLGs) that will define the flex-algo topology.Specifying whether the LSP paths will be computed locally or by an external path computation element (PCE).Configuring LSPs between every pair of PE routers.QUESTION 33Based 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?  Router Rl participates in at least two flex-algo instances.  Router RIO participates in flex-algo instance 130.  The Node-SID assigned to router RIO for flex-algo instance 129 is 524338.  The underlying routing protocol being used in the network for segment routing is IS-IS. QUESTION 34Which of the following statements about primary and secondary SR-TE LSP paths is FALSE?  Only one LSP path forwards the traffic at any time,  Up to three paths can be configured for a given SR-TE LS  The primary path is always preferred over a secondary pa  Preference values can be configured for non-standby secondary paths. 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.QUESTION 35The 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 standard LFA path that would not coincide with the path after IGP re-convergence.  An R-LFA path that would not coincide with the path after IGP re-convergence.  A D-LFA path that would not coincide with the path after IGP re-convergence.  A D-LFA path that would coincide with the path after IGP re-convergence. 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.QUESTION 36Which of the following steps is NOT required when configuring IS-IS to support Segment Routing?  MPLS label range reserved for Segment Routing.  Enable interfaces used for Segment Routing under  The flooding scope of Segment Routing information.  The Segment Routing Global Block range. Enable interfaces used for Segment Routing under: This step is not required, enabling interfaces used for Segment Routing is not necessary as the IS-IS protocol already takes care of the flooding of the routing information.QUESTION 37Which of the following statements about a Segment Routing SID is FALSE?  A Node-SID is usually associated with a router’s system interface.  A Prefix-SID can be configured directly as a label value or indirectly as an index.  Adjacency-SID values are taken from the SRGB configured for the routing protocol.  An Adjacency-SID does not have to be configured. 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.QUESTION 38Based upon the exhibit, which of the following statements regarding the configuration is FALSE?  Traffic engineering information will only be advertised for the interfaces that have both MPLS and RSVP enabled.  The Node-SID assigned to this router is the second label in the defined range.  Traffic engineering has been enabled on this router.  Adjacency-SID labels will not be advertised as they have not been defined under the physical interfaces.  Loading … To pass the Nokia 4A0-116 certification exam, candidates must demonstrate their understanding of the fundamentals of Nokia Segment Routing technology, including its architecture, protocols, and deployment models. 4A0-116 exam also tests the candidate's ability to configure and troubleshoot Nokia Segment Routing networks, as well as their knowledge of advanced topics such as network slicing and path optimization.
