السؤال #1
How does Cisco MPLS TE use OSPF extensions to allow for optimized transit between a headend router and a destination router?
A. SBR Summary LSAs share OSPF domain information so that the two routers know how to reach each other during tunnel setup
B. paque LSAs calculate and establish unidirectional tunnels that are set according to the network constraint
C. etwork LSAs share RSVP information to build the tunnel between the two routers
D. outer LSAs share router link advertisements to each router within the MPLS environment so that tunnels can be built bidirectionally

السؤال #3
An engineer must implement QoS to prioritize traffic that requires better service throughout the network. The engineer stated by configuring a class map to identify the high-priority traffic. Which additional tasks must the engineer perform to implement the new QoS policy?
A. ttach the class map to a policy map that designates the action to be taken on the classified traffic and then attach the policy map to an interface using a service policy
B. ttach the class map to a policy map that sets the minimum bandwidth allocated to the classified traffic and designates the action to be taken on the traffic
C. ttach the class map to a policy map within a VRF to segregate the high-priority traffic and then attach the policy map to an interface in another VRF
D. reate a route map to manipulate the routes that are entered into the routing table and then attach the route map to an interface using a service policy

How does Inter-AS Option-A function when two PE routers in different autonomous systems are directly connected?
A. he two routers establish an MP-EBGP session to share their customers' respective VPNv4 routes
B. he two routers share all lnter-ASVPN4 routes and redistribute routes within an IBGP session to provide end-to-end reach
C. he two routers share VPN4 routes over a multihop EBGP session and set up an Inter-AS tunnel using one another's label
D. he two routers treat one another as CE routers and advertise unlabeled Pv4 routes through an EBGP session

السؤال #6
A new PE router is configured to run OSPF as an IGP with LDP on all interfaces. The engineer is trying to prevent black holes after convergence when the PE device loses an LDP session with other PE routers. Which action must the engineer take to implement LDP session protection on a new PE router?
A. onfigure the mpls ldp session protection and mpls label protocol ldp commands on the new PE router that connect to the CE routers
B. onfigure the new PE router with the mpls ldp session protection command on interfaces with directly connected neighbors
C. onfigure the new PE router with the mpls ldp session protection command and on neighboring routers that connect to this new PE router
D. onfigure the mpls ldp discovery targeted-hello accept and mpls ldp session protection commands on the interfaces on the new PE router that connect to the CE routers

B. nable bidirectional forwarding detection on each device
C. efine VRFs on each device to separate the traffic
D. efine the site of origin on each interface

Which two features describe TI-LFA? (Choose two.)
A. I-LFA leverages the post-convergence path that carries data traffic after a failure
B. nlike RLFA TI-LFA works without the PQ node and provides double segment failure protection
C. l-LFA uses PQ or P and Q nodes on the post-convergence path to compute the backup path
D. I-LFA works with point of local repair when the PQ node supports only LDP capability
E. ost-convergence, T-LFA considers the next-hop neighbor to calculate the backup repair path
