Question:1.
A customer requests that sites are connected over an MPLS backbone using the MPLS AToM service. However, the network engineer advises that the MPLS L3VPN service may be better for this situation. Which characteristic of MPLS L3VPN may make it a better option from the Service Provider perspective ?
A.Reduction of operational complexity.
B.Support for multiple network layer protocols, such as IP,?IPX, and SNA
C.Customer Layer 2 information will be maintained over the service provider core.
D.Transparent to the customer
Answer: A
Question:2.
Refer to the exhibit. R1 and R2 have a static default route that is configured to point toward the ISP. Both R1 and R2 routers redistribute the default route into OSPF. R2 is the primary gateway toward the ISP and R1 is the backup gateway. All link metrics are the same. Which two steps ensure that traffic to the ISP flows through R2 when the network works properly? (Choose two.)
A.Modify the preference value of the default route on R1 so that it is less preferred than OSPF external routes.
B.Modify the preference value of the default route on R2 so that it is less preferred than OSPF external routes.
C.Redistribute the default route as a type 1 external route on R1 and a type 2 external route on R2.
D.Redistribute the default route as a type 2 external route on R1 and a type 1 external route on R2.
E.Redistribute the default route on R1 with a higher metric than the existing metric of the distributed default route on R2.
Answer:AD
Question:3
A network engineer is trying to optimize convergence.What action should be taken to overcome EBGP frequent session loss due to interface flapping between two different AS routers?
A.Tune the BGP session time-out.
B.Disable bgp fast-external-fallover.
C.Enable bgp fast-external-fallover.
D.Use disable-connected-check.
E.Enable neighbor fall-over.
Answer: B
Question:4
Refer to the exhibit. A company is deploying IPv6 using a dual-stack approach. OSPFv2 is used for IPv4 routing and is redistributed into the BGP IPv4 address family. The network engineer also needs to enable OSPFv3 for IPv6 routing using the same design that is used for OSPFv2. All prefixes in the OSPFv3 database must be redistributed into the BGP IPv6 address family at router R2, but R3 does not receive the loopback 0 IPv6 address of R2 via BGP. Which action will fix this problem?
A.redistribution of BGP routes into?OSPFv3
B.redistribution of OSPFv3 routes into?BGP with include-connected
C.mutual redistribution of OSPFv3 and BGP routes
D.redistribution of connected OSPFv3 routes
Answer: B
Question:5
A network engineer is tasked with supporting traffic discrimination over MPLS traffic engineering tunnels. To allocate restricted bandwidth to a certain type of traffic with no QoS degradation, which technique must be used?
A.integrated services
B.MPLS TE Diff-Serv full allocation model
C.MPLS TE Diff-Serv Russian doll model
D.IP precedence
E.class of service
Answer: C
Question:6
In an OSPF domain, four routers are running the OSPF protocol over a LAN switch in a broadcast domain. What is the expected output of executing the show ip OSPF neighbor command on the router that is neither a DR nor a BDR?
A.one FULL state, two 2WAY states
B.two FULL states, one 2WAY state
C.three FULL states
D.three 2WAY states
Answer: B
