Refined CCIE Service Provider 400-201 dumps

Q1. Refer to the exhibit. 

The prefix 10.1.1.64/28 should be advertised to the PE router, yet the prefix is not being received by the PE. Which configuration should be applied on CE in order to fix this issue? 

A. jp prefix-list ROUTES_TO_SP seq 1 permit 10.1.1.64/28 

B. router bgp 65000 no network 10.1.1.64 mask 255.255.255.240 network 10.1.1.128 mask 255.255.255.128 

C. ip prefix-list ROUTES_TO_SP permit 10.1.1.64/28 

D. router bgp 65000 no network 10.1.1.64 mask 255.255.255.240 network 10.1.1.0 mask 255.255.255.0

Q2. Refer to the exhibit. 

OSPF is already running with the default OSPF parameters. R1 has added a new subnet (loopback 11). What will occur in regards to SPT computing on R2 router? 

A. Adding ispf command on R2 router, the entire SPT will be computed on R2 router. 

B. Because 10.11.11.11/32 prefix information will be in a LSA type 3 on R2 router's OSPF database, R2 router will run partial SPF computation. 

C. Adding ispf command on R2 router, R2 router will recompute only the affected part of tree. 

D. Because 10.11.11.11/32 prefix will be a LSA type 1 on R2 router's OSPF database. R2 router will always run a full SPF computation, even though an OSPF optimization is applied on R2 router.

Q3. Refer to the exhibit. How will the redistributed routes on R1 from EIGRP into OSPF be installed in the R4 routing table? 

A. as a default route with an E2 route type 

B. as a default route with an IA route type 

C. as specific routes with an E2 route type 

D. as specific routes with an N2 route type 

E. as a default route with an N2 route type

A. The Service Provider omitted the command l2protocol-tunnel stp. 

B. The Service Provider omitted the command l2protocol-tunnel vtp. 

C. The Service Provider omitted the command vlan dot1q tag native. 

D. The Service Provider omitted the command spanning-tree bpdufilter enable.

Q5. Which two statements about forwarding equivalence class (FEC) are true? (Choose two) 

A. FEC might correspond to a destination IP subnet, but it might also correspond to any traffic class that the edge LSR considers significant. 

B. FEC is a group of IP packets that is forwarded over a different path, but with the same forwarding treatment. 

C. FEC is a group of IP packets that is forwarded over the same path, and with the same forwarding treatment. 

D. FEC is a group of IP packets that is forwarded over a different path, but with the different forwarding treatment. 

E. FEC is a group of IP packets that is forwarded over the same path, but with a different forwarding treatment.

Q7. Refer to the exhibit. A web server is connected to a switch via two Gigabit Ethernet links. These two links are bundled into a single logical link that provides the aggregate bandwidth of 2 Gbps. The support engineer notices that traffic from the Internet to the web server uses both Gigabit Ethernet links. However, traffic from the web server to the Internet uses only one link. 

Which CLI command on the exhibit causes this behavior? 

A. lacp port-priority 32768 in interface configuration mode 

B. channel-group 5 mode passive 

C. lacp port-priority 32768 in global configuration mode 

D. port-channel load-balance dst-mac

Q8. Refer to the exhibit. Customer XYZ Site 1 is not learning prefixes from Site 2. What is the issue? 

A. MPLS LSP is broken along the path. 

B. The route-policy is not implemented in router PE-2. 

C. The BGP local-as command should be used between PE-1 and CE-1. 

D. The route-distinguisher values must match in both sites. 

E. The BGP as-override command should be implemented between PE-1 and CE-1.

Q9. A Service Provider connects to a client site that has two CEs. These CEs have a backdoor link for backup. OSPF is used as the routing protocol in this environment. You want to ensure that client traffic prefers the service provider connections for routing instead of the secondary connection. Which option describes the default behavior and the action that accomplishes your goal? 

A. The routes to the Service Provider are not preferred, due to the increased OSPF cost through the service provider network. Ensure that the cost on the links to the service provider are lower than the secondary connection. 

B. The routes to the Service Provider are seen as external type 1 in the OSPF database. Configure a domain ID that is the same across all PEs, to ensure that customers see routes as intra-area. 

C. The routes to the Service Provider are seen as inter-area OSPF routes through the network. Configure a sham link to create a new intra-area path across the service provider network between the PE routers that service the client. 

D. The routes to the Service Provider are seen as equal and cause nondeterministic traffic patterns. Ensure that the secondary connection has a higher cost than the links to the service provider.
