Question 1

What are three requirements for a static IPv6-in-IPv4 tunnel? (Choose three.)

Options :

A : A static IPv6 address must be configured.

B : A dynamic IPv6 address must be configured.

C : Cisco Express Forwarding must be enabled.

D : Each tunnel endpoint must support IPv4 and IPv6.

E : A static IPv4 address must be configured.

F : A dynamic IPv4 address must be configured.

Answer: A,D

Question 2

Refer to the exhibit.

CE1 and CE2 cannot communicate through the service provider BGP peering is

established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core. What

step can be done to troubleshoot the issue?

Options :

A : Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.

B : Configure BGP between CE and PE routers.

C : Confirm that IS-IS is running with metric-style narrow.

D : Verify the MPLS LSPs

Answer: D

Question 3

Refer to the exhibit.

Refer to the exhibit. After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4. When the link from R2 is shut own as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the Branch office shows that traffic to HQ is still routed via R2. Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

Options :

A : Configure two OSPF processes on R2 and R3 and redistribute traffic between them.

B : Redistribute routes from BGP to OSPF as type El.

C : Use multiarea adjacency to extend Area 10 to the link between R2 and R3.

D : Create a virtual channel from R3 to R4.

Answer: B

Question 4

Refer to the exhibit.

The four routers in this network have formed adjacencies. Router R2 is an IS-IS level 1-2 router that connects to other areas, and the attach bit is set in the R2 level 1 LSP advertisements to R1. According to the network design, R2 should push level 2 routes from its routing table to the R1 routing table. However, R1 installed a default route in its routing table. Which action resolves this problem?

Options :

A :

Use The is-type level-1-2 backdoor command lo unset the attach bit on R1 and use a prefix List to filter prefixes from R2

B : Set the attach bit on R1and use a prefix list to filter prefixes from R2.

C :

Use the is-type level-1-2 backdoor command to unset the attach bit on R2 and configure a distribute-list to redistribute prefixes to R1

D : Configure R2 as a level 1 router and use a prefix list to filter prefixes to R1.

Answer: C

Question 5

Refer to the exhibit.

Refer to the exhibit. A network engineer configured three new PE routers to expand the network. The new routers run in the IS-IS routing protocol and reside in the data center in the same exchange as the existing routers. However, the network is now experiencing suboptimal routing. The Layer 2 configuration and VLANs are configured correctly to provide segregation between networks, but the Level 1 routes are not being converted to Level 2 routes. Which action resolves the issue?

Options :

A : On Router 1, redistribute the routes into IGP.

B : On Router 1, summarize internal routes between areas.

C : On Router 2, redistribute the routes into IGP.

D : On Router 2. summarize internal routes between areas
