Designing Cisco Enterprise Networks (ENSLD) Questions and Answers

Question 45

Refer to the exhibit. An engineer is planning an IPv4 to IPv6 migration solution for a customer. The routers in the network can support IPv4 and IPv6, except for the DWDM routers. The DWDM routers provide a Layer 2 link in which the routers peer directly with each other across a DWDM circuit. The circuit also provides connectivity between the mail servers. Which IPv6 migration technique must the engineer deploy?

Options:

dual-stack

6to4

ISATAP

6rd

Question 46

Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)

Options:

a new OSPF area for R1 and R2 connections,with R1 and R2as ABRs

a new OSPF area for R3 and R4 connections,with R5 and R6as ABRs

a new OSPF area for R3 and R4 connections,with R3 and R4as ABRs

a new OSPF area for R1, R2, R3, and R4 connections, with R1, R2, R3, and R4 as

ABRs

a new OSPF area for R1 and R2 connections, with R5 and R6 as ABRs

Question 47

Refer to the exhibit. An architect is designing a Layer 3 campus network The design must hide network instability, reduce network overhead, and conserve critical device memory Which route summarization solution must the architect select?

Options:

• The core layer must advertise a default route toward the aggregation layer

• The VLAN subnets must be summarized into 10 0 0 0.'16 at the aggregation layer and advertised to the core layer

• The core layer must advertise a default route toward the aggregation layer

• The VLAN subnets must be summarized into 10 0 0 0/16 at the access layer and advertised to the aggregation layer

• The aggregation layer must advertise a default route toward the access layer.

• The VLAN subnets must be summarized into 10 0.0 0/16 at the aggregation layer and advertised to the core layer

• The aggregation layer must advertise a default route toward the core layer

• The VLAN subnets must be summarized into 10 0 0 0.116 at the aggregation layer and advertised to the access layer

Question 48

An engineer must design a VPN solution for a company that has multiple branches connecting to a main office. What are two advantages of using DMVPN instead of IPsec tunnels to accomplish this task? (Choose

two.)

Options:

support for AES 256-bit encryption

greater scalability

support for anycast gateway

lower traffic overhead

dynamic spoke-to-spoke tunnels
