QUESTION 91

A company plans to use BFD between its routers to detect a connectivity problem inside the switched network. An IPS is transparently installed between the switches. Which packets should the IPS forward for BFD to work under all circumstances?

 

A.

IP packets with broadcast IP source addresses

B.

IP packets with identical source and destination IP addresses

C.

fragmented packets with the do-not-fragment bit set

D.

IP packets with the multicast IP source address

E.

IP packets with the multicast IP destination address

F.

IP packets with the destination IP address 0.0.0.0

 

Correct Answer: B

 

 

QUESTION 92

A company plans to include Nonstop Forwarding and Bidirectional Forwarding Detection as a part of their network redundancy plan. In which two ways do NSF and BFD work together when different hardware platforms are compared? (Choose two.)

 

A.

During supervisor engine or routing engine failover, the NSF feature will always ensure that the BFD at the peer router will not trigger a link down independent of the used hardware platform.

B.

At some hardware platforms, BFD and NSF are not supported together. During supervisor engine or routing engine failover, the BFD at the peer router will trigger a link down.

C.

To ensure that BFD at the peer router will not trigger a link down during NSF, the BFD packets must be processed fast enough, and, during supervisor engine or routing engine failover, by processing the BFD independent from the supervisor engine or routing engine.

D.

Because BFD is always processed at the line cards (not at the supervisor engine or routing engine), a supervisor engine or routing engine failover will not affect the BFD peer router.

E.

Because BFD is always processed at the supervisor engine or routing engine, a supervisor engine or routing engine failover will always trigger a link down at the peer router.

 

Correct Answer: BC

 

 

 

QUESTION 93

Refer to the exhibit. A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. In which two of these ways can you design this solution? (Choose two.)

 

clip_image002

 

A.

Enable Y.1731 Connectivity Fault Management on the SP switches.

B.

E-LMI PDUs must be forwarded over VPLS.

C.

Cisco Discovery Protocol PDUs must be forwarded over the VPLS.

D.

Use upward maintenance endpoints on the SP switches.

E.

Enable IEEE 802.1ag Connectivity Fault Management on the SP switches.

 

Correct Answer: DE

 

 

QUESTION 94

You are the lead IP/MPLS network designer of a service provider called XYZ. You are leading a design discussion regarding IPv6 implementation in the XYZ MPLS network, using MPLS 6PE/6VPE techniques. Currently, XYZ provides IPv4 multicast services over an MPLS network by using MVPN, and would like to provide parallel IPv6 multicast services. Which three multicast solutions should be enabled? (Choose three.)

 

A.

native IPv6, only for multicast services

B.

MPLS 6PE/6VPE, because it provides IPv6 multicast support by default

C.

an overlay model using Layer 2 MPLS tunnels

D.

PIM-DM to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE

E.

MVPN for IPv6 multicast service

 

Correct Answer: ACE

 

 

QUESTION 95

When creating a design plan for IPv6 integration, you decide to use stateless encapsulation of IPv6 packets into IPv4 tunnels between subscriber CPEs and a border relay. Which deployment technique allows for this functionality?

 

A.

6rd

B.

Dual-Stack Lite

C.

4rd

D.

DSTM

 

Correct Answer: A

 

 

QUESTION 96

Refer to the exhibit. In this network design, where should summarization occur to provide the best summarization and optimal paths during a single-failure incident as well as during normal operation?

 

clip_image003

 

A.

a single identical summary for all the branch offices placed on routers 1A, 1B, 2A, and 2B

B.

two summaries on 1A and 1B, and two summaries on 2A and 2B

C.

a single identical summary on 3A and 3B

D.

a single summary on each aggregation device for the branches connected to them

 

Correct Answer: C

 

 

QUESTION 97

A network designer has provisioned a router to use IPsec to encrypt the traffic over a GRE tunnel going to a web server at a remote location. From the router, the network designer can ping the web server, although the users in the office comment that they are unable to reach it. (Note: The DF bit is not set.) Which aspect should be changed in the design of the virtual connection?

 

A.

IP addresses of the GRE tunnel endpoints

B.

IPsec configuration

C.

MTU size on the GRE tunnel

D.

encapsulation of the GRE tunnel

 

Correct Answer: C

QUESTION 98

Refer to the exhibit. You are developing a migration plan to enable IPv6 in your IPv4 network. Starting at R3 and assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the link from R3 to R2?

 

clip_image005

 

A.

Only R3 and R2 have IPv4 and IPv6 reachability.

B.

R2 receives an IPv6 default route from R3.

C.

Loopback reachability between all routers for IPv4 is lost.

D.

All routers except R2 are reachable through IPv4.

E.

R3 advertises the link from R3-R2 to R1, R4 and R5 only.

 

Correct Answer: C

 

 

QUESTION 99

Refer to the exhibit. The design is being proposed for use within the network. The CE devices are OSPF graceful restart-capable, and the core devices are OSPF graceful restart-aware. The WAN

advertisements received from BGP are redistributed into OSPF. A forwarding supervisor failure event takes place on CE A. During this event, how will the routes learned from the WAN be seen on the core devices?

 

clip_image007

A.

via CE A and CE B

B.

via CE A

C.

via CE B

D.

no WAN routes will be accessible

 

Correct Answer: C

 

 

QUESTION 100

Refer to the exhibit. What limitations exist in this design, given that the access layer devices are expected to steadily increase by two devices per week for the next year?

 

clip_image009

 

A.

scalability

B.

serviceability

C.

redundancy

D.

resiliency

 

Correct Answer: A
