QUESTION 71

Which mechanism should be added to a network design to identify unidirectional Spanning Tree Protocol failures through BPDU loss?

 

A.

UDLD

B.

loop guard

C.

BPDU guard?

D.

root guard

 

Correct Answer: B

 

 

 

QUESTION 72

Refer to the exhibit. Acme Corporation hired you as a network designer to upgrade their network so that it supports IPv4 and IPv6 multicast. Which two protocols are needed on the LAN switch? (Choose two.)

 

clip_image002

 

A.

PIM sparse mode

B.

IGMP snooping

C.

PIM snooping

D.

Source Specific Multicast

E.

MLD snooping

 

Correct Answer: BE

 

 

 

 

 

 

 

 

QUESTION 73

You are designing a Group Encrypted Transport virtual private network solution for an existing branch network. The existing network has the following characteristics:

 

clip_image00450 remote sites (with an additional 30 remote sites expected over the next 3 years)

clip_image004[1]Connectivity between all sites is via Multiprotocol Label Switching Layer 3 virtual private network service from a single provider

clip_image004[2]Open Shortest Path First is the routing protocol used between provider edge and customer edge routers

clip_image004[3]The customer edge routers will become group members performing the encryption between sites

 

Which additional routing protocol would you use for the overlay routing between the group members?

 

A.

Open Shortest Path First (with a different process ID)

B.

Enhanced Interior Gateway Routing Protocol

C.

No additional protocol is necessary.

D.

External Border Gateway Protocol

E.

Routing Information Protocol Version 2

F.

Next Hop Resolution Protocol

 

Correct Answer: C

 

 

QUESTION 74

Refer to the exhibit. How would you adjust the design to improve convergence on the network?

 

clip_image006

 

A.

Add an intra-POP link between routers 1A and 1B, and enable IP LFA FRR.

B.

Use an IP SLA between the end stations to detect path failures.

C.

Enable SSO-NSF on routers 1A and 1B.

D.

Use BGP to connect the sites over the WAN.

 

Correct Answer: A

QUESTION 75

Which technique can you use to detect forwarding path failures at a uniform rate, and reconvergence times will be consistent and predictable when your routers are in the same broadcast domain?

 

A.

Enable BFD on your routers.

B.

Configure your routers with IP-SLA to ping the peer router.

C.

Configure your routers with IP-SLA and track to ping the peer and switch to a default route if the pings fail.

D.

Tune your routing protocol timers.

 

Correct Answer: A

 

 

QUESTION 76

During a corporate merger, a network designer is asked for a solution that will provide connectivity between the two enterprise networks. The solution must have the ability to support video sessions so that the CEO can message merger activities to the employees. The designer decides to consider multicast as a transport with MSDP to provide redundancy. Which transport feature does the network designer need to apply to the interconnecting firewall to ensure that Source-Active messages between the MSDP peers can be sent in both enterprise networks?

 

A.

unicast over a UDP connection

B.

multicast over a UDP connection

C.

unicast over a TCP connection

D.

multicast over a TCP connection

 

Correct Answer: C

 

 

QUESTION 77

A service provider creates a network design that runs MPLS in its WAN backbone using OSPF as the IGP routing protocol. What would be two effects of additionally implementing MPLS-TE? (Choose two.)

 

A.

MPLS-TE is required to reroute traffic within less than 1 second in case of a link failure inside the backbone.

B.

MPLS-TE is required to route different MPLS QoS service classes through different paths.

C.

MPLS-TE and OSPF cannot be used together inside one MPLS network.

D.

MPLS-TE cannot use OSPF for the traffic path calculation.

E.

MPLS-TE is required to create backup paths independently from the IGP.

 

Correct Answer: BE

 

 

QUESTION 78

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 79

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 80

As part of a new network design, you are helping the Network Management Team to develop a proactive report to identify places in the network where problems may happen. The network management tool can poll the network devices only via SNMP GET operations. Which two threshold-crossing metrics should you include in this report? (Choose two.)

 

A.

packet loss

B.

CPU utilization

C.

heat dissipation

D.

IP reachability

E.

energy consumption

F.

link bandwidth utilization

 

Correct Answer: BF
