QUESTION 21

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 22

A network designer is redesigning an enterprise campus network to ensure that Ethernet switches proactively attempt to reconnect after a fiber cut. In the design, they will have to address areas where fiber cuts exist on campus from past troubleshooting, where a single fiber is disconnected in the fiber pair, leading to looping. Which feature could be implemented in the design to allow the Spanning Tree Protocol on the switches to be protected?

 

A.

loop guard

B.

UniDirectional Link Detection

C.

UniDirectional Link Detection aggressive mode

D.

root guard

 

Correct Answer: C

 

 

QUESTION 23

A network designer wants to improve a company network design due to multiple network crashes. Which technology would allow for the restore of a network connection without informing the Layer 3 protocol?

 

A.

Bidirectional Forwarding Detection

B.

automatic protection switching

C.

UniDirectional Link Detection

D.

Ethernet OAM

 

Correct Answer: B

 

 

QUESTION 24

Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario?

 

A.

ISATAP

B.

6to4

C.

DMVPN

D.

6vPE

E.

6PE

 

Correct Answer: C

 

 

QUESTION 25

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

 

clip_image002

 

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 26

You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers). The goal of the network design is to provide a complete CoS solution to all customers that purchase services such as dedicated internet access, MPLS L3VPN, and L2VPN (pseudowire). Service Provider XYZ has these design requirements:

 

clip_image004The network supports four service queues with equal treatment for delay, jitter, and packet loss.

clip_image004[1]Queues are numbered 0-3, where 0 is the default queue.

Three queues have one treatment.

clip_image004[2]One queue has either one or two treatments.

 

How would you design your solution to map the DSCP value properly so that the traffic is assigned to the respective queues in the Service Provider XYZ MPLS core network?

 

A.

Classify traffic according to DSCP value into appropriate P router queues.

B.

Map the appropriate DSCP value into the EXP field based on the number of queues in the MPLS P routers.

C.

Map the appropriate DSCP value into the EXP field based on the number of queues in the MPLS PE routers.

D.

Based on the DSCP value, traffic is mapped automatically into appropriate queues in the MPLS CE routers.

 

Correct Answer: C

QUESTION 27

In which two ways is a network design improved by the inclusion of IP Event Dampening? (Choose two.)

 

A.

reduces processing load

B.

provides sub-second convergence

C.

improves network stability

D.

prevents routing loops

E.

quickly detects network failures

 

Correct Answer: AC

 

 

QUESTION 28

You are designing a network for a branch office. In order to improve convergence time, you are required to use the BFD feature. Which four routing protocols can you use to facilitate this? (Choose four.)

 

A.

EIGRP

B.

IS-IS

C.

BGP

D.

static

E.

RIP

 

Correct Answer: ABCD

 

 

QUESTION 29

Your organization is working on a design solution for a new Internet-based remote access virtual private network that has 1000 remote sites. A network administrator recommends GETVPN as the model because the network of today uses DMVPN, which results in a lot of background NHRP control traffic. What is a potential problem with using GETVPN for this design solution?

 

A.

GETVPN would require a high level of background traffic to maintain its IPsec SAs.

B.

GETVPN is not scalable to a large number of remote sites.

C.

GETVPN and DMVPN will not interoperate.

D.

GETVPN key servers would be on public, hacker-reachable space and need higher security.

 

Correct Answer: D

 

 

QUESTION 30

You have been hired by Acme Corporation to evaluate their existing network and determine if the current network design is secure enough to prevent man-in-the-middle attacks. When evaluating the network, which switch security option should you investigate to ensure that authorized ARP responses take place according to known IP-to-MAC address mapping?

 

A.

ARP rate limiting

B.

DHCP snooping

C.

Dynamic ARP Inspections

D.

IP Source Guard

 

Correct Answer: C
