Question 1

You work for a large enterprise network that spans many remote locations and uses EIGRP as its only routing protocol. Recently, the network grew too rapidly and it is having a lot of SIA problems, which impact the company business. In which two ways should you redesign the network to solve this problem? (Choose two.)

Options :

A : Eliminate the use of secondary networks.

B : Implement EIGRP Wide Metrics

C : Eliminate duplicate router IDs.

D : Implement route summarization.

E : Implement EIGRP Stub on remote locations.

Answer: A,D

Question 2

Refer to the exhibit.

Which impact of using three or more ABRs between the backbone area and area 1 is true?

Options :

A : In a large-scale network LSA replication by all ABRs can cause serious scalability issues

B : Multiple ABRs reduce the CPU processing on each A6R due to splitting prefix advertisement

C : In a large-scale network multiple ABRs can create microloops.

D : Prefixes from the non-backbone area are advertised by one ABR to the backbone

Answer: A

Question 3

A network engineer confirms that STP is enabled on all switches in the network. An edge switch is not sending or receiving configuration BPDUs, although it appears that everything is functioning correctly in the network. Which design explanation is true?

Options :

A : Bridge Assurance is enabled on the port

B : Storm control broadcast is enabled on the port

C : BPDU Guard is enabled on the port

D : REP is enabled on the port

Answer: D

Question 4

Which two reasons for implementing Cisco MPLS TE in a service provider MPLS backbone are valid? (Choose two.)

Options :

A : when Cisco MPLS TE is a prerequisite for implementing RSVP in the backbone

B : when Cisco MPLS TE is required to create backup paths independently from the IGP

C : when Cisco MPLS TE is required to route different MPLS QoS service classes through different paths

D : when Cisco MPLS TE is required to reroute traffic within less than 1 second in case of a link inside the backbone

E : when Cisco MPLS TE can detect and react to neighbor failures faster than IGPs can

Answer: A,B

Question 5

Which two statements describe the hierarchical LAN design model? (Choose two)

Options :

A : It is a well-understood architecture that provides scalability

B : It is the best design for modern data centers

C : It is the most optimal design but is highly complex

D : It provides a simplified design

E : Changes, upgrades, and new services can be introduced in a controlled and stagged manner

Answer: A,E
