Question 1

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 2

An engineer is designing the QoS strategy for Company XYZ. Based on initial analysis, a lot of scavenger type of traffic is traversing the network's 20Mb Internet link toward the service provider. The new design must use a QoS technique that limits scavenger traffic to 2 Mbps, which helps avoid oversubscription of the link during times of congestion. Which QoS technique can be used to facilitate this requirement?

Options :

A : class-based traffic policing

B : LLQ

C : CBWFQ

D : class-based traffic shaping

Answer: D

Question 3

You have created a network design that has two point-to-point Metro Ethernet circuits extending a single production VLAN between two data centers. Under normal circumstances, one circuit will carry traffic and spanning tree will block the other. If the company wants you to make use of both circuits to carry production traffic, which two technologies and features will you investigate to integrate into your network design? (Choose two.)

Options :

A : EtherChannel

B : MST

C : Multichassis EtherChannel

D : PVST+

Answer: A,C

Question 4

A very large enterprise customer is migrating from EIGRP to IS-IS. Which option is your main concern to avoid changes in the path packets take?

Options :

A : the areas sizes

B : the redistribution points

C : the bandwidth and metrics on thelinks

D : the number of prefixes

Answer: C

Question 5

Company XYZ runs OSPF in their network. A design engineer decides to implement hot-potato routing architecture. How can this implementation be achieved?

Options :

A : Enable iBGP and apply prepend to ensure all prefixes will have the same length of the AS path attribute value.

B : Redistribute the external prefixes onto OSPF and ensure the total metric calculation includes only the ext value and the value is the same in all ASBRs.

C : Enable OSPF load-balancing over unequal cost path.

D : Redistribute the external prefixes onto OSPF and ensure that the total metric calculation includes external internal values.
