Question 1

In a routed access hierarchical campus design, the access-to-distribution Layer 2 uplink trunks are replaced with Layer 3 point-to-point routed links. Why is it recommended that VLANs are confined on a single access switch rather than span across multiple access switches?

Options :

A : to allow for better convergence time

B : to prevent the occurrence of Layer 2 loops

C : to prevent routing black holes

D : to allow for fault isolation

Answer: A

Question 2

A key to maintaining a highly available network is building in the appropriate redundancy to protect against failure. This redundancy is carefully balanced with the inherent complexity of redundant systems. Which design consideration is relevant for enterprise WAN use cases when it comes to resiliency?

Options :

A : Design in a way that expects outages and attacks on the network and its protected resources

B : The design approach should consider simple and centralized management aspect

C : Design in a way that it simplifies and improves ease of deployment

D : Design automation tools wherever it is appropriate for greater visibility

Answer: A

Question 3

Which option is best suited to maintain Layer 3 separation in a multitenant data center design?

Options :

A : VXLAN

B : VRF

C : VDC

D : VLAN

Answer: B

Question 4

Software-defined networking architecture is used for cost-effective, adaptable, and easily manageable applications. In which two software-defined networks is SDN commonly used? (Choose two.)

Options :

A : wide area network

B : mobile network

C : metro network

D : application network

E : control network

Answer: A,E

Question 5

Company ABC grew organically and now their single-area OSPF network has an unacceptably slow convergence time after a topology change. To address the slow convergence time, they want to introduce a multiarea OSPF design and implement address summarization at the area border routers.

What should be their main concern about this redesign?

Options :

A : More memory is needed across the routers on the network

B : Routing is suboptimal

C : Operations complexity is increased

D : SPF calculation takes longer

Answer: B
