Question 1

Your company experienced a number of network incidents that had a significant impact on business operations. Because a root cause cannot be identified, your CTO asks you to help the network management team implement the FCAPS framework. On which two areas would you provide guidance to the network management team? (Choose two.)
A) change management
B) accounting management
C) service level management
D) fault management

Accepted Answer

The FCAPS framework includes five areas: Fault, Configuration, Accounting, Performance, and Security management. Fault management (D) is crucial for identifying and resolving network issues, while Accounting management (B) helps in tracking network usage and resources.

Question 2

Your design client has requested that you ensure that the client devices are not dynamically configured with incorrect DNS information. When finalizing the network design, which security option must be configured on the switches?
A) IGMP snooping
B) DHCP snooping
C) root guard

Question 11

What are two functions of an NSSA in an OSPF network design? (Choose two.)
A) It overcomes issues with suboptimal routing when there are multiple exit points from the area.
B) It allows ASBRs to inject external routing information into the area.
C) An ASBR advertises Type 7 LSAs into the area.
D) An ABR advertises Type 7 LSAs into the area.
E) It uses opaque LSAs.

An NSSA allows ASBRs to inject external routing information into the area using Type 7 LSAs, which are then converted to Type 5 LSAs by the ABR when leaving the NSSA.

Question 12

When a multiprotocol environment is designed to have several routers redistribute among the routing domains, how can routing loops be avoided?
A) by using the AS-PATH attribute
B) by using route tags
C) by activating split horizon

Question 14

The network administrator of a branch office network has decided to deploy Unicast RPF at the access layer.

Which mode of Unicast RPF would you recommend as the lead network designer?
A) uRPF strict mode
B) uRPF loose mode
C) uRPF VRF mode
D) RPF feasible mode

Accepted Answer

Unicast RPF strict mode ensures that packets are received on the interface that the router would use to forward return traffic, thus guaranteeing that packets are assigned to the same interface subnet.
