Question 1

What are two considerations for using the public Internet for WAN connectivity? (Choose two.)

AEnd-to-end traffic is best effort.

BIt is inherently insecure, and additional encryption should be considered.

CEnd-to-end CoS and larger MTU are possible.

DIt is inherently secure and does not require additional encryption.

Answer : B, C

Question 2

You are designing a solution for a company with a central office with several branch locations geographically dispersed. You are given the following requirements:

--- provides a different bandwidth at each location,

--- has any-to-any connectivity,

--- offloads some network responsibility.

--- is inherently isolated.

--- has a simple network design.

Which statement satisfies these requirements?

AImplement WAN over the public Internet.

BImplement Layer 3 VPN services at each location

CImplement Layer 2 VPN point-to-point circuits from each location to the central office.

DImplement services on a mesh of dark fiber between each location

Answer : C

Question 3

Which two protocols will meet this requirement? (Choose two )

ASpanning Tree Protocol

BLink Aggregation Control Protocol

CMPLS fast reroute

DEthernet ring protection switching

Answer : A, D

Question 4

Which topology satisfies these design requirements?

Ahub-and-spoke Internet WAN

Bfull mesh SD-WAN

Cfull mesh MPLS VPN

Dhub-and-spoke SD-WAN

Answer : D
