Sample 400-007 Exam Questions

Here are a few examples of the types of questions you might encounter on the real exam:

Question 1: SD-WAN Design

Which of the following is a key benefit of integrating SD-WAN into a large enterprise design?

A) Increased hardware dependency

B) Lower latency through MPLS-only links 

C) Reduced WAN costs through transport independence

D) Centralized routing protocols

Correct Answer: C) Reduced WAN costs through transport independence

Explanation: SD-WAN allows enterprises to use multiple transport types (MPLS, broadband, LTE), reducing dependence on costly MPLS circuits.

Question 2: BGP Design

When designing a BGP policy for a dual-homed enterprise site, what is the best practice to ensure return path symmetry?

A) Disable AS-PATH prepending 

B) Use route filtering to suppress all prefixes 

C) Employ MED and local preference adjustments 

D) Advertise host routes

Correct Answer: C) Employ MED and local preference adjustments

Explanation: MED and local preference are commonly used to influence inbound and outbound traffic paths to ensure optimal return routing.

Question 3: Network Security Design

What design technique can prevent lateral movement in a data center environment?

A) Use of a flat VLAN topology 

B) Deployment of access lists at the WAN edge 

C) Implementation of micro-segmentation 

D) Redundant power supplies for switches

Correct Answer: C) Implementation of micro-segmentation

Explanation: Micro-segmentation limits east-west traffic, reducing the risk of lateral attacks inside a data center.
