HPE Aruba Certified Network Security Expert (ACNSX) — Question 48

A network has two AOS-CX switches connected to two different service providers. The administrator is concerned about bandwidth consumption on the service provider links and learned that the service providers were using the company as a transit AS.
Which feature should the administrator implement to prevent this situation?

Answer options

• A. Configure route maps and apply them to BGP
• B. Configure the two switches as route reflectors
• C. Configure a classifier policy to disable MED
• D. Configure bi-directional forwarding detection on both switches

Correct answer: A

Explanation

The correct answer is A because configuring route maps allows the administrator to control the advertisement of routes, thus preventing the company from being used as a transit AS. The other options do not address the issue of route advertisement control; route reflectors (B) manage BGP peer relationships, disabling MED (C) does not prevent transit behavior, and bi-directional forwarding detection (D) is related to link failure detection, not route management.
