CompTIA CASP+ (CAS-004) — Question 633

A company has instituted a new policy in which all outbound traffic must go over TCP ports 80 and 443 for all its managed mobile devices. No other IP traffic is allowed to be initiated from a device. Which of the following should the organization consider implementing to ensure internet access continues without interruption?

Answer options

• A. CYOD
• B. MDM
• C. WPA3
• D. DoH

Correct answer: D

Explanation

Implementing DNS over HTTPS (DoH) helps ensure that DNS queries are encrypted and sent over HTTP/HTTPS, allowing the devices to resolve domain names securely while still adhering to the port restrictions of TCP 80 and 443. Options A (CYOD) and B (MDM) do not directly address the need for secure DNS resolution, while C (WPA3) is focused on wireless security rather than managing outbound traffic.
