CompTIA Network+ (N10-007) — Question 538

An organization has migrated the internal network from a static IP addressing scheme to use DHCP. After fully deploying the DHCP solution, users within the web deployment team are unable to access the web server that is hosted in the DMZ. After reviewing the logs, the network technician sees multiple deny entries from the internal network to the DMZ. Which of the following is the MOST likely cause?

Answer options

• A. The DNS entries are incorrect for the web development team.
• B. The server IP addresses in the DMZ have changed after migrating to DHCP.
• C. The OSPF configuration was not updated to route the new dynamic address spaces.
• D. The ACL does not accurately reflect current addresses for the web development team.

Correct answer: D

Explanation

The correct answer is D because the Access Control List (ACL) likely needs to be updated to allow access for the new dynamic IP addresses assigned to the web development team. Options A and B are less likely since incorrect DNS entries or server IP changes would not directly cause the deny logs from the ACL. Option C is also unlikely unless specifically routing issues were detected, but the ACL is the most probable cause for denied access.
