CompTIA Network+ (N10-008) — Question 17

A network technician is configuring a new firewall for a company with the necessary access requirements to be allowed through the firewall. Which of the following would normally be applied as the LAST rule in the firewall?

Answer options

• A. Secure SNMP
• B. Port security
• C. Implicit deny
• D. DHCP snooping

Correct answer: C

Explanation

The correct answer is C, Implicit deny, as it serves as a catch-all rule that denies any traffic not explicitly permitted by previous rules. The other options, such as Secure SNMP and Port security, are specific controls that are applied before the implicit deny rule to manage access and security but do not serve the same overarching purpose.
