The security team has been asked to only enable host A (10.2.2.7) and host B (10.3.9.9) to the new isolated network segment (10.9.8.14) that provides access to legacy devices. Access from all other hosts should be blocked. Which of the following entries would need to be added on the firewall?

The correct answer allows only specific hosts to access the isolated network segment and explicitly denies all other traffic. The first two rules permit traffic from host A (10.2.2.7) and host B (10.3.9.9) to the destination network (10.9.8.14/32), which represents a single host. The final rule, "Deny Any Any," acts as an implicit deny-all, blocking any traffic not explicitly permitted by the preceding rules. This ensures that only the specified hosts can reach the legacy devices. Other options might incorrectly specify source or destination IP addresses, use incorrect subnet masks (e.g., /24 instead of /32 for a single host), or lack a final deny-all rule, which is crucial for enforcing the "only enable" requirement.
