A technician runs report and notices utilization on one of the application servers in a round-robin pool is much lower than the others. Which of the following services should be checked FIRST to…

While file services are part of a server's functionality, they are not directly responsible for how a server receives load-balanced traffic in a round-robin pool.

DHCP is responsible for assigning IP addresses and is unrelated to an already configured and operational application server's utilization in a load-balanced environment.

ARP resolves IP addresses to MAC addresses and is fundamental to network communication, but it is not the primary component to check when an application server in a load-balanced pool is underutilized.

When a server in a round-robin pool has much lower utilization, it indicates that its cluster services or the specific application services that manage its participation in the load-balanced group might be misconfigured or not running correctly, preventing it from receiving its share of requests.
