CompTIA Server+ SK0-005 Practice Question

During a data-center refresh, your team is replacing hard-coded static IPv4 addresses with DHCP-assigned addresses for every Windows and Linux server. One three-node application cluster must still be reachable on its existing IP addresses so that firewall rules and reverse-lookup (PTR) records stay valid-even after the nodes are re-imaged from a template. Operations wants the solution managed entirely on the DHCP server so administrators never have to touch the network settings inside the guest OSs. Which DHCP configuration best meets these requirements?

  • Define an exclusion range that contains the cluster IPs, then manually configure those addresses inside the virtual machines.

  • Create a reservation that maps each node's MAC address to its current IP and set the NICs to request an address via DHCP.

  • Configure network switches to insert DHCP Option 82 information so the server returns the same IP on every renewal.

  • Enable DHCP failover in load-balancing mode so the lease database is synchronized between two servers.
