CompTIA Server+ SK0-005 Practice Question

An administrator is preparing to deploy 20 new blade servers that have no local storage. The plan is to boot each server over the network with PXE and pull a Windows Server image from an existing Windows Deployment Services (WDS) host on a different VLAN. During the first test, the firmware receives an IP address and PXE options from DHCP but immediately displays the message "TFTP download failed." A packet capture on the server VLAN shows DHCP traffic (UDP 67/68) and PXE discovery traffic (UDP 4011) reaching the WDS host, but no subsequent file-transfer packets. The firewall between the VLANs currently permits UDP 67, UDP 68, UDP 4011, TCP 135, and TCP 445 toward the WDS server. Which additional port and protocol pair must be allowed for the network installation to succeed?

  • TCP port 1433 (Microsoft SQL Server)

  • UDP port 514 (syslog)

  • UDP port 69 (Trivial File Transfer Protocol)

  • TCP port 3260 (iSCSI)
