A systems administrator is establishing remote management procedures for a branch office network that contains Linux-based router appliances and Windows 11 Pro client workstations. The administrator must enable secure command-line administration for the routers and allow helpdesk technicians to remotely control the workstation desktops via graphical sessions. Which TWO of the following configurations or protocols must be implemented to fulfill these requirements securely? (Select TWO.)
- Permit inbound TCP port 22 traffic through firewalls to enable secure SSH command-line sessions on Linux router appliances.Answer
- Permit inbound TCP port 3389 traffic through host firewalls to allow Remote Desktop Protocol (RDP) sessions on Windows 11 Pro workstations.Answer
- CPermit inbound TCP port 23 traffic to enable encrypted Telnet remote terminal access to network routers.
- DUpgrade client workstations to Windows 11 Enterprise because Windows 11 Pro only supports outgoing RDP connections and cannot host incoming sessions.
Answer
The administrator must permit inbound TCP port 22 traffic to enable secure SSH terminal access for the Linux router appliances and permit inbound TCP port 3389 traffic to allow RDP sessions on the Windows 11 Pro client workstations.
The solution requires encrypted CLI access for Linux network hardware and full graphical remote desktop access for Windows workstations. SSH on TCP port 22 fulfills the secure CLI requirement, and RDP on TCP port 3389 provides graphical remote desktop control on Windows 11 Pro systems.
