Zorluk: ZorNetworking Ports and Protocols

A tier-2 help desk technician is deploying a dedicated server management workstation inside a secure management zone. The technician needs to enable remote management capability so administrators can open full graphical user interface (GUI) sessions on target remote Windows Server hosts without installing third-party agent software. The network security team requires strict port filtering on the internal firewall separating administrative subnets. Which of the following default transport protocol and port combinations must be allowed inbound on the target Windows servers to support standard Remote Desktop Protocol (RDP) connections?

  1. TCP port 3389Cevap
  2. B
    TCP port 23
  3. C
    TCP port 80
  4. D
    UDP port 67

Cevap

TCP port 3389 is the standard port used by Microsoft Remote Desktop Protocol (RDP) to enable full GUI remote administration sessions.
The correct option specifying TCP port 3389 represents the standard, default port used by Microsoft's Remote Desktop Protocol (RDP). RDP allows administrators to securely log into and control remote Windows computers with full access to the target host's graphical user interface (GUI).

Adım Adım Çözüm

1
Identify the technical requirements from the scenario
The requirement calls for native Windows full graphical user interface (GUI) remote administration without third-party agents.
Recognizing that Windows native GUI remote access relies on Remote Desktop Protocol (RDP) isolates the target protocol.
2
Map Remote Desktop Protocol (RDP) to its default transport layer port
RDP uses TCP port 3389 as its standardized default port.
CompTIA A+ objectives specify default port assignments for standard network protocols.
3
Evaluate and rule out distractor ports
TCP 23 (Telnet) provides text-only unencrypted CLI access; TCP 80 (HTTP) serves web content; UDP 67 (DHCP) handles IP address leasing.
Distinguishing between management, web, and infrastructure protocols ensures correct firewall ACL rules.
