Zorluk: OrtaNetworking Ports and Protocols

A network technician is updating port-filtering documentation for an enterprise firewall. Match each network protocol on the left with its corresponding default transport port and primary function on the right.

  • SSH (Secure Shell)TCP Port 22 - Secure encrypted command-line session management
  • TelnetTCP Port 23 - Unencrypted plaintext remote terminal communication
  • POP3S (Post Office Protocol 3 Secure)TCP Port 995 - Encrypted mail retrieval over SSL/TLS
  • SLP (Service Location Protocol)TCP/UDP Port 427 - Automated network service and resource discovery

Cevap

SSH matches TCP Port 22 (secure encrypted command-line session management); Telnet matches TCP Port 23 (unencrypted plaintext remote terminal communication); POP3S matches TCP Port 995 (encrypted mail retrieval over SSL/TLS); SLP matches TCP/UDP Port 427 (automated network service and resource discovery).
Each protocol correctly pairs with its official well-known port assignment and functionality according to CompTIA A+ Core 1 networking specifications.

Adım Adım Çözüm

1
Differentiate between secure and unencrypted remote access management protocols.
SSH provides secure encrypted console access over TCP port 22, whereas Telnet provides legacy unencrypted console access over TCP port 23.
Security policies require replacing cleartext Telnet (port 23) with encrypted SSH (port 22).
2
Identify the designated secure port for post office mail retrieval.
Standard POP3 operates unencrypted on TCP port 110, while POP3S enforces SSL/TLS encryption over TCP port 995.
Secure email retrieval protocols use distinct high-numbered ports to establish TLS/SSL sessions.
3
Associate dynamic local network service discovery with its standard port.
Service Location Protocol (SLP) communicates using TCP/UDP port 427.
SLP allows network endpoints to announce and locate devices dynamically on port 427.
