Zorluk: KolayCommon Ports and Protocols

Match each application layer protocol to its corresponding default port number and transport protocol specification.

  • HTTPSTCP Port 443
  • RDPTCP Port 3389
  • DNSUDP/TCP Port 53
  • IMAPTCP Port 143

Cevap

HTTPS matches TCP Port 443, RDP matches TCP Port 3389, DNS matches UDP/TCP Port 53, and IMAP matches TCP Port 143.
HTTPS maps directly to TCP Port 443 for secure web communication. RDP maps to TCP Port 3389 for remote desktop access. DNS maps to UDP/TCP Port 53 for hostname-to-IP resolution. IMAP maps to TCP Port 143 for mailbox management and message retrieval.

Adım Adım Çözüm

1
Identify the standard service port for secure web browsing (HTTPS).
HTTPS uses TCP port 443.
Encrypted web traffic using TLS/SSL communicates by default over TCP 443.
2
Identify the standard service port for Microsoft Remote Desktop Protocol (RDP).
RDP uses TCP port 3389.
Remote management sessions using RDP listen on TCP port 3389.
3
Identify the service port for domain name resolution services (DNS).
DNS uses UDP/TCP port 53.
DNS relies primarily on UDP port 53 for lightweight queries and TCP port 53 for zone transfers or responses over 512 bytes.
4
Identify the standard unencrypted port for email retrieval via IMAP.
IMAP uses TCP port 143.
Standard IMAP mail access operates over TCP port 143.
