A network analyst is reviewing security baseline configurations across enterprise infrastructure servers. Match each network protocol on the left with its corresponding default transport protocol, port number, and primary operational function on the right.
- LDAPSTCP 636: Secure directory service authentication and query operations
- SFTPTCP 22: Encrypted file transfer leveraging Secure Shell protocol
- SNMPUDP 161: Polling managed network devices for status and performance metrics
- RDPTCP 3389: Graphical remote desktop administration for Windows host systems
Cevap
LDAPS pairs with TCP 636 for secure directory services; SFTP pairs with TCP 22 for encrypted file transfers over SSH; SNMP pairs with UDP 161 for device polling; and RDP pairs with TCP 3389 for graphical remote desktop sessions.
Each network protocol correctly corresponds to its standard transport protocol, default port number, and administrative use case: LDAPS uses TCP 636 for secure directory services; SFTP uses TCP 22 for secure SSH file transfers; SNMP uses UDP 161 for device monitoring; and RDP uses TCP 3389 for graphical remote desktop connections.
