Difficulty: EasyTFTP and FTP Operations for System Images and Configuration Management

When comparing operational characteristics between TFTP and FTP for managing Cisco IOS device configurations and system images, which two statements accurately describe their key protocol differences? (Select two.)

  1. FTP requires session authentication using explicit user credentials, whereas standard TFTP transfers operate without user authentication.Answer
  2. TFTP uses connectionless UDP at the transport layer, whereas FTP uses connection-oriented TCP to guarantee packet delivery.Answer
  3. C
    TFTP utilizes TCP port 69 to manage flow control and sliding window mechanisms during file transfers.
  4. D
    FTP uses UDP ports 20 and 21 to establish lightweight, unauthenticated file transmission channels.

Answer

The statements highlighting that FTP requires session authentication whereas TFTP operates without authentication, and that TFTP uses connectionless UDP whereas FTP uses connection-oriented TCP, are correct.
FTP uses TCP as its transport protocol (ports 20 and 21) providing connection-oriented reliability and requires user authentication credentials. TFTP uses UDP (port 69) as a simple, unauthenticated file transfer protocol.

Step-by-Step Solution

1
Analyze transport layer protocol assignment for TFTP and FTP.
TFTP uses UDP port 69 as its transport protocol. FTP uses TCP port 21 for control connections and TCP port 20 for data connections.
Understanding transport protocol mappings determines reliability mechanics and port requirements.
2
Analyze authentication features for both file transfer protocols.
FTP supports and mandates user authentication (username/password), whereas TFTP is a simplified protocol without native user authentication capabilities.
Distinguishing authentication capabilities helps identify secure vs simple file transfer operations.
