300-715 · Question #343

What is a difference between TACACS+ compared to RADIUS? (Choose two.)

The correct answer is B. TACACS+ uses a connection-oriented transport, and RADIUS uses a connectionless transport. D. TACACS+ offers multiple protocol support, and RADIUS supports only IP traffic. TACACS+ uses TCP for connection-oriented transport and offers broad protocol support for device administration, while RADIUS uses UDP for connectionless transport and primarily supports IP traffic for network access.

Question

What is a difference between TACACS+ compared to RADIUS? (Choose two.)

Options

  • ATACACS+ encrypts only the password, and RADIUS encrypts the entire packet payload.
  • BTACACS+ uses a connection-oriented transport, and RADIUS uses a connectionless transport.
  • CTACACS+ supports 802.1X network access control, and RADIUS supports only MAB.
  • DTACACS+ offers multiple protocol support, and RADIUS supports only IP traffic.

Why each option

TACACS+ uses TCP for connection-oriented transport and offers broad protocol support for device administration, while RADIUS uses UDP for connectionless transport and primarily supports IP traffic for network access.

ATACACS+ encrypts only the password, and RADIUS encrypts the entire packet payload.

RADIUS encrypts only the password by default, not the entire payload, while TACACS+ encrypts the entire packet body, making it more secure.

BTACACS+ uses a connection-oriented transport, and RADIUS uses a connectionless transport.Correct

TACACS+ utilizes TCP (Transmission Control Protocol) which is a connection-oriented protocol, ensuring reliable delivery, whereas RADIUS uses UDP (User Datagram Protocol) which is a connectionless protocol.

CTACACS+ supports 802.1X network access control, and RADIUS supports only MAB.

Both TACACS+ and RADIUS can support 802.1X network access control, and RADIUS also supports MAB (MAC Authentication Bypass).

DTACACS+ offers multiple protocol support, and RADIUS supports only IP traffic.Correct

TACACS+ is designed to support a wide range of network protocols for device administration, while RADIUS is primarily focused on network access authentication and authorization for IP-based traffic.
