Question
Which of the following are valid NFSv4 security types?
Options
- ARSA
- BSSL
- CSPKM
- DKerberos
- ELIPKEY
Explanation
NFSv4 supports security types like SPKM, Kerberos, and LIPKEY, which are GSS-API mechanisms providing enhanced authentication and integrity beyond traditional AUTH_SYS.
Common mistakes.
- A. RSA is an asymmetric encryption algorithm, not a named NFSv4 security type (like
sec=) itself, although it's used within other security protocols. - B. SSL (Secure Sockets Layer) is a protocol for securing network communications, but NFSv4 uses its own RPCSEC_GSS-based security mechanisms like Kerberos rather than directly implementing SSL as a security type.
