SK0-004 · Question #638

A systems administrator is setting up a new SAN. Which of the following protocols should be used to access and manage the system?

The correct answer is D. SSH. SSH provides encrypted remote access for securely managing network infrastructure such as a SAN, protecting credentials and configuration commands in transit.

Why each option

SSH provides encrypted remote access for securely managing network infrastructure such as a SAN, protecting credentials and configuration commands in transit.

AWWN

WWN (World Wide Name) is a 64-bit identifier assigned to Fibre Channel host bus adapters and ports for device identification, not a management or access protocol.

BNTP

NTP (Network Time Protocol) synchronizes clocks across systems and has no role in accessing or managing a SAN.

CDNS

DNS resolves hostnames to IP addresses and provides no mechanism for managing or accessing a SAN device.

DSSHCorrect

SSH (Secure Shell) is the standard protocol for encrypted remote CLI access to storage systems, switches, and servers. SAN management interfaces typically expose an SSH-accessible CLI or management host, and SSH ensures that authentication credentials and administrative commands are protected from interception - a requirement when managing sensitive storage infrastructure.
