Which command would troubleshoot an authentication error reported by an iSCSI host?

• A. iSCSI security show
• B. iSCSI security generate
• C. iSCSI show authentication
• D. iSCSI security authentication

Answer: (A)

When an iSCSI host reports an authentication error, you want to verify the current authentication setup on the storage side. The iSCSI security show command reveals the active iSCSI security configuration, including whether CHAP authentication is enabled, which credentials are configured for the initiator and target, and the status of those authentication settings. This makes it the most useful starting point for diagnosing why the host is failing to authenticate, because you can confirm if the correct CHAP secrets are in place and if mutual CHAP is required or mismatched. If you need to fix an issue, you’d typically adjust or reconfigure the secrets or CHAP settings based on what you find here. The other options either perform actions like generating secrets or relate to configuring authentication rather than reporting the current state, so they’re not as helpful for diagnosing the root cause of the authentication error.
