When viewing NTP statistics in NIOS CLI, you notice an entry has the asterisk symbol...

Comprehensive and Detailed In-Depth Explanation:NTP (Network Time Protocol) synchronization is critical for Grid operations, and NIOS CLI provides status via show ntp:

Output Format:Lists NTP servers with symbols:

*: The server the member is currently synchronized to (stratum and offset shown).

+: Candidate server (reachable but not primary).

-: Unreachable or rejected server.

Asterisk Meaning:Indicates the active sync source, ensuring time consistency across the Grid.

Options:

A:Unreachable servers get a “-” or no symbol, not “*”. Incorrect.

B:Matches NTP convention and NIOS behavior—synchronized server. Correct.

C:Offline servers don’t sync and lack “*”. Incorrect.

D:Disabled NTP would prevent stats display, not mark a server. Incorrect.

Practical Example:In an INE lab, you’d run show ntp, see “*pool.ntp.org,” and troubleshoot time drift if the asterisk shifts, testing Grid stability.References:Infoblox NIOS CLI Reference Guide – NTP Commands; INE Course Content: NIOS DDI Grid Troubleshooting.
