Explanation:
Refer to the exhibit.
A network administrator configured NTP on a Cisco router to get synchronized time for system and logs from a unified time source The configuration did not work as desired.
Which service must be enabled to resolve the issue?
- A . Enter the service timestamps log datetime localtime global command.
- B . Enter the service timestamps log datetime synchronize global command.
- C . Enter the service timestamps log datetime console global command.
- D . Enter the service timestamps log datetime clock-period global command
A
Explanation:
If a router is configured to get the time from a Network Time Protocol (NTP) server, the times in the router’s log entries may be different from the time on the system clock if the [localtime] option is not in the service timestamps log command. To solve this issue, add the [localtime] option to the service timestamps log command. The times should now be synchronized between the system clock and the log message timestamps.
