With a recent summer time change, system logs are showing activity that occurred to be an hour behind real time. Which action should be taken to resolve this issue?
A.
Manually adjust the time to the correct hour on all managed devices.
B.
Configure the system clock settings to use NTP with Daylight Savings checked.
C.
Configure the system clock settings to use NTP.
D.
Manually adjust the time to the correct hour on the Cisco FMC.
If there is no option to enable Daylight Savings Time in the FMC GUI, then configuring the system clock settings to use NTP (Option C) is indeed the correct action. This will ensure that the system time is synchronized with a reliable time source, keeping the logs accurate.
Tricky question. The fmc uses ntp with utc time however in platform settings there is a timezone field that uses an ntp object that does have the dst check box, if you created an ntp object for your local time zone.
I found this. My opinion, the answer would be C.

Note that the time displayed on most pages on the web interface is the local time, which is determined by using the time zone you specify in your local configuration. Further, the Firepower Management Center automatically adjusts its local time display for daylight saving time (DST), where appropriate. However, recurring tasks that span the transition dates from DST to standard time and back do not adjust for the transition. That is, if you create a task scheduled for 2:00 AM during standard time, it will run at 3:00 AM during DST. Similarly, if you create a task scheduled for 2:00 AM during DST, it will run at 1:00 AM during standard time.

Daylight Saving is not part of ntp config list:
Set the Time Zone and Daylight Saving Dates
Set the Date and Time Using an NTP Server
Set the Date and Time Manually
Configure Precision Time Protocol (ISA 3000)

This is a terrible question. I guess the correct answer is C, but we dont know what time-zone the mentioned NTP server is in, so we have no way of knowing if using NTP will display the correct time. By default UTC is being used for NTP, and UTC has no summer time, meaning a NTP server with default setup, will not solve any "summertime problem". However, if the NTP server used is correcting the received UTC time received from stratum servers, to the local timezone, then C is correct. Its a lot of presumptions though, which is why this question is terrible :/
This is correct. Found this under Objects -> Time Zone w/ the Daylight Savings Time and Allow overrides - checkboxes for the Time Zone object
