Which option in the chrony configuration file changes the initial interval of polls to a NTP server in order to speed up the initial synchronization?
The correct answer is A. iburst. iburst is correct because it is a legitimate chrony/NTP directive that causes the client to send a burst of 4-8 packets to the server during initial contact (when it is unreachable or for the first poll), dramatically reducing the time needed to achieve initial clock…

Explanation
iburst is correct because it is a legitimate chrony/NTP directive that causes the client to send a burst of 4-8 packets to the server during initial contact (when it is unreachable or for the first poll), dramatically reducing the time needed to achieve initial clock synchronization. The remaining options are simply fabricated: quickstart, fast, fsync, and flood are not valid directives in the chrony configuration file (/etc/chrony.conf). Memory tip: Think of "iburst" as "initial burst" - it fires a burst of packets at the initial connection to the NTP server, like a quick handshake to get in sync fast.
