Explanation/Reference: Explanation: The access group options are scanned in the following order, from least restrictive to most restrictive. However, if NTP matches a deny ACL rule in a configured peer, ACL processing stops and does not continue to the next access group option. * The peer keyword enables the device to receive time requests and NTP control queries and to synchronize itself to the servers specified in the access list. * The serve keyword enables the device to receivetime requests and NTP control queries from the servers specified in the access list but not to synchronize itself to the specified servers. * The serve-only keyword enables the device to receive only time requests from servers specified in the access list. * The query-only keyword enables the device to receive only NTP control queries from the servers specified in the access list.
