A. B. C. D.B.
To configure a standalone AP to use an NTP server at IP address 192.168.1.99, we can use the following command:
A. ntp server 192.168.1.99
Explanation:
The Network Time Protocol (NTP) is a protocol used for synchronizing the clocks of network devices. It allows devices to maintain consistent time, even if they are located in different time zones or regions.
The command "ntp server <ip-address>" is used to configure the NTP server on a device. In this case, the IP address of the NTP server is 192.168.1.99.
Option B, "sntp server 192.168.1.99," is incorrect because "sntp" is a simplified version of NTP, and may not have all of the features of NTP. In this case, we want to use the full NTP protocol.
Option C, "ntp broadcast client 192.168.1.99," is incorrect because this command configures the AP to act as an NTP broadcast client. This means that the AP would listen for NTP broadcasts from the specified IP address, but it would not query the NTP server directly. This is not what we want in this case, as we want the AP to query the NTP server directly.
Option D, "sntp broadcast client 192.168.1.99," is incorrect for the same reason as option C. We want the AP to use the full NTP protocol and query the NTP server directly, rather than listening for broadcasts.
Therefore, the correct answer is A. "ntp server 192.168.1.99."
