Mary is a system administrator in your organization. she has recently made changes to the dhcp configuration file, but the dhcp daemon does not seem to recognize the new changes. what should she do?

Restart the DHCP daemon

Explanation:

DHCP refers to Dynamic Host Configuration Protocol and is one of the most common protocols to provide quick and centralized IP address distribution. It is often used in organizations so that they can monitor how the IP addresses are being used. If the DHCP daemon does not seem to recognize the new changes then Mary, the system administrator, must restart the DHCP daemon. It is possible that the changes to the DHCP configuration file require the system need to be restarted for implementing the changes. Therefore, restarting the DHCP daemon will be a sensible step.

speed

explanation:

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.
