When the network stack translates an IP address (network address) to a MAC address (data link address) it sends a broadcast using ARP to all devices on the subnet asking who has the specified IP address. The device with that IP address will then respond with it's MAC address to the ARP message's source.
With this in mind the answer to your question would either be broadcast or ARP request depending on what you have been learning in class.
Complete Question:
A campus bookstore sells both types and in the last semester sold 56% laptops and 44% desktops. Reliability rates for the two types of machines are quite different, however. In the first year, 5% of desktops require service, while 15% of laptops have problems requiring service.
Given that a computer required service, what is the probability that it was a laptop?
Answer:
Probability = 0.084
Explanation:
Given
Laptops = 56%
Desktop = 44%
Service Required (Laptop) = 15%
Service Required (Desktop) = 5%
Required
Determine the probability that a selected computer is a laptop and it requires service.
The question tests our knowledge of probabilities using "and" condition.
What the question requires is that, we calculate the probability of selecting a LAPTOP that REQUIRES SERVICE
Note the capitalised words.
This will be calculated as follows:
Probability = P(Laptop) and P(Service Required (Laptop))
[Substitute values for P(Laptop) and P(Service Required (Laptop))]
Probability = 56% * 15%
[Convert to decimal]
Probability = 0.56 * 0.15
Probability = 0.084
Answer:
C. Escalate the problem to a server administrator to check for issues with the server.
Explanation:
Pinging is a tool or program that IT technicians and professional for testing if a particular host or server is reachable. Since after the support technician pinged the email server from various location and the LAN results in 0% packet loss, this means that the fault is not from the LAN, but that the host server or server administrator is unreachable or have issues. Thus, the next step of troubleshooting is to escalate the issue to the server administrator to check for issues with their server.
