MD-100 100: Network Configuration 3

Question 1

A Windows 10 user reports that websites load by IP address but not by hostname. Which service is most likely failing?

Accepted Answer

DNS

Answer

DNS translates hostnames to IP addresses; if it fails, names cannot be resolved even though IP connectivity works.

Question 2

Which command displays the current DNS cache on a Windows 10 machine?

Accepted Answer

ipconfig /displaydns

Answer

ipconfig /displaydns shows all currently cached DNS entries on the local machine.

Question 3

A Windows 10 PC cannot communicate with any device on the local network. The IP address is correct but the subnet mask is 255.255.255.255. What is the effect?

Accepted Answer

The PC treats every host as being on a different network, preventing local communication

Answer

A /32 subnet mask (255.255.255.255) means the device sees itself as the only host on its network, isolating it from all others.

Question 4

Which Windows 10 tool provides a graphical view of network adapter settings, including speed, duplex, and driver details?

Accepted Answer

Device Manager

Answer

Device Manager shows detailed hardware properties including driver version, speed, and duplex settings for network adapters.

Question 5

A Windows 10 PC is configured with DNS server 8.8.8.8. What does this indicate about the DNS configuration?

Accepted Answer

The PC is using Google's public DNS server

Answer

8.8.8.8 is Google's well-known public DNS resolver, often used to bypass ISP or corporate DNS issues.
