- A.
DHCP is not enabled.
- B.
The default gateway setting is not configured.
- C.
The subnet mask is incorrect.
- D.
The system is on a different subnet than the DNS servers.
Correct Answer
B. The default gateway setting is not configured.Explanation
The most likely reason the user is having problems accessing the Internet is because the default gateway setting is not configured. The default gateway is responsible for routing network traffic from the local network to external networks, such as the Internet. Without a configured default gateway, the user's system does not know where to send network traffic that is destined for external networks. This would result in the user being unable to access the Internet.Rate this question:

Correct Answer
C. Tracert to the IP address of the serverExplanation
To determine delays from a local machine to a remote server on the Internet, you would use the "tracert" command to trace the route taken by the network packets from the local machine to the remote server. This command provides information about each hop along the route, including the time it takes for the packets to reach each hop. By analyzing the time taken at each hop, you can identify any delays or bottlenecks in the network path between the local machine and the remote server.Rate this question:

Correct Answer(s)
A. Plug the workstation into a different port on the network hub.
B. Change the network card in the workstation.
C. Try a known working cable on the connection to see whether it works.Explanation
The link light flashing intermittently on the network card indicates a problem with the physical connection between the workstation and the network. To troubleshoot this issue, you can try plugging the workstation into a different port on the network hub to see if the problem lies with the port. Changing the network card in the workstation can also help determine if the issue is with the card itself. Additionally, trying a known working cable on the connection can help identify if the cable is faulty. Changing the IP address is not relevant to resolving the intermittent connectivity problem.Rate this question:

The webserver can be accessed successfully through another router ona different remote network. What is the problem with the firstrouter?
- A.
The router is possibly being attacked from the WAN side.
- B.
The router is detecting too many packet collisions.
- C.
The hub that the clients use is damaged.
- D.
The router is disconnected
Correct Answer
B. The router is detecting too many packet collisions.Explanation
The solid red LED on the Link light of the router indicates that there are too many packet collisions occurring.
