NEW QUESTION # 37
An administrator is responding to a network server outage. The administrator has logged in to the server to troubleshoot the outage. Which of the following is the first step the administrator should take when attempting to troubleshoot the issue?
- A. Document the results.
- B. Check the physical connections.
- C. Upgrade the server firmware.
- D. Analyze the error logs.
Answer: D
Explanation:
The correct answer is B. Analyze the error logs.
Error logs are files that record the events and errors that occur on a server or a network device. They can provide valuable information about the cause and the time of the outage, as well as any warnings or alerts that preceded it. Analyzing the error logs can help the administrator narrow down the possible sources of the problem and identify the best course of action to resolve it.
The first step in troubleshooting a network is to identify the problem1. As a part of this step, the administrator should gather information about the current state of the network using the network troubleshooting tools that are available1. One of these tools is the error log viewer, which can be accessed through the server's operating system or a network monitoring software. The administrator should look for any entries that indicate a failure, a crash, a timeout, or an exception in the error logs. The administrator should also note the date and time of the entries, as well as the severity and the frequency of the errors.
The other options are less likely to be the first step in troubleshooting, because:
* Documenting the results is an important step in troubleshooting, but it should be done after identifying and resolving the problem, not before. Documenting the results can help the administrator keep track of the actions taken, the changes made, and the outcomes achieved. It can also help prevent future problems by providing a reference for best practices and lessons learned1.
* Checking the physical connections is another important step in troubleshooting, but it should be done after analyzing the error logs, not before. Physical connections are the cables and ports that link the server to other devices on the network. They can affect the quality and stability of the network signal. If the error logs do not indicate any software or configuration issues, then checking the physical connections can help determine if there is any damage or interference in the hardware2.
* Upgrading the server firmware is a possible solution for some network problems, but it should not be done as a first step in troubleshooting, unless there is a clear indication that the firmware is outdated or corrupted. Firmware is a type of software that controls the basic functions of a hardware device. Upgrading the firmware can improve performance, security, and compatibility, but it can also introduce new bugs or conflicts with other software or hardware components. Therefore, upgrading the firmware should be done with caution and only after backing up data and settings3.

NEW QUESTION # 38
Which of the following network devices is needed to direct packets to networks outside of the LAN?
- A. Switch
- B. Bridge
- C. Router
- D. Hub
Answer: C
Explanation:
Explanation
A router is a network device that connects multiple networks together and directs data packets to their intended destinations. This includes directing packets to networks outside of the local area network (LAN). Routers use routing tables to determine the best path for data packets to travel.
Hubs and switches operate within a single LAN and are not capable of routing packets to external networks.
Bridges can connect two LANs together, but they do not have the intelligence to route packets to external networks.
Therefore, only routers are capable of directing packets to networks outside of the LAN.

The subnet mask is a value that defines which part of the IP address identifies the network and which part identifies the host or device on that network. The IP address is a unique identifier that allows the printer to communicate with other devices.
NEW QUESTION # 40
A user's desktop computer slows down after a few minutes of use, and the fans alternate between silent and very loud. Which of the following is MOST likely failing, therefore causing these symptoms?
- A. Power supply
- B. Hard drive
- C. CPU fan
- D. Memory
Answer: C
Explanation:
Explanation
A CPU fan is a component that cools down the CPU, which is the main processor of the computer. If the CPU fan is failing, it can cause the computer to slow down and the fans to alternate between silent and very loud12.
This is because the CPU fan cannot maintain a consistent speed and airflow to keep the CPU at a safe temperature. When the CPU gets too hot, it throttles its performance to avoid overheating, which results in a slower computer. The other fans in the computer also try to compensate for the lack of cooling from the CPU fan by spinning faster and louder2
