ECC (Error Correcting Code) memory is a type of memory that can detect and correct errors that may occur during data transmission or storage. ECC memory is essential for high-availability computing, as it prevents data corruption and system crashes2. References: ECC Memory

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.

802.11 ax is a wireless networking protocol that utilizes the 5.0GHz frequency and has the best speed and reception among the options given. 802.11 ax offers higher data rates, lower latency, increased capacity, and improved power efficiency than previous protocols. It is also known as Wi-Fi 6 or High Efficiency Wireless (HEW). 802.11a also uses the 5.0GHz frequency, but it is an older protocol that has lower speed and reception than 802.11 ax. 802.11b/g/n use the 2.4GHz frequency, which is more crowded and prone to interference than the 5.0GHz frequency. 802.11n can use both frequencies, but it is also slower and less efficient than 802.11 ax.

The first thing that the technician should do to diagnose the issue is A. Check the keyboard layout.

The keyboard layout is the arrangement of the keys and symbols on the keyboard, which can vary depending on the language, region, or standard. If the keyboard layout is not set correctly, it can cause the keys to produce different characters than expected. For example, if the keyboard layout is set to French, pressing the key for @ will produce à instead.

To check and change the keyboard layout, the technician can follow these steps:

•On Windows 10, click on the Start menu and select Settings.

•Click on Time & Language and then on Language.

•Under Preferred languages, click on the current language and then on Options.

•Under Keyboards, check if the keyboard layout matches the physical keyboard. If not, click on Add a keyboard and select the correct layout. Alternatively, click on Remove to delete any unwanted layouts.

•To switch between keyboard layouts, use the shortcut Windows key + Space bar.

Checking the keyboard layout can help identify and fix the issue quickly and easily, without requiring any hardware or software changes. Therefore, it is the best first step to diagnose the issue.
