A company installed WAPs and deployed new laptops and docking stations to all employees. The docking stations are connected via LAN cables. Users are now reporting degraded network service. The IT department has determined that the WAP mesh network is experiencing a higher than anticipated amount of traffic.
Which of the following would be the most efficient way to ensure the wireless network can support the expected number of wireless users?
- A . Replacing non-mobile users’ laptops with wired desktop systems
- B . Increasing the wireless network adapter metric
- C . Adding wireless repeaters throughout the building
- D . Upgrading the current mesh network to support the 802.11 n specification
D
Explanation:
When a WAP (Wireless Access Point) mesh network is experiencing a higher than anticipated amount of traffic, leading to degraded network service, upgrading the network to a more advanced wireless standard can help alleviate the problem. The 802.11n specification, also known as Wireless-N, offers significant improvements over earlier standards like 802.11b/g in terms of speed, range, and reliability. It allows for increased data throughput and better coverage, which can support a higher number of wireless users effectively.
Upgrading to 802.11n: This involves replacing existing WAPs with those that support the 802.11n standard or higher. The upgrade can result in improved network performance by accommodating more wireless connections with higher data rates, reducing congestion and improving overall network efficiency.
Replacing non-mobile users’ laptops with wired desktop systems (A) could reduce wireless traffic but may not be feasible or desirable for all users. Increasing the wireless network adapter metric (B) would affect route priority but not overall network capacity. Adding wireless repeaters (C) can extend the range but might also introduce additional latency and does not necessarily increase the network’s capacity to handle more users efficiently.
A computer is restarting automatically and displaying the following error message: "Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete).".
Which of the following should the technician do first to diagnose the issue?
- A . Check the system event logs.
- B . Verify the hardware driver versions.
- C . Install Windows updates.
- D . Perform a RAM diagnostic.
A
Explanation:
The first step is to check the system event logs using tools like Event Viewer. This will allow the technician to identify any critical errors or warnings that occurred before the restart. Based on these logs, further troubleshooting can be done. Verifying driver versions and performing diagnostics can follow once the root cause is identified.

Which of the following change management practices lists all the changes that are taking place for a project to ensure that no unexpected changes happen?
- A . Risk analysis
- B . Scope
- C . Rollback plan
- D . Review
B
Explanation:
In change management, the scope of a project lists all the changes that are taking place. The scope ensures that all team members understand the boundaries and extent of the project, helping to prevent unexpected changes.
Here’s a detailed explanation:
Scope: Defines the project’s boundaries and deliverables, including all the planned changes. It ensures that everyone involved understands what is included and excluded in the project, minimizing unexpected changes.
Risk analysis: Identifies potential risks and their impact but does not list the changes.
Rollback plan: Provides a strategy for reverting changes if something goes wrong but does not list changes.
Review: Involves evaluating changes but does not compile the list of changes.

Which of the following environmental controls is most important to maintain the safety of a data center?
- A . Temperature control
- B . Humidity control
- C . Fire suppression control
- D . Power management control
A
Explanation:
The most important environmental control to maintain the safety of a data center is Temperature control (A). Proper temperature control is crucial to prevent overheating, which can lead to hardware failure, reduced performance, and shortened equipment lifespan. Data centers house high-density computing equipment that generates significant amounts of heat, making effective temperature management essential for maintaining operational stability and reliability.

Which of the following is the FASTEST way for the technician to install Windows 10?
- A . Factory reset
- B . System Restore
- C . In-place upgrade
- D . Unattended installation
D
Explanation:
An unattended installation is the fastest way to install Windows 10 on a newly built computer. It uses an answer file that contains all the configuration settings and preferences for the installation, such as language, product key, partition size, etc. It does not require any user interaction or input during the installation process. Factory reset, System Restore and in-place upgrade are not methods of installing Windows 10 on a new computer, but ways of restoring or updating an existing Windows installation.
