NEW QUESTION # 461
A technician is troubleshooting a PC that has been experiencing random system crashes. The technician has already checked the hard drive and the RAM, and both were in good working order. Which of the following steps should the technician take next to troubleshoot the system crashes?
- A. Test the fan speed.
- B. Disable the USB ports
- C. Decrease the RAM timings.
- D. Replace the PSU
Answer: D
Explanation:
A PSU (power supply unit) is a component that converts the AC power from the wall outlet into DC power that the PC components can use. A faulty or failing PSU can cause random system crashes, as well as other problems such as noise, overheating, or no power at all. A PSU can fail due to various reasons, such as age, dust, power surges, or poor quality.
To troubleshoot a PSU, the technician can use a multimeter to measure the voltage output of the PSU connectors. The voltage should be within the acceptable range of the specifications. For example, the 12V rail should be between 11.4V and 12.6V. If the voltage is too low or too high, the PSU is likely defective and needs to be replaced.
Alternatively, the technician can try swapping the PSU with a known good one and see if the system crashes persist. If the system works fine with a different PSU, then the original PSU is the problem and should be replaced.
The other options are not likely to fix the random system crashes. Testing the fan speed may help to diagnose overheating issues, but it is not related to the PSU. Disabling the USB ports may help to eliminate potential conflicts with USB devices, but it is not related to the PSU. Decreasing the RAM timings may help to improve performance and stability, but it is not related to the PSU.

A user reports that a printer pulls multiple sheets of paper from the paper tray instead of a single sheet. Which of the following should a technician investigate to resolve this issue? (Select two).
- A. Duplexer
- B. Fuser
- C. Pickup roller
- D. Toner cartridge
- E. Tractor feed
- F. Separation pad
Answer: C,F
Explanation:
The correct answers are C. Pickup roller and D. Separation pad.
A pickup roller is a rubber wheel that grabs the paper from the paper tray and feeds it into the printer. A separation pad is a small piece of cork or rubber that prevents more than one sheet of paper from being fed at a time. If the pickup roller or the separation pad is worn out, dirty, or damaged, it can cause the printer to pull multiple sheets of paper instead of a single sheet. This can lead to paper jams, misprints, or wasted paper.
To resolve this issue, a technician should investigate the condition of the pickup roller and the separation pad and replace them if necessary. The technician should also clean the paper tray and make sure the paper is loaded correctly and not stuck together.
A toner cartridge is a component that contains the toner powder used to create the printout on a laser printer. A tractor feed is a mechanism that uses sprockets to move continuous paper through a dot matrix printer. A duplexer is a device that allows a printer to print on both sides of the paper automatically. A fuser is a part of a laser printer that melts the toner onto the paper using heat and pressure. None of these components are related to the issue of pulling multiple sheets of paper from the paper tray.

SIMULATION
A user reports poor performance on the application server.
INSTRUCTIONS
Click on Server 1 and Server 2 and review the information presented in each chart to determine which drives need to be replaced.
Select the appropriate replacement drive that should be used, for the least performance degradation to the server.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Answer:
Explanation:
See the detailed solution in explanation below
Explanation:
The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.
Recommended Replacement Drive:
To minimize performance degradation, the replacement drive should be:
SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).
Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.
In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.
A user reports poor performance on the
application server.

NEW QUESTION # 470
A customer is using a satellite internet connection that is experiencing slowness. A technician notices high latency while pinging, but the download test is performing perfectly with very good download speeds. Which of the following represents the NEXT action the technician should perform?
- A. Guide the customer on how to upgrade the internet plan with the provider in order to improve latency.
- B. Replace the modem because it is not working correctly based on the test result.
- C. Restart the modem and run an online internet connection and speed diagnostic tool.
- D. Explain to the customer this is not an issue; this situation is normal for this type of internet connection.
Answer: C
Explanation:
The technician should restart the modem and run an online internet connection and speed diagnostic tool1. High latency is a common issue with satellite internet connections, and it can cause slow internet speeds2. Restarting the modem can help to resolve the issue1. The technician should also run an online internet connection and speed diagnostic tool to check the connection and speed1. Guiding the customer on how to upgrade the internet plan with the provider in order to improve latency is not likely to be the correct option2.
High latency while pinging can indicate a problem with the modem or the connection between the modem and the satellite. Restarting the modem can often resolve connectivity issues. Running an online internet connection and speed diagnostic tool can help identify any other issues with the connection. Upgrading the internet plan may not resolve latency issues and may not be necessary if the download test is performing perfectly with very good download speeds. High latency is not normal for satellite internet connections, so replacing the modem based on this one test result is premature. References: CompTIA A+ Certification Exam:

NEW QUESTION # 473
Which of the following should the data center hardware technician implement to ensure maximum uptime for customers' virtual machines?
- A. Cloud storage backup
- B. AC voltage regulator
- C. Uninterruptible power supply
- D. Line conditioner
Answer: C
Explanation:
An uninterruptible power supply (UPS) can help ensure maximum uptime for customers' virtual machines by providing a backup power source in case of a power outage or other power-related issues. A line conditioner and AC voltage regulator are designed to stabilize the power supply, but do not provide backup power. Cloud storage backup is a way to backup data, but does not directly impact uptime.
NEW QUESTION # 474
A technician needs to assign an IP address to a Windows PC, but a network connection is unavailable. Which of the following tools would be best for the technician to use?
- A. APIPA
- B. DHCP
- C. DNS
- D. TFTP
Answer: A
Explanation:
Automatic Private IP Addressing (APIPA) allows a Windows PC to automatically assign itself an IP address in the range of 169.254.0.1 to 169.254.255.254 when it's unable to obtain an IP address from a DHCP server. This feature is particularly useful in situations where the PC cannot connect to the network or when DHCP services are unavailable. While APIPA addresses are not routable and thus not suited for large networks, they enable basic networking functionality for small ad-hoc or local networks.
