NEW QUESTION # 303
A technician is replacing a failed drive in a RAID 5 array Which of the following is the first step the technician should take before hot swapping the drive out of the array?
- A. Perform a full backup
- B. Shut down the array_
- C. Safely dispose of the failed drive.
- D. Document the replacement date.
Answer: A
Explanation:
The answer is D. Perform a full backup.
Before replacing a failed drive in a RAID 5 array, the technician should perform a full backup of the data on the array to ensure that no data is lost during the hot swapping process. Hot swapping is the process of replacing a drive without shutting down the system or the array, which allows for faster recovery and minimal downtime. However, hot swapping also involves some risks, such as accidentally removing the wrong drive, damaging the new drive, or encountering another drive failure during the rebuild process. Therefore, performing a full backup is a precautionary measure that can prevent data loss in case of any unexpected errors or complications.
The other options are not the first steps that the technician should take before hot swapping the drive.
Documenting the replacement date is a good practice, but it is not as important as backing up the data.
Shutting down the array is not necessary for hot swapping, and it may cause more disruption to the system or the users. Safely disposing of the failed drive is a step that should be done after replacing it, not before.

INSTRUCTIONS
Click on each PC and server to review outputs. From the remediation section on the right, select an issue and solution for each device.
Answer:
Explanation:
See the Explanation and detailed steps below.
Explanation:
Looking at the network configurations and outputs from both PCs and servers, here are the possible issues and solutions:
1. PC 1
* Issue: The IP address for PC1 is 192.168.1.1, which conflicts with Server 1 (which also uses
192.168.1.1).
* Solution: Change the IP address on PC1 to a unique one within the range, like 192.168.1.3.
2. PC 2
* Issue: PC 2 is configured with 192.168.1.2, which conflicts with Server 2 that has the same IP address.
* Solution: Update the IP address on PC 2 to something unique, like 192.168.1.4.
3. Server 1
* Issue: The IP address for Server 1 is 192.168.1.1, which conflicts with PC1.
* Solution: Since Server 1 and PC1 are using the same IP address, change one of them. For Server 1, you could change the IP address to 192.168.1.5.
4. Server 2
* Issue: Server 2 is using the IP address 192.168.1.2, which conflicts with PC2.
* Solution: Update Server 2 to use a different IP address, such as 192.168.1.6.
General Remediation:
The primary problem here is overlapping IP addresses, leading to connectivity issues. Each device on the network must have a unique IP address. After making these changes, ensure that all devices can communicate properly by testing the connection between devices and verifying they can access shared resources.
NEW QUESTION # 313
A customer is reporting that some of the keys at the bottom edge on a laptop are hard to press and the track pad buttons require significant force to click. The technician inspects the laptop and does not notice any cracks or other damage to the chassis or screen. Which of the following is the most likely cause of the issue?
- A. The customer dropped the laptop.
- B. An open bottle of rubbing alcohol fell onto the keyboard.
- C. The digitizer has failed.
- D. The battery is swollen.
Answer: D
Explanation:
A swollen battery is the most likely cause of the issue that the customer is reporting. A swollen battery is a battery that has expanded in size due to a chemical reaction, gas buildup, or overheating. A swollen battery can cause pressure on the laptop's chassis, keyboard, track pad, and other components, making them hard to press or click. A swollen battery can also pose a fire hazard and damage the laptop's performance and lifespan.
The other options are not as likely or relevant to the issue. Dropping the laptop may cause cracks or other visible damage to the chassis or screen, but the technician did not notice any. The digitizer is the part of the laptop that converts touch input into digital signals, and it has nothing to do with the keyboard or the track pad buttons. An open bottle of rubbing alcohol falling onto the keyboard may cause liquid damage, corrosion, or short circuits, but it would not affect the track pad buttons or the bottom edge of the keyboard.
To troubleshoot and resolve the issue, the technician should remove the battery from the laptop and inspect it for signs of swelling, such as bulging, deformation, or leakage. The technician should also check the laptop's chassis, keyboard, and track pad for any signs of damage or warping caused by the battery. The technician should then replace the swollen battery with a new one that is compatible with the laptop's model and specifications. The technician should also dispose of the swollen battery properly and safely, following the local regulations and guidelines.

A technician is troubleshooting a thermal receipt printer that will not print. Which of the following should the technician do first to restore functionality?
- A. Make sure the thermal head is heating up.
- B. Update the printer driver on the computer.
- C. Flip the paper roll orientation.
- D. Replace the thermal printhead.
Answer: A
Explanation:
In the case of a thermal receipt printer that will not print, the first step in troubleshooting should be to ensure that the thermal head is heating up. Thermal printers operate by applying heat to a special thermally sensitive paper, creating marks on the paper to form text and images. If the thermal head is not heating up, it cannot create these marks, leading to no print output. Verifying that the thermal head is operational can help isolate the issue, whether it's a hardware malfunction of the thermal head itself or another problem in the printer.
References:
* CompTIA A+ Core 1 (220-1101) Exam Objectives, specifically sections dealing with printer technologies and troubleshooting methods, which would include understanding the operational basics of different types of printers, including thermal receipt printers.
* Fundamental knowledge of how thermal printers function, emphasizing the critical role of the thermal head in the printing process and the need to ensure it's operational when troubleshooting printing issues.
