A technician observes slow startup times on a laptop. Which of the following is most likely causing the issue?
- A. BIOS
- B. NIC
- C. RAM

NEW QUESTION # 82
A user reported performance issues on a computer after a recent OS update A technician is confident that rolling back the system will resolve the issue. Which of the following steps should the technician take next?
- A. Verify full system functionality.
- B. Initiate the system restore
- C. Investigate any recent infrastructure changes.
- D. Document the findings.
Answer: B
Explanation:
C:Initiate the system restore:
If the technician is confident that rolling back the system to a previous restore point will resolve the issue, the next logical step is to initiate the System Restore process.
System Restore allows the system to revert to a state before the OS update, which can eliminate the performance issues caused by the update.
Incorrect Options:
A: Document the findings: Documentation is important but should occur after resolving the issue.
B: Investigate any recent infrastructure changes: This is unnecessary if the issue is already attributed to the OS update.
D: Verify full system functionality: This step should be performed after the System Restore is completed.
Key Takeaway: When confident that rolling back will resolve the issue, the technician should proceed with initiating a System Restore to revert the OS.

NEW QUESTION # 83
A customer reports that the output from their thermal receipt printer has vertical white lines. Which of the following would most likely resolve this issue?
- A. Installing a maintenance kit
- B. Using the correct paper type
- C. Cleaning the heating element
- D. Replacing the ink cartridge
Answer: C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Thermal printerscreate images using aheated print headon specially coated thermal paper. Vertical white lines indicate thatpart of the heating element is dirty or blocked, preventing heat transfer to the paper. Cleaning the print head (heating element) will restore full functionality.
* Option A:Thermal printers donot use ink or toner, so this is not applicable.
* Option B:Wrong paper could cause blank output, but consistent vertical lines point to the print head.
* Option C:Maintenance kits are typically for laser printers, not thermal printers.

- B. Discharge lamp
- C. Fuser
- D. Developer roller
Answer: C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Inlaser printers, thefuser unitis responsible formelting the toner onto the paperusing heat and pressure. If the toner rubs off easily, it's a clear sign thefuser is failing or not heating properly. Replacing the fuser will ensure the toner bonds correctly to the paper.
* Option B (Drum):Transfers the image, but doesn't fuse the toner.
* Option C (Developer roller):Applies toner to the drum - wouldn't cause toner to rub off.
* Option D (Discharge lamp):Prepares the drum for a new image; not related to toner adhesion.

NEW QUESTION # 87
A third-party contractor recently installed a new switch, router, and cabling for a small corporate office. After the installation, users started experiencing issues connecting to resources over the network.
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.
