A technician is troubleshooting a computer that is not completing POST and gets stuck at the manufacturer logo screen. All internal, removable parts have been disconnected and only the minimum parts necessary to POST were reconnected. However, the symptoms remain the same. Which of the following should the technician try NEXT?
- A. Remove and test the power supply.
- B. Replace the motherboard.
- C. Change the CMOS battery.
- D. Test the RAM in different slots, one at a time.

Every computer has a CMOS battery and when you remove that battery, your computer will work almost the same as before. The only difference is you won't be able to save any settings in the BIOS, which includes the date and time. If your PC is not booting after removing CMOS, you need to make sure that you have your CPU and RAM connected because it's not possible for your system to boot without those.. Your motherboard and computer will be able to boot just fine even without a CMOS battery present. The only issue is all your BIOS settings will be reset and the time and date will be inaccurate. You will also be unable to save BIOS settings.

NEW QUESTION # 203
A technician is receiving reports that the entire office sporadically loses network connectivity throughout the day. The technician determines the root cause to be EMI. Which of the following cable mediums would be the MOST cost effective without sacrificing system performance?
- A. Multimode fiber
- B. Shielded Cat 6
- C. Coaxial
- D. Plenum Cat 5e
Answer: B
Explanation:
Explanation
In this situation, the MOST cost-effective cable medium that would not sacrifice system performance would be B. Shielded Cat 6. Electromagnetic interference (EMI) can disrupt network connectivity by interfering with the signals transmitted over network cables. Shielded Cat 6 cables are designed to provide protection against EMI by incorporating a layer of shielding material around the cable's conductors. This shielding helps to prevent EMI from interfering with the signals transmitted over the cable.
NEW QUESTION # 204
Which of the following network devices would an administrator use to distribute traffic evenly throughout multiple nodes?
- A. Switch
- B. Proxy server
- C. Firewall
- D. Bridge
- E. Load balancer
Answer: E
Explanation:
Explanation
A load balancer is a network device that distributes network or application traffic across multiple servers to ensure that no single server bears too much of the load. Load balancing helps to improve application availability, increase scalability, and optimize resource utilization.
A bridge is used to connect two different networks, often to divide a larger network into smaller segments. A proxy server is used to forward client requests to other servers, and can also be used to cache frequently requested data. A switch is used to connect multiple devices within a network and to control the flow of network traffic. A firewall is used to secure a network by controlling incoming and outgoing traffic based on defined security rules.

NEW QUESTION # 207
A user reports that printed receipts have black smudges over the entire image. The text is still present but is very dark and sometimes illegible. Which of the following are the MOST likely cause and solution for the printer issue?
- A. The printhead is too hot. Adjust the temperature down and retry printing.
- B. The blue ink cartridge was loaded with black ink. Put in the correct ink and clean the printhead.
- C. The ribbon is jammed and is rubbing on the paper. Clear the bad ribbon and feed it through properly.
- D. The printer is loaded with the wrong type of paper. Replace the receipt paper with carbon paper.
Answer: A
Explanation:
Receipts are printed via a thermal printer. Thermal printers work by heating a paper in specified areas in order to create an image. The specific component that does this is a thermal printhead. Since the image appears to have black smudges and is too dark, we know the thermal printhead is too hot since the capability of precise heating has diminished

- D. The UPS, as 115V is insufficient for the configuration and should be increased to 220V
Answer: A
NEW QUESTION # 211
A technician is troubleshooting a computer that has a loud system fan and randomly freezes and reboots.
Which of the following is the most likely cause of these issues?
- A. Failing hard drive
- B. Incompatible hardware
- C. Overheating processor
- D. Defective power supply
Answer: C
Explanation:
Explanation
An overheating processor is the most likely cause of a computer that has a loud system fan and randomly freezes and reboots. A processor generates heat when it performs calculations, and if the heat is not dissipated properly, it can damage the processor or cause it to malfunction. A loud system fan indicates that the fan is working harder to cool down the processor, but it may not be enough to prevent overheating. A computer that freezes and reboots randomly is a common symptom of an overheating processor, as the system tries to protect itself from further damage by shutting down or restarting.
The other options are not as likely to cause these issues. A failing hard drive may cause data loss, corruption, or slow performance, but it does not affect the system fan or the processor temperature. A defective power supply may cause the computer to shut down unexpectedly, but it does not cause the system fan to be loud or the processor to overheat. Incompatible hardware may cause the computer to fail to boot, display errors, or crash, but it does not cause the system fan to be loud or the processor to overheat.
To troubleshoot and resolve an overheating processor issue, the technician should check and clean the air vents, provide proper ventilation, apply thermal paste, replace the fan or the heat sink, or upgrade the processor if necessary. The technician should also update the BIOS and the device drivers, adjust the power settings, and monitor the system temperature using diagnostic tools.

NEW QUESTION # 214
A technician is setting up a video-editing workstation and the operating system is already installed on an internal M.2 drive.
The new workstation must meet the following requirements:
. Be able to edit files at the fastest speed
. Allow for disk failure without any downtime
Have 2TB of usable space
. Ensure the most robust fault tolerance
INSTRUCTIONS
Use the drop-down menus to select the appropriate RAID level, drive types, and drive sizes based on the requirements above. For each drive type that is selected, a corresponding drive size must also be selected.
Answer:
Explanation:
Explanation
Based on the requirements, the best option for the video-editing workstation is to use RAID 10 with four SATA SSDs of 1TB each. This configuration will meet the following requirements:
Be able to edit files at the fastest speed: RAID 10 combines the advantages of RAID 0 and RAID 1, which are striping and mirroring, respectively. Striping can increase the data transfer rate by using multiple disks in parallel, while mirroring can provide redundancy and reliability by duplicating the data on another set of disks. SATA SSDs are also faster than HDDs or SSHDs, as they use flash memory instead of spinning disks, and they can offer lower latency, higher IOPS, and less noise and heat.
Allow for disk failure without any downtime: RAID 10 can withstand up to two disk failures, as long as they are not in the same mirrored pair. If one disk fails, the data can be read from or written to the other disk in the same pair, without affecting the performance or availability of the array. The failed disk can be replaced and rebuilt without interrupting the operation of the workstation.
Have 2TB of usable space: RAID 10 uses half of the total disk capacity for mirroring, so the usable space is equal to the size of two disks. By using four SATA SSDs of 1TB each, the total disk capacity is
4TB, and the usable space is 2TB, which meets the requirement.
Ensure the most robust fault tolerance: RAID 10 offers the highest level of fault tolerance among the standard RAID levels, as it can survive multiple disk failures and provide fast recovery. RAID 10 also has a low overhead, as it does not use parity or checksums, which can slow down the write performance or increase the complexity of the array.
Therefore, the technician should select the following options from the drop-down menus:
RAID level: RAID 10
Drive type 1: SATA SSD
Drive size 1: 1TB
Drive type 2: SATA SSD
Drive size 2: 1TB
Drive type 3: SATA SSD
Drive size 3: 1TB
Drive type 4: SATA SSD
Drive size 4: 1TB
Drive type 5: SATA SSD
Drive size 5: 1TB
