NEW QUESTION # 28
A user regularly travels to multiple sites to take pictures with a mobile device and transfers those pictures to a computer via a removable SD card. Recently, the SD card was damaged and had to be replaced. Now, the user is unable to save pictures to the new SD card. Which of the following should the user verify first so pictures can be saved to the SD card?
- A. The card is correctly formatted.
- B. The card is a storage device.
- C. The card is not locked.
- D. The card is initialized.
Answer: C
Explanation:
When a user is unable to save pictures to a new SD card after replacing a damaged one, the first thing to check is whether the card is locked. Many SD cards have a physical switch on the side that can be toggled to a "locked" position, which prevents data from being written to the card.
Ensuring the switch is in the "unlocked" position allows the device to save data to the SD card.

NEW QUESTION # 35
Which of the following is the best way to protect the data of a virtual machine in the event of hardware failure?
- A. Redundant hardware
- B. UPS
- C. Cloud-based backup
- D. RAID
Answer: C
Explanation:
The best way to protect the data of a virtual machine in the event of hardware failure is to use a cloud-based backup solution. A cloud-based backup solution is a service that copies and stores the data of a virtual machine to a remote server or storage device over the internet. A cloud-based backup solution can offer several benefits, such as:
High availability and reliability: A cloud-based backup solution can ensure that the data of a virtual machine is always accessible and recoverable, even if the hardware that hosts the virtual machine fails or is damaged. A cloud-based backup solution can also provide redundancy and fault tolerance, by replicating the data across multiple locations or regions.
Scalability and flexibility: A cloud-based backup solution can adapt to the changing needs and demands of the virtual machine, by allowing the user to adjust the backup frequency, retention period, and storage capacity. A cloud-based backup solution can also support different types of backup, such as full, incremental, or differential, depending on the user's preferences and requirements.
Cost-effectiveness and simplicity: A cloud-based backup solution can reduce the cost and complexity of maintaining a backup infrastructure, by eliminating the need to purchase, install, or manage hardware, software, or licenses. A cloud-based backup solution can also automate and streamline the backup process, by providing easy-to-use tools and interfaces, such as web portals, APIs, or scripts.
Other options, such as redundant hardware, UPS, or RAID, may improve the performance or resilience of the hardware that hosts the virtual machine, but they do not provide a complete protection for the data of the virtual machine in the event of hardware failure. Redundant hardware is a technique that uses multiple components or devices to perform the same function, so that if one fails, another can take over. UPS (uninterruptible power supply) is a device that provides backup power to a system in case of a power outage or surge. RAID (redundant array of independent disks) is a technology that combines multiple disks into a logical unit, to improve the speed, capacity, or reliability of the storage. However, these options may not prevent data loss or corruption due to other causes, such as human error, malware, or natural disasters. Therefore, a cloud-based backup solution is the best way to protect the data of a virtual machine in the event of hardware failure.

In this scenario, the user's desktop computer is connected via an Ethernet cable and often drops the connection, while no other network users on the same floor are reporting issues. The administrator verified that all authentication systems are working as intended and the Ethernet cable was replaced.
NEW QUESTION # 40
A technician is trying to fix a computer that fails to boot even when all the RAM is removed. Which of the following should the technician do next to troubleshoot the issue?
- A. Inspect the motherboard for swollen capacitors.
- B. Check to see if the HDD power connectors are well seated
- C. Swap the power supply if it is inoperable.
- D. Replace the CMOS battery_
Answer: C
Explanation:
The next step that the technician should do to troubleshoot the issue is C. Swap the power supply if it is inoperable.
A power supply is a device that converts the alternating current (AC) from the wall outlet into direct current (DC) that the computer components can use. A power supply is essential for the computer to boot and function properly. A faulty or inadequate power supply can cause various issues, such as no power, no display, random shutdowns, or beeping sounds.
In this scenario, the technician is trying to fix a computer that fails to boot even when all the RAM is removed. RAM stands for Random Access Memory, and it is a type of memory that stores data and instructions for the processor to access and process. RAM is also essential for the computer to boot and function properly. A faulty or incompatible RAM can cause various issues, such as no boot, no display, blue screen, or beeping sounds.
One of the basic troubleshooting techniques for a computer that fails to boot is to remove all the RAM modules and try to boot with one module at a time in different slots. This can help to identify if the problem is caused by a bad RAM module or a bad RAM slot. If the computer still fails to boot even when all the RAM is removed, it means that the problem is not related to the RAM, but to another component.
The next step that the technician should do is to swap the power supply if it is inoperable. This means that the technician should test the power supply with a multimeter or a power supply tester, and replace it with a known good one if it is faulty or insufficient. This can help to determine if the problem is caused by a bad power supply or a bad motherboard.
The other options are not the next steps that the technician should do, because they are less likely or less effective. Inspecting the motherboard for swollen capacitors (option A) may be helpful if the problem is caused by a damaged or defective motherboard, but it requires opening the computer case and visually examining the motherboard components. Replacing the CMOS battery (option B) may be necessary if the problem is caused by a low or dead CMOS battery, but it usually affects only the BIOS settings and not the boot process. Checking to see if the HDD power connectors are well seated (option D) may be useful if the problem is caused by a loose or faulty HDD connection, but it usually affects only the data access and not the boot process.

NEW QUESTION # 41
A laptop is experiencing slow performance writing data. Which of the following is the best component for a technician to upgrade to fix the issue?
- A. TPM
- B. HDD
- C. RAM
- D. CPU
Answer: B
Explanation:
The best component for a technician to upgrade to fix the issue of slow performance writing data is B. HDD.
HDD stands for hard disk drive, which is a type of storage device that uses physical disks to store data. HDDs have moving parts that can slow down the read and write operations, especially when the data is fragmented or the disk is full12.
A better alternative to HDDs is SSDs, which stands for solid state drives. SSDs use flash memory and do not have any moving parts. SSDs can read and write data faster and use less power, which can improve the performance and battery life of the laptop13. Upgrading to an SSD can provide a significant improvement in performance2.
The other components are not as relevant or effective as upgrading the HDD. RAM stands for random access memory, which is a type of memory that stores temporary data for the CPU to process. RAM can affect the overall speed of the laptop, but it does not directly affect the writing performance of the storage device1. TPM stands for trusted platform module, which is a security chip that encrypts and protects data on the laptop. TPM does not affect the performance of the laptop, but rather its security1. CPU stands for central processing unit, which is the main processor of the laptop that executes instructions and calculations. CPU can affect the performance of the laptop, but it is not as easy or cost-effective to upgrade as the HDD1.

NEW QUESTION # 43
The motherboard on a user's company laptop was recently replaced. Now the user is unable to log in using the fingerprint reader. The fingerprint reader is working but it does not recognize the user's fingerprint. Which of the following should a technician perform FIRST to fix the issue?
- A. Restore the system to a previous recovery point
- B. Access the BIOS and clear the TPM
- C. Flash the newest BIOS firmware that is available
- D. Update the drivers and the fingerprint software
- E. Reinstall the fingerprint software
Answer: B
Explanation:
When the motherboard of a laptop is replaced, any data stored in the Trusted Platform Module (TPM) is lost. The TPM is a hardware module that securely stores data such as encryption keys, certificates, and, in this case, fingerprint data. If the fingerprint data was stored in the TPM, it would be lost with a motherboard replacement.
Clearing the TPM ensures it's ready for new data. Once the TPM is cleared, the user would likely need to re-enroll their fingerprint for the reader to recognize it again.
NEW QUESTION # 44
A technician is on site troubleshooting a customer's laptop. The technician needs to download a software update but the company's proxy is blocking updates. Which of the following would be the MOST appropriate action for the technician to take to get the update?
- A. Request a traffic exemption.
- B. Connect to a hotspot
- C. Update the Group Policy settings
- D. Change the DNS address to 1.1.1.1
Answer: A
Explanation:
Because the company's proxy is blocking the update for a reason, and changing the DNS address or connecting to a hotspot could expose the company's network to security risks.
A traffic exemption is a request to allow specific traffic to bypass the company's proxy. This can be done for a variety of reasons, such as when a technician needs to download a software update or access a website that is blocked by the proxy.
To request a traffic exemption, the technician should contact their IT department and explain why they need to download the update. The IT department will then review the request and determine if it is approved.
If the traffic exemption is approved, the technician will be able to download the update without any problems.
NEW QUESTION # 45
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. Change the CMOS battery.
- C. Test the RAM in different slots, one at a time.
- D. Replace the motherboard.
Answer: C
Explanation:
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 # 46
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
NEW QUESTION # 47
Which of the following technologies can allow multiple networks to traverse a switch?
- A. VRRP
- B. VLAN
- C. DHCP
- D. VPN
Answer: B
Explanation:
The technology that allows multiple networks to traverse a switch is VLAN (Virtual Local Area Network) which is a logical grouping of devices on the same network regardless of their physical location12.
Virtual Local Area Network (VLAN) technology can allow multiple networks to traverse a switch. A VLAN is a logical network created within a physical network that can separate traffic and allow multiple networks to coexist on the same physical network infrastructure. VRRP (Virtual Router Redundancy Protocol), VPN (Virtual Private Network), and DHCP (Dynamic Host Configuration Protocol) do not allow multiple networks to traverse a switch.

NEW QUESTION # 48
A technician installed four hard drives in a RAID 5 configuration. After creating the array, the technician is unable to copy files to the array within Windows. Which of the following should the technician do next?
- A. Check the hot spare status.
- B. Decrease the number of drives to three.
- C. Partition and format the volume.
- D. Rebuild the array.
Answer: C
Explanation:
After setting up a RAID 5 array, the next step is to make the storage space usable by the operating system. This involves partitioning the array to define how the storage space is organized and then formatting it with a file system that the operating system can understand, thus making it possible to copy files to the array. Decreasing the number of drives, rebuilding the array, or checking the hot spare status would not address the issue of the array not being ready to store files.
