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.
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.

A technician tries installing different toners to fix a printer that is printing blank pages, but the issue persists.
Which of the following is most likely causing the issue?
- A . Printer drum
- B . Printer ink
- C . Environmental temperature
- D . Corrupted printer drivers
A
Explanation:
A printer drum is a component of a laser printer that transfers the toner to the paper. It is a cylindrical metal or plastic piece that is coated with a photosensitive material. The drum is charged by a laser beam, which creates an electrostatic image of the document to be printed. The toner then sticks to the charged areas of the drum, and the drum rolls over the paper, transferring the toner to the paper and creating the printout1.
If the printer drum is damaged, worn out, or dirty, it may not be able to transfer the toner properly, resulting in blank pages.
According to some web search results23, some signs that a printer drum needs to be replaced are:
• Faint, light, faded, or blank printed pages
• Streaks, spots, or lines on the printed pages
• Error messages indicating a drum problem
To fix this issue, the technician may need to clean or replace the printer drum. Some web search results12 provide instructions on how to perform a manual drum cleaning or replacement.
Printer ink is not a likely cause of the issue, since the user has already tried installing different toners and the issue persists. Toner is the powder used by laser printers, while ink is the liquid used by inkjet printers. They are not interchangeable4.
Environmental temperature is not a likely cause of the issue, since most printers can operate in a wide range of temperatures. However, extreme temperatures may affect the quality and performance of some printers. For example, high temperatures may cause ink to dry out or toner to clump, while low temperatures may cause ink to freeze or toner to become brittle.
Corrupted printer drivers are not a likely cause of the issue, since they would affect the communication between the printer and the computer, not the printing process itself. Corrupted printer drivers may cause errors, delays, or incorrect outputs, but not blank pages.
A technician is configuring a desktop computer, and the hard drive must be encrypted.
Which of the following will the technician need to verify is enabled to complete this configuration?
- A . ATX
- B . NIC
- C . TPM
- D . ARM
C
Explanation:
TPM stands for Trusted Platform Module, which is a hardware component that securely stores encryption keys and other sensitive data12. TPM can be used to enable hard drive encryption, which is a technology that encrypts the data stored on a hard drive using sophisticated mathematical functions34. Hard drive encryption protects the data from unauthorized access in case the hard drive is lost, stolen, or tampered with.
A technician is setting up three web servers foe a retail company that takes online orders for its products .
Which of the following network host services should the technician use to ensure the servers’ resources will be utilized efficiently?
- A . UTM appliance
- B . AAA server
- C . Spam gateway
- D . Load balancer
D
Explanation:
A load balancer is a network device or service that distributes incoming network traffic across multiple servers, based on various criteria, such as availability, capacity, performance, or location. A load balancer can ensure that the servers’ resources will be utilized efficiently, as well as improve reliability, scalability, and security. A load balancer can be hardware-based or software-based, or a combination of both .

A user reports that a PC occasionally fails to start. The user restarts the PC, but the performance is degrading. The technician hears a strange repetitive ticking noise coming from the PC.
Which of the following should the technician do first?
- A . Try to extract data
- B . Reseat the RAM modules
- C . Inspect the fan
- D . Check the CD tray
A
Explanation:
The ticking noise likely indicates a failing hard drive. The technician should attempt to extract data before the drive fails completely.
A customer reports that a computer is never able to reach more than a 100Mbps transfer data rate, even when using a Gigabit LAN card. While troubleshooting, the technician notices the network cable needs to be replaced.
Which of the following cable categories is limiting the transfer speed?
- A . Cat 5
- B . Cat 5e
- C . Cat 6
- D . Cat 6a
A
Explanation:
Cat 5 cable is limited to a maximum data transfer rate of 100Mbps, while Cat 5e, Cat 6, and Cat 6a cables support Gigabit Ethernet (1000Mbps) and higher speeds. Even though the LAN card is capable of Gigabit speeds, it cannot achieve that speed when using a Cat 5 cable. Upgrading to a Cat 5e or higher cable would allow the computer to achieve Gigabit speeds.

A company’s cloud server has recently become unresponsive due to overwhelming e-commerce traffic.
Which of the following cloud technologies could be dynamically assigned to mitigate this issue?
- A . High availability
- B . Shared resources
- C . Metered utilization
- D . Rapid elasticity
D
Explanation:
A technician needs to install RAM into a rackmount server that will be used as a VM host.
Which of the following would be BEST to install?
- A . SODIMM
- B . VRAM
- C . DDR4
- D . ECC
D
Explanation:
When installing RAM into a server that will be used as a VM host, it is recommended to install ECC (Error-Correcting Code) RAM to help prevent errors that can cause virtual machines to crash.

When installing RAM into a rackmount server that will be used as a VM host, it would be best to install ECC (Error Correcting Code) RAM which can detect and correct common types of data corruption.
A user takes a tablet to a technician because the cursor on it keeps drifting. The technician notices the screen does not appear to be damaged.
Which of the following is the MOST likely cause of the cursor issue?
- A . The screen is physically damaged.
- B . The screen rotation is incorrect.
- C . The touch-pen battery is depleted.
- D . The screen needs to be recalibrated.
D
Explanation:
The most likely cause of the cursor issue is that the screen needs to be recalibrated. This can happen when the tablet is used for a long time or when the tablet is dropped or bumped. Recalibrating the screen will help the tablet recognize the touch input more accurately12.
