Question 1

A user reports that their smartphone's Bluetooth will not enable. When the user taps the Bluetooth toggle in the Quick Settings panel, it briefly turns blue and then immediately turns gray. The phone did not get wet and was not dropped recently. Which of the following should the technician check FIRST?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Restart the smartphone. When Bluetooth fails to enable and the toggle immediately reverts, it often indicates a driver or firmware issue. The first step in troubleshooting should be to restart the device, as this clears temporary software glitches. If that does not work, checking for OS updates is the next step, as updates often include driver fixes. Replacing the battery is unlikely to help unless the battery is swollen (which would usually cause other symptoms). Resetting network settings is a more invasive step that should be done after trying a simple restart and updates.

Answer

Replace the battery

Answer

Check for operating system updates

Answer

Reset network settings

Question 2

A technician is setting up a new smartphone for a user. The user wants to be able to unlock the phone using their face. Which of the following biometric authentication methods should the technician configure?

Accepted Answer

Facial recognition. Facial recognition uses the front-facing camera to capture and analyze unique facial features, such as the distance between the eyes and the shape of the cheekbones, to authenticate the user. This is the correct biometric method for unlocking a smartphone with the user's face, as it directly matches the requirement.

Answer

Fingerprint scanner

Answer

Iris scanner

Answer

PIN code

Question 3

A laser printer produces pages with repeated marks at regular intervals. Replacing the toner cartridge does not resolve the issue. What component is the next likely cause?

Accepted Answer

Fuser or roller assembly. Repeated marks at regular intervals on laser printer output typically indicate a mechanical issue with a rotating component, such as a fuser roller or a transfer roller. Since replacing the toner cartridge did not resolve the problem, the next likely cause is a damaged or worn fuser roller assembly, which can leave marks corresponding to its circumference as it rotates.

Question 6

A database virtual machine in a private cloud is experiencing slow performance. The VM's virtual disk is stored on a network-attached storage (NAS) device accessed over a 1 GbE connection. The database requires very high input/output operations per second (IOPS) and low latency. Which of the following would provide the BEST improvement in storage performance?

Accepted Answer

Store the virtual disk on a local SSD within the host server.. Storing the virtual disk on a local SSD within the host server eliminates network latency and contention from the 1 GbE connection, providing the low latency and high IOPS required by the database. Local SSDs offer orders of magnitude lower latency than NAS over Ethernet, directly addressing the performance bottleneck.

Answer

Move the virtual disk to an object storage bucket.

Answer

Increase the allocated RAM of the VM.

Answer

Use thin provisioning to reduce the disk size.

Question 7

A user reports that their smartphone's battery life has significantly decreased after a recent OS update. The technician observes that location services and background app refresh are enabled. Which of the following should the technician do FIRST to address the issue?

Accepted Answer

Check the battery health status in the device settings. Before taking more invasive steps such as disabling all background processes or performing a factory reset, the technician should first check the battery health status in the device settings. Modern smartphones include a battery health feature that indicates the maximum capacity and whether the battery needs to be replaced. This helps determine if the battery is physically degraded, which could be the root cause of poor battery life, especially after an OS update that may have changed power management. If the battery health is good, then software settings like location services or background app refresh can be adjusted.

Answer

Calibrate the battery by fully draining it and then charging it to 100%

Answer

Disable all background app refresh settings

Answer

Perform a factory reset of the smartphone

Question 8

A company runs an internal web application on an on-premises virtual server that handles typical daily traffic. During seasonal sales, traffic spikes to ten times the normal volume. The company configures a public cloud service to automatically deploy additional virtual server instances when the on-premises server reaches a certain utilization threshold. These instances connect to the same database and load balancer, and they are terminated when traffic returns to normal. Which cloud architecture does this describe?

Accepted Answer

Cloud bursting. This scenario describes cloud bursting, a hybrid cloud model where an application runs primarily on-premises but can 'burst' into the public cloud during peak demand. This allows the company to handle traffic spikes without maintaining expensive idle capacity on-premises. Rapid elasticity is a characteristic of cloud computing, but cloud bursting is the specific architectural pattern that combines on-premises and public cloud resources.

Answer

Rapid elasticity

Answer

Resource pooling

Answer

High availability

Question 9

A company wants to ensure business continuity in the event of a primary data center failure. They replicate their critical virtual machines to a cloud provider's secondary region. In the secondary region, the VMs are stored as templates and are not running, but the cloud provider can instantiate them within minutes if needed. The company is charged only for the storage costs of the templates, not for compute resources. This approach BEST demonstrates which cloud computing characteristic?

Accepted Answer

Measured service. This scenario illustrates 'Measured service', one of the five essential cloud characteristics defined by NIST. Measured service means that cloud resources are metered and customers are billed only for what they consume. Here, the company only pays for storage (the templates) and not for idle compute, which would be the case if the VMs were running. While 'rapid elasticity' allows quick provisioning, it does not directly describe the billing model. 'High availability' implies redundant active resources, which is not the case here (VMs are offline). 'Resource pooling' refers to multi-tenant shared infrastructure.

Answer

High availability

Answer

Rapid elasticity

Answer

Resource pooling

Question 12

A user reports that a laser printer is printing vertical blank lines on every page. The toner cartridge is new and properly installed. Which of the following should the technician check FIRST?

Accepted Answer

Clean the corona wire. Vertical blank lines on laser printer output typically indicate a problem with the primary corona wire or charge roller that is not evenly charging the drum. Cleaning the corona wire often resolves this issue. The fuser, if faulty, would cause smudging or ghosting rather than blank lines. Pickup rollers affect paper feeding, not print quality. A paper jam would prevent printing altogether or cause a paper jam error message.

Answer

Replace the fuser assembly

Answer

Replace the pickup rollers

Answer

Check for a paper jam
