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

Accepted Answer

Interference from the rugged case or other wireless signals is degrading the keyboard's connection. Bluetooth interference from other devices or physical obstructions (like a rugged case) can cause signal degradation, leading to missed keystrokes. The scanner may use a different Bluetooth profile or be less sensitive to interference. The correct answer identifies interference as the likely cause.

Answer

The keyboard's battery is low

Answer

The tablet's Bluetooth driver is outdated

Answer

The keyboard is not compatible with Android

Question 2

A user reports that their laptop's touchpad is not working after they spilt a small amount of coffee on the keyboard. The keyboard still works, but the touchpad cursor does not move. What is the most likely cause?

Accepted Answer

The liquid has damaged the touchpad or its ribbon cable. Coffee can seep into the touchpad connector or the touchpad itself, causing a short or corrosion. The keyboard working suggests the liquid did not reach the main board, but the touchpad is a separate component that is more exposed. The correct answer is liquid damage to the touchpad.

Answer

The touchpad driver has been corrupted by the liquid

Answer

The touchpad has been disabled in the BIOS due to a safety feature

Answer

The laptop's operating system has detected the liquid and disabled input devices

Question 3

A customer reports that their Android smartphone's screen remains black when they press the power button, but the device vibrates when receiving calls. They have already tried a force restart by holding Power+Volume Down for 15 seconds. What should you do next to isolate the issue?

Accepted Answer

Connect the phone to a known-good external monitor via USB-C to test video output.. This scenario points to a display or backlight failure, not a total system crash. The device is operational (vibrates), so the problem is likely with the LCD, backlight, or display cable. Testing with an external display or checking for physical damage is the logical next step.

Answer

Replace the battery immediately.

Answer

Perform a factory reset from recovery mode.

Answer

Reinstall the operating system using a PC.

Question 4

A technician is deploying 20 new tablets for a hospital's nursing staff. After configuring Wi-Fi and email, they find that the tablets will not connect to the corporate 5 GHz wireless network, only to the 2.4 GHz network. All tablets are the same model. What is the most likely cause?

Accepted Answer

The tablets only support 802.11b/g/n on the 2.4 GHz band and lack 5 GHz hardware support.. This is a common deployment issue where the device's wireless radio supports 2.4 GHz but not 5 GHz, or the 5 GHz channel is not supported. Older or budget tablets may lack 5 GHz capability, or the corporate network may use a 5 GHz channel (e.g., DFS channels) that the tablet's radio cannot use. Checking the tablet's Wi-Fi specifications is the correct first step.

Answer

The 5 GHz SSID is hidden and requires manual entry.

Answer

The corporate 5 GHz network requires 802.1X authentication that is not configured on the tablets.

Answer

The tablets have a defective Wi-Fi antenna.

Question 5

A technician is troubleshooting a Lenovo ThinkPad that will not turn on. When the power button is pressed, the keyboard lights flash briefly, then nothing. The battery is known to be charged. After removing the battery and holding the power button for 30 seconds, the laptop still does not power on. What should the technician try next?

Accepted Answer

Connect the laptop to a known-good AC adapter and try to power on without the battery installed.. This is a classic symptom of residual charge in the capacitors preventing a proper boot. The 'remove battery and hold power button' step discharges the system. If that fails, the next step is to test with a known-good AC adapter, as the internal charging circuit may be faulty. If that also fails, the motherboard or power button may be defective.

Answer

Replace the CMOS battery.

Answer

Reseat the RAM modules.

Answer

Perform a hard reset by disconnecting the internal battery (if accessible) and holding the power button for 60 seconds.

Question 6

A technician is setting up a multifunction printer for a small business that wants to allow employees to print from their smartphones. The printer does not have Wi-Fi Direct, but it is connected to the company's wired network. Which solution would enable mobile printing?

Accepted Answer

Configure the printer to support AirPrint. This question tests knowledge of mobile printing solutions in a network environment. AirPrint is a built-in iOS feature that discovers printers on the same network via Bonjour. Google Cloud Print is deprecated, and Bluetooth or USB tethering are not suitable for a wired network.

Answer

Enable Bluetooth on the printer and pair it with each phone

Answer

Use a USB cable to connect each phone to the printer

Answer

Install Google Cloud Print on the printer

Question 7

A user reports that when they scan a document using the flatbed scanner on their multifunction printer, the resulting image has a blue tint. The same user says printing works fine. What is the most likely cause?

Accepted Answer

The scanner lamp is failing. This question tests troubleshooting of scanner-specific issues. A blue tint indicates a problem with the scanner's color calibration or sensor, not the printer's output. The print quality is fine, so the issue is isolated to the scanning subsystem.

Answer

The toner cartridge is low on cyan

Answer

The document is placed upside down

Answer

The printer driver is corrupted

Question 8

A user reports that their USB 3.0 external hard drive is transferring data at very slow speeds, around 30 MB/s, when connected to a front-panel USB port. The same drive works at expected speeds (over 100 MB/s) on a rear USB port. Which connector-related issue is most likely?

Accepted Answer

The front-panel USB port is only USB 2.0, limiting speed.. Front-panel USB ports are often connected via internal headers that may only support USB 2.0 speeds, especially in older cases. This tests understanding that USB 3.0 requires a blue port and proper internal cabling for full speed.

Answer

The USB cable is damaged and needs replacement.

Answer

The external hard drive is not compatible with USB 3.0.

Answer

The front-panel USB port is not receiving enough power.

Question 9

A technician is installing a new graphics card in a desktop PC. The card requires two 8-pin PCIe power connectors, but the power supply only has one 8-pin and one 6-pin connector. What is the best solution to power the card?

Accepted Answer

Use a 6+2 pin PCIe power cable on the 6-pin connector.. A 6+2 pin PCIe power cable can be used to convert the 6-pin connector into an 8-pin by attaching the additional 2 pins. This tests understanding of modular power supply cables and PCIe power connector compatibility.

Answer

Use a Molex to 8-pin adapter on one of the connectors.

Answer

Plug the 6-pin connector into the 8-pin slot; it will work with reduced power.

Answer

Replace the power supply with one that has two 8-pin connectors.

Question 10

A user reports that their laptop's built-in webcam is not working in any application. The device manager shows the camera with a yellow exclamation mark. The technician has already updated the driver to the latest version, but the issue persists. What should the technician do next?

Accepted Answer

Check the laptop's physical privacy shutter or function key (e.g., Fn+F10) that may disable the camera.. A yellow exclamation mark in Device Manager indicates a driver problem, but since updating the driver did not help, the issue may be a hardware conflict or a disabled device. The next step is to check if the webcam is physically disabled via a function key (e.g., Fn+F10) or a privacy shutter. Many laptops have a hardware switch or a keyboard shortcut to disable the camera for privacy.

Answer

Uninstall the webcam driver from Device Manager and restart the laptop to let Windows reinstall it automatically.

Answer

Replace the webcam module.

Answer

Disable and re-enable the webcam in Device Manager.

Question 11

A company uses a cloud storage service for backup. The technician needs to ensure that if the primary cloud region goes down, the backups are still accessible from another geographic location. Which cloud characteristic should be configured?

Accepted Answer

High availability. High availability across regions is achieved through redundancy, such as replicating data to multiple geographic locations. This ensures that if one region fails, another can serve the data. Scalability, elasticity, and fault tolerance at a single site do not provide geographic redundancy.

Answer

Elasticity

Answer

Scalability

Answer

Fault tolerance

Question 12

A company's cloud-based virtual desktop infrastructure (VDI) is experiencing slow logins for users in a remote office. The network latency between the remote office and the cloud data center is 150 ms. What is the most effective solution to improve login performance?

Accepted Answer

Deploy a local VDI broker or caching server at the remote office. High latency significantly impacts VDI performance, especially during login when many resources are loaded. Deploying a local VDI broker or caching server at the remote office reduces round-trip time. Alternatively, using a CDN or WAN optimization can help, but a local broker is most effective for VDI.

Answer

Increase the bandwidth at the remote office

Answer

Upgrade the cloud VDI servers to faster CPUs

Answer

Switch to a different cloud provider

Question 13

A company uses a public cloud IaaS provider. The security team discovers that a virtual machine's data disk was accidentally deleted by an administrator. They need to recover the data from a snapshot taken 24 hours ago. The snapshot is stored in the same cloud region. What is the most efficient recovery method?

Accepted Answer

Create a new data disk from the snapshot and attach it to the VM. Most cloud IaaS providers allow creating a new volume from a snapshot, which can then be attached to the existing VM. This is faster than restoring the entire VM from a full image. The technician should create a new disk from the snapshot and attach it, then copy the data to the original disk if needed.

Answer

Restore the entire VM from the snapshot

Answer

Download the snapshot to an on-premises server and then upload it

Answer

Use the snapshot to create a new VM and then copy files via network

Question 14

A marketing department wants to access a shared calendar and document editing tools without installing any software on their local machines. Which cloud service model would best meet this requirement?

Accepted Answer

Software as a Service (SaaS). This question tests understanding of cloud service models. Software as a Service (SaaS) provides ready-to-use applications over the internet, eliminating the need for local installation. The scenario specifically requires access to calendar and document editing tools, which are typical SaaS offerings.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Function as a Service (FaaS)

Question 15

A company uses a PaaS provider to deploy a custom web application. After an update, the application fails to start. The developer checks the code and finds no errors. What is the most likely cause of the failure?

Accepted Answer

The PaaS provider updated the runtime environment, breaking compatibility. In PaaS, the provider manages the runtime environment, including dependencies and configuration. An update may have changed the underlying platform (e.g., runtime version, library) that the application relies on, causing incompatibility. The developer's code is fine, so the issue is environmental.

Answer

The developer's local machine has a different operating system

Answer

The application's database connection string is incorrect

Answer

The cloud provider's physical server has a hardware fault

Question 16

A technician is configuring a cloud-based backup solution for a client's critical data. The client requires that data be stored in a way that allows quick recovery of individual files from any point in the last 30 days. Which cloud storage model is most appropriate?

Accepted Answer

Object storage. Object storage is ideal for storing and retrieving individual files with versioning capabilities, enabling point-in-time recovery. It is scalable and commonly used for backup. Block storage is for raw volumes, and file storage is for shared file systems, but object storage offers the best granularity for file-level recovery over time.

Answer

Block storage

Answer

File storage

Answer

Cold storage

Question 17

A company uses a SaaS CRM application and wants to ensure that if the internet connection fails, employees can still access customer data. Which of the following is the best solution?

Accepted Answer

Configure the SaaS application to cache data locally on each user's device. SaaS applications are entirely dependent on internet connectivity. A local cached copy of the data can provide offline access. Other options like VPN or secondary internet are not practical for all employees, and a local server would require a different service model.

Answer

Set up a VPN to the cloud provider

Answer

Install a local server running the same CRM software

Answer

Purchase a secondary internet connection from a different provider

Question 18

A cloud architect is designing a solution where a company's web application automatically scales out to handle increased traffic and scales in during low demand. The application runs on multiple virtual machines. Which cloud characteristic is being utilized?

Accepted Answer

Rapid elasticity. Rapid elasticity is the ability to automatically scale resources up or down based on demand. This is a key characteristic of cloud computing. Other options like measured service or resource pooling are related but do not directly describe auto-scaling.

Answer

Resource pooling

Answer

Measured service

Answer

On-demand self-service

Question 19

A company is migrating its on-premises database to a cloud PaaS solution. The database currently contains sensitive customer information. Which of the following is the most important security consideration for the migration?

Accepted Answer

Configuring encryption for data at rest and in transit. When moving sensitive data to the cloud, encryption at rest and in transit is critical to protect against unauthorized access. While access controls and compliance are important, encryption is a fundamental requirement. The shared responsibility model means the provider secures the infrastructure, but the customer must secure the data.

Answer

Ensuring the PaaS provider has physical security at their data center

Answer

Setting up a VPN between the on-premises network and the cloud

Answer

Verifying that the provider uses a specific hypervisor

Question 20

A company is adopting a cloud-first strategy and wants to minimize vendor lock-in. They plan to use multiple cloud providers for different workloads. Which cloud deployment model does this describe?

Accepted Answer

Multi-cloud. A multi-cloud strategy involves using services from multiple cloud providers to avoid dependence on a single vendor. This is distinct from a hybrid cloud, which combines public and private clouds. Public cloud uses one provider, and community cloud is shared among organizations.

Answer

Public cloud

Answer

Hybrid cloud

Answer

Community cloud
