Question 1

A user reports that their laptop's battery indicator shows 'plugged in, not charging.' The technician tests the AC adapter with a multimeter and verifies it outputs the correct voltage. The laptop is a standard model with a removable battery. Which of the following components is MOST likely faulty?

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

Accepted Answer

Battery. The battery indicator showing 'plugged in, not charging' with a verified good AC adapter strongly points to a faulty battery. Since the adapter outputs correct voltage, the laptop detects the external power source (hence 'plugged in') but the battery itself cannot accept a charge, often due to degraded cells or failed internal protection circuitry. A removable battery is a common failure point, especially in older or heavily used laptops.

Answer

DC power jack

Answer

Motherboard charging circuit

Answer

Power management IC

Question 2

A cloud provider offers a service where customers can provision virtual servers with varying amounts of CPU, RAM, and storage on-demand. Customers are billed only for the actual resources they consume each hour, with no upfront commitment. This cloud characteristic is known as:

Accepted Answer

Measured service. (Measured service) because the scenario describes a pay-per-use billing model where customers are charged based on actual resource consumption (CPU, RAM, storage) per hour, with no upfront commitment. Measured service is a core NIST-defined cloud characteristic that enables metering and billing for usage, typically using a pay-as-you-go model. This directly matches the description of being billed only for resources consumed each hour.

Answer

Resource pooling

Answer

Rapid elasticity

Answer

On-demand self-service

Question 3

A company hosts a critical e-commerce application in a public cloud. The application is deployed across two availability zones in the same region. The cloud provider automatically monitors the health of the application in each zone and, if one zone becomes unavailable, all traffic is directed to the healthy zone without requiring any manual intervention. This setup BEST demonstrates which cloud characteristic?

Accepted Answer

High availability. This setup demonstrates high availability because the application is designed to remain accessible despite the failure of an entire availability zone. The cloud provider's automatic health monitoring and traffic rerouting ensure that if one zone goes down, all traffic is seamlessly directed to the healthy zone without manual intervention, minimizing downtime. This aligns with the core goal of high availability: eliminating single points of failure to maintain service continuity.

Answer

Elasticity

Answer

Scalability

Answer

Resource pooling

Question 4

A company uses a cloud platform where users can provision virtual servers and storage through a web portal without any human interaction with the IT staff. This capability is an example of which cloud computing characteristic?

Accepted Answer

On-demand self-service. The scenario describes users provisioning virtual servers and storage through a web portal without any human interaction with IT staff. This directly aligns with the NIST definition of on-demand self-service, where a consumer can unilaterally provision computing capabilities as needed automatically without requiring human interaction with each service provider. The key phrase 'without any human interaction' is the hallmark of this characteristic.

Answer

Broad network access

Answer

Resource pooling

Answer

Measured service

Question 5

A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS). IaaS provides virtualized computing resources (e.g., virtual machines) over the internet, giving the company full control over the operating system, software stack, and configuration. This allows them to install the custom library specific to a Linux distribution and configure the web server as needed, while the cloud provider handles the underlying physical infrastructure, minimizing administrative overhead. SaaS, PaaS, and FaaS abstract away the underlying OS and runtime, preventing the installation of distribution-specific libraries or custom server configuration.

Answer

Software as a Service (SaaS)

Answer

Platform as a Service (PaaS)

Answer

Function as a Service (FaaS)

Question 6

A technician is troubleshooting a user's wired desktop that can access local network shares and printers but cannot reach any internet websites. The technician pings the default gateway successfully. Which of the following is the most likely cause of this issue?

Accepted Answer

DNS server configuration is incorrect or the DNS server is unreachable. The user can access local resources (shares, printers) and successfully ping the default gateway, which confirms that Layer 2/3 connectivity, IP addressing, and routing are functional. However, the inability to reach internet websites while local access works points to a name resolution failure. DNS translates domain names to IP addresses; if the DNS server configuration is incorrect or unreachable, the browser cannot resolve website names, even though the network path to the internet is intact.

Answer

IP address conflict with another device on the network

Answer

Faulty network interface card (NIC)

Answer

Incorrect subnet mask on the workstation

Question 7

A user's Android smartphone exhibits a strange charging behavior. When the phone is powered off and connected to the wall charger, it charges normally and the battery percentage increases. However, when the phone is powered on and plugged into the same charger, the device shows the charging icon, but the battery percentage steadily decreases over time, eventually causing the phone to shut down. The user has already tried different charging cables and adapters, and has performed a factory reset. Which component is MOST likely faulty?

Accepted Answer

Battery. The battery is most likely faulty because it can hold a charge when the phone is off (minimal current draw) but fails under the higher load of the powered-on system. A degraded battery's internal resistance increases, causing voltage sag under load, which the PMIC interprets as a low charge state, leading to a net discharge despite the charger being connected.

Answer

Charging port / USB connector

Answer

Power management integrated circuit (PMIC)

Answer

Operating system battery calibration

Question 8

A user reports that a laser printer is displaying a 'Paper Jam' error even though no paper is visibly jammed inside the printer. The technician has removed all paper trays and checked the fuser area, rollers, and output bin, but finds no crumpled or stuck paper. Which of the following is the MOST likely cause of this error?

Accepted Answer

A stuck paper jam sensor. A stuck paper jam sensor can cause a false 'Paper Jam' error because the sensor remains in the triggered position even when no paper is present. The printer's firmware interprets the sensor's state as a jam, halting operation. Since the technician has visually confirmed no paper in all common areas, the sensor itself is the most likely culprit.

Answer

A faulty fuser heating element

Answer

A worn transfer roller

Answer

Outdated printer firmware

Question 9

A technician builds a PC with a CPU that supports PCIe 4.0, a motherboard with PCIe 4.0-capable slots, and a PCIe 4.0 GPU. After installation, the GPU is running at PCIe 3.0 speeds according to GPU-Z. The technician has updated the motherboard BIOS to the latest version and installed the latest chipset drivers. Which of the following is the MOST likely cause of the GPU not running at PCIe 4.0?

Accepted Answer

A. The GPU is installed in a secondary PCIe slot that is limited to PCIe 3.0. The most likely cause is that the GPU is installed in a secondary PCIe slot that is limited to PCIe 3.0. Even though the motherboard supports PCIe 4.0, not all slots on the board are necessarily wired for PCIe 4.0; secondary slots often run at PCIe 3.0 or lower due to chipset lane limitations. Installing the GPU in the primary (top) x16 slot, which is directly connected to the CPU, would allow PCIe 4.0 speeds.

Answer

B. The GPU firmware (vBIOS) is outdated

Answer

C. The power supply unit does not provide enough wattage

Answer

D. The GPU is not fully seated in the PCIe slot

Question 10

A technician is replacing the battery in an Android smartphone. Which of the following is the MOST important step to prevent damage to the SIM card during the repair?

Accepted Answer

Remove the SIM card tray. The SIM card is a delicate component that can be easily damaged if the phone is opened without first removing it. By taking out the SIM card tray, you eliminate the risk of bending or scratching the SIM card when prying the battery or handling internal components. This step is critical because the SIM card sits on a flexible tray that can snap or warp under pressure, potentially rendering the card unusable.

Answer

Power off the phone

Answer

Use a plastic spudger to pry the battery

Answer

Disconnect the screen flex cable

Question 11

A healthcare organization must store electronic health records in a cloud environment that meets HIPAA compliance requirements. The organization wants to keep sensitive patient data on-premises servers while using cloud resources for less critical workloads and to handle peak demand. Which cloud deployment model would BEST meet these requirements?

Accepted Answer

Hybrid cloud. A hybrid cloud model combines on-premises infrastructure (private cloud) with public cloud resources, allowing the healthcare organization to keep sensitive patient data on-premises for HIPAA compliance while using the public cloud for less critical workloads and to handle peak demand. This architecture provides the necessary data sovereignty and security controls for protected health information (PHI) while offering scalability and cost efficiency for non-sensitive tasks.

Answer

Public cloud

Answer

Private cloud

Answer

Community cloud

Question 12

A user's iPhone 12 has no sound from the speaker during phone calls, but the earpiece works normally. The user has confirmed that the volume is turned up and the silent switch is not enabled. The technician has performed a restart and updated iOS to the latest version. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The speaker grille is blocked or the speaker is faulty. The iPhone 12 uses a separate earpiece speaker for phone calls and a bottom-firing speaker for media and speakerphone. Since the earpiece works but the main speaker has no sound during calls, the issue is isolated to the bottom speaker grille being blocked (e.g., by debris or case obstruction) or the speaker itself being faulty. Restarting and updating iOS rules out software glitches, making hardware blockage or failure the most likely cause.

Answer

The Lightning port is clogged

Answer

The SIM card is damaged

Answer

The screen is cracked

Question 13

Employees in a small office report that their wired network connections become extremely slow or drop every time the office microwave oven is used. The microwave is located in the breakroom, and the network cables for the cubicles run through the ceiling directly above the breakroom. The cables currently installed are unshielded twisted pair (UTP) Cat5e. The technician has confirmed the microwave is not physically damaging the cables and that the router and switch are not overheating. Which of the following solutions would MOST effectively resolve the intermittent network issues?

Accepted Answer

Replace the UTP Cat5e cables with STP Cat6a cables. The intermittent network slowdowns and drops are caused by electromagnetic interference (EMI) generated by the microwave oven, which radiates strongly in the 2.4 GHz range. UTP Cat5e cables lack shielding and are susceptible to this EMI, especially when running through the ceiling directly above the microwave. Replacing them with STP Cat6a cables provides foil or braided shielding that blocks EMI, preserving signal integrity and resolving the issue.

Answer

Upgrade the network switches to models that support QoS (Quality of Service)

Answer

Install ferrite chokes on both ends of each network cable

Answer

Replace the RJ45 wall jacks with shielded Cat6 jacks

Question 14

A company must run a sensitive financial application that requires the application to be hosted on physical servers that are not shared with any other customer. The workload is highly variable and may require large amounts of resources for a few hours at a time. The company wants to minimize costs by paying only for the resources consumed. Which of the following cloud deployment models BEST meets these requirements?

Accepted Answer

Public cloud with dedicated hosts. A public cloud with dedicated hosts meets the requirement for physical server isolation (no resource sharing with other customers) while allowing the company to pay only for the resources consumed. The dedicated host option ensures the sensitive application runs on a physical server dedicated solely to that customer, and the public cloud's pay-as-you-go model supports the highly variable workload without long-term commitments.

Answer

Private cloud

Answer

Hybrid cloud

Answer

Community cloud

Question 15

A network technician is troubleshooting inter-VLAN routing. Clients on VLAN 10 (192.168.10.0/24) cannot communicate with servers on VLAN 20 (192.168.20.0/24). The router has subinterfaces configured for both VLANs and an ACL that permits all traffic between them. The router connects to a Layer 2 switch via a single cable. The switch port connecting to the router is configured as an access port in VLAN 10. Which of the following is the MOST likely cause of the communication failure?

Accepted Answer

The switch port connecting to the router is configured as an access port instead of a trunk. The router connects to the switch via a single cable, and the switch port is configured as an access port in VLAN 10. For inter-VLAN routing using router-on-a-stick, the switch port must be a trunk port that carries multiple VLANs (802.1Q tagged). An access port can only carry untagged traffic for a single VLAN, so frames from VLAN 20 cannot reach the router's subinterface, breaking communication.

Answer

The ACL is blocking traffic between VLAN 10 and VLAN 20

Answer

The router's subinterface for VLAN 20 has an incorrect IP address

Answer

The switch is not configured with VLAN 20
