Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 2

A user in a small office reports that their computer cannot access the internet. The technician runs ipconfig and sees the IP address is 169.254.15.22. The technician checks the network cable and sees link lights on the NIC and the wall jack. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The DHCP server is not responding or is unreachable. The IP address 169.254.15.22 is an Automatic Private IP Addressing (APIPA) address (169.254.0.0/16 range), which Windows assigns when a DHCP server cannot be reached. Since the link lights are active, the physical layer is functional, ruling out a cable fault. The most likely cause is that the DHCP server is not responding or is unreachable, preventing the client from obtaining a valid IP configuration.

Answer

The network cable is faulty

Answer

The user's computer has a duplicate IP address on the network

Answer

The subnet mask is incorrectly configured

Question 3

A user reports that their Android tablet's Wi-Fi connection frequently drops and reconnects. Other devices on the same network are stable. The technician has already forgotten the Wi-Fi network, rebooted the tablet, and confirmed the network password is correct. Which of the following is the BEST next step?

Accepted Answer

A. Update the tablet's firmware/OS. Since the issue is isolated to a single device and basic troubleshooting (forgetting the network, rebooting, verifying password) has not resolved it, the most likely cause is a software bug or driver incompatibility in the tablet's current firmware or OS. Updating the firmware/OS can patch known Wi-Fi connectivity bugs, such as those related to 802.11 power-save mode or DHCP lease renewal, which often manifest as intermittent disconnects.

Answer

B. Change the Wi-Fi channel on the router

Answer

C. Replace the tablet's Wi-Fi antenna

Answer

D. Factory reset the tablet

Question 4

A company hosts its e-commerce website on a public cloud platform. During the holiday shopping season, traffic increases dramatically. The cloud platform automatically adds more virtual server instances to handle the increased load and then removes them when traffic returns to normal. Which cloud computing characteristic does this scenario BEST describe?

Accepted Answer

Rapid elasticity. The scenario describes the cloud automatically scaling virtual server instances up and down in response to traffic spikes, which is the defining characteristic of rapid elasticity. This allows resources to be provisioned and released elastically, often automatically, to match demand at any given time.

Answer

On-demand self-service

Answer

Measured service

Answer

Resource pooling

Question 5

A user reports that their Android smartphone's battery drains very quickly, even when the phone is not in use. The user has already closed all background apps, and the battery statistics show that the 'Screen' is the top consumer at 35%, which seems normal. The technician notices that the phone's back feels warm near the top. Which component is MOST likely faulty?

Accepted Answer

A: Battery. Battery. A faulty battery can cause rapid discharge and generate excessive heat, even when the phone is idle and background apps are closed. The warmth near the top of the phone is a classic symptom of internal battery degradation or a shorted cell, leading to increased internal resistance and heat generation.

Answer

B: Charging port

Answer

C: Proximity sensor

Answer

D: NFC chip

Question 6

A user reports that their network printer shows 'Offline' in the print queue on their Windows computer. The printer is powered on and has a link light on its network port. Other users on the same network can print to the printer without issue. Which of the following should the technician do FIRST?

Accepted Answer

Set the printer back online in the printer settings. The user's printer shows 'Offline' in the print queue, but it is powered on, has a link light, and other users can print to it. This indicates the printer and network are functioning correctly; the issue is that the printer's status on the user's computer has been set to 'Offline' or 'Use Printer Offline' in the printer properties. The first step is to set the printer back online by right-clicking the printer in 'Devices and Printers' and unchecking 'Use Printer Offline' or selecting 'See what's printing' and clicking 'Printer' > 'Use Printer Online'.

Answer

Restart the print spooler service on the user's computer

Answer

Reinstall the printer driver on the user's computer

Answer

Power cycle the printer

Question 7

A company runs its e-commerce platform on a private cloud but expects a large traffic spike during a promotional event. They want to automatically add additional virtual servers from a public cloud provider during the peak and release them afterward. Which cloud computing characteristic best describes this capability?

Accepted Answer

Elasticity. Elasticity is the cloud computing characteristic that allows resources to be automatically scaled up or down based on demand. In this scenario, the company uses a hybrid cloud model where additional virtual servers from a public cloud provider are provisioned during a traffic spike and released afterward, which is the definition of elasticity. This contrasts with scalability, which is the ability to handle growth over time, as elasticity specifically addresses dynamic, automated scaling to match fluctuating workloads.

Answer

High availability

Answer

Fault tolerance

Answer

Resource pooling

Question 9

A user in a densely populated apartment building complains of frequent Wi-Fi disconnects and slow speeds on the 2.4 GHz band. A spectrum analysis shows many overlapping networks on channels 1, 6, and 11. The router supports both 2.4 GHz and 5 GHz. Which of the following is the BEST solution to improve the user's wireless experience?

Accepted Answer

A. Change the client device to use the 5 GHz band. The 2.4 GHz band is congested with overlapping networks on channels 1, 6, and 11, causing co-channel interference and contention. Moving the client device to the 5 GHz band provides access to many more non-overlapping channels (e.g., 36, 40, 44, 48) and typically less interference, resulting in fewer disconnects and higher throughput.

Answer

B. Change the wireless security from WPA2 to WPA3

Answer

C. Increase the router's transmit power to maximum

Answer

D. Change the network SSID to a unique name

Question 10

A company wants to move its email system to the cloud. The cloud vendor provides the email service, including server hardware, operating system, and software. The company only needs to manage user accounts and mailboxes. Which cloud service model is the vendor providing?

Accepted Answer

Software as a Service (SaaS). The vendor provides the entire email service, including server hardware, operating system, and software, while the company only manages user accounts and mailboxes. This matches the Software as a Service (SaaS) model, where the provider delivers a complete application over the internet, and the customer has no control over the underlying infrastructure or platform.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 11

A laser printer produces pages where the toner smudges easily when rubbed. The technician has already replaced the toner cartridge and the imaging drum with new OEM components. The fuser is heating to the correct temperature during operation. Which of the following printer components is MOST likely causing this issue?

Accepted Answer

Fuser roller. The fuser roller is responsible for melting toner into the paper fibers using heat and pressure. If the toner smudges easily despite the fuser heating to the correct temperature, the fuser roller's pressure mechanism or its release coating is likely worn or damaged, preventing proper fusing. Replacing the toner cartridge and imaging drum would not resolve a defective fuser roller.

Answer

Transfer roller

Answer

Laser scanner

Answer

Paper pickup rollers

Question 12

A network technician is setting up a small office with 15 workstations. The ISP provides a single public IPv4 address. The technician configures the router to assign private IP addresses (192.168.1.x) to the workstations via DHCP. Which technology allows all 15 workstations to share the single public IP address to access the internet?

Accepted Answer

NAT (Network Address Translation). NAT (Network Address Translation) allows multiple devices on a private network (like 192.168.1.x) to share a single public IPv4 address by translating the private source IP and port to the public IP and a unique port number when traffic exits the router. This enables all 15 workstations to access the internet simultaneously using the one public address provided by the ISP.

Answer

DNS (Domain Name System)

Answer

DHCP (Dynamic Host Configuration Protocol)

Answer

ARP (Address Resolution Protocol)

Question 13

A user reports that their desktop computer shuts down unexpectedly without warning, typically when playing graphics-intensive games or running video rendering software. The technician has verified that the CPU cooler is properly seated with fresh thermal paste and that all fans spin freely. The event logs show a kernel-power error 41. Which of the following should the technician do NEXT?

Accepted Answer

Test the power supply under load or replace it with a known-good unit. Kernel-power error 41 indicates an unexpected loss of power. Under heavy GPU load, a failing or underrated power supply can drop voltage or current, causing the system to shut down instantly. Since the CPU cooling is verified, the power supply is the most likely culprit.

Answer

Replace the RAM modules with known-good ones

Answer

Run a hard drive diagnostic test

Answer

Update the graphics card driver to the latest version

Question 14

A user's iPhone is not receiving any sounds from calls or notifications. The volume is turned up, and the silent switch is not enabled. The technician checks the Settings > Sounds & Haptics and sees that all alert volumes are at maximum. The user also reports that calls go directly to voicemail sometimes. Which of the following is the MOST likely cause?

Accepted Answer

Do Not Disturb mode is enabled.. Do Not Disturb (DND) mode silences all incoming calls and notifications while allowing the device to continue operating normally. Even with alert volumes at maximum and the silent switch disabled, DND will suppress sounds and can send calls directly to voicemail, matching the user's symptoms exactly.

Answer

The speaker hardware is faulty.

Answer

The phone's audio codec is corrupted.

Answer

The ringer switch is set to silent.

Question 15

A desktop powers on but repeatedly shuts down under load. The CPU temperature rises quickly even after dust is removed from the case. What should the technician inspect next?

Accepted Answer

CPU heatsink seating and thermal paste application. The CPU temperature rising quickly under load, even after dust removal, indicates that the heatsink is not making proper contact with the CPU or the thermal interface material has degraded. Inspecting the CPU heatsink seating and thermal paste application is the correct next step because poor thermal transfer causes the CPU to reach its thermal throttle or shutdown threshold, triggering a protective shutdown. This is a classic hardware troubleshooting step for overheating-related intermittent shutdowns.
