220-1101 Practice Test 36 — 15 Questions

Question 1

A desktop computer will not power on. The technician presses the power button, but there are no signs of activity—no fans, no LEDs. The power supply unit (PSU) is securely connected and the wall outlet is working. The technician uses a multimeter to check the PSU's main power connector. The technician finds that the green wire (PS_ON) goes low (0V) when the power button is pressed, indicating the motherboard is sending the signal to turn on. However, no other pins on the main connector show any voltage, and the PSU fan does not spin. Which of the following is the most likely cause?

Accepted Answer

The power supply unit has failed internally.. The green wire (PS_ON) going low (0V) confirms the motherboard is correctly signaling the PSU to turn on. Since no other pins show voltage and the PSU fan does not spin, the PSU is failing to convert AC to DC and distribute power internally, indicating an internal failure. A working PSU would respond to the PS_ON signal by activating its fan and outputting voltages on the other pins.

Answer

The power button is faulty.

Answer

The motherboard is not providing power to the PSU.

Answer

The CPU is not seated correctly.

Question 2

A company wants to move its email system to the cloud. The IT team wants to avoid managing physical servers and applying software updates, but they need full control over email policies, user accounts, and security settings. Which cloud service model BEST meets these requirements?

Accepted Answer

Software as a Service (SaaS). SaaS is the correct choice because it delivers the email application as a fully managed service, eliminating the need for the IT team to manage physical servers or apply software updates. At the same time, SaaS solutions like Microsoft 365 or Google Workspace provide granular administrative controls for email policies, user accounts, and security settings through web-based portals, meeting the requirement for full control without infrastructure management.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 3

A technician is setting up a small office network with a single internet connection from a cable modem. The office has two departments: Accounting and Sales. The technician needs to ensure that devices in Accounting cannot communicate with devices in Sales, but both departments must be able to access the internet. Which feature should the technician configure on the managed switch to meet this requirement?

Accepted Answer

Configure VLANs on the managed switch. VLANs (Virtual Local Area Networks) logically segment a switch into multiple isolated broadcast domains. By placing Accounting devices in one VLAN and Sales devices in another, the switch prevents Layer 2 communication between them, while both VLANs can still access the internet through a router configured with inter-VLAN routing or a separate uplink.

Answer

Enable DHCP on the router

Answer

Set up port forwarding on the router

Answer

Configure NAT on the router

Question 4

A technician is troubleshooting a desktop PC that fails to boot. When the power button is pressed, the system powers on for approximately 5 seconds, then shuts down and immediately restarts, repeating this cycle. The technician has replaced the power supply, reseated all components, and verified there are no loose screws or shorts. The motherboard has diagnostic LEDs, and the CPU LED glows solid red when the system attempts to start. The CPU is an Intel Core i7-12700K (LGA1700) installed in a compatible motherboard. The cooler is properly mounted with thermal paste applied. Which of the following is the MOST likely cause?

Accepted Answer

The motherboard BIOS version does not support the installed CPU.. The CPU LED glowing solid red indicates a CPU-related fault. Since the technician has already replaced the power supply, reseated components, and verified proper cooler mounting, the most likely cause is that the motherboard's BIOS version predates the microcode required for the Intel Core i7-12700K (Alder Lake, LGA1700). Many LGA1700 motherboards require a BIOS update to support 12th-gen CPUs; without it, the system fails to initialize the CPU, leading to the observed power cycle.

Answer

The CPU cooler is not making sufficient contact with the CPU.

Answer

The RAM modules are not fully seated in the correct slots.

Answer

The power supply unit is delivering insufficient wattage on the +12V rail.

Question 5

A technician is troubleshooting a desktop computer that was recently moved to a new location. The computer powers on and all fans spin, but the monitor remains black and the POST speaker emits a pattern of one long beep followed by two short beeps. The technician has already reseated the graphics card and the RAM modules. Which of the following should the technician check NEXT?

Accepted Answer

Verify that the monitor cable is securely connected to both the monitor and the graphics card.. The one long beep followed by two short beeps is a standard AMI BIOS POST code indicating a video adapter failure. Since the technician has already reseated the graphics card and RAM, the next most logical step is to verify the physical connection between the monitor and the graphics card, as a loose or disconnected cable can mimic a video failure by preventing the display from receiving a signal.

Answer

Replace the power supply unit.

Answer

Test the RAM in a different computer.

Answer

Update the motherboard BIOS.

Question 6

A technician is troubleshooting a desktop computer that randomly shuts down after about 20 minutes of use. The technician checks the event log and finds a critical thermal event. The technician verifies that both the CPU fan and case fans are spinning, and the CPU heatsink is securely attached. Which of the following should the technician do NEXT?

Accepted Answer

Apply new thermal paste between the CPU and heatsink.. The critical thermal event indicates the CPU is overheating despite the heatsink being securely attached and fans spinning. Over time, thermal paste can dry out or become less effective, reducing heat transfer between the CPU and heatsink. Applying new thermal paste restores proper thermal conductivity, which is the most likely fix given the symptoms and the technician's initial checks.

Answer

Replace the power supply.

Answer

Reinstall the operating system.

Answer

Run a memory diagnostic.

Question 7

A company maintains a private cloud for processing sensitive financial data. To handle occasional spikes in demand, they establish a VPN connection to a public cloud provider. When the on-premises infrastructure reaches 80% CPU utilization, an automation script provisions additional virtual servers in the public cloud, processes the workload, and then terminates them. Once the load returns to normal, only the private cloud resources are used. This architecture is an example of which cloud deployment model?

Accepted Answer

Hybrid cloud. This architecture combines a private cloud (on-premises infrastructure for sensitive financial data) with a public cloud (virtual servers provisioned via VPN during demand spikes), orchestrated by automation to burst capacity. The key is the integration of both environments through a VPN connection, which is the defining characteristic of a hybrid cloud model. The private cloud handles steady-state workloads, while the public cloud provides elastic overflow, ensuring sensitive data remains on-premises under normal conditions.

Answer

Community cloud

Answer

Public cloud

Answer

Virtual private cloud (VPC)

Question 8

A technician is troubleshooting a laser printer that produces pages with vertical white streaks. The toner cartridge has been replaced with a new OEM cartridge, and the imaging drum is clean. A test page printed from the printer's control panel also shows the streaks. Which of the following components is MOST likely causing the issue?

Accepted Answer

Laser scanning assembly. Vertical white streaks on a laser printer page indicate that the laser beam is being blocked or obstructed before it reaches the drum. Since the toner cartridge and imaging drum have been replaced and the issue persists, the most likely cause is a dirty or obstructed laser scanning assembly, which prevents the laser from exposing certain areas of the drum.

Answer

Fuser assembly

Answer

Transfer roller

Answer

Paper pickup rollers

Question 9

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 10

A company wants to migrate its internal web application to the cloud to reduce hardware maintenance costs and improve scalability. The IT team needs full control over the operating system and application software, but they want the cloud provider to manage the physical servers and virtualization layer. Which cloud service model best meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, giving the IT team full control over the operating system, applications, and middleware while the cloud provider manages the physical hardware and hypervisor layer. This matches the requirement for reduced hardware maintenance and scalability without sacrificing OS-level control.

Answer

Question 11

A technician is terminating an Ethernet cable for a 1000BASE-T network. The technician uses the T568A standard on one end and T568B on the other. Which of the following describes the resulting cable type?

Accepted Answer

Crossover. A crossover cable is created when one end is terminated with T568A and the other with T568B. In 1000BASE-T, all four pairs are used for bidirectional data transmission, and the crossover swaps the transmit and receive pairs (specifically pairs 1-2 and 3-6, and also pairs 4-5 and 7-8) to allow two like devices (e.g., two switches) to communicate directly without an uplink port.

Answer

Straight-through

Answer

Rollover

Answer

Loopback

Question 12

A multinational company is migrating its customer data to a cloud provider. Legal requirements mandate that all customer data must be stored on servers physically located within the country of origin. Which cloud characteristic must the company verify before selecting a provider?

Accepted Answer

Regional availability. Option C is correct because the company must ensure the cloud provider offers regional availability, meaning the provider has data centers physically located within the specific country required by law. This characteristic allows customers to select the geographic region where their data will be stored, directly addressing the legal mandate for data residency. Without regional availability, the provider might store data in any global location, violating compliance requirements.

Answer

Elasticity

Answer

High availability

Answer

Shared responsibility model

Question 13

A company uses a managed PoE switch to power IP phones. A new IP phone is connected to a wall jack that is patched to the switch. The switch port shows 'not powered' in the management interface, even though PoE is enabled globally and the phone is known to work. Which of the following is the MOST likely cause?

Accepted Answer

The PoE power budget for the switch has been exceeded. The most likely cause is that the PoE power budget for the switch has been exceeded. Even though PoE is enabled globally, the switch can only supply a finite amount of total power (e.g., 370W for a Cisco 3750X). If the cumulative power draw of all connected devices surpasses this budget, the switch will deny power to new devices, showing the port as 'not powered' while the phone itself is known to work.

Answer

The patch cable is a crossover cable

Answer

The IP phone requires a higher PoE standard than the switch supports

Answer

The port is administratively disabled

Question 14

A company runs a private cloud with multiple virtualization hosts. To meet an SLA requirement, the IT administrator needs to ensure that if a physical host fails, the virtual machines running on that host are automatically restarted on another healthy host with minimal manual intervention. Which virtualization feature should the administrator implement?

Accepted Answer

High availability. High availability (HA) is the correct feature because it automatically detects a physical host failure and restarts the affected virtual machines on another healthy host within the cluster, meeting the SLA requirement for minimal manual intervention. HA relies on a heartbeat mechanism between hosts and a management platform (e.g., vSphere HA) to trigger the restart process without requiring user action.

Answer

Load balancing

Answer

Live migration

Answer

Resource pooling

Question 15

A company runs multiple virtual machines on a single physical server. The hypervisor is installed directly on the server hardware and does not require an underlying operating system. This configuration is an example of which of the following?

Accepted Answer

Type 1 hypervisor. A Type 1 hypervisor, also known as a bare-metal hypervisor, runs directly on the physical hardware without requiring an underlying operating system. This configuration is used in enterprise data centers to host multiple virtual machines efficiently, as the hypervisor has direct access to hardware resources like CPU, memory, and I/O, minimizing overhead.

Answer

Type 2 hypervisor

Answer

Infrastructure as a Service

Answer

Virtual Desktop Infrastructure
