220-1101 Practice Test 34 — 15 Questions

Question 1

A company needs to deploy a cloud environment where the IT team can create virtual machines, configure virtual networks and firewalls, and install custom operating systems, all without managing any physical servers or networking hardware. Which cloud service model BEST meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides on-demand access to virtualized computing resources such as virtual machines, virtual networks, and firewalls, while abstracting the underlying physical hardware. The IT team retains full control over the operating system and network configuration without managing physical servers or networking hardware, which directly matches the requirement.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Desktop as a Service (DaaS)

Question 2

A company runs a customer-facing web application on a single virtual machine in a public cloud. After migrating to the cloud, users report that the application's response time varies significantly during the day, even though the VM's CPU and memory utilization stay below 50%. The cloud provider states that no resource limits are imposed on the VM. Which of the following cloud characteristics is MOST likely causing the performance variability?

Accepted Answer

Resource pooling. Resource pooling allows the cloud provider to dynamically allocate and reallocate physical resources (CPU, RAM, network bandwidth) among multiple tenants. Even though your VM shows low CPU/memory utilization, the underlying physical host's network I/O or storage throughput may be oversubscribed, causing contention during peak usage periods for other tenants on the same host. This shared infrastructure is the most likely cause of the observed performance variability, as the provider does not guarantee dedicated resources unless explicitly purchased.

Answer

Measured service

Answer

On-demand self-service

Answer

Rapid elasticity

Question 3

A user reports that their smartphone's screen remains dark when they press the power button, but they can hear incoming calls and notifications. The phone is fully charged. Which of the following is the most likely cause?

Accepted Answer

The proximity sensor is blocked.. The correct answer is C because a blocked proximity sensor is a common cause of a dark screen during calls. The proximity sensor detects when the phone is near the user's ear and turns off the display to prevent accidental touches. If the sensor is blocked (e.g., by a case, screen protector, or debris), the phone may incorrectly believe it is against the ear and keep the screen off even when the power button is pressed.

Answer

The display has failed completely.

Answer

The screen timeout is set to a very short duration.

Answer

The power button is stuck in the pressed position.

Question 4

A company uses a Type 1 hypervisor to host multiple virtual machines. One VM runs a legacy application that requires a specific MAC address for licensing. The administrator needs to move the VM from the current host to another physical host without changing the MAC address. Which of the following virtualization features should the administrator use?

Accepted Answer

C. Virtual network interface card (vNIC) MAC address assignment. Option C is correct because setting a static MAC address on the virtual network interface card (vNIC) allows the VM to retain its assigned MAC address regardless of which physical host it runs on. This is essential for the legacy application's licensing, which is tied to that specific MAC address. The administrator can configure this in the hypervisor's VM settings before or during migration.

Answer

A. Migration with hardware resource remapping

Answer

B. MAC address spoofing

Answer

D. Virtual switch port security

Question 5

Drag and drop the steps for configuring a SOHO wireless router into the correct order.

Question 6

A technician is troubleshooting a laptop that will not power on. The power adapter's LED is lit when plugged into the wall, but pressing the laptop's power button yields no response—no fans, no LEDs, and no beeps. The technician has already removed the battery and held the power button for 30 seconds to drain residual charge. Which of the following should the technician try NEXT?

Accepted Answer

Use a multimeter to measure the voltage at the tip of the power adapter.. The power adapter's LED is lit, indicating the wall outlet is supplying power, but the laptop shows no signs of life. The next logical step is to verify that the adapter is actually delivering the correct voltage to the laptop's power jack. Using a multimeter to measure the voltage at the tip of the adapter confirms whether the adapter itself is faulty, which is a common failure point before moving to internal components.

Answer

Remove the RAM modules and reseat them one at a time.

Answer

Replace the laptop's internal battery with a known-good battery.

Answer

Inspect the DC power jack on the laptop for physical damage.

Question 7

A technician is setting up a small office network. The router is configured with DHCP and provides addresses in the 192.168.1.0/24 range. A workstation obtains an IP address of 192.168.1.15 but cannot access any external websites. The workstation can ping the default gateway (192.168.1.1) and other local workstations. Which of the following is the most likely cause?

Accepted Answer

The DNS server address is not configured. The workstation can ping the default gateway and local devices, confirming that Layer 3 connectivity and the default gateway are functional. However, it cannot access external websites, which typically requires DNS resolution to translate domain names to IP addresses. Since the router's DHCP is configured but the workstation lacks a DNS server address, name resolution fails, preventing web access while IP-level communication remains intact.

Answer

The workstation's subnet mask is incorrect

Answer

The default gateway is not set

Answer

The router's DHCP pool is exhausted

Question 8

A technician is troubleshooting a desktop PC that was functioning normally before the user cleaned the inside with compressed air. After reassembly, the PC powers on (fans spin, LEDs light) but there is no video output and no POST beeps. The technician has already reseated the RAM, GPU, and all power cables. Which of the following should the technician do NEXT?

Accepted Answer

Clear the CMOS by removing the battery or using the jumper. Clearing the CMOS is the correct next step because the compressed air may have dislodged dust or created a static discharge that corrupted the BIOS/UEFI configuration, causing the system to fail POST without beeps. Reseating components already addressed loose connections, so the issue likely lies in the stored firmware settings, which a CMOS reset will restore to defaults.

Answer

Check the power supply voltages with a multimeter

Answer

Replace the motherboard

Answer

Replace the CPU 4+4 pin power cable

Question 9

A technician is troubleshooting a desktop computer that was functioning normally before a power outage. After the outage, pressing the power button causes the fans to spin briefly (about 1-2 seconds) and then stop. The power LED also lights momentarily. The technician has replaced the power supply unit with a known-good unit of the same wattage, but the symptom persists. The technician has verified the new PSU outputs correct voltages on all rails with a multimeter. Which of the following should the technician check NEXT?

Accepted Answer

B. The symptom of fans spinning briefly and then stopping, even after replacing the PSU with a known-good unit that outputs correct voltages, strongly indicates a short circuit or grounding issue on the motherboard. The PSU's overcurrent protection (OCP) or short-circuit protection (SCP) is triggering, causing it to shut down immediately to prevent damage. Since the PSU is verified good, the next logical step is to inspect the motherboard for physical damage, such as bulging capacitors, burn marks, or a short caused by a loose standoff screw.

Answer

A

D

Question 10

A technician is troubleshooting a desktop computer that powers on, all fans spin, and the keyboard and mouse receive power, but nothing is displayed on the monitor. The monitor's power LED is solid green, and the video cable is securely connected to the integrated graphics port. The technician has already reseated the RAM and tested with known-good RAM. The motherboard has no diagnostic LEDs or speaker. Which of the following should the technician do NEXT?

Accepted Answer

B. The correct answer is B because the symptoms—power on, fans spinning, peripherals powered, but no display—strongly suggest a POST failure where the system halts before initializing the GPU. Since the technician has already reseated and swapped RAM (a common cause), the next logical step is to reseat the CPU. A loose or improperly seated CPU can prevent the system from completing POST, even though fans and USB power are present, because the CPU is required to execute the BIOS/UEFI code that initializes the display output.

Question 11

A user dropped their Android smartphone and now the touchscreen is unresponsive in a small area near the top of the display. The screen is not cracked, and the LCD portion of the display still shows images correctly. Which component is MOST likely damaged?

Accepted Answer

Digitizer. The digitizer is the touch-sensitive layer that registers touch input. When a specific area of the touchscreen becomes unresponsive after a drop, but the LCD still displays images correctly, the digitizer is the most likely damaged component because it is a separate glass layer bonded to the LCD and is susceptible to impact damage even without visible cracks.

Answer

LCD panel

Answer

Battery

Answer

Motherboard

Question 12

A desktop computer will not boot after a thunderstorm. When powered on, the fans spin and LEDs light, but there is no POST, no beep codes, and no display. The technician has already tested the power supply with a multimeter (all voltages within specification), reseated all RAM and expansion cards, and tried a different monitor. On close inspection of the motherboard, the technician notices several electrolytic capacitors near the CPU voltage regulator module are bulging at the top with a brownish substance around their bases. Which of the following should the technician replace to resolve the issue?

Accepted Answer

Replace the motherboard.. The bulging electrolytic capacitors with brownish residue near the CPU voltage regulator module indicate physical failure, likely due to a power surge from the thunderstorm. Damaged capacitors prevent the motherboard from delivering stable voltage to the CPU, causing no POST, no beep codes, and no display even though fans and LEDs receive power. Since the power supply tested within specification and other components have been reseated, the motherboard itself is the faulty component and must be replaced.

Answer

Replace the power supply with a higher-wattage unit.

Answer

Replace the CPU with an identical or compatible model.

Answer

Replace the RAM modules with known-good units.

Question 13

A company wants to move its email system to the cloud to reduce the burden of managing servers, operating systems, and software updates. The IT team wants to configure only user mailboxes, email rules, and spam settings through a web-based admin console. The cloud provider will handle all underlying infrastructure, platform, and application maintenance. Which cloud service model BEST meets these requirements?

Accepted Answer

Software as a Service (SaaS). Software as a Service (SaaS) delivers a fully managed application, including email, where the cloud provider handles all underlying infrastructure, platform, and application maintenance. The IT team only needs to configure user mailboxes, rules, and spam settings via a web-based admin console, which is the hallmark of SaaS. This model eliminates the burden of managing servers, operating systems, and software updates, directly matching the company's requirements.

Answer

Infrastructure as a Service (IaaS)

Question 14

A technician is troubleshooting a laser printer that produces pages where the toner smudges easily and can be wiped off with a finger. The technician has already replaced the toner cartridge with a new OEM cartridge, but the problem persists. Which of the following printer components is MOST likely causing this issue?

Accepted Answer

Fuser assembly. The fuser assembly is responsible for melting toner particles into the paper fibers using heat and pressure. If the fuser is not reaching the correct temperature or is malfunctioning, the toner will not be permanently bonded to the page, causing it to smudge or wipe off easily. Since replacing the toner cartridge did not resolve the issue, the fuser is the most likely culprit.

Answer

Transfer roller

Answer

Pickup rollers

Answer

Corona wire

Question 15

A technician is troubleshooting a desktop computer that intermittently loses network connectivity for several minutes at a time. During the outage, the link light on the NIC remains on and flickers. The technician has already replaced the Ethernet cable and the NIC. The computer is connected to a managed switch port configured for auto-negotiation. Which of the following should the technician check NEXT?

Accepted Answer

The switch port for a duplex mismatch with the NIC. The link light remaining on and flickering during an outage indicates Layer 1 (physical) and Layer 2 (data link) connectivity are present, but the issue is likely a duplex mismatch. When one side of a link is set to full-duplex and the other to half-duplex (often due to failed auto-negotiation), collisions and frame errors cause intermittent connectivity loss lasting minutes. Since the cable and NIC have already been replaced, the next logical step is to check the switch port's duplex setting against the NIC's negotiated duplex.

Answer

The computer's IP address for a static conflict

Answer

The operating system's firewall settings

Answer

The network driver version for compatibility
