220-1101 Practice Test 12 — 15 Questions

Question 1

A user can access local network resources but cannot browse the internet. Other users on the same network have no issues. The technician checks the workstation's IP configuration: IP 192.168.1.100, subnet mask 255.255.255.0, default gateway 192.168.1.1, DNS server 192.168.1.1. The workstation successfully pings the default gateway (192.168.1.1). The technician then tries to ping 8.8.8.8 and the ping fails. Which of the following should the technician check NEXT?

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

Accepted Answer

The routing table on the router. Since the workstation can ping the default gateway (192.168.1.1) but cannot ping 8.8.8.8, the issue is beyond the local subnet. This indicates a routing problem, not a local connectivity or DNS issue. The technician should check the router's routing table to ensure there is a default route (0.0.0.0/0) pointing to the ISP or upstream gateway, as the router may not be forwarding traffic to external networks.

Answer

The switch port configuration

Answer

The DNS server settings

Answer

The DHCP lease expiration

Question 2

A user reports that their smartphone's battery drains very quickly even when the phone is idle. The technician checks battery health in settings and it shows 'Normal.' No single app reports excessive power consumption. The phone also feels warm to the touch while not in use. Which of the following is the MOST likely cause?

Accepted Answer

The phone is infected with malware. The phone feels warm while idle and drains battery quickly despite no single app showing high usage, which strongly suggests background activity from malware. Malware can run hidden processes, keep the CPU active, and maintain network connections, generating heat and draining power without appearing in standard battery usage lists. The battery health being 'Normal' rules out a faulty battery as the primary cause.

Answer

The battery is faulty and needs replacement

Answer

The operating system requires an update

Answer

The phone's charging port is damaged

Question 3

A technician is troubleshooting a desktop computer that consistently shuts down after approximately 30 minutes of normal operation. The technician has already replaced the power supply unit and cleaned the CPU heatsink of dust. The CPU temperatures in the BIOS are normal (35°C idle). After the shutdown, the event log shows a 'Kernel-Power 41' critical error. The technician reseated all power cables and checked for loose connections. Which of the following should the technician check NEXT?

Accepted Answer

The motherboard's capacitors for signs of bulging or leaking.. The Kernel-Power 41 error indicates an unexpected loss of power or system instability, not a software crash. Since the PSU has been replaced and the CPU temperatures are normal, the most likely hardware cause is failing motherboard capacitors, which can cause intermittent shutdowns under load as they lose their ability to filter voltage ripple. Bulging or leaking capacitors are a common failure point on aging motherboards and should be visually inspected next.

Answer

The RAM modules for errors using a diagnostic tool.

Answer

The hard drive for bad sectors.

Answer

The power button for sticking.

Question 4

A company runs its customer relationship management (CRM) application on a single virtual machine (VM) in a public cloud IaaS environment. During the workday, the application's response time becomes highly variable and often slow, even though the VM's CPU and memory utilization rarely exceed 50%. The cloud provider states that the physical host is a shared multi-tenant server. Which cloud computing concept is MOST likely causing this performance degradation?

Accepted Answer

Resource pooling leading to the 'noisy neighbor' effect. The performance degradation is most likely due to resource pooling in a multi-tenant IaaS environment, where the 'noisy neighbor' effect occurs. Even though the VM's own CPU and memory utilization are low, another VM on the same physical host may be consuming shared resources like disk I/O or network bandwidth, causing contention. This is a classic symptom of a shared hypervisor where one tenant's workload starves others of critical I/O resources.

Answer

Rapid elasticity causing the VM to be moved between hosts

Answer

Measured service billing that throttles the VM

Answer

Lack of scalability in the application design

Question 5

A company uses a cloud provider to host a legacy application that requires a specific hardware serial number (e.g., the BIOS UUID of the physical server) for licensing. The licensing software checks this identifier at startup and will not run on hardware with a different serial number. The company wants to maintain control over the underlying hardware and ensure the serial number remains constant. Which cloud deployment model would BEST meet this requirement?

Accepted Answer

Private cloud. A private cloud is the correct choice because it allows the company to maintain exclusive control over the underlying physical hardware. In a private cloud, the organization owns or leases the servers and can ensure the BIOS UUID remains constant, satisfying the legacy application's licensing requirement. Public, hybrid, and community clouds typically abstract or share hardware, making it impossible to guarantee a fixed hardware serial number.

Answer

Public cloud

Answer

Hybrid cloud

Answer

Community cloud

Question 6

A technician is building a new desktop computer. After installing the CPU, RAM, and power supply, the system powers on and fans spin, but the monitor displays 'No Signal'. The technician has verified the monitor and cable work with another computer. Which of the following should the technician check FIRST?

Accepted Answer

Ensure the CPU power connector is plugged in. The CPU power connector (typically a 4+4 pin 12V EPS connector) provides dedicated power to the CPU. Without it, the CPU cannot initialize, so the system may power on and spin fans but fail to POST, resulting in a 'No Signal' display. Since the monitor and cable are verified working, the most logical first check is this power connection.

Answer

Replace the RAM with known good modules

Answer

Reseat the GPU in its slot

Answer

Check the BIOS settings for video output

Question 7

A technician is troubleshooting a desktop computer that shuts down unexpectedly after about 10 minutes of playing a graphics-intensive game. The technician checks the CPU temperature, which stays at 45°C at idle but reaches 95°C under load just before shutdown. The heatsink and fan are clean and spinning properly. The power supply is a 650W unit, and the graphics card is a high-end model that draws up to 350W. Which of the following is the MOST likely cause of the shutdowns?

Accepted Answer

The thermal paste between the CPU and heatsink has degraded. The CPU temperature reaching 95°C under load just before shutdown indicates a thermal throttling or thermal protection shutdown. Since the heatsink and fan are clean and spinning properly, the most likely cause is degraded thermal paste, which reduces heat transfer efficiency from the CPU to the heatsink, causing the CPU to overheat despite adequate cooling hardware.

Answer

The power supply is insufficient for the graphics card

Answer

The CPU fan is not spinning fast enough

Answer

The graphics card is overheating

Question 8

A technician is troubleshooting a workstation that shuts down randomly after running for 20-30 minutes. The technician has reseated the RAM modules, confirmed the power supply voltages are within specification using a multimeter, and verified that all case fans are spinning. The system has a dedicated graphics card. Which of the following should the technician do NEXT to diagnose the issue?

Accepted Answer

Check the CPU cooler for proper contact and reapply thermal paste. The random shutdown after 20-30 minutes strongly indicates thermal throttling or overheating. Since the technician has already verified power supply voltages and case fan operation, the most likely cause is inadequate CPU cooling due to poor contact between the CPU cooler and the processor or dried-out thermal paste. Reseating the RAM and checking fans would not address a CPU thermal issue, so checking the CPU cooler and reapplying thermal paste is the correct next step.

Answer

Replace the motherboard

Answer

Update the GPU driver

Answer

Disable the onboard network interface card (NIC)

Question 9

A technician builds a new desktop computer. When powered on, all fans spin and LEDs light up, but the monitor shows 'No Signal'. The monitor is known to work. The motherboard has no onboard video output. The GPU fans spin. Which of the following should the technician check FIRST?

Accepted Answer

Verify the GPU power cables are fully seated.. The GPU fans spinning indicates the card is receiving power from the PCIe slot, but the monitor showing 'No Signal' suggests the GPU may not be receiving sufficient supplemental power. The most common cause is a loose or unseated PCIe power cable from the PSU to the GPU. Checking and reseating these cables is the quickest, least invasive step before attempting reseating or replacement.

Answer

Reseat the GPU in its PCIe slot.

Answer

Connect the monitor to the motherboard's video output.

Answer

Replace the GPU with a known-working unit.

Question 10

A technician builds a new desktop computer and installs a high-end dedicated graphics card. The system boots into Windows, but the display resolution is locked at 800x600 and the option to change it is grayed out. In Device Manager, the graphics card is listed under 'Other devices' with a yellow exclamation mark. Which of the following steps should the technician perform FIRST?

Accepted Answer

Install the latest graphics driver from the manufacturer's website.. The yellow exclamation mark in Device Manager under 'Other devices' indicates that Windows has not loaded a proper driver for the graphics card, which is why the display is stuck at the generic VGA resolution of 800x600. Installing the latest driver from the manufacturer's website is the correct first step because the operating system cannot utilize the dedicated GPU's capabilities without the correct driver, and this is the most common cause of the described symptoms.

Answer

Enable the device in the system BIOS.

Answer

Reseat the graphics card in the PCIe slot.

Answer

Disable the integrated graphics in the BIOS.

Question 11

A cloud provider tracks a customer's usage of storage, processing power, and network bandwidth on a per-hour basis. At the end of the month, the customer receives a bill that exactly matches the resources consumed. Which essential cloud characteristic does this scenario BEST illustrate?

Accepted Answer

C. Measured service. The scenario describes a cloud provider tracking resource usage (storage, processing power, network bandwidth) per hour and billing exactly for what was consumed. This directly illustrates the 'Measured service' characteristic, where cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). The pay-per-use billing model is a direct outcome of this measured service.

Answer

A. Rapid elasticity

Answer

B. On-demand self-service

Answer

D. Resource pooling

Question 12

A technician builds a new PC. When powering on, all fans spin and LEDs light, but the monitor shows 'No Signal'. The motherboard has a CPU diagnostic LED that remains lit. The technician has already reseated the RAM and GPU, and verified the monitor and cable are functional. Which of the following should the technician do NEXT?

Accepted Answer

Reseat the CPU and check for bent pins.. The CPU diagnostic LED remaining lit indicates a CPU-related fault. Since the technician has already reseated RAM and GPU and verified the monitor and cable, the next logical step is to reseat the CPU and inspect the CPU socket for bent pins. Bent pins can prevent proper contact between the CPU and motherboard, causing the CPU diagnostic LED to stay on and the system to fail POST.

Answer

Replace the power supply.

Answer

Update the motherboard BIOS.

Answer

Test the RAM in another system.

Question 13

A technician builds a new desktop computer. After pressing the power button, the system powers on for about 5 seconds, then shuts down, and then immediately attempts to power on again, repeating the cycle. The technician has verified that all power connections are secure and has reseated the CPU and RAM. Which of the following should the technician check NEXT?

Accepted Answer

The CPU heatsink fan connection. The symptom of a system powering on for a few seconds, then shutting down and immediately rebooting in a cycle is classic behavior of a thermal or overheat protection trigger. The CPU heatsink fan connection (option B) is the most likely cause because if the fan is not connected or is faulty, the CPU rapidly overheats, causing the motherboard's thermal protection circuitry to shut down the system; it then attempts to restart, only to overheat again, creating the loop. The technician has already reseated the CPU and RAM, so the next logical step is to verify the CPU cooler's power connection.

Answer

The power supply voltage selector switch

Answer

The front panel power switch header

Answer

The CMOS battery

Question 14

A company operates a private cloud environment with a cluster of physical hosts running virtual machines. The IT administrator wants to ensure that if a physical host fails unexpectedly, the virtual machines running on that host will be automatically restarted on another healthy host in the cluster without manual intervention. Which feature should the administrator configure?

Accepted Answer

High availability (HA). High Availability (HA) is the correct feature because it is designed to automatically restart virtual machines on another healthy host within a cluster when a physical host fails. HA uses heartbeat monitoring between hosts and the vCenter Server (or equivalent management platform) to detect failures, then triggers VM restarts on surviving hosts without manual intervention. This directly matches the requirement for automatic recovery from an unexpected host failure.

Answer

Fault tolerance (FT)

Answer

Load balancing

Answer

Live migration

Question 15

A technician needs to replace a cracked LCD screen on an Android smartphone. After disassembling the phone and disconnecting the old screen, which of the following should the technician do FIRST before installing the new screen?

Accepted Answer

Remove or disconnect the battery. The correct first step before installing a new screen is to remove or disconnect the battery. This ensures the device is completely powered off and eliminates the risk of short circuits or electrostatic discharge (ESD) that could damage the new LCD or other sensitive components during installation. Even if the phone appears off, residual charge in capacitors can cause damage if the battery remains connected.

Answer

Connect the new screen and test the display immediately

Answer

Apply adhesive to the frame to secure the new screen

Answer

Update the smartphone's firmware to the latest version
