220-1101 Practice Test 9 — 10 Questions

Question 1

A user reports that after moving their desktop computer to a new desk, the network connection no longer works. The technician notices that the Ethernet cable is plugged into the computer and the wall jack, but the link lights on the computer's NIC and the wall jack are off. The cable is a flat-style Cat5e cable that came with the computer. Which of the following is the most likely cause?

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

Accepted Answer

The cable is damaged from bending. Flat-style Ethernet cables are more susceptible to damage from bending or kinking than round cables because their conductors are arranged in a parallel plane, which can cause conductor fractures or impedance mismatches when flexed. Since the cable was moved and the link lights are off on both the NIC and the wall jack, the most likely cause is physical damage to the cable from bending during the move, breaking the electrical continuity.

Answer

The cable is not Cat6

Answer

The wall jack is not terminated properly

Answer

The NIC is disabled in the OS

Question 2

A company runs a web application on a virtual machine in a public cloud. During a marketing campaign, the application experiences a sudden spike in traffic. The cloud platform automatically adds more virtual server instances to handle the load and then removes them when traffic subsides. Which cloud computing characteristic does this represent?

Accepted Answer

Rapid elasticity. Rapid elasticity is the cloud characteristic that enables resources to scale out (add instances) and scale in (remove instances) automatically in response to demand spikes, such as during a marketing campaign. This is distinct from resource pooling, which refers to multi-tenant sharing of physical infrastructure, not dynamic scaling.

Answer

Resource pooling

Answer

Measured service

Answer

On-demand self-service

Question 3

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 4

A technician is upgrading a desktop computer by installing a new high-end graphics card that requires two 8-pin PCIe power connectors. The existing power supply unit (PSU) is a 500W unit with only one 8-pin connector. The technician uses a Y-splitter adapter to power both connectors on the GPU from the single 8-pin rail. After powering on, the computer boots but the display remains blank, and the GPU's fans do not spin. Which of the following is the MOST likely cause?

Accepted Answer

The power supply does not provide enough wattage for the GPU. The most likely cause is that the 500W power supply does not provide enough wattage for the new high-end graphics card. Even though the Y-splitter adapter allows two physical connections, it draws power from a single 8-pin rail, which is limited to 150W (plus 75W from the PCIe slot). A high-end GPU typically requires 250W or more, and the total system load may exceed the PSU's capacity, causing the GPU to fail to initialize and its fans not to spin.

Answer

The GPU is not properly seated in the PCIe slot

Answer

The Y-splitter adapter is defective

Answer

The monitor cable is not correctly connected

Question 5

A technician is replacing the storage drive in a desktop computer. The motherboard has an M.2 slot that supports both SATA and NVMe interfaces. The technician installs an NVMe M.2 SSD into this slot. Which of the following statements is true?

Accepted Answer

The SSD will operate at NVMe speeds as long as the slot is configured for PCIe connectivity.. The M.2 slot on the motherboard supports both SATA and NVMe interfaces, but the NVMe protocol operates over PCIe lanes. When an NVMe M.2 SSD is installed, it will communicate using the PCIe bus, achieving NVMe speeds, provided the slot is electrically configured for PCIe connectivity (which is standard for NVMe support). The slot's compatibility with SATA does not force the NVMe drive to use SATA protocol; the drive negotiates the highest supported interface.

Answer

The SSD will operate at SATA speeds because the slot supports both.

Answer

The SSD will require a separate SATA power cable from the power supply.

Answer

The SSD must be a SATA M.2 type to work in this slot.

Question 6

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 7

A company develops a custom web application that requires a specific runtime environment and middleware. The company wants to avoid managing the underlying servers, operating system patches, and runtime scaling. They choose a cloud service where they can upload their application code and the provider automatically handles the OS, runtime, and scaling based on demand. Which cloud service model does this describe?

Accepted Answer

Platform as a Service (PaaS). This scenario describes Platform as a Service (PaaS), where the cloud provider manages the underlying infrastructure, operating system, runtime environment, and middleware. The customer only needs to upload their application code, and the provider automatically handles scaling, patching, and runtime dependencies. This contrasts with IaaS, where the customer manages the OS and runtime, and SaaS, where the provider delivers a fully functional application.

Answer

Infrastructure as a Service (IaaS)

Answer

Software as a Service (SaaS)

Answer

Desktop as a Service (DaaS)

Question 8

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 9

A user's smartphone has a cracked screen that is still partially functional, but the touch input does not work in the cracked area. The user wants to back up all data before taking it for repair. Which method would be MOST reliable to back up the data if the screen is unresponsive?

Accepted Answer

Use a cloud backup service that was previously enabled.. If a cloud backup service (e.g., iCloud, Google Drive, Samsung Cloud) was previously enabled and configured to back up automatically, the user can restore the data after the repair without needing any screen interaction. This method does not require the touchscreen to be functional, as backups occur in the background over Wi-Fi. It is the most reliable approach when the screen is unresponsive and no prior wired connection was established.

Answer

Connect the phone to a computer via USB and use file explorer.

Answer

Use an OTG cable to connect a mouse.

Answer

Use the phone's recovery mode to perform a full backup.

Question 10

A user's Android smartphone charges normally when powered off and connected to a wall charger. However, when the phone is powered on and connected to the same charger, the battery percentage decreases over time despite showing the charging icon, eventually causing the phone to shut down. The user has tried multiple charging cables and adapters, performed a factory reset, and the issue persists. Which of the following is the MOST likely cause?

Accepted Answer

The battery has reached end-of-life and cannot hold a charge. The fact that the phone charges normally when powered off but discharges when powered on indicates that the battery can accept a charge but cannot supply enough current to meet the device's operational demands. This is a classic symptom of a battery that has reached its end-of-life, where its internal resistance has increased significantly, causing the voltage to sag under load. The factory reset and cable/adapter swaps rule out software and accessory issues, isolating the battery as the most likely culprit.

Answer

The charging port is loose or damaged

Answer

The operating system has a bug causing high power drain

Answer

The mainboard's charging IC is malfunctioning
