220-1101 Practice Test 14 — 15 Questions

Question 1

A cloud administrator is migrating a virtual machine from a private cloud to a public cloud. The VM must retain its hostname and IP address. The public cloud provider does not support the same hypervisor as the private cloud. Which of the following migration methods is MOST appropriate?

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

Accepted Answer

Virtual-to-virtual (V2V). Virtual-to-virtual (V2V) migration is the correct method because it converts a virtual machine from one hypervisor format to another, allowing the VM to run on a public cloud provider that uses a different hypervisor than the private cloud. This process preserves the guest OS, applications, and configuration, including the hostname and IP address, by converting the virtual disk and metadata to the target hypervisor's format.

Answer

Physical-to-virtual (P2V)

Answer

Live migration

Answer

Cloning

Question 2

A technician is assembling a new desktop PC. The motherboard is an LGA1700 socket type, and the technician installs the CPU, heatsink, and RAM. When powering on, the system turns on for a few seconds then shuts off and restarts repeatedly. The technician has verified that the power supply is functional and all power cables are connected. Which of the following is the most likely cause?

Accepted Answer

The CPU cooler is not making proper contact. The LGA1700 socket requires the CPU cooler to apply even and sufficient pressure to prevent thermal runaway. If the cooler is not making proper contact, the CPU rapidly overheats, triggering thermal protection that shuts down the system within seconds, followed by a restart loop. This matches the symptom of powering on briefly then repeatedly cycling.

Answer

The CPU is not compatible with the motherboard

Answer

The RAM is installed in the wrong slots

Answer

The motherboard is shorting against the case

Question 3

A user reports that their iPhone 12 is stuck in a continuous boot loop—it shows the Apple logo, then turns off, and repeats. The user has already performed a force restart (Volume Up, Volume Down, hold Side button) multiple times without success. The iPhone is still running the original iOS version. Which of the following should the user try next to resolve this issue?

Accepted Answer

Connect the iPhone to a computer and put it into recovery mode, then restore via Finder or iTunes. A continuous boot loop on an iPhone that persists after a force restart typically indicates a corrupted operating system or failed firmware update. Since the iPhone is still on its original iOS version, the most effective next step is to connect it to a computer, put it into recovery mode (by pressing and releasing Volume Up, then Volume Down, then holding the Side button until the recovery mode screen appears), and restore the device via Finder (macOS Catalina or later) or iTunes (Windows or older macOS). This process reloads the iOS firmware and resolves software-level boot failures without requiring hardware replacement.

Answer

Replace the battery

Answer

Disconnect and reconnect the internal battery

Answer

Perform a factory reset from the Settings app

Question 4

A network technician is configuring a small office network. The office has two departments: Sales and Accounting. The technician needs to ensure that devices in Sales cannot communicate with devices in Accounting, but both departments must be able to access the internet. The network uses a single router and one managed switch. Which of the following should the technician configure on the switch?

Accepted Answer

VLANs. VLANs (Virtual Local Area Networks) allow the technician to logically segment the switch into separate broadcast domains. By placing Sales devices in one VLAN and Accounting devices in another, inter-VLAN communication is blocked at Layer 2, while both VLANs can still access the internet through the single router (which performs inter-VLAN routing if configured, but here only internet access is needed, so the router can simply provide default gateway connectivity without routing between VLANs).

Answer

Port mirroring

Answer

Link aggregation

Answer

Spanning Tree Protocol

Question 5

A user's smartphone screen is cracked and the touch is unresponsive in the cracked area. The technician replaces the screen assembly. After reassembly, the phone powers on, displays correctly, but the touch still does not work in the same area. What should the technician check first?

Accepted Answer

Digitizer cable connection. The digitizer is the component responsible for touch input, and it connects to the mainboard via a separate cable from the LCD. If the touch remains unresponsive in the same area after replacing the screen assembly, the most likely cause is a loose, damaged, or improperly seated digitizer cable connection. The display works correctly, which confirms the LCD cable is fine, isolating the issue to the digitizer.

Answer

LCD cable connection

Answer

Battery connection

Answer

Proximity sensor

Question 6

A technician builds a high-end gaming PC. The motherboard supports PCIe 4.0, the CPU supports it, and the graphics card is PCIe 4.0. The technician installs a new NVMe SSD in the M.2 slot. The system boots, but the SSD is not detected in the BIOS or Windows. The technician has tried reseating the SSD and checking the motherboard manual. Which of the following is the MOST likely cause?

Accepted Answer

The SSD is installed in a SATA-only M.2 slot, but the SSD is NVMe.. Many motherboards have M.2 slots that support only SATA or only NVMe (PCIe) protocols. If an NVMe SSD is inserted into a SATA-only M.2 slot, the SSD will not be detected by the BIOS or Windows. The motherboard manual would typically specify which M.2 slots support which protocols, and the technician should verify that the slot used supports PCIe/NVMe.

Answer

The SSD is incompatible with the motherboard chipset.

Answer

The M.2 slot is disabled in the BIOS.

Answer

The CPU is not seated correctly causing PCIe lanes to not work.

Question 7

A company uses a public IaaS provider to host a web application. To protect against DDoS attacks, they configure a security appliance that inspects incoming traffic before it reaches the web servers. This appliance runs on a separate virtual machine in the same cloud environment. Which of the following cloud security concepts does this scenario BEST describe?

Accepted Answer

Network virtual appliance. The scenario describes a security appliance running on a separate virtual machine that inspects incoming traffic before it reaches the web servers. This is the definition of a Network Virtual Appliance (NVA) — a virtual machine-based security device (e.g., virtual firewall, IDS/IPS) deployed in a public IaaS environment to filter or inspect traffic. Option C is correct because the appliance is explicitly a separate VM performing a dedicated network security function, which is the core characteristic of an NVA.

Answer

Virtual private cloud (VPC)

Answer

Security group

Answer

Resource pooling

Question 8

A technician is deploying a new virtual machine for a development team. The host server has limited physical storage, and the VM will be used for testing software that requires a minimal amount of disk space initially. However, the development team anticipates that the VM's disk usage will grow significantly over time as more software is installed. The technician wants to allocate the required storage in a way that does not consume the entire allotment upfront, allowing the host to overcommit storage. Which virtualization feature should the technician configure for the VM's virtual hard disk?

Accepted Answer

Thin provisioning. Thin provisioning allows the virtual hard disk to be created with a specified maximum size but only consumes physical storage on the host as data is written to the VM. This enables storage overcommitment, where the host can allocate more virtual disk space than physical storage exists, because the unused space is not pre-allocated. This matches the requirement to avoid consuming the entire allotment upfront while accommodating future growth.

Answer

Thick provisioning (eager zeroed)

Answer

Thick provisioning (lazy zeroed)

Answer

Deduplication

Question 9

A technician is troubleshooting a workstation that randomly reboots when the user performs disk-intensive operations, such as copying large files. The technician has replaced the power supply and tested the RAM (no errors). The hard drive passes S.M.A.R.T. tests. The motherboard capacitors appear normal. The technician suspects a thermal issue but CPU and GPU temps are normal. Which component should the technician check next?

Accepted Answer

The voltage regulator modules (VRMs) on the motherboard, which may be overheating under load.. The VRMs regulate voltage to the CPU and can overheat under sustained load, especially during disk-intensive operations that also stress the CPU. Overheating VRMs can cause voltage instability or thermal shutdown, leading to random reboots even when CPU/GPU temperatures appear normal. This matches the symptom pattern after ruling out PSU, RAM, and storage issues.

Answer

The SATA data cable, which may be faulty causing intermittent disconnects.

Answer

The case fans, which may not be providing adequate airflow to the chipset.

Answer

The operating system power plan settings, which may be set to balanced.

Question 10

A technician is upgrading the CPU in a desktop computer. The new CPU is listed as compatible with the motherboard on the manufacturer's website. After installing the CPU, heatsink, and connecting the CPU power cable, the system powers on (fans spin, LEDs light) but there is no display and no POST beeps. The motherboard has a set of diagnostic LEDs; the CPU LED is stuck on. The technician has verified that the CPU is installed correctly in the socket with no bent pins. Which of the following should the technician do NEXT?

Accepted Answer

Update the motherboard's BIOS/UEFI firmware. The CPU is listed as compatible, but the motherboard may require a BIOS/UEFI firmware update to support the new CPU's microcode. The stuck CPU diagnostic LED indicates the motherboard cannot initialize the CPU, which is a classic symptom of a firmware compatibility issue rather than a hardware defect.

Answer

Replace the CPU with a known-good one

Answer

Reseat the RAM modules

Answer

Test the power supply under load

Question 11

A technician is troubleshooting a small office network where Windows computers can ping each other by IP address but cannot access shared folders using Universal Naming Convention (UNC) paths (e.g., \COMPUTER1\Share). The computers are all in the same workgroup and subnet. The technician checks the network settings and sees that all computers have the correct default gateway and DNS server configured. Which of the following should the technician verify?

Accepted Answer

NetBIOS over TCP/IP setting. NetBIOS over TCP/IP (NBT) is required for Windows to resolve NetBIOS names (like COMPUTER1) to IP addresses when using UNC paths. Even though ping works via DNS or hosts file, file sharing relies on NetBIOS name resolution unless DNS is configured to handle the single-label name. If NBT is disabled, the client cannot resolve the computer name in the UNC path, causing the access failure.

Answer

DHCP scope configuration

Answer

DNS suffix assignment

Answer

WINS server address

Question 12

A user reports that their laptop loses network connectivity whenever they unplug the AC power adapter. When running on battery power alone, the laptop's Wi-Fi works intermittently or disconnects. The technician has verified that the Wi-Fi adapter driver is up to date and that the router is functioning correctly. Which of the following should the technician do NEXT to resolve this issue?

Accepted Answer

Disable the power-saving feature for the wireless adapter in Device Manager.. The issue is that the Wi-Fi adapter disconnects when the laptop switches to battery power, which is a classic symptom of the power-saving feature for the wireless adapter being enabled. This feature, controlled via the Power Management tab in Device Manager, can reduce power to the adapter to conserve battery life but often causes intermittent connectivity or disconnects. Disabling 'Allow the computer to turn off this device to save power' resolves the problem without replacing hardware or changing the overall power plan.

Answer

Replace the Wi-Fi adapter.

Answer

Update the BIOS firmware.

Answer

Change the power plan to High Performance.

Question 13

A technician is building a new desktop computer using an AMD Ryzen 5 5600X CPU and a B450 chipset motherboard. After assembling all components, the system powers on. The case fans and CPU fan spin, but there is no display output. The motherboard's CPU debug LED remains lit. The technician has already reseated the CPU (no bent pins), verified the RAM is seated correctly, and tested the power supply with a multimeter (voltages within specification). The GPU works in another system. Which of the following should the technician do NEXT?

Accepted Answer

Update the motherboard BIOS to a version that supports Ryzen 5000 series processors. The AMD Ryzen 5 5600X is a Vermeer (Zen 3) processor, while B450 motherboards originally launched with support for Ryzen 2000 (Pinnacle Ridge) and Ryzen 3000 (Matisse) CPUs. A BIOS update is required to add the AGESA microcode that enables Zen 3 support. The CPU debug LED staying lit indicates the motherboard cannot initialize the CPU, which is the classic symptom of an incompatible BIOS version.

Answer

Replace the power supply unit with a higher wattage model

Answer

Reseat the GPU in a different PCIe slot

Answer

Replace the CMOS battery and clear the CMOS

Question 14

A company runs a critical web application on a virtual machine in a public cloud. To ensure high availability during traffic spikes and hardware failures, the administrator wants to distribute incoming traffic across multiple identical VMs. Which of the following cloud solutions BEST meets this requirement?

Accepted Answer

Deploy a load balancer to distribute traffic across the VM instances.. A load balancer (Option B) is the correct solution because it actively distributes incoming traffic across multiple identical VM instances, providing high availability by automatically rerouting traffic away from failed instances. Unlike DNS-based methods, a load balancer performs health checks and can handle traffic spikes without relying on client-side caching or TTL propagation delays.

Answer

Configure an auto-scaling group to add more VMs during high demand.

Answer

Set up DNS round-robin with multiple A records pointing to each VM.

Answer

Establish a site-to-site VPN connection to the cloud provider's network.

Question 15

A server administrator needs to apply a critical security patch to a production virtual machine. The patch has the potential to cause the VM to become unstable. Which of the following should the administrator do FIRST to minimize the risk of a prolonged outage?

Accepted Answer

Take a snapshot of the VM. Taking a snapshot captures the VM's current state, including disk data and memory, allowing the administrator to revert instantly if the patch causes instability. This minimizes downtime compared to a full backup, which requires a restore process. Snapshots are designed for quick rollback in virtualized environments like VMware vSphere or Hyper-V.

Answer

Create a full backup of the VM to a separate storage location

Answer

Migrate the VM to another physical host

Answer

Power off the VM before applying the patch
