220-1101 Practice Test 13 — 15 Questions

Question 1

A user reports that their smartphone battery drains significantly faster after a recent OS update. Which of the following should the technician do FIRST to address this issue?

Accepted Answer

Check the battery usage statistics in the settings menu. The first step in troubleshooting battery drain after an OS update is to check the battery usage statistics in the settings menu. This allows the technician to identify which apps or services are consuming excessive power, often due to background processes or misconfigured settings introduced by the update. Replacing hardware or performing a full OS reinstall without first diagnosing the cause is premature and may not resolve the issue.

Answer

Replace the battery with a new one

Answer

Perform a factory reset and restore from backup

Answer

Reinstall the operating system using the latest firmware

Question 2

A company currently hosts its own on-premises email server. To reduce hardware maintenance overhead, they decide to move the email server to the cloud. They require the ability to install and manage their own email application (e.g., Microsoft Exchange), including the underlying operating system, while the cloud provider is responsible for the physical infrastructure 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, including virtual machines with full control over the operating system and applications. This model allows the company to install and manage their own email application (e.g., Microsoft Exchange) and the underlying OS, while the cloud provider handles the physical hardware and virtualization layer. The requirement to manage the OS and application rules out PaaS and SaaS, which abstract away that control.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Desktop as a Service (DaaS)

Question 3

A technician builds a new desktop computer. When starting the system for the first time, the screen displays a 'CPU Fan Error' message and the system prompts to press F1 to continue. The technician checks the CPU cooler fan and observes that it is spinning. Which of the following should the technician check NEXT?

Accepted Answer

The CPU fan is connected to a case fan header instead of the CPU fan header. The 'CPU Fan Error' message is triggered when the motherboard does not detect a fan connected to the dedicated CPU fan header (usually labeled CPU_FAN). Even if the fan is spinning, connecting it to a case fan header (SYS_FAN or CHA_FAN) will not satisfy the CPU fan monitoring circuit, as the BIOS specifically polls the CPU_FAN header for a tachometer signal. This is the most likely cause given the fan is physically operational.

Answer

The CPU thermal paste was applied insufficiently

Answer

The power supply is not providing enough power to the fan

Answer

The CPU heatsink is not properly seated on the CPU

Question 4

A user reports that their smartphone's battery drains significantly faster than usual, and the device feels warm to the touch even when it is not being actively used. The battery is not swollen. Which of the following is the MOST likely cause of these symptoms?

Accepted Answer

Background app malfunction causing high CPU usage. A background app malfunction causing high CPU usage forces the processor to draw more power, generating excess heat even when the device is idle. This directly explains both the rapid battery drain and the warmth, as the CPU remains active without user interaction.

Answer

Faulty charging port

Answer

Defective display assembly

Answer

Weak cellular signal

Question 5

A user reports that their wired desktop computer loses network connectivity intermittently. The technician notices that the link light on the network interface card (NIC) turns off when the computer's CPU is under heavy load, such as during video rendering. The technician has already updated the network driver and replaced the Ethernet cable with a known-good cable. The switch port is active and works with other devices. Which of the following is the MOST likely cause of this issue?

Accepted Answer

Power supply unit (PSU) is failing to provide adequate power to the NIC under load. When the CPU is under heavy load, the system draws more power from the PSU. If the PSU is failing or underrated, it may not deliver stable voltage to the NIC, causing the NIC to reset or lose link. This explains why the link light turns off specifically during video rendering, not during idle or light use.

Answer

Faulty switch port

Answer

Network congestion

Answer

Incorrect duplex settings

Question 6

A technician is troubleshooting a desktop computer that powers on for about one second and then shuts down. The technician has already removed all expansion cards and disconnected all drives. The system still exhibits the same behavior with only the CPU, motherboard, one RAM stick, and power supply connected. Which of the following is the MOST likely cause?

Accepted Answer

An incorrectly installed motherboard standoff causing a short circuit.. The symptom of powering on for about one second and then shutting down, even with only the CPU, motherboard, one RAM stick, and power supply connected, strongly indicates a short circuit. An incorrectly installed motherboard standoff that contacts the motherboard's traces or solder points can create a direct short to ground, triggering the power supply's overcurrent protection (OCP) and causing an immediate shutdown. This behavior persists regardless of other components because the short is on the motherboard itself.

Answer

A faulty CMOS battery.

Answer

Incompatible RAM speed.

Answer

Overheating CPU due to improper thermal paste application.

Question 7

A small office has a router that provides DHCP services. Several users report that they cannot access the internet, but they can still access shared folders on the local network. The technician checks one user's computer and sees an IP address of 169.254.10.25. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The DHCP server is not responding. The IP address 169.254.10.25 falls within the Automatic Private IP Addressing (APIPA) range (169.254.0.0/16), which Windows assigns when a DHCP discovery broadcast fails to receive a response. Since users can still access local shared folders, local link-layer connectivity is intact, but the lack of a valid DHCP lease means they have no default gateway or DNS server configuration, preventing internet access. The most likely cause is that the DHCP server (the router) is not responding to DHCP requests.

Answer

The DNS server is not resolving domain names

Answer

The default gateway is misconfigured

Answer

A duplicate IP address exists on the network

Question 8

A systems administrator needs to run multiple virtual machines on a single physical server for a high-performance computing workload. The administrator requires the lowest possible overhead and direct access to hardware resources such as the CPU and memory. Which of the following should the administrator install on the server?

Accepted Answer

A Type 1 hypervisor such as VMware ESXi. A Type 1 hypervisor (bare-metal) like VMware ESXi runs directly on the server hardware without a host OS, providing the lowest possible overhead and direct access to CPU and memory resources. This is essential for high-performance computing workloads where minimal latency and maximum hardware utilization are required.

Answer

A Type 2 hypervisor such as VirtualBox

Answer

A containerization platform such as Docker

Answer

An emulation software such as QEMU without KVM

Question 9

A small office has a router serving as the DHCP and DNS server. All workstations can access the internet but cannot connect to a local file server using its hostname (\fileserver). They can successfully ping the file server's IP address (192.168.1.10). The technician has verified that the file server is powered on and sharing folders. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The router's DNS server does not have a record for the file server's hostname.. The router is serving as the DNS server for the network. Since workstations can ping the file server by IP but not by hostname, the issue is that the DNS server lacks an A (or AAAA) record mapping the hostname 'fileserver' to its IP address 192.168.1.10. Without this record, name resolution fails, even though the server is reachable via IP.

Answer

The DHCP lease on the file server has expired.

Answer

The Windows Firewall on the file server is blocking incoming connections.

Answer

The workstations and file server are in different workgroups.

Question 10

A company uses a public cloud provider to host a critical database. The provider automatically replicates the data across multiple geographic regions to ensure data durability and availability. The company does not need to manage the underlying servers or storage infrastructure. Which cloud characteristic does this configuration BEST demonstrate?

Accepted Answer

High availability. The configuration demonstrates high availability because the cloud provider automatically replicates the critical database across multiple geographic regions, ensuring that if one region fails, the database remains accessible from another region. This redundancy minimizes downtime and data loss without requiring the company to manage the underlying infrastructure, which is the core purpose of high availability in cloud computing.

Answer

On-demand self-service

Answer

Rapid elasticity

Answer

Resource pooling

Question 11

A company is migrating its large collection of user-uploaded photos and videos to a cloud service. The data is unstructured, accessed infrequently, and must be available via HTTP/HTTPS URLs. The IT administrator wants the most cost-effective storage solution that scales automatically without provisioning capacity in advance. Which cloud storage type should the administrator choose?

Accepted Answer

Object storage. Object storage is the correct choice because it is designed for unstructured data like photos and videos, accessed infrequently, and provides HTTP/HTTPS access via RESTful APIs. It scales automatically without requiring capacity provisioning, and its pay-as-you-go model makes it the most cost-effective for this use case.

Answer

Block storage

Answer

File storage

Answer

Hot storage tier

Question 12

A user reports that their Android smartphone's screen remains black during phone calls, even when the phone is held away from the ear. The screen works normally at all other times. The technician has already cleaned the top of the phone where the sensors are located and verified that the screen protector is not obstructing anything. Which of the following components is MOST likely causing the issue?

Accepted Answer

Stuck or faulty proximity sensor. The proximity sensor is designed to detect when the phone is held to the ear and turn off the display to prevent accidental touches. If the sensor is stuck or faulty, it may continuously signal that the phone is against the ear, keeping the screen black even when held away. Cleaning the sensor and checking the screen protector are standard first steps, but if the issue persists, a defective proximity sensor is the most likely cause.

Answer

Failed ambient light sensor

Answer

Corrupted display driver

Answer

Battery saver mode enabled

Question 13

A user reports that they can access internal network resources by IP address but cannot browse the internet by domain name (e.g., www.google.com). The technician checks the workstation's network adapter settings and sees that the IP address is obtained via DHCP. Which of the following is the MOST likely cause of this issue?

Accepted Answer

DNS server configuration. The user can access internal resources by IP address but not by domain name, which indicates that name resolution is failing. Since the workstation obtains its IP address via DHCP, the DNS server configuration is likely missing or incorrect, preventing the system from translating domain names like www.google.com into IP addresses.

Answer

Incorrect subnet mask

Answer

Wrong default gateway

Answer

Duplicate IP address

Question 14

A user reports that their Android smartphone charges very slowly when connected to a laptop's USB-C port that supports Power Delivery. The same cable and charger charge the phone quickly when plugged into a wall outlet. The cable is known to be in good condition. Which of the following is the MOST likely cause of the slow charging?

Accepted Answer

The laptop is in battery saving mode, limiting USB power output. When a laptop is in battery saving mode, it often restricts the power output from its USB ports to conserve energy, even if the port supports Power Delivery (PD). This limitation reduces the current available to the smartphone, resulting in slow charging despite the cable and charger being capable of fast charging when connected to a wall outlet.

Answer

The smartphone's USB-C port is damaged

Answer

The cable is not rated for Power Delivery

Answer

The laptop's USB drivers are outdated

Question 15

A user reports that their laptop cannot detect any wireless networks. The technician sees that the Wi-Fi adapter is enabled in the device manager and has no errors. The laptop has a physical wireless switch on the front edge and a function key (Fn) combination to toggle Wi-Fi. Which of the following should the technician check FIRST?

Accepted Answer

Whether the physical wireless switch is in the ON position. The physical wireless switch is a hardware-level cutoff that can completely disable the Wi-Fi radio, regardless of driver or software settings. Since the adapter shows as enabled in Device Manager with no errors, the most likely cause is that the switch is in the OFF position, which prevents the radio from scanning for networks. Checking this is the fastest and simplest first step before moving to software or driver troubleshooting.

Answer

Whether the network driver needs to be updated

Answer

Whether the Windows Firewall is blocking network discovery

Answer

Whether the antenna cables are connected to the wireless card
