220-1101 Practice Test 13 — 15 Questions

Question 1

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?

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

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 2

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 3

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 4

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 5

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 6

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 7

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 8

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

Question 9

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?

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 10

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 11

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 12

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 13

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 14

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 15

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
