220-1101 Practice Test 8 — 10 Questions

Question 1

A company wants to allow multiple developers to each have their own isolated environment on a single physical server. Each developer needs full control over their own operating system and the ability to install custom applications. Which technology is BEST suited for this requirement?

Accepted Answer

Virtualization. Virtualization (A) is the best choice because it allows multiple virtual machines (VMs) to run on a single physical server, each with its own full operating system (OS) instance. Each developer gets isolated, full control over their OS and can install custom applications, as the hypervisor (e.g., VMware ESXi, Microsoft Hyper-V) abstracts the hardware and allocates dedicated resources (CPU, RAM, storage) per VM.

Answer

Containerization

Answer

Cloud computing

Answer

Dual boot

Question 2

A company wants to migrate a custom-developed web application to the cloud. The IT team needs full control over the operating system, middleware, and runtime environment but does not want to manage physical hardware or the underlying virtualization layer. Which cloud service model should the organization choose?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, giving the customer full control over the operating system, middleware, and runtime environment while abstracting away the physical hardware and underlying virtualization layer. This matches the requirement for complete control without managing the physical infrastructure.

Answer

Software as a Service (SaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 3

A company hosts a critical web application on a public cloud IaaS platform. The application runs on virtual machines in a single region. The company wants to ensure that the application remains available even if the entire cloud region experiences an outage. They plan to deploy an identical infrastructure in a second region and configure automatic traffic failover. No manual intervention should be required after the failover. Which of the following cloud concepts BEST describes this architecture?

Accepted Answer

High availability. This architecture is best described as high availability because it uses redundant infrastructure in a second region with automatic traffic failover to ensure the application remains accessible during a regional outage. High availability focuses on minimizing downtime by eliminating single points of failure, and the requirement for no manual intervention aligns with an active-passive or active-active HA design using DNS-based or load balancer failover mechanisms.

Answer

Disaster recovery

Answer

Fault tolerance

Answer

Elasticity

Question 4

A company operates a private cloud using a hypervisor cluster. The administrator wants to ensure that if a physical host server fails, the virtual machines running on that host are automatically restarted on other healthy hosts in the cluster with minimal manual intervention. Which hypervisor feature should the administrator configure?

Accepted Answer

High Availability (HA). High Availability (HA) is the correct feature because it automatically detects a physical host failure and restarts the affected virtual machines on other healthy hosts in the cluster without requiring manual intervention. This is achieved through heartbeat monitoring between hosts and a cluster resource management system that ensures VM availability after a host crash.

Answer

Live Migration

Answer

Fault Tolerance

Answer

Resource Pooling

Question 5

A company wants to migrate its on-premises infrastructure to the cloud while retaining full control over network configuration, firewall rules, and security policies. The company does not want to manage physical servers, storage, or the underlying hypervisor. Which cloud service model BEST meets these requirements?

Accepted Answer

IaaS (Infrastructure as a Service). IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet, allowing the company to manage network configurations, firewall rules, and security policies while the cloud provider handles physical servers, storage, and the hypervisor. This model gives the customer control over the operating system, middleware, and applications, but not the underlying physical infrastructure, directly matching the requirement to avoid managing physical hardware.

Answer

SaaS (Software as a Service)

Answer

PaaS (Platform as a Service)

Answer

DaaS (Desktop as a Service)

Question 6

A company runs an internal web application on an on-premises virtual server that handles typical daily traffic. During seasonal sales, traffic spikes to ten times the normal volume. The company configures a public cloud service to automatically deploy additional virtual server instances when the on-premises server reaches a certain utilization threshold. These instances connect to the same database and load balancer, and they are terminated when traffic returns to normal. Which cloud architecture does this describe?

Accepted Answer

Cloud bursting. This scenario describes cloud bursting, a hybrid cloud model where an application runs primarily on-premises but can 'burst' into the public cloud during peak demand. This allows the company to handle traffic spikes without maintaining expensive idle capacity on-premises. Rapid elasticity is a characteristic of cloud computing, but cloud bursting is the specific architectural pattern that combines on-premises and public cloud resources.

Answer

Rapid elasticity

Answer

Resource pooling

Answer

High availability

Question 7

A company runs a critical database server on a virtual machine hosted on a Type 1 hypervisor. The requirement is that the database server must remain operational and accessible even if the underlying physical host experiences a hardware failure. Which of the following virtualization features should be implemented to achieve this goal?

Accepted Answer

Fault tolerance. Fault tolerance (B) is correct because it creates a secondary, shadow virtual machine that runs in lockstep with the primary VM. If the physical host fails, the secondary VM takes over instantly with no data loss or downtime, ensuring the database server remains operational.

Answer

Live migration

Answer

Load balancing

Answer

Snapshot

Question 8

A laser printer produces light ghost images of previously printed text on the following page. The technician has already replaced the toner cartridge and the imaging drum with new OEM components. The fuser appears to be heating properly. Which of the following is the NEXT component the technician should inspect or replace?

Accepted Answer

Primary charge corona / charge roller. The primary charge corona or charge roller is responsible for applying a uniform electrostatic charge to the imaging drum before the laser writes the image. If this component is failing, it may not fully erase the previous charge pattern, leaving residual latent images that develop into ghost images. Replacing the toner cartridge and drum eliminates those as causes, and the fuser is heating properly, so the charge roller is the next likely culprit.

Answer

Transfer roller

Answer

Laser scanner unit

Answer

Erase lamp

Question 9

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 10

A network laser printer is printing pages with garbled characters and random symbols. The technician prints a test page from the printer's control panel, which prints correctly. The technician then prints from a different computer on the same network, and the printout is also garbled. The printer driver has been reinstalled. Which of the following should the technician check NEXT?

Accepted Answer

Change the printer's emulation mode. The correct answer is C because the printer prints correctly from its own test page but produces garbled output from multiple network computers, indicating the issue is with how the print data is interpreted. Changing the printer's emulation mode (e.g., from PCL to PostScript or vice versa) resolves mismatches between the driver's page description language and the printer's interpreter, which is a common cause of garbled characters when the driver reinstall hasn't fixed the problem.

Answer

Replace the network cable

Answer

Update the printer firmware

Answer

Replace the imaging drum
