How to use 220-1101 flashcards effectively
Flashcards work through active recall — the process of retrieving information from memory rather than passively re-reading it. Research consistently shows that active recall produces stronger, longer-lasting memory than re-reading study guides. For 220-1101 preparation, this means flashcards are one of the highest-return study tools available.
Attempt recall first
Read the 220-1101 question on each card, pause, and attempt to formulate the answer in your own words before revealing. This retrieval attempt — even if wrong — dramatically strengthens memory compared to immediately reading the answer.
Review wrong cards again
When you get a card wrong, note it and add it back to your review pile. Spaced repetition — seeing difficult cards more frequently — is the mechanism that makes flashcard study far more efficient than linear reading.
Study by domain
Group your 220-1101 flashcard sessions by domain for the first 3–4 weeks. Master one domain before moving to the next. In the final week, shuffle all cards together to test cross-domain recall — which is what the real 220-1101 exam requires.
Short sessions beat marathon reviews
20–30 flashcard cards per session, done daily, produces better retention than a single 200-card marathon session. Five short daily sessions per week over 4 weeks gives you over 400 total card reviews — enough to reliably pass 220-1101.

Sample cards from the 220-1101 flashcard bank. Read the question, think of the answer, then read the explanation below.
A user reports that the touchscreen on their smartphone is unresponsive in the bottom-left corner but works everywhere else. Which component is most likely failing?
Digitizer failure
The touchscreen uses a digitizer to detect touch input. When only certain areas are unresponsive, it typically indicates a digitizer failure rather than an LCD or OS issue. Dead pixels affect display only, not touch. The backlight affects overall screen brightness. An OS update might cause temporary glitches but would not result in a localized dead zone.
A technician is adding a wireless access point (AP) in an outbuilding connected via Ethernet to the main office network (192.168.1.0/24). After configuring the AP with a static IP of 192.168.1.250, clients can connect to Wi-Fi but cannot access the internet. The main office devices have no issues. What is the most likely cause?
The new AP has its DHCP server enabled
When an access point has its router functionality or DHCP server enabled, it can assign IP addresses from a different subnet or conflict with the existing DHCP server, breaking internet connectivity. Disabling the DHCP server on the AP and ensuring it is in bridge mode resolves the issue.
A technician is assembling a workstation for video editing. The motherboard has two DIMM slots and supports dual-channel DDR4-3200 memory. The user requests 32 GB of RAM. Which memory configuration will provide the best performance?
Two 16 GB DDR4-3200 modules
Dual-channel architecture benefits from matching modules in both slots. Using two identical DDR4-3200 sticks ensures maximum bandwidth and speed. Single-channel or mismatched speeds will reduce performance, especially in memory-intensive tasks like video editing.
A company wants to migrate its on-premises email server to the cloud. The IT director insists that the new solution require no management of the underlying operating system, application server, or patching. Which cloud service model should the organization choose?
Software as a Service (SaaS)
SaaS provides fully managed applications delivered over the internet. The customer focuses on using the software while the provider handles all infrastructure, OS, and application maintenance. This matches the requirement of zero OS or patching management.
After a power outage, a desktop computer will not power on. The PSU fan does not spin, and no LEDs are lit. The technician tests the power supply with a PSU tester; all voltages are within spec. A multimeter reading at the motherboard's power button header shows 3.3V when the button is pressed. The power supply is also confirmed to work when tested in another system. What is the most likely cause?
The motherboard has failed
The PSU is functional (confirmed by tester and working in another system). The power switch circuit is producing the correct signal (3.3V). This points to a motherboard failure, likely the power regulation circuitry or the chipset responsible for initiating the power-up sequence. A failed motherboard cannot properly process the power-on signal to start the PSU.
A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?
Electromagnetic interference from the case fan
Electromagnetic interference (EMI) from the case fan, especially when running at high speed, can disrupt the signal integrity of an unshielded Ethernet cable or interfere with the NIC circuitry. This can cause the link to drop temporarily. The fact that the issue correlates with fan speed points strongly to EMI. A faulty NIC would likely be persistent, not correlation with fan speed. Cable pinning is unlikely because the cable passed the wiremap test. Driver conflict is less likely because the driver is updated and the issue is tied to fan operation.
A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
The switch port is assigned to VLAN 10, while the default gateway exists on VLAN 20, preventing connectivity without proper inter-VLAN routing.
The workstation is assigned to VLAN 10 via the switch port configuration, but the default gateway is on a different VLAN (20). Without proper inter-VLAN routing (e.g., a router-on-a-stick with ACLs permitting traffic between VLANs), devices in VLAN 10 cannot reach the gateway on VLAN 20. The DHCP server provided an IP within VLAN 10's subnet, which is correct for that VLAN, but the gateway is in another subnet. The switch port VLAN assignment is the root cause; it should be on VLAN 20 to match the gateway, or inter-VLAN routing must be configured correctly.
A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?
Infrastructure as a Service (IaaS)
This scenario requires a balance between control and reduced overhead. Infrastructure as a Service (IaaS) provides virtual machines where the user manages the operating system and software, while the cloud provider handles the underlying hardware. This allows full control over the software stack. PaaS would typically abstract away the OS and restrict customization, while SaaS delivers a fully managed application. FaaS (serverless) offers even less control over the runtime environment.
A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?
Export the VM as an OVF template and import it into the new hypervisor.
The Open Virtualization Format (OVF) is a standard for packaging virtual machines, enabling migration between different hypervisors. Exporting the VM as an OVF template from Hyper-V and importing it into VMware vSphere preserves the VM's state and is designed for cross-hypervisor migrations. Physical-to-virtual (P2V) conversion (A) is for physical servers, not VMs. Live migration (vMotion) (C) only works between VMware hosts, not cross-hypervisor. Rebuilding from scratch (D) involves significant downtime and reconfiguration, not minimal downtime.
A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?
File storage
File storage (such as Amazon EFS or Azure Files) provides a shared filesystem that can be mounted by multiple VMs simultaneously and persists independently of any single VM. Block storage (like Amazon EBS) is persistent but is typically attached to one VM at a time (multi-attach is limited). Object storage (like Amazon S3) is also persistent but is accessed via API, not as a block device or filesystem, and is not ideal for direct database use. Ephemeral storage is lost when the VM is terminated.
A cloud administrator needs to increase the amount of RAM allocated to a running virtual machine (VM) from 4GB to 8GB to handle a temporary workload spike. The administrator logs into the cloud management console, selects the VM, and changes the instance type to one with 8GB of RAM. The change takes effect immediately without requiring a reboot. Which cloud computing characteristic does this scenario BEST illustrate?
Rapid elasticity
Rapid elasticity is the ability to quickly scale resources up or down, often automatically, and in some cases without downtime. While this action also demonstrates on-demand self-service (the administrator performed it themselves), the core concept being illustrated is the rapid and flexible scaling of resources (elasticity). Measured service relates to metering and billing. Resource pooling refers to multi-tenant sharing. The immediate adjustment of resources without rebooting highlights the elastic nature of cloud computing.
A company hosts a legacy application on a virtual machine. The application's license is tied to the MAC address of the virtual machine's network interface. The administrator needs to migrate the VM to a different host server without breaking the license. Which of the following virtualization features should the administrator use?
MAC address cloning/static assignment
Most hypervisors allow setting a static or custom MAC address for a virtual NIC, rather than using the automatically generated one. By configuring the VM's network adapter to use the same MAC address after migration, the licensing software will see the same identifier and continue to work. Features like VLAN tagging, jumbo frames, and network bonding do not affect the MAC address seen by the application.
A company hosts a critical web application using a public cloud provider. The application is deployed across two separate data centers in different geographic regions. The cloud provider automatically routes traffic to the healthy region in the event of a full data center outage, with no manual intervention. Which cloud computing characteristic does this BEST describe?
High availability
High availability (HA) refers to systems that are designed to remain operational with minimal downtime through redundancy and automatic failover. In this scenario, the automatic routing of traffic to a healthy region during a data center outage is a classic example of HA. Fault tolerance (option D) is sometimes used interchangeably but typically implies continuous operation with no interruption even during a failure, often requiring redundant components that are always active. Elasticity (A) is the ability to scale resources up/down automatically based on demand. Scalability (C) is the ability to increase resources to handle growth but does not inherently include automatic failover.
A company implements a private cloud where multiple departments share the same physical hardware. The cloud platform ensures that each department's virtual machines are isolated from each other and that resources are dynamically allocated based on demand. Which cloud characteristic BEST describes this arrangement?
Resource pooling
Resource pooling allows a cloud provider to serve multiple consumers using a multi-tenant model, with physical and virtual resources dynamically assigned according to consumer demand. The isolation between departments' workloads is a key aspect of resource pooling. Rapid elasticity refers to the ability to scale resources quickly, which is not the primary focus of this scenario. Measured service is about metering and optimizing resource usage. On-demand self-service allows users to provision resources without human interaction, which is implied but not the main characteristic described.
A company hosts a critical web application on a public cloud provider. The architecture uses virtual server instances in two geographically separate data centers (regions). A global load balancer monitors the health of each region and distributes incoming user traffic. If an entire region becomes unavailable due to a natural disaster, the load balancer automatically redirects all traffic to the remaining healthy region. This design is intended to meet a specific business requirement. Which cloud characteristic does this architecture BEST demonstrate?
High availability
This architecture is designed to maintain application accessibility even when a major component (an entire region) fails. This is the definition of high availability. High availability ensures minimal downtime by eliminating single points of failure and using failover mechanisms. Elasticity refers to scaling resources up or down based on demand; this scenario does not involve scaling. Resource pooling describes the provider's ability to serve multiple customers with shared physical resources. Measured service is the pay-per-use metering model. Therefore, high availability is the correct characteristic.
A company hosts its e-commerce website on a public cloud platform. During the holiday shopping season, traffic increases dramatically. The cloud platform automatically adds more virtual server instances to handle the increased load and then removes them when traffic returns to normal. Which cloud computing characteristic does this scenario BEST describe?
Rapid elasticity
Rapid elasticity is the cloud characteristic that allows resources to be automatically and quickly scaled out (added) during periods of high demand and scaled in (removed) when demand decreases. This is a key benefit of cloud computing, enabling cost efficiency and performance without manual intervention. On-demand self-service refers to users provisioning resources without human interaction. Measured service involves monitoring and reporting usage. Resource pooling means multiple customers share the same physical infrastructure.
A company must run a sensitive financial application that requires the application to be hosted on physical servers that are not shared with any other customer. The workload is highly variable and may require large amounts of resources for a few hours at a time. The company wants to minimize costs by paying only for the resources consumed. Which of the following cloud deployment models BEST meets these requirements?
Public cloud with dedicated hosts
A public cloud offering with dedicated hosts provides exclusive physical servers to a single customer. These hosts can be provisioned on demand and billed per use (pay-as-you-go), allowing the company to handle variable workloads without long-term commitment. A private cloud would require the company to own and manage its own infrastructure, which is not cost-effective for variable usage and does not provide true pay-per-use. A hybrid cloud mixes public and private, but the dedicated server requirement points to a hosted dedicated solution. A community cloud is shared among several organizations and does not guarantee exclusive hardware.
A company hosts a production database on a public cloud IaaS platform. The database requires consistent low-latency access to a storage volume that can be attached to a single virtual machine. The volume must persist independently of the VM's lifecycle, meaning data should remain intact even if the VM is stopped and started. The workload requires up to 10,000 IOPS. Which of the following cloud storage types should the technician configure to meet these requirements?
C
Block storage (such as Amazon EBS) provides persistent, high-performance storage volumes that can be attached to a single VM. It offers configurable IOPS levels and data persists after the VM is stopped. Object storage (A) is designed for unstructured data and accessed via API, not as a block device. Instance store (B) is ephemeral storage tied to the VM's lifecycle; data is lost when the VM is stopped or terminated. Network File System (D) is a file-level protocol that typically has higher latency and is shared among multiple VMs, not ideal for low-latency database storage requiring high IOPS.
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?
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides virtualized computing resources (VMs, storage, networking) where the customer manages the OS, middleware, and applications. In this scenario, the company manages the OS and Exchange application; the provider maintains physical hardware and hypervisor. PaaS would abstract the OS and require the customer to only deploy code. SaaS provides a ready-to-use application. DaaS delivers desktops, not servers.
A company subscribes to a cloud service that allows them to select a set amount of virtual CPU cores, RAM, and storage for their instances. They are billed monthly based on the total resources used, regardless of how many times they change the configuration. This billing model BEST represents which cloud computing characteristic?
Measured service
Measured service is the cloud characteristic where resource usage is metered and billed according to consumption. In this scenario, the company pays based on the total resources used, which aligns directly with measured service. On-demand self-service allows users to provision resources without human interaction, but does not specifically address billing. Rapid elasticity refers to the ability to scale resources quickly up and down, not the billing method. Resource pooling describes the provider's multi-tenant model where resources are shared among customers.
A business uses a cloud service that automatically increases the number of virtual servers during peak traffic hours and decreases them during low usage, all without manual intervention. The policy is predefined in the cloud management console. This scenario best exemplifies which characteristic of cloud computing?
Rapid elasticity
Rapid elasticity is the cloud characteristic that allows resources to scale quickly outward and inward based on demand, often automatically. This enables users to seamlessly handle variable workloads without manual provisioning. The other options describe different cloud attributes: on-demand self-service, resource pooling, and measured service.
A company hosts a critical application on a public cloud provider. The solution is designed with a set of pre-configured virtual machines that are kept powered off in a different availability zone. In the event of a failure in the primary zone, the standby VMs are automatically started, and traffic is rerouted. This design primarily addresses which of the following cloud computing characteristics?
Disaster recovery
Disaster recovery (DR) involves replicating data and systems to a secondary site and activating them after a disaster. In this scenario, the standby VMs are powered off and started only when needed, which is typical of a cold standby DR solution. High availability (HA) implies immediate failover with no downtime, often using active-active or hot standby configurations. Fault tolerance means the system continues to operate without interruption despite component failures. Scalability is about adjusting resources to handle varying load. Therefore, the correct answer is disaster recovery.
A cloud administrator can log into a web portal at any time, day or night, and immediately provision a new virtual server with the desired resources without having to contact the cloud provider's support team or wait for approval. Which essential characteristic of cloud computing does this scenario BEST describe?
On-demand self-service
On-demand self-service is one of the five essential characteristics of cloud computing as defined by NIST. It allows users to provision computing resources (e.g., server time, network storage) automatically as needed without requiring human interaction with service providers. This contrasts with traditional IT where provisioning could take days or weeks. Broad network access refers to accessibility over the network via standard protocols. Resource pooling means the provider's resources serve multiple customers. Measured service involves metering and billing for consumption.

Flashcards vs practice tests: which is better for 220-1101?
Both flashcards and practice questions are evidence-based study tools. The difference is in what they train:
Flashcards — concept retention
Best for memorising definitions, acronyms, protocol behaviours, command syntax, and conceptual distinctions. Use flashcards to build the foundational vocabulary that 220-1101 questions assume you know.
Best in: weeks 1–3
Practice tests — application
Best for applying concepts to realistic scenarios, eliminating distractors, and building exam stamina.220-1101 questions test scenario reasoning — not just recall — so practice tests are essential.
Best in: weeks 3–6
The most effective 220-1101 study plan combines both: use flashcards for the first 2–3 weeks to build conceptual foundations, then shift to practice tests and mock exams in the final 2–3 weeks to apply and benchmark that knowledge. Most candidates who pass on their first attempt use both tools.
