CompTIA CompTIA Cloud Essentials CLO-002 Questions & Answers

• Question 211:

  Which of the following technologies would help a game company prepare its cloud infrastructure to support a global distribution workload of a newly released online game? (Choose two.)

  A. Auto-scaling

  B. VDI

  C. Data portability

  D. CDN

  E. Templates

  F. Blockchain

  Correct Answer: AD

  Explanation: Auto-scaling and CDN are two technologies that would help a game company prepare its cloud infrastructure to support a global distribution workload of a newly released online game. Auto-scaling is the ability of a cloud service to automatically adjust the amount of resources, such as compute, storage, or bandwidth, based on the demand or load of the service. Auto-scaling can help a game company to handle the spikes or fluctuations in the number of players or traffic that may occur during the launch or peak times of a new online game. Auto-scaling can also help the game company to optimize the performance, availability, and cost of the cloud service, as it can scale up or down the resources as needed. Auto-scaling can be triggered by predefined rules, metrics, or schedules, or by using machine learning or artificial intelligence to predict the demand patterns12 CDN stands for Content Delivery Network, which is a network of distributed servers that deliver content, such as web pages, images, videos, or games, to the end-users based on their geographic location, the origin of the content, and the network conditions. CDN can help a game company to distribute its online game to a global audience, as it can reduce the latency, bandwidth, and load on the origin server, and improve the user experience, security, and reliability of the content delivery. CDN can also help the game company to cope with the high volume of requests or traffic that may occur during the launch or peak times of a new online game. CDN can use various techniques, such as caching, compression, encryption, or load balancing, to optimize the content delivery34 References: CompTIA Cloud Essentials+ Certification Exam Objectives5, CompTIA Cloud Essentials+ Study Guide, Chapter 4: Cloud Storage6, Chapter 6: Cloud Connectivity and Load Balancing7

• Question 212:

  A company is moving to the cloud and wants to enhance the provisioning of compute, storage, security, and networking. Which of the following will be leveraged?

  A. Infrastructure as code

  B. Infrastructure templates

  C. Infrastructure orchestration

  D. Infrastructure automation

  Correct Answer: A

  Explanation: Infrastructure as code (IaC) is a DevOps practice that uses code to define and deploy infrastructure, such as networks, virtual machines, load balancers, and connection topologies1. IaC ensures consistency, repeatability, and scalability of the infrastructure, as well as enables automation and orchestration of the provisioning process2. IaC is different from infrastructure templates, which are predefined configurations that can be reused for multiple deployments3. Infrastructure orchestration is the process of coordinating multiple automation tasks to achieve a desired state of the infrastructure4. Infrastructure automation is the broader term for any technique that uses technology to perform infrastructure tasks without human intervention5.

• Question 213:

  The IT department has noticed the costs associated with the server are increasing. The application is scheduled to run uninterrupted for at least two years, and the Chief Financial Officer (CFO) would like the IT department to investigate ways to decrease the costs. Which of the following would MOST likely help to decrease the costs of the server?

  A. Migrate the server to another CSP.

  B. Convert the server to a reserved instance.

  C. Configure resource tagging on the server.

  D. Run the server in a sandbox environment.

  E. Utilize spot instances.

  Correct Answer: B

  Explanation: A reserved instance is a type of cloud instance that offers a discounted hourly rate and capacity reservation for a specific period of time, typically one or three years. Reserved instances are suitable for applications that have predictable usage patterns and require uninterrupted performance. By converting the server to a reserved instance, the IT department can reduce the costs of the server by up to 72%, compared to on-demand instances1. Additionally, reserved instances can provide more stability and availability than spot instances, which are subject to interruption and fluctuating prices.

• Question 214:

  A company has a perpetual license for a database application. Which of the following is the MOST cost- effective option when moving to the cloud?

  A. Fixed

  B. Subscription

  C. EULA

  D. BYOL

  Correct Answer: D

  Explanation: BYOL stands for Bring Your Own License, which is a cloud service model that allows customers to use their existing software licenses when migrating to the cloud. BYOL can help customers to reduce costs, avoid vendor lock-in, and leverage their existing investments in software. BYOL is the most cost-effective option when moving to the cloud for a company that has a perpetual license for a database application, as it does not require paying additional fees for the cloud provider's license or subscription. However, BYOL may have some limitations, such as compatibility, compliance, or support issues, depending on the cloud provider and the software vendor. Therefore, customers should carefully review the terms and conditions of their licenses and the cloud provider's policies before choosing BYOL.

• Question 215:

  Which of the following are considered secure access types of hosts in the cloud? (Choose two.)

  A. HTTPS

  B. HTTP

  C. SSH

  D. Telnet

  E. RDP

  F. FTP

  Correct Answer: AC

  Explanation: HTTPS and SSH are considered secure access types of hosts in the cloud because they use encryption and authentication to protect the data and the identity of the users. HTTPS is a protocol that uses SSL or TLS to encrypt the

  communication between a web browser and a web server. SSH is a protocol that allows secure remote login and file transfer over a network. Both HTTPS and SSH prevent unauthorized access, eavesdropping, and tampering of the data in

  transit. References: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (LO-002), Chapter 3:

  Security in the Cloud, pages 83-84.

• Question 216:

  A business analyst is examining a report and notices compute costs are very high for four cloud-based, load- balanced virtual machines hosting an application. The application will be in use for at least two more years, but there are no developers available to help optimize it. Which of the following should the analyst recommend to BEST reduce costs without impacting performance?

  A. Decommission a virtual machine.

  B. Change to a pay-as-you-go plan.

  C. Convert the application to a SaaS solution.

  D. Switch the virtual machines to reserved instances.

  Correct Answer: D

  Explanation: Reserved instances are a discount billing concept in which businesses can obtain significant discounts compared to standard on-demand cloud computing prices in return for committing to a specified level of usage1. Reserved instances are not physical instances, but rather a billing discount applied to the use of on-demand instances in the account2. Reserved instances can save up to 75% over equivalent on-demand capacity3. By switching the virtual machines to reserved instances, the analyst can best reduce costs without impacting performance, as long as the application's usage pattern is predictable and consistent. Decommissioning a virtual machine might affect the performance and availability of the application. Changing to a pay-as-you-go plan might not reduce costs if the application's usage is high and stable. Converting the application to a SaaS solution might require additional development and migration efforts, which are not feasible in this scenario. References:

• Question 217:

  Which of the following is a benefit of microservice applications in a cloud environment?

  A. Microservices are dependent on external shared databases found on cloud solutions.

  B. Federation is a mandatory component for an optimized microservice deployment.

  C. The architecture of microservice applications allows the use of auto-scaling.

  D. Microservice applications use orchestration solutions to update components in each service.

  Correct Answer: C

  Explanation: Microservice applications are composed of many smaller, loosely coupled, and independently deployable services, each with its own responsibility and technology stack1. One of the benefits of microservice applications in a cloud environment is that they can use auto-scaling, which is the ability to automatically adjust the amount of computing resources allocated to a service based on the current demand2. Auto-scaling can help improve the performance, availability, and cost-efficiency of microservice applications, as it allows each service to scale up or down according to its own needs, without affecting the rest of the application2. Auto-scaling can also help handle unpredictable or variable workloads, such as spikes in traffic or seasonal fluctuations2. Auto-scaling can be implemented using different cloud services, such as Google Kubernetes Engine (GKE) or Cloud Run, which provide both horizontal and vertical scaling options for microservice applications34.

• Question 218:

  A company is planning to integrate the processes of several applications and assign a manager to oversee the technical coordination to improve efficiency. Which of the following would be BEST for coordinating the processes?

  A. Orchestration

  B. Scripting

  C. Continuous integration

  D. Continuous delivery

  Correct Answer: A

  Explanation: Orchestration is the best option for coordinating the processes of several applications and assigning a manager to oversee the technical coordination to improve efficiency. Orchestration is the combined automation of apps, workloads, supporting resources, and infrastructure across one or more cloud platforms1. It commonly includes imperative and/or declarative methods to drive automation1. Orchestration introduces and enforces a workflow for automated activities of various processes to deliver the desired service to its client2. Orchestration helps IT organizations reduce manual, repetitive work, better standardize their deployments and operations, and accelerate delivery1. Orchestration also enables businesses to easily add or remove computing resources, on demand, without significant hardware investment or infrastructure changes2. Orchestration ensures that businesses can efficiently and seamlessly handle varying workloads, optimize resource utilization, and enhance the overall reliability and performance of cloud computing systems3. Orchestration is different from the other options listed in the question, which are not directly related to coordinating the processes of several applications. Scripting is the use of code to perform a specific task or operation on a single component of an application, workload, resource, or infrastructure within a cloud platform1. Scripting is one of the building blocks for delivering cloud orchestration, but it does not provide the coordination, arrangement, or end-to-end automation of the deployment of services in a cloud-based environment2. Continuous integration is the practice of merging code changes from multiple developers into a shared repository frequently, usually several times a day, to detect and resolve errors early4. Continuous integration is a part of the DevOps methodology, which aims to improve the quality and speed of software delivery, but it does not address the orchestration of the processes of several applications across multiple cloud platforms1. Continuous delivery is the practice of releasing software updates to production in small increments, usually after passing automated tests, to ensure that the software is always in a deployable state4. Continuous delivery is another part of the DevOps methodology, which aims to reduce the risk and cost of software deployment, but it does not address the orchestration of the processes of several applications across multiple cloud platforms1.
