Cognizant GenC Technical Assessment- Cloud Fundamental MCQs – Set 5
1. Which cloud deployment model is best suited for an organization requiring complete control over its infrastructure?
Correct Answer: b) Private Cloud
Explanation: A private cloud offers dedicated infrastructure to a single organization, providing complete control over security, customization, and management. Public clouds (option a) are shared, hybrid clouds (option c) combine public and private elements, and community clouds (option d) are shared among organizations with similar needs, none of which offer the same level of control as a private cloud.
2. What is the primary function of a cloud load balancer?
Correct Answer: b) To distribute network traffic across multiple servers
Explanation: A cloud load balancer distributes incoming network traffic across multiple servers to ensure no single server becomes overwhelmed, improving performance and reliability. Option a refers to storage services, option c relates to security mechanisms like SSL/TLS, and option d pertains to monitoring tools, none of which are the primary function of a load balancer.
3. Which of the following is a characteristic of IaaS?
Correct Answer: b) The user manages the operating system and server software
Explanation: In IaaS (Infrastructure as a Service), the provider manages the hardware and virtualization, while the user is responsible for the operating system, server software, and applications. Option a describes PaaS, option c applies to SaaS, and option d contradicts the control IaaS provides to users over the infrastructure.
4. What is the purpose of a Virtual Private Cloud (VPC)?
Correct Answer: b) To create an isolated network environment within a public cloud
Explanation: A Virtual Private Cloud (VPC) allows users to create a logically isolated network within a public cloud, enhancing security and control over resources. Option a contradicts the private nature of a VPC, option c is incorrect as VPCs enhance security, and option d is false since VPCs do not limit scalability but provide flexibility within the cloud.
5. Which AWS service is used for managing containerized applications?
Correct Answer: b) Amazon ECS
Explanation: Amazon ECS (Elastic Container Service) is AWS’s service for managing and orchestrating containerized applications using Docker. AWS Lambda (option a) is for serverless computing, Amazon S3 (option c) is for storage, and AWS CloudFormation (option d) is for infrastructure as code, none of which manage containers directly.
6. What does “elasticity” refer to in the context of cloud computing?
Correct Answer: b) The ability to automatically scale resources up or down as needed
Explanation: Elasticity in cloud computing refers to the system’s ability to automatically scale resources up or down based on demand, ensuring efficiency and cost-effectiveness. Option a refers to manual scaling, not elasticity, while options c and d do not align with the concept of elasticity, which focuses on adaptability, not cost reduction or limitation.
7. Which of the following is a benefit of cloud bursting?
Correct Answer: b) Handling sudden spikes in demand by using public cloud resources
Explanation: Cloud bursting allows a private cloud to temporarily use public cloud resources to handle sudden demand spikes, ensuring performance. Option a is incorrect as cloud bursting enhances scalability, option c is false as it aims to maintain performance, and option d is inaccurate since costs are only higher during bursts, not for all workloads.
8. What is a key advantage of using Infrastructure as Code (IaC)?
Correct Answer: b) Automated and consistent infrastructure provisioning
Explanation: Infrastructure as Code (IaC) allows users to define infrastructure using code, enabling automated, consistent, and repeatable provisioning. Option a contradicts IaC’s automation, option c is false as IaC can improve security through consistency, and option d is incorrect since IaC supports scalability by simplifying resource management.
9. Which Google Cloud service is equivalent to AWS S3 for object storage?
Correct Answer: b) Google Cloud Storage
Explanation: Google Cloud Storage is Google Cloud’s object storage service, equivalent to AWS S3, used for storing unstructured data. Google Compute Engine (option a) is for virtual machines, Google App Engine (option c) is a PaaS for applications, and Google BigQuery (option d) is for data analytics, none of which are object storage services.
10. What is the primary goal of cloud disaster recovery?
Correct Answer: b) To ensure business continuity in case of failures
Explanation: Cloud disaster recovery aims to ensure business continuity by enabling quick recovery of data and applications after failures like outages or cyberattacks. Option a is incorrect as it aims to minimize costs, option c contradicts the goal of disaster recovery, and option d is false since the focus is on maintaining availability, not reducing it.
