In a scenario where an organization wants to quickly test a new application in a cost-effective manner without concerns for initial infrastructure investments, which cloud model is more appropriate?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
Public Cloud is the best choice for quickly testing new applications with minimal upfront costs. It provides scalable resources and doesn't require organizations to invest heavily in infrastructure. Private clouds are more suited for long-term, controlled environments.
Which cloud model often involves shared resources and benefits from economies of scale?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
Public Clouds are shared environments where resources are pooled, leading to economies of scale. They're accessible to the general public and often cost-effective.
A software development company is in need of a cloud service where they can develop, run, and manage applications without the complexity of building and maintaining the infrastructure. Which essential characteristic of cloud computing would address their requirement?
- Elasticity
- Redundancy
- Scalability
- Self-Service On-Demand
Self-Service On-Demand is a fundamental cloud characteristic that allows developers to provision resources as needed, removing the need for infrastructure management.
An organization is looking to consolidate their server infrastructure to optimize resource usage and reduce costs. By implementing which type of virtualization can they achieve this?
- Application Virtualization
- Network Virtualization
- Server Virtualization
- Storage Virtualization
Server virtualization is the ideal choice for consolidating server resources, enabling multiple VMs on a single physical server, optimizing resource usage, and reducing costs.
In a hybrid cloud model, the mechanism that ensures seamless data and application portability between private and public clouds is called ________.
- Cloud Federation
- Cloud Integration
- Cloud Interoperability
- Cloud Synchronization
Cloud Federation ensures that data and applications can move seamlessly between private and public clouds. It allows for unified management and data transfer between different cloud environments in a hybrid setup.
In which service model is the underlying server, storage, and network infrastructure managed by the cloud provider?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Infrastructure as a Service (IaaS) is the service model where the cloud provider manages the underlying infrastructure, including servers, storage, and networking. Users have control over the operating system, applications, and data, while the cloud provider handles the hardware and data center operations.
In Kubernetes, which component is responsible for scheduling pods onto nodes?
- Kube-Proxy
- Kubelet
- Kubernetes Controller Manager
- Kubernetes Scheduler
The Kubernetes Scheduler is responsible for deciding which nodes to run new pods on based on resource requirements, node availability, and various policies.
Which tool is commonly used for monitoring applications and infrastructure in the AWS cloud environment?
- AWS Lambda
- AWS RDS
- Amazon CloudWatch
- Amazon S3
Amazon CloudWatch is a commonly used tool in AWS for monitoring various aspects of applications and infrastructure within the cloud environment.
A company recently discovered that an unauthorized user accessed its cloud storage and modified sensitive data. Upon investigation, it was found that the attacker used valid login credentials of an employee. This situation is most likely a case of:
- Cross-Site Scripting (XSS) Vulnerability
- Distributed Denial of Service
- Insider Threat
- Man-in-the-Middle (MitM) Attack
This scenario most likely represents an insider threat, where a trusted insider misuses their access privileges to harm the organization, in this case, by modifying data.
A company notices that their cloud bill has spiked significantly in the last month. They decide to use a tool to break down the costs and find anomalies. Which type of tool are they likely to use?
- Cloud Cost Analysis Tool
- Performance Monitoring
- Security Vulnerability Scanner
- Version Control System
A Cloud Cost Analysis Tool is designed to track and analyze cloud spending, helping organizations identify cost anomalies and optimize cloud expenses. It provides insights into how resources are being utilized and where cost-saving opportunities exist.
