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

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.
An e-commerce platform experiences high traffic surges during sale events. They want to migrate to the cloud efficiently, with minimal downtime. Which strategy would be best for them?
- Cloud Bursting
- Horizontal Scaling
- Serverless Computing (FaaS)
- Vertical Scaling
Cloud bursting is the most suitable strategy for an e-commerce platform with traffic surges. It allows the platform to scale dynamically to the cloud to handle peak loads while minimizing the migration effort.
In the context of AI in the cloud, what does a pre-trained model refer to?
- A model that is trained on new data
- A model that is trained on public data
- A model that requires further training
- A model that was trained by a user
A pre-trained model refers to a machine learning model that has already been trained on a large dataset and is available for use without further training. Typically, these models are trained on publicly available data.
Which type of cloud is made available to the general public by cloud service providers?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A "Public Cloud" is a cloud infrastructure made available to the general public by service providers. It is shared by multiple organizations and is typically accessed over the internet. Public clouds offer scalability and cost-efficiency.
A media company wants to automate the process of video transcoding whenever a new video file is uploaded to their Amazon S3 bucket. Which AWS service would be most suitable for this scenario?
