A software development team needs to test their application on multiple operating systems without investing in multiple physical machines. How can virtualization assist in this scenario?
- Virtualization allows for OS isolation
- Virtualization enables VM snapshots
- Virtualization provides enhanced security
- Virtualization reduces power consumption
Virtualization assists by allowing developers to create snapshots of VMs, making it easy to test applications on multiple OSs without the need for physical hardware. This enhances testing efficiency.
A company is developing a stock trading platform where real-time data and quick response times are crucial. They need a middleware solution that can handle high-speed messaging and ensure data integrity. Which middleware type would be most appropriate?
- Message Queues
- Publish-Subscribe
- Remote Procedure Calls
- WebSockets
In this context, WebSockets would be most appropriate for real-time, high-speed messaging in stock trading due to their low overhead and bidirectional communication.
Which security measure is essential in preventing account hijacking in cloud environments?
- Encryption
- Intrusion Detection
- Multi-Factor Authentication (MFA)
- Network Segmentation
Multi-Factor Authentication (MFA) is a crucial security measure that requires users to provide multiple forms of verification, significantly reducing the risk of account hijacking. It enhances security beyond passwords.

Azure Functions can be triggered by which of the following events?
- HTTP requests
- File changes
- Temperature variations
- Brainwave patterns
Azure Functions can be triggered by HTTP requests. These requests are often used to create RESTful APIs, webhooks, and other HTTP-triggered functions. The other options are unrelated to Azure Functions.
In a cloud environment, computational power, storage, and network capabilities are examples of:
- Data as a Service (DaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Computational power, storage, and network capabilities are part of Infrastructure as a Service (IaaS) in cloud computing, providing essential infrastructure resources.
What is the primary role of a hypervisor in virtualization?
- Allocating memory for VMs
- Managing hardware resources for virtual machines
- Providing a user-friendly interface for VM management
- Securing data within virtual machines
The primary role of a hypervisor in virtualization is to manage and allocate hardware resources, such as CPU, memory, and storage, among virtual machines to ensure efficient and isolated operation.

Process is a type of virtualization that allows multiple instances of an application to run concurrently on a single OS, without interfering with each other.
- Application
- Network
- Server
- Storage
Process virtualization allows multiple instances of an application to run without conflicts on a single operating system. This is often used in server environments.
Which of the following is a security method that translates data into a code to prevent unauthorized access?
- Compression
- Duplication
- Encryption
- Fragmentation
Encryption is a security method that translates data into a code to prevent unauthorized access. It makes the data unreadable without the correct decryption key, enhancing data security.
