In cloud computing, the characteristic that allows for pooling of computing resources to serve multiple consumers using a multi-tenant model is called ________.
- Elasticity
- Multi-Tenancy
- Scalability
- Virtualization
Multi-Tenancy is the characteristic that enables multiple consumers to share computing resources in a cloud environment. It enhances resource utilization and cost-effectiveness.
Refactoring/Re-architecting during cloud migration often involves:
- Code modifications and restructuring
- Migrating without any alterations
- No changes to the code, just a change in the environment
- Rewriting the entire codebase
Refactoring/re-architecting typically involves making code modifications and restructuring to align the application with cloud requirements, improving its performance and scalability.
The ability of a single hypervisor to manage multiple virtual machines simultaneously is due to:
- Cloud-based architecture
- Network segmentation
- Resource virtualization
- VM cloning and snapshot capabilities
Resource virtualization is the fundamental capability that enables a hypervisor to manage multiple virtual machines concurrently. It abstracts and allocates physical resources efficiently.
Which virtualization method involves creating virtual versions of network resources, such as virtual switches or routers?
- Network Virtualization
- Desktop Virtualization
- Server Virtualization
- Containerization
The correct option is 'Network Virtualization.' Network virtualization involves creating virtual versions of network resources, such as switches, routers, and firewalls. These virtual network components can be managed and configured independently, allowing for flexible and isolated networking in a virtualized environment. Desktop virtualization is about virtualizing desktop environments, server virtualization focuses on virtualizing server hardware, and containerization deals with application-level virtualization.
Organizations that want to maintain sensitive data on their on-premises infrastructure while utilizing public cloud for non-sensitive operations often opt for a ________ model.
- Hybrid Cloud
- Multi-Cloud
- Private Cloud
- Public Cloud
In a Hybrid Cloud model, organizations can balance their need for security (private) with the flexibility of the public cloud. Sensitive data remains on-premises, while less sensitive operations can utilize the public cloud.
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.
When discussing cloud security, the process of ensuring that only authorized entities can access specific resources is known as:
- Access Control
- Authentication
- Authorization
- Secure Data Transfer
Access Control in cloud security ensures that only authorized entities have access to resources, thereby enhancing security.
In the context of GDPR, a ________ is the entity that determines the purposes, conditions, and means of the processing of personal data.
- Data Controller
- Data Inspector
- Data Processor
- Data Subject
In the context of GDPR (General Data Protection Regulation), a Data Controller is the entity responsible for determining how and why personal data is processed. They have control over the purposes, conditions, and means of processing.
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.

- Data Warehousing
- Graph Databases
- NoSQL Databases
- Real-time Data Processing
AWS Redshift is designed for data warehousing, making it optimized for SQL-based analytics, allowing complex querying and reporting.
