What is the primary purpose of IT auditing in a cloud environment?
- Data Encryption
- Ensuring Compliance
- Network Troubleshooting
- Software Development
The primary purpose of IT auditing in a cloud environment is to ensure compliance with regulations and standards, assess the security of cloud infrastructure, and verify the proper management of data.
You are tasked with setting up a system where multiple microservices need to be orchestrated, scaled, and managed efficiently. Which technology would be most appropriate for this task?
- Apache Kafka
- Kubernetes
- MongoDB
- Redis
Kubernetes is a powerful orchestration system for microservices. It enables efficient scaling, management, and orchestration of containerized applications.
Key management in cloud encryption is crucial because:
- It enables data replication
- It ensures data availability
- It ensures data confidentiality
- It speeds up data transmission
Key management in cloud encryption primarily focuses on ensuring data confidentiality by securely managing encryption keys, preventing unauthorized access.
What is the default maximum execution time for a single AWS Lambda function invocation?
- 15 seconds
- 1 minute
- 5 minutes
- 15 minutes
The default maximum execution time for a single AWS Lambda function invocation is 3 seconds, not mentioned among the given options. Lambda allows you to set a maximum execution time, but the default is important to understand.
Which of the following refers to an incident where unauthorized individuals gain access to confidential data?
- Data Backup
- Data Breach
- Data Compression
- Data Encryption
A 'Data Breach' is an incident in which unauthorized individuals gain access to confidential data, often with malicious intent. It's a critical security concern.
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.
