What is the most common cause of data breaches in organizations?
- Hardware Failure
- Human Error
- Natural Disasters
- Software Bugs
'Human Error' is the most common cause of data breaches, such as accidentally sharing sensitive information or falling for phishing attacks.
An organization is concerned about the performance overhead introduced by virtualization layers. They are considering a method where the guest OS is aware of the virtualization and can make direct calls to the physical hardware. Which virtualization technique addresses this?
- Emulation
- Full Virtualization
- Hardware-assisted Virtualization
- Paravirtualization
Paravirtualization is the technique where the guest OS is aware of virtualization and can make direct calls to the physical hardware. This minimizes the performance overhead introduced by virtualization layers.
A tech company has a monolithic application that suffers from long deployment times and scalability issues. They want to transition to a more modular and scalable architecture. What architectural style would you recommend?
- Event-Driven
- Microservices
- Monolithic
- Service-Oriented
The recommendation is to transition to Microservices, which breaks down the monolith into smaller, more manageable, and scalable components.
Which of the following is a potential security concern when using hypervisors for virtualization?
- Memory allocation issues
- Network latency
- Overcommitting resources
- VM escape attacks
VM escape attacks are a significant security concern where a malicious VM tries to break out of its virtual environment and access the host system, potentially compromising security.
What is the primary purpose of a cloud-based data lake?
- Managing cloud resources
- Running virtual machines
- Storing structured data
- Storing unstructured data
A cloud-based data lake is primarily used for storing unstructured data like raw text, images, audio, or log files, enabling flexible and scalable data storage for later processing and analysis.
The ________ migration strategy is also known as the "rehosting" approach.
- Re-architecting
- Re-engineering
- Re-hosting
- Re-platforming
The "rehosting" strategy, often referred to as the "lift-and-shift" approach, involves moving applications to the cloud without major modifications.
Middleware that provides a set of services to authenticate, authorize, and account users is known as ________.
- Communication Middleware
- Identity Middleware
- Security Middleware
- Transaction Middleware
Identity Middleware is responsible for authenticating users, authorizing their access, and accounting for their activities. It ensures secure user management.
Which of the following is a primary benefit of using SaaS?
- Complex software development
- Cost-effectiveness and scalability.
- High hardware maintenance cost
- Latency in accessing software.
A primary benefit of SaaS is cost-effectiveness and scalability. Users avoid high upfront costs and can easily scale their usage as needed.
Account hijacking can lead to which of the following unauthorized actions?
- Enhanced User Experience
- Improved Application Performance
- Increased Cloud Storage
- Unauthorized Data Access
Account hijacking can lead to unauthorized access to data, which can result in data breaches and loss of sensitive information.
Virtualization that requires modifications to the guest operating system to communicate with the underlying hardware is known as ________.
- Full Virtualization
- Hardware Virtualization
- Paravirtualization
- Software Virtualization
Paravirtualization is a form of virtualization that requires modifications to the guest OS to improve performance and communication with the underlying hardware. It offers enhanced efficiency but requires OS modifications.
