A cloud infrastructure that serves a specific community with common concerns (e.g., mission, security requirements, and compliance considerations) is known as:
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A Community Cloud is designed to serve a specific community with shared concerns like mission, security, and compliance requirements.
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.
Insider threats are particularly challenging to defend against because:
- Insiders are less likely to cause harm
- Insiders are less motivated to attack
- Insiders can be easily detected
- Insiders have better knowledge of the system
Insider threats are challenging to defend against because insiders have intimate knowledge of the system, making it harder to detect and prevent their activities. They may know weaknesses that external hackers wouldn't.
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.
Cloud monitoring tools often provide ________ capabilities, which allow for the setting of specific conditions that, when met, trigger notifications or actions.
- Alerting
- Debugging
- Indexing
- Profiling
Cloud monitoring tools offer alerting capabilities. These allow administrators to set specific conditions, like high CPU usage or downtime, triggering notifications or actions for proactive management.
If a sales team is struggling with tracking leads, sales opportunities, and customer feedback, which system would be most beneficial to implement?
- Customer Relationship Management (CRM)
- Enterprise Resource Planning (ERP)
- Human Resource Management System (HRMS)
- Sales Force Automation (SFA)
A Customer Relationship Management (CRM) system is specialized for managing customer interactions, leads, and sales opportunities, making it the most beneficial choice for the sales team's needs.
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.
