A ________ is a software layer that abstracts the physical hardware to create multiple virtual machines.
- Compiler
- Debugger
- Hypervisor
- Kernel
A Hypervisor is a crucial software layer that manages virtual machines by abstracting and controlling access to physical hardware resources. It enables the creation of multiple VMs on a single physical server.
When an organization wants to optimize its application to be more scalable and resilient by redesigning it for the cloud, they are likely using the ________ strategy.
- Re-architecting
- Re-factoring
- Re-hosting
- Re-platforming
The "re-architecting" strategy involves redesigning applications to leverage cloud-native features, enhancing scalability and resilience.
Which characteristic of cloud computing allows resources to be provisioned without human interaction?
- High Availability
- Redundancy
- Self-Service Provisioning
- Virtualization
Self-service provisioning enables users to allocate cloud resources independently, reducing the need for manual intervention in resource allocation.
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.
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.
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.
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.
Which of the following is a primary benefit of virtualization?
- Cost Savings
- Faster Processing
- Improved Security
- Reduced Complexity
A primary benefit of virtualization is cost savings. It reduces hardware costs, energy consumption, and maintenance expenses by consolidating multiple VMs on a single physical machine.
