In the context of virtualization, what is "paravirtualization"?
- A method to create virtual machines
- A technique to emulate hardware devices
- A technology to enhance graphics performance
- A virtualization technique where the guest OS is modified to be aware of the virtualization layer
Paravirtualization involves modifying the guest OS to work more efficiently with the hypervisor, improving performance and allowing for efficient communication with the host.
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.
One of the main benefits of using cloud services for AI and ML is the availability of large-scale ________ for training complex models.
- Data storage and processing
- E-commerce websites
- IoT devices
- Social media platforms
Cloud providers offer extensive data storage and processing capabilities, enabling users to access large datasets for training complex AI and ML models. This resource scalability is a significant benefit.
If you want to execute a piece of code in response to changes in Google Cloud Storage, you'd typically use ________.
- Google Cloud Dataflow
- Google Cloud Functions
- Google Cloud Pub/Sub
- Google Cloud Tasks
Google Cloud Pub/Sub is often used to trigger code execution in response to changes in Google Cloud Storage, making it a suitable choice.
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.
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.
Google Cloud Functions are stateless, meaning they do not ________ state between invocations.
- Preserve
- Reset
- Retain
- Share
Google Cloud Functions are stateless, which means they don't retain state between invocations. Each invocation starts with a clean slate.
