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.
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.
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.
With Hypervisor virtualization, multiple independent domains or instances can run on a single physical system, sharing the same hardware resources.
- Application
- Cluster
- Container
- Network
Hypervisor virtualization, also known as hardware virtualization, involves a hypervisor that allows multiple VMs to run independently on the same physical hardware.
A network administrator wants to simulate a complex network topology without buying additional hardware components. Which virtualization approach should they consider?
- Network Emulation
- Network Virtualization
- Server Virtualization
- Storage Virtualization
Network emulation allows the simulation of complex network topologies using software, eliminating the need to buy additional hardware, making it an efficient choice for the network administrator.
Cloud computing is primarily about:
- Delivering computing services over the internet
- Managing office supplies
- Running video game tournaments
- Writing computer code
Cloud computing is primarily focused on delivering computing services, such as servers, databases, and applications, over the internet, rather than managing supplies, gaming, or coding.
Which of the following is NOT a characteristic of cloud computing?
- Broad Network Access
- High Latency
- On-Demand Scalability
- Self-Service Provisioning
High latency is NOT a characteristic of cloud computing. Cloud services aim for low latency, providing quick access to resources over the network.
In AI services, ________ is an approach where computation is done on-device, reducing the need to send data back and forth to the cloud.
- Cloud Computing
- Edge AI
- IoT AI
- Offloading
Edge AI involves performing AI computations on-device, reducing the need for data to be sent to the cloud. It enhances privacy, reduces latency, and saves on bandwidth in AI applications.
When considering long-term commitments to cloud providers, organizations can often negotiate ________ to optimize costs.
- Data Transfer Costs
- On-demand Pricing
- Reserved Instances
- Service-level Agreements (SLAs)
Organizations can negotiate "Reserved Instances" as part of long-term commitments to cloud providers. These provide cost savings compared to on-demand pricing, especially for stable workloads with predictable usage patterns.
________ ensures that cloud services are available over the network and accessed through standard mechanisms.
- Accessibility
- Availability
- Compatibility
- Integration
Availability is the aspect of cloud services that guarantees they are consistently accessible over a network using standard methods, promoting reliability and dependability.
What is a critical advantage of community clouds for organizations with strict regulatory requirements?
- Cost-Effectiveness
- Geographic Distribution
- Shared Regulatory Compliance Burden
- Unlimited Scalability
Community clouds allow organizations to share the regulatory compliance burden with similar entities, reducing the cost and complexity of meeting strict regulations.
How does multi-tenancy relate to SaaS?
- It Enhances Scalability
- It's About Multiple Data Centers
- It's Not Relevant
- It's a SaaS Model
Multi-tenancy is a core concept in SaaS. It refers to the ability of a single instance of a software application to serve multiple customers (tenants). It enhances scalability and resource utilization in SaaS environments.
