An organization is looking to consolidate their server infrastructure to optimize resource usage and reduce costs. By implementing which type of virtualization can they achieve this?
- Application Virtualization
- Network Virtualization
- Server Virtualization
- Storage Virtualization
Server virtualization is the ideal choice for consolidating server resources, enabling multiple VMs on a single physical server, optimizing resource usage, and reducing costs.
In the context of SaaS, the ability to serve multiple customers using a single instance of a software application is referred to as ________.
- Interoperability
- Multi-Tenancy
- Scalability
- Virtualization
Multi-Tenancy is a key characteristic of SaaS where a single instance of the software serves multiple customers, each with their data and configurations.
Cloud users are advised to regularly change their ________ to prevent account hijacking.
- Credit Card Information
- Email Addresses
- Passwords
- Physical Addresses
Cloud users are advised to regularly change their "Passwords" to prevent account hijacking. Frequent password changes make it more difficult for unauthorized users to access accounts.
In distributed systems, middleware plays a crucial role in:
- Communication and Integration
- Data Presentation
- End-User Interaction
- Processing and Storage
Middleware serves as an intermediary layer facilitating communication and integration between various distributed system components. It ensures data can flow between them efficiently.
A company wants to ensure zero downtime deployments for their application. They are considering Kubernetes. Which feature of Kubernetes would facilitate this?
- Automatic load balancing
- Cloud resource management
- Containerization
- Self-healing capabilities
Kubernetes provides self-healing capabilities, enabling it to automatically replace or reschedule containers if they fail, ensuring minimal downtime during deployments.
AWS Lambda supports automatic scaling by adjusting the number of ________ it runs in parallel.
- Containers
- Functions
- Instances
- Threads
AWS Lambda is a serverless compute service. It scales by adjusting the number of functions it runs in parallel, not instances, threads, or containers.
In a hybrid cloud, the orchestration between different cloud services is enabled by:
- Edge Computing
- Hybrid Cloud Management Platform (CMP)
- Hypervisor
- Virtual Private Network (VPN)
Orchestration in a hybrid cloud is facilitated by Hybrid Cloud Management Platforms (CMP), which provide tools to manage and integrate services across multiple cloud environments.
An e-commerce platform experiences high traffic surges during sale events. They want to migrate to the cloud efficiently, with minimal downtime. Which strategy would be best for them?
- Cloud Bursting
- Horizontal Scaling
- Serverless Computing (FaaS)
- Vertical Scaling
Cloud bursting is the most suitable strategy for an e-commerce platform with traffic surges. It allows the platform to scale dynamically to the cloud to handle peak loads while minimizing the migration effort.
In the context of AI in the cloud, what does a pre-trained model refer to?
- A model that is trained on new data
- A model that is trained on public data
- A model that requires further training
- A model that was trained by a user
A pre-trained model refers to a machine learning model that has already been trained on a large dataset and is available for use without further training. Typically, these models are trained on publicly available data.
Which type of cloud is made available to the general public by cloud service providers?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A "Public Cloud" is a cloud infrastructure made available to the general public by service providers. It is shared by multiple organizations and is typically accessed over the internet. Public clouds offer scalability and cost-efficiency.
