- Elasticity
- Redundancy
- Scalability
- Self-Service On-Demand
Self-Service On-Demand is a fundamental cloud characteristic that allows developers to provision resources as needed, removing the need for infrastructure management.
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 virtualization, the physical machine on which the hypervisor runs is commonly referred to as the ________.
- Client
- Host
- Node
- Server
The physical machine that hosts the hypervisor and virtual machines is referred to as the Host. This is where the virtualization environment is created and managed.
A data breach that occurs due to an employee's unintentional actions, like clicking on a phishing link, is often referred to as a ________ breach.
- Accidental
- Cybersecurity
- Insider
- Malicious
An "Accidental" breach typically involves inadvertent actions by authorized users, making them susceptible to threats like phishing.
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.
