Answer : D

Answer : A

Answer : B

Blockchain and AI have a symbiotic relationship with the cloud. Blockchain provides the trusted, decentralized source of truth, AI powers the analytics and decisions made from the collected data, and cloud provides the globally distributed, scalable, and cost-efficient computing resources to support both technologies.

Answer : A

The Internet of Things, or IoT, refers to the billions of physical devices around the world that are now connected to the internet, all collecting and sharing data.

Answer : A

The NIST definition lists five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service

Answer : A

The IT equipment within a data center consists of three main elements necessary for a computing environment to function: Compute: The memory and processing power needed to run applications that are usually supplied by enterprise-grade servers. Storage: Data centers include primary and backup storage devices. They may be hard disk or even tape drives, but best-in-class facilities typically feature all-flash arrays. Networking: They contain a broad array of networking equipment, ranging from routers and switches to controllers and firewalls. In addition to the IT equipment it contains, every data center houses that equipment's support infrastructure, including the following: Environmental controls: Sensors monitor the airflow, humidity, and temperature in the facility at all times, with systems in place to guarantee that temperature and humidity remain within hardware manufacturers' specified ranges. Server racks: Most data center equipment is housed in specially designed racks or in purpose-built cabinets or shelving. Power supplies: Most data centers employ battery-based backup power systems able to compensate for short-term power outages and larger generators that can supply power in case longer commercial power grid outages occur. Cabling and cable management systems: An enterprise data center may contain hundreds of miles of fiber optic cable. Systems and equipment to keep that cabling orderly and accessible are a must.

Answer : A

Private cloud (also known as an internal cloud or corporate cloud) is a cloud computing environment in which all hardware and software resources are dedicated exclusively to, and accessible only by, a single customer. Private cloud combines many of the benefits of cloud computing---including elasticity, scalability, and ease of service delivery---with the access control, security, and resource customization of on-premises infrastructure. Advantages of private cloud include the following: Full control over hardware and software choices. Private cloud customers are free to purchase the hardware and software they prefer, vs. the hardware and software the cloud provider offers. Freedom to customize hardware and software in any way. Private cloud customers can customize servers in any way they want and can customize software as needed with add-ons or through custom development. Greater visibility into security and access control, because all workloads run behind the customers' own firewall. Fully enforced compliance with regulatory standards. Private cloud customers aren't forced to rely on the industry and regulatory compliance offered by the cloud service provider.
