Data storage In a typical desktop virtualization solution, low-spec thin client computers replace desktop computers. The server handles even the data storage. Application processing Virtual desktop infrastructure (VDI) refers to using virtual machines to provision corporate desktops. The server performs all application processing in the virtual desktop environment (VDE).

What would be a reason an organization would require a private cloud service? (Select all that apply.) A cloud architecture is maintained and managed within an enterprise data center. Organizations can exercise greater control over the privacy and security of their services. A cloud service where several organizations share the costs and pool resources for a common concern. Make a blend of public and private cloud services with orchestration between them for employees and management.

A cloud architecture is maintained and managed within an enterprise data center. Organizations can exercise greater control over the privacy and security of their services. A private cloud is an entirely private cloud infrastructure owned by the organization that requires strict access control in its operations. Private cloud service allows the organization to exercise greater control over their services' privacy and security, keeping sensitive or regulated infrastructure, applications, and data on-premises.

Users at an organization would like to have access to their work data when not connected to the internet. What type of service should IT configure for the users? Metered utilization High availability File synchronization Shared resources

File synchronization File synchronization allows users to have a mirrored copy of their data on any number of devices. Data synchronization can occur across the cloud for files, email, contacts, and more.

Cloud service providers should ensure that they meet the criteria for reliable and responsive cloud delivery characteristics, such as metered utilization, rapid elasticity, and high availability. What other criteria should cloud service providers meet? File synchronization File sharing Resource sharing Data storage

File synchronization One of the advantages of cloud storage is automated file synchronization between different devices, such as a PC and smartphone.

Rapid elasticity refers to the cloud computing system's ability to do what? Achieve pooling of shared resources. Handle changes to demand in real time. Provide per-use billing for resources consumed by the cloud. The service experiences very little downtime.

Handle changes to demand in real time. Rapid elasticity refers to the system's ability to handle changes to demand in real-time. A system with high elasticity will not experience loss of service or performance if demand suddenly doubles or more.

High availability High availability (HA) means that the service experiences very little downtime. For example, a service with "Five Nines" or 99.999% availability experiences only 5 minutes and 15 seconds annual downtime.

With cloud computing, organizations can expand resources as needed. Services expand rapidly with virtualization through metered utilization using a paid cloud service provider, allowing access to increased resources. What are some of the other benefits the cloud provides? (Select all that apply.) High availability Scalability Elasticity Data control

High availability High availability (HA) is a requirement for short periods of downtime, typically due to planned maintenance and unscheduled outages. Scalability Scalability is the cost of supplying the cloud services based on the number of users receiving the service. The benefit for an organization is it can scale up or down services based on the need. Elasticity Rapid elasticity is the cloud service provider's ability to handle changes to demand in real-time. Systems with high elasticity will be less affected in changes to service or performance when scaling up services.

A company deploys a new cloud service for its customers and its salespeople. Depending on the login access, users of the service will either shift to a resource center internal to the organization or to a forum where customers can freely collaborate. What cloud model does the company deploy? Public cloud Private cloud Hybrid cloud Community cloud

Hybrid cloud A hybrid cloud type is a cloud computing solution that implements some sort of hybrid public/private/community.

An engineer at an organization quickly deploys a small network in a cloud space. The network includes a subnet and router hidden behind a firewall for software testing. What type of service includes the ability to roll out such a cloud-based network? PaaS IaaS SaaS DaaS

IaaS Infrastructure as a service (IaaS) is a means of provisioning IT resources, such as servers, load balancers, and storage area network (SAN) components, quickly.

The company administrator wants to provision IT resources, such as servers, load balancers, and storage area network (SAN) components, to deploy when they need them rather than purchase these components separately. Which service model would be best? IaaS SaaS PaaS DaaS

IaaS Infrastructure as a service (IaaS) is a means of provisioning IT resources, such as servers, load balancers, and storage area network (SAN) components, quickly.

An IT administrator at a large company receives an alert that disk usage for a cloud-based service is over an established data transfer quota. Which service does the company utilize that triggers such an alert? Shared resources Metered utilization Rapid elasticity High availability

Metered utilization The end-user is interested in and pays for only the services provided by the cloud. The per-use billing for resources consumed by the cloud is metered utilization.

A cloud service provides a billing dashboard that reports a virtual machine's uptime, disk usage, and network bandwidth consumption. What characteristic does this demonstrate? Shared resources Elasticity Metered utilization Scalability

Metered utilization The per-use billing for resources consumed by the cloud is known as metered utilization. The metering measurement is from resources such as storage, processing, bandwidth, or active users.
