Which of the following is a MAJOR bene fi t you can expect from virtualization? Faster access to network resources. Reduction in the time it takes to resolve networking issues. More e ﬃ cient use of memory. Pooling of multiple operating systems on the same physical hardware. Explanation The major bene fi t you can expect from virtualizing your Linux servers is to be able to pool multiple operating systems on the same physical hardware. Faster access to network resources, more e ﬃ cient use of memory and reduction in resolving network issues are generally not listed as bene fi ts of using virtualization.

Block Container Blob Libraries Explanation Blob is short for binary large object. Blobs can be any type of data, like documents, video, audio, or backup data. You don't store and retrieve blob data the same way you would on a network drive. Instead, blob storage is managed from a dashboard or webpage. As you upload fi les, each fi le or blob is given a URL that's used to access or download the blob. This is especially useful because that URL can be used as a link in other websites. Block storage is like traditional drive space. Container and libraries are not cloud storage types.

Block Paravirtualization Blob Full virtualization Explanation Cloud providers o ff er two types of cloud storage, block storage and blob storage. Block storage is like traditional drive space. It might be o ff ered like a network drive or as a drive that's accessed by a cloud computing resource. Block storage stores fi les in directories in the same fashion as any other local fi le system. Full virtualization presents a virtual hardware environment, which emulates a physical hardware environment. Paravirtualization improves performance by allowing the guest operating system to communicate directly with some of the host's physical hardware. Blob is short for binary large object. Blobs can be any type of data, like documents, video, audio, or backup data. You don't store and retrieve blob data the same way you would on a network drive. Instead, blob storage is managed from a dashboard or webpage. As you upload fi les, each fi le or blob is given a URL that's used to access or download the blob.

Which of the following are the bene fi ts of using a container for running applications? Ports to other operating system and hypervisors. Operating system and applications are added to one system. Is larger than a virtual machine. Provides a quick startup time. Uses fewer hardware and software resources. Explanation The following are the bene fi ts of using a container for running applications: Uses fewer hardware and software resources. Provides a quick startup time. In addition, a container is smaller than a virtual machine. However, virtual machines provide the following bene fi ts: Operating system and applications are added to one system. Ports to other operating system and hypervisors. References  4.1.2 Linux Boot Process Facts  13.1.4 Linux Cloud and Virtualization Facts q_virt_containers_advantage_lp6.question.fex

However, the application is still a valuable tool to many company employees. Which of the following is the BEST solution to provide employees with a working copy of the application? Make the application available from the cloud by subscribing to a SaaS service. Create and distribute a container with the applications to employees. Make the application available from the cloud by subscribing to a PaaS service. Create and distribute a virtual machine with the application to employees. Explanation The best solution to providing employees with a working copy of the older application is to create and distribute a container with the app. It would consume less resources than a virtual machine. Subscribing to a PaaS or SaaS cloud service would be very expensive for simply running a single application.

The company is in a small o ﬃ ce and has several remote employees. You have been asked to fi nd a business service that would accommodate the current size of the company but would also be able to scale as the company grows. The service needs to provide adequate storage as well as additional computing power. Which cloud service model would work BEST for your company? SaaS PaaS IaaS DaaS Explanation In this scenario, the IaaS cloud model would work best for your company. Infrastructure as a Service (IaaS) delivers infrastructure to the client, such as processing, storage, networks, and virtualized environments. The client deploys and runs software without purchasing servers, data center space, or network equipment. Software as a Service (SaaS) delivers software applications to the client either over the internet or on a local area network. Platform as a Service (PaaS) delivers everything a developer needs to build an application onto the cloud infrastructure. The deployment comes without the cost and complexity of buying and managing the underlying hardware and software layers. Data as a Service (DaaS) stores and provides data from a centralized location without requiring local collection and storage.

You are familiar with running a variety of applications but not experienced in developing apps. Which cloud service model would work BEST for your home business? SaaS IaaS DaaS PaaS Explanation In this scenario, Software as a Service (SaaS) cloud model would work best for your home business. SaaS is designed for the average end user. SaaS provides applications that end users need to do their day-to-day work. Instead of installing the applications locally on their hard drive, users can run applications from the cloud, usually within a web browser. Infrastructure as a Service (IaaS) delivers infrastructure to the client, such as processing, storage, networks, and virtualized environments. The client deploys and runs software without purchasing servers, data center space, or network equipment. However, it provides more than you would need for your home o ﬃ ce. Platform as a Service (PaaS) delivers everything a developer needs to build an application onto the cloud infrastructure. The deployment comes without the cost and complexity of buying and managing the underlying hardware and software layers. Data as a Service (DaaS) stores and provides data from a centralized location without requiring local collection and storage. References 

Which of the following accurately describes those two types? (Select two.) A type 1 hypervisor runs on bare metal hardware and is referred to as a native hypervisor. A type 1 hypervisor is a software application that runs on top of a conventional operating system. A type 2 hypervisor runs on an operating system. A type 2 hypervisor is an operating system that runs the hypervisor as a dedicated system. A type 1 hypervisor runs on an operating system and bare metal hardware. Explanation A Type 1 hypervisor runs on bare metal hardware and is referred to as a native hypervisor. Microsoft Hyper-V and VMware ESX are examples of a Type 1 hypervisor. A Type 2 hypervisor runs on an operating system such as Windows, macOS, or Linux. VMware Workstation, Oracle VM VirtualBox, Parallels Desktop for Mac, and open-source QEMU are examples of Type 2 hypervisors.

Match the virtualization type on the left with the description on the right. Virtualization types may be used more than once. The virtual machine completely simulates a physical computer system. Full virtualization Operating systems do not need modi fi cation to run within virtual machines. Full virtualization Only some of the components of a virtual machine are virtualized. Partial virtualization Handles some of the virtualization processing the hypervisor would normally perform. Hardware-Assisted Virtualization Keyboard Instructions Explanation Full virtualization presents a virtual hardware environment, which emulates a physical hardware environment, provides the best isolation and security for VMs, and requires extra time and processing power to provide virtual hardware emulation. Paravirtualization improves performance by allowing the guest operating system to communicate directly with some of the host's physical hardware and is implemented by modifying the guest operating system with special device drivers. Hardware-assisted virtualization greatly improves a full virtualization environment and handles some of the virtualization processing the hypervisor would normally perform.
