Hypervisor

You were recently hired by a small start-up company. The company is in a small office and has several remote employees. You have been asked to find 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 should you use? DaaS PaaS IaaS SaaS

IaaS

You want to be able to monitor and filter VM-to-VM traffic within a virtual network. What should you do? Route VM-to-VM traffic through a physical firewall and back to the virtual network. Define VLAN memberships on each VM. Create a virtual router with VRF technology. Implement a virtual firewall within the hypervisor.

Implement a virtual firewall within the hypervisor.

What key advantage does a virtual router have over a physical router? Routing protocols are not needed to route data between networks. Faster routing performance. Multiple networks can be connected to a single interface. Allows the Virtual Router Redundancy Protocol (VRRP) to be used.

Multiple networks can be connected to a single interface.

Which of the following best describes the Platform as a Service (PaaS) cloud computing service model? PaaS delivers everything a developer needs to build an application onto the cloud infrastructure. PaaS delivers software applications to the client either over the internet or on a local area network. PaaS delivers infrastructure to the client, such as processing, storage, networks, and virtualized environments. PaaS stores and provides data from a centralized location without the need for local collection and storage.

PaaS delivers everything a developer needs to build an application onto the cloud infrastructure.

A technician is unable to install virtualization software on a host computer. The host has more free disk space than required. Which of the following is MOST likely to be the cause? The motherboard UEFI/BIOS doesn't support hardware assisted virtualization. There is insufficient physical memory on the host to support both the host and the VM. The CPU doesn't have multiple core processors. There is no auxiliary hard drive to store the VM files.

The motherboard UEFI/BIOS doesn't support hardware assisted virtualization.

Match the virtualization implementations on the left with the appropriate characteristic on the right. Each type of implementation may be used once, more than once, or not at all. Drag Partial virtualization Full virtualization Paravirtualization Drop The virtual machine completely simulates a physical computer system. Operating systems do not need modification to run within virtual machines. Only some of the components of a virtual machine are virtualized. Guest operating systems directly access hardware resources in the hypervisor host system.
