Your customer has an application solution that runs 4 virtual machines. They need to replicate this solution repeatedly over a period of time into a number of separate production instances. What deployment method would you recommend to your customer as being the most suitable for their needs? Choose one.

 

A:

Power off the virtual machines and convert them to 4 templates. These 4 templates should be used to deploy 4 new virtual machines when required.When a new instance of the solution is required the 4 new virtual machines should be cloned from the original application solution virtual machines.Convert the 4 virtual machines to a single template. When a new instance of the application solution is required deploy the virtual machines using this template.Make multiple clones of the running virtual machines and copy them to secondary storage until they are required. Migrate the clones to production as required.

In order to ensure that you can successfully replicate between one environment and another you must verify that your customer’s virtual infrastructure respects certain limits before you start replication. Which of the following apply? Choose two.

You are discussing the use of virtual machine templates for deployment with a customer. The customer is unsure of the differences between the templates and clones and does not understand why they should create templates at all. Which of the following examples would you use to demonstrate the difference between them? Choose two.  A:

Templates can’t be edited or powered on and so are ideally suited for consistently deploying large numbers of identically configured virtual machinesClones are exact copies of virtual machines at the time of cloning and so are best suited for quickly creating test and development copies of virtual machines.Clones include all snapshots that are active on a virtual machine so you must use clones if you want to make a copy of virtual machine snapshotsTemplates are extremely portable and can be used to export and transport fully configured virtual machines outside of your vSphere environment

Your customer is investigating DR solutions for their vSphere production environment where they use DRS, HA and vMotion extensively. They have found that the cost estimates for storage solutions that can support hardware replication from their existing site is prohibitive. You are considering a proposing vSphere Replication as a solution for them but you must ensure that their environment can support it. Which of the following items must you check in order to be confident that vSphere Replication will be suitable? Choose two.  A:

Confirm that they do not use Storage vMotionConfirm that they are using iSCSI storage onlyConfirm that they have Enterprise Plus licensesConfirm that a 15 minute RPO meets their needs

You have proposed a solution for a customer to extend an existing vSphere cluster that supports HA and DRS where all virtual machines run Windows 2008. The existing cluster uses Intel Xeon X5650 CPUs, and you have specified the same CPUs for the new hosts in your proposal. The customer has challenged your design, indicating that they believe there are more cost effective hosts available that use AMD CPUs. What major impact would choosing the AMD based hosts have? Choose one.

 A:

vMotion, and fully automated DRS, would no longer work between all hostsHA could not be used as VMs might crash if restarted on the new hostsDRS could only continue to be used if it is reconfigured to use Cold MigrationThe customer would have to create an EVC DRS cluster to support both host types
