Question 64

An organization's existing vSphere environments are configured for Enhanced Linked Mode. The DevOps team automates the creation of hardened virtual machine images for various operating systems. Their continuous integration/continuous delivery (CI/CD) pipeline runs a task at the end of a successful build, which uploads the Open Virtualization Format (OV) image to a sandbox content library, deploys a virtual machine from the image, and then destroys these objects after quality checks are complete.

The following requirements have been noted:

✑ All content libraries and images must be centrally created and managed.

✑ All images must be capable of being updated.

✑ All images must be refreshed and available to subscribed libraries within 24 hours.

✑ All images must provide details of the image contents and versions.

✑ All images must be capable of being reverted to a previous version.

✑ All images must be capable of having the hardware and guest operating system customized during deployment.

Which three recommendations should the architect make to design a content library solution that will meet these requirements? (Choose three.)

    Correct Answer: A, D, F

    To design a content library solution that meets the stated requirements, the following recommendations should be made: First, create a local content library in the primary vSphere environment and enable publishing to centrally manage and distribute images. Second, deploy the OVF images to vSphere and clone them as VM templates to a local content library since VM templates allow for updates, versioning, and customizations that are not possible with OVF templates. Finally, add a new subscriber library from each vSphere environment to ensure all environments have synchronized access to the updated images within 24 hours.

Discussion
c11Options: ABD

ABD A: Local library needed for centralized management. B: A 'subcription' ensure that content and replication can be managed from the soure i.e. Local library with publishing enabled. ( When you create a subscription for a local library, the result is a subscribed library. A publisher library is aware of its subscriptions. Subscriptions enable the administrator of the publisher library to control the content distribution. With subscriptions, content is distributed either when the subscriber initiates synchronization, or when the administrator of the local library publishes the library items to one or more of the existing subscriptions.)

DSITTAOptions: ADF

i suppose A,D,F. Not E because default auto sync time is 240 minutes so within 24 hours. No OVF to OVF as you cannot edit OVF, nly VM template.

nemisis95Options: ACF

sorry, it should be A,C,F A. Create a local content library in the primary vSphere environment and enable publishing. C . Deploy the OVF images to vSphere and clone as an OVF template to a local content library. F. Add a new subscriber library from each vSphere environment.

Led1973

Should be A,D,F as only VM templates can be edited and keep different versions

nemisis95

Good pickup. You are right, we can't check in/out OVF templates. "All images must provide details of the image contents and versions." "All images must be capable of being reverted to a previous version."

Also note that during the deployment of an OVF template, only guest OS customization is supported. Hardware customization is not supported.

ABD - "All content libraries and images must be centrally **created** and managed."

FR_WolfmanOptions: ADF

We create a new local content library, and we publish it in the primary vSphere environment. Then, for each other vSphere environment, we create a subscribed library synced with the primary one. To ensure versioning and reverts, the libraries must contain VM templates, as OVF are not supported for versioning. B : this one has no sense. A published library is…published…and that’s all. We don’t need to publish something again and again for each subscribed library C : OVF templates are not supported for versioning in content libraries E : By default, it is set at 240 minutes (4 hours), which is sufficient to ensure is refreshed within the required 24 hours. There is nothing to modify here.

HIC3540Options: ADF

ADF You can only 'publish' and 'sync'. There is not a publish option for subscribed libraries.

Correct answer ADF

IronMtnOptions: ABD

The difference between "ABD" and "ADF" is whether or not you create and publish a new subscription to a subscriber library. Since we have to use VM templates due to version control and other requirements of the question, then the way to replicate VM templates to subscribers is to use publishing. VMware is a bit confusing on this topic, but here is the documentation that clearly says you have to publish the library to subscribers in order to replicate VM templates: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vm_admin.doc/GUID-6345F652-4D9C-44AF-9D4C-5495CEB9999D.html (this is different than creating a subscription for a published local library) In addition, if you publish to a new subscriber then the content is automatically replicated. If you publish to an existing subscriber then you have to trigger it. See also https://williamlam.com/2023/05/benefits-of-vm-templates-vmtx-in-vsphere-content-library.html

redtopOptions: ADF

B is wrong because you do not have to Create and publish a NEW subscription to a NEW subscriber library for EACH target vSphere environment. There is no need to publish a NEW one for EVERY subscriber.

AlchotOptions: ADF

A: Create the library in the central location with publishing enabled D: Add the VM templates to library to support requested VM lifecycle F: Create and Subscribe other libraries to central library.

diegof1Options: ADF

A,D,F A. Create a local content library in the primary vSphere environment and enable publishing. D. Deploy the OVF images to vSphere and clone as a VM template to a local content library. F. Add a new subscriber library from each vSphere environment.
