Answer: A,B
Explanation:
You interview stakeholders and conduct workshops to gather requirements and build consensus. Gathering requirements is an iterative process, which might require multiple rounds of interviews. Asking the right questions is vital, and you must gather both functional and nonfunctional requirements. A good strategy for a successful project is to bring the correct people together and build consensus.

Answer: A
Explanation:
Hosts provisioned with vSphere Auto Deploy cache the image (stateless caching):
Set up and apply a host profile for stateless caching. You can cache the image on a local disk, a remote disk, or a USB drive. Continue provisioning this host with vSphere Auto Deploy. If the vSphere Auto Deploy server becomes unavailable, for example because hundreds of hosts attempt to access it simultaneously, the host boots from the cache. The host attempts to reach the vSphere Auto Deploy server after the boot operation to complete configuration.
Hosts provisioned with vSphere Auto Deploy become stateful hosts:
Set up and apply a host profile for stateful installs. When you provision a host with vSphere Auto Deploy, the image is installed on the local disk, a remote disk, or a USB drive. For subsequent boots, you boot from the disk. The host no longer uses vSphere Auto Deploy.

NEW QUESTION # 32
An architect is finalizing the design for a new vSphere platform based on the following information:
All Windows virtual machines will be hosted on a dedicated cluster for licensing purposes.
All Linux virtual machines will be hosted on a dedicated cluster for licensing purposes. All management virtual machines will be hosted on a dedicated cluster.
A total of ten physical sites will be used to host virtual machines.
In the event of one physical datacenter becoming unavailable, the manageability of the virtual infrastructure in the remaining data centers should not be impacted.
Access to configure the management virtual machines via vCenter Server must be controlled through the management Active Directory domain.
Access to configure the Windows and Linux virtual machines must be controlled through the resource Active Directory domain.
The management and resource Active Directory domains are part of separate Active Directory forests and do not have any trusts between them.
The design will use Active Directory with Integrated Windows Authentication.

- B. The use of vSAN ReadyNodes
- C. The existing network is 10 GbE capable
- D. The number of 10 GbE capable ports in the vSAN ReadyNode

NEW QUESTION # 34
An architect is designing a series of new vSphere environments for an organization. The environments will be deployed in their US-East and US-West region data centers. Each data center may have one or more dedicated vSphere environments. Only the vSphere environments within a data center will be configured with Enhanced Linked Mode. The Chief Technology Officer (CTO) has authorized the use of VMware vRealize Automation Cloud for automation. The build team creates standardized virtual machine images for various operating systems in Open Virtualization Format (OVF) and publishes the latest version on an as-needed basis to an internal HTTPS-accessible repository.
The architect must design a content library topology that meets the following requirements:
A localized content library must be available in each data center.
Each content library must be updated when an image is updated and released by the build team.
The cloud automation platform must be able to consume the latest approved content library images.
It must leverage the existing build team processes.
What should the architect recommend to meet the requirements?
- A. Work with the build team to automate a JSON-based manifest to the repository when changes occur in the repository.
Create a subscribed content library for each vSphere environment.
Configure the content library to download content automatically. - B. Work with the build team to automate a JSON-based manifest to the repository when changes occur in the repository.
Create a subscribed content library for each vSphere environment.
Configure the content library to download content when needed. - C. Create a local content library for the primary vSphere environment in each data center.
Create a subscribed content library for each additional vSphere environment in each data center.
Configure the content library to download content automatically. - D. Work with the build team to create a local content library for each vSphere environment.
Import the OVF images when new image are published to the repository.
Answer: A
Explanation:
Build team publish to internal repository only... This need to be synchronized to other site. Therefore, suggest creating subscribed content library for each environment. After the synchronization finishes, the item content and metadata are downloaded to the storage of the subscribed library. On the Templates tab for the subscribed library, the value for the item in the Stored Content Locally column changes to Yes.

NEW QUESTION # 39
An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.
The platform has recently commissioned new hosts to update the development cluster.
The development cluster host configuration is:

512 GB RAM divided evenly between sockets
There is no resource contention
The benchmarking cluster host configuration is:
8 ESXi hosts with 2 sockets × 8 cores
256 GB RAM divided evenly between sockets
There is no resource contention
The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.
What is a possible reason for the difference in performance test results between the development and benchmarking clusters?
- A. The database tier breaches a single NUMA node boundary for the benchmarking cluster
- B. The development cluster can support a lower %Ready time per vCPU
- C. The database tier breaches a single NUMA node boundary for the development cluster
- D. The development cluster has more available RAM per host
