NEW QUESTION # 56
An architect is working on the cluster layout design for a new vSphere solution. The resource requirements for the first cluster state that memory demand can experience spikes of up to 20% over the documented average demand during peak business hours and the cluster must be able to handle these spikes without contention.
Which design quality is being referenced?
- A. Recoverability
- B. Manageability
- C. Availability
- D. Performance
Answer: D
Explanation:
Performance refers to the system's ability to meet the required service levels under various conditions, including handling spikes in memory demand. In this case, the architect is ensuring that the cluster can handle memory spikes of up to 20% without contention, which is a key performance requirement to ensure that the workloads run optimally during peak business hours.
The ability to accommodate these memory demands without impacting performance directly aligns with ensuring that the system performs as expected under peak load conditions.
NEW QUESTION # 57
An architect is designing the access management component of a vSphere-based solution. During a requirements gathering workshop, the customer states that the architecture must use a centralized user authentication solution.
The architect decides that an Open Lightweight Directory Access Protocol (OpenLDAP) solution would meet the requirement. The security team intervenes and requires that the solution use the corporate Active Directory Domain Services solution.
At which point did the architect's design become constrained?
- A. When the architect finished documenting all of the requirements.
- B. When the customer provided the requirement for the use a centralized user authentication solution.
- C. When the customer required the use of the corporate Active Directory Domain Services solution.
- D. When the architect made the design decision to use an OpenLDAP solution for user authentication.
Answer: C
Explanation:
The design became constrained when the customer required the use of the corporate Active Directory Domain Services (AD DS) solution. The security team's intervention and insistence on using the corporate Active Directory effectively limited the options available for the authentication solution, as OpenLDAP was no longer a valid choice. At this point, the solution's scope was restricted to ensure compatibility with the customer's existing Active Directory infrastructure, which imposed a specific requirement on the design.
NEW QUESTION # 58
Which VMware product offers a software-defined storage solution, providing distributed storage architecture that spans multiple vSphere clusters?
- A. vSphere Replication
- B. vSAN
- C. VMware Workstation
- D. NSX-T
Answer: B
NEW QUESTION # 59
An architect is designing a new vSphere solution. The solution will be used to host workloads that have multiple dependencies. The customer provides the following information regarding the workloads:
Workload 1: Self-Service Portal
Workload 2: Database
Workload 3: Identity Broker
Workload 4: Reporting Tool
Workload 5: Management Tool
Application A is formed of workloads 1 and 2 and has a dependency on workload 3 Application B is formed of workloads 2 and 4 and has a dependency on workload 3 Application C is formed of workload 5 and has a dependency on workload 4 How should the architect document the vSphere HA requirements to ensure that all of the applications can be recovered in the event of a host failure while observing the dependencies?
- A. Set vSphere HA to Shut Down and Restart VMs in response to a Host Isolation Set the Restart Priority of workload 3 to High Set the Restart Priority of workloads 4 and 5 to Medium Set the Restart Priority of workloads 1 and 2 to Low
- B. Set vSphere HA to Restart VMs in response to a Host Failure
Set the Restart Priority of workloads 3 and 4 to High
Set the Restart Priority of workload 5 to Medium
Set the Restart Priority of workloads 1 and 2 to Low - C. Set vSphere HA to Shut Down and Restart VMs in response to a Host Isolation Set the Restart Priority of workloads 3 and 4 to High Set the Restart Priority of workload 5 to Medium Set the Restart Priority of workloads 1 and 2 to Low
- D. Set vSphere HA to Restart VMs in response to a Host Failure
Set the Restart Priority of workload 3 to High
Set the Restart Priority of workload 4 to Medium
Set the Restart Priority of workloads 1, 2 and 5 to Low
Answer: B
Explanation:
The goal here is to ensure that, in the event of a host failure, the workloads are restarted in the correct order based on their dependencies:
Workload 3 (Identity Broker) is required by both Application A and Application B as a dependency. It needs to be set to High Restart Priority, ensuring that it is restarted before the other dependent workloads.
Workload 4 (Reporting Tool) is required by Application B and Application C, so it should be set to High Restart Priority to ensure it is available before the other dependent workloads (like Workload 5).
Workload 5 (Management Tool) is required by Application C and should have a Medium Restart Priority, meaning it will be restarted after Workload 4.
Workloads 1 and 2 (Self-Service Portal and Database) have Low Restart Priority because they are dependent on Workload 3 (and Workload 4), but they do not have further critical dependencies after Workload 3, so they should be restarted last in the event of a failure.
This setup ensures that all applications can be recovered properly in the event of a host failure, with each workload restarting in the correct order to maintain the application dependencies.
NEW QUESTION # 60
During a requirements gathering workshop, the customer provides the following requirement:
- A new vSphere platform must be designed securely and all interfaces
must be protected against potential snooping.
How should this non-functional security requirement be documented?
- A. Interfaces must be audited.
- B. Unauthorized access to interfaces must be reported within 15 minutes.
- C. Encrypted channels must be used for all communications.
- D. Communications must be through Private VLANs (PVLAN).
Answer: D
Explanation:
Your ESXi host uses several networks. Use appropriate security measures for each network, and isolate traffic for specific applications and functions. For example, ensure that VMware vSphere vMotion traffic does not travel over networks where virtual machines are located. Isolation prevents snooping. Having separate networks is also recommended for performance reasons.

NEW QUESTION # 69
As part of designing a greenfield vSphere-based hosting solution, an architect is responsible for defining a patch management solution for the virtual infrastructure.
During initial meetings with the customer, the following information is provided:
There are two geographically dispersed physical sites (primary and secondary) in scope for the solution.
The inter-site connectivity has been classified as low bandwidth and high latency.
The customer has the following requirements:
REQ001 - Only IT Security Team-approved versions of VMware Tools should be installed across all workloads within the infrastructure.
REQ002 - The solution should minimize traffic across the inter-site link.
REQ003 - Upgrades to the virtual infrastructure should continue in the event of a failure with either site.
A combination of which three design decisions could the architect make to ensure the requirements are met?
(Choose three.)
- A. The solution will ensure that all VMware ESXi hosts within a site have access to the local VMFS datastore containing the shared VMware Tools repository.
- B. The solution will set the UserVars.ProductLockerLocation advanced system setting on each VMware ESXi host to point to the local site shared Repository
- C. The solution will set the UserVars.ToolsRamdisk advanced system setting on each VMware ESXi host to "1" (enabled).
- D. The solution will use VMware Autodeploy to ensure the latest version of VMware Tools is deployed to each workload.
- E. The solution will create a shared repository on a VMFS datastore within each site that contains all approved versions of VMware Tools.
- F. The solution will create a shared repository on a VMFS datastore within the primary site that contains all approved versions of VMwareTools.
Answer: A,B,E
Explanation:
The solution will ensure that all VMware ESXi hosts within a site have access to the local VMFS datastore containing the shared VMware Tools repository.
This decision ensures that each site has local access to the VMware Tools repository, which minimizes traffic across the low-bandwidth, high-latency inter-site link. By keeping the repository within each site, the local ESXi hosts can access the repository without needing to traverse the inter-site link frequently.
The solution will set the UserVars.ProductLockerLocation advanced system setting on each VMware ESXi host to point to the local site shared repository.
This ensures that each ESXi host points to the local site repository for VMware Tools. This approach minimizes inter-site traffic by ensuring that all updates and patches are performed using local resources, avoiding the need to transfer VMware Tools files over the low-bandwidth, high-latency connection.
The solution will create a shared repository on a VMFS datastore within each site that contains all approved versions of VMware Tools.
This decision ensures that both sites have a local copy of the approved VMware Tools versions, in line with REQ001, which mandates that only IT Security Team-approved versions of VMware Tools should be installed. Additionally, it minimizes inter-site traffic, as both sites will use their local repositories.

NEW QUESTION # 73
An architect is designing a vSphere-based application hosting solution in a brownfield site.
The following information has been provided during the requirements gathering workshop:
The solution should support 5,000 compute workloads across two physical sites.
The CFO has approved budget for the purchase of new server and network hardware only.
The existing storage array is currently Fibre Channel connected with 2 x 8 Gbps interfaces to a dedicated Storage Area Network (SAN) fabric.
The existing storage array does not support integration with vSphere API for Storage Awareness.
The existing storage array can be configured to support NFS storage.
The existing vSphere administration team will responsible for operational management of the new solution.
Which storage technology should the architect recommend based on these requirements?
- A. VMware vSAN
- B. iSCSI
- C. Fibre Channel
- D. vSphere Virtual Volumes (vVols)
Answer: B
Explanation:
Based on the requirements provided, the architect should recommend iSCSI for the following reasons:
Existing Storage Array: The existing storage array does not support integration with vSphere API for Storage Awareness (VASA), which is required for vVols and VMware vSAN. This means that vVols and vSAN cannot be used without significant upgrades or changes to the storage infrastructure.
Existing Fibre Channel Connectivity: The storage array has Fibre Channel connectivity, but it is limited to 2 x
8 Gbps interfaces and is not compatible with advanced features required by modern solutions like vVols. In addition, Fibre Channel is traditionally complex to manage and requires specialized knowledge, which may not align with the existing vSphere administration team's expertise.
Support for NFS Storage: The storage array can be configured to support NFS storage, which is an efficient, simpler-to-manage option compared to traditional Fibre Channel or iSCSI. Since iSCSI is also IP-based, it aligns well with the existing vSphere environment.
Scalability and Simplicity: iSCSI allows for easy integration with vSphere and is a highly scalable option for expanding storage across two sites, which meets the requirement of 5,000 compute workloads across two physical sites. It is also easier to manage compared to Fibre Channel and vVols.
NEW QUESTION # 74
