An architect is tasked with recommending a solution for a company that is running out of VLANs. Currently the company is running two separate data centers based on vSphere including an Enterprise Plus license. In the first data center, the problem was solved by using VMware NSX and overlay network. In the second data center, there is currently no VMware NSX implementation in place and no budget for additional licenses.

What should the architect recommend as a potential solution to provide support for additional VLANs?

• There is a dedicated ESXi cluster, supporting all management services.

There is a dedicated ESXi cluster for all line-of-business applications.

• Network traffic is serviced by NSX-T.

There is a dedicated ESXi cluster for virtual desktop infrastructure (VDI).

• Network traffic is serviced by NSX-T.

Which additional non-functional requirement should the architect include in the design to support the new service?

In a meeting to discuss the minimum viable product (MVP) deployment of a new customer-facing application, the key stakeholder shares details of the application components and the application administrators share details of performance and integrity tests for the application.

The application will be made up of the following components:

• A web server

-Steps to confirm the web server is operating correctly will take 15 minutes after the application server is online.

• An application server

-Steps to confirm application server integrity will take 15 minutes after the database is online.

• A database server

-The database server will be managed by a database administrator, with an agreed service-level agreement (SLA) to restore and validate database services within one hour.

The existing VMware infrastructure offers a recovery point objective (RPO) of 5 minutes and recovery time objective (RTO) of 15 minutes through a combination of backups and replication.

In the event of an outage impacting all three application components, how long will it take for the application to recover and complete all checks?

The Chief Information Security Officer (CISO) for an organization is concerned about the security posture of the operating system images that are used for the provisioning of their Software-as-a-Service (SaaS) applications. The organization is in a growth period. The organization is opening a new data center to launch its next phase of new SaaS-based solutions.

The DevOps team currently creates encrypted virtual machine (VM) templates that are used for various operating systems and adds these to the vSphere inventory. The DevOps team already uses a published content library and has been granted a role with the ability to add and delete library items.

The following requirements have been noted:

• Impacts to the DevOps team’s operational processes must be kept to a minimum.
• The DevOps team must be able to regularly check out a copy of the image for updates and check in a new version of the image.
• Images must be synchronized from the primary data center to the new data center.

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

An architect is designing a VMware solution for a customer to meet the following requirements:

• The solution must use investments in existing storage array that supports both block and file storage.
• The solution must support the ability to migrate workloads between hosts within a cluster.
• The solution must support resource management priorities.
• The solution must support the ability to connect virtual machines directly to LUNs.
• The solution should use existing 32G fabric infrastructure.
• There is no budget for additional physical hardware.

An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.

During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:

• The solution must initially support the concurrent running of 300 production and 600 development virtual machines.
• The production environment should be delivered across two geographically dispersed data centers. The development environment must be vSphere-based but does not have to be deployed on-premises.
• The two data centers are connected to each other through multiple diversely routed, high bandwidth and low latency links.
• The customer’s server hardware standard document states that all virtual infrastructure hosts must be based on blade architecture only.
• The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities, such as the monthly software patching and ad-hoc hardware break/fix.
• All virtual machine backups must be completed using the existing backup service. The recovery time objective (RTO) for the service is four hours.
• The recovery point objective (RPO) of the service is 24 hours.

Given the information from the customer, which two would be classified as assumptions within the design? (Choose two.)
