Question1: The Chief Operating Officer (COO) at an organization raises concerns that their virtual infrastructure environment is vulnerable. Recently, a security-related issue with a virtual machine caused all management services to become unavailable. No budget is available in the short term for additional platform investment. An architect is asked to review the current environment and make recommendations to mitigate concerns.
A virtualization administrator has provided the following details:
There is a single four node cluster of ESXi servers
There are two, Layer 2, physical network switches connecting resources
The data center network is presented as a single /16 subnet
Given the information provided, which functional requirement should the architect include in the design to mitigate the COOs concerns?

Question2: An architect is designing a new VMware software-defined data center (SDDC) that will consist of 100 branch sites connected to a single VMware vCenter Server within the primary data center. To allow for the use of existing automation scripts, there is a requirement to replicate the names of the virtual distributed port groups across all sites. The procurement team purchases licensing and there is no further budget allocated.
Which design decision should the architect make to meet this requirement?

Question3: 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?

Question4: An architect is designing a new VMware solution for a customer that has a number of different resource profiles.
The following are the business requirements for the design:
The solution must support virtual machines with the following storage profiles:
- Write-intensive
- Backup
- Write-Once-Read-Many (WORM) archive
The solution must support migration of virtual machine disks between storage profiles.
The WORM archive data must be located at an isolated secure site.
The backup storage array must only be connected to a backup media server.
All data should be recoverable from backup.
Which design decision should the architect make to meet the business requirements?

Question5: A customer has a database cluster with 40/60 read/write ratio and a high IOPs requirement with no contention on an all-flash vSAN cluster.
Which two storage settings should be configured for best performance? (Choose two.)

Question6: During a requirements gathering workshop, the customer's Chief Information Security Office (CISO) provides the following requirements that are pertinent to the design of a new vSphere environment:
All operating system critical patches must be installed within 24 hours of release.
All virtual machine templates must be updated every three months in line with company policy.
Which requirement classification is being gathered for the design documentation?

Question7: An architect is designing storage for a new vSphere environment to meet the following requirements:
Asynchronous replication is required between two sites.
The impact on the storage layer should not impact the performance of the compute layer.
Each application tier will require different replication attributes.
Virtual machine live migration across compute and storage must be supported.
Virtual machine aware back up will be leveraged.
Operational management overhead should be minimized.
Operational automation should be supported.
Which storage design recommendations would meet the requirements?

Question8: An architect is preparing a design for a company planning digital transformation. During the requirements gathering workshop, the following requirements (REQ) and constraints (CON) are identified:
REQ01 The platform must host different types of workloads including applications that must be compliant with internal security standard.
REQ02 The infrastructure must initially run 100 virtual machines.
REQ03 Ten of the virtual machines must be compliant with internal security standard.
REQ04 The internal security standard specifies logical network separation for in-scope applications.
CON01 The customer has already purchased the licenses as part of another project.
CON02 The customer has five physical servers that must be reused.
Additionally, based on resource requirements, four physical servers will be enough to run all workloads. Which recommendation should the architect make to meet requirements while minimizing project costs?

Question9: 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.
How should the architect document the vCenter Server configuration for this design?

Question10: An architect is designing a new vSphere environment with the following resources:
600 vCPU
5,760 GB RAM
Average resource usage is:
60 vCPU
1,152 GB RAM
The design must meet the following requirements:
The environment has the ability to burst by 25%.
Each host can schedule 36 vCPUs and has 512 GB RAM.
Management overhead is 20%.
What is the minimum number of hosts required to meet the design requirements?

Question11: Which two statements are true about gathering functional business and application requirements? (Choose two.)

Question12: 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:
4 ESXi hosts with 2 sockets × 16 cores
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?

Question13: An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.
Which design recommendation should the architect make for distributing the resource profiles?

Question14: An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.
Which ESXi deployment method should the architect use?

Question15: A customer is deploying a new cluster and wants to be able to patch and update two hosts in parallel. The cluster must be able to maintain N+1 resiliency across the remaining hosts while patching activities are performed. The current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.
What is the minimum number of hosts the customer will require in the cluster in order to meet the required resiliency level?

Question16: The storage team at an organization is planning to migrate from an older Fibre Channel storage environment to a new environment using IP-based storage.
Which two switch features or characteristics are appropriate for IP storage networks? (Choose two.)

Question17: Refer to the exhibit.

During a requirements gathering workshop, the customer shares the following about their existing ESXi host virtual networking infrastructure:
The customer confirms that:
Each ESXi host has approximately 200 virtual machines.
They want to maximize the number of concurrent virtual machine migrations.
When placing a host in maintenance mode, it takes a long time to evacuate the virtual machines.
Which two recommendations should the architect make in order to help the customer overcome their challenge? (Choose two.)

Question18: 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.)

Question19: 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?

Question20: An architect is reviewing a physical storage design. The customer has specified that storage DRS will be used for ease of operational management for capacity and performance.
Which recommendation should the architect include in the design?
