An architect is designing an environment for a retail customer. The design will use a single small vCenter Server Appliance and a cluster of eight ESXi hosts at a remote site. There is a single 10 GbE connected network at the remote site to support all management services. It is not possible to create additional management networks at the remote site. Virtual machine backups at the site will be dependent on the vCenter Server being available.
Which design decision should the architect make to maximize availability for backups?
- A . vCenter Server High Availability will be configured.
- B . The vCenter Server Appliance will be protected with vSphere Fault Tolerance.
- C . The cluster will be configured to use vSphere DRS in fully automated mode.
- D . The cluster will be configured with vSphere HA and set to restart virtual machines based on guest operating system heartbeat monitoring.
During a transformation project kick-off meeting, an architect highlights specific areas on which to focus while developing the new conceptual design.
Which two of the listed statements are business requirements? (Choose two.)
- A . The project should use the existing storage devices within the data center
- B . Sites must support a network latency of less than 12 ms round-trip time (RTT)
- C . The solution must allow data replication between sites
- D . There is no budget specifically assigned for disaster recovery
- E . There must not be a single point of failure for the virtual infrastructure
A new vSphere platform is being created. The platform will host virtual machines that will run management services and line-of-business applications.
What should the architect consider when designing the number and type of clusters required?
- A . Maximum tolerable downtime
- B . Predicted platform growth
- C . Auditing requirements for the virtual machines
- D . The level of isolation required between virtual machine classifications
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?
- A . The virtual infrastructure environment must connect application virtual machines and management services to new physical network switches
- B . The virtual infrastructure environment must connect application virtual machines and management services to separate distributed virtual switches (DVS)
- C . The virtual infrastructure environment must connect application virtual machines and management services to separate VLANs
- D . The virtual infrastructure environment must connect management services to a vSphere standard switch (VSS)
Following a recent acquisition, the architect learns that both companies use vSphere on-premise and will need to combine the data centers into one. The acquired company’s licenses will not be renewed for cost-savings related to the acquisition. All consumed vSphere licenses must have active support to support line-of-business operations. The merged environment must maintain 25% spare capacity. The architect has a small budget remaining unallocated for hardware.
The architect has calculated that the current vSphere environment can absorb the acquired company’s virtual machines but the cluster will run at 90% memory utilization and at 50% CPU utilization.
Which design decision can the architect make to incorporate the new company’s virtual machines into the combined vSphere environment?
- A . Migrate the acquired company’s virtual machines into the vSphere environment as it will currently fit.
- B . Use the current budget to add memory to the cluster to increase each ESXi host’s capacity and add the new virtual machines.
- C . Purchase extra hosts to add to the cluster in anticipation of adding the acquired company’s virtual machines.
- D . Purchase new licenses for some of the acquired company’s ESXi hosts and add them to the cluster to hold the acquired company’s virtual machines.
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?
- A . The database tier breaches a single NUMA node boundary for the benchmarking cluster
- B . The database tier breaches a single NUMA node boundary for the development cluster
- C . The development cluster can support a lower %Ready time per vCPU
- D . The development cluster has more available RAM per host
A customer has six hosts available in a cluster. When running at full capacity, all virtual machines can be run on two hosts.
How many hosts can the customer place into maintenance mode at the same time while still providing N+2 resiliency to the cluster?
- A . Two
- B . Three
- C . One
- D . None
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.)
- A . Create a local content library in the primary vSphere environment and enable publishing.
- B . Create and publish a new subscription to a new subscriber library for each target vSphere environment.
- C . Deploy the OVF images to vSphere and clone as an OVF template to a local content library.
- D . Deploy the OVF images to vSphere and clone as a VM template to a local content library.
- E . Edit the Auto Sync Refresh Interval advanced setting for each subscribed library.
- F . Add a new subscriber library from each vSphere environment.
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?
- A . Two new Fibre Channel storage arrays will be deployed, one at either site. Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays.
- B . Two new vSphere clusters enabled with vSAN will be deployed, one at either site. vSAN will be used to provide policy-based management for each application tier.
vSphere Replication will be used to replicate the virtual machine data in an asynchronous configuration. - C . Two new ISCSI storage arrays will be deployed, one at either site.
Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays. - D . Two new storage arrays will be deployed, one at either site.
vSphere Volumes (vVOLs) will be used to provide policy-based management for each application tier. Data replication will be offloaded to the new arrays.
An architect is designing a new backup solution for a vSphere platform that has been recently upgraded to vSphere 7.
The architect wants the backup solution to perform the following:
✑ Full virtual machine image backup and restore
✑ Incremental virtual machine image backup and restore
✑ File level backup and restore within both Windows and Linux virtual machines
✑ LAN-free backup
