NEW QUESTION # 37
An architect makes the design decision to install ESXi on embedded and resilient 8 GB SD cards.
What is the impact of this design decision?
- A. Host profiles must be used for this kind of installation
- B. The size of the SD cards is too small and the installation will fail
- C. Scratch partition would need to be created on the external storage
- D. The vSphere Auto Deploy feature must be enabled on vCenter Server
Answer: C
Explanation:
https://kb.vmware.com/s/article/2074026 You can store coredumps on the SD boot media, but refrain from configuring the scratch partition here as the logs are write intensive and can cause the SD card to fail faster resulting in re-installation of ESXi
https://blogs.vmware.com/vsphere/2021/09/esxi-7-boot-media-consideration-vmware-technical-guidance.html A configuration involving the usage of SD card or USB drives as boot media is a minimum of 8 GB SD card or USB drive + Locally attached persistent storage device for ESX-OSData partition may be used but is also not recommended. Recommended list of locally attached storage devices are listed below.In any case, if an SD or USB device is used for boot media (only SD/USB or SD/USB + local HDD/SSD disk), follow the below instructions to reduce the amount of IO sent to the SD or USB boot media:Enable the ToolsRamDisk option to offload VMTools install/upgrade IO requests on the RAM disk.Ensure the /scratch partition is configured on persistent storage like a local HDD/SSD or boot from the SAN device.

NEW QUESTION # 46
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.)
- A. The backup service will store data in a secure facility
- B. The clusters will have a minimum redundancy of N+1
- C. The customer will update their hardware standard to support rack mount servers
- D. The backup service has sufficient capacity for the new requirements
- E. All virtual machines will be deployed with the same resource profile for production and development

NEW QUESTION # 48
An architect is reviewing a physical storage design. The customer has specified that a new active-passive based storage array will be used to provide storage for the vSphere clusters.
Which configuration should for the architect recommended?
- A. VMW_PSP_MRU
- B. VMW_SATP_DEFAULT_AA
- C. VMW_PSP_FIXED
- D. VMW_SATP_LOCAL
Answer: A
Explanation:
The Most Recently Used (VMware) policy is enforced by VMW_PSP_MRU. It selects the first working path discovered at system boot time. The Most Recently Used policy does not use the preferred path setting. This policy is default for most active-passive storage devices. https://docs.vmware.com/en/VMware-vSphere/6.7/vsphere-esxi-vcenter-server-671-storage-guide.pdf

NEW QUESTION # 55
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. 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.
- B. Migrate the acquired company's virtual machines into the vSphere environment as it will currently fit.
- C. Purchase extra hosts to add to the cluster in anticipation of adding the acquired company's virtual machines.
- D. Use the current budget to add memory to the cluster to increase each ESXi host's capacity and add the new virtual machines.
Answer: D
