NEW QUESTION # 31
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. All virtual machines will be deployed with the same resource profile for production and development
- B. The customer will update their hardware standard to support rack mount servers
- C. The clusters will have a minimum redundancy of N+1
- D. The backup service will store data in a secure facility
- E. The backup service has sufficient capacity for the new requirements
Answer: C,E
NEW QUESTION # 32
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?
- A. Manageability
- B. Recoverability
- C. Availability
- D. Security
Answer: A
NEW QUESTION # 33
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. Encrypted channels must be used for all communications.
- C. Communications must be through Private VLANs (PVLAN).
- D. Unauthorized access to interfaces must be reported within 15 minutes.
Answer: C
Explanation:
For example:
"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 # 34
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. The vSphere Auto Deploy feature must be enabled on vCenter Server
- D. Scratch partition would need to be created on the external storage
Answer: D
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.

- B. The customer will update their hardware standard to support rack mount servers
- C. The clusters will have a minimum redundancy of N+1
- D. The backup service will store data in a secure facility
- E. The backup service has sufficient capacity for the new requirements
Answer: C,E
Explanation:
B) The backup service has sufficient capacity for the new requirements
"All virtual machine backups must be completed using the existing backup service." The existing backup service may not have capacity or compatabiltiy for the new SDDC E) The clusters will have a minimum redundancy of N+1
"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" We assume N+1 is sufficient. They may require a higher level of redundancy.
