A company is expanding an existing vSphere deployment to meet new demands from the business. The following requirements have been identified for the expanded infrastructure:REQ01- It must support enhanced vMotion compatibility (EVC) mode for Intel "Nehalem" Generation (Intel Xeon Core i7) processors.REQ02- It must be accessible via an API.REQ03- It must support a variety of operating systems.REQ04- It must notify administrators whenever a virtual machine is connected to more than one network.Which requirement would be classified as a technical (formerly non-functional) requirement?
Answer(s): C
This is a technical (formerly non-functional) requirement because it specifies a particular feature (EVC mode for specific processor generations) that the infrastructure must support to ensure compatibility across the vSphere environment. This requirement addresses a technical aspect of how the environment will function but does not directly relate to business functionality.
An architect is designing a new vSphere solution. The customer has provided the following information to describe how the solution will be used:The solution will host development workloadsAdministrators will utilize snapshots frequently, with snapshots sometimes retained for extended periods of timeSome of the workloads are sensitive to latency on the I/O of the storageStorage for the workloads will be provided by a physical arrayThe physical array does not include a storage providerAll workloads must be hosted on the solution, there are no other vSphere environments available for useWhich design decision should the architect make to meet the needs of the customer?
Answer(s): A
VAAI (vSphere APIs for Array Integration) improves storage performance and offloads certain tasks (such as cloning, snapshots, and more) directly to the storage array. This is important because the customer will be utilizing snapshots frequently, and VAAI can help accelerate snapshot operations, reducing the impact on the ESXi host and improving overall performance.Since the physical array does not include a storage provider and does not support vSphere Storage APIs - Storage Awareness (VASA) or Virtual Volumes (vVols), the solution should focus on using VMFS datastores with a VAAI-capable storage array. This setup allows better performance for snapshot operations and other storage tasks.
An architect has been tasked with designing a greenfield hosting platform.As part of a workshop, it is identified that the new solution must support the following:Provide a centralized way to enforce virtual network security policyProvide network security for both virtual machines and containerized applicationsDeny network access between all workloads by defaultLinked services should be connected to the same virtual port groups by defaultSupport for the security teams network monitoring solutionWhich elements should the architect include in the design to meet the identified requirements?
Answer(s): D
VMware NSX: NSX provides a centralized platform for network virtualization and security, which aligns with the requirement for enforcing virtual network security policies. It can manage network segmentation, security policies, and micro-segmentation across the entire environment, including both virtual machines and containerized applications.Distributed Firewalls: NSX's distributed firewall allows for micro-segmentation, meaning that network access is denied between workloads by default, and access controls can be applied based on security policies. This meets the requirement of denying network access by default.Port Mirroring: Port mirroring in NSX can integrate with the security team's network monitoring solutions. It enables the security team to capture traffic for monitoring and analysis, addressing the requirement for network monitoring support.
An architect has made the following assumptions:The customer will provide licensing for the vSphere platform.The storage hardware has sufficient capacity for future workload scale.The data center offers sufficient power, cooling and rack space for workload scale.Which two risks must be documented in the design document in response to these assumptions? (Choose two.)
Answer(s): B,D
The storage may not have capacity to accommodate 20% year-over-year virtual machine growth.This is a risk because, while the assumption is that the storage hardware has sufficient capacity, there is a possibility that the hardware may not be able to support future growth, especially if the customer's workload grows faster than expected. Documenting this risk ensures that the design considers potential capacity constraints.The customer may not have an existing licensing subscription that covers features the architect intends to use.This is a risk because although the assumption is that the customer will provide licensing, there may be discrepancies between the features required for the design and the customer's existing licensing. This risk ensures that the architect verifies that the customer's licensing aligns with the solution requirements.
An architect is designing the datastore configuration of a new vSphere-based solution.The following information was obtained during the initial meeting with the customer:There is currently 500 production and DMZ virtual machine workloads spread evenly across the primary and secondary site.The profile of the workloads (per site) is as follows:- DMZ:-- 75 x Small: 1 vCPU, 2GB RAM, 200 GB disk- Production:-- 50 x Small: 1 vCPU, 2 GB RAM, 200 GB disk-- 100 x Medium: 2 vCPU, 4 GB RAM, 200 GB disk-- 25 x Large: 4 vCPU, 8 GB RAM, 500 GB diskThe average IO Profile per workload is 70/30 read/write.The solution should cater to 10% storage growth in the first year.The solution should cater to 15% virtual machine snapshot overhead.The storage team has confirmed:- A scalable external storage array has been deployed per site to support the storage requirements.- The storage array will connect to all hosts using a dedicated Fibre Channel storage area network fabric.- Usable storage capacity is available in 10 TB LUNs.- As many LUNs as required can be provided.- Every effort should be made to ensure the number of required LUNs is minimized.The security team has stated that all DMZ and production workloads must remain logically isolated from each other.Given the information provided, which three design decisions should the architect make to meet the requirements? (Choose three.)
Answer(s): A,C,D
Six 10TB VMFS datastores will be configured on each site for all production workloads.This choice is based on the need to distribute production workloads across multiple datastores while ensuring that each datastore is large enough to accommodate the space required by the workloads. Given the average sizes of the virtual machines and the growth and snapshot overhead, six 10TB VMFS datastores would be appropriate for production workloads, ensuring scalability while minimizing the number of LUNs.Each 10TB LUN will be configured as a VMFS datastore.VMFS (Virtual Machine File System) is the standard choice for vSphere environments when using Fibre Channel LUNs. It provides the necessary features, such as concurrency and high-performance access, for production workloads. This option is appropriate given that the storage array uses Fibre Channel for connection and VMFS is the standard file system for such configurations.Two 10TB VMFS datastores will be configured on each site for all DMZ workloads.The DMZ workloads are smaller in number and storage requirements compared to the production workloads, so configuring two 10TB VMFS datastores for DMZ workloads will provide enough capacity while maintaining logical isolation. This approach also minimizes the number of LUNs required to meet the storage growth needs.
