Which four factors should an architect consider when calculating the number of hosts required for a
new multi-site vSphere-based solution that utilizes external storage? (Choose four.)
A, B, D, G
Explanation:
The workload profile (CPU and memory) of each workload
Understanding the CPU and memory requirements for each workload is crucial for determining the
capacity needed on each host. This helps ensure that each host has sufficient resources to run the
virtual machines (VMs) efficiently.
The amount of resources required for virtual machine (VM) swap and VM snapshots
VM swap files and snapshots require additional storage and compute resources. It's important to
account for these resource requirements to avoid overloading the hosts or running into resource
bottlenecks.
The number of existing workloads that will be migrated onto the new solution
Knowing how many workloads will be migrated allows the architect to estimate the total resource
demand and determine the number of hosts required to support the migrated workloads effectively.
The hardware specification of the underlying infrastructure
The hardware specifications of the hosts, including the CPU, memory, storage, and network
interfaces, play a significant role in determining how many hosts are needed to support the
workloads. More powerful hardware may reduce the number of hosts required, while less capable
hardware might increase the number needed.
An architect is designing a backup solution.
Which two statements should be included in the logical design for this solution? (Choose two.)
A, E
Explanation:
The database must be backed up every day during the maintenance window of 1:00AM and 3:00AM.
This is a logical design requirement because it specifies the timing for the backup operations. It's
important to define backup schedules to align with the maintenance window, ensuring minimal
disruption to production workloads.
The database will be backed up using an API-based backup solution.
This is a logical design decision that specifies the method of backup. Using an API-based backup
solution is a modern, efficient way to ensure consistent and application-aware backups of databases.
An architect is tasked with helping a customer develop a design that meets the following
requirements:
Must have no single point of failure
Must include thorough standard operating procedure documentation
Must use VMXNET3 virtual network interface card
Must have 99.9% uptime Service Level Agreement
Must use the latest version of VMware vSphere
Which two are considered constraints? (Choose two.)
A, C
Explanation:
Must use the latest version of VMware vSphere
This is a constraint because the design must adhere to the specific requirement of using the latest
version of VMware vSphere. This limits the possible versions or features that can be incorporated
into the solution.
Must use VMXNET3 virtual network interface card
This is also a constraint because it mandates the use of a specific virtual network interface card
(VMXNET3), restricting the design to that particular choice for network connectivity.
A company has the requirement to ensure that business-critical applications have the necessary
network bandwidth to function optimally and maintain a consistent quality of service (QoS).
Which statement would be included in the conceptual design to support this requirement?
A
Explanation:
This statement supports the requirement for ensuring that business-critical applications have the
necessary network bandwidth and maintain consistent quality of service (QoS). By creating a
distributed switch and enabling Network I/O Control, you can prioritize network traffic and ensure
that the necessary bandwidth is allocated to critical applications, improving their performance and
quality of service.
An architect is designing the virtual networking components of a vSphere-based solution that will
provide an environment for the development of a new latency sensitive stock trading application.
The following information was identified within the initial meeting with the customer:
The customer has vCenter Standard and vSphere Standard licenses left over from a previous project.
The customer's CFO has approved budget for additional purchases, if required.
The following requirements were also identified during the meeting:
The solution must support 500 development workloads concurrently running in the secondary site.
The solution must support the ability to complete all vSphere Operational Management centrally.
The solution must ensure business-critical applications are not impacted by vSphere system-level
operations.
Given the requirements, the architect has decided on a single 20-node cluster for development.
Which three additional design decisions should the architect make to meet these requirements?
(Choose three.)
B, E, F
Explanation:
The solution will deploy VMware vSphere Enterprise Plus on all hosts within the cluster.
VMware vSphere Enterprise Plus offers advanced networking and storage features that will support
the required high availability, performance, and management capabilities. Features such as
Distributed Switches and Network I/O Control (NIOC) are critical to meeting the business-critical
application and performance requirements for the latency-sensitive stock trading application.
The solution will deploy a single vSphere Distributed Switch with each host connected to it.
A vSphere Distributed Switch (VDS) is ideal for managing network configurations centrally across
multiple hosts, which meets the requirement for centralized vSphere operational management. It
also ensures consistent network configurations and simplifies network management at scale.
The solution will configure Network I/O control to ensure that system-level bandwidth does not
impact workload network traffic.
Network I/O Control (NIOC) is essential for prioritizing network traffic, ensuring that latency-
sensitive workloads are not impacted by other system-level or less critical traffic. This is crucial for
the performance requirements of the stock trading application.
An architect is designing a new vSphere-based solution for a customer.
During a requirements gathering workshop, the following information is provided:
0The solution must have a primary and secondary (isolated) environment
The solution must support orchestration to address application dependencies
The isolated environment must be able to scale on demand in case of a DR scenario
The solution is managed through a single interface
Which solution should the architect include in this design?
B
Explanation:
This solution aligns with the requirements of having a primary and secondary isolated environment,
orchestration of application dependencies, the ability to scale on demand in a disaster recovery (DR)
scenario, and a single interface for management. VMware Cloud on AWS integrates with VMware's
vSphere environment and offers orchestration for DR, as well as the flexibility to scale resources on
demand in the event of a DR scenario. It also provides a unified management interface through
vCenter.
An architect is holding a requirements workshop with a customer for a new vSphere solution design.
The customer states that the solution should make it easy to identify and apply patches or updates to
ESXi hosts, including the ability to pre-stage the files on the ESXi hosts.
Which design quality is being referenced by the customer?
B
Explanation:
The customer's requirement for making it easy to identify and apply patches or updates to ESXi
hosts, including pre-staging the files, is focused on simplifying the management of the vSphere
environment. This is a key aspect of manageability, which refers to the ease with which IT
administrators can handle tasks like patching, updates, and configuration management in a
consistent and efficient manner.
An architect is designing a new vSphere-based solution for a customer.
During a requirements gathering workshop, the following information is provided:
The solutions must provide a recovery point objective (RPO) of 15 minutes.
The solution must have a primary and secondary site.
The solution must support orchestration to address application dependencies.
Which two solutions should the architect include in the design to meet these requirements? (Choose
two.)
A, C
Explanation:
vSAN stretched cluster
A vSAN stretched cluster provides high availability and disaster recovery capabilities across two sites.
It supports RPOs of 15 minutes or less and ensures data is replicated synchronously between the
primary and secondary site, meeting the recovery point objective (RPO) requirement. It also allows
orchestration and application dependencies to be managed effectively between sites.
Site Recovery Manager
Site Recovery Manager (SRM) provides automation and orchestration of disaster recovery processes,
ensuring that workloads can be recovered in a secondary site while maintaining the RPO and
recovery time objective (RTO). It can integrate with various replication technologies, including
vSphere Replication, and ensures that application dependencies are addressed in the recovery
process.
An architect is designing a vSphere-based private cloud solution to support the following customer
requirements:
The solution should support running 5,000 concurrent production compute workloads across the
primary and secondary sites.
The solution should support running 1,000 development compute workloads within the secondary
site.
The solution should support up to 50 management workloads across the primary and secondary site.
The solution must ensure the isolation of virtual infrastructure management operations between
management and compute workloads.
The solution must ensure that the hosting of any virtual infrastructure management workloads does
not impact the amount of capacity available for compute workloads.
The solution must ensure that all production compute workloads are physically isolated from
development compute workloads.
The solution must ensure that the operational management of compute workloads in the secondary
site is possible in the event of a disaster affecting the primary site.
How many VMware vCenter instances will the architect need to include in the design to meet these
requirements?
B
Explanation:
To meet the requirements outlined, the architect will need to design a solution with three VMware
vCenter instances. Here's why:
Isolation of Virtual Infrastructure Management Operations: The management workloads (such as
vCenter itself, along with other virtual infrastructure management tools) should be isolated from
compute workloads. This suggests the need for a separate vCenter instance to manage the
infrastructure without impacting compute workloads.
Physical Isolation of Production and Development Workloads: Production workloads and
development workloads need to be physically isolated, which suggests the need for different vCenter
instances to maintain separation.
Support for Operational Management in the Event of a Disaster: In the event of a disaster affecting
the primary site, the secondary site should still be able to manage compute workloads. This could be
achieved by having a vCenter instance in each site (primary and secondary) to ensure continued
management in the event of a failure.
Breakdown of the three vCenter instances:
vCenter 1: Manages production workloads across both primary and secondary sites.
vCenter 2: Manages development workloads in the secondary site, ensuring isolation from
production.
vCenter 3: Manages the virtual infrastructure management workloads, ensuring isolation from
compute workloads.
An architect is creating the design for a vSphere platform that will be used as the target for a
migration from multiple legacy vSphere platforms that are being decommissioned. The customer has
provided the following information:
Each legacy platform has its own set of virtual machine templates stored in OVF format.
All of the templates need to be migrated to the new platform.
After migration, the templates should be centralized into a single location.
The templates must be accessible to all clusters in the new platform vCenter instance.
Any new templates added to the central location must be automatically available to all clusters.
Administrators must be able to deploy new virtual machines directly from the template instances.
The customer also confirmed that after the migrations are complete, the new platform will be the
only vSphere solution available.
Which design choice should the architect evaluate in the logical design for the storage and
management of virtual machine templates?
C
Explanation:
A subscribed content library is the best design choice for managing and centralizing virtual machine
templates in this scenario. Here's why:
Centralized Management: A subscribed content library allows templates to be stored in a central
location and made available to all clusters within the vCenter instance. Any new templates added to
the central content library are automatically made available to all subscribed clusters, meeting the
requirement for templates to be centrally stored and easily accessible by all clusters.
Automatic Updates: When a new template is added to the central content library, it becomes
automatically available to all clusters that subscribe to it, fulfilling the requirement for automatically
available new templates.
VM Template Deployment: Administrators can deploy new virtual machines directly from the
template instances stored in the content library, which ensures that the deployment process is
streamlined and consistent.
