Question 1

An architect is responsible for the following customer considerations in a hardware refresh:

Capacity planning will ensure that the environment does not exceed 70% of peak-average utilization on deployment.

CPU purchases will favor clock speed and last level cache over cores per socket.

Additional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70% for 3 consecutive business days.

Path Selection policy will be set to round robin and set to switch paths with every SCSI command.

vCPU to pCPU ratio may not exceed 5:1.

What are three considerations when designing for performance? (Choose three.)



Answer : B, E, F

vCPU to pCPU ratio may not exceed 5:1.

This ensures that the virtual CPU (vCPU) allocation is balanced with the physical CPU (pCPU) resources. A ratio that exceeds 5:1 can lead to CPU contention, negatively impacting performance. By maintaining this ratio, the architect ensures that the workloads have sufficient CPU resources for optimal performance.

CPU purchases will favor clock speed and last level cache over cores per socket.

This is an important performance consideration. Choosing CPUs with higher clock speed and larger last-level cache (LLC) ensures that workloads requiring higher single-threaded performance are optimized. This decision favors workloads that benefit from faster CPU processing and larger cache sizes, improving overall performance.

Additional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70% for 3 consecutive business days.

This performance-related decision ensures that the environment remains responsive under load. Adding additional hosts when resource utilization exceeds thresholds helps prevent bottlenecks and ensures continued optimal performance by distributing workloads across more physical hosts.


Question 2

During a workshop for a design project, the following information is shared:

Develop and maintain strong relationships with key stakeholders and partners to promote collaboration.

Maintain high standards of quality and professionalism in all aspects of the project.

Build a strong foundation for future projects, including cloud infrastructures.

Ensure project timelines and milestones are met by effectively managing resources and priorities.

Which of these would be classified as a business outcome of the project?



Answer : A

A business outcome refers to a result or impact that directly contributes to the strategic goals of the organization, typically focusing on long-term objectives or future benefits. In this case, building a strong foundation for future projects, including cloud infrastructures, aligns with the business goal of positioning the organization for future success and scalability. This outcome is about preparing the organization for the future, which is a key business-driven result.


Question 3

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:

REQ001- It must support enhanced vMotion compatibility (EVC) mode for Intel "Nehalem" Generation (Intel Xeon Core i7) processors.

REQ002- It must be accessible via an API.

REQ003- It must support a variety of operating systems.

REQ004- 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 : 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.


Question 4

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.)



Answer : A, C

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.


Question 5

An architect will be updating an existing vSphere data center design.

The following information has been provided:

The new design must carry over existing VLANs for workloads.

The networking for storage must not share the data path with workload traffic.

The new design must be able to add additional VLANS.

The new design must reduce management overhead.

The new replacement servers have two 100GB network cards.

Which design will meet the requirements for existing workload networks and allow scaling of additional networks?



Answer : D

The customer's requirements include the following:

Carry over existing VLANs for workloads: This can be easily achieved with a vSphere distributed switch (VDS), as it supports the configuration of VLANs and ensures that they can be applied to multiple ESXi hosts across the data center.

Networking for storage must not share the data path with workload traffic: By using aggregated uplinks in the VDS configuration, the architect can easily separate workload traffic and storage traffic by using different uplinks or VLANs. Aggregated uplinks ensure that there is sufficient bandwidth for both workloads and storage, while keeping them logically separated in terms of traffic management.

Add additional VLANs: A VDS supports the dynamic addition of VLANs. New VLANs can be added and managed centrally, reducing the complexity and management overhead when scaling the network.

Reduce management overhead: The use of a single VDS significantly reduces management complexity compared to managing multiple vSphere standard switches (VSS). With VDS, network configuration and management are centralized and simplified across all ESXi hosts.

Given that the new replacement servers have two 100 GB network cards, the aggregated uplinks in a VDS configuration will provide the required network capacity while ensuring that traffic is properly segmented and scalable.


Question 6

An architect is updating the design for a vSphere environment.

During a workshop focused on security, the following has been identified:

It has been determined that any configuration of ESXi hosts can only be completed via VMware vCenter

The Direct Console User Interface (DCUI) service must be disabled on ESXi hosts

The SSH service must be disabled on ESXi hosts

Based on the information from the workshop, which element does the architect need to include in the design?



Answer : A

Strict Lockdown Mode is the correct choice because it restricts all access to the ESXi host directly, ensuring that configuration can only be performed through VMware vCenter. This is in line with the requirement that configuration can only be done via vCenter.

Strict Lockdown Mode disables the Direct Console User Interface (DCUI) and SSH services, which aligns with the customer's requirement to have these services disabled for security purposes.


Question 7

A company has a requirement that all production applications must have a maximum tolerable downtime (MTD) of one hour per month.

Which statement would be included in the physical design to support this requirement?



Answer : B

To meet the requirement of a maximum tolerable downtime (MTD) of one hour per month for production applications, the solution must ensure high availability and quick recovery of virtual machines (VMs) in the event of a host failure. Enabling vSphere High Availability (HA) with the Host Failure Response set to Restart VMs will automatically restart VMs on other hosts within the cluster in the event of a host failure. This minimizes downtime and helps meet the MTD requirement by ensuring minimal disruption to production workloads.
