Question 1

A company has the requirement of ensuring 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 logical design to support this requirement?

AThe network infrastructure must ensure secure communications and efficiently use available bandwidth.

BNetwork resource pool named 'bca-pool-02' is given a reservation quota of 5Gbit/sec.

CThe distributed switch will use a minimum of 25Gbps Ethernet.

DA distributed virtual switch will be created and Network I/O Control will be enabled.

Answer : D

Network I/O Control (NIOC) is a key feature available with distributed virtual switches (vDS) that allows administrators to prioritize and allocate bandwidth to specific network traffic types. It ensures that business-critical applications receive the necessary bandwidth and maintain a consistent quality of service (QoS). This solution meets the requirement to ensure optimal network bandwidth allocation and service consistency.

Question 2

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 15minutes.

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.)

AvSAN stretched cluster

BvSphere HA

CSite Recovery Manager

DvSphere Fault Tolerance

EvSphere Replication

Answer : A, C

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.

Question 3

An architect is documenting the design decisions for a new vSphere solution. The following design decision has been made:

Create a separate vSphere cluster for the management workloads

What could the architect include as justification for this design decision?

AThis increases operational overhead as multiple clusters are required for management and compute workloads.

BThis increases capital expenditure as hardware must be purchased for multiple clusters.

CThis ensures that compute workloads have no impact on the management workloads.

DThis ensures that compute workloads have no impact on the management workloads.

Answer : C

Creating a separate vSphere cluster for management workloads ensures that these workloads, which are critical for monitoring, managing, and orchestrating the environment, do not compete for resources with compute workloads. This separation enhances the stability and reliability of management functions, even during periods of high resource utilization by compute workloads.

Question 4

Following a review of security requirements, an architect has confirmed the following requirements:

Which three requirements would be classified as technical (formerly non-functional) requirements? (Choose three.)

AA clustered firewall solution must be placed at the perimeter of the hosting platform, and all ingress and egress network traffic will route via this device.

BA distributed firewall solution must secure traffic for all virtualized workloads.

CThe hosting platforms security information and event management (SIEM) system must be scalable to 20,000 events per second.

DThe hosting platforms storage must be configured with data-at-rest encryption.

EThe hosting platform limits access to authorized users.

FAll virtualized workload, hypervisor, firewall and any management component system events must be monitored by security administrators.

Answer : A, C, D

A clustered firewall solution must be placed at the perimeter of the hosting platform, and all ingress and egress network traffic will route via this device:

This is a technical requirement because it specifies how network traffic is to be managed through a specific infrastructure element (the firewall). It outlines how the security device is implemented in the network architecture.

The hosting platform's security information and event management (SIEM) system must be scalable to 20,000 events per second:

This is a technical requirement because it deals with the scalability and performance of the SIEM system. It specifies how the system must handle a large volume of data, which is a technical characteristic of the infrastructure.

The hosting platform's storage must be configured with data-at-rest encryption:

This is also a technical requirement because it defines how the data should be stored securely, which is an implementation detail. It specifies that encryption needs to be applied to stored data, a feature related to storage infrastructure.

Question 5

An architect is documenting the design for a new vSphere cluster. The customer provides the following information:

All ESXi hosts will use hardware from the same vendor

All ESXi hosts will be monitored for hardware related issues using the vendor's monitoring tooling

The vendor's monitoring tooling provides a plugin for vCenter to allow the hardware status to be visible

The customer also informs the architect of the following requirements:

Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded.

Workloads must be automatically restarted on other hosts in the event of a host failure.

What should the architect include in the design to meet these requirements?

AvSphere HA will be enabled and set to Power off and Restart VMs in response to a host isolation.
Proactive HA will be enabled with an Automation Level of Automated.

BvSphere HA will be enabled and set to Power off and Restart VMs in response to a host isolation.
VM Monitoring will be enabled with a setting of VM Monitoring.

CvSphere HA will be enabled and set to restart VMs in response to a host failure.
VM Monitoring will be enabled with a setting of VM and Application Monitoring.

DvSphere HA will be enabled and set to restart VMs in response to a host failure.
Proactive HA will be enabled with an Automation Level of Automated.

Answer : D

To meet the customer requirements, we need to address the two specific scenarios:

Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded:

This requirement can be fulfilled by Proactive HA. Proactive HA is a feature of vSphere HA that works in conjunction with hardware health monitoring tools, such as the vendor's plugin for vCenter. When the vendor's monitoring tool marks a host as degraded (due to hardware issues), Proactive HA can automatically trigger the migration of workloads to other hosts, based on the Automation Level configuration.

Workloads must be automatically restarted on other hosts in the event of a host failure:

This can be managed using vSphere HA with the setting to restart VMs when a host fails. This ensures that in the event of a host failure, workloads are automatically restarted on available hosts in the cluster.

By enabling Proactive HA with an Automation Level of Automated, the architect ensures that degraded hosts are automatically handled (through workload migration) without manual intervention.

Question 6

As part of designing a greenfield vSphere-based hosting solution, an architect is responsible for defining a patch management solution for the virtual infrastructure.

During initial meetings with the customer, the following information is provided:

There are two geographically dispersed physical sites (primary and secondary) in scope for the solution.

The inter-site connectivity has been classified as low bandwidth and high latency.

The customer has the following requirements:

REQ001 - Only IT Security Team-approved versions of VMware Tools should be installed across all workloads within the infrastructure.

REQ002 - The solution should minimize traffic across the inter-site link.

REQ003 - Upgrades to the virtual infrastructure should continue in the event of a failure with either site.

A combination of which three design decisions could the architect make to ensure the requirements are met? (Choose three.)

AThe solution will set the UserVars.ToolsRamdisk advanced system setting on each VMware ESXi host to '1' (enabled).

BThe solution will ensure that all VMware ESXi hosts within a site have access to the local VMFS datastore containing the shared VMware Tools repository.

CThe solution will use VMware Autodeploy to ensure the latest version of VMware Tools is deployed to each workload.

DThe solution will set the UserVars.ProductLockerLocation advanced system setting on each VMware ESXi host to point to the local site shared Repository

EThe solution will create a shared repository on a VMFS datastore within each site that contains all approved versions of VMware Tools.

FThe solution will create a shared repository on a VMFS datastore within the primary site that contains all approved versions of VMwareTools.

Answer : B, D, E

The solution will ensure that all VMware ESXi hosts within a site have access to the local VMFS datastore containing the shared VMware Tools repository.

This decision ensures that each site has local access to the VMware Tools repository, which minimizes traffic across the low-bandwidth, high-latency inter-site link. By keeping the repository within each site, the local ESXi hosts can access the repository without needing to traverse the inter-site link frequently.

The solution will set the UserVars.ProductLockerLocation advanced system setting on each VMware ESXi host to point to the local site shared repository.

This ensures that each ESXi host points to the local site repository for VMware Tools. This approach minimizes inter-site traffic by ensuring that all updates and patches are performed using local resources, avoiding the need to transfer VMware Tools files over the low-bandwidth, high-latency connection.

The solution will create a shared repository on a VMFS datastore within each site that contains all approved versions of VMware Tools.

This decision ensures that both sites have a local copy of the approved VMware Tools versions, in line with REQ001, which mandates that only IT Security Team-approved versions of VMware Tools should be installed. Additionally, it minimizes inter-site traffic, as both sites will use their local repositories.

Question 7

An architect is creating a design for a new vSphere solution to meet the following business requirement:

REQ001 - Reduce operational expenditure

Which design decision could the architect include in the logical design to satisfy this requirement?

AUse vSphere Standard licenses on all clusters.

BUse heterogeneous hardware for the hosts in all clusters.

CUse vSphere Lifecycle Manager on all clusters.

DUse an N + 1 design to define the required capacity on all clusters.

Answer : C

vSphere Lifecycle Manager helps reduce operational expenditure (OPEX) by automating the patching and management of the vSphere environment. It provides centralized management for host updates, ensuring consistency across the environment and reducing the manual effort required for ongoing operations. This leads to reduced operational overhead, which directly addresses the requirement to reduce OPEX.
