QUESTION: 11

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.)

The workload profile (CPU and memory) of each workload
The amount of resources required for virtual machine (VM) swap and VM snapshots
The number of existinq workloads that will be decommissioned prior to the completion of project
The number of existinq workloads that will be miqrated onto the new solution
The number of network connections per physical host server
The future physical location of any workloads
The hardware specification of the underlying infrastructure

Answer(s): 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.

QUESTION: 12

An architect is designing a backup solution.

Which two statements should be included in the logical design for this solution? (Choose two.)

The database must be backed up even/ day during the maintenance window of 1:00AM and
3:00AM.
The network that will be used for backups will be configured to use VLAN ID 1511.
The bkp-nfs-01 datastore will be used for backups.
The company's existing backup solution will be unsupported by the third-party vendor in six months.
The database will be backed up using an API-based backup solution.

Answer(s): 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.

QUESTION: 13

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.)

Must use the latest version of VMware
Must have no single point of failure
Must use VMXNET3 virtual network interface card
Must include thorough standard operating procedure documentation
Must have 99.9% uptime Service Level Aqreement

Answer(s): 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.

QUESTION: 14

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 distributed switch will be created and Network I/O Control will be enabled.
The network infrastructure must ensure secure communications and efficiently use available bandwidth.
Network resource pool named "bca-pool-02" is given a reservation quota of 5 Gbit/sec.
The distributed switch will use a minimum of 25 Gbps Ethernet.

Answer(s): 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.

QUESTION: 15

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.)

The solution will configure Traffic Shaping policies to restrict network bandwidth on ingress and egress.
The solution will deploy VMware vSphere Enterprise Plus on all hosts within the cluster.
The solution will deploy VMware vSphere Standard on all hosts within the cluster.
The solution will deploy a single VMware Standard Switch that will be configured identically on each host.
The solution will deploy a single vSphere Distributed Switch with each host connected to it.
The solution will configure Network I/O control to ensure that system-level bandwidth does not impact workload network traffic.

Answer(s): 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.
