An architect is documenting the design for a new multi-site vSphere solution. The customer has informed the architect that the workloads hosted on the solution are managed by application teams, who must perform a number of steps to return the application to service following a failover of the workloads to the secondary site. These steps are defined as the Work Recovery Time (WRT). The customer has provided the architect with the following information about the workloads:
Critical workloads have a WRT of 12hours
Production workloads have a WRT of 24hours
Development workloads have a WRT of 24hours
All workloads have an RPO of 4hours
Critical workloads have an RTO of 1hour
Production workloads have an RTO of 12hours
Development workloads have an RTO of 24hours
The customer has also confirmed that the Disaster Recovery solution will not begin the recovery of the development workloads until all critical and production workloads have been recovered at the secondary site.
What would the architect document as the maximum tolerable downtime (MTD) for each type of workload in the design?
The Maximum Tolerable Downtime (MTD) is the maximum time that an application or system can be unavailable before it negatively impacts the business. The MTD is calculated by adding the Recovery Time Objective (RTO) to the Work Recovery Time (WRT). Here's how it applies to each workload type:
- RTO: 1 hour (time to restore the system to a usable state after failure).
- WRT: 12 hours (the time to get the application fully back to service).
- MTD = RTO + WRT = 1 hour + 12 hours = 13 hours.
- RTO: 12 hours (time to restore the system to a usable state after failure).
- WRT: 24 hours (time to get the application fully back to service).
- MTD = RTO + WRT = 12 hours + 24 hours = 36 hours.
- RTO: 24 hours (time to restore the system to a usable state after failure).
- WRT: 24 hours (time to get the application fully back to service).
- MTD = RTO + WRT = 24 hours + 24 hours = 48 hours.
An architect is designing a new vSphere solution. The following information has been gathered during the design workshops with the customer:
The solution will be deployed into two availability zones (AZs)
The solution will be configured as a single stretched cluster with shared storage across the two AZs
Production and Development workloads will run across both AZs
The cluster is configured as N + 1
The architect needs to ensure that, in the event of a host failure during maintenance of another host in the cluster, only the Production workloads are recovered.
What should the architect include in the design to meet this requirement?
In this scenario, the requirement is to ensure that only Production workloads are recovered in the event of a host failure during maintenance, while Development workloads are not restarted. This can be achieved using vSphere HA settings.
By configuring the vSphere HA Host Failure Response to Restart VMs, the system will attempt to restart VMs when a host failure occurs.
Setting the Restart Priority for Development VMs to Disabled ensures that these VMs will not be restarted during a failure event, even though the cluster is set to restart VMs in the event of a host failure. This way, only the Production workloads will be restarted, meeting the customer's requirement.
An architect is responsible for extending the hosting design for a customer. The customer has a mission-critical 3-node application which is load balanced in an active/active/passive configuration. The application administrator requests that the virtual infrastructure team be responsible for maintaining platform level availability. An organizational policy exists to mandate the highest possible availability for mission-critical applications.
Based on the resource requirements, the architect has made the following design decision:
The target vSphere cluster contains three VMware ESXi host servers
A combination of which additional four physical design decisions should the architect make to maximize availability of the application? (Choose four.)
The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.
Creating a VM-Host Affinity rule ensures that specific workloads are restricted to certain hosts, which can be useful to avoid placing critical applications on hosts that may not meet their availability requirements.
The solution will enable vSphere High Availability (HA) with restart priority set to 'Highest' for the application virtual machines.
Enabling vSphere HA ensures that virtual machines are automatically restarted on other hosts in the event of a host failure. Setting the restart priority to 'Highest' for mission-critical VMs ensures that these VMs will have the highest priority for restart if any issues arise.
The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.
Enabling vSphere Fault Tolerance (FT) ensures that the application VMs are fully protected by creating a live shadow VM that runs in lockstep with the primary VM. In the event of a host failure, the shadow VM will take over instantly, providing continuous availability for the application.
The solution will create a virtual machine DRS group that contains all of the critical application workloads.
Creating a virtual machine DRS (Distributed Resource Scheduler) group for critical workloads ensures that these VMs are placed and migrated to the optimal hosts based on the cluster's resource requirements, improving availability and performance.
What is an example of an availability design quality?
Availability design quality refers to the capacity of a system or infrastructure to remain operational, minimizing downtime, and ensuring continuous service delivery, especially in the event of a failure. The concept of N + 1 redundancy ensures that if one component fails (such as a host or a power supply), there is always an additional, spare component available to take over the workload, maintaining the system's availability.
N + 1 redundancy in a vSphere cluster means that the cluster has enough resources to tolerate the failure of one host without affecting the availability of the workloads. This setup provides high availability and resilience in the event of a host failure.
The following is a list of requirements from a discovery workshop for a new VMware hosting platform system design:
REQ001 - The architecture must support recoverability to the VMware Cloud Disaster Recovery (VCDR) service.
REQ002 - The architecture must support high availability (HA) and fault tolerance (FT).
REQ003 - The architecture must support reducing existing energy consumption and carbon footprint.
REQ004 - The architecture must provide support for network virtualization using distributed virtual switches.
Which requirement would be classified as a business (formerly functional) requirement?
This is a business requirement because it aligns with corporate sustainability goals, focusing on reducing environmental impact. It is a high-level goal that can drive design decisions but is not directly related to the technical function or features of the system.
