VMware Certification 3V0-21.23 Book

Six 10TB VMFS datastores will be configured on each site for all production workloads.

This choice is based on the need to distribute production workloads across multiple datastores while ensuring that each datastore is large enough to accommodate the space required by the workloads. Given the average sizes of the virtual machines and the growth and snapshot overhead, six 10TB VMFSdatastores would be appropriate for production workloads, ensuring scalability while minimizing the number of LUNs.

Each 10TB LUN will be configured as a VMFS datastore.

VMFS (Virtual Machine File System) is the standard choice for vSphere environments when using Fibre Channel LUNs. It provides the necessary features, such as concurrency and high-performance access, for production workloads. This option is appropriate given that the storage array uses Fibre Channel for connection and VMFS is the standard file system for such configurations.

Two 10TB VMFS datastores will be configured on each site for all DMZ workloads.

The DMZ workloads are smaller in number and storage requirements compared to the production workloads, so configuring two 10TB VMFS datastores for DMZ workloads will provide enough capacity while maintaining logical isolation. This approach also minimizes the number of LUNs required to meet the storage growth needs.

The solution will configure the six (6) available network connections into load balanced pairs.

Configuring the six network connections into load-balanced pairs ensures that network traffic is distributed efficiently across the available physical NICs, providing redundancy and preventing any single network adapter from becoming a bottleneck. This aligns with the requirement to separate and balance traffic types, ensuring that no single network adapter is overloaded.

The solution will deploy a vSphere distributed switch with three (3) uplink port groups.

Using a vSphere Distributed Switch with three uplink port groups provides a clean separation of traffic types (management, replication, vMotion, and workload traffic). The distributed switch allows for better scalability, visibility, and management of network traffic in a multi-NIC setup, meeting the need to segregate network traffic and ensure redundancy at the switch level.

The solution will configure the Route Based on Physical NIC Load load balancing method.

The Route Based on Physical NIC Load load balancing method distributes traffic based on the current load of each physical NIC, ensuring that network traffic is balanced efficiently across all available NICs. This helps maintain optimal performance and ensures that one NIC is not overwhelmed by traffic from different types of network operations.

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.
