2V0-11.25

The VMware 2V0-11.25 exam, covering VMware vSAN 8, focuses on the design and deployment of VMware's hyper-converged infrastructure (HCI) solution. The main points revolve around these core areas:

• vSAN Architecture and Components: A deep understanding of vSAN's architecture, including its various components (disks, hosts, clusters, witness hosts, etc.), their interactions, and their roles in overall system functionality. This includes knowledge of different storage policies and their impact.

• Storage Policy-Based Management (SPBM): Mastering the creation and management of storage policies based on various Service Levels Objectives (SLOs) to meet application requirements for performance (IOPS, latency) and capacity. Understanding how these policies are applied and enforced.

• Deployment and Configuration: Practical skills in deploying and configuring vSAN clusters, including considerations for networking, storage capacity planning, and disk selection (SSD vs. HDD). This involves understanding different deployment models and best practices.

• Capacity Management and Monitoring: The ability to monitor vSAN performance, capacity utilization, and health. Identifying potential bottlenecks and proactively addressing capacity planning issues. This includes understanding vSAN's reporting and alerting features.

• Troubleshooting and Maintenance: The skills to diagnose and resolve common vSAN issues, including performance problems, capacity constraints, and hardware failures. Knowledge of proactive maintenance tasks and recovery procedures.

• High Availability and Disaster Recovery: Understanding how vSAN contributes to high availability and disaster recovery solutions through features like stretched clusters, witness hosts, and replication.

• Security: Understanding security considerations within a vSAN environment, including data encryption and access control. Knowing how to configure vSAN for secure operation.

• vSAN Hybrid and All-Flash Configurations: Knowledge of the differences and best practices for deploying vSAN in hybrid (SSD and HDD) and all-flash configurations. This includes understanding the trade-offs between performance and cost.

In short, the exam assesses a candidate's ability to design, deploy, manage, and troubleshoot a vSAN 8 environment effectively, meeting specific performance and availability requirements. It moves beyond basic configuration and emphasizes practical, real-world application of the technology.
