VMware Professional 2V0-13.24 Exam Dumps

In VMware Cloud Foundation (VCF) 5.2, requirements are classified asfunctional(what the system must do) ornon-functional(how the system performs or operates). Functional requirements describe specific capabilities or behaviors, while non-functional requirements address qualities like performance, security, or constraints. Let’s classify each:

Option A: REQ01 - The application server must handle at least 30,000 transactions per second

This is correct. This is afunctional requirementbecause it specifies what the application server (a component of the solution) must do—process a defined transaction volume. It’s a capability the system must deliver, directly tied to workload performance within the VCF environment.

Option B: REQ02 - The design must meet ISO 27001 information security standards

This is anon-functional requirement. ISO 27001 addresses security qualities (e.g., confidentiality, integrity), defininghowthe system should operate securely, not what it does. It’s a compliance and operational constraint, not a functional capability.

Option C: REQ03 - The storage network should maintain a minimum latency of 12 milliseconds before path failover

This is anon-functional requirement. It specifies a performance threshold (latency) and reliability behavior (failover), describinghowthe storage network should perform, not a specific function it must provide.

Option D: REQ04 - The staging environment should utilize a secondary third-party data center

This is correct. This is afunctional requirementbecause it defines what the solution must include—a staging environment located in a specific secondary data center. It’s a capability or structural requirement of the VCF deployment, dictating a functional aspect of the system.

Option E: REQ05 - Planned maintenance must be performed outside the hours of 8 AM to 8 PM GMT

This is anon-functional requirement. It’s an operational constraint onwhenmaintenance occurs, affecting availability and manageability, not a specific function the system must perform.

Conclusion:The two functional requirements areREQ01 (A)andREQ04 (D). They define what the VCF solution must do (handle transactions, include a staging environment), aligning with VMware’s design methodology for functional specifications.

The scenario involves a VCF consolidated architecture with seven ESXi hosts in a single cluster, likely using vSAN as the default storage (standard in VCF consolidated deployments unless specified otherwise). The goal is to minimize storage I/O disruption for an application’s two VMs during business hours while maintaining availability, all within budget and hardware constraints.

Requirement Analysis:

Minimal disruption to storage I/O:Storage I/O disruptions typically occur during vSAN resyncs, host maintenance, or resource contention.

No reduction in availability:Solutions must not compromise the cluster’s ability to keep VMs running and accessible.

Budget/hardware constraints:Options requiring new hardware purchases are infeasible.

Option Analysis:

A. Apply 100% CPU and memory reservations on these virtual machines:Setting 100% CPU and memory reservations ensures these VMs get their full allocated resources, preventing contention with other VMs. However, this primarily addresses compute resource contention, not storage I/O disruptions. Storage I/O is managed by vSAN (or another shared storage), and reservations do not directly influence disk latency, resync operations, or I/O performance during maintenance. The VMware Cloud Foundation 5.2 Administration Guide notes that reservations are for CPU/memory QoS, not storage I/O stability. This option does not effectively mitigate the risk and is incorrect.

B. Implement FTT=1 Mirror for this application virtual machine:FTT (Failures to Tolerate) = 1 with a mirroring policy (RAID-1) in vSAN ensures that each VM’s data is replicated across at least two hosts, providing fault tolerance. During business hours, if a host fails or enters maintenance, vSAN maintains data availability without immediate resync (since data is already mirrored), minimizing I/O disruption. Without this policy (e.g., FTT=0), a host failure could force a rebuild, impacting I/O. The VCF Design Guide recommends FTT=1 for critical applications to balance availability and performance. This option leverages existing hardware, maintains availability, and reduces I/O disruption risk, making it correct.

C. Replace the vSAN shared storage exclusively with an All-Flash Fibre Channel shared storage solution:Switching to All-Flash Fibre Channel could improve I/O performance and potentially reduce disruption (e.g., faster rebuilds), but it requires purchasing new hardware (Fibre Channel HBAs, switches, and storage arrays), which violates the budget constraint. Additionally, transitioning from vSAN (integral to VCF) to external storage in a consolidated architecture is unsupported without significant redesign, as per the VCF 5.2 Release Notes. This option is impractical and incorrect.

D. Perform all host maintenance operations outside of business hours:Host maintenance (e.g., patching, upgrades) in vSAN clusters triggers data resyncs as VMs and data are evacuated, potentially disrupting storage I/O during business hours. Scheduling maintenance outside business hours avoids this, ensuring I/O stability when the application is in use. This leverages DRS and vMotion (standard in VCF) to move VMs without downtime, maintaining availability. The VCF Administration Guide recommends off-peak maintenance to minimize impact, making this a cost-effective, availability-preserving solution. This option is correct.

E. Enable fully automatic Distributed Resource Scheduling (DRS) policies on the cluster:Fully automated DRS balances VM placement and migrates VMs to optimize resource usage. While this improves compute efficiency and can reduce contention, it does not directly mitigate storage I/O disruptions. DRS migrations can even temporarily increase I/O (e.g., during vMotion), and vSAN resyncs (triggered by maintenance or failures) are unaffected by DRS. The vSphere Resource Management Guide confirms DRS focuses on CPU/memory, not storage I/O. This option is not the most effective here and is incorrect.

Conclusion:The two most effective options areImplement FTT=1 Mirror for this application virtual machine (B)andPerform all host maintenance operations outside of business hours (D). These ensure storage redundancy and schedule disruptive operations outside critical times, maintaining availability without additional hardware.
