VMware 2V0-13.24 Practice Test Questions Answers

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 architect’s design decisions for the VMware Cloud Foundation (VCF) solution must align with the hardware specifications, the latency-sensitive nature of the applications, and VMware best practices for performance optimization. To justify the decisions limiting VMs to 10 vCPUs and 256 GB RAM, we need to analyze the ESXi host configuration and the implications of NUMA (Non-Uniform Memory Access) architecture, which is critical for latency-sensitive workloads.

ESXi Host Configuration:

CPU:2 sockets, each with 10 cores (20 cores total, or 40 vCPUs with hyper-threading, assuming it’s enabled).

RAM:512 GB total, divided evenly between sockets (256 GB per socket).

Each socket represents a NUMA node, with its own local memory (256 GB) and 10 cores. NUMA nodes are critical because accessing local memory is faster than accessing remote memory across nodes, which introduces latency.

Design Decisions:

Maximum 10 vCPUs per VM:Matches the number of physical cores in one socket (NUMA node).

Maximum 256 GB RAM per VM:Matches the memory capacity of one socket (NUMA node).

Latency-sensitive applications:These workloads (e.g., research applications) require minimal latency, making NUMA optimization a priority.

NUMA Overview (VMware Context):In vSphere (a core component of VCF), each physical CPU socket and its associated memory form a NUMA node. When a VM’s vCPUs and memory fit within a single NUMA node, all memory access is local, reducing latency. If a VM exceeds a NUMA node’s resources (e.g., more vCPUs or memory than one socket provides), it spans multiple nodes, requiring remote memory access, which increases latency—a concern for latency-sensitive applications. VMware’s vSphere NUMA scheduler optimizes VM placement, but the architect can enforce performance by sizing VMs appropriately.

Option Analysis:

A. The maximum resource configuration will ensure efficient use of RAM by sharing memory pages between virtual machines:This refers to Transparent Page Sharing (TPS), a vSphere feature that allows VMs to share identical memory pages, reducing RAM usage. While TPS improves efficiency, it is not directly tied to the decision to cap VMs at 10 vCPUs and 256 GB RAM. Moreover, TPS has minimal impact on latency-sensitive workloads, as it’s a memory-saving mechanism, not a performance optimization for latency. The VMware Cloud Foundation Design Guide and vSphere documentation note that TPS is disabled by default in newer versions (post-vSphere 6.7) due to security concerns, unless explicitly enabled. This justification does not align with the latency focus or the specific resource limits, making it incorrect.

B. The maximum resource configuration will ensure the virtual machines will cross NUMA node boundaries:If VMs were designed to cross NUMA node boundaries (e.g., more than 10 vCPUs or 256 GB RAM), their vCPUs and memory would span both sockets. For example, a VM with 12 vCPUs would use cores from both sockets, and a VM with 300 GB RAM would require memory from both NUMA nodes. This introduces remote memory access, increasing latency due to inter-socket communication over the CPU interconnect (e.g., Intel QPI or AMD Infinity Fabric). For latency-sensitive applications, crossing NUMA boundaries is undesirable, as noted in the VMware vSphere Resource Management Guide. This option contradicts the goal and is incorrect.

C. The maximum resource configuration will ensure the virtual machines will adhere to a single NUMA node boundary:By limiting VMs to 10 vCPUs and 256 GB RAM, the architect ensures each VM fits within one NUMA node (10 cores and 256 GB per socket). This means all vCPUs and memory for a VM are allocated from the same socket, ensuring local memory access and minimizing latency. This is a critical optimization for latency-sensitive workloads, as remote memory access is avoided. The vSphere NUMA scheduler will place each VM on a single node, and since the VM’s resource demands do not exceed the node’s capacity, no NUMA spanning occurs. The VMware Cloud Foundation 5.2 Design Guide and vSphere best practices recommend sizing VMs to fit within a NUMA node for performance-critical applications, making this the correct justification.

D. The maximum resource configuration will ensure each virtual machine will exclusively consume a whole CPU socket:While 10 vCPUs and 256 GB RAM match the resources of one socket, this option implies exclusive consumption, meaning no other VM could use that socket. In vSphere, multiple VMs can share a NUMA node as long as resources are available (e.g., two VMs with 5 vCPUs and 128 GB RAM each could coexist on one socket). The architect’s decision does not mandate exclusivity but rather ensures VMs fit within a node’s boundaries. Exclusivity would limit scalability (e.g., only two VMs per host), which isn’t implied by the design or required by the scenario. This option overstates the intent and is incorrect.

Conclusion:The architect should record thatthe maximum resource configuration will ensure the virtual machines will adhere to a single NUMA node boundary (C). This justification aligns with the hardware specs, optimizes for latency-sensitive workloads by avoiding remote memory access, and leverages VMware’s NUMA-aware scheduling for performance.

In VMware Cloud Foundation (VCF) 5.2, Cloud Automation (e.g., Aria Automation) and Operations (e.g., Aria Operations) products rely on identity management for authentication. The customer’s requirements—corporate directory authentication, Active/Standby across two sites, disaster recovery (DR), network zoning, slow firewall processes, and a 3-month deployment timeline—shape the design decisions. The architect must ensure authentication works efficiently across sites while meeting the timeline and DR needs. Let’s evaluate:

Key Constraints and Context:

Authentication: All users/administrators use the corporate directory (e.g., Active Directory in the corporate zone).

Deployment: Active/Standby across two sites, with management apps in a separate tooling zone behind firewalls.

DR: Management apps must recover to the standby site.

Firewall Delays: 8-week minimum per rule, but deployment must occur within 12 weeks (3 months).

Identity Broker: In VCF, VMware Workspace ONE Access (or similar) acts as an identity broker, bridging VCF components with external directories (e.g., AD via LDAP/S).

Evaluation of Options:

Option A: The Cloud Automation and Operations products will be reconfigured to integrate with the Identity Broker solution instance at the standby site in case of a Disaster Recovery incident

This implies a single Identity Broker at the primary site, with reconfiguration to a standby instance post-DR. Reconfiguring products (e.g., updating SSO endpoints) during DR adds complexity and downtime, contradicting the Active/Standby goal of seamless failover. It’s feasible but not optimal given the need for continuous operation and the 3-month timeline.

Option B: The Identity Broker solution will be deployed at both the primary and standby site

This is correct. Deploying Workspace ONE Access (or equivalent) at both sites supports Active/Standby by ensuring authentication availability at the primary site and immediate usability at the standby site post-DR. It aligns with VCF’s multi-site HA capabilities and avoids reconfiguration delays, addressing the DR requirement efficiently within the timeline.

Option C: The Identity Broker solution will be connected with the corporate directory service for user authentication

This is correct. The requirement states all users/administrators authenticate via the corporate directory (in the corporate zone). An Identity Broker (e.g., Workspace ONE Access) connects to AD via LDAP/S, acting as a proxy between the management tooling zone and corporate zone. This satisfies the authentication need and simplifies firewall rules (one broker-to-AD connection vs. multiple app connections), critical given the 8-week delay.

Option D: The Identity Broker solution will be deployed at the primary site and failed over to the standby site in case of a disaster

This suggests a single Identity Broker with DR failover. While possible (e.g., via vSphere Replication), it risks authentication downtime during failover, conflicting with Active/Standby continuity. The 8-week firewall rule delay for the standby site’s broker connection post-DR also jeopardizes the 3-month timeline and DR readiness, making this less viable than dual-site deployment (B).

Option E: The Cloud Automation and Operations products will be integrated with a single instance of an Identity Broker solution at the primary site

This is correct. Integrating Aria products with one Identity Broker instance at the primary site during initial deployment simplifies setup and meets the 3-month timeline. It leverages the broker deployed at the primary site (part of B) for authentication, minimizing firewall rules (one broker vs. multiple apps). Pairing this with a standby instance (B) ensures DR readiness without immediate complexity.

Option F: The Cloud Automation and Operations products will be integrated directly with the corporate directory service

This is incorrect. Direct integration requires each product (e.g., Aria Automation, Operations) to connect to AD across the firewall, necessitating multiple rule requests. With an 8-week minimum per rule and several products, this exceeds the 3-month timeline. It also complicates DR, as each app would need re-pointing to a standby AD, violating efficiency and zoning policies.

Conclusion:

The three design decisions are:

B: Identity Broker at both sites ensures Active/Standby and DR readiness.

C: Connecting the broker to the corporate directory fulfills the authentication requirement and simplifies firewall rules.

E: Integrating products with a primary-site broker meets the 3-month deployment goal while leveraging B and C for DR.This trio balances timeline, security, and DR needs in VCF 5.2.
