VMware 2V0-13.24 - VMware Cloud Foundation 5.2 Architect Exam

NSX Federation in VMware Cloud Foundation (VCF) 5.2 extends networking and security across multiple VCF instances (e.g., across data centers) using a leaf-spine underlay network. The architect must recommend a physical network design that supports this. Let’s evaluate:

Option A: Use a physical network that is configured for EIGRP routing adjacency

Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco-proprietary routing protocol. NSX Federation requires a Layer 3 underlay with dynamic routing (e.g., BGP, OSPF), but EIGRP isn’t a VMware-recommended standard for NSX leaf-spine designs. BGP is preferred for its scalability and interoperability in NSX-T 3.2 (used in VCF 5.2). This option is not optimal.

Option B: Layer 3 device that supports OSPF

Open Shortest Path First (OSPF) is a supported routing protocol for NSX underlays, alongside BGP. A Layer 3 device with OSPF could work in a leaf-spine topology, but VMware documentation emphasizes BGP as the primary choice for NSX Federation due to its robustness in multi-site scenarios. OSPF is valid but not the strongest recommendation for Federation-specific designs.

Option C: Ensure that the latency between VMware Cloud Foundation instances that are connected in an NSX Federation is less than 1500 ms

NSX Federation requires low latency between sites for control plane consistency (Global Manager to Local Managers). The maximum supported latency is 150 ms (not 1500 ms), per VMware specs. 1500 ms (1.5 seconds) is far too high and would disrupt Federation operations, making this incorrect.

Option D: Jumbo frames on the components of the physical network between the VMware Cloud Foundation instances

This is correct. NSX Federation relies on NSX-T overlay traffic (Geneve encapsulation) across sites, which benefits from jumbo frames (MTU ≥ 9000) to reduce fragmentation and improve performance. In a leaf-spine design, enabling jumbo frames on all physical network components (switches, routers) between VCF instances ensures efficient transport of tunneled traffic (e.g., for stretched networks). VMware strongly recommends this for NSX underlays, making it the best recommendation.

Conclusion:The architect should documentD: Jumbo frames on the components of the physical network between the VMware Cloud Foundation instances. This aligns with VCF 5.2 and NSX Federation’s leaf-spine design requirements for optimal performance and scalability.

In VMware Cloud Foundation 5.2, NSX Edge clusters provide critical networking services, such as North-South connectivity via Tier-0 Gateways, often using BGP for dynamic routing. Deploying NSX Edges via SDDC Manager integrates them into the VCF lifecycle management framework, which impacts their configuration and operational capabilities. Let’s analyze each option:

Option A: NSX Edges deployed via SDDC Manager can be updated separately in the futureIn VCF, SDDC Manager manages the lifecycle (deployment, upgrades, etc.) of NSX components, including Edge nodes. However, updates are not performed “separately” from the VCF stack; they are part of a coordinated upgrade process across the management domain. TheVCF 5.2 Administration Guidenotes that Edge updates are tied to NSX Manager and SDDC Manager workflows, contradicting the idea of independent updates. This doesn’t justify the design decision.

Option B: VPN service in NSX will be available and configurable via SDDC Manager with NSX Edges deployed using this methodWhen NSX Edges are deployed via SDDC Manager in the Management Domain, they are fully integrated into the VCF architecture. This enables advanced NSX features, such as VPN services (L2VPN, IPsec VPN), to be configured and managed through SDDC Manager or NSX Manager UIs. TheVMware Cloud Foundation 5.2 Networking Guideconfirms that deploying Edges via SDDC Manager supports North-South connectivity (e.g., via Tier-0 with BGP) and additional services like VPN, providing operational flexibility. This justifies the decision by aligning with VCF’s integrated management capabilities.

Option C: Extra Large form factor is available only when edges are deployed using SDDC ManagerNSX Edge form factors (Small, Medium, Large, Extra Large) are determined by resource requirements and deployment method, but the Extra Large form factor is available whether Edges are deployed manually via NSX Manager or through SDDC Manager in VCF. TheNSX-T Data Center Installation Guide(part of VMware docs) clarifies that form factor selection is independent of the deployment tool, making this statement inaccurate and not a justification.

Option D: This deployment method will automatically configure dynamic routingDeploying Edges via SDDC Manager automates some aspects of setup (e.g., cluster creation, basicnetworking), but dynamic routing (e.g., BGP) requires manual configuration of peers, ASNs, and route maps via NSX Manager. TheVCF 5.2 Networking Guidestates that while SDDC Manager streamlines deployment, BGP configuration remains a post-deployment task, disproving “automatic” configuration as a justification.

Conclusion:Option B is the correct justification because deploying NSX Edges via SDDC Manager ensures integration with VCF’s management plane, enabling features like VPN services alongside BGP-based North-South connectivity in the Management Domain. This aligns with the architect’s goal of leveraging VCF’s centralized management strengths.References:

The task involves adding four vSAN ESA (Express Storage Architecture) ready nodes to an existing VCF 5.2 deployment for application workloads. The current setup includes a vSAN-based Management Domain and a workload domain (A) using iSCSI storage. In VCF, workload domains are logical units with consistent storage and lifecycle management via vSphere Lifecycle Manager (vLCM). Let’s analyze each option:

Option A: Commission the four new nodes into the existing workload domain A clusterWorkload domain A uses iSCSI storage, while the new nodes are vSAN ESA ready. VCF 5.2 doesn’t support mixing principal storage types (e.g., iSCSI and vSAN) within a single cluster, as per theVCF 5.2 Architectural Guide. Commissioning vSAN nodes into an iSCSI cluster would require converting the entire cluster to vSAN, which isn’t feasible with existing workloads and violates storage consistency, making this impractical.

Option B: Create a new vLCM image workload domain with the four new nodesThis phrasing is ambiguous. vLCM manages ESXi images and baselines, but “vLCM image workload domain” isn’t a standard VCF term. It might imply a new workload domain with a custom vLCM image,but lacks clarity compared to standard options (C, D). TheVCF 5.2 Administration Guideuses “baseline” or “image-based” distinctly, so this is less precise.

Option C: Create a new vLCM baseline cluster in the existing workload domain with the four new nodesAdding a new cluster to an existing workload domain is possible in VCF, but clusters within a domain must share the same principal storage (iSCSI in workload domain A). TheVCF 5.2 Administration Guidestates that vSAN ESA requires a dedicated cluster and can’t coexist with iSCSI in the same domain configuration, rendering this option invalid.

Option D: Create a new vLCM baseline workload domain with the four new nodesA new workload domain with vSAN ESA as the principal storage aligns with VCF 5.2 design principles. vLCM baselines ensure consistent ESXi versioning and firmware for the new nodes. TheVCF 5.2 Architectural Guiderecommends separate workload domains for different storage types or workload purposes (e.g., application capacity). This leverages the vSAN ESA nodes effectively, isolates them from the iSCSI-based domain A, and supports application workloads seamlessly.

Conclusion:Option D is the best recommendation, creating a new vSAN ESA-based workload domain managed by vLCM, meeting capacity needs while adhering to VCF 5.2 storage and domain consistency rules.References:

The requirement is to reduce network latency between two application virtual machines (VMs) in a VMware Cloud Foundation (VCF) 5.2 SDDC environment. Network latency is influenced by the physical distance and network hops between VMs. In a vSphere environment (core to VCF), VMs on the same ESXi host communicate via the host’s virtual switch (vSwitch or vDS), avoiding physical network traversal, which minimizes latency. Let’s evaluate each option:

Option A: Configure a Storage DRS rule to keep the application virtual machines on the same datastoreStorage DRS manages datastore usage and VM placement based on storage I/O and capacity, not network latency. ThevSphere Resource Management Guidenotes that Storage DRS rules (e.g., VMaffinity) affect storage location, not host placement. Two VMs on the same datastore could still reside on different hosts, requiring network communication over physical links (e.g., 10GbE), which doesn’t inherently reduce latency.

Option B: Configure a DRS rule to keep the application virtual machines on the same ESXi hostDRS (Distributed Resource Scheduler) controls VM placement across hosts for load balancing and can enforce affinity rules. A “keep together” affinity rule ensures the two VMs run on the same ESXi host, where communication occurs via the host’s internal vSwitch, bypassing physical network latency (typically <1µs vs. milliseconds over a LAN). TheVCF 5.2 Architectural GuideandvSphere Resource Management Guiderecommend this for latency-sensitive applications, directly meeting the requirement.

Option C: Configure a DRS rule to separate the application virtual machines to different ESXi hostsA DRS anti-affinity rule forces VMs onto different hosts, increasing network latency as traffic must traverse the physical network (e.g., switches, routers). This contradicts the goal of reducing latency, making it unsuitable.

Option D: Configure a Storage DRS rule to keep the application virtual machines on different datastoresA Storage DRS anti-affinity rule separates VMs across datastores, but this affects storage placement, not host location. VMs on different datastores could still be on different hosts, increasing network latency over physical links. This doesn’t address the requirement, per thevSphere Resource Management Guide.

Conclusion:Option B is the correct design decision. A DRS affinity rule ensures the VMs share the same host, minimizing network latency by leveraging intra-host communication, aligning with VCF 5.2 best practices for latency-sensitive workloads.References:

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.

In VMware Cloud Foundation (VCF) 5.2, design qualities (non-functional requirements) categorizehowthe system operates. The network team’s requirements focus on redundancy and routing diversity, which the architect must classify. Let’s evaluate:

Option A: Availability

This is correct. Availability ensures the solution remains operational and accessible. “N+N redundancy” (e.g., dual active components where N failures are tolerated by N spares) for physical networking components eliminates single points of failure, ensuring continuous network uptime. “Diversely routed inter-datacenter links” prevents outages from a single path failure, enhancing availability across sites. In VCF, these align with high-availability network design (e.g., NSX Edge uplink redundancy), makingavailabilitythe proper classification.

Option B: Performance

Performance addresses speed, throughput, or latency (e.g., “10 Gbps links”). Redundancy and diverse routing might indirectly support performance by avoiding bottlenecks, but the primary intent is uptime, not speed. This doesn’t fit the stated requirements’ focus.

Option C: Recoverability

Recoverability focuses on restoring service after a failure (e.g., backups, failover time). N+N redundancy and diverse routingpreventdowntime rather than recover from it. While related, the requirements emphasize proactive uptime (availability) over post-failure recovery, making this incorrect.

Option D: Manageability

Manageability concerns ease of administration (e.g., monitoring, configuration). Redundancy and routing diversity are infrastructure design choices, not management processes. This quality doesn’t apply.

Conclusion:The architect should classify the requirement asAvailability (A). It ensures the VCF solution’s network remains operational, aligning with VCF 5.2’s focus on resilient design.
