VMware 2V0-13.24 Exam With Confidence Using Practice Dumps

This scenario involves a VCF multi-AZ design where AZs must operate independently (no shared dependencies) and achieve a 99.9% availability SLA (allowing ~8.76 hours of downtime annually). The design decisions must ensure resilience, fault isolation, and recovery capabilities across AZs.

Requirement Analysis:

Independent AZ operation:Each AZ must function standalone, with no single point of failure or dependency across AZs.

99.9% availability:The design must minimize downtime through redundancy, replication, and recovery mechanisms.

Option Analysis:

A. Configure array-based replication between the selected AZ(s) for the management domain:Array-based replication (e.g., vSphere Replication or SAN replication) for the management domain (vCenter, NSX Manager, SDDC Manager) ensures that critical management VMs are duplicated across AZs. If one AZ fails, the other can take over with minimal downtime, supporting independent operation and high availability. The VCF 5.2 Design Guide recommends replication for multi-AZ deployments to meet SLAs, as it provides a recovery point objective (RPO) near zero. This option enhances availability and is correct.

B. Make sure all configuration backups are replicated between the selected AZ(s):Replicating configuration backups (e.g., SDDC Manager backups, NSX configurations) ensures that each AZ has access to recovery data. If an AZ’s management components fail, the other AZ can restore operations independently using its local backup copy. This supports the independence requirement and reduces downtime (contributing to 99.9% SLA) by enabling quick recovery. The VCF Administration Guide emphasizes backup replication for multi-AZ resilience, making this option correct.

C. Make sure the recovery VLAN for the infrastructure management components has access to both AZ(s):A recovery VLAN spanning both AZs implies a shared network dependency. If this VLAN fails (e.g., due to a network outage), both AZs could be impacted, violating the independence requirement. Multi-AZ designs in VCF favor isolated networks per AZ to avoid cross-AZ single points of failure. The VCF Design Guide advises against shared VLANs for critical components in independent AZ setups. This option undermines the requirements and is incorrect.

D. Choose two distant AZ(s) and consider each AZ the DR for the other:Distant AZs (e.g., separate data centers) with mutual DR (disaster recovery) roles enhance geographic fault tolerance. However, “operate independently” in VCF typically means each AZ can run workloads standalone, not that one is a passive DR site. Distant AZs introduce latency, complicating synchronous replication needed for 99.9% availability, and may rely on shared management, conflicting with independence. The VCF Multi-AZ Guide focuses on active-active AZs, not DR-centric designs, making this less suitable.

E. Choose two close proximity AZ(s) and configure a stretched management workload domain:A stretched management domain (e.g., using vSAN stretched cluster) spans AZs with synchronous replication, ensuring high availability. However, this creates a dependency: both AZs share the same vCenter and management stack, so a failure (e.g., vCenter outage) could affect both, violating independence. The VCF 5.2 Design Guide notes stretched clusters are for single logical domains, not independent AZs. This option contradicts the requirement and is incorrect.

F. Configure a non-routable separate recovery VLAN for the infrastructure management components within each AZ:A non-routable, AZ-specific recovery VLAN isolates management recovery traffic (e.g., for vMotion, backups) within each AZ. This ensures that each AZ’s management components operate independently, with no cross-AZ network reliance. If one AZ’s network fails, the other remains unaffected, supporting the SLA through fault isolation. The VCF Multi-AZ Design Guide recommends separate, isolated networks per AZ for resilience, making this option correct.

Conclusion:The three design decisions areConfigure array-based replication between the selected AZ(s) for the management domain (A),Make sure all configuration backups are replicated between the selected AZ(s) (B), andConfigure a non-routable separate recovery VLAN for the infrastructure management components within each AZ (F). These ensure independent operation and meet the 99.9% SLA through replication and isolation.

VMware HCX (Hybrid Cloud Extension) is a key workload migration tool in VMware Cloud Foundation (VCF) 5.2, enabling seamless movement of VMs between on-premises environments and VCF instances (or between VCF instances). To plan an HCX-based migration, the architect must ensure prerequisites are met for deployment, connectivity, and operation. Let’s evaluate each option:

Option A: Extended IP spaces for all moving workloadsThis is incorrect. HCX supports migrations with or without extending IP spaces. Features like HCX vMotion and Bulk Migration allow VMs to retain their IP addresses (Layer 2 extension via Network Extension), while HCX Mobility Optimized Networking (MON) can adapt IPs if needed. Extended IP space is a design choice, not a prerequisite, making this option unnecessary for completing the objective.

Option B: DRS enabled within the VCF instanceThis is incorrect. VMware Distributed Resource Scheduler (DRS) optimizes VM placement and load balancing within a cluster but is not required for HCX migrations. HCX operates independently of DRS, handling VM mobility across environments (e.g., from a source vSphere to a VCF destination). While DRS might enhance resource management post-migration, it’s not a prerequisite for HCX functionality.

Option C: Service accounts for the applicable appliancesThis is correct. HCX requires service accounts with appropriate permissions to interact with source anddestination environments (e.g., vCenter Server, NSX). In VCF 5.2, HCX appliances (e.g., HCX Manager, Interconnect, WAN Optimizer) need credentials to authenticate and perform operations like VM discovery, migration, and network extension. The architect must ensure these accounts are configured with sufficient privileges (e.g., read/write access in vCenter), making this a critical prerequisite.

Option D: NSX Federation implemented between the VCF instancesThis is incorrect. NSX Federation is a multi-site networking construct for unified policy management across NSX deployments, but it’s not required for HCX migrations. HCX leverages its own Network Extension service to stretch Layer 2 networks between sites, independent of NSX Federation. While NSX is part of VCF, Federation is an advanced feature unrelated to HCX’s core migration capabilities.

Option E: Active Directory configured as an authentication sourceThis is correct. In VCF 5.2, HCX integrates with the VCF identity management framework, which typically uses Active Directory (AD) via vSphere SSO for authentication. Configuring AD as an authentication source ensures that HCX administrators can log in using centralized credentials, aligning with VCF’s security model. This is a prerequisite for managing HCX appliances and executing migrations securely.

Conclusion:The two prerequisites required for HCX migration in VCF 5.2 areservice accounts for the applicable appliances(Option C) to enable HCX operations andActive Directory configured as an authentication source(Option E) for secure access management. These align with HCX deployment and integration requirements in the VCF ecosystem.
