2V0-13.25 Online Practice Questions

Explanation:
Comprehensive and Detailed Explanation (Based on VMware Cloud Foundation 9.0.3 and 9.0.1 Guides):
The VMware Cloud Foundation 9.0.3 Disaster Recovery Planning Guide emphasizes that testing and validation of DR plans must occur regularly and whenever infrastructure changes are made.
It states:
“You can perform test runs periodically to ensure the existing disaster recovery plan works with underlying infrastructure and the configured RPO limit. VMware Live Recovery recommends users perform planned migration at regular intervals to validate the integrity of the existing DR plan.”
Additionally, the VCF 9.0.1 Design Blueprints specify that a well-defined process for reviewing and updating DR documentation between changes ensures continuity and compliance with defined Service Level Objectives (SLOs).
Thus, the correct mitigation action is to establish a structured change management process that includes DR plan updates and monthly end-to-end validation tests. Simply limiting change frequency (option C) or setting replication intervals (option D) does not ensure DR plan integrity.

Explanation:
Upgrading a vSphere + vSAN environment to a full VMware Cloud Foundation deployment requires introducing the components that make up the integrated software-defined data center (SDDC):
A. NSX C Provides network virtualization, overlay segments, distributed firewalling, and routing required in VCF.
B. SDDC Manager C The core management and lifecycle automation tool of VCF, responsible for bring-up, patching, and upgrades.
E. vSphere Supervisor C Required to enable VMware Tanzu Kubernetes Grid (TKG) and modern application deployment in VCF environments.
Why not the others?
C. VCF Identity Broker C Provides federated authentication but is not mandatory for initial upgrade.
It is optional depending on identity requirements.
D. VCF Operations C This is VMware Aria Operations (for monitoring/analytics). While strongly recommended, it is not required to upgrade from vSphere/vSAN to VCF.

Explanation:
The VCF Identity Broker (VIDB) enables integration with enterprise identity systems and supports
MFA.
To reduce operational overhead:
Deploy VIDB once in the first VCF instance at DC01.
Point all additional VCF instances in the same private cloud to this VIDB.
This avoids deploying and managing multiple VIDB instances, reducing lifecycle overhead while still enabling 2FA.
Options A/B introduce unnecessary duplication. Option C centralizes in DC02, but requirement specifies DC01 is primary.

Explanation:
The Conceptual Model identifies high-level requirements, constraints, assumptions, and risks. The Logical Design translates those into how solution components (clusters, networks, storage, security zones, etc.) are structured to meet dependencies and requirements.
Physical Design comes after Logical Design and defines specific hardware, IP addresses, VLANs, etc.
High Availability Design is a subset of the logical/physical design focusing only on resiliency.
Configuration Guide is implementation-level documentation, not design.
Thus, the Logical Design defines how the infrastructure’s capabilities are arranged to satisfy conceptual dependencies.

Explanation:
The VMware Cloud Foundation 9.0.2 Design Guide specifies that in a Highly Available (HA) VCF Automation deployment, three appliances are deployed to ensure redundancy and meet a minimum availability SLA of 99.9%.
To maintain continuous performance during host maintenance or hardware failure, VMware recommends:
“Each appliance instance should be placed on a separate ESXi host using a VM-host anti-affinity rule to eliminate single points of failure.”
Furthermore, to achieve external traffic distribution and redundancy, the guide states:
“In HA mode, an external load balancer is required to distribute requests across the cluster nodes and provide failover when a node or host becomes unavailable.”
The native Kubernetes load balancer cannot manage cross-node traffic distribution in an HA VCF Automation setup. Therefore, the architect must configure an external load balancer and define anti-affinity rules to ensure appliance distribution across hosts, achieving both the SLA and fault tolerance requirements.
