Free Practice Questions for EMC D-VXB-DY-A-24 Exam

Review ACI Fabric Concepts: Within the ACI fabric, logical constructs are used to organize and manage network resources1.

Identify the EPG: An Endpoint Group (EPG) is a collection of similar endpoints that represent an application tier or set of services within the ACI fabric1.

Understand the Role of EPGs: EPGs group endpoints with identical networking policy requirements, allowing for the application of policies that regulate how such groups can interact with each other1.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with Cisco’s guidelines on ACI fabric, which define EPGs as collections of similar endpoints representing an application tier or set of services1.

Review Cisco ACI Components: Cisco Application Centric Infrastructure (ACI) is a comprehensive networking solution for data centers, which includes specific components designed to work within its architecture1.

Identify Non-ACI Component: Among the options provided, NSX Manager is not part of the Cisco ACI solution.NSX Manager is a component of VMware’s NSX network virtualization platform, which is separate from Cisco’s ACI1.

Understand ACI Architecture: The Cisco ACI architecture is designed around the Cisco Application Policy Infrastructure Controller (APIC) and the Nexus 9000 series switches, which work together to provide a policy-driven solution that automates network provisioning and control1.

Recognize ACI Specific Entities: The ACI Policy Model and Nexus 9000 Series Switches are integral parts of the Cisco ACI solution, supporting its intent-based networking framework1.

Based on CPSD (Converged Platform & Solutions Division) guidelines for VxBlock 1000, up to 6 UCS chassis can be installed in a single rack. This configuration maximizes the use of available space while maintaining proper airflow and cooling.

The Distributed Logical Router (DLR) is the NSX component that abstracts the physical network and provides access-level switching in the hypervisor. The DLR enables routing between different virtual networks and operates at the hypervisor level, providing high-performance distributed routing capabilities.

In the Dell EMC RCM (Release Certification Matrix) Workbook upgrade plan, the sequence of upgrading VxBlock components is designed to ensure system stability and minimize disruptions. Here’s the detailed reasoning for the correct sequence:

VxBlock Central:

Explanation: VxBlock Central is the management and orchestration layer of the VxBlock system. Upgrading this first ensures that the management tools are compatible with the new versions of the other components and can properly coordinate and monitor the upgrade process.

When creating an NSX logical switch, a required step is to create a new name for the logical switch. Naming the logical switch is necessary to identify and manage it within the NSX environment.

Understand Isilon Storage: Isilon storage systems are designed to provide a scalable solution for file-based data applications and workflows1.

Identify the File System Architecture: The Isilon storage uses a single volume, single namespace, single file system architecture known as OneFS.This architecture is inherently distributed, allowing for easy scaling from tens of terabytes to tens of petabytes1.

Recognize the Benefits of a Distributed Architecture: The distributed nature of the OneFS file system architecture allows Isilon storage systems to deliver increased performance and scalability, which is essential for handling large volumes of file-based data1.

Map to VxBlock 1000: In the context of the VxBlock 1000, the Isilon storage with its distributed file system architecture integrates with the converged infrastructure to support high-performance workloads and efficient data management2.

When planning a compute expansion in an existing VxBlock 1000 system with servers repurposed from another VxBlock system, the required licensing includes VMware vSphere ESXi and Cisco 1000v licenses. These licenses ensure that the new compute resources are properly integrated and managed within the existing VxBlock environment.

Cisco licensing guides for UCS and network components.

Review the RCM Upgrade Process: The RCM (Release Certification Matrix) upgrade process involves a series of steps to ensure that the VxBlock system is updated according to Dell EMC’s standards1.

Identify the Role of the RCM Lead: The RCM Lead is typically responsible for overseeing the RCM upgrade process, which includes raising the Internal Assessment (IA) to ensure that all components are compliant with the latest RCM standards1.

Understand the Importance of IA: The Internal Assessment is a critical part of the RCM upgrade process.It helps identify any potential issues that might affect the upgrade and ensures that the system is ready for the new RCM1.

Acknowledge the Responsibilities: While the Project Manager, Implementation Specialist, and District Manager may have roles in the RCM upgrade process, it is the RCM Lead who is specifically responsible for raising the IA as part of their duties1.

The LCS (Logical Configuration Survey) document contains all software baseline information post-RCM upgrade. It details the current configuration of the system, including software versions and settings, which are critical for maintaining system integrity and for future reference during support and maintenance activities.
