Free EMC D-VXB-DY-A-24 Practice Exam with Questions & Answers

The label on the cable indicates two parts: “M91A-01:01” and “U61A-01:09”. The first part of the label “M91A” refers to a specific type of equipment as per the exhibit. According to the exhibit, “M9” corresponds to “MDS 9xxx”, which is a Cisco Multilayer Director Switch. The second part of the label, “U61A”, does not directly match any category in the provided list; however, it seems to be an internal reference that could be related to user-specific configurations or locations.

Since we are looking for the target equipment type and not where it was mistakenly connected, we focus on the first part of the cable label. The numbers following “M91A” indicate slot and port information. Therefore, based on this labeling system and referring to the exhibit provided, which lists various EMC and Cisco equipment types along with their corresponding codes (like AP for APIC Appliance or CN for Cust. Network), we can deduce that “M91A” stands for “MDS 9xxx”. The subsequent numbers “-01:01” suggest Slot 1, Port 1.

Review the VxBlock and Nexus Documentation: The VxBlock 1000 system documentation and the Nexus 93180YC switch documentation should be reviewed to understand the supported routing protocols1.

Consider the Juniper Switch Capabilities: Since the customer is using a Juniper switch as the core switch, it’s important to consider the routing protocols supported by Juniper switches.Juniper switches support a variety of routing protocols, including OSPF2.

Evaluate Routing Protocol Options: EIGRP is typically Cisco proprietary and not supported on Juniper devices. IGMP is not a routing protocol but a multicast management protocol.IGRP is an older Cisco proprietary routing protocol and is less commonly used today2.

Recommend OSPF: OSPF (Open Shortest Path First) is a widely supported, robust, and scalable dynamic routing protocol that is suitable for diverse environments, including mixed vendor setups like Cisco’s Nexus and Juniper switches2.

Validate with Best Practices: Best practices and recommendations from both Cisco and Juniper suggest using OSPF for dynamic routing between devices from different vendors2.

Identify the Issue: Heavy network utilization during video streaming indicates that multicast traffic is not being efficiently managed1.

Understand Multicast Traffic: Multicast applications use a single stream of data to deliver content to multiple recipients, which can cause network congestion if not handled properly1.

Recognize IGMP’s Role: Internet Group Management Protocol (IGMP) is used to manage multicast group memberships and is essential for optimizing multicast traffic on a network1.

Implement IGMP: Enabling IGMP allows the network to efficiently distribute multicast traffic only to hosts that have explicitly requested it, reducing unnecessary network load1.

Review PowerMax 8000 Specifications: The PowerMax 8000 is designed to support a dispersed configuration, allowing for flexibility in the physical placement of its components1.

Identify Maximum Dispersion: The maximum allowed dispersion between bricks in a PowerMax 8000 system is up to 25 meters1.

Understand Dispersion Considerations: This dispersion allows for the separation of individual or contiguous groups of system bays, providing options for physical layout within a data center1.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with this specification, ensuring that the system meets both performance and physical space requirements1.

Understand SDN: Software Defined Networking (SDN) is a transformative approach to network management that allows for centralized control and dynamic resource management1.

Identify Key Benefits: One of the primary benefits of SDN is the improvement in network management efficiency.By centralizing control, SDN simplifies the management of network resources and services1.

Recognize Efficiency Gains: With SDN, network administrators can quickly respond to changing network conditions and demands without the need for manual configuration of individual network devices1.

Reference Industry Insights: The improvement in network management efficiency is a widely recognized benefit of SDN, as it enables more agile and responsive network operations1.

Review the RCM Assessment Workbook: The RCM (Release Certification Matrix) Assessment Workbook is a tool used during the upgrade process of VxBlock systems1.

Understand the Workbook’s Purpose: Its primary use is to identify items and components within the VxBlock system that require remediation before an upgrade can be performed1.

Utilize the Workbook: By using the RCM Assessment Workbook, engineers can systematically review the current state of the system and pinpoint areas that need attention1.

Ensure Compliance: This step is crucial to ensure that all components meet the necessary standards and are compatible with the new RCM version1.

 VxBlock Central

 Network

 Storage

 Compute

 Virtualization

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.

In the Cisco UCS 6332-16UP 40-Port Fabric Interconnect, unused server ports can be converted to FC (Fibre Channel) ports. This flexibility allows customers to reconfigure ports based on their specific needs, increasing the number of available FC ports when additional FC connectivity is required.

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.

 Cleanup and Run Backups

 Update Checklist

 Complete Project Documentation

 Generate SCR (Service Change Request)

 Provide Documentation

In the Enhanced Knowledge Transfer Phase, the sequence of steps to finalize project deliverables ensures that all necessary tasks are completed in an orderly and efficient manner. Here's a detailed breakdown:

Cleanup and Run Backups:

Explanation: This step involves ensuring that the system and data are clean and backed up. It's crucial to clean up any temporary files or unnecessary data and perform backups to safeguard against data loss.
