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

Review VxBlock System Documentation: The VxBlock System documentation provides detailed information on the integration of VMware NSX within the VxBlock AMP cluster1.

Identify NSX Components: The NSX Manager is the centralized network management component, and NSX Controllers are part of the control plane that manages the network state1.

Understand AMP Cluster Role: The Advanced Management Platform (AMP) cluster within a VxBlock system is designed to host critical management components, including those for NSX1.

Confirm with Official Dell EMC Resources: The Official Dell VxBlock Deploy Achievement document and other Dell EMC resources confirm that the NSX Manager and NSX Controllers run within the VxBlock AMP cluster1.

SMARTPOOL is a licensed feature of Isilon OneFS. It enables the automated tiering of data across different types of storage media within the cluster, optimizing performance and storage efficiency based on data usage patterns.

Understand the role of VLANs: VLANs (Virtual Local Area Networks) are used to segment network traffic.They provide isolation between network segments at the data link layer (Layer 2) of the OSI model1.

Identify the need for isolation: vSwitch port groups are used to segregate network traffic for different virtual machines or services.To ensure that each port group’s traffic is isolated from the others, separate VLAN IDs are assigned1.

Assign unique VLAN IDs: Each vSwitch port group should be assigned a unique VLAN ID to maintain network isolation.This prevents traffic from one port group from being accessible to another1.

Configure the physical switch ports: The physical switch ports that the vSwitch is connected to must be configured to recognize the VLAN IDs used by the vSwitch port groups1.

Validate the configuration: After configuring VLAN IDs, it’s important to validate the configuration to ensure that the network isolation is functioning as intended1.

VxBlock Central requires 3 VMs to support an RCM (Release Certification Matrix) upgrade. These VMs include the various management and orchestration components necessary tofacilitate the upgrade process and ensure that all aspects of the system are correctly monitored and controlled.

To verify that the hosts can communicate with XtremIO in a VxBlock 1000, you can power off a ToR (Top of Rack) switch. This test helps ensure that network redundancy and failover mechanisms are working correctly, confirming that communication is maintained through alternative paths.

The data layout technique used on an Isilon cluster is Forward Correction Error (FEC). This method ensures data integrity and availability by distributing error correction information across the nodes in the cluster, allowing for data recovery in the event of hardware failures.

Information on data protection techniques in distributed storage systems.

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.

When securely connecting to vCenter, the customer engineer needs to provide the correct source and destination port numbers. The valid source port range for secure connections is typically from 49152 to 65535, which are ephemeral ports assigned by the operating system for outbound connections. The destination port for secure connections to vCenter is 443, which is the standard port for HTTPS.

Match each team member with their RACI role as follows:

Project Manager: Primary point of contact; manages overall project and communications

Assessment Team Lead: Ensures proper assessment execution and validates upgrade sequence plan

Assessment Team: Communicates upgrade progress and issues to the PM

Delivery Manager: Transitions requirements and upgrade plan to the upgrade team

Upgrade Team: Point of contact for internal escalations

Project Manager: Primary point of contact; manages overall project and communications

The Project Manager is responsible for overseeing the entire project, coordinating all activities, and serving as the main point of contact for stakeholders.

Assessment Team Lead: Ensures proper assessment execution and validates upgrade sequence plan

The Assessment Team Lead oversees the assessment phase, ensuring that the evaluation is thorough and that the upgrade sequence is properly planned and validated.

Assessment Team: Communicates upgrade progress and issues to the PM

The Assessment Team members are responsible for executing the assessment tasks and reporting progress and any issues encountered to the Project Manager.

Delivery Manager: Transitions requirements and upgrade plan to the upgrade team

The Delivery Manager is responsible for ensuring that all requirements and the upgrade plan are effectively communicated and handed over to the upgrade team for execution.

Upgrade Team: Point of contact for internal escalations

The Upgrade Team handles the actual upgrade process and serves as the primary point of contact for any internal escalations that may arise during the upgrade.
