Dell EMC D-VXB-DY-A-24 Dell VxBlock Deploy Achievement Exam Practice Test

Answer : D

Access SolVe Online: SolVe Online is Dell EMC's online tool that provides step-by-step procedures and support for various products, including VxBlock Systems1.

Navigate to VxBlock Section: Within SolVe Online, navigate to the section dedicated to VxBlock Systems to find resources specific to these models1.

Locate Test Plan: Look for the Test Plan associated with the specific VxBlock model you are working with. The Test Plan is typically available in the form of downloadable documents or guides1.

Download Test Plan: Once located, download the Test Plan for the specific VxBlock model to use as a reference for deployment or troubleshooting1.

Verify with Documentation: Ensure that the downloaded Test Plan matches the model and version of the VxBlock System you are using by cross-referencing with the official documentation1.

Answer : B

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.

Answer : D

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.

Answer : A

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.

Answer : B

Identify the VTEP's role: The VTEP, or VXLAN Tunnel Endpoint, is responsible for encapsulating and de-encapsulating the network traffic sent over the VXLAN1.

Understand NSX Components: The NSX Controller is a key component of the VMware NSX network virtualization platform. It is responsible for the control plane, managing the state of virtual networks and overlay transport zones1.

Communication with VTEP: The NSX Controller communicates with the VTEP to manage the overlay network and ensure that traffic is correctly routed and encapsulated across the network infrastructure1.

Role of other NSX Components: While the NSX Edge provides routing services and the NSX Manager is the centralized management component, it is the NSX Controller that directly manages the state of the virtual network and communicates with the VTEPs1.

Answer : A

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.

Answer : C

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.
