Dell EMC Dell VxBlock Deploy Achievement Exam Practice Test

Answer : D

Integrating NSX for virtual networking while retaining ACI for physical networking is possible, but it may be cost prohibitive. This approach requires careful planning and management of both virtual and physical network environments, potentially leading to higher operational costs and complexity.

Cost considerations and best practices for hybrid network environments.

Answer : A

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.

Answer : A

Review ACI Fabric Topology: The ACI fabric topology is based on a spine-leaf architecture, which is a scalable, two-layer network topology composed of spine switches and leaf switches1.

Understand Spine-Leaf Benefits: This topology provides high-bandwidth connectivity between leaf switches and spine switches, allowing for efficient data flow across the network1.

Recognize ACI Fabric Design: In an ACI fabric, each leaf switch connects to every spine switch, creating a non-blocking, high-throughput network that supports east-west traffic patterns typical in modern data centers1.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with Cisco's guidelines on ACI fabric, which specify the spine-leaf topology as the standard for ACI deployments1.

Answer : B

Understand ACI Fabric: Cisco's Application Centric Infrastructure (ACI) fabric is designed to be dynamic and flexible, allowing for seamless movement of servers and changes within the fabric1.

Recognize EPG Membership: When a server that is part of an Endpoint Group (EPG) is moved to a different leaf switch and its IP address is changed, the EPG membership remains consistent as long as the server's identity is recognized within the ACI fabric1.

Identify Port Configuration: The correct port configuration is pushed from the Application Policy Infrastructure Controller (APIC), which updates the fabric about the server's new location and IP address1.

Confirm No Further Changes Needed: Once the APIC has the updated information, no additional configuration changes are required on the ACI fabric.The fabric automatically adjusts to the server's new location and IP address within the same EPG1.

Answer : D

The standard expected timeline to complete an RCM (Release Certification Matrix) upgrade is 3 weeks. This timeline accounts for the necessary planning, execution, and validation steps to ensure a successful upgrade.

Answer : C

Identify VxBlock Central Components: VxBlock Central is a unified interface and access point for converged infrastructure operations1.

Recognize VMs in VxBlock Central: The VMs that are part of VxBlock Central include the Core, Multi-system Management (MSM), and Multi-system Prepositioning (MSP)2.

Understand VM Functions:

The Core VM provides the central point for management and operations within VxBlock Central.

MSM (Multi-system Management) allows for the management of multiple systems within the VxBlock environment.

MSP (Multi-system Prepositioning) is used for staging updates and patches before they are deployed across the systems2.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document details the VMs included in VxBlock Central and their respective roles within the infrastructure2.

Answer : A

In a VxBlock system, the NSX Controller resides in the Management cluster. The Management cluster is responsible for housing management components and services, ensuring centralized control and management of the NSX environment.
