Question 6 of 92

An NSX administrator wants to create a Tier-0 Gateway to support equal cost multi-path (ECMP) routing.

Which failover detection protocol must be used to meet this requirement?

Answer

Suggested Answer

The suggested answer is C.

Bidirectional Forwarding Detection (BFD) is a protocol designed to detect faults in the path between two forwarding engines, including interfaces, data links, and forwarding planes. It is highly effective for quick failover detections and supports equal cost multi-path (ECMP) routing, which makes it the mandatory protocol for meeting the requirement of creating a Tier-0 Gateway for ECMP routing.

What are two supported N-VDS modes? (Choose two.)

Answer

Suggested Answer

The suggested answer is D, E.

Two supported N-VDS modes are Enhanced Datapath and Standard Datapath. Enhanced Datapath is optimized for performance, typically used for NFV use cases while Standard Datapath offers the regular data path capabilities for general networking needs. These modes provide different sets of features and performance options to suit various deployment scenarios.

A user is assigned these two roles in NSX Manager:

  • LB Admin
  • Network Engineer

What privileges does this user have in the system?

Answer

Suggested Answer

The suggested answer is A.

A user assigned the roles of LB Admin and Network Engineer would have read permissions on all networking services and full access permissions on load balancing features. The LB Admin role provides full access to load balancing features, while the Network Engineer role typically offers read permissions on all networking services. Combining these roles results in read access for networking services and full access for load balancing features.

An NSX administrator has configured a KVM hypervisor as a transport node.

Which kernel module on KVM implements a N-VDS?

Answer

Suggested Answer

The suggested answer is A.

An N-VDS on a KVM hypervisor is implemented using the 'openvswitch' kernel module. Open vSwitch (OVS) is a production-quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extensions, while still supporting standard management interfaces and protocols. As such, it is commonly employed in KVM environments to handle network traffic.

Which CLI command should be executed on a KVM hypervisor to retrieve the VM interface UUID?

Answer

Suggested Answer

The suggested answer is A.

To retrieve the VM interface UUID on a KVM hypervisor, the correct command would be one that inspects the XML configuration of the virtual machine and filters out the relevant information. The command 'virsh dumpxml | grep interfaceid' is appropriate for this as 'virsh dumpxml' outputs the complete XML configuration of the specified virtual machine, and using 'grep interfaceid' filters the output to display lines containing the interface UUID.
