Question

Which two statements about Node Management Addresses are true? (Choose two.)

Answers

Explanations

A. B. C. D. E.

CE.

Node Management Addresses (NMAs) are IP addresses assigned to the management interfaces of the Cisco ACI fabric nodes, including the APIC, spine switches, and leaf switches. These addresses are used for in-band and out-of-band management traffic. Here are the explanations for each statement:

A. The managed node connectivity group captures the set of nodes that are going to participate in the management network.

This statement is true. A Managed Node Connectivity Group (MNG) is a group of nodes that participate in the management network. It includes the nodes that are reachable through in-band or out-of-band management interfaces. The MNG is defined in the APIC management tenant, and it specifies the policies for communication between the nodes in the group.

B. Node management addresses are configured during the initial APIC and switch setup scripts, and they are not part of APIC policy configuration.

This statement is also true. Node management addresses are assigned during the initial setup of the ACI fabric, and they are not part of the APIC policy configuration. These addresses are used for in-band and out-of-band management traffic, and they are not associated with any specific tenant.

C. Static node management addresses, in-band and out-of-band, are associated with the common tenant.

This statement is false. Static node management addresses are not associated with any specific tenant, including the common tenant. These addresses are used for in-band and out-of-band management traffic and are assigned during the initial setup of the ACI fabric.

D. Static node management addresses support only IPv4 addressing.

This statement is false. Static node management addresses can support both IPv4 and IPv6 addressing.

E. The external management entity instance profile communicates with nodes that are part of the out-of-band management endpoint group.

This statement is true. The External Management Entity (EME) instance profile is used to communicate with the nodes that are part of the out-of-band management endpoint group. The EME is defined in the APIC management tenant and specifies the policies for communication between the external management entities and the ACI fabric.
