Set the Service Type to Other.

Set Promiscuous Mode to True.

subinterface with VXLAN tagging

subinterface with 802.1Q tagging

FEX host interface

out of band interface

Switch Virtual Interface

Question # 8

Refer to the exhibit. The default route is not present in the routing tables of the Cisco ACI leaf switches. All static and direct routes are currently being redistributed and advertised. Which jn must be taken to advertise a default route on the eBGP L30ut?

Configure a static default route on the ACI node profiles with next-hop null.

Create a Default Route Leak Policy on the L3Qut.

Enable a BGP peer prefix policy set to Always.

Implement an export route map matching 0.0.0.0/0.

Question # 9

An engineer configures port-12 on Leaf-101 and Leaf-102 to connect to a new server, SVR-12. The new server will belong to EPG-12 and use encap VLAN-1212. The engineer configured SVR-12 as a VPC member port and statically bound the VPC member port to EPG-12. Which additional step must the engineer take to configure connectivity?

Create a VPC Explicit Protection Group for EPG-12 and VLAN-1212.

Associate a domain with EPG-12 that is associated with VLAN-1212.

Select VLAN-1212 on the EPG-12 Interface Policy Group.

Configure an LACP Interface Policy and apply it to EPG-12.

Answer:

Explanation:

The engineer configures port 1/2 on Leaf-101 and Leaf-102 to connect to a new server (SVR-12), which belongs to EPG-12 using VLAN-1212 encapsulation. The server is configured as a vPC member port and statically bound to EPG-12. The task is to ensure connectivity, indicating a missing configuration step.

Requirement Analysis

Static binding of a vPC member port to an EPG requires proper VLAN association and domain mapping.

vPC ensures redundancy, and the VLAN (1212) must be allocated and associated with the EPG via a domain (e.g., VMM or physical domain).

Option Evaluation

A. Create a VPC Explicit Protection Group for EPG-12 and VLAN-1212 :

vPC Explicit Protection Groups are used for specific vPC configurations, but this is not a standard requirement for EPG binding and VLAN association.

[: Cisco ACI vPC Configuration Guide., B. Associate a domain with EPG-12 that is associated with VLAN-1212: , Associating a domain (e.g., VMM or physical domain) with EPG-12 and mapping VLAN-1212 ensures the VLAN is allocated and recognized by the fabric for the vPC ports. This is a critical step for static binding to work., Reference: Cisco APIC EPG Configuration Guide, "Domain and VLAN Association.", C. Select VLAN-1212 on the EPG-12 Interface Policy Group: , The Interface Policy Group defines port settings, but VLAN selection is managed via the domain association, not the policy group alone. This is insufficient., Reference: Cisco ACI Interface Policy Configuration Guide., D. Configure an LACP Interface Policy and apply it to EPG-12: , LACP is optional for vPC and not required for static EPG binding. The issue is VLAN/domain association, not link aggregation., Reference: Cisco ACI LACP Configuration Guide., Final Answer Justification, B is correct because associating a domain with EPG-12 and VLAN-1212 ensures the fabric recognizes the VLAN encapsulation and applies the EPG configuration to the vPC ports., Primary Cisco References: , Cisco APIC vPC Deployment Guide., Cisco ACI EPG and Domain Configuration Guide., , ]

Question # 10

A customer migrates a legacy environment to Cisco ACI. A Layer 2 trunk is configured to interconnect the two

environments. The customer also builds ACI fabric in an application-centric mode. Which feature should be

enabled in the bridge domain to reduce instability during the migration?

Set Multi-Destination Flooding to Flood in BD.

Enable Flood in Encapsulation.

Set Multi-Destination Flooding to Flood in Encapsulation.

Disable Endpoint Dataplane Learning
