Questions # 25:

Question # 25

Refer to the exhibit. Server A is connected to the Cisco ACI fabric using two teamed interfaces. One interface in a team is configured as active and the other remains in standby mode. When a failover occurs and the standby interface becomes active, it uses its built-in MAC address to send traffic. Which bridge domain configuration must be applied to resolve the issue?

Options:

Configure Hardware proxy.

Set L2 Unknown Unicast to Flood.

Enable ARP flooding.

Activate Limit IP Learning to Subnet.

Questions # 26:

An ACI administrator notices a change in the behavior of the fabric. Which action must be taken to determine if a human intervention introduced the change?

Options:

Inspect event records in the APIC UI to see all actions performed by users.

Inspect /var/log/audit_messages on the APIC to see a record of all user actions.

Inspect audit logs in the APIC UI to see all user events.

Inspect the output of show command history in the APIC CLI.

Questions # 27:

Which two dynamic routing protocols are supported when using Cisco ACI to connect to an external Layer 3 network? (Choose two.)

Questions # 28:

An engineer needs to avoid loops in the ACI network and needs an ACI leaf switch to error-disable an interface if the interface receives an ACI-generated packet. Which action meets these requirements?

Options:

Enable the Loop Indication by MCP event in the Error Disabled Recovery Policy.

Set Rogue EP Control in the Endpoint Controls Policy.

Uncheck the Loop Protection Action check box in MCP Instance Policy.

Change the default administrative state of the global MCP Instance Policy.

Questions # 29:

An ACI engineer is implementing a Layer 3 out inside the Cisco ACI fabric that must meet these requirements:

The data center core switch must be connected to one of the leaf switches with a single 1G link.

The routes must be exchanged using a link-state routing protocol that supports hierarchical network design.

The data center core switch interface must be using 802.1Q tagging, and each vlan will be configured with a dedicated IP address.

Which set of steps accomplishes these goals?

Options:

Create an External Bridged Network using the configured VLAN pool.

Build the Leaf profile, selecting Routed sub-interface and the appropriate VLAN.

Configure the OSPF Protocol policy with an area of 0.

Create Routed Outside object and Node Profile, selecting OSPF as the routing protocol. Build the Interface profile, selecting Routed Sub-interface and the appropriate VLAN. Configure the External Network object with a network of 0.0.0.0/0.

Set up the ElGRP Protocol policy with the selected Autonomous System number. Create the Routed Outside object and Node Profile selecting ElGRP Configure the Interface profile selecting Routed Interface and the appropriate interfaces. Create the External Network object with a network of 0.0.0.0/0.

Questions # 30:

Which switch type is discovered first in the Cisco ACI fabric discovery process?

Options:

leaf

access

distribution

spine

Answer

Explanation

The question asks which switch type is discovered first in the Cisco ACI fabric discovery process. The ACI fabric consists of spine and leaf switches, and the discovery process is a critical initial step to establish the fabric topology. Let’s analyze this based on Cisco ACI documentation.

Requirement Analysis

The ACI fabric discovery process involves the Application Policy Infrastructure Controller (APIC) identifying and registering switches to form the network topology.

The process relies on protocols like Link Layer Discovery Protocol (LLDP) and Cisco Discovery Protocol (CDP) to detect connected devices.

The sequence of discovery is determined by the physical connectivity and the role of switches in the fabric.

Option Evaluation

A. leaf:

In the Cisco ACI fabric, the discovery process begins with the leaf switches. When the APIC is powered on and connected to the fabric, it first discovers the leaf switches directly attached to it or other initial points of connectivity. Leaf switches are the access layer devices that connect endpoints and are the starting point for fabric topology discovery. Once leaf switches are identified, they assist in discovering the spine switches.

[: Cisco APIC Installation and Setup Guide, "Fabric Discovery Process" and Cisco ACI Fabric Fundamentals, "Switch Discovery.", B. access: , "Access" is not a specific switch type in the ACI fabric context. It may refer to external access switches, but these are not part of the initial fabric discovery process, which focuses on spine and leaf switches., Reference: Not applicable to ACI fabric discovery., C. distribution: , "Distribution" is a traditional network layer, but it does not apply to the ACI fabric, which uses a spine-leaf architecture. This option is irrelevant., Reference: Not applicable to ACI., D. spine: , Spine switches are discovered after the leaf switches because the leaf switches provide the connectivity path to the spines. The APIC uses the leaf switches to map the spine layer in the fabric topology., Reference: Cisco ACI Architecture White Paper, "Spine-Leaf Discovery Sequence.", Final Answer Justification, A is correct because the ACI fabric discovery process starts with the leaf switches. The APIC initially detects leaf switches connected to it or other initial points, and then uses this information to discover the spine switches, establishing the full fabric topology., Primary Cisco References: , Cisco APIC Getting Started Guide, "Fabric Bring-Up and Discovery.", Cisco ACI Design Guide, "Fabric Discovery Process.", ]
