What are the required settings to meet the requirements of workload migration in Cisco ACI?

Single Choice

The existing network and ACI fabric have been connected to support workload migration. Servers will physically terminate at the Cisco ACI, but their gateway must stay in the existing network. The solution needs to adhere to Cisco s best practices. The engineer started configuring the relevant Bridge Domain and needs to complete the configuration. Which group of settings are required to meet these requirements?

L2 Unknown Unicast: Hardware Proxy
L3 Unknown Multicast Flooding: Flood
Multi Destination Flooding: Flood in BD
ARP Flooding: Enable

Which ACI policies should be configured to control application data flow and enable auto-negotiation?

Multiple Choice

An engineer needs to deploy a leaf access port policy group in ACI Fabric to support the following requirements:

• Control the amount of application data flowing into the system
• Allow the newly connected device to auto-negotiate link speed with the leaf switch

Which two ACI policies must be configured to achieve these requirements? (Choose two.)

link level policy

L2 interface policy

slow drain policy

ingress data plane policing policy

ingress control plane policing policy

How can the responsible user for the disappearance of a port group in vCenter be determined?

Single Choice

The Application team reports that a previously existing port group has disappeared from vCenter. An engineer confirms that the VMM domain association for the EPG is no longer present. Which action determines which user is responsible for the change?

Check the EPG audit logs for the deletion action and compare the affected object and user.

Evaluate the potential faults that are raised for that EPG.

Examine the health score and drill down to an object that affects the EPG combined score.

Inspect the server logs to see who was logging in to the APIC during the last few hours.

How can Cisco APIC configuration prevent learning of unconfigured remote networks on bridge domain?

Single Choice

Which Cisco APIC configuration prevents a remote network that is not configured on the bridge domain from being learned by the fabric?

enable Limit IP Learning to Subnet

enable Unicast Routing

enable IP Data-plane Learning

enable ARP Flooding to BD

What is the recommended upgrade approach for minimizing traffic impact in an ACI fabric with dual-homed servers?

Single Choice

A data center administrator is upgrading an ACI fabric. There are 3 APIC controllers in the fabric and all the servers are dual-homed to pairs of leaf switches configured in VPC mode. How should the fabric be upgraded to minimize possible traffic impact during the upgrade?

1. Create two maintenance groups for the APIC controllers: VPC left and VPC right.
2. Upgrade the first group of controllers.
3. Upgrade the second group of controllers.
4. Upgrade the leaf switches.

What is the purpose of MP-BGP in Cisco ACI fabric?

Single Choice

What is MP-BGP used for in Cisco ACI fabric?

MP-BGP VPNv4 AF is used as protocol on L3Out between a border leaf and an external router

MP-BGP Layer 2 VPN EVPN AF is used to propagate L3Out routes that are received from a border leaf

MP-BGP VPNv4 AF is used to propagate L3Out routes that are received from a border leaf to the fabric

MP-BGP VPNv4 AF is used between spines in an ACI Multi-Pod fabric to propagate the endpoint

What is the MTU value of MP-BGP EVPN control plane packets for communication between spine nodes in different sites in Cisco ACI?

Single Choice

Regarding the MTU value of MP-BGP EVPN control plane packets in Cisco ACI, which statement about communication between spine nodes in different sites is true?

By default, spine nodes generate 9000-bytes packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 9000-bytes packets.

By default, spine nodes generate 1500-bytes packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 1800-bytes packets.

By default, spine nodes generate 1500-bytes packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 1500-bytes packets.

By default, spine nodes generate 9000-bytes packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 9100-bytes packets.
