Cisco 300-620 Exam Questions & Answers

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

A. enable Limit IP Learning to Subnet

B. enable Unicast Routing

C. enable IP Data-plane Learning

D. enable ARP Flooding to BD

When a pre-provision immediacy is used, when is the policy downloaded to the Cisco ACI leaf switch?

A. The policy is downloaded and programmed in the hardware policy CAM when the change is implemented on the Cisco APIC.

B. The policy is programmed in the hardware policy CAM when the policy is downloaded in the leaf software.

C. The policy is programmed in the hardware policy CAM when the first packet is received through the data path.

D. The policy is downloaded to the associated leaf switch software when the ESXi host is attached to a DVS.

A network engineer is implementing a Layer 3 Out in the Cisco ACI fabric. The data center core switches must connect to a pair of leaf switches and exchange routes via a routing protocol. In addition, the implementation must meet these criteria:

1.

The external switch interface must use 802.1Q tagging.

2.

Access to the Internet for the ACI fabric must be the L3Out.

3.

The L3Out must use a routing protocol that has rapid convergence time and low CPU usage.

Which configuration set meets these requirements?

A. Configure the OSPF Protocol policy with an area of 0. Set up the Routed External Network object and Node Profile and select OSPF. Create the Switch profile and select VPC with the appropriate interfaces. Create the default network and associate it with the Routed Outside object.

B. Configure the BGP Protocol policy with the appropriate Autonomous System number.

Configure an Interface policy and an External Bridged Domain.

Create an External Bridged Network and use the configured VLAN pool.

Build the Leaf profile and select the Routed sub-interface with the appropriate VLAN.

C. Implement the IS-IS Protocol policy with the selected Autonomous System number. Create the Routed Outside object and Node Profile and select IS-IS. Configure the Interface profile and select the Routed Interface with the appropriate interfaces. Create the External Network object.

D. Implement the EIGRP Protocol policy with the selected Autonomous System number. Create Routed Outside object and Node Profile and select EIGRP as the routing protocol. Build the Interface profile and select SVI and the appropriate VPC. Configure the External Network object with a network of 0.0.0.0/0.
