Exam 300-620 topic 1 question 239 discussion

Actual exam question from Cisco's 300-620
Question #: 239
Topic #: 1
[All 300-620 Questions]

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:

• The external switch interface must use 802.1Q tagging.
• Access to the Internet for the ACI fabric must be the L3Out.
• 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.
