To clear the critical fault related to B2B credit oversubscription in the ACI domain connectivity to the fiber channel storage, the value that should be chosen is 5101. This value is set to address the issue of B2B credit oversubscription and clear the critical fault as reported by the client1.

 To have the endpoint table learn the IP addresses of endpoints in a bridge domain, unicast routing must be enabled1. This allows the bridge domain to learn the IP addresses of endpoints through the data plane1.

To create a backup of the Cisco ACI fabric for disaster recovery that is secure, encrypted, and in a format conducive to processing with a Python script, the engineer must select Secure Copy Protocol (SCP) for secure and encrypted transport. The backup file should be in JSON format, which is similar to a Python dictionary and can be easily processed by a Python script. Additionally, enabling Global AES Encryption ensures that all user and password-related information is included securely in the backup1.

To implement a Layer 3 out (L3Out) inside the Cisco ACI fabric that meets the specified requirements, the following steps should be taken:

Configure the OSPF Protocol policy with an area of 0: This step involves setting up OSPF, a link-state routing protocol that supports hierarchical network design, as the routing protocol for the L3Out1.

Create Routed Outside object and Node Profile, selecting OSPF: This step involves creating a Routed Outside object and associating it with a Node Profile that specifies OSPF as the routing protocol1.

Build the Interface profile, selecting Routed Sub-interface and the appropriate VLAN: This step involves creating an Interface profile for the connection to the data center core switch, using 802.1Q tagging for VLAN separation2.

Configure the External Network object with a network of 0.0.0.0/0: This step involves setting up the External Network object to advertise routes to the rest of the network1.
