 The commands shown in the exhibit configure Unicast Reverse Path Forwarding (uRPF) in loose mode on the interface Ethernet 2/2. The ip verify unicast source reachable-via rx command enables uRPF to check that the source address of a received packet has a route in the routing table and that the packet has been received from a valid interface that aligns with the routing table. This helps prevent IP spoofing by ensuring that packets are received from the expected interface.

References := This explanation is based on the principles of uRPF as described in Cisco’s security configuration guides and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials. For more detailed information, please refer to these resources.

The issue with the implementation is that zones are local to the MDS switch, and name service must be used to activate the connection between E ports. In Cisco MDS switches, zoning is enforced at the switch level. Each switch in a fabric can have a different active zone set or none at all. The name server for each switch only contains information about devices that are logged into that specific switch.

 NFS, or Network File System, is a protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS uses remote procedure calls (RPC) over TCP/IP for transport4. References := Wikipedia article on Network File System (NFS)4.

 Option D is the correct statement about the Deployment Immediacy for VMM domains associated to EPGs when the APIC EPG Resolution Immediacy is set to “Immediate”. This means that the policy is pushed to the hardware as soon as the leaf switch is booted, regardless of whether there are any VMs in the EPG or not. This ensures that the policy is ready to be enforced as soon as a VM is created or moved into the EPG. References:
