You cannot leak multicast routes is a rule for the setup of multi-protocol BGP to implement dynamic VRF route leaking on an ArubaOS-CX switch. Multi-protocol BGP only supports unicast routes for route leaking, and multicast routes are not leaked between VRFs1.

Setting up dedicated switches to connect to iSCSI arrays and connecting top of rack (ToR) switches, which will support both data and storage traffic, to those dedicated switches is a best practice for supporting the iSCSI requirements. This provides isolation and security for the iSCSI traffic and reduces the risk of congestion or latency on the storage network1.

The solution is correct because using the same speed on every link in the ISL is a guideline for establishing a VSX ISL between two ArubaOS-CX switches. Using the same speed on every link in the ISL ensures consistent performance and avoids potential issues with link aggregation. Therefore, using the same speed on every link in the ISL is a good practice for establishing a VSX ISL.

VTEPs that use headend replication forward unicasts with unknown destination MAC addresses as unicast packets to each VTEP in the same VNI is a correct description of how the VTEPs handle VXLAN traffic forwarding. Headend replication is a method of replicating VXLAN packets at the ingress VTEP instead of using multicast routing. The ingress VTEP sends a copy of the VXLAN packet to each egress VTEP that belongs to the same VNI using unicast tunnels1.

Deploying Aruba 83xx switches as data center leaf switches is not how you should position switches in the ArubaOS-CX portfolio for data center networks. The Aruba 83xx switches are designed for data center spine or core roles, and they provide high performance, scalability, and resiliency. The Aruba 63xx switches are more suitable for data center leaf roles, and they provide high density, low latency, and advanced features such as VSX and EVPN2.

The solution is incorrect because Switch-1 and Switch-2 implement VXLAN without EVPN, which means they do not have a control plane to exchange MAC addresses. Therefore, the first time that Server 1 communicates with Server 3, it sends an ARP request to resolve Server 3's IP address, not MAC address. The ARP request is encapsulated in a VXLAN header and sent to the VTEP of Switch-2, which decapsulates it and forwards it to Server 3.

The solution is incorrect because enabling the REST interface in read-only mode is not a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses the REST interface to configure the switch, so it needs write access as well as read access. Therefore, enabling the REST interface in read-write mode is a minimum requirement for setting up communications between the switch and NetEdit.

The solution is correct because making sure that the SSH server is enabled is a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses SSH to establish a secure connection to the switch and execute commands on it. Therefore, making sure that the SSH server is enabled is necessary for setting up communications between the switch and NetEdit.

The ArubaOS-CX software is based on the ArubaOS-Switch software and adds data center features is not a correct description of the ArubaOS-CX architecture. The ArubaOS-CX software is a new operating system that is designed for data center and campus networks. It is not based on the ArubaOS-Switch software, which is used for legacy campus switches. The ArubaOS-CX software provides advanced features such as VSX, EVPN, NAE, REST APIs, etc1.
