Is this statement about ARP and ND Suppression true?

Solution: Both ARP-Suppression and ND-Suppression are disabled by default.

  1. Yes
  2. No

Answer(s): B

Explanation:

Both ARP-Suppression and ND-Suppression are disabled by default is not a true statement about ARP and ND Suppression. ARP-Suppression is enabled by default on ArubaOS-CX switches, while ND- Suppression is disabled by default1. ARP-Suppression and ND-Suppression are features that reduce broadcast traffic on VXLAN networks by using a local ARP/ND cache on each switch instead of flooding ARP/ND requests to all VXLAN tunnel endpoints (VTEPs)1.



AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN).

Does this correctly describe how the VTEPs handle VXLAN traffic forwarding?

Solution: VTEPs that use headend replication forward unicasts with unknown destination MAC addresses as unicast packets to each VTEP in the same VNl.

  1. Yes
  2. No

Answer(s): A

Explanation:

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.



Is this how you should position switches in the ArubaOS-CX portfolio for data center networks?

Solution: Deploy Aruba 83xx switches as data center leaf switches.

  1. Yes
  2. No

Answer(s): B

Explanation:

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.



Is this how you should position switches in the ArubaOS-CX portfolio for data center networks?

Solution: Deploy Aruba 83xx switches as core switches for very large three-tier data center networks.

  1. Yes
  2. No

Answer(s): A

Explanation:

Deploying Aruba 83xx switches as core switches for very large three-tier data center networks is 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. They can support very large three-tier data center networks with up to 512 leaf switches using VSX2.



Is this a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface?

Solution: configuring trust of Cos on the interface

  1. Yes
  2. No

Answer(s): A

Explanation:

Configuring trust of CoS on the interface is a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface. PFC is a feature that allows a switch to pause traffic on a per-class basis using IEEE 802.1Qbb frames. To use PFC, the switch must trust the CoS values in the incoming frames and map them to priority groups and queues1.
