The free HPE7-A01: Aruba Certified Campus Access Professional questions that deal with switches, with answers and explanations. The full bank and the timed practice test cover every topic the exam asks about.
Question #1
Your customer has an Aruba CX 6200F VSF stack with two switches. A third member (JL726A) needs to be added to the VSF configuration. What e the configuration that enables the new devices to join the VSF?
Correct answer: C
Explanation
According to the Aruba Documentation Portal1, the Aruba CX 6200F VSF stack is a feature that allows you to create a virtual switching framework (VSF) with up to eight members that can be managed as a single logical device. The VSF stack provides benefits such as load balancing, failover, redundancy, and security. To add a new device to the VSF stack, you need to configure the device with the VSF command vsf member and specify the type, link, and secondary-member information. The type of the new device can be one of the following: JL726A, JL726B, JL726C, or JL726D. The link is the interface that connects the new device to the existing VSF members. The secondary-member is an optional parameter that specifies which member will act as a backup in case of a failure. 1: https://www.arubanetworks.com/techdocs/AOS-CX/10.06/HTML/5200-7726/index.html 2: https://buy.hpe.com/us/en/networking/switches/fixed-port-l3-managed- ethernet-switches/6000-switch-products/aruba-6200f-48g-4sfp-switch/p/jl726a 3: https://addin.co.th/shop/switch/aruba-switch/6200f-series/jl726a/
Question #2
A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working across the campus which is connected via layer-3. The legacy devices are connected to Aruba CX 6300 switches throughout the campus. Which technology minimizes flooding so the legacy application can work efficiently?
Correct answer: B
Explanation
EVPN-VXLAN is a technology that allows layer-2 communication across layer-3 networks by using Ethernet VPN (EVPN) as a control plane and Virtual Extensible LAN (VXLAN) as a data plane3. EVPN-VXLAN can be used to support legacy applications that communicate at layer-2 across different campuses or data centers that are connected via layer-3. EVPN-VXLAN minimizes flooding by using BGP to distribute MAC addresses and IP addresses of hosts across different VXLAN segments3. EVPN-VXLAN also provides benefits such as loop prevention, load balancing, mobility, and scalability3. References: 3 https://www.arubanetworks.com/assets/tg/TG_EVPN_VXLAN.pdf
Question #3
What is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches?
Correct answer: A
Explanation
This is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches. Dynamic segmentation is a feature that allows AOS-CX switches to tunnel user traffic to a controller or another switch based on user roles and policies. For voice traffic, it is recommended to use switch authentication and local forwarding, which means the voice devices are authenticated by the switch and their traffic is forwarded locally without tunneling. This reduces latency and jitter for voice traffic and improves voice quality. The other options are incorrect because they either use central authentication or tunneling, which are not optimal for voice traffic.
