You are setting up a customer's 15 headless loT devices that do not support 802.1X..
What should you use?

• A.Multiple Pre-Shared Keys (MPSK) Local
• B.Clearpass with WPA3-PSK
• C.Clearpass with WPA3-AES
• D.Multiple Pre-Shared Keys (MPSK) with WPA3-AES

답을 확인하기

정답:
Explanation:
MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support 802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

Question No : 5

What is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches?

• A.Switch authentication and local forwarding of the voice traffic
• B.Switch authentication and user-based tunneling of the voice traffic.
• C.Central authentication and port-based tunneling of the voice traffic.
• D.Controller authentication and port-based tunneling of all traffic

답을 확인하기

정답:
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.

A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What statements are correct regarding the ERSPAN session that needs to be established on an AOS-CX switch'? (Select two )

• A.On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
• B.The encapsulation protocol used is GR
• C.The encapsulation protocol used is VXLA
• D.The encapsulation protocol is UD
• E.On the source AOS-CX switch, the destination specified is the administrators desktop

답을 확인하기

정답:
Explanation:
These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator's desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc.
The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.
