How does the ArubaOS firewall determine which rules to apply to a specific client's traffic?

What is a reason to set up a packet capture on an Aruba Mobility Controller (MC)?

A company has Aruba Mobility Controllers (MCs). Aruba campus APs. and ArubaOS-CX switches. Thecompany plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type The ClearPassadmins tell you that they want to run Network scans as part of the solutionWhat should you do to configure the infrastructure to support the scans?

What is social engineering?

Refer to the exhibit: port-access role role1 vlan access 11 port-access role role2 vlan access 12 port-access role role3 vlan access 13 port-access role role4 vlan access 14 aaa authentication port-access dot1x authenticator enable interface 1/1/1 no shutdown no routing vlan access 1 aaa authentication port-access critical-role role1 aaa authentication port-access preauth-role role2 aaa authentication port-access auth-role role3 interface 1/1/2 no shutdown no routing vlan access 1 aaa authentication port-access critical-role role1 aaa authentication port-access preauth-role role2 aaa authentication port-access auth-role role3 The exhibit shows the configuration on an AOS-CX switch. Client1 connects to port 1/1/1 and authenticates to HPE Aruba Networking ClearPass Policy Manager (CPPM). CPPM sends an Access-Accept with this VSA: Aruba-User-Role: role4. Client2 connects to port 1/1/2 and does not attempt to authenticate. To which roles are the users assigned?

Refer to the exhibit. You have set up a RADIUS server on an ArubaOS Mobility Controller (MC) when you created a WLAN named "MyEmployees .You now want to enable the MC to accept change of authorization (CoA) messages from this server for wireless sessions on this WLAN. What Is a part of the setup on the MC? To enable an ArubaOS Mobility Controller (MC) to accept Change of Authorization (CoA) messages from a RADIUS server for wireless sessions on a WLAN, part of the setup on the MC involves creating a dynamic authorization, or RFC 3576, server with the provided IP address (10.5.5.5) and the correct shared secret. This setup allows the MC to handle CoA requests, which are used to change the authorization attributes of a session after it has been authenticated, such as disconnecting a user or changing a user's VLAN assignment.

What is a difference between radius and TACACS+?

You configure an ArubaOS-Switch to enforce 802.1X authentication with ClearPass Policy Manager(CPPM) denned as the RADIUS server Clients cannot authenticate You check Aruba ClearPass AccessTracker and cannot find a record of the authentication attempt.What are two possible problems that have this symptom? (Select two)

You have been asked to send RADIUS debug messages from an AOS-CX switch to a central SIEM server at 10.5.15.6. The server is already defined on the switch with this command:logging 10.5.15.6You enter this command:debug radius allWhat is the correct debug destination?

The monitoring admin has asked you to set up an AOS-CX switch to meet these criteria: Send logs to a SIEM Syslog server at 10.4.13.15 at the standard TCP port (514) Send a log for all events at the "warning" level or above; do not send logs with a lower level than "warning" The switch did not have any "logging" configuration on it. You then entered this command: AOS-CX(config)# logging 10.4.13.15 tcp vrf default What should you do to finish configuring to the requirements?

What is a vulnerability of an unauthenticated Dime - Heliman exchange?

Device A is contacting https://arubapedia.arubanetworks.com. The web server sends a certificate chain. What does the browser do as part of validating the web server certificate? When a device like Device A contacts a secure website and receives a certificate chain from the server, the browser's primary task is to validate the web server's certificate to ensure it is trustworthy. Part of this validation includes checking that the certificate contains a DNS Subject Alternative Name (SAN) that matches the domain name of the website being accessed---in this case, arubapedia.arubanetworks.com. This ensures that the certificate was indeed issued to the entity operating the domain and helps prevent man-in-the-middle attacks where an invalid certificate could be presented by an attacker. The DNS SAN check is critical because it directly ties the digital certificate to the domain it secures, confirming the authenticity of the website to the user's browser.

What is one benefit of enabling Enhanced Secure mode on an AOS-CX switch?

Which attack is an example or social engineering?

What is one practice that can help you to maintain a digital chain of custody in your network?

You need to implement a WPA3-Enterprise network that can also support WPA2- Enterprise clients. What is a valid configuration for the WPA3-Enterprise WLAN?

What is one benefit of enabling Enhanced Secure mode on an AOS-CX switch?

A client has accessed an HTTPS server at myhost1.example.com using Chrome. The server sends a certificate that includes these properties:* Subject name: myhost1.example.com* SAN: DNS: myhost.example.com* Extended Key Usage (EKU): Server authentication* Issuer: MyCA_SigningThe server also sends an intermediate CA certificate for MyCA_Signing which is signed by MyCA. The client’s Trusted CA Certificate list includes MyCA but not MyCA_Issuing.Which factor or factors prevent the client from trusting the certificate?

A user attempts to connect to an SSID configured on an AOS-8 mobility architecture with Mobility Controllers (MCs) and APs. The SSID enforces WPA3-Enterprise security and uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as the authentication server. The WLAN has initial role, logon, and 802.1 X default role, guest.A user attempts to connect to the SSID, and CPPM sends an Access-Accept with an Aruba-User-Role VSA of "contractor," which exists on the MC.What does the MC do?

You have an Aruba solution with multiple Mobility Controllers (MCs) and campus APs. You want to deploy a WPA3-Enterprise WLAN and authenticate users to Aruba ClearPass Policy Manager (CPPM) with EAP-TLS. What is a guideline for ensuring a successful deployment? For WPA3-Enterprise with EAP-TLS, it's crucial that clients have a trusted certificate installed for the authentication process. EAP-TLS relies on a mutual exchange of certificates for authentication. Deploying client certificates signed by a CA that CPPM trusts ensures that the ClearPass Policy Manager can verify the authenticity of the client certificates during the TLS handshake process. Trust in the root CA is typically required for the server side of the authentication process, not the client side, which is covered by the client's own certificate.

Refer to the exhibit.You need to ensure that only management stations in subnet 192.168.1.0/24 can access the ArubaOS-Switches' CLI. Web Ul. and REST interfaces The company also wants to let managers use these stations to access other parts of the network What should you do?

You have been instructed to look in the ArubaOS Security Dashboard's client list. Your goal is to find clients that belong to the company and have connected to devices that might belong to hackers.Which client fits this description?

Refer to the exhibit. You are deploying a new ArubaOS Mobility Controller (MC), which is enforcing authentication to Aruba ClearPass Policy Manager (CPPM). The authentication is not working correctly, and you find the error shown In the exhibit in the CPPM Event Viewer. What should you check?
