A customer has an AOS 10-based solution, including Aruba APs. The customer wants to use Cloud Auth to authenticate non-802.1X capable IoT devices.
What is a prerequisite for setting up the device role mappings?
Option A is incorrect because NetConductor is not related to Cloud Authentication and Policy. NetConductor is a cloud-based network management solution that simplifies the deployment and operation of Aruba Instant networks.
Option C is incorrect because integrating Aruba ClearPass Policy Manager (CPPM) and Device Insight is not a prerequisite for setting up the device role mappings. CPPM and Device Insight can work together to provide enhanced visibility and control over IoT devices, but they are not required for Cloud Authentication and Policy.
Option D is incorrect because creating global role-to-role firewall policies in Central is not a prerequisite for setting up the device role mappings. Global role-to-role firewall policies are used to define the traffic rules between different client roles across the entire network, but they are not required for Cloud Authentication and Policy.
Refer to the scenario.
A customer has an Aruba ClearPass cluster. The customer has AOS-CX switches that implement 802.1X authentication to ClearPass Policy Manager (CPPM).
Switches are using local port-access policies.
The customer wants to start tunneling wired clients that pass user authentication only to an Aruba gateway cluster. The gateway cluster should assign these clients to the ''eth-internet" role. The gateway should also handle assigning clients to their VLAN, which is VLAN 20.
The plan for the enforcement policy and profiles is shown below:
The gateway cluster has two gateways with these IP addresses:
* Gateway 1
o VLAN 4085 (system IP) = 10.20.4.21
o VLAN 20 (users) = 10.20.20.1
o VLAN 4094 (WAN) = 198.51.100.14
* Gateway 2
o VLAN 4085 (system IP) = 10.20.4.22
o VLAN 20 (users) = 10.20.20.2
o VLAN 4094 (WAN) = 198.51.100.12
* VRRP on VLAN 20 = 10.20.20.254
The customer requires high availability for the tunnels between the switches and the gateway cluster. If one gateway falls, the other gateway should take over its tunnels. Also, the switch should be able to discover the gateway cluster regardless of whether one of the gateways is in the cluster.
Assume that you have configured the correct UBT zone and port-access role settings. However, the solution is not working.
What else should you make sure to do?
The correct answer is B. Create a new VLAN on the AOS-CX switch and configure that VLAN as the UBT client VLAN.
The other options are not correct or relevant for this issue:
Option C is not correct because VIA licenses are not required for UBT. VIA licenses are required for enabling VPN services on Aruba Mobility Controllers for remote access clients using Aruba Virtual Intranet Access (VIA) software . VIA licenses are not related to UBT or wired clients.
Option D is not correct because changing the port-access auth-mode mode to client-mode on any edge ports to which tunneled clients might connect would not affect UBT. The port-access auth-mode mode determines how a port handles authentication requests from multiple clients connected to a single port . Client-mode is the default mode that allows only one client per port, while multi-client-mode allows multiple clients per port. The port-access auth-mode mode does not affect how UBT works or how traffic is tunneled from a port.
A company has an Aruba ClearPass server at 10.47.47.8, FQDN radius.acnsxtest.local. This exhibit shows ClearPass Policy Manager's (CPPM's) settings for an Aruba Mobility Controller (MC).
The MC is already configured with RADIUS authentication settings for CPPM, and RADIUS requests between the MC and CPPM are working. A network admin enters and commits this command to enable dynamic authorization on the MC:
aaa rfc-3576-server 10.47.47.8
But when CPPM sends CoA requests to the MC, they are not working. This exhibit shows the RFC 3576 server statistics on the MC:
How could you fix this issue?
In this scenario, the MC is configured with the IP address of the CPPM server (10.47.47.8) as the RFC 3576 server, but it is using the default UDP port of 3799. However, according to the exhibit, the CPPM server is using a different UDP port of 1700 for dynamic authorization . This mismatch causes the CoA requests from CPPM to fail on the MC, as shown by the statistics .
Refer to the exhibit.
Which IP address should you record as a possibly compromised client?
The exhibit shows a screenshot of a Malwarebytes alert that indicates that a website was blocked due to compromise. The alert contains the following information:
The type of protection: Web Protection
The website that was blocked: 10.254.1.21
The port that was used: 80
The process that initiated the connection: C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
The IP address of the device that initiated the connection: 10.1.26.151
The IP address of the device that initiated the connection is the one that should be recorded as a possibly compromised client, as it indicates that the device tried to access a malicious website that could infect it with malware or steal its data. In this case, the IP address of the possibly compromised client is 10.1.26.151.
A customer's admins have added RF Protect licenses and enabled WIDS for a customer's AOS 8-based solution. The customer wants to use the built-in capabilities of APs without deploying dedicated air monitors (AMs). Admins tested rogue AP detection by connecting an unauthorized wireless AP to a switch. The rogue AP was not detected even after several hours.
What is one point about which you should ask?
RF Protect is a feature that enables wireless intrusion detection and prevention system (WIDS/WIPS) capabilities on AOS 8-based solutions. WIDS/WIPS allows detecting and mitigating rogue APs, unauthorized clients, and other wireless threats. RF Protect requires RF Protect licenses to be installed and WIDS to be enabled on the Mobility Master (MM).
To use the built-in capabilities of APs for WIDS/WIPS, without deploying dedicated air monitors (AMs), admins need to set at least one radio on each AP to air monitor mode. Air monitor mode allows the AP to scan the wireless spectrum and report any wireless activity or anomalies to the MM. Air monitor mode does not affect the other radio on the AP, which can still serve clients in access mode. By setting at least one radio on each AP to air monitor mode, admins can achieve full coverage and visibility of the wireless environment and detect rogue APs.
If admins do not set any radio on the APs to air monitor mode, the APs will not scan the wireless spectrum or report any wireless activity or anomalies to the MM. This means that the APs will not be able to detect rogue APs, even if they are connected to the same network. Therefore, admins should check whether they have set at least one radio on each AP to air monitor mode.
