 This is because this URI specifies the exact attribute that contains the number of access rejects from the RADIUS server, which is the information that the NAE script needs to monitor and trigger an alert.

A. /rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics. This is not the correct URI because it returns the entire authstatistics object, which contains more information than the access rejects, such as access accepts, challenges, timeouts, etc. This might make the NAE script more complex and inefficient to parse and process the data.

B. /rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics?attributes=access_rejects. This is not a valid URI because it has two question marks, which is a syntax error. The question mark is used to indicate the start of the query string, which can have one or more parameters separated by ampersands. The correct way to specify multiple attributes is to use a comma-separated list after the question mark, such as ?attributes=attr1,attr2,attr3.

C. /rest/v1/system/vrfs/mgmt/radius/_servers/cp.acnsxtest.local/2083/tcp. This is not a valid URI because it has an extra underscore before servers, which is a typo. The correct resource name is servers, not _servers. Moreover, this URI does not specify any attributes, which means it will return the default attributes of the RADIUS server object, such as name, port, protocol, etc., but not the authstatistics or access_rejects.

According to the ClearPass Policy Manager User Guide1, userAccountControl is a custom attribute in Active Directory that contains a set of flags that define the properties and behavior of user accounts. One of these flags is ACCOUNTDISABLE, which indicates whether the account is disabled or not. By adding this attribute to the filters in the AD authentication source, CPPM can retrieve this attribute for each user and use it as a condition in the enforcement policies to prevent users with disabled accounts from connecting even if they have valid certificates. Therefore, option C is the correct answer.

Alert duration and threshold settings are used to control how often and under what conditions email notifications are sent for gateway IDS/IPS events 1. By adjusting these settings, the customer can reduce the frequency of repeat email notifications for the same threat, while still being informed of any critical or new threats.

To adjust the alert duration and threshold settings in Aruba Central, the customer can follow these steps 1:

• In the Aruba Central app, set the filter to Global, a group, or a device.
• Under Analyze, click Alerts & Events.
• Click the Config icon to open the Alert Severities & Notifications page.
• Select the Gateway IDS/IPS tab to view the alert categories and severities for gateway IDS/IPS events.
• Click on an alert category to expand it and view the alert duration and threshold settings for each severity level.
• Enter a value in minutes for the alert duration. This is the time period during which the alert is active and email notifications are sent.
• Enter a value for the alert threshold. This is the number of times the alert must be triggered within the alert duration before an email notification is sent.
• Click Save.

By increasing the alert duration and/or threshold values, the customer can reduce the number of email notifications for recurring threats, as they will only be sent when the threshold is reached within the duration. For example, if the customer sets the alert duration to 60 minutes and the alert threshold to 10 for a Critical severity level, then an email notification will only be sent if the same threat occurs 10 times or more within an hour.
