Question 31

A company has Aruba APs that are controlled by Central and that implement WIDS. When you check WIDS events, you see a "detect valid SSID misuse" event. What can you interpret from this event, and what steps should you take?

A.Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat.
B.Admins have likely misconfigured SSID security settings on some of the company's APs. You should have them check those settings.
C.Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event.
D.This event might be a threat but is almost always a false positive. You should wait to see the event over several days before following up on it.

Correct Answer: C

The "Detect Valid SSID Misuse" event in Aruba's Wireless Intrusion Detection System (WIDS) indicates that a valid SSID, associated with your network, is being broadcast from an unauthorized source. This scenario often signals a potential rogue access point attempting to deceive clients into connecting to it (e.g., for credential harvesting or man-in-the-middle attacks).
1. Explanation of Each Option
A: Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat:
* Incorrect:
* This event is not related to authentication failures by legitimate clients.
* Misconfigured authentication settings would lead to events like "authentication failures" or
"radius issues," not "valid SSID misuse."
B: Admins have likely misconfigured SSID security settings on some of the company's APs. You should have them check those settings:
* Incorrect:
* This event refers to an external device broadcasting your SSID, not misconfiguration on the company's authorized APs.
* WIDS differentiates between valid corporate APs and rogue APs.
C: Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event:
* Correct:
* This is the most likely cause of the "detect valid SSID misuse" event. A rogue AP broadcasting a corporate SSID could lure clients into connecting to it, exposing sensitive credentials or traffic.
* Immediate action includes:
* Using the radio information from the event logs to identify the rogue AP's location.
* Physically locating and removing the rogue device.
* Strengthening WIPS/WIDS policies to prevent further misuse.
D: This event might be a threat but is almost always a false positive. You should wait to see the event over several days before following up on it:
* Incorrect:
* While false positives are possible, "valid SSID misuse" is a critical security event that should not be ignored.
* Delaying action increases the risk of successful attacks against your network.
2. Recommended Steps to Address the Event
* Review Event Logs:
* Gather details about the rogue AP, such as SSID, MAC address, channel, and signal strength.
* Locate the Rogue Device:
* Use the detecting AP's radio information and signal strength to triangulate the rogue AP's physical location.
* Respond to the Threat:
* Remove or disable the rogue device.
* Notify the security team for further investigation.
* Prevent Future Misuse:
* Strengthen security policies, such as enabling client whitelists or enhancing WIPS protection.

Question 32

A company wants to implement Virtual Network based Tunneling (VNBT) on a particular group of users and assign those users to an overlay network with VNI
3000.
Assume that an AOS-CX switch is already set up to:
. Implement 802.1X to HPE Aruba Networking ClearPass Policy Manager (CPPM)
. Participate in an EVPN VXLAN solution that includes VNI 3000
Which setting should you configure in the users' AOS-CX role to apply VNBT to them when they connect?

A.Gateway zone set to "3000" with no gateway role set
B.Gateway zone set to "vni-3000" with no gateway role set
C.Access VLAN set to the VLAN mapped to VNI 3000
D.Access VLAN ID set to "3000"

Question 33

A company has several use cases for using its AOS-CX switches' HPE Aruba Networking Network Analytics Engine (NAE).
What is one guideline to keep in mind as you plan?

A.Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.
B.You can install multiple scripts on a switch, but you can deploy only one agent per script.
C.The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
D.When you use custom scripts, you can create as many agents from each script as you want.

Correct Answer: A

The Network Analytics Engine (NAE) in AOS-CX switches provides intelligent monitoring, troubleshooting, and performance analysis through predefined or custom scripts. Here's an analysis of the guidelines for NAE:
A: Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.
* Correct:
* Each AOS-CX switch model has hardware and software limitations, including the number of agents and monitors it supports.
* Monitors are data collection points for tracking specific metrics like interface statistics, CPU usage, or custom-defined parameters.
* Agents are scripts that use monitors to evaluate data, trigger actions, or generate alerts.
* Since one agent can have multiple monitors, the total number of monitors might impact the scalability of agents.
B: You can install multiple scripts on a switch, but you can deploy only one agent per script.
* Incorrect:
* Multiple agents can be deployed from the same script if they monitor different parameters or have different configurations.
* The limitation is usually related to the total number of agents and monitors supported by the switch model, not the script itself.
C: The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
* Incorrect:
* AOS-CX enforces hardware and software limits on the number of agents and monitors. These limits are designed to prevent degradation of switch performance.
* You cannot deploy an unlimited number of agents, as the system enforces these restrictions.
D: When you use custom scripts, you can create as many agents from each script as you want.
* Incorrect:
* While you can use custom scripts to create agents, the total number of agents is subject to the switch's maximum supported limits.
* The scalability of agents is still bound by hardware and software constraints, even with custom scripts.

Question 34

You have downloaded a packet capture that you generated on HPE Aruba Networking Central. When you open the capture in Wireshark, you see the output shown in the exhibit.
What should you do in Wireshark so that you can better interpret the packets?

A.Choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0.
B.Edit preferences for IEEE 802.11 and chose to ignore the Protection bit with IV.
C.Apply the following display filter: wlan.fc.type == 1.
D.Edit the Enabled Protocols and make sure that 802.11, GRE, and Aruba_ERM are enabled.

Question 35

A port-access role for AOS-CX switches has this policy applied to it:
plaintext
Copy code
port-access policy mypolicy
10 class ip zoneC action drop
20 class ip zoneA action drop
100 class ip zoneB
The classes have this configuration:
plaintext
Copy code
class ip zoneC
10 match tcp 10.2.0.0/16 eq https
class ip zoneA
10 match ip any 10.1.0.0/16
class ip zoneB
10 match ip any 10.0.0.0/8
The company wants to permit clients in this role to access 10.2.12.0/24 with HTTPS. What should you do?

A.Add this rule to zoneC: 5 match any 10.2.12.0/24 eq https
B.Add this rule to zoneA: 5 ignore tcp any 10.2.12.0/24 eq https
C.Add this rule to zoneB: 5 match tcp any 10.2.12.0/24 eq https
D.Add this rule to zoneC: 5 ignore tcp any 10.2.12.0/24 eq https
