HP Aruba Certified Network Security Associate Exam Sample Questions (Q102-Q107):

NEW QUESTION # 102
This company has AOS-CX switches. The exhibit shows one access layer switch, Switch-2, as an example, but the campus actually has more switches. Switch-1 is a core switch that acts as the default router for end-user devices.
What is a correct way to configure the switches to protect against exploits from untrusted end-user devices?

A. On Switch-2, enable DHCP snooping globally and on VLANs 15 and 25. Later, enable ARP inspection on the same VLANs.
B. On Switch-1, enable DHCP snooping on VLAN 100 and ARP inspection on VLANs 15 and 25.
C. On Switch-2, enable BPDU filtering on all edge ports in order to prevent eavesdropping attacks by untrusted devices.
D. On Switch-1, enable ARP inspection on VLAN 100 and DHCP snooping on VLANs 15 and 25.

Answer: A

Explanation:
The scenario involves AOS-CX switches in a two-tier topology with Switch-1 as the core switch (default router) on VLAN 100 and Switch-2 as an access layer switch with VLANs 15 and 25, where end-user devices connect. The goal is to protect against exploits from untrusted end-user devices, such as DHCP spoofing or ARP poisoning attacks, which are common threats in access layer networks.
DHCP Snooping: This feature protects against rogue DHCP servers by filtering DHCP messages. It should be enabled on the access layer switch (Switch-2) where end-user devices connect, specifically on the VLANs where these devices reside (VLANs 15 and 25). DHCP snooping builds a binding table of legitimate IP-to-MAC mappings, which can be used by other features like ARP inspection.
ARP Inspection: This feature prevents ARP poisoning attacks by validating ARP packets against the DHCP snooping binding table. It should also be enabled on the access layer switch (Switch-2) on VLANs 15 and 25, where untrusted devices are connected.
Option B, "On Switch-2, enable DHCP snooping globally and on VLANs 15 and 25. Later, enable ARP inspection on the same VLANs," is correct. DHCP snooping must be enabled first to build the binding table, and then ARP inspection can use this table to validate ARP packets. This configuration should be applied on Switch-2, the access layer switch, because that's where untrusted end-user devices connect.
Option A, "On Switch-1, enable ARP inspection on VLAN 100 and DHCP snooping on VLANs 15 and 25," is incorrect. Switch-1 is the core switch and does not directly connect to end-user devices on VLANs 15 and 25. DHCP snooping and ARP inspection should be enabled on the access layer switch (Switch-2) where the devices reside. Additionally, enabling ARP inspection on VLAN 100 (where the DHCP server is) is unnecessary since the DHCP server is a trusted device.
Option C, "On Switch-2, enable BPDU filtering on all edge ports in order to prevent eavesdropping attacks by untrusted devices," is incorrect. BPDU filtering is used to prevent spanning tree protocol (STP) attacks by blocking BPDUs on edge ports, but it does not protect against eavesdropping or other exploits like DHCP spoofing or ARP poisoning, which are more relevant in this context.
Option D, "On Switch-1, enable DHCP snooping on VLAN 100 and ARP inspection on VLANs 15 and 25," is incorrect for the same reason as Option A. Switch-1 is not the appropriate place to enable these features since it's not directly connected to the untrusted devices on VLANs 15 and 25.
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"DHCP snooping should be enabled on access layer switches where untrusted end-user devices connect. It must be enabled globally and on the specific VLANs where the devices reside (e.g., dhcp-snooping vlan 15,25). This feature builds a binding table of IP-to-MAC mappings, which can be used by Dynamic ARP Inspection (DAI) to prevent ARP poisoning attacks. DAI should also be enabled on the same VLANs (e.g., ip arp inspection vlan 15,25) after DHCP snooping is configured, ensuring that ARP packets are validated against the DHCP snooping binding table." (Page 145, DHCP Snooping and ARP Inspection Section) Additionally, the guide notes:
"Dynamic ARP Inspection (DAI) and DHCP snooping are typically configured on access layer switches to protect against exploits from untrusted devices, such as DHCP spoofing and ARP poisoning. These features should be applied to the VLANs where end-user devices connect, not on core switches unless those VLANs are directly connected to untrusted devices." (Page 146, Best Practices Section)

NEW QUESTION # 103
What role does the Aruba ClearPass Device Insight Analyzer play in the Device Insight architecture?

A. It resides on-prem and is responsible for running active SNMP and Nmap scans
B. It resides In the cloud and applies machine learning and supervised crowdsourcing to metadata sent by Collectors
C. It resides in the cloud and manages licensing and configuration for Collectors
D. It resides on-prem and provides the span port to which traffic is mirrored for deep analytics.

Answer: B

Explanation:
The Aruba ClearPass Device Insight Analyzer plays a crucial role within the Device Insight architecture by residing in the cloud and applying machine learning and supervised crowdsourcing to the metadata sent by Collectors. This component of the architecture is responsible for analyzing vast amounts of data collected from the network to identify and classify devices accurately. By utilizing machine learning algorithms and crowdsourced input, the Device Insight Analyzer enhances the accuracy of device detection and classification, thereby improving the overall security and management of the network.
References:
Aruba ClearPass official documentation and whitepapers that detail the functionality and deployment of the Device Insight Analyzer.
Technical articles and presentations on network security solutions that discuss the use of machine learning and data analytics in device management.

NEW QUESTION # 104
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?

A. Create a dynamic authorization, or RFC 3576, server with the 10.5.5.5 address and correct shared secret.
B. Enable the dynamic authorization setting in the "clearpass" authentication server settings.
C. Configure a ClearPass username and password in the MyEmployees AAA profile.
D. Install the root CA associated with the 10 5.5.5 server's certificate as a Trusted CA certificate.

Answer: A

Explanation:
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.

NEW QUESTION # 105
Your ArubaoS solution has detected a rogue AP with Wireless intrusion Prevention (WIP). Which information about the detected radio can best help you to locate the rogue device?

A. the confidence level
B. the match type
C. the match method
D. the detecting devices

Answer: C

NEW QUESTION # 106
What is one practice that can help you to maintain a digital chain or custody In your network?

A. Enable packet capturing on Instant AP or Moodily Controller (MC) datepath on an ongoing basis
B. Ensure that all network infrastructure devices receive a valid clock using authenticated NTP
C. Enable packet capturing on Instant AP or Mobility Controller (MC) control path on an ongoing basis.
D. Ensure that all network Infrastructure devices use RADIUS rather than TACACS+ to authenticate managers

Answer: B

Explanation:
To maintain a digital chain of custody in a network, a crucial practice is to ensure that all network infrastructure devices receive a valid clock using authenticated Network Time Protocol (NTP). Accurate and synchronized time stamps are essential for creating reliable and legally defensible logs. Authenticated NTP ensures that the time being set on devices is accurate and that the time source is verified, which is necessary for correlating logs from different devices and for forensic analysis.
:
Digital forensics and network security protocols that underscore the importance of accurate timekeeping for maintaining a digital chain of custody.
NTP configuration guidelines for network devices, emphasizing the use of authentication to prevent tampering with clock settings.
