HP Aruba Certified Network Security Associate Exam Sample Questions (Q126-Q131):NEW QUESTION # 126
A company has AOS-CX switches deployed in a two-tier topology that uses OSPF routing at the core.
You need to prevent ARP poisoning attacks. To meet this need, what is one technology that you could apply to user VLANs on access layer switches? (Select two.)
  • A. BPDU filtering
  • B. ARP inspection
  • C. DHCPv4 snooping
  • D. OSPF passive interface
  • E. BPDU guard (protection)
Answer: B,C
Explanation:
The scenario involves AOS-CX switches in a two-tier topology (access and core layers) using OSPF routing at the core. The goal is to prevent ARP poisoning attacks on user VLANs at the access layer switches, where end-user devices connect. ARP poisoning (also known as ARP spoofing) is an attack where a malicious device sends fake ARP messages to associate its MAC address with the IP address of another device (e.g., the default gateway), allowing the attacker to intercept traffic.
ARP Inspection (Dynamic ARP Inspection, DAI): This feature prevents ARP poisoning by validating ARP packets against a trusted database of IP-to-MAC bindings. On AOS-CX switches, ARP inspection uses the DHCP snooping binding table to verify that ARP messages come from legitimate devices. If an ARP packet does not match the binding table, it is dropped.
DHCPv4 Snooping: This feature protects against rogue DHCP servers and builds a binding table of legitimate IP-to-MAC mappings by snooping DHCP traffic. The binding table is used by ARP inspection to validate ARP packets. DHCP snooping must be enabled before ARP inspection can function effectively, as it provides the trusted data for validation.
Option A, "ARP inspection," is correct. ARP inspection (DAI) directly prevents ARP poisoning by ensuring that ARP packets are legitimate, making it a key technology for this purpose.
Option B, "OSPF passive interface," is incorrect. OSPF passive interface is used to prevent OSPF from sending routing updates on specific interfaces, typically to reduce routing protocol traffic on user-facing interfaces. It does not prevent ARP poisoning, which is a Layer 2 attack.
Option C, "BPDU guard (protection)," is incorrect. BPDU guard protects against spanning tree protocol (STP) attacks by disabling a port if it receives BPDUs (e.g., from an unauthorized switch). It does not address ARP poisoning, which is unrelated to STP.
Option D, "DHCPv4 snooping," is correct. DHCP snooping is a prerequisite for ARP inspection, as it builds the binding table used to validate ARP packets. It also protects against rogue DHCP servers, which can indirectly contribute to ARP poisoning by assigning incorrect IP addresses.
Option E, "BPDU filtering," is incorrect. BPDU filtering prevents a port from sending or receiving BPDUs, which can be used to protect against STP attacks, but it does not prevent ARP poisoning.
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"To prevent ARP poisoning attacks on user VLANs, enable Dynamic ARP Inspection (DAI) on access layer switches. DAI validates ARP packets against the DHCP snooping binding table to ensure they come from legitimate devices. Use the command ip arp inspection vlan <vlan-list> to enable DAI on the specified VLANs. DHCP snooping must be enabled first with dhcp-snooping and dhcp-snooping vlan <vlan-list> to build the binding table used by DAI." (Page 145, ARP Inspection and DHCP Snooping Section) Additionally, the guide notes:
"DHCP snooping and ARP inspection work together to protect against Layer 2 attacks like ARP poisoning. DHCP snooping builds a trusted database of IP-to-MAC bindings, which ARP inspection uses to filter out malicious ARP packets." (Page 146, Best Practices Section)

NEW QUESTION # 127
Refer to the exhibit, which shows the current network topology.

You are deploying a new wireless solution with an Aruba Mobility Master (MM). Aruba Mobility Controllers (MCs). and campus APs (CAPs). The solution will Include a WLAN that uses Tunnel for the forwarding mode and Implements WPA3-Enterprise security What is a guideline for setting up the vlan for wireless devices connected to the WLAN?
  • A. Use wireless user roles to assign the devices to a range of new vlan IDs.
  • B. Assign the WLAN to a single new VLAN which is dedicated to wireless users
  • C. Use wireless user roles to assign the devices to different VLANs in the 100-150 range
  • D. Assign the WLAN to a named VLAN which specified 100-150 as the range of IDs.
Answer: C
Explanation:
When setting up VLANs for a wireless solution with an Aruba Mobility Master (MM), Aruba Mobility Controllers (MCs), and campus APs (CAPs), it is recommended to use wireless user roles to assign devices to different VLANs. This allows for greater flexibility and control over network resources and policies applied to different user groups. Wireless user roles can dynamically assign devices to the appropriate VLAN based on a variety of criteria such as user identity, device type, location, and the resources they need to access. This approach aligns with the ArubaOS features that leverage user roles for network access control, as detailed in Aruba's configuration and administration guides.

NEW QUESTION # 128
What is a correct guideline for the management protocols that you should use on ArubaOS-Switches?
  • A. Disable SSH and use https instead.
  • B. Disable HTTPS and use SSH instead
  • C. Disable Telnet and use SSH instead
  • D. Disable Telnet and use TFTP instead.
Answer: A

NEW QUESTION # 129
A client is connected to a Mobility Controller (MC). These firewall rules apply to this client's role:
ipv4 any any svc-dhcp permit
ipv4 user 10.5.5.20 svc-dns permit
ipv4 user 10.1.5.0 255.255.255.0 https permit
ipv4 user 10.1.0.0 255.255.0.0 https deny_opt
ipv4 user any any permit
What correctly describes how the controller treats HTTPS packets to these two IP addresses, both of which are on the other side of the firewall:
10.1.20.1
10.5.5.20
  • A. The first packet is permitted, and the second is denied.
  • B. Both packets are permitted.
  • C. The first packet is denied, and the second is permitted.
  • D. Both packets are denied.
Answer: C
Explanation:
In an HPE Aruba Networking AOS-8 Mobility Controller (MC), firewall rules are applied based on the user role assigned to a client. The rules are evaluated in order, and the first matching rule determines the action (permit or deny) for the packet. The client's role has the following firewall rules:
ipv4 any any svc-dhcp permit: Permits DHCP traffic (UDP ports 67 and 68) from any source to any destination.
ipv4 user 10.5.5.20 svc-dns permit: Permits DNS traffic (UDP port 53) from the user to the IP address 10.5.5.20.
ipv4 user 10.1.5.0 255.255.255.0 https permit: Permits HTTPS traffic (TCP port 443) from the user to the subnet 10.1.5.0/24.
ipv4 user 10.1.0.0 255.255.0.0 https deny_opt: Denies HTTPS traffic from the user to the subnet 10.1.0.0/16, with the deny_opt action (which typically means deny with an optimized action, such as dropping the packet without logging).
ipv4 user any any permit: Permits all other traffic from the user to any destination.
The question asks how the MC treats HTTPS packets (TCP port 443) to two IP addresses: 10.1.20.1 and 10.5.5.20.
HTTPS packet to 10.1.20.1:
Rule 1: Does not match (traffic is HTTPS, not DHCP).
Rule 2: Does not match (destination is 10.1.20.1, not 10.5.5.20; traffic is HTTPS, not DNS).
Rule 3: Does not match (destination 10.1.20.1 is not in the subnet 10.1.5.0/24).
Rule 4: Matches (destination 10.1.20.1 is in the subnet 10.1.0.0/16, and traffic is HTTPS). The action is deny_opt, so the packet is denied.
HTTPS packet to 10.5.5.20:
Rule 1: Does not match (traffic is HTTPS, not DHCP).
Rule 2: Does not match (traffic is HTTPS, not DNS).
Rule 3: Does not match (destination 10.5.5.20 is not in the subnet 10.1.5.0/24).
Rule 4: Does not match (destination 10.5.5.20 is not in the subnet 10.1.0.0/16).
Rule 5: Matches (catches all other traffic). The action is permit, so the packet is permitted.
Therefore, the HTTPS packet to 10.1.20.1 is denied, and the HTTPS packet to 10.5.5.20 is permitted.
Option A, "Both packets are denied," is incorrect because the packet to 10.5.5.20 is permitted.
Option B, "The first packet is permitted, and the second is denied," is incorrect because the packet to 10.1.20.1 (first) is denied, and the packet to 10.5.5.20 (second) is permitted.
Option C, "Both packets are permitted," is incorrect because the packet to 10.1.20.1 is denied.
Option D, "The first packet is denied, and the second is permitted," is correct based on the rule evaluation.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"Firewall policies on the Mobility Controller are evaluated in order, and the first matching rule determines the action for the packet. For example, a rule such as ipv4 user 10.1.0.0 255.255.0.0 https deny_opt will deny HTTPS traffic to the specified subnet, while a subsequent rule like ipv4 user any any permit will permit all other traffic that does not match earlier rules. The 'user' keyword in the rule refers to the client's IP address, and the rules are applied to traffic initiated by the client." (Page 325, Firewall Policies Section) Additionally, the guide notes:
"The deny_opt action in a firewall rule drops the packet without logging, optimizing performance for high-volume traffic. Rules are processed sequentially, and only the first matching rule is applied." (Page 326, Firewall Actions Section)

NEW QUESTION # 130
You have deployed a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs). One of the WLANs enforces 802.1X authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). When you test connecting the client to the WLAN, the test fails. You check ClearPass Access Tracker and cannot find a record of the authentication attempt. You ping from the MC to CPPM, and the ping is successful.
What is a good next step for troubleshooting?
  • A. Check CPPM Event Viewer.
  • B. Reset the user credentials.
  • C. Renew CPPM's RADIUS/EAP certificate.
  • D. Check connectivity between CPPM and a backend directory server.
Answer: A
Explanation:
In this scenario, a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs) are deployed, with a WLAN configured for 802.1X authentication using HPE Aruba Networking ClearPass Policy Manager (CPPM) as the RADIUS server. A client test fails, and no record of the authentication attempt appears in ClearPass Access Tracker. However, a ping from the MC to CPPM is successful, confirming basic network connectivity between the MC and CPPM.
The absence of a record in Access Tracker indicates that CPPM did not receive the RADIUS authentication request from the MC, or the request was rejected at a low level before being logged in Access Tracker. Access Tracker typically logs all RADIUS authentication attempts (successful or failed), so the lack of a record suggests a configuration or connectivity issue at the RADIUS level.
Option C, "Check CPPM Event Viewer," is correct. The CPPM Event Viewer logs system-level events, including RADIUS-related errors that might not appear in Access Tracker. For example, if the MC's IP address is not configured as a Network Access Device (NAD) in CPPM, or if the shared secret between the MC and CPPM does not match, CPPM may reject the RADIUS request before it reaches Access Tracker. The Event Viewer will log such errors (e.g., "RADIUS authentication attempt from unknown NAD"), providing insight into why the request was not processed.
Option A, "Renew CPPM's RADIUS/EAP certificate," is incorrect because the issue is that CPPM did not receive or process the authentication request (no record in Access Tracker). If there were a certificate issue (e.g., an expired or untrusted certificate), the request would still reach CPPM, and Access Tracker would log a failure with a certificate-related error.
Option B, "Check connectivity between CPPM and a backend directory server," is incorrect because the issue occurs before CPPM processes the authentication request. If CPPM cannot contact a backend directory server (e.g., Active Directory), the authentication attempt would still be logged in Access Tracker with a failure reason related to the directory server.
Option D, "Reset the user credentials," is incorrect because the issue is not related to the user's credentials. The authentication request never reached CPPM, so the credentials were not evaluated.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"If an authentication attempt does not appear in Access Tracker, it indicates that the RADIUS request was not received by ClearPass or was rejected at a low level before being logged. The Event Viewer (Monitoring > Event Viewer) should be checked for system-level errors, such as 'RADIUS authentication attempt from unknown NAD' or shared secret mismatches. For example, if the Network Access Device (NAD) IP address of the Mobility Controller is not configured in ClearPass, or if the shared secret does not match, the request will be dropped, and an error will be logged in the Event Viewer." (Page 301, Troubleshooting RADIUS Issues Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
"When troubleshooting 802.1X authentication issues, verify that the Mobility Controller can communicate with the RADIUS server. If a ping is successful but no authentication records appear in the RADIUS server's logs (e.g., ClearPass Access Tracker), check the RADIUS server's system logs (e.g., ClearPass Event Viewer) for errors related to NAD configuration or shared secret mismatches."
