HP Aruba Certified Network Security Associate Exam Sample Questions (Q88-Q93):

NEW QUESTION # 88
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. Assign the WLAN to a named VLAN which specified 100-150 as the range of IDs.
• B. Use wireless user roles to assign the devices to different VLANs in the 100-150 range
• C. Assign the WLAN to a single new VLAN which is dedicated to wireless users
• D. Use wireless user roles to assign the devices to a range of new vlan IDs.

Answer: B

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 # 89
Your HPE Aruba Networking Mobility Master-based solution has detected a rogue AP. Among other information, the AOS Detected Radios page lists this information for the AP:
SSID = PublicWiFi
BSSID = a8:bd:27:12:34:56
Match method = Plus one
Match method = Eth-Wired-Mac-Table
The security team asks you to explain why this AP is classified as a rogue. What should you explain?

• A. The AP is an AP that belongs to your solution. However, the AOS has detected that it is behaving suspiciously. It might have been compromised, so it is classified as a suspected rogue.
• B. The AP has a BSSID that is close to your authorized APs' BSSIDs. This indicates that the AP might be spoofing the corporate SSID and attempting to lure clients to it, making the AP a suspected rogue.
• C. The AP is probably connected to your LAN because it has a BSSID that is close to a MAC address that has been detected in your LAN. Because it does not belong to the company, it is a suspected rogue.
• D. The AP has been detected using multiple MAC addresses. This indicates that the AP is spoofing its MAC address, which qualifies it as a suspected rogue.

Answer: C

Explanation:
HPE Aruba Networking's Wireless Intrusion Prevention (WIP) system, part of the AOS-8 architecture (Mobility Master and Mobility Controllers), is designed to detect and classify rogue APs. The "AOS Detected Radios" page provides details about detected APs, including their SSID, BSSID, and match methods used to classify them.
In this case, the AP is classified as a rogue with the following match methods:
Plus one: This indicates that the BSSID of the detected AP is numerically close (e.g., differs by one in the last octet) to the MAC address of a known device in the network.
Eth-Wired-Mac-Table: This indicates that the AP's MAC address (or a closely related MAC address) was found in the wired network's MAC address table, suggesting that the AP is connected to the LAN.
These match methods suggest that the AP is likely connected to the company's wired LAN (via the Eth-Wired-Mac-Table match) and has a BSSID that is close to a known device's MAC address (Plus one match). Since this AP is not part of the company's authorized AP list (it's broadcasting "PublicWiFi," which may not be a corporate SSID), it is classified as a suspected rogue. This scenario is common when an unauthorized AP is plugged into the corporate LAN, posing a security risk.
Option A, "The AP has been detected using multiple MAC addresses," is incorrect because the match methods do not indicate multiple MAC addresses; they indicate a close match to a known MAC and a presence in the wired MAC table.
Option C, "The AP is an AP that belongs to your solution," is incorrect because the AP is classified as a rogue, meaning it is not part of the authorized APs in the solution.
Option D, "The AP has a BSSID that is close to your authorized APs' BSSIDs," is partially correct in that the "Plus one" match indicates a close BSSID, but the key reason for the rogue classification is its connection to the LAN (Eth-Wired-Mac-Table), not just the BSSID similarity.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"The Wireless Intrusion Prevention (WIP) system detects rogue APs by analyzing their BSSIDs, SSIDs, and connectivity to the wired network. The 'Eth-Wired-Mac-Table' match method indicates that the AP's MAC address (or a closely related address) was found in the wired network's MAC address table, suggesting that the AP is connected to the LAN. The 'Plus one' match method indicates that the AP's BSSID is numerically close to a known MAC address in the network, which can indicate a potential rogue device attempting to mimic a legitimate device." (Page 412, Rogue AP Detection Section) Additionally, the guide notes:
"A rogue AP is classified as 'suspected rogue' if it is detected on the wired network (e.g., via Eth-Wired-Mac-Table) and is not part of the authorized AP list. This often occurs when an unauthorized AP is connected to the corporate LAN." (Page 413, Rogue AP Classification Section)

NEW QUESTION # 90
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 connectivity between CPPM and a backend directory server.
• B. Check CPPM Event Viewer.
• C. Renew CPPM's RADIUS/EAP certificate.
• D. Reset the user credentials.

Answer: B

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."

NEW QUESTION # 91
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 denied, and the second is permitted.
• B. The first packet is permitted, and the second is denied.
• C. Both packets are denied.
• D. Both packets are permitted.

Answer: A

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 # 92
What is social engineering?

• A. Hackers use employees to circumvent network security and gather the information they need to launch an attack.
• B. Hackers use Artificial Intelligence (Al) to mimic a user's online behavior so they can infiltrate a network and launch an attack.
• C. Hackers intercept traffic between two users, eavesdrop on their messages, and pretend to be one or both users.
• D. Hackers spoof the source IP address in their communications so they appear to be a legitimate user.

Answer: A

Explanation:
Social engineering in the context of network security refers to the techniques used by hackers to manipulate individuals into breaking normal security procedures and best practices to gain unauthorized access to systems, networks, or physical locations, or for financial gain. Hackers use various forms of deception to trick employees into handing over confidential or personal information that can be used for fraudulent purposes. This definition encompasses phishing attacks, pretexting, baiting, and other manipulative techniques designed to exploit human psychology. Unlike other hacking methods that rely on technical means, social engineering targets the human element of security. to social engineering, its methods, and defense strategies are commonly found in security training manuals, cybersecurity awareness programs, and authoritative resources like those from the SANS Institute or cybersecurity agencies.
