HP Aruba Certified Network Security Associate Exam Sample Questions (Q159-Q164):

NEW QUESTION # 159
A user is having trouble connecting to an AP managed by a standalone Mobility Controller (MC). What can you do to get detailed logs and debugs for that user's client?

  • A. In the MC CLI, set up a data plane packet capture and filter for the client's MAC address.
  • B. In the MC CLI, set up a control plane packet capture and filter for the client's IP address.
  • C. In the MC UI's Diagnostics > Logs pages, add a "user-debug" log setting for the client's MAC address.
  • D. In the MC UI's Traffic Analytics dashboard, look for the client's IP address.

Answer: C

Explanation:
When troubleshooting connectivity issues for a user connecting to an AP managed by a standalone Mobility Controller (MC) in an AOS-8 architecture, detailed logs and debugs specific to the user's client are essential. The MC provides several tools for capturing logs and debugging information, including packet captures and user-specific debug logs.
Option D, "In the MC UI's Diagnostics > Logs pages, add a 'user-debug' log setting for the client's MAC address," is correct. The "user-debug" feature in the MC allows administrators to enable detailed debugging for a specific client by specifying the client's MAC address. This generates logs related to the client's authentication, association, role assignment, and other activities, which are critical for troubleshooting connectivity issues. The Diagnostics > Logs pages in the MC UI provide a user-friendly way to configure this setting and view the resulting logs.
Option A, "In the MC CLI, set up a control plane packet capture and filter for the client's IP address," is incorrect because control plane packet captures are used to capture management traffic (e.g., between the MC and APs or other controllers), not user traffic. Additionally, the client may not yet have an IP address if connectivity is failing, making an IP-based filter less effective.
Option B, "In the MC CLI, set up a data plane packet capture and filter for the client's MAC address," is a valid troubleshooting method but is not the best choice for getting detailed logs. Data plane packet captures are useful for analyzing user traffic (e.g., to see if packets are being dropped), but they do not provide the same level of detailed logging as the "user-debug" feature, which includes authentication and association events.
Option C, "In the MC UI's Traffic Analytics dashboard, look for the client's IP address," is incorrect because the Traffic Analytics dashboard is used for monitoring application usage and traffic patterns, not for detailed troubleshooting of a specific client's connectivity issues. Additionally, if the client cannot connect, it may not have an IP address or generate traffic visible in the dashboard.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"To troubleshoot issues for a specific wireless client, you can enable user-specific debugging using the 'user-debug' feature. In the Mobility Controller UI, navigate to Diagnostics > Logs, and add a 'user-debug' log setting for the client's MAC address. This will generate detailed logs for the client, including authentication, association, and role assignment events, which can be viewed in the Logs page. For example, to enable user-debug for a client with MAC address 00:11:22:33:44:55, add the setting 'user-debug 00:11:22:33:44:55'." (Page 512, Troubleshooting Wireless Clients Section) Additionally, the guide notes:
"While packet captures (control plane or data plane) can be useful for analyzing traffic, the 'user-debug' feature provides more detailed logs for troubleshooting client-specific issues, such as failed authentication or association problems." (Page 513, Debugging Tools Section)

NEW QUESTION # 160
The first exhibit shows roles on the MC, listed in alphabetic order. The second and third exhibits show the configuration for a WLAN to which a client connects. Which description of the role assigned to a user under various circumstances is correct?

  • A. A user fails 802.1X authentication. The client remains connected, but is assigned the "guest" role.
  • B. A user authenticates successfully with 802.1 X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employeel." The client's role is "guest."
  • C. A user authenticates successfully with 802.1X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employee." The client's role is "guest."
  • D. A user authenticates successfully with 802.1X, and the RADIUS Access-Accept includes an Aruba-User-RoleVSA set to "employeel." The client's role is "employeel."

Answer: D

Explanation:
In a WLAN setup that uses 802.1X for authentication, the role assigned to a user is determined by the result of the authentication process. When a user successfully authenticates via 802.1X, the RADIUS server may include a Vendor-Specific Attribute (VSA), such as the Aruba-User-Role, in the Access-Accept message.
This attribute specifies the role that should be assigned to the user. If the RADIUS Access-Accept message includes an Aruba-User-Role VSA set to "employee1", the client should be assigned the "employee1" role, as per the VSA, and not the default "guest" role. The "guest" role would typically be a fallback if no other role is specified or if the authentication fails.


NEW QUESTION # 161
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 WPA3-Enterprise for the security option.
You have decided to assign the WLAN to VLAN 301, a new VLAN. A pair of core routing switches will act as the default router for wireless user traffic.
Which links need to carry VLAN 301?

  • A. only links in the campus LAN to ensure seamless roaming
  • B. only links on the path between APs and the MC
  • C. only links on the path between APs and the core routing switches
  • D. only links between MC ports and the core routing switches

Answer: D

Explanation:
In a wireless network deployment with Aruba Mobility Master (MM), Mobility Controllers (MCs), and Campus APs (CAPs), where a WLAN is configured to use Tunnel mode for forwarding, the user traffic is tunneled from the APs to the MCs. VLAN 301, which is assigned to the WLAN, must be present on the links from the MCs to the core routing switches because these switches act as the default router for the wireless user traffic. It is not necessary for the VLAN to be present on all campus LAN links or AP links, only between the MCs and the core routing switches where the routing for VLAN 301 will occur.


NEW QUESTION # 162
What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial of Service (DoS) attack?

  • A. A DDoS attack originates from external devices, while a DoS attack originates from internal devices.
  • B. A DoS attack targets one server; a DDoS attack targets all the clients that use a server.
  • C. A DDoS attack is launched from multiple devices, while a DoS attack is launched from a single device.
  • D. A DDoS attack targets multiple devices, while a DoS is designed to incapacitate only one device.

Answer: C

Explanation:
Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are both designed to disrupt the availability of a network, service, or device by overwhelming it with traffic or requests. HPE Aruba Networking documentation, particularly in the context of Wireless Intrusion Prevention (WIP) and network security, often discusses these attacks to help administrators mitigate them.
DoS Attack: A DoS attack is launched from a single source (e.g., one device or IP address) and aims to overwhelm a target (e.g., a server, network, or device) with traffic, making it unavailable to legitimate users. For example, a DoS attack might flood a server with SYN packets to exhaust its resources.
DDoS Attack: A DDoS attack is a more sophisticated version of a DoS attack, where the attack is launched from multiple sources (e.g., a botnet of compromised devices). These sources work together to overwhelm the target, making the attack harder to mitigate because the traffic comes from many different IP addresses.
Option A, "A DDoS attack originates from external devices, while a DoS attack originates from internal devices," is incorrect. Both DoS and DDoS attacks can originate from external or internal devices. The distinction is not about the location of the devices but the number of sources involved.
Option B, "A DoS attack targets one server; a DDoS attack targets all the clients that use a server," is incorrect. Both DoS and DDoS attacks typically target a single entity (e.g., a server, network, or device) to disrupt its availability. They do not target "all the clients that use a server." Option C, "A DDoS attack targets multiple devices, while a DoS is designed to incapacitate only one device," is incorrect. Both DoS and DDoS attacks usually target a single device or service to overwhelm it. The difference lies in the source of the attack, not the number of targets.
Option D, "A DDoS attack is launched from multiple devices, while a DoS attack is launched from a single device," is correct. This is the primary distinction between the two: a DDoS attack involves multiple sources (e.g., a botnet), while a DoS attack originates from a single source.
The HPE Aruba Networking Security Guide states:
"A Denial of Service (DoS) attack is launched from a single device to overwhelm a target, such as a server or network, making it unavailable to legitimate users. A Distributed Denial of Service (DDoS) attack, in contrast, is launched from multiple devices, often a botnet of compromised systems, to flood the target with traffic from many sources, making it harder to mitigate." (Page 20, DoS and DDoS Attacks Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
"The Wireless Intrusion Prevention (WIP) system can detect DoS and DDoS attacks. A DoS attack originates from a single source, while a DDoS attack involves multiple sources working together to overwhelm the target, such as a server or network infrastructure." (Page 423, WIP Threat Detection Section)

NEW QUESTION # 163
What is one way that WPA3-Enterprise enhances security when compared to WPA2-Enterprise?

  • A. WPA3-Enterprise uses Diffie-Hellman in order to authenticate clients, while WPA2-Enterprise uses 802.1X authentication.
  • B. WPA3-Enterprise implements the more secure simultaneous authentication of equals (SAE), while WPA2-Enterprise uses 802.1X.
  • C. WPA3-Enterprise can operate in CNSA mode, which mandates that the 802.11 association uses secure algorithms.
  • D. WPA3-Enterprise provides built-in mechanisms that can deploy user certificates to authorized end-user devices.

Answer: C

Explanation:
WPA3-Enterprise enhances network security over WPA2-Enterprise through several improvements, one of which is the ability to operate in CNSA (Commercial National Security Algorithm) mode. This mode mandates the use of secure cryptographic algorithms during the 802.11 association process, ensuring that all communications are highly secure. The CNSA suite provides stronger encryption standards designed to protect sensitive government, military, and industrial communications. Unlike WPA2, WPA3's CNSA mode uses stronger cryptographic primitives, such as AES-256 in Galois/Counter Mode (GCM) for encryption and SHA-384 for hashing, which are not standard in WPA2-Enterprise.
