HPE6-A78 Exam Questions
- HP Aruba Certifications
- HP Aruba Certified Network Security Associate ACNSA Certifications
- Topic 1: Protect and Defend: This section of the exam measures the skills of a Network Security Engineer and covers foundational and advanced concepts related to securing a network environment. Candidates are expected to understand common security threats such as man-in-the-middle attacks, DDoS, spoofing, and zero-day vulnerabilities, as well as distinguish between threats and vulnerabilities. It evaluates knowledge of security protocols, PKI components, and firewall mechanisms like PEF and AppRF. It also explores user roles, policy enforcement, and secure management protocols such as SSH and HTTPS.
- Topic 2: Analyze: This section of the exam evaluates the capabilities of a Cybersecurity Analyst and focuses on analyzing network activity and security alerts to identify potential threats. The candidate must demonstrate an understanding of wireless intrusion prevention and detection systems (WIPS/WIDS), interpreting alarms, and recognizing attack stages through the kill chain model. Skills in collecting system logs, reviewing access tracker information, and examining historical network pattern data are essential. The ability to identify and evaluate endpoints discovered on the network is also included in this analytical domain.
- Topic 3: Investigate: This section of the exam assesses the investigative abilities of a Cybersecurity Analyst and centers around proper methods for conducting investigations after a security incident. Candidates are required to know how to collect logs for evidence, understand the principles of maintaining a chain of custody, and initiate an investigation using structured procedures. This domain emphasizes the importance of data integrity, documentation, and analysis during the post-incident process to ensure accurate and reliable outcomes.

A company has a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise security, supported by an Aruba Mobility Controller (MC) and campus APs (CAPs). You have been asked to capture packets from a wireless client connected to this WLAN and submit the packets to the security team.
What is a guideline for this capture?
The correct approach for capturing packets from a wireless client in a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise, managed by an Aruba Mobility Controller and Campus APs, is to use an Air Monitor (AM). An AM is specifically designed to capture wireless traffic 'in the air,' which means it listens to the wireless signals transmitted between devices and the access points. This method ensures that the capture includes all the necessary details while maintaining the integrity and security of the data as it is transmitted over the air. Using an Air Monitor helps in analyzing the raw wireless traffic before it gets encrypted or tunneled to the Mobility Controller, providing a clear view of the wireless client's activity and interactions. The information regarding the use of Air Monitors for packet capture in such environments can be found in the Aruba Network's official documentation and configuration guides for WLAN setups and security analysis.
A company has Aruba Mobility Controllers (MCs), Aruba campus APs, and ArubaOS-CX switches. The company plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type. The company is contemplating the use of ClearPass's TCP fingerprinting capabilities.
What is a consideration for using those capabilities?
ClearPass Policy Manager (CPPM) uses various methods to classify endpoints, and one of them is TCP fingerprinting, which involves analyzing TCP/IP packets to identify the type of device or operating system sending them. To utilize TCP fingerprinting capabilities, network traffic needs to be accessible to the CPPM. This can be done by mirroring traffic to CPPM's span port from a device that can see the traffic, like a core routing switch. This approach allows CPPM to observe the TCP characteristics of devices as they communicate over the network, enabling it to make more accurate decisions for device classification.
Device A is contacting https://arubapedia.arubanetworks.com. The web server sends a certificate chain. What does the browser do as part of validating the web server certificate?
When a device like Device A contacts a secure website and receives a certificate chain from the server, the browser's primary task is to validate the web server's certificate to ensure it is trustworthy. Part of this validation includes checking that the certificate contains a DNS Subject Alternative Name (SAN) that matches the domain name of the website being accessed---in this case, arubapedia.arubanetworks.com. This ensures that the certificate was indeed issued to the entity operating the domain and helps prevent man-in-the-middle attacks where an invalid certificate could be presented by an attacker. The DNS SAN check is critical because it directly ties the digital certificate to the domain it secures, confirming the authenticity of the website to the user's browser.
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?
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.
What is a consideration for implementing wireless containment in response to unauthorized devices discovered by ArubaOS Wireless Intrusion Detection (WIP)?
When implementing wireless containment as a response to unauthorized devices, a company should consider the legal implications. Wireless containment might affect devices that are not part of the company's network and could be considered as a form of interference. This could have legal consequences, and therefore, such actions should be carefully reviewed and ideally should be performed in a targeted and controlled manner, reducing the risk of legal issues.
