質問 # 106
A company with 465 employees wants to deploy an open WLAN for guests. The company wants the experience to be as follows:
Guests select the WLAN and connect without having to enter a password.
Guests are redirected to a welcome web page and log in.
The company also wants to provide encryption for the network for devices that are capable. Which security options should you implement for the WLAN?
正解：C
解説：
The company wants to deploy an open WLAN for guests with the following requirements:
Guests connect without entering a password (open authentication).
Guests are redirected to a welcome web page and log in (captive portal).
Encryption is provided for devices that support it.
Open WLAN with Captive Portal: An open WLAN means no pre-shared key (PSK) or 802.1X authentication is required to connect. A captive portal can be used to redirect users to a web page where they must log in (e.g., with guest credentials). This meets the requirement for guests to connect without a password and then log in via a web page.
Encryption for Capable Devices: The company wants to provide encryption for devices that support it, even on an open WLAN. Opportunistic Wireless Encryption (OWE) is a WPA3 feature designed for open networks. OWE provides encryption without requiring a password by negotiating unique encryption keys for each client using a Diffie-Hellman key exchange. OWE in transition mode allows both OWE-capable devices (which use encryption) and non-OWE devices (which connect without encryption) to join the same SSID, ensuring compatibility.
Option A, "Opportunistic Wireless Encryption (OWE) and WPA3-Personal," is incorrect. WPA3-Personal requires a pre-shared key (password), which conflicts with the requirement for guests to connect without entering a password.
Option B, "Captive portal and WPA3-Personal," is incorrect for the same reason. WPA3-Personal requires a password, which does not meet the open WLAN requirement.
Option C, "WPA3-Personal and MAC-Auth," is incorrect. WPA3-Personal requires a password, and MAC authentication (MAC-Auth) does not provide the web-based login experience (captive portal) specified in the requirements.
Option D, "Captive portal and Opportunistic Wireless Encryption (OWE) in transition mode," is correct. An open WLAN with OWE in transition mode allows guests to connect without a password, provides encryption for OWE-capable devices (e.g., WPA3 devices), and supports non-OWE devices without encryption. The captive portal ensures that guests are redirected to a welcome web page to log in, meeting all requirements.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"Opportunistic Wireless Encryption (OWE) is a WPA3 feature that provides encryption for open WLANs without requiring a password. In OWE transition mode, the WLAN supports both OWE-capable devices (which use encryption) and non-OWE devices (which connect without encryption) on the same SSID. This is ideal for guest networks where encryption is desired for capable devices, but compatibility with all devices is required. A captive portal can be configured on an open WLAN to redirect users to a login page, such as captive-portal guest-login, ensuring a seamless guest experience." (Page 290, OWE and Captive Portal Section) Additionally, the HPE Aruba Networking Wireless Security Guide notes:
"OWE in transition mode is recommended for open guest WLANs where encryption is desired for devices that support it. Combined with a captive portal, this setup allows guests to connect without a password, get redirected to a login page, and benefit from encryption if their device supports OWE." (Page 35, Guest Network Security Section)

質問 # 107
What is an example of passive endpoint classification?
正解：A
解説：
Endpoint classification in HPE Aruba Networking ClearPass Policy Manager (CPPM) involves identifying and categorizing devices on the network to enforce access policies. CPPM supports two types of profiling methods: passive and active.
Passive Profiling: Involves observing network traffic that devices send as part of their normal operation, without CPPM sending any requests to the device. Examples include DHCP fingerprinting, HTTP User-Agent analysis, and TCP fingerprinting.
Active Profiling: Involves CPPM sending requests to the device to gather information, such as SNMP scans, WMI scans, or SSH probes.
Option A, "TCP fingerprinting," is correct. TCP fingerprinting is a passive profiling method where CPPM analyzes TCP packet headers (e.g., TTL, window size) in the device's normal network traffic to identify its operating system. This does not require CPPM to send any requests to the device, making it a passive method.
Option B, "SSH scans," is incorrect. SSH scans involve actively connecting to a device over SSH to gather information (e.g., system details), which is an active profiling method.
Option C, "WMI scans," is incorrect. Windows Management Instrumentation (WMI) scans involve CPPM querying a Windows device to gather information (e.g., OS version, installed software), which is an active profiling method.
Option D, "SNMP scans," is incorrect. SNMP scans involve CPPM sending SNMP requests to a device to gather information (e.g., system description, interfaces), which is an active profiling method.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"Passive profiling methods observe network traffic that endpoints send as part of their normal operation, without ClearPass sending any requests to the device. An example of passive profiling is TCP fingerprinting, where ClearPass analyzes TCP packet headers (e.g., TTL, window size) to identify the device's operating system. Active profiling methods, such as SNMP scans, WMI scans, or SSH scans, involve ClearPass sending requests to the device to gather information." (Page 246, Passive vs. Active Profiling Section) Additionally, the ClearPass Device Insight Data Sheet notes:
"Passive profiling techniques, such as TCP fingerprinting, allow ClearPass to identify devices without generating additional network traffic. By analyzing TCP attributes in the device's normal traffic, ClearPass can fingerprint the OS, making it a non-intrusive method for endpoint classification." (Page 3, Profiling Methods Section)

質問 # 108
You have been instructed to look in the ArubaOS Security Dashboard's client list Your goal is to find clients mat belong to the company and have connected to devices that might belong to hackers Which client fits this description?
正解：A
質問 # 109
Which correctly describes one of HPE Aruba Networking ClearPass Policy Manager's (CPPM's) device profiling methods?
正解：A
解説：
HPE Aruba Networking ClearPass Policy Manager (CPPM) uses device profiling to identify and classify endpoints on the network, enabling granular access control based on device type, OS, or other attributes. CPPM supports both passive and active profiling methods.
Option C, "CPPM can analyze settings such as TTL and time window size in endpoints' TCP traffic in order to fingerprint the OS," is correct. TCP fingerprinting is a passive profiling method used by CPPM. It involves analyzing TCP packet headers, such as the Time To Live (TTL) value and TCP window size, which vary between operating systems (e.g., Windows, Linux, macOS). CPPM captures this traffic (e.g., via mirrored traffic from a switch or controller) and matches the TCP attributes against its fingerprint database to identify the OS of the endpoint.
Option A, "CPPM can use Wireshark to actively probe devices, analyze their traffic patterns, and construct an endpoint profile," is incorrect. CPPM does not use Wireshark for profiling; Wireshark is a third-party packet analysis tool. CPPM has its own built-in profiling engine and does not rely on external tools like Wireshark for active probing.
Option B, "CPPM can use SNMP to configure Aruba switches and mobility devices to mirror client traffic to CPPM for analysis," is incorrect. While CPPM can receive mirrored traffic for profiling (e.g., via SPAN or mirror ports), it does not use SNMP to configure the mirroring. The configuration of traffic mirroring is typically done manually on the switch or controller (e.g., using a datapath mirror on an MC), not via SNMP by CPPM.
Option D, "CPPM can analyze settings such as TCP/UDP ports used for HTTP, DHCP, and DNS in endpoints' traffic to fingerprint the OS," is incorrect. While CPPM does analyze HTTP, DHCP, and DNS traffic for profiling, it does not fingerprint the OS based on TCP/UDP ports. Instead, it uses attributes like DHCP Option 55 (for DHCP fingerprinting) or HTTP User-Agent strings (for HTTP fingerprinting) to identify devices, not the ports themselves.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"ClearPass supports TCP fingerprinting as a passive profiling method to identify the operating system of endpoints. By analyzing TCP packet headers, such as the Time To Live (TTL) value and TCP window size, ClearPass can fingerprint the OS of a device. For example, Windows devices typically have a TTL of 128, while Linux devices often have a TTL of 64. These attributes are matched against ClearPass's fingerprint database to classify the device." (Page 248, TCP Fingerprinting Section) Additionally, the ClearPass Device Insight Data Sheet notes:
"ClearPass uses passive profiling techniques like TCP fingerprinting to identify device operating systems. By examining TCP attributes such as TTL and window size, ClearPass can accurately determine whether a device is running Windows, Linux, macOS, or another OS, enabling precise policy enforcement."

質問 # 110
What is a reason to set up a packet capture on an HPE Aruba Networking Mobility Controller (MC)?
正解：B
解説：
Packet captures on an HPE Aruba Networking Mobility Controller (MC) are a powerful troubleshooting and analysis tool, allowing administrators to capture and analyze network traffic at various levels (e.g., control plane or data plane). The MC supports packet captures for both wired and wireless traffic, which can be filtered based on criteria such as IP address, MAC address, or port.
Option A, "The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely," is correct. Packet captures are commonly used in security investigations to analyze the traffic of a specific endpoint suspected of malicious activity. For example, if a wireless client is suspected of launching an attack (e.g., a DoS attack or data exfiltration), a packet capture on the MC can capture the client's traffic (filtered by MAC or IP address) for detailed analysis, helping the security team identify the nature of the attack.
Option B, "The company wants to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC," is incorrect. While CPPM can use HTTP User-Agent strings for device profiling, this is typically achieved by mirroring HTTP traffic to CPPM (e.g., using a datapath mirror on the MC), not by setting up a packet capture. Packet captures are for manual analysis, not for feeding data to CPPM.
Option C, "You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control Web traffic based on the destination URL," is incorrect. The AOS firewall on the MC can control traffic based on applications or services (e.g., using deep packet inspection, DPI), but it does not support URL-based filtering directly. URL filtering typically requires an external solution (e.g., a web proxy or firewall). Packet captures are not used to enable URL-based control by the firewall.
Option D, "You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control the traffic based on application," is incorrect. The AOS firewall can already perform application-based control using DPI (if enabled), without requiring a packet capture. Packet captures are for manual analysis, not for enabling firewall functionality.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"Packet captures on the Mobility Controller are useful for troubleshooting and security investigations. For example, if the security team suspects that a wireless endpoint is launching an attack, you can set up a packet capture on the MC's data plane to capture the endpoint's traffic. Use the command packet-capture datapath <filter> (e.g., filter by the client's MAC address) to capture the traffic, which can then be analyzed to identify malicious activity." (Page 515, Packet Capture Section) Additionally, the HPE Aruba Networking Security Guide notes:
"Packet captures are a critical tool for security teams to investigate potential attacks. By capturing traffic from a specific wireless client suspected of malicious behavior, administrators can analyze the packets to determine the nature of the attack, such as a DoS attack or unauthorized data exfiltration."
