SSH provides encrypted connections between network devices, which is critical for maintaining the security and integrity of network communications. This guideline is aligned with general security best practices that prioritize the use of protocols with strong, built-in encryption mechanisms to prevent unauthorized access and ensure data privacy.
NEW QUESTION # 46
A company has an ArubaOS solution. The company wants to prevent users assigned to the "user_group1" role from using gaming and peer-to-peer applications.
What is the recommended approach for these requirements?
- A. Add access control rules to the "user_group1" role, which deny HTTP/HTTPS traffic to IP addresses associated with gaming and peer-to-peer applications.
- B. Create service aliases for the TCP ports associated with gaming and peer-to-per applications, and use those aliases in access control rules for the "user_group" rules.
- C. Create ALGs for the gaming and peer-to-peer applications, and deny the "user_group1" role on the ALGs.
- D. Make sure DPI is enabled, and add application rules that deny gaming and peer-to-peer applications to the "user_groupr role.
Answer: D
Explanation:
The recommended approach for preventing users in the "user_group1" role from using gaming and peer-to-peer applications in an ArubaOS environment is to enable Deep Packet Inspection (DPI) and add application rules that specifically deny access to these types of applications for the role. DPI allows the network system to analyze the content of network traffic in real time and apply policies based on what it detects, including blocking specific applications like gaming and peer-to-peer sharing. This capability is essential for effectively managing application usage on the network and ensuring compliance with organizational policies. Application-specific rules provide precise control over the network traffic by identifying the application regardless of the network port used, making it a more effective method than blocking based on ports or IP addresses.
NEW QUESTION # 47
What is a benefit or using network aliases in ArubaOS firewall policies?
- A. You can adjust the IP addresses in the aliases, and the rules using those aliases automatically update
- B. You can use the aliases to conceal the true IP addresses of servers from potentially untrusted clients.
- C. You can associate a reputation score with the network alias to create rules that filler traffic based on reputation rather than IP.
- D. You can use the aliases to translate client IP addresses to other IP addresses on the other side of the firewall
Answer: C
NEW QUESTION # 48
What is one benefit of enabling Enhanced Secure mode on an ArubaOS-Switch?
- A. All interfaces have 802.1X authentication enabled on them by default.
- B. Insecure algorithms for protocol such as SSH are automatically disabled.
- C. Control Plane policing rate limits edge ports to mitigate DoS attacks on network servers.
- D. A self-signed certificate is automatically added to the switch trusted platform module (TPM).
Answer: B
Explanation:
In the context of ArubaOS-Switches, enabling Enhanced Secure mode has several benefits, one of which includes disabling insecure algorithms for protocols such as SSH. This is in line with security best practices, as older, less secure algorithms are known to be vulnerable to various types of cryptographic attacks. When Enhanced Secure mode is enabled, the switch automatically restricts the use of such algorithms, thereby enhancing the security of management access.
NEW QUESTION # 49
How does the ArubaOS firewall determine which rules to apply to a specific client's traffic?
- A. The firewall applies every rule that includes the dent's IP address as the source.
- B. The firewall applies thee rules in policies associated with the client's user role.
- C. The firewall applies the rules in policies associated with the client's wlan
- D. The firewall applies every rule that includes the client's IP address as the source or destination.
Answer: B
Explanation:
The ArubaOS firewall determines which rules to apply to a specific client's traffic based on the rules in policies associated with the client's user role. User roles are a fundamental part of ArubaOS and the firewall policies they encompass. These roles contain policies that dictate permissions and restrictions for network traffic. When a client authenticates, it is assigned a role, and the firewall enforces the rules defined within that role for the client's traffic.
References:
ArubaOS firewall and user role configuration guides that explain the role-based access control and firewall policy enforcement.
Industry best practices for network access control that advocate for role-based enforcement mechanisms.
NEW QUESTION # 50 
What is one thing can you determine from the exhibits?
- A. CPPM sent a CoA message to the client to prompt the client to submit information that CPPM can use to profile it.
- B. CPPM was never able to determine a device category for this device, so you need to check settings in the network infrastructure to ensure they support CPPM's endpoint classification.
- C. CPPM originally assigned the client to a role for non-profiled devices. It sent a CoA to the authenticator after it categorized the device.
- D. CPPM first assigned the client to a role based on the user's identity. Then, it discovered that the client had an invalid category, so it sent a CoA to blacklist the client.
Answer: C
Explanation:
Based on the exhibits which seem to show RADIUS authentication and CoA logs, one can determine that CPPM (ClearPass Policy Manager) initially assigned the client to a role meant for non-profiled devices and then sent a CoA to the network access device (authenticator) once the device was categorized. This is a common workflow in network access control, where a device is first given limited access until it can be properly identified, after which appropriate access policies are applied.
NEW QUESTION # 51
What is one practice that can help you to maintain a digital chain or custody In your network?
- A. Ensure that all network Infrastructure devices use RADIUS rather than TACACS+ to authenticate managers
- B. Enable packet capturing on Instant AP or Mobility Controller (MC) control path on an ongoing basis.
- C. Enable packet capturing on Instant AP or Moodily Controller (MC) datepath on an ongoing basis
- D. Ensure that all network infrastructure devices receive a valid clock using authenticated NTP
Answer: D
Explanation:
To maintain a digital chain of custody in a network, a crucial practice is to ensure that all network infrastructure devices receive a valid clock using authenticated Network Time Protocol (NTP). Accurate and synchronized time stamps are essential for creating reliable and legally defensible logs. Authenticated NTP ensures that the time being set on devices is accurate and that the time source is verified, which is necessary for correlating logs from different devices and for forensic analysis.
References:
Digital forensics and network security protocols that underscore the importance of accurate timekeeping for maintaining a digital chain of custody.

NEW QUESTION # 52
What is a Key feature of me ArubaOS firewall?
- A. The firewall Includes application layer gateways (ALGs). which it uses to filter Web traffic based on the reputation of the destination web site.
- B. The firewall examines all traffic at Layer 2 through Layer 4 and uses source IP addresses as the primary way to determine how to control traffic.
- C. The firewall is stateful which means that n can track client sessions and automatically allow return traffic for permitted sessions
- D. The firewall is designed to fitter traffic primarily based on wireless 802.11 headers, making it ideal for mobility environments
Answer: C
Explanation:
The ArubaOS firewall is a stateful firewall, meaning that it can track the state of active sessions and can make decisions based on the context of the traffic. This stateful inspection capability allows it to automatically allow return traffic for sessions that it has permitted, thereby enabling seamless two-way communication for authorized users while maintaining the security posture of the network.References:
ArubaOS firewall documentation.
NEW QUESTION # 53 
An admin has created a WLAN that uses the settings shown in the exhibits (and has not otherwise adjusted the settings in the AAA profile) A client connects to the WLAN Under which circumstances will a client receive the default role assignment?
- A. The client has attempted 802 1X authentication, but failed to maintain a reliable connection, leading to a timeout error
- B. The client has attempted 802 1X authentication, but the MC could not contact the authentication server
- C. The client has passed 802 1X authentication, and the value in the Aruba-User-Role VSA matches a role on the MC
- D. The client has passed 802 1X authentication and the authentication server did not send an Aruba-User-Role VSA
Answer: D
Explanation:
In the context of an Aruba Mobility Controller (MC) configuration, a client will receive the default role assignment if they have passed 802.1X authentication and the authentication server did not send an Aruba-User-Role Vendor Specific Attribute (VSA). The default role is assigned by the MC when a client successfully authenticates but the authentication server provides no specific role instruction. This behavior ensures that a client is not left without any role assignment, which could potentially lead to a lack of network access or access control. This default role assignment mechanism is part of Aruba's role-based access control, as documented in the ArubaOS user guide and best practices.

- A. There is no need to locate the AP If the Aruba solution is properly configured to automatically contain it.
- B. There is no need to locale the AP If you manually contain It.
- C. For forensic purposes, you should copy out logs with relevant information, such as the time mat the AP was detected and the AP's MAC address.
- D. This is a serious security event, so you should always contain the AP immediately regardless of your company's specific policies.
- E. You should receive permission before containing an AP. as this action could have legal Implications.
Answer: C,E
Explanation:
When responding to the detection of a Rogue AP, it's important to consider legal implications and to gather forensic evidence:
You should receive permission before containing an AP (Option C), as containing it could disrupt service and may have legal implications, especially if the AP is on a network that the organization does not own.
For forensic purposes, it is essential to document the event by copying out logs with relevant information, such as the time the AP was detected and the AP's MAC address (Option D). This information could be crucial if legal action is taken or if a detailed analysis of the security breach is required.
Automatically containing an AP without consideration for the context (Options A and E) can be problematic, as it might inadvertently interfere with neighboring networks and cause legal issues. Immediate containment without consideration of company policy (Option B) could also violate established incident response procedures.

How can hackers implement a man-in-the-middle (MITM) attack against a wireless client?
- A. The hacker uses a combination of software and hardware to jam the RF band and prevent the client from connecting to any wireless networks.
- B. The hacker uses spear-phishing to probe for the IP addresses that the client is attempting to reach. The hacker device then spoofs those IP addresses.
- C. The hacker runs an NMap scan on the wireless client to find its MAC and IP address. The hacker then connects to another network and spoofs those addresses.
- D. The hacker connects a device to the same wireless network as the client and responds to the client's ARP requests with the hacker device's MAC address.
Answer: D
Explanation:
A common method for hackers to perform a man-in-the-middle (MITM) attack on a wireless network is by ARP poisoning. The attacker connects to the same network as the victim and sends false ARP messages over the network. This causes the victim's device to send traffic to the attacker's machine instead of the legitimate destination, allowing the attacker to intercept the traffic.
