• Question 11:

  You are helping an organization deploy HPE Aruba Networking SSE. What is one reason to recommend that the company install agents on remote users' devices?

  A. To run posture checks and apply different permissions based on those checks.
  B. To permit admins to manage the HPE Aruba Networking SSE policy rules.
  C. To permit users to access private servers using SSH.
  D. To run threat inspection on clients in a local sandbox rather than in the cloud.
  A. To run posture checks and apply different permissions based on those checks.

  ---

  Explanation

  Installing Agents for SSE (Secure Service Edge):

  Agents installed on remote users' devices allow

  posture checks (e.g., antivirus status, OS

  version) to ensure compliance.

  Based on the results of the posture checks, different permissions and security policies can be applied dynamically.

  This improves the security posture of remote users before granting access to resources.

  Option A: Correct. Agents enable posture checks and enforce conditional access based on compliance.

  Option B: Incorrect. Admins manage SSE policies centrally, not via agents.

  Option C: Incorrect. Access to private servers via SSH does not require agents; it relies on policies and tunnels.

  Option D: Incorrect. Local sandboxing is generally a function of endpoint protection solutions,

• Question 12:

  A company is using HPE Aruba Networking Central SD-WAN Orchestrator to establish a hub-spoke VPN between branch gateways (BGWs) at 1164 site and VPNCs at multiple data centers. What is part of the configuration that admins need to complete?

  A. In VPNCs' groups, establish VPN pools to control which branches connect to which VPNCs.
  B. In BGWs' and VPNCs' groups, create default IKE policies for the SD-WAN Orchestrator to use.
  C. In BGWs' groups, select the VPNCs to which to connect in a DC preference list.
  D. At the global level, create default IPsec policies for the SD-WAN Orchestrator to use.
  C. In BGWs' groups, select the VPNCs to which to connect in a DC preference list.

  ---

  Explanation

  Hub-Spoke VPN Configuration:

  HPE Aruba Central SD-WAN Orchestrator enables hub-spoke topology where branch gateways (BGWs) connect to VPN concentrators (VPNCs) located at data centers.

  A key step in configuring this is defining which VPNCs the BGWs will prefer for connectivity.

  The DC Preference List is configured in the BGW groups to prioritize the data centers to which BGWs connect.

  Option Analysis:

  Option A: Incorrect. VPN pools control IP allocation, not which branches connect to VPNCs.

  Option B: Incorrect. IKE policies define key exchange mechanisms but are not part of the connection preference process.

  Option C: Correct. Admins configure a DC preference list in BGW groups to determine connectivity priorities with VPNCs.

  Option D: Incorrect. IPsec policies define encryption parameters at a global level, but this is not specific to the hub-spoke connection configuration.

• Question 13:

  HPE Aruba Networking Central displays an alert about an Infrastructure Attack that was detected. You go to the Security > RAPIDS events and see that the attack was "Detect adhoc using Valid SSID." What is one possible next step?

  A. Make sure that you have tuned the threshold for that check as false positives are common for it.
  B. Make sure that clients have updated drivers, as faulty drivers are a common explanation for this attack type.
  C. Use HPE Aruba Networking Central floorplans or the detecting AP identities to locate the general area for the threat.
  D. Look for the IP address associated with the offender and then check for that IP address among HPE Aruba Networking Central clients.
  C. Use HPE Aruba Networking Central floorplans or the detecting AP identities to locate the general area for the threat.

  ---

  Explanation

  RAPIDS Ad-Hoc Detection:

  The alert "Detect ad-hoc using Valid SSID" indicates that a device is broadcasting an SSID that matches a valid network SSID in ad-hoc mode . This can be an indication of an infrastructure attack or misconfiguration.

  Next Steps:

  Use Aruba Central floorplans or AP location data to identify the physical area where the offending device is detected.

  Locate and investigate the device to determine if it is malicious or simply misconfigured.

  Option Analysis:

  Option A: Incorrect. While tuning thresholds is useful for reducing false positives, this step does not directly address a potential threat.

  Option B: Incorrect. Faulty drivers can cause similar behavior, but this step is not immediately actionable without locating the device first.

  Option C: Correct. Floorplans or AP identities help locate the threat's physical area for further investigation.

  Option D: Incorrect. RAPIDS focuses on detecting devices via SSID and MAC, not IP addresses, making this approach less relevant.

• Question 14:

  A company already uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as the RADIUS server for authenticating wireless clients with 802.1X. Now you are setting up 802.1X on AOS-CX switches to authenticate many of those same clients on wired connections. You decide to copy CPPM's wireless 802.1X service and then edit it with a new name and enforcement policy. What else must you change for authentication to work properly?

  A. Role mapping policy
  B. Authentication methods
  C. Authentication source
  D. Service rules
  D. Service rules

  ---

  Explanation

  802.1X Service Rules:

  Service rules define the criteria for when a specific service applies (e.g., wireless vs. wired authentication).

  For wired 802.1X authentication to work properly, the service rules need to differentiate between wireless and wired connections.

  If you copy the wireless service, the rules likely still match wireless-specific criteria. These must be updated to include wired-specific conditions (e.g., NAS IP or port types).

  Option Analysis:

  Option A (Role mapping policy): Role mapping policies determine user roles based on attributes but are not critical for differentiating wired vs. wireless.

  Option B (Authentication methods): Authentication methods (e.g., EAP) remain the same for both wireless and wired 802.1X.

  Option C (Authentication source): Authentication sources (like AD or internal database) do not need to change.

  Option D (Service rules): Correct. Updating the service rules ensures the new 802.1X service

• Question 15:

  A company has a third-party security appliance deployed in its data center. The company wants to pass all traffic for certain clients through that device before forwarding that traffic toward its ultimate destination.

  Which AOS-CX switch technology fulfills this use case?

  A. Virtual Network Based Tunneling (VNBT)
  B. MC-LAG
  C. Network Analytics Engine (NAE)
  D. Device profiles
  A. Virtual Network Based Tunneling (VNBT)

  ---

  Explanation

  Comprehensive Detailed

  Explanation

  Virtual Network Based Tunneling (VNBT) is the appropriate technology for this use case because:

  Traffic Steering: VNBT enables traffic from specific clients or devices to be tunneled through a predefined network path. This allows traffic to pass through intermediate devices such as third-party

  security appliances.

  Policy Enforcement: VNBT can be configured to route traffic based on roles, VLANs, or other policy

  definitions, ensuring that only specified traffic flows are redirected to the security appliance.

  Scalability: This approach simplifies the redirection of traffic without requiring complex physical rewiring or changes to the underlying network topology.

  Other Options:

  Network Analytics Engine (NAE): Used for monitoring and analytics, not traffic steering or forwarding.

  Device Profiles: Helps automate switch port configurations for specific device types but does not handle traffic redirection.

• Question 16:

  Refer to the exhibit.

  

  The exhibit shows a saved packet capture, which you have opened in Wireshark. You want to focus on the complete conversation between 10.1.70.90 and 10.1.79.11 that uses source port 5448.

  What is a simple way to do this in Wireshark?

  A. Apply a capture filter that selects for both the 10.1.70.90 and 10.1.79.11 IP addresses.
  B. Click the Source column and then the Destination column to sort the packets into the desired order.
  C. Apply a capture filter that selects for TCP port 5448.
  D. Right-click one of the packets between those addresses and choose to follow the stream.
  D. Right-click one of the packets between those addresses and choose to follow the stream.

  ---

  Explanation

  Wireshark: Follow TCP Stream:

  Wireshark provides an intuitive feature to filter and display a complete TCP conversation.

  By right-clicking any packet within the conversation and selecting "Follow # TCP Stream" , Wireshark isolates and displays the entire conversation.

  This feature allows you to view the communication in a simplified, sequential manner, including requests and responses.

  Option Analysis:

  Option A: Incorrect. Capture filters only apply during packet capturing, not for analyzing already saved packet captures.

  Option B: Incorrect. Sorting packets helps with organizing data but does not isolate a complete conversation.

  Option C: Incorrect. A capture filter for TCP port 5448 would have to be applied before capturing; it does not work for saved data.

  Option D: Correct. Right-clicking a packet and choosing

  "Follow TCP Stream" is the simplest

  way to display the full conversation between 10.1.70.90 and 10.1.79.11 on port 5448.

  Steps in Wireshark to Follow a TCP Stream:

  Locate any packet within the desired conversation (e.g., between 10.1.70.90 and 10.1.79.11 on TCP port 5448).

  Right-click on the packet.

  Choose

  "Follow" # "TCP Stream" .

  Wireshark will display the entire TCP conversation, including both directions of communication.

  B. Hybrid workers are exposing their computers to risky internet sites and infection by malware when they work from home.

  ---

  Explanation

  An HPE Aruba Networking Secure Web Gateway (SWG) is designed to provide secure internet access by monitoring and controlling web traffic. It primarily focuses on protecting users from malicious content and ensuring compliance with corporate security policies, particularly for hybrid and remote workers.

  Explanation of Each Option

  A. The organization needs a faster way to quarantine clients that have generated threats, as detected by third-party firewalls.

  Incorrect:

  Quarantining clients based on detected threats is typically managed by endpoint detection and response (EDR) solutions or next-generation firewalls (NGFWs).

  While an SWG can monitor and block risky web activity, it does not manage threat quarantine actions directly.

  B. Hybrid workers are exposing their computers to risky internet sites and infection by malware when they work from home.

  Correct:

  SWGs monitor and control web traffic to block malicious websites and prevent exposure to malware.

  They enforce web usage policies even when users work remotely, protecting against phishing,drive-by downloads, and other web-based threats.

  With the proliferation of hybrid work environments, an SWG ensures that users are protected from risky sites regardless of their location.

  C. Remote workers need access to private data center applications without exposing those applications to unauthorized users.

  Incorrect:

  This use case falls under secure access service edge (SASE) solutions with Zero Trust Network Access (ZTNA) , not an SWG.

  ZTNA focuses on granting secure, conditional access to applications, while SWGs focus on internet traffic security.

  D. The organization currently has no way to prevent users from exfiltrating sensitive data from SaaS applications.

  Incorrect:

  Data loss prevention (DLP) tools or cloud access security brokers (CASBs) are designed for monitoring and preventing data exfiltration from SaaS applications.

  While SWGs can block access to specific websites or categories, they do not offer advanced DLP capabilities for SaaS environments.

• Question 19:

  A company is implementing a client-to-site VPN based on tunnel-mode IPsec.

  Which devices are responsible for the IPsec encapsulation?

  A. Gateways at the remote clients' locations and devices accessed by the clients at the main site
  B. The remote clients and devices accessed by the clients at the main site
  C. The remote clients and a gateway at the main site
  D. Gateways at the remote clients' locations and a gateway at the main site
  C. The remote clients and a gateway at the main site

  ---

  Explanation

  In a client-to-site VPN based on tunnel-mode IPsec, the remote clients and a gateway at the main site are responsible for the IPsec encapsulation. The remote clients initiate the VPN connection and encapsulate their traffic in IPsec, which is

  then decapsulated by the gateway at the main site.

  1.IPsec Encapsulation: The remote clients encapsulate their traffic using IPsec protocols before sending it over the internet to the main site.

  2.Gateway Role: The gateway at the main site receives the encapsulated traffic, decapsulates it, and forwards it to the internal network. Similarly, traffic from the main site to the remote clients is encapsulated by the gateway and decapsulated

  by the clients.

  3.Security: This setup ensures that data is securely transmitted between the remote clients and the main site, protecting it from eavesdropping and tampering.

• Question 20:

  You are setting up an HPE Aruba Networking VIA solution for a company. You need to configure access control policies for applications and resources that remote clients can access when connected to the VPN.

  Where on the VPNC should you configure these policies?

  A. In the tunneled network settings within the VIA Connection Profile
  B. In the cloud security settings using IPsec maps
  C. In the roles to which VIA clients are assigned after IKE authentication
  D. In the roles to which VIA clients are assigned after VIA Web authentication
  C. In the roles to which VIA clients are assigned after IKE authentication

  ---

  Explanation

  To configure access control policies for applications and resources that remote clients can access when connected to the VPN, you should configure these policies in the roles to which VIA clients are assigned after IKE (Internet Key Exchange) authentication on the VPNC. These roles define the permissions and access controls for the clients once they are authenticated, ensuring that they can only access the applications and resources allowed by their assigned roles.

  1.IKE Authentication: After IKE authentication, clients are assigned specific roles that determine their access privileges.

  2.Role-Based Access Control: By configuring access control policies within these roles, you can granularly control what resources and applications the remote clients can access over the VPN.

  3.Security: This method ensures that access is managed securely and dynamically based on the role assigned to each client after successful authentication.
