HP Aruba Certified Network Security Associate Exam Sample Questions (Q168-Q173):

NEW QUESTION # 168
Refer to the exhibit.

This Aruba Mobility Controller (MC) should authenticate managers who access the Web Ul to ClearPass Policy Manager (CPPM) ClearPass admins have asked you to use RADIUS and explained that the MC should accept managers' roles in Aruba-Admin-Role VSAs Which setting should you change to follow Aruba best security practices?

A. Clear the MSCHAP check box
B. Disable local authentication
C. Change the default role to "guest-provisioning"
D. Change the local user role to read-only

Answer: B

Explanation:
For following Aruba best security practices, the setting you should change is to disable local authentication. When integrating with an external RADIUS server like ClearPass Policy Manager (CPPM) for authenticating administrative access to the Mobility Controller (MC), it is a best practice to rely on the external server rather than the local user database. This practice not only centralizes the management of user roles and access but also enhances security by leveraging CPPM's advanced authentication mechanisms.
:
Aruba Networks official best practice documentation, which recommends centralized authentication for administrative access.
Security standards and guidelines that promote the use of external RADIUS servers for authentication purposes.

NEW QUESTION # 169
What is a benefit of Protected Management Frames (PMF). sometimes called Management Frame Protection (MFP)?

A. PMF prevents hackers from capturing the traffic between APs and Mobility Controllers.
B. PMF helps to protect APs and MCs from unauthorized management access by hackers.
C. PMF protects clients from DoS attacks based on forged de-authentication frames
D. PMF ensures trial traffic between APs and Mobility Controllers (MCs) is encrypted.

Answer: C

Explanation:
Protected Management Frames (PMF), also known as Management Frame Protection (MFP), is designed to protect clients from denial-of-service (DoS) attacks that involve forged de-authentication and disassociation frames. These attacks can disconnect legitimate clients from the network. PMF provides a way to authenticate these management frames, ensuring that they are not forged, thus enhancing the security of the wireless network.
References:
IEEE 802.11w amendment, which introduces PMF as a security enhancement to protect management frames.
Wi-Fi Alliance security guidelines for Protected Management Frames (PMF).

NEW QUESTION # 170
You are deploying a new wireless solution with an HPE Aruba Networking Mobility Master (MM), 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 on the path between APs and the MC
B. Only links on the path between APs and the core routing switches
C. Only links between MC ports and the core routing switches
D. All links in the campus LAN to ensure seamless roaming

Answer: C

Explanation:
In an HPE Aruba Networking AOS-8 architecture with a Mobility Master (MM), Mobility Controllers (MCs), and campus APs (CAPs), the WLAN is configured to use Tunnel forwarding mode and WPA3-Enterprise security. In Tunnel mode, all user traffic from the APs is encapsulated in a GRE tunnel and sent to the MC, which then forwards the traffic to the appropriate VLAN. The WLAN is assigned to VLAN 301, and the core routing switches act as the default router for wireless user traffic.
Tunnel Forwarding Mode: In this mode, the AP does not directly place user traffic onto the wired network. Instead, the AP tunnels all user traffic to the MC over a GRE tunnel. The MC then decapsulates the traffic and places it onto the wired network in the specified VLAN (VLAN 301 in this case). This means the VLAN tagging for user traffic occurs at the MC, not at the AP.
VLAN 301 Assignment: Since the WLAN is assigned to VLAN 301, the MC will tag user traffic with VLAN 301 when forwarding it to the wired network. The core routing switches, acting as the default router, need to receive this traffic on VLAN 301 to route it appropriately.
Therefore, VLAN 301 needs to be carried on the links between the MC ports and the core routing switches, as this is where the MC forwards the user traffic after decapsulating it from the GRE tunnel.
Option A, "Only links on the path between APs and the core routing switches," is incorrect because, in Tunnel mode, the APs do not directly forward user traffic to the wired network. The traffic is tunneled to the MC, so the links between the APs and the core switches do not need to carry VLAN 301 for user traffic (though they may carry other VLANs for AP management).
Option B, "Only links on the path between APs and the MC," is incorrect for the same reason. The GRE tunnel between the AP and MC carries encapsulated user traffic, and VLAN 301 tagging occurs at the MC, not on the AP-to-MC link.
Option C, "All links in the campus LAN to ensure seamless roaming," is incorrect because VLAN 301 only needs to be present where the MC forwards user traffic to the wired network (i.e., between the MC and the core switches). Extending VLAN 301 to all links is unnecessary and could introduce security or scalability issues.
Option D, "Only links between MC ports and the core routing switches," is correct because the MC places user traffic onto VLAN 301 and forwards it to the core switches, which act as the default router.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"In Tunnel forwarding mode, the AP encapsulates all user traffic in a GRE tunnel and sends it to the Mobility Controller (MC). The MC decapsulates the traffic and forwards it to the wired network on the VLAN assigned to the WLAN. For example, if the WLAN is assigned to VLAN 301, the MC tags the user traffic with VLAN 301 and sends it out of its wired interface to the upstream switch. Therefore, the VLAN must be configured on the links between the MC and the upstream switch or router that acts as the default gateway for the VLAN." (Page 275, Tunnel Forwarding Mode Section) Additionally, the HPE Aruba Networking Wireless LAN Design Guide notes:
"When using Tunnel mode, the VLAN assigned to the WLAN must be carried on the wired links between the Mobility Controller and the default router for the VLAN. The links between the APs and the MC do not need to carry the user VLAN, as all traffic is tunneled to the MC, which handles VLAN tagging." (Page 52, VLAN Configuration Section)

NEW QUESTION # 171
What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial or service attack (DoS)?

A. A DDoS attack targets multiple devices, while a DoS Is designed to Incapacitate only one device
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 originates from external devices, while a DoS attack originates from internal devices

Answer: D

NEW QUESTION # 172
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 every rule that includes the client's IP address as the source or destination.
C. The firewall applies the rules in policies associated with the client's wlan
D. The firewall applies thee rules in policies associated with the client's user role.

Answer: D

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.
:
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.
