NEW QUESTION # 69
You have been authorized to use containment to respond to rogue APs detected by ArubaOS Wireless Intrusion Prevention (WIP). What is a consideration for using tarpit containment versus traditional wireless containment?

A. Rather than target all clients connected to rogue APs, tarpit containment targets only authorized clients that are connected to a rogue AP, reducing the chance of negative effects on neighbors.
B. Tarpit containment does not require an RF Protect license to function, while traditional wireless containment does.
C. Tarpit containment forms associations with clients to enable more effective containment with fewer disassociation frames than traditional wireless containment.
D. Rather than function wirelessly, tarpit containment sends ARP frames over the wired network to poison rogue APs ARP tables and prevent them from transmitting on the wired network.

Answer: C

Explanation:
Tarpit containment is a method used in ArubaOS Wireless Intrusion Prevention (WIP) to contain rogue APs.
It differs from traditional wireless containment in several ways, particularly in how it interacts with clients and manages network resources.
Tarpit containment works by spoofing frames from an AP to confuse a client about its association. It forces the client to associate with a fake channel or BSSID, which is more efficient than rogue containment via repeated de-authorization requests. This method is designed to be less disruptive and more resource-efficient1.
Here's why the other options are not correct:
Option A is incorrect because tarpit containment does not involve sending ARP frames over the wired network. It operates wirelessly by creating a fake channel or BSSID.
Option B is incorrect because tarpit containment does not selectively target authorized clients; it affects all clients connected to the rogue AP.
Option C is incorrect because tarpit containment does require an RF Protect license to function2.
Therefore, Option D is the correct answer. Tarpit containment is more effective at keeping clients off the network with fewer disassociation frames than traditional wireless containment. It achieves this by forming associations with clients, which leads to a more efficient use of airtime and reduces the chance of negative effects on legitimate network users12.

NEW QUESTION # 70
You are deploying a new wireless solution with an Aruba Mobility Master (MM). Aruba 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 between MC ports and the core routing switches
B. only links on the path between APs and the MC
C. only links in the campus LAN to ensure seamless roaming
D. only links on the path between APs and the core routing switches

Answer: A

Explanation:
In a wireless network deployment with Aruba Mobility Master (MM), Mobility Controllers (MCs), and Campus APs (CAPs), where a WLAN is configured to use Tunnel mode for forwarding, the user traffic is tunneled from the APs to the MCs. VLAN 301, which is assigned to the WLAN, must be present on the links from the MCs to the core routing switches because these switches act as the default router for the wireless user traffic. It is not necessary for the VLAN to be present on all campus LAN links or AP links, only between the MCs and the core routing switches where the routing for VLAN 301 will occur.

NEW QUESTION # 71
What correctly describes the Pairwise Master Key (PMK) in thee specified wireless security protocol?

A. In WPA3-Personal, the PMK is derived directly from the passphrase and is the same tor every session.
B. In WPA3-Enterprise, the PMK is unique per session and derived using Simultaneous Authentication of Equals.
C. In WPA3-Personal, the PMK is unique per session and derived using Simultaneous Authentication of Equals.
D. In WPA3-Personal, the PMK is the same for each session and is communicated to clients that authenticate

Answer: B

Explanation:
In WPA3-Enterprise, the Pairwise Master Key (PMK) is indeed unique for each session and is derived using a process called Simultaneous Authentication of Equals (SAE). SAE is a new handshake protocol available in WPA3 that provides better security than the Pre-Shared Key (PSK) used in WPA2. This handshake process strengthens user privacy in open networks and provides forward secrecy. The information on SAE and its use in generating a unique PMK can be found in the Wi-Fi Alliance's WPA3 specifications and related technical documentation.

NEW QUESTION # 72
You have been asked to rind logs related to port authentication on an ArubaOS-CX switch for events logged in the past several hours But. you are having trouble searching through the logs What is one approach that you can take to find the relevant logs?

A. Add the "-C and *-c port-access" options to the "show logging" command.
B. Configure a logging Tiller for the "port-access" category, and apply that filter globally.
C. Specify a logging facility that selects for "port-access" messages.
D. Enable debugging for "portaccess" to move the relevant logs to a buffer.

Answer: A

NEW QUESTION # 73
Refer to the exhibits.
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 the MC could not contact the authentication server.
B. The client has attempted 802.1X authentication, but failed to maintain a reliable connection, leading to a timeout error.
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:
The exhibit shows the configuration of a WLAN on an AOS-8 Mobility Controller (MC) with the following settings:
Key management: WPA3-Enterprise (indicating 802.1X authentication).
Use CNSA suite: Unchecked (using standard encryption, not the Commercial National Security Algorithm suite).
Key size: 128 bits (standard for AES-GCMP in WPA3).
Reauth interval: 1440 minutes (24 hours, the interval for re-authentication).
Machine authentication: Disabled (only user authentication is required).
Blacklisting: Disabled (clients are not blacklisted after failed attempts).
The question states that the AAA profile settings have not been adjusted, meaning the default roles (e.g., initial role, logon role, 802.1X default role) are not specified in the exhibit and are assumed to be the system defaults (e.g., "logon" for the initial and logon roles, and a default role like "guest" for the 802.1X default role). The question asks under which circumstances a client will receive the "default role assignment," which refers to the 802.1X default role configured in the AAA profile for the WLAN.
802.1X Authentication Process in AOS-8:
When a client connects to a WPA3-Enterprise WLAN, it starts in the initial role (typically "logon") to allow basic connectivity (e.g., DHCP, DNS).
During 802.1X authentication, the client is placed in the logon role to allow communication with the authentication server (e.g., ClearPass Policy Manager, CPPM).
If authentication succeeds, the client is assigned a role:
If the authentication server (e.g., CPPM) sends an Aruba-User-Role VSA with a role that exists on the MC, the client is assigned that role.
If no Aruba-User-Role VSA is sent, the client is assigned the 802.1X default role configured in the AAA profile for the WLAN.
If authentication fails or the server is unreachable, the client may be assigned a different role (e.g., a critical role, if configured) or denied access.
Option A, "The client has attempted 802.1X authentication, but the MC could not contact the authentication server," is incorrect. If the MC cannot contact the authentication server (e.g., due to a timeout), the client does not receive the 802.1X default role. Instead, the MC may apply a critical role (if configured) or deny access, depending on the configuration. The 802.1X default role is applied only after successful authentication.
Option B, "The client has passed 802.1X authentication, and the authentication server did not send an Aruba-User-Role VSA," is correct. If the client successfully authenticates via 802.1X and the authentication server (e.g., CPPM) does not send an Aruba-User-Role VSA, the MC assigns the client the 802.1X default role configured in the AAA profile for the WLAN. This is the "default role assignment" referred to in the question.
Option C, "The client has attempted 802.1X authentication, but failed to maintain a reliable connection, leading to a timeout error," is incorrect. A timeout error during authentication (e.g., the client fails to respond to EAP messages) typically results in an authentication failure, not a successful authentication. The client would not receive the 802.1X default role; it might be denied access or placed in a different role (e.g., a pre-authentication role).
Option D, "The client has passed 802.1X authentication, and the value in the Aruba-User-Role VSA matches a role on the MC," is incorrect. If the authentication server sends an Aruba-User-Role VSA with a role that exists on the MC, the client is assigned that specific role, not the 802.1X default role.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"After a client successfully authenticates via 802.1X, the Mobility Controller assigns a role to the client. If the authentication server (e.g., a RADIUS server) sends an Aruba-User-Role VSA with a role that exists on the controller, the client is assigned that role. If no Aruba-User-Role VSA is sent in the Access-Accept message, the client is assigned the 802.1X default role configured in the AAA profile for the WLAN. For example, if the AAA profile specifies 'guest' as the 802.1X default role, the client will be assigned the 'guest' role." (Page 305, Role Assignment Section) Additionally, the HPE Aruba Networking Wireless Security Guide notes:
"In WPA3-Enterprise with 802.1X authentication, the default role assignment occurs when a client successfully authenticates but the authentication server does not specify a role via the Aruba-User-Role VSA. In this case, the client receives the 802.1X default role defined in the AAA profile, such as 'guest' or another role configured by the administrator." (Page 42, 802.1X Role Assignment Section)
