NEW QUESTION # 30
You have a network with ArubaOS-Switches for which Aruba ClearPass Policy Manager (CPPM) is acting as a TACACS+ server to authenticate managers. CPPM assigns the admins a TACACS+ privilege level, either manager or operator. You are now adding ArubaOS-CX switches to the network. ClearPass admins want to use the same CPPM service and policies to authenticate managers on the new switches.
What should you explain?
- A. This approach will work, but will need to be adjusted later if you want to assign managers to the default auditors group.
- B. This approach cannot work because the ArubaOS-CX switches do not support TACACS+.
- C. This approach will work to assign admins to the default "administrators" group, but not to the default
"operators" group. - D. This approach cannot work because the ArubaOS-CX switches do not accept standard TACACS+ privilege levels.
Answer: C
Explanation:
With ArubaOS-CX switches, the use of ClearPass Policy Manager (CPPM) as a TACACS+ server for authentication is supported. The privilege levels assigned by CPPM will translate onto the switches, where the "manager" privilege level typically maps to administrative capabilities and the "operator" privilege level maps to more limited capabilities. ArubaOS-CX does support standard TACACS+ privilege levels, so administrators can be assigned appropriately. If the ClearPass policies are correctly configured, they will work for both ArubaOS-Switches and ArubaOS-CX switches. The distinction between the "administrators" and "operators" groups is inherent in the ArubaOS-CX role-based access control, and these default groups need to be appropriately mapped to the TACACS+ privilege levels assigned by CPPM.

- D. MAC address d8:50:e6 f3;6e;c5; Client Classification Interfering. AP Classification Neighbor
Answer: A
Explanation:
In the context of the ArubaOS Security Dashboard, if the goal is to find company clients that have connected to devices potentially operated by hackers, you would look for a client that is classified as 'Interfering' (indicating a security threat) while being connected to an 'AP Classification: Rogue'. A rogue AP is one that is not under the control of network administrators and is considered malicious or a security threat. Therefore, the client fitting this description is:
MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Rogue
NEW QUESTION # 36
What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial or service attack (DoS)?
- A. A DoS attack targets one server, a DDoS attack targets all the clients that use a server
- B. A DDoS attack is launched from multiple devices, while a DoS attack is launched from a single device
- C. A DDoS attack targets multiple devices, while a DoS Is designed to Incapacitate only one device
- D. A DDoS attack originates from external devices, while a DoS attack originates from internal devices
Answer: B
Explanation:
The main distinction between a Distributed Denial of Service (DDoS) attack and a traditional Denial of Service (DoS) attack is that a DDoS attack is launched from multiple devices, whereas a DoS attack originates from a single device. This distinction is critical because the distributed nature of a DDoS attack makes it more difficult to mitigate. Multiple attacking sources can generate a higher volume of malicious traffic, overwhelming the target more effectively than a single source, as seen in a DoS attack. DDoS attacks exploit a variety of devices across the internet, often coordinated using botnets, to flood targets with excessive requests, leading to service degradation or complete service denial.
References:
Cybersecurity texts and resources that differentiate between types of denial of service attacks.
Technical documentation and analysis of DDoS tactics, which illustrate how botnets and other distributed systems are employed to execute attacks.
NEW QUESTION # 37 
What is one thing can you determine from the exhibits?
- A. CPPM originally assigned the client to a role for non-profiled devices. It sent a CoA to the authenticator after it categorized the device.
- B. CPPM sent a CoA message to the client to prompt the client to submit information that CPPM can use to profile it.
- C. 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.
- 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: A
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 # 47
You configure an ArubaOS-Switch to enforce 802.1X authentication with ClearPass Policy Manager (CPPM) denned as the RADIUS server Clients cannot authenticate You check Aruba ClearPass Access Tracker and cannot find a record of the authentication attempt.
What are two possible problems that have this symptom? (Select two)
- A. Clients are configured to use a mismatched EAP method from the one In the CPPM service.
- B. CPPM does not have a network device defined for the switch's IP address.
- C. Clients are not configured to trust the root CA certificate for CPPM's RADIUS/EAP certificate.
- D. users are logging in with the wrong usernames and passwords or invalid certificates.
- E. The RADIUS shared secret does not match between the switch and CPPM.
Answer: C,D
NEW QUESTION # 48 
What is another setting that you must configure on the switch to meet these requirements?
- A. Configure a CPPM username and password that match a CPPM admin account.
- B. Disable SSH on the default VRF and enable it on the mgmt VRF instead.
- C. Create port-access roles with the same names of the roles that CPPM will send in Aruba-Admin-Role VSAs.
- D. Set the aaa authentication login method for SSH to the "radius" server-group (with local as backup).
Answer: D
Explanation:
To meet the requirements for configuring an ArubaOS-CX switch for integration with ClearPass Policy Manager (CPPM), it is necessary to set the AAA authentication login method for SSH to use the "radius" server-group, with "local" as a backup. This ensures that when an admin attempts to SSH into the switch, the authentication request is first sent to CPPM via RADIUS. If CPPM is unavailable, the switch will fall back to using local authentication12.
Here's why the other options are not correct:
Option B is incorrect because configuring a CPPM username and password on the switch that matches a CPPM admin account is not required for SSH login; rather, the switch needs to be configured to communicate with CPPM for authentication.
Option C is incorrect because while CPPM will send Aruba-Admin-Role Vendor-Specific Attributes (VSAs), the switch does not need to have port-access roles created with the same names; it needs to interpret the VSA to assign the correct role.
Option D is incorrect because disabling SSH on the default VRF and enabling it on the mgmt VRF is not related to the authentication process with CPPM.
Therefore, the correct answer is A, as setting the AAA authentication login method for SSH to the "radius" server-group with "local" as backup is a key step in ensuring that the switch can authenticate admins through CPPM while providing a fallback method12.
NEW QUESTION # 49 
A company has added a new user group. Users in the group try to connect to the WLAN and receive errors that the connection has no Internet access. The users cannot reach any resources. The first exhibit shows the record for one of the users who cannot connect. The second exhibit shows the role to which the ArubaOS device assigned the user's client.
What is a likely problem?
- A. The clients rejected the server authentication on their side because they do not have the root CA for CPPM's RADIUS/EAP certificate.
- B. The ArubaOS device has a server derivation rule configured on it that has overridden the role sent by CPPM.
- C. The ArubaOS device does not have the correct RADIUS dictionaries installed on it to under-stand the Aruba-User-Role VSA.
- D. The role name that CPPM is sending does not match the role name configured on the Aru-baOS device.
Answer: D
Explanation:
The image indicates that there is an issue with the user role assignment, which is key to network access in ArubaOS. If the user role name sent by CPPM doesn't match any of the roles defined in the ArubaOS, then the user will be assigned a default or incorrect role that does not have the necessary permissions, thus leading to the connection errors and lack of Internet access. Ensuring that the role names are consistent between CPPM and ArubaOS can resolve this issue.
NEW QUESTION # 50
Refer to the exhibit.
A diem is connected to an ArubaOS Mobility Controller. The exhibit snows all Tour firewall rules that apply to this diem What correctly describes how the controller treats HTTPS packets to these two IP addresses, both of which are on the other side of the firewall
10.1 10.10
203.0.13.5
- A. it permits both of the packets
- B. It permits the packet to 10.1.10.10 and drops the packet to 203 0.13.5
- C. It drops both of the packets
- D. It drops the packet to 10.1.10.10 and permits the packet to 203.0.13.5.
Answer: B
Explanation:
Referring to the exhibit, the ArubaOS Mobility Controller treats HTTPS packets based on the firewall rules applied to the client. The rule that allows svc-https service for destination IP range 10.1.0.0 255.255.0.0 would permit an HTTPS packet to 10.1.10.10 since this IP address falls within the specified range. There are no rules shown that would allow traffic to the IP address 203.0.13.5; hence, the packet to this address would be dropped.

ArubaOS firewall configuration guides detailing how firewall rules are interpreted and applied to traffic.
Network security textbooks explaining firewall rule processing and packet filtering based on source and destination IP addresses.
NEW QUESTION # 51
What is one of the roles of the network access server (NAS) in the AAA framewonx?
- A. It authenticates legitimate users and uses policies to determine which resources each user is allowed to access.
- B. It enforces access to network services and sends accounting information to the AAA server
- C. It determines which resources authenticated users are allowed to access and monitors each users session
- D. It negotiates with each user's device to determine which EAP method is used for authentication
Answer: B
Explanation:
In the AAA (Authentication, Authorization, and Accounting) framework, the role of the Network Access Server (NAS) is to act as a gateway that enforces access to network services and sends accounting information to the AAA server. The NAS initially requests authentication information from the user and then passes that information to the AAA server. It also enforces the access policies as provided by the AAA server after authentication and provides accounting data to the AAA server based on user activity.
References:
Technical literature on AAA protocols which often includes a description of the roles and responsibilities of a Network Access Server.
Network security resources that discuss the NAS function within the AAA framework.
NEW QUESTION # 52
What is one way that WPA3-Enterprise enhances security when compared to WPA2-Enterprise?
- A. WPA3-Enterprise can operate in CNSA mode, which mandates that the 802.11 association uses secure algorithms.
- B. WPA3-Enterprise uses Diffie-Hellman in order to authenticate clients, while WPA2-Enterprise uses
802.1X authentication. - C. WPA3-Enterprise implements the more secure simultaneous authentication of equals (SAE), while WPA2-Enterprise uses 802.1X.
- D. WPA3-Enterprise provides built-in mechanisms that can deploy user certificates to authorized end-user devices.
Answer: A
Explanation:
WPA3-Enterprise enhances network security over WPA2-Enterprise through several improvements, one of which is the ability to operate in CNSA (Commercial National Security Algorithm) mode. This mode mandates the use of secure cryptographic algorithms during the 802.11 association process, ensuring that all communications are highly secure. The CNSA suite provides stronger encryption standards designed to protect sensitive government, military, and industrial communications. Unlike WPA2, WPA3's CNSA mode uses stronger cryptographic primitives, such as AES-256 in Galois/Counter Mode (GCM) for encryption and SHA-384 for hashing, which are not standard in WPA2-Enterprise.
