NEW QUESTION # 14
You have deployed a new Aruba Mobility Controller (MC) and campus APs (CAPs). One of the WLANs enforces 802.IX authentication lo Aruba ClearPass Policy Manager {CPPM) When you test connecting the client to the WLAN. the test falls You check Aruba ClearPass Access Tracker and cannot find a record of the authentication attempt You ping from the MC to CPPM. and the ping is successful.
What is a good next step for troubleshooting?
- A. Renew CPPM's RADIUS/EAP certificate
- B. Check connectivity between CPPM and a backend directory server
- C. Check CPPM Event viewer.
- D. Reset the user credentials
Answer: C
Explanation:
When dealing with a failed 802.1X authentication attempt to a WLAN enforced by Aruba ClearPass Policy Manager (CPPM) where no record of the attempt is seen in ClearPass Access Tracker, a good next troubleshooting step is to check the CPPM Event Viewer. Since you are able to successfully ping from the Mobility Controller to CPPM, this indicates that there is network connectivity between these two devices.
The lack of a record in Access Tracker suggests that the issue may not be with the RADIUS/EAP certificate or user credentials, but possibly with the ClearPass service itself or its reception of authentication requests.
The Event Viewer can provide detailed logs that might reveal internal errors or misconfigurations within CPPM that could prevent it from processing authentication attempts properly.
NEW QUESTION # 15
Your company policies require you to encrypt logs between network infrastructure devices and Syslog servers. What should you do to meet these requirements on an ArubaOS-CX switch?
- A. Specify the Syslog server with the TLS option and make sure the switch has a valid certificate.
- B. Set up RadSec and then enable Syslog as a protocol carried by the RadSec tunnel.
- C. Specify a priv key with the Syslog settings that matches a priv key on the Syslog server.
- D. Specify the Syslog server with the UDP option and then add an CPsec tunnel that selects Syslog.
Answer: A
Explanation:
To ensure secure transmission of log data over the network, particularly when dealing with sensitive or critical information, using TLS (Transport Layer Security) for encrypted communication between network devices and syslog servers is necessary:
Secure Logging Setup: When configuring an ArubaOS-CX switch to send logs securely to a Syslog server, specifying the server with the TLS option ensures that all transmitted log data is encrypted.
Additionally, the switch must have a valid certificate to establish a trusted connection, preventing potential eavesdropping or tampering with the logs in transit.
Other Options:
Option B, Option C, and Option D are less accurate or applicable for directly encrypting log data between the device and Syslog server as specified in the company policies.

NEW QUESTION # 18
An ArubaOS-CX switch enforces 802.1X on a port. No fan-through options or port-access roles are configured on the port The 802 1X supplicant on a connected client has not yet completed authentication Which type of traffic does the authenticator accept from the client?
- A. DHCP, DNS and RADIUS only
- B. DHCP, DNS, and EAP only
- C. RADIUS only
- D. EAP only
Answer: D
Explanation:
For an ArubaOS-CX switch enforcing 802.1X on a port without any fallback options or port-access roles configured, and where the supplicant on the connected client has not completed authentication, the only type of traffic the authenticator accepts from the client is EAP (Extensible Authentication Protocol). EAP is a universal authentication framework used in 802.1X for message exchange during the authentication process.
The switch allows EAP packets because they are necessary for the client and the authentication server to perform the authentication process. This is standard behavior for 802.1X authenticators, which is to permit EAP traffic to pass through even before authentication is successful to facilitate the authentication exchange.
This information is supported by the IEEE 802.1X standard and ArubaOS-CX security configuration guides.

NEW QUESTION # 20
What is a use case for implementing RadSec instead of RADIUS?
- A. A corporation wants to implement EAP-TLS to authenticate wireless users at their main office.
- B. A school district wants to protect messages sent between RADIUS clients and servers over an untrusted network.
- C. A organization wants to strengthen the encryption used to protect RADIUS communications without increasing complexity.
- D. A university wants to protect communications between the students' devices and the network access server.
Answer: B
Explanation:
RadSec (RADIUS over TLS) is a protocol for transporting RADIUS messages over TLS-encrypted TCP/IP networks. The primary use case for implementing RadSec instead of traditional RADIUS is to protect RADIUS communications, particularly when those messages must travel across an untrusted network, such as the internet. RadSec provides confidentiality, integrity, and authentication for RADIUS traffic between clients and servers which may not be within a single secure network. In the case of a school district that wants to ensure the security of messages sent between RADIUS clients and servers over potentially insecure networks, RadSec would be the appropriate choice.
NEW QUESTION # 21
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 the packet to 10.1.10.10 and drops the packet to 203 0.13.5
- B. It drops both of the packets
- C. it permits both of the packets
- D. It drops the packet to 10.1.10.10 and permits the packet to 203.0.13.5.
Answer: A
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.

NEW QUESTION # 23
You need to set up Aruba network infrastructure devices for management with SNMP. The SNMP server has this SNMPv3 user configured on it: username: airwave auth algorithm: sha auth key: fyluqp18@S!9a priv algorithm: aes priv key: 761oxaiaoeu19& What correctly describes the setup on the infrastructure device?
- A. You must configure the "airwave" server as an authorized user. Then, configure a separate user for this device with its own keys.
- B. You must configure a user with exactly the same name, algorithms, and keys.
- C. You must configure a user with the same name and keys, but can choose algorithms that meet the device's needs.
- D. You must configure a user with the same name and algorithms, but the keys should be unique to this device.
Answer: B
Explanation:
In SNMPv3, security is paramount and each SNMP entity (client or agent) needs to have a user with a security name (username) and optionally, a security level which determines whether authentication and encryption are used. When configuring SNMPv3 users on network infrastructure devices, it is essential to match the username, authentication (auth) algorithm, authentication key (auth key), privacy (priv) algorithm, and privacy key (priv key) exactly as they are configured on the SNMP server to ensure successful communication.
This is because the SNMPv3 security model relies on a combination of a username and a pair of keys (authentication and privacy keys) to uniquely identify and secure communication between the agent and the manager. The keys are used to verify the integrity (auth key) and confidentiality (priv key) of the messages.
Using the same algorithms ensures that the messages can be properly encrypted and decrypted on both ends.
NEW QUESTION # 24

Answer: D
NEW QUESTION # 26
What is a vulnerability of an unauthenticated Dime-Heliman exchange?
- A. A hacker can replace the public values exchanged by the legitimate peers and launch an MITM attack.
- B. Participants must agree on a passphrase in advance, which can limit the usefulness of Diffie- Hell man in practical contexts.
- C. A brute force attack can relatively quickly derive Diffie-Hellman private values if they are able to obtain public values
- D. Diffie-Hellman with elliptic curve values is no longer considered secure in modem networks, based on NIST recommendations.
Answer: A
Explanation:
The vulnerability of an unauthenticated Diffie-Hellman exchange, particularly when it comes to the risk of a man-in-the-middle (MITM) attack, is a significant concern. In this scenario, a hacker can intercept the public values exchanged between two legitimate parties and substitute them with their own. This allows the attacker to decrypt or manipulate the messages passing between the two original parties without them knowing. This answer is based on the fundamental principles of how Diffie-Hellman key exchange works and its vulnerabilities without authentication mechanisms. Reference materials from cryptographic textbooks and security protocols detail these vulnerabilities, such as those found in standards and publications by organizations like NIST.

- A. Use RadSec for enforcing 802.1X authentication to ClearPass.
- B. Synchronize its clock with an NTP server that requires authentication.
- C. Obtain downloadable user roles (DURs) from ClearPass.
- D. Use RADIUS for enforcing 802.1X authentication to ClearPass.
Answer: A
Explanation:
A Server Certificate is required by Aruba Mobility Controller when using RadSec to secure RADIUS communication. RadSec provides a secure transport for RADIUS traffic through SSL/TLS which requires the use of a Server Certificate to establish the secure tunnel. In the other scenarios listed, a Server Certificate is not explicitly required for the operations mentioned.
NEW QUESTION # 29 
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 ArubaOS device does not have the correct RADIUS dictionaries installed on it to under-stand the Aruba-User-Role VSA.
- B. The clients rejected the server authentication on their side because they do not have the root CA for CPPM's RADIUS/EAP certificate.
- C. The ArubaOS device has a server derivation rule configured on it that has overridden the role sent by CPPM.
- 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.

A company has Aruba Mobility Controllers (MCs), Aruba campus APs, and ArubaOS-CX switches. The company plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type. The company is contemplating the use of ClearPass's TCP fingerprinting capabilities.
What is a consideration for using those capabilities?
- A. ClearPass admins will need to provide the credentials of an API admin account to configure on Aruba devices.
- B. You will need to mirror traffic to one of CPPM's span ports from a device such as a core routing switch.
- C. ArubaOS-CX switches do not offer the support necessary for CPPM to use TCP fingerprinting on wired endpoints.
- D. TCP fingerprinting of wireless endpoints requires a third-party Mobility Device Management (MDM) solution.
Answer: B
Explanation:
ClearPass Policy Manager (CPPM) uses various methods to classify endpoints, and one of them is TCP fingerprinting, which involves analyzing TCP/IP packets to identify the type of device or operating system sending them. To utilize TCP fingerprinting capabilities, network traffic needs to be accessible to the CPPM.
This can be done by mirroring traffic to CPPM's span port from a device that can see the traffic, like a core routing switch. This approach allows CPPM to observe the TCP characteristics of devices as they communicate over the network, enabling it to make more accurate decisions for device classification.

What is one way a noneypot can be used to launch a man-in-the-middle (MITM) attack to wireless clients?
- A. it uses a combination or software and hardware to jam the RF band and prevent the client from connecting to any wireless networks
- B. it uses ARP poisoning to disconnect wireless clients from the legitimate wireless network and force clients to connect to the hacker's wireless network instead.
- C. it runs an NMap scan on the wireless client to And the clients MAC and IP address. The hacker then connects to another network and spoofs those addresses.
- D. it examines wireless clients' probes and broadcasts the SSlDs in the probes, so that wireless clients will connect to it automatically.
Answer: D
Explanation:
A honeypot can be used to launch a Man-in-the-Middle (MITM) attack on wireless clients by examining wireless clients' probe requests and then broadcasting the SSIDs in those probes. Clients with those SSIDs in their preferred network list may then automatically connect to the honeypot, believing it to be a legitimate network. Once the client is connected to the attacker's honeypot, the attacker can intercept, monitor, or manipulate the client's traffic, effectively executing a MITM attack.
