Question # 1
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 |
D. The client has passed 802 1X authentication and the authentication server did not send
an Aruba-User-Role VSA
Explanation: In the context of an Aruba Mobility Controller (MC) configuration, a client will
receive the default role assignment if they have passed 802.1X authentication and the
authentication server did not send an Aruba-User-Role Vendor Specific Attribute (VSA).
The default role is assigned by the MC when a client successfully authenticates but the
authentication server provides no specific role instruction. This behavior ensures that a
client is not left without any role assignment, which could potentially lead to a lack of
network access or access control. This default role assignment mechanism is part of
Aruba's role-based access control, as documented in the ArubaOS user guide and best
practices.
Question # 2
| 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 ClearPass admins tell you that they want to run Network scans as
part of the solution.
What should you do to configure the infrastructure to support the scans? |
| A. Create a TA profile on the ArubaOS-Switches with the root CA certificate for
ClearPass's HTTPS certificate | | B. Create device fingerprinting profiles on the ArubaOS-Switches that include SNMP. and
apply the profiles to edge ports | | C. Create remote mirrors on the ArubaOS-Swrtches that collect traffic on edge ports, and
mirror it to CPPM's IP address. | | D. Create SNMPv3 users on ArubaOS-CX switches, and make sure that the credentials
match those configured on CPPM |
D. Create SNMPv3 users on ArubaOS-CX switches, and make sure that the credentials
match those configured on CPPM
Explanation:
To configure the infrastructure to support network scans as part of the ClearPass Policy
Manager (CPPM) solution, creating SNMPv3 users on ArubaOS-CX switches is necessary.
Ensuring that the credentials for these SNMPv3 users match those configured on CPPM is
crucial for enabling CPPM to perform network scans effectively. SNMPv3 provides a
secure method for network management by offering authentication and encryption, which
are essential for safely conducting scans that classify endpoints by type. This configuration
allows CPPM to communicate securely with the switches and gather necessary data
without compromising network security.
Question # 3
| What are the roles of 802.1X authenticators and authentication servers? |
| A. The authenticator stores the user account database, while the server stores access
policies. | | B. The authenticator supports only EAP, while the authentication server supports only
RADIUS. | | C. The authenticator is a RADIUS client and the authentication server is a RADIUS server. | | D. The authenticator makes access decisions and the server communicates them to the
supplicant. |
C. The authenticator is a RADIUS client and the authentication server is a RADIUS server.
Explanation: In the 802.1X network access control model, the roles of the authenticator
and the authentication server are distinct yet complementary. The authenticator acts as a
RADIUS client, which is a network device, like a switch or wireless access point, that
directly interfaces with the client machine (supplicant). The authentication server, typically a
RADIUS server, is responsible for verifying the credentials provided by the supplicant
through the authenticator. This setup helps in separating the duties where the authenticator
enforces authentication but does not decide on the validity of the credentials, which is the
role of the authentication server.
Question # 4
Refer to the exhibit.
Device A is establishing an HTTPS session with the Arubapedia web sue using Chrome.
The Arubapedia web server sends the certificate shown in the exhibit.
What does the browser do as part of vacating the web server certificate? |
| A. It uses the public key in the DigCen SHA2 Secure Server CA certificate to check the
certificate's signature. | | B. It uses the public key in the DigCert root CA certificate to check the certificate signature | | C. It uses the private key in the DigiCert SHA2 Secure Server CA to check the certificate's
signature. | | D. It uses the private key in the Arubapedia web site's certificate to check that certificate's
signature |
A. It uses the public key in the DigCen SHA2 Secure Server CA certificate to check the
certificate's signature.
Explanation: When a browser, like Chrome, is validating a web server's certificate, it uses
the public key in the certificate's signing authority to verify the certificate's digital signature.
In the case of the exhibit, the browser would use the public key in the DigiCert SHA2
Secure Server CA certificate to check the signature of the Arubapedia web server's
certificate. This process ensures that the certificate was indeed issued by the claimed
Certificate Authority (CA) and has not been tampered with.
Question # 5
| You are managing an Aruba Mobility Controller (MC). What is a reason for adding a "Log
Settings" definition in the ArubaOS Diagnostics > System > Log Settings page? |
| A. Configuring the Syslog server settings for the server to which the MC forwards logs for a
particular category and level | | B. Configuring the MC to generate logs for a particular event category and level, but only
for a specific user or AP. | | C. Configuring a filter that you can apply to a defined Syslog server in order to filter events
by subcategory | | D. Configuring the log facility and log format that the MC will use for forwarding logs to all
Syslog servers |
A. Configuring the Syslog server settings for the server to which the MC forwards logs for a
particular category and level
Explanation: The primary reason for adding a "Log Settings" definition in the ArubaOS
Diagnostics > System > Log Settings page is to configure the Syslog server settings for the
server to which the Mobility Controller (MC) forwards logs for a particular category and
level. This setting enables the MC to send detailed logs to a Syslog server for centralized
logging and monitoring, which is essential for troubleshooting, security analysis, and
compliance with various policies.
Question # 6
| What does the NIST model for digital forensics define? |
| A. how to define access control policies that will properly protect a company's most
sensitive data and digital resources | | B. how to properly collect, examine, and analyze logs and other data, in order to use it as
evidence in a security investigation | | C. which types of architecture and security policies are best equipped to help companies
establish a Zero Trust Network (ZTN) | | D. which data encryption and authentication algorithms are suitable for enterprise networks
in a world that is moving toward quantum computing |
B. how to properly collect, examine, and analyze logs and other data, in order to use it as
evidence in a security investigation
Explanation: The National Institute of Standards and Technology (NIST) provides
guidelines on digital forensics, which include methodologies for properly collecting,
examining, and analyzing digital evidence. This framework helps ensure that digital
evidence is handled in a manner that preserves its integrity and maintains its admissibility
in legal proceedings:
Digital Forensics Process: This process involves steps to ensure that data
collected from digital sources can be used reliably in investigations and court
cases, addressing chain-of-custody issues, proper evidence handling, and detailed
documentation of forensic procedures.
Question # 7
| You are deploying an Aruba Mobility Controller (MC). What is a best practice for setting up
secure management access to the ArubaOS Web UP |
| A. Avoid using external manager authentication tor the Web UI.
| | B. Change the default 4343 port tor the web UI to TCP 443.
| | C. Install a CA-signed certificate to use for the Web UI server certificate.
| | D. Make sure to enable HTTPS for the Web UI and select the self-signed certificate
Installed in the factory. |
C. Install a CA-signed certificate to use for the Web UI server certificate.
Explanation: For securing management access to the ArubaOS Web UI of an Aruba
Mobility Controller (MC), it is a best practice to install a certificate signed by a Certificate
Authority (CA). This ensures that communications between administrators and the MC are
secured with trusted encryption, which greatly reduces the risk of man-in-the-middle
attacks. Using a CA-signed certificate enhances the trustworthiness of the connection over
self-signed certificates, which do not offer the same level of assurance.
Question # 8
Refer to the exhibit, which shows the settings on the company’s MCs.

You have deployed about 100 new Aruba 335-APs. What is required for the APs to
become managed? |
| A. installing CA-signed certificates on the APs
| | B. installing self-signed certificates on the APs
| | C. approving the APs as authorized APs on the AP whitelist
| | D. configuring a PAPI key that matches on the APs and MCs |
C. approving the APs as authorized APs on the AP whitelist
Explanation: Based on the exhibit, which shows the settings on the company's Mobility
Controllers (MCs), with 'Control Plane Security' enabled and 'Enable auto cert provisioning'
available, new Aruba 335-APs require approval on the MC to become managed. This is
commonly done by adding the APs to an authorized AP whitelist, after which they can be
automatically provisioned with certificates generated by the MC.
