This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the HP Aruba Certified Network Security Professional Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by HP in their HPE7-A02 exam. These outdated questions lead to customers failing their HP Aruba Certified Network Security Professional Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the HPE7-A02 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
You are using OpenSSL to obtain a certificate signed by a Certification Authority (CA). You have entered this command:
openssl req -new -out file1.pem -newkey rsa:3072 -keyout file2.pem
Enter PEM pass phrase: **********
Verifying - Enter PEM pass phrase: **********
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:California
Locality Name (eg, city) []:Sunnyvale
Organization Name (eg, company) [Internet Widgits Pty Ltd]:example.com
Organizational Unit Name (eg, section) []:Infrastructure
Common Name (e.g. server FQDN or YOUR name) []:radius.example.com
What is one guideline for continuing to obtain a certificate?
When using OpenSSL to obtain a certificate signed by a Certification Authority (CA), you should submit the Certificate Signing Request (CSR) file, which is file1.pem, to the CA. The CSR contains the information about the entity requesting the certificate and the public key, but not the private key, which is in file2.pem. The CA uses the information in the CSR to create and sign the certificate.
1. CSR Submission: The CSR (file1.pem) includes the public key and the entity information required by the CA to issue a certificate.
2. Private Key Security: The private key (file2.pem) should never be sent to the CA or shared; it remains securely stored on the requestor's server.
3. Certificate Issuance: After the CA signs the CSR, the resulting certificate can be used with the private key to establish secure communications.
A company uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server to authenticate managers on its AOS-CX switches. You want
to assign managers to groups on the AOS-CX switch by name.
How do you configure this setting in a CPPM TACACS+ enforcement profile?
To assign managers to groups on the AOS-CX switch by name using HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server, you should add the Aruba
service to the TACACS+ enforcement profile and set the Aruba-Admin-Role to the group name. This configuration ensures that the appropriate administrative roles are assigned to managers based on their group membership, allowing for role-based access control on the AOS-CX switches.
A company is implementing HPE Aruba Networking Wireless IDS/IPS (WIDS/WIPS) on its AOS-10 APs, which are managed in HPE Aruba Networking Central.
What is one requirement for enabling detection of rogue APs?
To enable the detection of rogue APs with HPE Aruba Networking Wireless IDS/IPS (WIDS/WIPS) on AOS-10 APs managed in HPE Aruba Networking Central, each AP must have a Foundation with Security license. This license enables advanced security features, including rogue AP detection, which is crucial for maintaining a secure wireless environment and protecting against unauthorized access points.
An admin has configured an AOS-CX switch with these settings:
port-access role employees
vlan access name employees
This switch is also configured with CPPM as its RADIUS server.
Which enforcement profile should you configure on CPPM to work with this configuration?
To ensure that the AOS-CX switch properly assigns the 'employees' role when using CPPM (ClearPass Policy Manager) as the RADIUS server, you should configure a RADIUS Enforcement profile on CPPM with the Aruba-User-Role VSA (Vendor-Specific Attribute) set to 'employees'. This configuration ensures that when an endpoint authenticates, CPPM sends the appropriate role assignment to the AOS-CX switch, which then applies the corresponding policies and VLAN settings defined for the 'employees' role.
A company has AOS-CX switches at the access layer, managed by HPE Aruba Networking Central. You have identified suspicious activity on a wired client. You want to analyze the client's traffic with Wireshark, which you have on your management station.
What should you do?
Why a Mirror Session Is the Correct Choice
To analyze a wired client's traffic with Wireshark, you need the traffic mirrored to your management station where Wireshark is installed. The most effective way to achieve this is by configuring a mirror session on the AOS-CX switch, specifying the client port as the source and your management station as the destination.
Analysis of Each Option
A . Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port:
Incorrect:
AOS-CX switches do not natively support packet capture (e.g., tcpdump) directly on the switch CLI.
This approach is not feasible for capturing and analyzing live client traffic.
B . Go to the client's switch in HPE Aruba Networking Central. Use the 'Security' page to run a packet capture:
Incorrect:
HPE Aruba Networking Central provides security insights but does not directly support initiating packet captures for detailed analysis.
Traffic analysis with tools like Wireshark requires local packet capture at the management station.
C . Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port:
Incorrect:
Captive portals are designed for user authentication and redirection, not traffic analysis.
This would disrupt the client's network activity without enabling traffic analysis in Wireshark.
D . Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination:
Correct:
Mirroring the client port to your management station is the standard method for analyzing live network traffic with Wireshark.
Steps include:
Configure a mirror session on the client's AOS-CX switch.
Set the client's port as the source.
Set your management station as the destination using its IP address (via GRE tunnel or physical interface).
Start capturing traffic with Wireshark on the management station.
Final Recommendation
To analyze the client's traffic, configure a mirror session on the switch, set the client port as the source, and direct the traffic to your management station where Wireshark is running.
