  • B. In WPA3-Enterprise, the PMK is unique per session and derived using Simultaneous Authentication of Equals.
  • C. In WPA3-Personal, the PMK is derived directly from the passphrase and is the same tor every session.
  • D. In WPA3-Personal, the PMK is unique per session and derived using Simultaneous Authentication of Equals.

NEW QUESTION # 58
Device A is contacting https://arubapedia.arubanetworks.com. The web server sends a certificate chain. What does the browser do as part of validating the web server certificate?

  • A. It makes sure that the key in the certificate matches the key that DeviceA uses for HTTPS.
  • B. It makes sure that the public key in the certificate matches a private key stored on DeviceA.
  • C. It makes sure the certificate has a DNS SAN that matches arubapedia.arubanetworks.com
  • D. It makes sure that the public key in the certificate matches DeviceA's private HTTPS key.

Answer: C

Explanation:
When a device like Device A contacts a secure website and receives a certificate chain from the server, the browser's primary task is to validate the web server's certificate to ensure it is trustworthy. Part of this validation includes checking that the certificate contains a DNS Subject Alternative Name (SAN) that matches the domain name of the website being accessed-in this case, arubapedia.arubanetworks.com. This ensures that the certificate was indeed issued to the entity operating the domain and helps prevent man-in-the-middle attacks where an invalid certificate could be presented by an attacker. The DNS SAN check is critical because it directly ties the digital certificate to the domain it secures, confirming the authenticity of the website to the user's browser.


NEW QUESTION # 59
You are troubleshooting an authentication issue for Aruba switches that enforce 802 IX10 a cluster of Aruba ClearPass Policy Manager (CPPMs) You know that CPPM Is receiving and processing the authentication requests because the Aruba switches are showing Access-Rejects in their statistics However, you cannot find the record tor the Access-Rejects in CPPM Access Tracker What is something you can do to look for the records?

  • A. Go to the CPPM Event Viewer, because this is where RADIUS Access Rejects are stored.
  • B. Click Edit in Access viewer and make sure that the correct servers are selected.
  • C. Verify that you are logged in to the CPPM Ul with read-write, not read-only, access
  • D. Make sure that CPPM cluster settings are configured to show Access-Rejects

Answer: D


NEW QUESTION # 60
What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial or service attack (DoS)?

  • A. A DDoS attack is launched from multiple devices, while a DoS attack is launched from a single device
  • B. A DoS attack targets one server, a DDoS attack targets all the clients that use a server
  • 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: A

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 # 61
You have an HPE Aruba Networking Mobility Controller (MC) that is locked in a closet. What is another step that HPE Aruba Networking recommends to protect the MC from unauthorized access?

  • A. Disable local authentication of administrators entirely.
  • B. Use local authentication rather than external authentication to authenticate admins.
  • C. Set the local admin password to a long random value that is unknown or locked up securely.
  • D. Change the password recovery password.

Answer: C

Explanation:
The scenario involves an HPE Aruba Networking Mobility Controller (MC) that is physically secured in a locked closet, which provides protection against physical tampering. However, additional steps are needed to protect the MC from unauthorized access, particularly through administrative interfaces (e.g., SSH, web UI, console).
Option A, "Set the local admin password to a long random value that is unknown or locked up securely," is correct. HPE Aruba Networking recommends securing administrative access to the MC by setting a strong, random password for the local admin account (e.g., the default "admin" user). The password should be long (e.g., 16+ characters), random, and stored securely (e.g., in a password manager or safe). This ensures that even if an attacker gains physical access to the MC (e.g., by bypassing the locked closet) or attempts remote access, they cannot easily guess or brute-force the password.
Option B, "Disable local authentication of administrators entirely," is incorrect. Disabling local authentication entirely would prevent any fallback access to the MC if external authentication (e.g., RADIUS, TACACS+) fails. HPE Aruba Networking recommends maintaining a local admin account as a backup, but securing it with a strong password.
Option C, "Change the password recovery password," is incorrect. AOS-8 Mobility Controllers do not have a specific "password recovery password." Password recovery typically involves physical access to the device (e.g., via the console port) and a factory reset, which would be mitigated by the locked closet. This option is not a standard recommendation for securing the MC.
Option D, "Use local authentication rather than external authentication to authenticate admins," is incorrect. HPE Aruba Networking recommends using external authentication (e.g., RADIUS or TACACS+) for centralized management and stronger security (e.g., two-factor authentication). Local authentication should be a fallback, not the primary method, and it must be secured with a strong password.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"To protect the Mobility Controller from unauthorized access, even if it is physically secured in a locked closet, set the local admin password to a long, random value that is unknown or locked up securely. For example, use a password of at least 16 characters generated by a password manager, and store it in a secure location (e.g., a safe). This ensures that the local admin account, which is used as a fallback, is protected against unauthorized access attempts." (Page 385, Securing Administrative Access Section) Additionally, the HPE Aruba Networking Security Best Practices Guide notes:
"A recommended step to secure the Mobility Controller is to set a strong, random password for the local admin account. The password should be long (e.g., 16+ characters), randomly generated, and stored securely to prevent unauthorized access, even if the device is physically protected in a locked closet."
