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. configuring a PAPI key that matches on the APs and MCs
- D. approving the APs as authorized APs on the AP whitelist
Answer: D
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.
NEW QUESTION # 43 
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 failed to maintain a reliable connection, leading to a timeout error
- B. The client has passed 802 1X authentication and the authentication server did not send an Aruba-User-Role VSA
- 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 attempted 802 1X authentication, but the MC could not contact the authentication server
Answer: B
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.

NEW QUESTION # 48
A company has an ArubaOS controller-based solution with a WPA3-Enterprise WLAN. which authenticates wireless clients to Aruba ClearPass Policy Manager (CPPM). The company has decided to use digital certificates for authentication A user's Windows domain computer has had certificates installed on it However, the Networks and Connections window shows that authentication has tailed for the user. The Mobility Controllers (MC's) RADIUS events show that it is receiving Access-Rejects for the authentication attempt.
What is one place that you can you look for deeper insight into why this authentication attempt is failing?
- A. the RADIUS events within the CPPM Event Viewer
- B. the Alerts tab in the authentication record in CPPM Access Tracker
- C. the reports generated by Aruba ClearPass Insight
- D. the packets captured on the MC control plane destined to UDP 1812
Answer: B
NEW QUESTION # 49
What is a difference between radius and TACACS+?
- A. RADIUS combines the authentication and authorization process while TACACS+ separates them.
- B. RADIUS uses TCP for Its connection protocol, while TACACS+ uses UDP tor its connection protocol.
- C. RADIUS encrypts the complete packet, white TACACS+ only offers partial encryption.
- D. RADIUS uses Attribute Value Pairs (AVPs) in its messages, while TACACS+ does not use them.
Answer: A
Explanation:
RADIUS and TACACS+ are both protocols used for networking authentication, but they handle the processes of authentication and authorization differently. RADIUS (Remote Authentication Dial-In User Service) combines authentication and authorization into a single process, whereas TACACS+ (Terminal Access Controller Access-Control System Plus) separates these processes. This separation in TACACS+ allows more flexible policy enforcement and better control over commands a user can execute. This difference is well-documented in various network security resources, including Cisco's technical documentation and security protocol manuals.
NEW QUESTION # 50
What is a vulnerability of an unauthenticated Dime-Heliman exchange?
- A. A brute force attack can relatively quickly derive Diffie-Hellman private values if they are able to obtain public values
- B. A hacker can replace the public values exchanged by the legitimate peers and launch an MITM attack.
- C. Diffie-Hellman with elliptic curve values is no longer considered secure in modem networks, based on NIST recommendations.
- D. Participants must agree on a passphrase in advance, which can limit the usefulness of Diffie- Hell man in practical contexts.
Answer: B
NEW QUESTION # 51
How can ARP be used to launch attacks?
- A. Hackers can exploit the fact that the port used for ARP must remain open and thereby gain remote access to another user's device.
- B. A hacker can use ARP to claim ownership of a CA-signed certificate that actually belongs to another device.
- C. A hacker can send gratuitous ARP messages with the default gateway IP to cause devices to redirect traffic to the hacker's MAC address.
- D. Hackers can use ARP to change their NIC's MAC address so they can impersonate legiti-mate users.
Answer: C
Explanation:
ARP (Address Resolution Protocol) can indeed be exploited to conduct various types of attacks, most notably ARP spoofing/poisoning. Gratuitous ARP is a special kind of ARP message which is used by an IP node to announce or update its IP to MAC mapping to the entire network. A hacker can abuse this by sending out gratuitous ARP messages pretending to associate the IP address of the router (default gateway) with their own MAC address. This results in traffic that was supposed to go to the router being sent to the attacker instead, thus potentially enabling the attacker to intercept, modify, or block traffic.
NEW QUESTION # 52
What is a correct use case for using the specified certificate file format?
- A. using a PKCS12 file to install a certificate plus its private key on a device
- B. using a PKCS7 file to install a certificate plus and its private key on a device
- C. using a PEM file to install a binary encoded certificate on a device
- D. using a PKCS7 file to install a binary encoded private key on a device
Answer: A
Explanation:
The correct use case for using the specified certificate file format is option B, using a PKCS12 file to install a certificate along with its private key on a device. PKCS12 is a binary format for storing a certificate chain and private key in a single encrypted file. PEM files are Base64 encoded certificate files and are typically used for storing certificates, not private keys, and PKCS7 is used for certificate chains without the private key.
These answers are based on general networking and security practices, specifically within the context of Aruba network device configurations. If you have questions specific to Oracle Database 12c SQL, please provide the relevant details or ask separate questions related to that topic.

NEW QUESTION # 59
What is one difference between EAP-Tunneled Layer security (EAP-TLS) and Protected EAP (PEAP)?
- A. EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake.
- B. EAP-TLS creates a TLS tunnel for transmitting user credentials securely while PEAP protects user credentials with TKIP encryption.
- C. EAP-TLS requires the supplicant to authenticate with a certificate, hut PEAP allows the supplicant to use a username and password.
- D. EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of Its process
Answer: C
Explanation:
EAP-TLS and PEAP both provide secure authentication methods, but they differ in their requirements for client-side authentication. EAP-TLS requires both the client (supplicant) and the server to authenticate each other with certificates, thereby ensuring a very high level of security. On the other hand, PEAP requires a server-side certificate to create a secure tunnel and allows the client to authenticate using less stringent methods, such as a username and password, which are then protected by the tunnel. This makes PEAP more flexible in environments where client-side certificates are not feasible.References:

NEW QUESTION # 60
What is a correct guideline for the management protocols that you should use on ArubaOS-Switches?
- A. Disable SSH and use https instead.
- B. Disable HTTPS and use SSH instead
- C. Disable Telnet and use TFTP instead.
- D. Disable Telnet and use SSH instead
Answer: D
Explanation:
In managing ArubaOS-Switches, the best practice is to disable less secure protocols such as Telnet and use more secure alternatives like SSH (Secure Shell). SSH provides encrypted connections between network devices, which is critical for maintaining the security and integrity of network communications. This guideline is aligned with general security best practices that prioritize the use of protocols with strong, built-in encryption mechanisms to prevent unauthorized access and ensure data privacy.
NEW QUESTION # 61
You have been asked to rind logs related to port authentication on an ArubaOS-CX switch for events logged in the past several hours But. you are having trouble searching through the logs What is one approach that you can take to find the relevant logs?
- A. Enable debugging for "portaccess" to move the relevant logs to a buffer.
- B. Configure a logging Tiller for the "port-access" category, and apply that filter globally.
- C. Specify a logging facility that selects for "port-access" messages.
- D. Add the "-C and *-c port-access" options to the "show logging" command.
Answer: B
Explanation:
In ArubaOS-CX, managing and searching logs can be crucial for tracking and diagnosing issues related to network operations such as port authentication. To efficiently find logs related to port authentication, configuring a logging filter specifically for this category is highly effective.
Logging Filter Configuration: In ArubaOS-CX, you can configure logging filters to refine the logs that are collected and viewed. By setting up a filter for the "port-access" category, you focus the logging system to only capture and display entries related to port authentication events. This approach reduces the volume of log data to sift through, making it easier to identify relevant issues.
Global Application of Filter: Applying the filter globally ensures that all relevant log messages, regardless of their origin within the switch's modules or interfaces, are captured under the specified category. This global application is crucial for comprehensive monitoring across the entire device.
Alternative Options and Their Evaluation:
Option A: Adding "-C and *-c port-access" to the "show logging" command is not a standard command format in ArubaOS-CX for filtering logs directly through the show command.
Option C: Enabling debugging for "portaccess" indeed increases the detail of logs but primarily serves to provide real-time diagnostic information rather than filtering existing logs.
Option D: Specifying a logging facility focuses on routing logs to different destinations or subsystems and does not inherently filter by log category like port-access.
NEW QUESTION # 62
Refer to the exhibit.
How can you use the thumbprint?
- A. When you first connect to the switch with SSH from a management station, make sure that the thumbprint matches to ensure that a man-in-t he-mid die (MITM) attack is not occurring
- B. install this thumbprint on management stations the stations can then authenticate with the thumbprint instead of admins having to enter usernames and passwords.
- C. Copy the thumbprint to other Aruba switches to establish a consistent SSH Key for all switches this will enable managers to connect to the switches securely with less effort
- D. Install this thumbprint on management stations to use as two-factor authentication along with manager usernames and passwords, this will ensure managers connect from valid stations
Answer: A
Explanation:
The thumbprint (also known as a fingerprint) of a certificate or SSH key is a hash that uniquely represents the public key contained within. When you first connect to the switch with SSH from a management station, you should ensure that the thumbprint matches what you expect. This is a security measure to confirm the identity of the device you are connecting to and to ensure that a man-in-the-middle (MITM) attack is not occurring. If the thumbprint matches the known good thumbprint of the switch, it is safe to proceed with the connection.
References:
SSH and network security protocols that discuss the importance of verifying the identity of devices before initiating a secure connection.
IT security guides that provide best practices for avoiding MITM attacks during SSH sessions.
NEW QUESTION # 63
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 the certificate has a DNS SAN that matches arubapedia.arubanetworks.com
- B. It makes sure that the public key in the certificate matches a private key stored on DeviceA.
- C. It makes sure that the public key in the certificate matches DeviceA's private HTTPS key.
- D. It makes sure that the key in the certificate matches the key that DeviceA uses for HTTPS.
Answer: A
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 # 64
Refer to the exhibit.
This Aruba Mobility Controller (MC) should authenticate managers who access the Web Ul to ClearPass Policy Manager (CPPM) ClearPass admins have asked you to use RADIUS and explained that the MC should accept managers' roles in Aruba-Admin-Role VSAs Which setting should you change to follow Aruba best security practices?
- A. Clear the MSCHAP check box
- B. Change the default role to "guest-provisioning"
- C. Disable local authentication
- D. Change the local user role to read-only
Answer: C
Explanation:
For following Aruba best security practices, the setting you should change is to disable local authentication.
When integrating with an external RADIUS server like ClearPass Policy Manager (CPPM) for authenticating administrative access to the Mobility Controller (MC), it is a best practice to rely on the external server rather than the local user database. This practice not only centralizes the management of user roles and access but also enhances security by leveraging CPPM's advanced authentication mechanisms.
