NEW QUESTION # 45
You configure an ArubaOS-Switch to enforce 802.1X authentication with ClearPass Policy Manager (CPPM) denned as the RADIUS server Clients cannot authenticate You check Aruba ClearPass Access Tracker and cannot find a record of the authentication attempt.
What are two possible problems that have this symptom? (Select two)
- A. The RADIUS shared secret does not match between the switch and CPPM.
- B. Clients are not configured to trust the root CA certificate for CPPM's RADIUS/EAP certificate.
- C. Clients are configured to use a mismatched EAP method from the one In the CPPM service.
- D. users are logging in with the wrong usernames and passwords or invalid certificates.
- E. CPPM does not have a network device defined for the switch's IP address.
Answer: A,E
Explanation:
If clients cannot authenticate and there is no record of the authentication attempt in Aruba ClearPass Access Tracker, two possible problems that could cause this symptom are:
The RADIUS shared secret does not match between the switch and CPPM. This mismatch would prevent the switch and CPPM from successfully communicating, so authentication attempts would fail, and no record would appear in Access Tracker.
CPPM does not have a network device profile defined for the switch's IP address. Without a network device profile, CPPM would not recognize authentication attempts coming from the switch and would not process them, resulting in no logs in Access Tracker.
The other options are incorrect because:
Users logging in with the wrong credentials would still generate an attempt record in Access Tracker.
Clients configured to use a mismatched EAP method would also generate an attempt record in Access Tracker.
Clients not configured to trust the root CA certificate for CPPM's RADIUS/EAP certificate might fail authentication, but the attempt would still be logged in Access Tracker.

Refer to the exhibit.
You need to ensure that only management stations in subnet 192.168.1.0/24 can access the ArubaOS-Switches' CLI. Web Ul. and REST interfaces The company also wants to let managers use these stations to access other parts of the network What should you do?
- A. Configure the switch to listen for these protocols on OOBM only.
- B. Specify vlan 100 as the management vlan for the switches.
- C. Specify 192.168.1.0.255.255.255.0 as authorized IP manager address
- D. Establish a Control Plane Policing class that selects traffic from 192.168 1.0/24.
Answer: C
Explanation:
To ensure that only management stations in the subnet 192.168.1.0/24 can access the ArubaOS-Switches' Command Line Interface (CLI), Web UI, and REST interfaces, while also allowing managers to access other parts of the network, you should specify 192.168.1.0 255.255.255.0 as the authorized manager IP address on the switches. This configuration will restrict access to the switch management interfaces to devices within the specified IP address range, effectively creating a management access list.

- B. WPA3-Personai is more resistant to passphrase cracking Because it requires passphrases to be at least 12 characters
- C. WPA3-Perscn3i is more secure against password leaking Because all users nave their own username and password
- D. WPA3-Personal is more complicated to deploy because it requires a backend authentication server
Answer: C
NEW QUESTION # 48
What is a correct guideline for the management protocols that you should use on ArubaOS-Switches?
- A. Disable Telnet and use SSH instead
- B. Disable Telnet and use TFTP instead.
- C. Disable HTTPS and use SSH instead
- D. Disable SSH and use https instead.
Answer: A
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 # 49
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 binary encoded private key on a device
- C. using a PKCS7 file to install a certificate plus and its private key on a device
- D. using a PEM file to install a binary encoded certificate 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 # 50

- A. 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.
- B. 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.
- C. it uses a combination or software and hardware to jam the RF band and prevent the client from connecting to any wireless networks
- D. it examines wireless clients' probes and broadcasts the SSlDs in the probes, so that wireless clients will connect to it automatically.
Answer: A
NEW QUESTION # 51
What is a consideration for implementing wireless containment in response to unauthorized devices discovered by ArubaOS Wireless Intrusion Detection (WIP)?
- A. Wireless containment only works against unauthorized wireless devices that connect to your corporate LAN, so it does not offer protection against Interfering APs.
- B. It is best practice to implement automatic containment of unauthorized devices to eliminate the need to locate and remove them.
- C. Your company should consider legal implications before you enable automatic containment or implement manual containment.
- D. Because wireless containment has a lower risk of targeting legitimate neighbors than wired containment, it is recommended in most use cases.
Answer: C
Explanation:
When implementing wireless containment as a response to unauthorized devices, a company should consider the legal implications. Wireless containment might affect devices that are not part of the company's network and could be considered as a form of interference. This could have legal consequences, and therefore, such actions should be carefully reviewed and ideally should be performed in a targeted and controlled manner, reducing the risk of legal issues.
NEW QUESTION # 52
What is a guideline for deploying Aruba ClearPass Device Insight?
- A. For companies with multiple sites, deploy a pair of Device Insight Collectors at the HQ or the central data center.
- B. Configure remote mirroring on access layer Aruba switches, using Device Insight Analyzer as the destination IP.
- C. Deploy a Device Insight Collector at every site in the corporate WAN to reduce the impact on WAN links.
- D. Make sure that Aruba devices trust the root CA certificate for the ClearPass Device Insight Analyzer's HTTPS certificate.
Answer: A
Explanation:
For deploying Aruba ClearPass Device Insight effectively, especially in environments with multiple sites, it is recommended to deploy a pair of Device Insight Collectors at the headquarters or the central data center.
This deployment strategy helps in centralizing the data collection and analysis, which simplifies management and enhances performance by reducing the data load on the WAN links connecting different sites.
Centralizing the collectors at a major site or data center allows for better scalability and reliability of the network management system. This configuration also aids in achieving a more consistent and comprehensive monitoring and analysis of the devices across the network, ensuring that the security and management policies are uniformly applied. This recommendation is based on best practices for network architecture design, particularly those discussed in Aruba's deployment guides and network management strategies.
NEW QUESTION # 53
Which is a use case for enabling Control Plane Policing on Aruba switches?
- A. to prevent the switch from accepting routing updates from unauthorized users
- B. to encrypt traffic between tunneled node switches and Mobility Controllers (MCs)
- C. to mitigate Denial of Service (Dos) attacks on the switch
- D. to prevent unauthorized network devices from sending routing updates
Answer: C
Explanation:
Control Plane Policing (CoPP) on Aruba switches is used to mitigate Denial of Service (DoS) attacks on the switch. CoPP allows network administrators to restrict the impact of control plane traffic on the switch's CPU, thereby protecting network stability and integrity. By setting rate limits and specifying allowed traffic types, administrators can prevent malicious or malformed packets from overwhelming the switch's control plane, which could otherwise lead to a DoS condition and potentially disrupt network operations. This use case of CoPP is detailed in Aruba's network management documentation, where best practices and configurations to protect against DoS attacks are discussed.
NEW QUESTION # 54
Which correctly describes a way to deploy certificates to end-user devices?
- A. ClearPass OnGuard can help to deploy certificates to end-user devices, whether or not they are members of a Windows domain
- B. ClearPass Device Insight can automatically discover end-user devices and deploy the proper certificates to them
- C. ClearPass Onboard can help to deploy certificates to end-user devices, whether or not they are members of a Windows domain
- D. in a Windows domain, domain group policy objects (GPOs) can automatically install computer, but not user certificates
Answer: C
Explanation:
ClearPass Onboard is part of the Aruba ClearPass suite and it provides a mechanism to deploy certificates to end-user devices, regardless of whether or not they are members of a Windows domain. ClearPass Onboard facilitates the configuration and provisioning of network settings and security, including the delivery and installation of certificates to ensure secure network access. This capability enables a bring-your-own-device (BYOD) environment where devices can be securely managed and provided with the necessary certificates for network authentication.
NEW QUESTION # 55
Refer to the exhibit.
You are deploying a new ArubaOS Mobility Controller (MC), which is enforcing authentication to Aruba ClearPass Policy Manager (CPPM). The authentication is not working correctly, and you find the error shown In the exhibit in the CPPM Event Viewer.
What should you check?
- A. that the MC has valid admin credentials configured on it for logging into the CPPM
- B. that the MC has been added as a domain machine on the Active Directory domain with which CPPM is synchronized
- C. that the IP address that the MC is using to reach CPPM matches the one defined for the device on CPPM
- D. that the snared secret configured for the CPPM authentication server matches the one defined for the device on CPPM
Answer: C
Explanation:
Given the error message from the ClearPass Policy Manager (CPPM) Event Viewer, indicating a RADIUS authentication attempt from an unknown Network Access Device (NAD), you should check that the IP address the Mobility Controller (MC) is using to communicate with CPPM matches the IP address defined for the MC in the CPPM's device inventory. If there is a mismatch in IP addresses, CPPM will not recognize the MC as a known device and will not process the authentication request, leading to the error observed.

NEW QUESTION # 56 
A company has an Aruba Instant AP cluster. A Windows 10 client is attempting to connect a WLAN that enforces WPA3-Enterprise with authentication to ClearPass Policy Manager (CPPM). CPPM is configured to require EAP-TLS. The client authentication fails. In the record for this client's authentication attempt on CPPM, you see this alert.
What is one thing that you check to resolve this issue?
- A. whether the client has a valid certificate installed on it to let it support EAP-TLS
- B. whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster
- C. whether the client has a third-party 802.1 X supplicant, as Windows 10 does not support EAP-TLS
- D. whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster
Answer: A
Explanation:
In the context of WPA3-Enterprise with EAP-TLS authentication, the error message "Client doesn't support configured EAP methods" suggests that the client is not able to complete the EAP-TLS authentication process. EAP-TLS requires that both the server (in this case, CPPM) and the client have a valid certificate for mutual authentication. Windows 10 does support EAP-TLS natively, so options A, C, and D can be ruled out.
The most likely reason for the authentication failure is that the client device does not have the correct client certificate installed, which is required to establish a TLS session with the server. Therefore, ensuring that the client has a valid certificate installed that matches the server's requirements is the correct step to resolve this issue.
NEW QUESTION # 57

- B. Make sure that the UBT client vlan is assigned to the interface on which the switches reach the MC and only that interface.
- C. Configure a long, random PAPI security key that matches on the switches and the MC.
- D. install certificates on the switches, and make sure that CPsec is enabled on the MC
Answer: D
NEW QUESTION # 61
Which scenario requires the Aruba Mobility Controller to use a Server Certificate?
- 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 # 62
What is a benefit or using network aliases in ArubaOS firewall policies?
- A. You can use the aliases to conceal the true IP addresses of servers from potentially untrusted clients.
- B. You can use the aliases to translate client IP addresses to other IP addresses on the other side of the firewall
- C. You can adjust the IP addresses in the aliases, and the rules using those aliases automatically update
- D. You can associate a reputation score with the network alias to create rules that filler traffic based on reputation rather than IP.
Answer: D
NEW QUESTION # 63
You have been instructed to look in the ArubaOS Security Dashboard's client list Your goal is to find clients mat belong to the company and have connected to devices that might belong to hackers Which client fits this description?
- A. MAC address d8:50:e6:f3;TO;ab; Client Classification Interfering. AP Classification Rogue
- B. MAC address d8:50:e6:f3;6d;a4; Client Classification Authorized; AP Classification, interfering
- C. MAC address d8:50:e6:f3;6e;60; Client Classification Interfering. AP Classification Interfering
- D. MAC address d8:50:e6 f3;6e;c5; Client Classification Interfering. AP Classification Neighbor
Answer: A
Explanation:
In the context of the ArubaOS Security Dashboard, if the goal is to find company clients that have connected to devices potentially operated by hackers, you would look for a client that is classified as 'Interfering' (indicating a security threat) while being connected to an 'AP Classification: Rogue'. A rogue AP is one that is not under the control of network administrators and is considered malicious or a security threat. Therefore, the client fitting this description is:
MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Rogue
NEW QUESTION # 64
You need to implement a WPA3-Enterprise network that can also support WPA2-Enterprise clients. What is a valid configuration for the WPA3-Enterprise WLAN?
- A. CNSA mode disabled with 256-bit keys
- B. CNSA mode disabled with 128-bit keys
- C. CNSA mode enabled with 128-bit keys
- D. CNSA mode enabled with 256-bit keys
Answer: A
Explanation:
In an Aruba network, when setting up a WPA3-Enterprise network that also supports WPA2-Enterprise clients, you would typically configure the network to operate in a transitional mode that supports both protocols. CNSA (Commercial National Security Algorithm) mode is intended for networks that require higher security standards as specified by the US National Security Agency (NSA). However, for compatibility with WPA2 clients, which do not support CNSA requirements, you would disable CNSA mode. WPA3 can use 256-bit encryption keys, which offer a higher level of security than the 128-bit keys used in WPA2.

- A. installing self-signed certificates on the APs
- B. approving the APs as authorized APs on the AP whitelist
- C. installing CA-signed certificates on the APs
- D. configuring a PAPI key that matches on the APs and MCs
Answer: B
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 # 66
The first exhibit shows roles on the MC, listed in alphabetic order. The second and third exhibits show the configuration for a WLAN to which a client connects. Which description of the role assigned to a user under various circumstances is correct?
- A. A user authenticates successfully with 802.1 X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employeel." The client's role is "guest."
- B. A user authenticates successfully with 802.1X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employee." The client's role is "guest."
- C. A user fails 802.1X authentication. The client remains connected, but is assigned the "guest" role.
- D. A user authenticates successfully with 802.1X, and the RADIUS Access-Accept includes an Aruba-User-RoleVSA set to "employeel." The client's role is "employeel."
Answer: D
Explanation:
In a WLAN setup that uses 802.1X for authentication, the role assigned to a user is determined by the result of the authentication process. When a user successfully authenticates via 802.1X, the RADIUS server may include a Vendor-Specific Attribute (VSA), such as the Aruba-User-Role, in the Access-Accept message.
This attribute specifies the role that should be assigned to the user. If the RADIUS Access-Accept message includes an Aruba-User-Role VSA set to "employee1", the client should be assigned the "employee1" role, as per the VSA, and not the default "guest" role. The "guest" role would typically be a fallback if no other role is specified or if the authentication fails.
NEW QUESTION # 67
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. Add the "-C and *-c port-access" options to the "show logging" command.
- C. Configure a logging Tiller for the "port-access" category, and apply that filter globally.
- D. Specify a logging facility that selects for "port-access" messages.
Answer: C
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 # 68
What is the purpose of an Enrollment over Secure Transport (EST) server?
- A. It provides a secure central repository for private keys associated with devices' digital certif-icates.
- B. It acts as an intermediate Certification Authority (CA) that signs end-entity certificates.
- C. It helps admins to avoid expired certificates with less management effort.
- D. It provides a more secure alternative to private CAs at less cost than a public CA.
Answer: C
Explanation:
EST (Enrollment over Secure Transport) is a protocol designed to streamline the certificate management process. It enables automated and secure enrollment, renewal, and revocation of digital certificates, which significantly reduces the management overhead typically associated with digital certificates. With EST, administrators can more easily manage certificates' lifecycle, ensuring that expired certificates are promptly replaced or renewed without significant manual intervention.
