NEW QUESTION # 93
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?
Answer: D
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.

NEW QUESTION # 94
You have been authorized to use containment to respond to rogue APs detected by ArubaOS Wireless Intrusion Prevention (WIP). What is a consideration for using tarpit containment versus traditional wireless containment?
Answer: C
Explanation:
Tarpit containment is a method used in ArubaOS Wireless Intrusion Prevention (WIP) to contain rogue APs. It differs from traditional wireless containment in several ways, particularly in how it interacts with clients and manages network resources.
Tarpit containment works by spoofing frames from an AP to confuse a client about its association. It forces the client to associate with a fake channel or BSSID, which is more efficient than rogue containment via repeated de-authorization requests. This method is designed to be less disruptive and more resource-efficient1.
Here's why the other options are not correct:
Option A is incorrect because tarpit containment does not involve sending ARP frames over the wired network. It operates wirelessly by creating a fake channel or BSSID.
Option B is incorrect because tarpit containment does not selectively target authorized clients; it affects all clients connected to the rogue AP.
Option C is incorrect because tarpit containment does require an RF Protect license to function2.
Therefore, Option D is the correct answer. Tarpit containment is more effective at keeping clients off the network with fewer disassociation frames than traditional wireless containment. It achieves this by forming associations with clients, which leads to a more efficient use of airtime and reduces the chance of negative effects on legitimate network users12.
NEW QUESTION # 95
What is one difference between EAP-Tunneled Layer security (EAP-TLS) and Protected EAP (PEAP)?
Answer: B
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 # 96
A company has Aruba Mobility Controllers (MCs), Aruba campus APs, and ArubaOS-Switches. The company plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type. This company is using only CPPM and no other ClearPass solutions.
The ClearPass admins tell you that they want to use HTTP User-Agent strings to help classify endpoints.
What should you do as a part of configuring the ArubaOS-Switches to support this requirement?
Answer: A
Explanation:
ArubaOS-Switches can use sFlow technology to sample network traffic and send the samples to a collector, such as ClearPass Policy Manager (CPPM), for analysis. sFlow can be configured to capture various types of traffic, including HTTP, which typically contains User-Agent strings that can be used for device fingerprinting and classification.
To support the requirement for using HTTP User-Agent strings to classify endpoints, the switches would need to be configured to send sFlow samples containing HTTP traffic to CPPM. CPPM would then analyze these samples and use the User-Agent strings to classify the devices.
Therefore, the correct action to configure ArubaOS-Switches would involve:
Configuring CPPM as the sFlow collector on the switches.
Enabling sFlow on the edge ports that connect to endpoints.
This approach allows the network traffic to be analyzed by CPPM without requiring any additional mirroring or redirection of traffic, which would be resource-intensive and potentially disruptive to network performance.
NEW QUESTION # 97
What is a guideline for managing local certificates on AOS-CX switches?
Answer: D
Explanation:
AOS-CX switches use certificates for various purposes, such as securing HTTPS access to the switch's web interface, authenticating the switch as a RadSec client, or securing other communications. Managing local certificates on AOS-CX switches involves ensuring that the switch trusts the certificate authority (CA) that issued the certificate, which is critical for proper operation.
Option C, "Before installing the local certificate, create a trust anchor (TA) profile with the root CA certificate for the certificate that you will install," is correct. A trust anchor (TA) profile on AOS-CX switches contains the root CA certificate (or intermediate CA certificate) that issued the local certificate. This TA profile allows the switch to validate the certificate chain when the local certificate is installed. For example, if you install a CA-signed certificate for the HTTPS server, the switch needs the root CA certificate in a TA profile to trust the certificate. This is a standard guideline for certificate management on AOS-CX switches to ensure secure and proper operation.
Option A, "Understand that the switch must use the same certificate for all usages, such as its HTTPS server and RadSec client," is incorrect. AOS-CX switches support using different certificates for different purposes. For example, you can have one certificate for the HTTPS server and another for RadSec client authentication, as long as each certificate is associated with the appropriate service and trusted by the switch.
Option B, "Create a self-signed certificate online on the switch because AOS-CX switches do not support CA-signed certificates," is incorrect. AOS-CX switches fully support CA-signed certificates, and using CA-signed certificates is recommended for production environments to ensure trust and security. Self-signed certificates can be used for testing but are not a guideline for general certificate management.
Option D, "Install an Online Certificate Status Protocol (OCSP) certificate to simplify the process of enrolling and re-enrolling for certificates," is incorrect. OCSP is a protocol used to check the revocation status of certificates, not to simplify certificate enrollment. AOS-CX switches support OCSP for certificate validation, but installing an "OCSP certificate" is not a concept in certificate management, and it's not a guideline for managing local certificates.
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"Before installing a CA-signed local certificate on the switch, you must create a trust anchor (TA) profile that includes the root CA certificate (or intermediate CA certificate) that issued the local certificate. This ensures that the switch can validate the certificate chain. For example, to install a CA-signed certificate for the HTTPS server, use the command crypto pki ta-profile <profile-name> to create the TA profile, and then import the root CA certificate into the profile using crypto pki import ta-profile <profile-name>. Then, install the local certificate using crypto pki import local-certificate <certificate-name> and associate it with the HTTPS server." (Page 201, Certificate Management Section) Additionally, the guide notes:
"AOS-CX switches support both self-signed and CA-signed certificates. For production environments, it is recommended to use CA-signed certificates and ensure that the appropriate trust anchor profiles are configured to validate the certificate chain." (Page 202, Best Practices Section)
