it permits both of the packets

It drops the packet to 10.1.10.10 and permits the packet to 203.0.13.5.

NO.22 You have deployed a new Aruba Mobility Controller (MC) and campus APs (CAPs). One of the WLANs enforces 802.IX authentication lo Aruba ClearPass Policy Manager {CPPM) When you test connecting the client to the WLAN. the test falls You check Aruba ClearPass Access Tracker and cannot find a record of the authentication attempt You ping from the MC to CPPM. and the ping is successful.
What is a good next step for troubleshooting?

Renew CPPM’s RADIUS/EAP certificate

Reset the user credentials

Check CPPM Event viewer.

Check connectivity between CPPM and a backend directory server

NO.23 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?

Change the local user role to read-only

Clear the MSCHAP check box

Disable local authentication

Change the default role to “guest-provisioning”

NO.24 What correctly describes the Pairwise Master Key (PMK) in thee specified wireless security protocol?

In WPA3-Enterprise, the PMK is unique per session and derived using Simultaneous Authentication of Equals.

In WPA3-Personal, the PMK is unique per session and derived using Simultaneous Authentication of Equals.

In WPA3-Personal, the PMK is derived directly from the passphrase and is the same tor every session.

In WPA3-Personal, the PMK is the same for each session and is communicated to clients that authenticate

NO.25 What is a vulnerability of an unauthenticated Dime-Heliman exchange?

A hacker can replace the public values exchanged by the legitimate peers and launch an MITM attack.

A brute force attack can relatively quickly derive Diffie-Hellman private values if they are able to obtain public values

Diffie-Hellman with elliptic curve values is no longer considered secure in modem networks, based on NIST recommendations.

Participants must agree on a passphrase in advance, which can limit the usefulness of Diffie- Hell man in practical contexts.

NO.26 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?

Make sure that CPPM cluster settings are configured to show Access-Rejects

Verify that you are logged in to the CPPM Ul with read-write, not read-only, access

Click Edit in Access viewer and make sure that the correct servers are selected.

Go to the CPPM Event Viewer, because this is where RADIUS Access Rejects are stored.

NO.27 What is a reason to set up a packet capture on an Aruba Mobility Controller (MC)?

The company wants to use ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC.

The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely.

You want the MC to analyze wireless clients’ traffic at a lower level, so that the ArubaOS firewall can control the traffic I based on application.

You want the MC to analyze wireless clients’ traffic at a lower level, so that the ArubaOS firewall can control Web traffic based on the destination URL.

NO.28 What is one difference between EAP-Tunneled Layer security (EAP-TLS) and Protected EAP (PEAP)?

EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake.

EAP-TLS requires the supplicant to authenticate with a certificate, hut PEAP allows the supplicant to use a username and password.

EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of Its process

EAP-TLS creates a TLS tunnel for transmitting user credentials securely while PEAP protects user credentials with TKIP encryption.

NO.29 What is a guideline for creating certificate signing requests (CSRs) and deploying server Certificates on ArubaOS Mobility Controllers (MCs)?

Create the CSR online using the MC Web Ul if your company requires you to archive the private key.

if you create the CSR and public/private Keypair offline, create a matching private key online on the MC.

Create the CSR and public/private keypair offline If you want to install the same certificate on multiple MCs.

Generate the private key online, but the public key and CSR offline, to install the same certificate on multiple MCs.

NO.30 Refer to the exhibit.
