Question 16

What is a vulnerability of an unauthenticated Dime-Heliman exchange?

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

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

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

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

Question 17

You have an Aruba Mobility Controller (MC). for which you are already using Aruba ClearPass Policy Manager (CPPM) to authenticate access to the Web Ul with usernames and passwords You now want to enable managers to use certificates to log in to the Web Ul CPPM will continue to act as the external server to check the names in managers' certificates and tell the MC the managers' correct rote in addition to enabling certificate authentication. what is a step that you should complete on the MC?

A.Verify that the MC trusts CPPM's HTTPS certificate by uploading a trusted CA certificate Also, configure a CPPM username and password on the MC

B.Verify that the MC has the correct certificates, and add RadSec to the RADIUS server configuration for CPPM

C.install all of the managers' certificates on the MC as OCSP Responder certificates

D.Create a local admin account mat uses certificates in the account, specify the correct trusted CA certificate and external authentication

Question 18

What is symmetric encryption?

A.It simultaneously creates ciphertext and a same-size MAC.

B.It uses a Key that is double the size of the message which it encrypts.

C.It uses the same key to encrypt plaintext as to decrypt ciphertext.

D.It any form of encryption mat ensures that thee ciphertext Is the same length as the plaintext.

Question 19

The company also wants to provide encryption for the network for devices mat are capable, you implement Tor the WLAN?
Which security options should

A.WPA3-Personal and MAC-Auth

B.Captive portal and WPA3-Personai

C.Captive portal and Opportunistic Wireless Encryption (OWE) in transition mode

D.Opportunistic Wireless Encryption (OWE) and WPA3-Personal

Question 20

Which correctly describes a way to deploy certificates to end-user devices?

A.ClearPass Onboard can help to deploy certificates to end-user devices, whether or not they are members of a Windows domain

B.ClearPass OnGuard can help to deploy certificates to end-user devices, whether or not they are members of a Windows domain

C.in a Windows domain, domain group policy objects (GPOs) can automatically install computer, but not user certificates

D.ClearPass Device Insight can automatically discover end-user devices and deploy the proper certificates to them
