質問29
What is one way that WPA3-PerSonal enhances security when compared to WPA2-Personal?

WPA3-Perscn3i is more secure against password leaking Because all users nave their own username and password

WPA3-Personai prevents eavesdropping on other users’ wireless traffic by a user who knows the passphrase for the WLAN.

WPA3-Personai is more resistant to passphrase cracking Because it requires passphrases to be at least 12 characters

WPA3-Personal is more complicated to deploy because it requires a backend authentication server

質問30
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.

質問31
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.

質問32
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.

質問33
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.

質問34

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

WPA3-Personal and MAC-Auth

Captive portal and WPA3-Personai

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

質問35
How does the ArubaOS firewall determine which rules to apply to a specific client’s traffic?

The firewall applies the rules in policies associated with the client’s wlan

The firewall applies thee rules in policies associated with the client’s user role.

The firewall applies every rule that includes the client’s IP address as the source or destination.

質問36
What are the roles of 802.1X authenticators and authentication servers?

The authenticator stores the user account database, while the server stores access policies.

The authenticator supports only EAP, while the authentication server supports only RADIUS.

The authenticator is a RADIUS client and the authentication server is a RADIUS server.

The authenticator makes access decisions and the server communicates them to the supplicant.

質問37
What is one of the roles of the network access server (NAS) in the AAA framewonx?

It authenticates legitimate users and uses policies to determine which resources each user is allowed to access.

It negotiates with each user’s device to determine which EAP method is used for authentication

It enforces access to network services and sends accounting information to the AAA server

It determines which resources authenticated users are allowed to access and monitors each users session

質問38
What is a correct guideline for the management protocols that you should use on ArubaOS-Switches?

Disable Telnet and use TFTP instead.

Disable SSH and use https instead.

Disable Telnet and use SSH instead

Disable HTTPS and use SSH instead

質問39
You are deploying an Aruba Mobility Controller (MC). What is a best practice for setting up secure management access to the ArubaOS Web UP

Avoid using external manager authentication tor the Web UI.

Change the default 4343 port tor the web UI to TCP 443.

Install a CA-signed certificate to use for the Web UI server certificate.

Make sure to enable HTTPS for the Web UI and select the self-signed certificate Installed in the factory.

質問40
Which is a correct description of a stage in the Lockheed Martin kill chain?

In the delivery stage, malware collects valuable data and delivers or exfilltrated it to the hacker.

In the reconnaissance stage, the hacker assesses the impact of the attack and how much information was exfilltrated.

In the weaponization stage, which occurs after malware has been delivered to a system, the malware executes Its function.

In the exploitation and installation phases, malware creates a backdoor into the infected system for the hacker.

質問41
How should admins deal with vulnerabilities that they find in their systems?

They should apply fixes, such as patches, to close the vulnerability before a hacker exploits it.

They should add the vulnerability to their Common Vulnerabilities and Exposures (CVE).

They should classify the vulnerability as malware. a DoS attack or a phishing attack.

They should notify the security team as soon as possible that the network has already been breached.

質問42
What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial or service attack (DoS)?

A DDoS attack originates from external devices, while a DoS attack originates from internal devices

A DDoS attack is launched from multiple devices, while a DoS attack is launched from a single device

A DoS attack targets one server, a DDoS attack targets all the clients that use a server

A DDoS attack targets multiple devices, while a DoS Is designed to Incapacitate only one device

質問43
Which correctly describes a way to deploy certificates to end-user devices?

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

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

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

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

質問46
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
