NEW QUESTION # 33
What is an example or phishing?

A. An attacker lures clients to connect to a software-based AP that is using a legitimate SSID.
B. An attacker sends emails posing as a service team member to get users to disclose their passwords.
C. An attacker checks a user's password by using trying millions of potential passwords.
D. An attacker sends TCP messages to many different ports to discover which ports are open.

Answer: B

Explanation:
Phishing is a type of social engineering attack where an attacker impersonates a trusted entity to deceive people into providing sensitive information, such as passwords or credit card numbers. An example of phishing is when an attacker sends emails posing as a service team member or a legitimate organization with the intention of getting users to disclose their passwords or other confidential information. These emails often contain links to fake websites that look remarkably similar to legitimate ones, tricking users into entering their details.References:

NEW QUESTION # 34
An AOS-CX switch currently has no device fingerprinting settings configured on it. You want the switch to start collecting DHCP and LLDP information. You enter these commands:
Switch(config)# client device-fingerprint profile myprofile
Switch(myprofile)# dhcp
Switch(myprofile)# lldp
What else must you do to allow the switch to collect information from clients?

A. Apply the policy to edge ports
B. Configure the switch as a DHCP relay
C. Add at least one LLDP option to the policy
D. Add at least one DHCP option to the policy

Answer: A

Explanation:
Device fingerprinting on an AOS-CX switch allows the switch to collect information about connected clients to aid in profiling and policy enforcement, often in conjunction with a solution like ClearPass Policy Manager (CPPM). The commands provided create a device fingerprinting profile named "myprofile" and enable the collection of DHCP and LLDP information:
client device-fingerprint profile myprofile: Creates a fingerprinting profile.
dhcp: Enables the collection of DHCP information (e.g., DHCP options like Option 55 for fingerprinting).
lldp: Enables the collection of LLDP (Link Layer Discovery Protocol) information (e.g., system name, description).
However, creating the profile and enabling DHCP and LLDP collection is not enough for the switch to start collecting this information from clients. The profile must be applied to the interfaces (ports) where clients are connected.
Option C, "Apply the policy to edge ports," is correct. In AOS-CX, the device fingerprinting profile must be applied to the edge ports (ports where clients connect) to enable the switch to collect DHCP and LLDP information from those clients. This is done using the command client device-fingerprint profile <profile-name> under the interface configuration. For example, on port 1/1/1, you would enter:
text
CollapseWrapCopy
Switch(config)# interface 1/1/1
Switch(config-if)# client device-fingerprint profile myprofile
This ensures that the switch collects DHCP and LLDP data from clients connected to the specified ports.
Option A, "Configure the switch as a DHCP relay," is incorrect. While a DHCP relay (using the ip helper-address command) is needed if the DHCP server is on a different subnet, it is not a requirement for the switch to collect DHCP information for fingerprinting. The switch can snoop DHCP traffic on the local VLAN without being a relay, as long as the profile is applied to the ports.
Option B, "Add at least one LLDP option to the policy," is incorrect. The lldp command in the fingerprinting profile already enables the collection of LLDP information. There is no need to specify individual LLDP options (e.g., system name, description) in the profile; the switch collects all available LLDP data by default.
Option D, "Add at least one DHCP option to the policy," is incorrect. The dhcp command in the fingerprinting profile already enables the collection of DHCP information, including options like Option 55 (Parameter Request List), which is commonly used for fingerprinting. There is no need to specify individual DHCP options in the profile.
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"To enable device fingerprinting on an AOS-CX switch, create a device fingerprinting profile using the client device-fingerprint profile <name> command, and specify the protocols to collect, such as dhcp for DHCP information and lldp for LLDP information. To start collecting data from clients, apply the profile to edge ports where clients connect using the command client device-fingerprint profile <name> under the interface configuration. For example, interface 1/1/1 followed by client device-fingerprint profile myprofile enables fingerprinting on port 1/1/1." (Page 160, Device Fingerprinting Configuration Section) Additionally, the HPE Aruba Networking AOS-CX 10.12 System Management Guide notes:
"The device fingerprinting profile must be applied to the ports where clients are connected to collect DHCP and LLDP information. The dhcp and lldp commands in the profile enable the collection of all relevant data for those protocols, such as DHCP Option 55 for fingerprinting, without requiring additional options to be specified."

NEW QUESTION # 35
You have configured a WLAN to use Enterprise security with the WPA3 version.
How does the WLAN handle encryption?

A. Traffic is encrypted with TKIP and keys derived from a unique PMK per client.
B. Traffic is encrypted with AES and keys derived from a PMK shared by all clients on the WLAN.
C. Traffic is encrypted with TKIP and keys derived from a PMK shared by all clients on the WLAN.
D. Traffic is encrypted with AES and keys derived from a unique PMK per client.

Answer: D

Explanation:
WPA3-Enterprise is a security protocol introduced to enhance the security of wireless networks, particularly in enterprise environments. It builds on the foundation of WPA2 but introduces stronger encryption and key management practices. In WPA3-Enterprise, authentication is typically performed using 802.1X, and encryption is handled using the Advanced Encryption Standard (AES).
WPA3-Enterprise Encryption: WPA3-Enterprise uses AES with the Galois/Counter Mode Protocol (GCMP) or Cipher Block Chaining Message Authentication Code Protocol (CCMP), both of which are AES-based encryption methods. WPA3 does not use TKIP (Temporal Key Integrity Protocol), which is a legacy encryption method used in WPA and early WPA2 deployments and is considered insecure.
Pairwise Master Key (PMK): In WPA3-Enterprise, the PMK is derived during the 802.1X authentication process (e.g., via EAP-TLS or EAP-TTLS). Each client authenticates individually with the authentication server (e.g., ClearPass), resulting in a unique PMK for each client. This PMK is then used to derive session keys (Pairwise Transient Keys, PTKs) for encrypting the client's traffic, ensuring that each client's traffic is encrypted with unique keys.
Option A, "Traffic is encrypted with TKIP and keys derived from a PMK shared by all clients on the WLAN," is incorrect because WPA3 does not use TKIP (it uses AES), and the PMK is not shared among clients in WPA3-Enterprise; each client has a unique PMK.
Option B, "Traffic is encrypted with TKIP and keys derived from a unique PMK per client," is incorrect because WPA3 does not use TKIP; it uses AES.
Option C, "Traffic is encrypted with AES and keys derived from a PMK shared by all clients on the WLAN," is incorrect because, in WPA3-Enterprise, the PMK is unique per client, not shared.
Option D, "Traffic is encrypted with AES and keys derived from a unique PMK per client," is correct. WPA3-Enterprise uses AES for encryption, and each client derives a unique PMK during 802.1X authentication, which is used to generate unique session keys for encryption.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"WPA3-Enterprise enhances security by using AES encryption with GCMP or CCMP. In WPA3-Enterprise mode, each client authenticates via 802.1X, resulting in a unique Pairwise Master Key (PMK) for each client. The PMK is used to derive session keys (Pairwise Transient Keys, PTKs) that encrypt the client's traffic with AES, ensuring that each client's traffic is protected with unique keys. WPA3 does not support TKIP, which is a legacy encryption method." (Page 285, WPA3-Enterprise Security Section) Additionally, the HPE Aruba Networking Wireless Security Guide notes:
"WPA3-Enterprise requires 802.1X authentication, which generates a unique PMK for each client. This PMK is used to derive AES-based session keys, providing individualized encryption for each client's traffic and eliminating the risks associated with shared keys."

NEW QUESTION # 36
What is a benefit of Protected Management Frames (PMF). sometimes called Management Frame Protection (MFP)?

A. PMF protects clients from DoS attacks based on forged de-authentication frames
B. PMF helps to protect APs and MCs from unauthorized management access by hackers.
C. PMF prevents hackers from capturing the traffic between APs and Mobility Controllers.
D. PMF ensures trial traffic between APs and Mobility Controllers (MCs) is encrypted.

Answer: A

Explanation:
Protected Management Frames (PMF), also known as Management Frame Protection (MFP), is designed to protect clients from denial-of-service (DoS) attacks that involve forged de-authentication and disassociation frames. These attacks can disconnect legitimate clients from the network. PMF provides a way to authenticate these management frames, ensuring that they are not forged, thus enhancing the security of the wireless network.
References:
IEEE 802.11w amendment, which introduces PMF as a security enhancement to protect management frames.
Wi-Fi Alliance security guidelines for Protected Management Frames (PMF).

NEW QUESTION # 37
What is symmetric encryption?

A. It simultaneously creates ciphertext and a same-size MAC.
B. It uses the same key to encrypt plaintext as to decrypt ciphertext.
C. It any form of encryption mat ensures that thee ciphertext Is the same length as the plaintext.
D. It uses a Key that is double the size of the message which it encrypts.

Answer: B

Explanation:
Symmetric encryption is a type of encryption where the same key is used to encrypt and decrypt the message.
It's called "symmetric" because the key used for encryption is identical to the key used for decryption. The data, or plaintext, is transformed into ciphertext during encryption, and then the same key is used to revert the ciphertext back to plaintext during decryption. It is a straightforward method but requires secure handling and exchange of the encryption key.References:
Basic principles of cryptography.
