Exam N10-008 topic 1 question 322 discussion

WEP – RC4 WPA – TKIP WPA2 – AES

WPA uses TKIP, WPA2 uses AES for encryption Anthony Sequeira "WPA uses Temporal Key Integrity Protocol (TKIP) for enhanced encryption. TKIP uses RC4 for the encryption algorithm, and the CompTIA Network+ exam may reference TKIP-RC4 in a discussion of wireless." " WPA2 uses Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) for integrity checking and Advanced Encryption Standard (AES) for encryption. On the Network+ exam, you might find this referenced as simply CCMP-AES"

these questions are making me delusional. questioning everything. I went to my router to check WPA2 supports both AES and TKIP. so it should be an answer here. but I have to follow what comptia say they control reality.

WPA2 uses AES

WEP is RC4 WPA is Tkip WPA2 is AES

Wi-Fi Protected Access 2 Pre-Shared Key or WPA2-PSK is a system of encryption used to authenticate users on wireless local area networks using a shared password as the key, a temporal key version of this is quite literally temporary. WPA2-PSK [AES] is the recommended secure method of making sure no one can listen to your wireless data while it is being transmitted back and forth between your router and other devices on your network. A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies, not a shared password. Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts the packets of data to provide secure encrypted communication between two computers over an Internet Protocol network used by virtual private networks through key exchanges.

D. I would go with the newer standard that is still compatible with TKIP. WPA2-PSK TKIP

From ChatGPT 4.0 C. WPA-PSK The technician should configure WPA-PSK (Wi-Fi Protected Access with Pre-Shared Key) to ensure compatibility with the control devices. This is because WPA-PSK uses TKIP (Temporal Key Integrity Protocol) as its encryption method and a symmetrical password (pre-shared key) for authentication, which meets the requirements of the industrial control system devices. Here's a brief overview of the other options: A. WPA2-Enterprise: This option uses stronger encryption (AES-CCMP) than required, and it employs a RADIUS server for authentication, which is not compatible with the specified requirements. B. WPA-Enterprise: This option uses TKIP for encryption but relies on a RADIUS server for authentication, making it incompatible with the control devices' requirements. D. WPA2-PSK: This option uses a stronger encryption method (AES-CCMP) than required, making it incompatible with the control devices' requirements.

D. WPA2-PSK. To ensure compatibility with the industrial control system's requirements of using TKIP encryption and a symmetrical password for connection, the technician should configure WPA2-PSK. WPA2-PSK (Wi-Fi Protected Access 2 with Pre-Shared Key) is a security protocol that uses a symmetrical password to authenticate wireless devices and encrypt data transmissions. It provides stronger encryption and better security than the older WPA-PSK protocol. TKIP (Temporal Key Integrity Protocol) is a legacy encryption protocol that is still supported by WPA2-PSK for backward compatibility with older devices.

D esta the good one since WPA2-PSK use TKIP encryption and requires symmetrical password option C use TKIP but dont require 802.1x

Answer: B This mode provides the security needed for wireless networks in business environments. It is more complicated to set up, and it offers individualized and centralized control over access to your Wi-Fi network. When users try to connect to the network, they need to present their login credentials. This mode supports 802.1x RADIUS authentication and is appropriate in the cases where a RADIUS server is deployed. WPA-Enterprise should only be used when a RADIUS server is connected for client authentication. Users never deal with the actual encryption keys. They are securely created and assigned per user session in the background after a user presents their login credentials. This prevents people from getting the network key from computers.

Sorry, I think it must be B! WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) uses a pre-shared key (PSK) to authenticate and encrypt wireless connections. It provides less security than WPA-Enterprise, as the PSK is the same for all devices and can be easily compromised if it is not properly secured. In the case of the industrial control system, the requirement for TKIP encryption and a symmetrical password suggests a higher level of security than is provided by WPA-PSK, making it the incorrect choice for this deployment.

i would go with C

WPA-Enterprise uses TKIP encryption and requires a symmetric password (or "Pre-Shared Key") to connect. This is the best option to ensure compatibility with the control devices that require TKIP and a symmetrical password. WPA2-Enterprise uses AES encryption which is not compatible with TKIP. WPA-PSK and WPA2-PSK are both designed for personal use and do not support the use of a symmetric password.

WPA-Enterprise: - symmetric password and TKIP

WPA uses TKIP; second, PSK are symmetrical.

WPA2-PSK requires a router with a passphrase, with a length between 8 to 63 characters, to encrypt the data in the network. It uses a technology named TKIP, i.e., Temporal Key Integrity Protocol, that requires network SSID and the passphrase to generate unique encryption keys for each wireless client. WPA2-PSK (AES) is more secure than WPA2-PSK (TKIP), but WPA2-PSK (TKIP) can be used with older devices that are not WPA2-PSK (AES) enabled devices.
