Exam CAS-004 topic 1 question 296 discussion

How can anyone vote BF? The requirements are simple: 1. Protect user internet activity - can be achieved by VPN tunneling. 2. Ensure connection is encrypted - that's exactly what tunneling does. 3. KEEP USER ACTIVITY HIDDEN - we all use forward proxies for this very reason. Public VPN providers do exactly these two things - tunneling + proxying. Since when does MAC Randomization "keep user activity hidden?" - it only randomizes the device's MAC address and contributes to anonymity, but it doesn't "hide" the user activity. This is something encryption does!

BF seems best. Proxy can't encrypt your data so the tunneling (VPN) to encrypt your data and hide internet activity, and the MAC address randomization to further conceal your activity connecting to wireless access points.

B. Tunneling: Tunneling refers to the process of using a secure, encrypted connection (often via a VPN) to route all network traffic through a secure channel. This ensures that the data transmitted between the mobile device and the destination server is encrypted, protecting it from potential interception and eavesdropping. F. MAC address randomization is a technique used to improve privacy on mobile devices, particularly when connecting to Wi-Fi networks. By periodically changing the Media Access Control (MAC) address, a device can avoid being tracked by its unique identifier, preventing third parties from monitoring user activity based on static MAC addresses. NOT Proxy, While a proxy can provide some privacy benefits by routing traffic through an intermediary server, it doesn’t necessarily guarantee encryption or protect against all forms of tracking and eavesdropping. Tunneling (via VPN) is more commonly used for secure, encrypted connections.

B. MAC address randomization involves periodically changing the Media Access Control (MAC) address of the device to prevent tracking by network observers. By randomizing the MAC address, it becomes harder for third parties to track the device’s location and usage patterns based on a static MAC address. F. MAC address randomization involves periodically changing the Media Access Control (MAC) address of the device to prevent tracking by network observers. By randomizing the MAC address, it becomes harder for third parties to track the device’s location and usage patterns based on a static MAC address. Not A. PROXY because Proxy servers can help with privacy and anonymity by routing internet traffic through a different server, but they do not inherently encrypt connections unless used in conjunction with other technologies like HTTPS. While proxies can help obscure user activity, they are not as robust as VPNs in providing encryption and privacy.

A. Proxy Reason: A proxy server can help hide a user's IP address and route internet traffic through a different server, masking the user's identity and location. It adds a layer of privacy by preventing direct connections between the user's device and the internet services they access. B. Tunneling (specifically using a VPN) Reason: Tunneling, particularly using a Virtual Private Network (VPN), encrypts the user's internet traffic and routes it through a secure server. This ensures that the connection is encrypted, protecting data from interception by third parties. It also hides the user's activity from ISPs and other potential eavesdroppers.

MAC does not keep user activity hidden. Going with A and B

BF is the best choice, mac Address randomization end at layer two, it will only lead to identical mac address in the CAM table creating chaus to the switch

To protect user internet privacy, ensure encrypted connections, and hide user activity on a mobile device, you should consider implementing the following: B. Tunneling: This involves using a VPN (Virtual Private Network) to create a secure, encrypted tunnel for internet traffic, which helps protect user privacy and encrypts data in transit. F. MAC address randomization: This is a technique where a mobile device changes its MAC address regularly, making it harder for third parties to track or identify the device based on its MAC address. It enhances user privacy.

B. Tunneling: Tunneling involves creating a secure, encrypted connection (tunnel) between the mobile device and a trusted server or network. It helps protect data in transit from eavesdropping and ensures privacy. Virtual Private Networks (VPNs) are a common way to achieve tunneling for mobile devices. F. MAC address randomization: MAC address randomization is a technique used to prevent tracking of a device based on its physical MAC address. This helps enhance user privacy by making it more difficult for third parties to identify and track the device.

AB seems logically correct.

MAC is only important in LAN. should not be selected as a choice

The correct answers are A. Proxy and B. Tunneling.
