正確答案:
Explanation:
* A firewall can direct all web traffic to a specific IP address.
* True: Firewalls can be configured to perform Network Address Translation (NAT) and port forwarding, which can direct all web traffic (typically on port 80 and 443) to a specific internal IP address.
* A firewall can block traffic to specific ports on internal computers.
* True: Firewalls can be configured with access control lists (ACLs) or rules to block traffic to specific ports on internal computers, enhancing security by restricting unwanted or harmful traffic.
* A firewall can prevent specific apps from running on a computer.
* False: Firewalls typically control traffic flow and do not prevent specific applications from running on a computer. Application control is usually managed by endpoint security software or application control systems.
* Directing Web Traffic: Firewalls can manage traffic redirection using NAT and port forwarding rules to route web traffic to designated servers or devices within the network.
* Blocking Specific Ports: Firewalls can enforce security policies by blocking or allowing traffic based on port numbers, ensuring that only permitted traffic reaches internal systems.
* Application Control: While firewalls manage network traffic, preventing applications from running typically requires software specifically designed for endpoint protection and application management.

Explanation:
The correct matching of the MFA factors to their examples is as follows:
* Entering a one-time security code sent to your device after logging in: Possession
* Holding your phone to your face to be recognized: Inherence
* Specifying your user name and password to log on to a service: Knowledge Here's why each factor matches the example:
* Possession: This factor is something the user has, like a mobile device. A one-time security code sent to this device falls under this category.
* Inherence: This factor is something the user is, such as a biometric characteristic. Facial recognition using a phone is an example of this factor.
* Knowledge: This factor is something the user knows, like a password or PIN.
Multi-Factor Authentication (MFA) enhances security by requiring two or more of these factors to verify a user's identity before granting access.
* Entering a one-time security code sent to your device after logging in.
* Factor: Possession
* Explanation: This factor relates to something you have, such as a device that receives a security code.
* Holding your phone to your face to be recognized.
* Factor: Inference (typically referred to as Inherence or Biometric)
* Explanation: This factor relates to something you are, such as biometric authentication like facial recognition.
* Specifying your username and password to log on to a service.
* Factor: Knowledge
* Explanation: This factor relates to something you know, such as a username and password.
* Possession Factor: This involves something the user has in their possession. Receiving a one-time security code on a device (e.g., phone) is an example of this.
* Inference Factor (Inherence/Biometric): This involves something inherent to the user, such as biometric verification (e.g., facial recognition or fingerprint scanning).
* Knowledge Factor: This involves something the user knows, such as login credentials (username and password).

正確答案:
Explanation:
The correct matching of the security options to their characteristics is as follows:
* WPA2-Enterprise: Uses a RADIUS server for authentication
* WEP: Uses a minimum of 40 bits for encryption
* WPA2-Personal: Uses AES and a pre-shared key for authentication
Here's why each security option matches the characteristic:
* WPA2-Enterpriseuses a RADIUS server for authentication, which provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.
* WEP (Wired Equivalent Privacy)is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today's standards.
* WPA2-Personal(Wi-Fi Protected Access 2 - Personal) uses the Advanced Encryption Standard (AES) for encryption and a pre-shared key (PSK) for authentication, which is shared among users to access the network.
These security options are essential for protecting wireless networks from unauthorized access and ensuring data privacy.
