4.3.7 Section Quiz Candidate: Anthony Patrizzi (apatrizzi324@gmail.com) Date: 2/2/2024, 9:57:20 PM • Time Spent: 02:41 Score: 90% Passing Score: 80% Question 1. Correct You have placed a File Transfer Protocol (FTP) server in your DMZ behind your firewall. The FTP server is to be used to distribute software updates and demonstration versions of your products. However, users report that they are unable to access the FTP server. What should you do to enable access? Open ports 20 and 21 for outbound connections. Install a VPN. Move the FTP outside of the firewall. Define user accounts for all external visitors. Explanation To allow FTP traffic into your DMZ, you must open the correct ports on the firewall. For FTP, the correct ports are 20 and 21 for outbound connections. Installing a VPN is not necessary to grant access to external users. Defining user accounts may be required in some situations, but this scenario requires anonymous access. Moving the FTP server outside the firewall is not a secure action.

Question 2. Correct FTPS uses which mechanism to provide security for authentication and data transfer? IPsec Multi-factor authentication Token devices SSL Explanation File Transfer Protocol Secure (FTPS) uses Secure Sockets Layer (SSL) to provide security for authentication and data transfer. FTPS is an FTP replacement that brings reasonable security to an otherwise unsecure file-transfer mechanism. FTP by itself is unsecure because FTP transmits logon credentials in cleartext and does not encrypt transmitted files.

To transfer files to your company's internal network from home, you use FTP. The administrator has recently implemented a firewall at the network perimeter and disabled as many ports as possible. Now, you can no longer make the FTP connection. You suspect the firewall is causing the issue. Which ports need to remain open so you can still transfer the files? (Select two.) 80 20 21 23 443 Explanation FTP uses port 21 for connection requests and port 20 for data transfers. Both ports need to remain open for you to transfer files to your company's internal network from home. Telnet uses port 23, SSL uses port 443, and HTTP uses port 80.
