Q1.If you're browsing a website, what's a quick way to know that it's secure?

1. The website has a banner that says it's secure
2. The URL begins with https
3. The URL begins with tls
4. The URL begins with http

Websites that use https instead of http are more secure, since they encrypt data that's being sent between you and the website.

Q2.You're the sole IT employee at your company. Most of the computers in your fleet are Windows machines. Your boss wants you to set up a network file storage. What file service should you use?

1. Samba server
2. NFS server
3. HTTP server
4. Database server

While NFS servers can be used for shared network storage, they have interoperability issues with Windows. So, a better Windows alternative, like Samba, is your best bet.

Q3.Which of these is NOT an email protocol?

1. IRC
2. SMTP
3. POP3
4. IMAP

IRC, which stands for Internet Chat Relay, is an instant messaging chat system, not an email protocol.

Q4.Which file system protocols are intended for network use? Check all that apply.

1. SMB
2. Samba

4. NFS

SMB, which stands for Server Message Block, is a networking file system with good Windows interoperability.

4. Using a cloud service provider to manage your printers through a web browser

1. On a web server
2. On a database
3. On the local machine only
4. On a file transfer protocol (FTP) server

Customer information, like news articles, videos, large amounts of text, images, or audio files, generally gets stored in a database.

Q7.What is the main function of a database system?

1. A database is a physical server that stores web files and the HTTP server software.
2. Databases allow us to store, query, filter, and manage large amounts of data.
3. Databases store and retrieve files over a network.
4. Databases are a way of securing communication between a web server and client.

Customer information, like news articles, videos, large amounts of text, images, or audio files, generally get stored in a database. This is the most secure and efficient way to manage large amounts of data.
