Understanding FTP and DNS Concepts

What does FTP stand for?

• File Transmission Protocol

• File Transfer Process

• File Transfer Protocol

• Fast Transfer Protocol

What is the primary purpose of the FTP protocol?

• To transfer files between a client and a server.

• To encrypt data during transmission.

• To manage network connections between devices.

• To display web pages on a browser.

Describe the difference between active and passive FTP modes.

• Both Active and Passive FTP use the same port for data transfer.

• Active FTP is faster than Passive FTP due to less overhead.

• Active FTP uses client-side port for data transfer, while Passive FTP uses server-side port.

• Active FTP uses server-side port for data transfer, while Passive FTP uses client-side port.

What is the role of a DNS server in the resolution process?

• To provide web hosting services for websites.

• To store user data for websites.

• To manage email delivery for domains.

• The role of a DNS server is to resolve domain names into IP addresses.

Explain the steps involved in the DNS resolution process.

• DNS resolution translates an IP address into a domain name.

• The DNS resolution process is completed instantly without any queries.

• The DNS resolution process only involves a single DNS server.

• The DNS resolution process involves querying multiple DNS servers to translate a domain name into an IP address.

What is an A record in DNS?

• An A record maps a domain name to a URL.

• An A record is used for email routing in DNS.

• An A record connects a domain name to a MAC address.

• An A record maps a domain name to an IPv4 address in DNS.

What is a CNAME record in DNS?

• A CNAME record is a DNS record that maps one domain name to another, allowing for domain aliasing.

• A CNAME record is used to store IP addresses for a domain.

• A CNAME record is a security feature that encrypts domain traffic.

• A CNAME record is a type of email forwarding service.

How does DNS caching improve performance?

• DNS caching improves performance by reducing lookup times and decreasing network traffic.

• DNS caching eliminates the need for any network connections.

• DNS caching only benefits local network devices.

• DNS caching increases server load and response times.

What is the TTL (Time to Live) in DNS records?

• TTL is the maximum number of DNS records allowed.

• TTL is the size of the DNS record in bytes.

• TTL is the frequency at which DNS records are updated.

• TTL is the duration in seconds for which a DNS record is cached.

What security measures can be implemented for FTP?

• Use plain FTP without encryption

• Use FTPS or SFTP, strong authentication, firewall restrictions, and regular software updates.

• Disable firewalls completely

• Implement weak passwords
