here's one of the questions from a practice exam i took:

===
A system administrator moves a file from a server to a client using Secure Shell (SSH) over port 22. Compare the protocols for file transfers to deduce the protocol utilized.
- TFTP
- FTPES
- SFTP (your answer, correct)
- FTPS
===

here's "what you need to know", the text it brings up when you're reviewing a question:

===
Domain Name System Security Extensions (DNSSEC) helps to mitigate against spoofing and poisoning attacks by providing a validation process for DNS responses. The authoritative server for the zone creates a package of resource records, called an RRset, signed with a private key known as the zone signing key.

DNS server cache poisoning is a redirection attack that aims to corrupt the records held by the DNS server itself.

DNS spoofing is an attack that compromises the name resolution process. The attacker may compromose the process of DNS resolution by replacing the valid IP address for a trusted website.

Dynamic Host Configuration Protocol (DHCP) provides an automatic method for network address allocation. It can include optional parameters such as the default gateway, DNS address, or the DNS suffix.
