Objective 4.9
200-301Describe the capabilities and functions of TFTP/FTP in the network.
Objective 4.9 sits in IP Services, which carries 10% of the CCNA exam. The questions below are original, written from the official objective title above, and each explanation cites the Cisco page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A technician points a switch at a TFTP server to fetch an image, then tries to browse the server's directory and to log in with a service account. Both attempts fail. Why do both fail?
Correct.
Checked against datatracker.ietf.org, August 2026Concept
A protocol designed to be small enough to fit in boot firmware carries only the operations that job needs. Everything a full transfer service offers beyond reading and writing a named file is left out on purpose.
Why B
The protocol can read and write a named file and nothing else: it cannot list directories and has no user authentication at all. The file name has to be known in advance, and access is controlled by the server's own configuration.
Source
IETF RFC 1350, The TFTP Protocol (Revision 2), checked August 2026It cannot list directories, and currently has no provisions for user authentication.
Now you: objective 4.9 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
An image copy over a satellite link with 600 ms of round trip delay crawls, although the link has plenty of bandwidth and shows no loss. What explains the throughput?
Sample question 2 of 3
A capture of a completed transfer ends with a data packet carrying 168 bytes, with no closing exchange after it. How did the receiver know the file was complete?
Sample question 3 of 3
An engineer captures an FTP session and sees two separate flows between the same pair of hosts. Which traffic travels on the connection that stays open throughout?
That’s 3 of the full CCNA bank.
