200-901 Practice Question: An engineer needs to transfer a router…
An engineer needs to transfer a router configuration file to a server in the same network using a simple protocol that does not require authentication. Which protocol is best?
⚠ Common exam trap
Cisco often tests the distinction between TFTP and SCP, where candidates mistakenly choose SCP because it is secure, overlooking the explicit requirement for a protocol that does not require authentication.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
TFTP
TFTP (Trivial File Transfer Protocol) is the best choice because it is a lightweight, connectionless protocol that operates over UDP (port 69) and does not require any authentication or user credentials. It is commonly used for transferring router configuration files and IOS images in local network environments where simplicity and speed are prioritized over security.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SCP
Why it's wrong here
SCP uses SSH for authentication and encryption, requiring credentials.
- ✓
TFTP
Why this is correct
TFTP has no authentication and is simple to implement.
- ✗
FTP
Why it's wrong here
FTP is incorrect because it requires authentication, typically a username and password, even for anonymous access where a generic credential (like 'anonymous' as username) is provided. The question explicitly specifies a protocol that does not require authentication. FTP is a robust client-server protocol for transferring files and would be the correct choice if the scenario required authenticated file transfers or did not stipulate the absence of authentication.
- ✗
HTTP
Why it's wrong here
HTTP typically requires a web server and may involve authentication; it's not as simple as TFTP for file transfers.
