A network administrator needs to securely transfer backup configuration files from a router to a remote server over the internet. Which protocol should be used?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
TFTP
Incorrect. TFTP is unencrypted and lacks authentication, making it unsuitable for secure transfers over the internet.
B
Distractor review
FTP
Incorrect. FTP transmits credentials and data in plaintext, which is insecure over the internet.
C
Best answer
SCP
Correct. SCP uses SSH for encryption, providing secure file transfer.
D
Distractor review
SNMP
Incorrect. SNMP is used for monitoring and managing network devices, not for file transfers.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this N10-009 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: SCP — SCP (Secure Copy) provides encrypted file transfer using SSH, ensuring confidentiality and integrity. TFTP and FTP transmit data in plaintext, making them insecure for internet transfers. SNMP is used for network management, not file transfer. Therefore, SCP is the appropriate choice for secure backup transfers.
