- A
Telnet
Why wrong: Telnet provides unencrypted remote terminal access; all data including passwords is sent in cleartext, which is insecure.
- B
SSH
SSH (Secure Shell) encrypts all management traffic, providing secure remote command-line access.
- C
SNMP
Why wrong: SNMP is used for network management and monitoring, not for remote terminal sessions.
- D
HTTP
Why wrong: HTTP is used to access web interfaces, but it is unencrypted; HTTPS would be encrypted, but terminal sessions typically use SSH or Telnet.

N10-009 Network Operations Practice Question
This N10-009 practice question tests your understanding of network operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator needs to remotely manage multiple routers and switches. The management traffic must be encrypted. Which protocol should be used for the remote terminal sessions?
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
✓
SSH
SSH (Secure Shell) encrypts all traffic, including authentication credentials and session data, making it the correct choice for securely managing routers and switches over a network. Telnet transmits everything in plaintext, while SNMP and HTTP lack the interactive encrypted terminal session required for remote CLI management.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Telnet
Why it's wrong here
Telnet provides unencrypted remote terminal access; all data including passwords is sent in cleartext, which is insecure.
When this WOULD be correct
In a scenario where the question specifies a legacy network with no security requirements or asks for a protocol that does not require encryption, Telnet would be correct for remote terminal access.
- ✓
SSH
Why this is correct
SSH (Secure Shell) encrypts all management traffic, providing secure remote command-line access.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
SNMP
Why it's wrong here
SNMP is used for network management and monitoring, not for remote terminal sessions.
When this WOULD be correct
A question asking for a protocol to collect performance metrics or monitor device status from multiple routers and switches, especially when encrypted communication is required (SNMPv3).
- ✗
HTTP
Why it's wrong here
HTTP is used to access web interfaces, but it is unencrypted; HTTPS would be encrypted, but terminal sessions typically use SSH or Telnet.
When this WOULD be correct
When the question asks for a protocol to access a web-based management interface on a network device without encryption requirements, HTTP would be correct.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The N10-009 exam frequently reuses these exact scenarios with slightly different constraints.
✓SSHCorrect answer▾
Why this is correct
SSH (Secure Shell) encrypts all management traffic, providing secure remote command-line access.
✗TelnetWrong answer — click to see why▾
Why this is wrong here
Telnet transmits data, including credentials, in plaintext, so it does not provide encryption for remote terminal sessions, which is required by the question.
★ When this WOULD be the correct answer
In a scenario where the question specifies a legacy network with no security requirements or asks for a protocol that does not require encryption, Telnet would be correct for remote terminal access.
Why candidates choose this
Candidates often confuse Telnet with SSH because both provide remote terminal access, and they may overlook the encryption requirement or assume Telnet can be secured with other measures.
✗SNMPWrong answer — click to see why▾
Why this is wrong here
SNMP is used for network monitoring and management of device configurations, not for establishing remote terminal sessions. It does not provide an interactive command-line interface for routers and switches.
★ When this WOULD be the correct answer
A question asking for a protocol to collect performance metrics or monitor device status from multiple routers and switches, especially when encrypted communication is required (SNMPv3).
Why candidates choose this
Candidates may confuse SNMP's role in network management with remote terminal access, or think that because SNMP can manage devices, it can also be used for interactive sessions.
✗HTTPWrong answer — click to see why▾
Why this is wrong here
HTTP is not encrypted and is used for web traffic, not for remote terminal sessions to manage routers and switches.
★ When this WOULD be the correct answer
When the question asks for a protocol to access a web-based management interface on a network device without encryption requirements, HTTP would be correct.
Why candidates choose this
Candidates may confuse HTTP with HTTPS or think that web-based management is equivalent to terminal sessions, overlooking the encryption requirement.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between Telnet and SSH by presenting a scenario that requires encryption, hoping candidates overlook that Telnet offers no security and default to it because of its simplicity or familiarity.
Detailed technical explanation
How to think about this question
SSH operates over TCP port 22 and uses public-key cryptography for host authentication and symmetric encryption (e.g., AES, ChaCha20) for session confidentiality. In a production network, SSH keys should be managed via a PKI or SSH key distribution system, and older versions (SSH-1) are deprecated due to vulnerabilities; always enforce SSH-2 (RFC 4253). A common real-world scenario is using SSH with local or AAA (TACACS+/RADIUS) authentication to enforce role-based access control on Cisco IOS devices.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the N10-009 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
