Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
SSH
This is correct because SSH supports encrypted remote administration.
Telnet
Why wrong: This is wrong because Telnet sends traffic in clear text.
Open wireless access
Why wrong: This is wrong because WLAN openness is unrelated to secure device administration.
Native VLAN 1
Why wrong: This is wrong because native VLAN choice is unrelated to encrypted management access.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
SSH
The best choice is SSH because it provides encrypted remote administrative access. In plain language, the engineer wants administrators to keep managing devices remotely, but without exposing credentials or session contents in clear text. SSH solves that by protecting the traffic in transit, which is why it is preferred over older plaintext protocols such as Telnet. This is a core management-plane security principle. The goal is not to remove remote administration, but to perform it safely. The correct answer is the one that aligns with secure remote access rather than convenience at the expense of protection.
Key principle: SSH provides encrypted remote administrative access, protecting session data and credentials from interception during transit.

SSH
Why this is correct
This is correct because SSH supports encrypted remote administration.

Related concept
SSH provides encrypted remote administrative access, protecting session data and credentials from interception during transit.
Telnet
Why it's wrong here
This is wrong because Telnet sends traffic in clear text.
When this WOULD be correct
If the exam question asked for a method of remote access that prioritizes speed and simplicity over security, and the context was a controlled environment where security risks are minimal, Telnet could be considered acceptable.
Open wireless access
Why it's wrong here
This is wrong because WLAN openness is unrelated to secure device administration.
When this WOULD be correct
If the question were about providing remote access to a public network where encryption is not a concern, and the focus was solely on ease of access rather than security, then open wireless access could be considered a valid option.
Native VLAN 1
Why it's wrong here
This is wrong because native VLAN choice is unrelated to encrypted management access.
When this WOULD be correct
If the question asked about configuring a network switch for management access without any security requirements, or if it specifically focused on VLAN configurations for untagged traffic, then selecting Native VLAN 1 could be correct.
Option-by-option analysis
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
Why this is correct
This is correct because SSH supports encrypted remote administration.
Why this is wrong here
Telnet is incorrect because it transmits data, including passwords, in plaintext, making it insecure for remote administrative access where session content protection is required.
★ When this WOULD be the correct answer
If the exam question asked for a method of remote access that prioritizes speed and simplicity over security, and the context was a controlled environment where security risks are minimal, Telnet could be considered acceptable.
Why candidates choose this
Candidates may choose Telnet due to its historical use in networking and familiarity, mistakenly believing that it is still a viable option for remote access without recognizing the security implications.
Why this is wrong here
Open wireless access does not provide any encryption or security for data transmitted over the network, making it unsuitable for protecting session contents in transit during remote administrative access.
★ When this WOULD be the correct answer
If the question were about providing remote access to a public network where encryption is not a concern, and the focus was solely on ease of access rather than security, then open wireless access could be considered a valid option.
Why candidates choose this
Candidates may choose this option due to a misunderstanding of wireless security, believing that open access is sufficient for remote management without recognizing the risks of unencrypted data transmission.
Why this is wrong here
Native VLAN 1 is primarily used for untagged traffic on a switch and does not provide any encryption or secure access for remote administration. It is not suitable for protecting session contents in transit.
★ When this WOULD be the correct answer
If the question asked about configuring a network switch for management access without any security requirements, or if it specifically focused on VLAN configurations for untagged traffic, then selecting Native VLAN 1 could be correct.
Why candidates choose this
Candidates may be tempted by this option because they recognize VLANs as a fundamental networking concept and might mistakenly associate Native VLAN 1 with management access without considering the security implications.

Common exam traps
A common exam trap is selecting Telnet because it allows remote access, ignoring that it transmits data in clear text. This mistake overlooks the critical security requirement to protect session contents during transit. Another trap is choosing options unrelated to encryption, such as native VLAN or open wireless access, which do not address secure remote management. Candidates must focus on protocols that provide confidentiality and integrity for administrative sessions, not just connectivity.
Detailed technical explanation
Secure remote administration is essential for protecting network devices from unauthorized access and data interception. SSH (Secure Shell) is a protocol that encrypts all data exchanged between the administrator and the device, including credentials and command output. This encryption prevents attackers from capturing sensitive information during transmission, which is a fundamental security principle in network management. Cisco devices support SSH as the preferred method for secure remote access, replacing older protocols like Telnet. The decision to use SSH over Telnet is based on the need to protect management-plane traffic. Telnet sends all data in plaintext, making it vulnerable to sniffing and man-in-the-middle attacks. SSH uses cryptographic techniques to authenticate both ends of the connection and encrypt the session, ensuring confidentiality and integrity. In Cisco IOS, enabling SSH involves generating cryptographic keys and configuring user authentication, which aligns with security best practices tested in the CCNA exam. Exam candidates often confuse unrelated concepts such as VLAN configurations or wireless access settings with secure management. While native VLANs and wireless security are important in their contexts, they do not encrypt remote administrative sessions. The practical takeaway is that SSH is the only option among the given choices that directly addresses the requirement for encrypted remote access, making it the correct and secure choice for managing Cisco devices remotely.
Key takeaway
SSH provides encrypted remote administrative access, protecting session data and credentials from interception during transit.
Real-world example
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
