Exam SK0-005 topic 1 question 116 discussion

A. Use an MFA out-of-band solution. The most secure method to access servers located in remote branch offices is to use an MFA (multi-factor authentication) out-of-band solution. MFA adds an extra layer of security beyond the traditional username and password by requiring an additional form of authentication, such as a fingerprint or a one-time code sent to a mobile device. An out-of-band solution means that the second factor is sent through a separate channel or device, further reducing the risk of compromise. Telnet connections are not secure because they transmit data in clear text, making it vulnerable to interception and unauthorized access. Password complexity policies and role-based access policies are important security measures, but they alone are not enough to provide sufficient security for remote access to servers.

I think answer is A

I think answer is A MFA for the entire network and also to access a remote server. Some examples of out-of-band authentication (when paired with a typical online login) include: Push notifications sent to a mobile device QR codes with encrypted transaction data Biometric readers for fingerprint scans or facial recognition Phone calls for voice authentication

MFA and out of band could be an answer but MFA isn't specific to just secure remote access .. it is for the entire network. Out of band would be authentication that is done outside of the original communication.  Telnet is not secure A password complexity policy has nothing to do with most secure access method RBAC provides a consistent authentication and authorization mechanism for users access. Role-based access control (RBAC) restricts network access based on a person's role within an organization and has become one of the main methods for advanced access control. The roles in RBAC refer to the levels of access that employees have to the network.
