101 · Question #250

Which three methods can be used for initial access to a BIG-IP system. (Choose three.)

The correct answer is A. CLI access to the serial console port B. SSH access to the management port F. HTTPS access to the management port. Initial access to a BIG-IP system is established via the serial console CLI, SSH to the management port, or HTTPS to the management port - all out-of-band or secure in-band management methods.

Why each option

Initial access to a BIG-IP system is established via the serial console CLI, SSH to the management port, or HTTPS to the management port - all out-of-band or secure in-band management methods.

ACLI access to the serial console portCorrect

The serial console port provides direct CLI access independent of network configuration, which is essential for initial setup before any IP addressing is configured.

BSSH access to the management portCorrect

SSH to the management port provides secure encrypted CLI access once the management IP is assigned, and is a supported initial access method.

CSSH access to any of the switch ports

Switch (TMM data plane) ports are not used for management or initial access - management traffic must go through the dedicated management port or console.

DHTTP access to the management port

Plain HTTP access is not a supported initial access method because F5 enforces HTTPS for web UI access to protect credentials in transit.

EHTTP access to any of the switch ports

HTTP to switch ports is doubly incorrect - switch ports are not for management, and HTTP is not a valid access method.

FHTTPS access to the management portCorrect

HTTPS access to the management port provides secure access to the BIG-IP Configuration utility (web UI), which is a primary method for initial system configuration.

GHTTPS access to any of the switch ports

HTTPS to switch (data plane) ports is not valid for initial management access; those ports handle production traffic, not system administration.
