Before installing the controller on Linux manually, you must ensure:

Question

Options

• AYou have root or sudo access
• BThe system meets the controller's hardware and software requirements
• CThe network is configured for DHCP
• DHigh availability is configured in the network

• A
  94% (16)
• D
  6% (1)

Explanation

Installing any controller on Linux manually requires root or sudo access (A) because system-level operations - writing to system directories, managing services, and modifying configurations - require elevated privileges without which the installation will fail outright. Meeting hardware and software requirements (B) is equally essential; insufficient RAM, disk space, or an unsupported OS version will cause the installation to fail or the controller to malfunction.

C is wrong because DHCP is not a prerequisite - many production systems use static IPs, and the controller can be installed regardless of how IP addressing is handled. D is wrong because high availability is an optional post-installation configuration for redundancy, not a prerequisite for the initial install.

Memory tip: Think of "before you install" as two gates you must pass - can you write to the system? (root/sudo) and will the system support it? (requirements). Everything else (DHCP, HA) is network design that happens before or after, not a hard install dependency.
