Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 213

A network engineer must configure a Fibre Channel interface on the Cisco MDS 9000 Series Switch. The configuration must meet these requirements:
• The interface must be disabled when the bit errors threshold is exceeded.
• Buffer-to-buffer credits must be set to the maximum value.
• The interface must have full bandwidth allocated for its port group.

Which command set configures a Fibre Channel interface that meets these requirements?

Answer options

• A. interface fc1/1 switchport bit-errors switchport fcrxbbcredit 220 mode Fx switchport rate-mode dedicated
• B. interface fc1/1 switchport ignore bit-errors switchport fcrxbbcredit 255 mode Fx no switchport rate-mode
• C. interface fc1/1 no switchport ignore bit-errors switchport fcrxbbcredit 255 mode Fx switchport rate-mode dedicated
• D. interface fc1/1 no switchport bit-errors switchport fcrxbbcredit 220 mode Fx no switchport rate-mode

Correct answer: C

Explanation

The correct answer is C because it disables the interface when bit errors occur, sets the maximum buffer-to-buffer credits to 255, and allocates the full bandwidth for the port group with the dedicated rate mode. Option A incorrectly enables bit-errors, while B ignores bit-errors and does not allocate bandwidth properly. Option D also enables bit-errors and sets buffer credits incorrectly.
