While preparing to implement a Synergy solution, you notice the uplinks are all rated at 10Gb/s and consume four of the HPE Virtual Connect SE 40Gb F8 Module ports. They want to maximize free ports…

Question

Options

• AUse a QSFP+ transceiver and AOC in place of the SFP+ DAC cables.
• BUse a QSFP+ AOC, and remove the SFP+ DAC cables and QSFP+ to SFP+ adapters.
• CUse a QSFP+ DAC splitter cable, and remove the SFP+ DAC cables and QSFP+ to SFP+
• DUse a MPO to Quad LC splitter cable in place of the SFP+ DAC cables.

Explanation

Using a QSFP+ DAC splitter cable (breakout cable) consolidates four 10Gb/s uplinks onto a single 40Gb QSFP+ port, replacing the four individual SFP+ ports currently in use - this frees three ports for future growth while maintaining the same aggregate bandwidth. Option A is wrong because swapping to a QSFP+ AOC without a splitter still occupies one port per uplink at 40Gb, solving nothing. Option B has the same flaw - a QSFP+ AOC is a single-link cable, not a breakout, so port count doesn't improve. Option D (MPO to Quad LC) is a fiber splitter used with optical transceivers, not applicable to a DAC copper environment, and wouldn't consolidate the port usage correctly.

Memory tip: Think "one QSFP+ port = 40Gb = 4×10Gb" - a DAC splitter (breakout) cable is the only option that physically breaks one 40Gb port into four 10Gb connections, turning a 4-port problem into a 1-port solution.
