Which three types of interface are on the Multi-Rate 10G/40G Aggregation Line Card? (Choose three.)

The correct answer is B. SFP+ C. QSFP E. CPAK. SFP+ (B), QSFP (C), and CPAK (E) are the three interface types found on the Multi-Rate 10G/40G Aggregation Line Card because they directly support the card's dual-speed design: SFP+ handles 10G connections, QSFP handles 40G connections, and CPAK is Cisco's proprietary…

Explanation

SFP+ (B), QSFP (C), and CPAK (E) are the three interface types found on the Multi-Rate 10G/40G Aggregation Line Card because they directly support the card's dual-speed design: SFP+ handles 10G connections, QSFP handles 40G connections, and CPAK is Cisco's proprietary high-density optics module that also supports multi-rate operation on this platform. The distractors are wrong for distinct reasons: XFP (A) is an older 10G standard that predates SFP+ and is not used on this card; GBIC (D) is a legacy 1G form factor, far below the 10G/40G speeds in scope; and CFP (F) is a 100G form factor used on higher-capacity line cards, not this aggregation card.

Memory tip: Think "Speed Counts - Cisco's Proprietary Adds Kapacity" - SFP+, QSFP, CPAK. Eliminate GBIC (too old/slow), XFP (replaced by SFP+), and CFP (too fast/wrong tier).
