Which card has the resources to run multiple services?

Question

Options

• Aredundant crossbar card
• Bswitch processor I/O card
• Csystem management card
• Dpacket service card

• A
  4% (1)
• C
  7% (2)
• D
  89% (25)

Explanation

D is correct because the Packet Service Card (PSC) is purpose-built with dedicated processing resources (CPU, memory) specifically to host and run multiple concurrent network services - such as deep packet inspection, NAT, QoS, and firewall functions - all on a single card.

A (Redundant Crossbar Card) is wrong because its role is to provide high-speed switching fabric connectivity and redundancy across the backplane, not to execute services.

B (Switch Processor I/O Card) is wrong because it handles input/output operations for the switch processor itself - it's a connectivity and control component, not a multi-service execution platform.

C (System Management Card) is wrong because it manages system-level functions like monitoring, configuration, and control plane operations - administrative duties, not running data-plane services.

Memory tip: Think of the word "service" in the name - only the Packet Service Card literally has "service" in its title, signaling it's the one designed to run services.
