HP0-J73 · Question #149
What is one of the key advantages of converged network adapter (CNA)?
The correct answer is C. Multiple traffic types share the same link. A converged network adapter (CNA) consolidates Ethernet and Fibre Channel functionality into a single card, allowing multiple traffic types such as FCoE and LAN traffic to share the same physical link.

Why each option
A converged network adapter (CNA) consolidates Ethernet and Fibre Channel functionality into a single card, allowing multiple traffic types such as FCoE and LAN traffic to share the same physical link.
CNAs do not inherently provide greater available bandwidth compared to using separate dedicated adapters; the shared link must still be partitioned between traffic types.
A CNA does not guarantee a faster data transfer rate than dedicated HBAs or NICs operating at the same link speed.
A CNA integrates both a network interface card (NIC) and a Fibre Channel host bus adapter (HBA) into one device, enabling Fibre Channel over Ethernet (FCoE) and standard Ethernet traffic to share the same physical connection. This consolidation reduces the number of cables, adapters, and switch ports required in a storage network.
CNAs do not introduce a standardized connector for all components; they typically use standard SFP+ or Ethernet connectors that are not universal across all storage and network devices.
