Storage is the target
On an interface, data throughput is measure based on ____ and _____.
clocking and encoding
vPC stands for _____ _____ _____ and has ____ points of management
Virtual port channel, 2
What is vPC? List 3 advantages.
Virtual port channels allow Nexus switches to appear as a single Port Channel to a third device. The benefits of vPC include the elimination of STP blocked ports, a loop-free topology, and the use of all available bandwidth. Other benefits include high availability and fast convergence when a link fails.

What is the purpose of FEX?
Support top-of-rack, middle-of-row, and end-of-row design
Describe the benefits of FabricPath
Eliminates need for spanning tree. Spreads traffic across all available paths. Server-to-server communication occurs over the shortest available path.
What does OTV offer?
Overlay Transport Virtualization offers Ethernat LAN extension over any network.
Describe LISP
LISP associates a location ID with IP addresses without changing the actual IPs.
Name the 2 components of traffic management inside a data center
RISE and Intelligent Traffic Director (ITD)
Describe one benefit of Service Profiles
Allows movement from the B-Series to the C-Series
System Link technology is a large component of the ___-Series of servers. What does it allow us to achieve?
M-Series. Allows servers to have nothing but CPU and memory. Other components (NIC, storage, etc.) are located outside of the chassis.
