Final exam Flashcards
iSCSI uses which type of storage?
Block level
In SCSI, ____ acts as the initiator and ____ acts as the target
Server is the initiator
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.
Which technology is associated with the description “split-brain”?
Virtual Port Channels (vPC)
This is a cloud appliance that houses the Virtual Supervisor Module (VSM) and the Network Analysis Module (NAM)
Nexus 1100
B-Series chassis connects to the ____ InterConnect, which in turn can connect up to the Nexus ___k.
Fabric Interconnect, 2k,
Febric extension refers to a FEX device (e.g. Nexus 2k) being (inside/outside) of a parents and acting as if it’s (internal/external) to a 7k.
Outside, internal
Inside a B-Series server, _____ uniquely tag each VM to identify traffic as it moves upstream. The tagging itself it referred to as _____.
Virtual interface cards (VICs), VN-TAG
A CNA stands for ____ _____ ____. The CNA can understand ___ traffic as well as ___ traffic.
Converged network adapter. LAN, SAN.
FCoE requires ___ Gbps systems.
10 Gbps.
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.
What does the UCS Common Platform Architecture allow us to do?
Allows UCS Manager to manage the B-Series, C-Series, M-Series
Orchestration =
Director

- Network Policies
- Relationships between the above 2
Describe Cisco’s Virtual Topology System (VTS)
Uses OpenFlow.
Does not do policy.
Programmable fabric!
