Q: What is a UCS Fabric Interconnect?
A: The central management and networking component of Cisco UCS. Connects to all blades/servers and provides LAN/SAN connectivity.
Q: What is vPC on Nexus?
A: Virtual Port Channel — allows two Nexus switches to form a logical port channel to a downstream device, eliminating STP.
Q: What is the difference between UCS B-Series and C-Series?
A: B-Series: blade servers (installed in UCS chassis). C-Series: rack-mount servers (standalone or UCS-managed).
Q: What is Fibre Channel zoning?
A: Access control in SAN — defines which initiators (servers) can communicate with which targets (storage LUNs).
Q: What is NX-OS?
A: Cisco network operating system for Nexus switches. Based on Linux, supports VDCs, and has modular architecture.
Q: What is FCoE?
A: Fibre Channel over Ethernet — converges SAN (FC) and LAN (Ethernet) traffic on the same physical network.
Q: What does "show faults" display in UCS Manager?
A: Active faults/alarms with severity (critical, major, minor, warning, info) and affected component.
Q: What is a VSAN?
A: Virtual SAN — logical segmentation of a physical SAN fabric, similar to VLANs for Fibre Channel.
Q: What is an MDS switch?
A: Cisco Multilayer Director Switch — purpose-built SAN switch for Fibre Channel storage networking.
Q: What is DCB/lossless Ethernet?
A: Data Center Bridging — set of IEEE standards (PFC, ETS, DCBX) that make Ethernet lossless for FCoE and storage traffic.
Cisco Flashcard Study Strategy
Cisco exams heavily test protocol operations and configuration details. Use these flashcards to drill port numbers, protocol behaviours, and administrative distances. Pair flashcard sessions with Packet Tracer labs — when you encounter a card about OSPF neighbour states, open a lab and verify each state transition on a live topology. This combination of memorisation and practice builds the deep understanding Cisco exams demand.
