Use targeted practice questions to gauge your readiness and identify areas for further study before the exam.
Cheat Sheet
- First Hop Redundancy Protocols (HSRP/VRRP/GLBP) -
Understand how HSRP, VRRP, and GLBP ensure default”gateway availability by electing active and standby routers, with HSRP's 3 s hello and 10 s hold timers (Cisco Systems). Use the mnemonic "Hot Standby" for HSRP and remember VRRP's 1 s default hello for faster failover (IETF RFC 5798).
- Spanning Tree Enhancements (RSTP/PVST+) -
Review Rapid STP's sub-6 s convergence and how PVST+ runs a separate instance per VLAN to prevent loops (IEEE 802.1w/802.1D). A handy trick is "Every Bridge Blocks Before Forwarding" to recall STP port roles during topology changes.
- Link Aggregation with EtherChannel -
Study how EtherChannel bundles multiple physical links into one logical channel for redundancy and load-balancing, using XOR or LACP hashing algorithms (IEEE 802.3ad). Test configurations with "channel-group [ID] mode active" to enable LACP on Cisco switches.
- Quality of Service for Critical Apps -
Master DiffServ DSCP markings (e.g., EF = 101110 for voice) to prioritize latency-sensitive traffic (ITU-T Recommendation G.1010).Recall the "4 R's of QoS" (Rate, Remark, Reprioritize, Restrain) to design policies that guarantee bandwidth for VoIP and video.
- Network Virtualization & Overlay Technologies -
Explore VRF Lite for multi-tenant isolation and VXLAN overlays with 24-bit segment IDs to scale VLANs beyond 4 K (IETF RFC 7348). Remember "Virtualize to Economize" when mapping overlays to physical underlays in data centers.
