Cisco 300-540 SPCNI cheat sheet
Cisco 300-540 SPCNI · Keep the key ideas within reach.
Provider-cloud virtualized architecture and orchestration
Separate infrastructure, individual function and service orchestration roles.
VMs, containers and cloud models imply different responsibilities.
YANG, NETCONF, RESTCONF, gRPC and gNMI have distinct roles.
An accepted orchestration action still needs actual completion and service verification.
Cloud interconnect, routing and data-center connectivity
Cross-connects, routed services and encryption serve different needs.
BGP establishment does not prove intended route acceptance and forwarding.
Overlays and data-center extensions require explicit underlay and failure scope.
Evaluate physical/logical diversity and representative normal/failure behavior.
Provider-cloud availability, recovery and convergence
Duplicate components may still share a failure dependency.
Detection, convergence and preserved application state are different.
Anycast follows route selection, not a universal geographic-distance rule.
Verify the complete intended service under the actual failure model.
Provider-cloud infrastructure and management security
Management, control and data trust boundaries differ.
AAA, TLS/mTLS, MACsec and IPsec have distinct scope.
uRPF, RTBH and FlowSpec need actual topology and trust assumptions.
Enabled controls do not guarantee capacity or complete protection.
NFVI service assurance, telemetry and optimization
NFVI health and workload/service health require separate evidence.
Telemetry, logs, flows and packet captures have different coverage.
Acceleration requires supported hardware and explicit trade-offs.
An anomaly needs diagnosis, authorized response and measured verification.
