Overview of the 1T6-521 Application Performance Analysis and Troubleshooting Exam
Network Engineers and Senior Systems Administrators must master Network General’s Expert Sniffer platform to execute granular application performance analysis and root-cause troubleshooting. Candidates demonstrate proficiency in capturing multi-tier traffic, reconstructing TCP streams, and interpreting complex protocol decodes for HTTP, SQL, DNS, and SMB layers. The exam mandates expertise in baseline development, latency visualization, and forensic packet inspection to isolate application-layer bottlenecks versus network-induced congestion. Practitioners apply advanced filtering, expert system alerts, and statistical flow analysis to optimize throughput within enterprise architectures. Technical competency centers on diagnosing distributed application latency, identifying retransmissions, and ensuring end-to-end service delivery across heterogeneous switched network environments.
