This 200-901 practice question tests your understanding of application deployment and security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A DevOps team is using Cisco AppDynamics to monitor a microservices application. They notice that a specific service's response time spikes under load. Which AppDynamics feature should be used to drill down into the transaction trace?
Health Rules
Why wrong: Health Rules define alerting conditions, not tracing.
Transaction Snapshots
Why wrong: Transaction Snapshots capture individual request traces, ideal for deep analysis.
Business Transactions
Business Transactions are high-level groupings, not individual traces.
Service Endpoints
Why wrong: Service Endpoints show entry points but not detailed traces.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Business Transactions
Business Transactions in AppDynamics represent the logical business operations (e.g., checkout, login) that span across multiple tiers. When a response time spike occurs, selecting the specific Business Transaction allows you to drill into its Transaction Snapshots, which capture the full distributed trace including call chains, method timings, and database queries. This is the correct entry point for root-cause analysis of performance degradation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Health Rules
Why it's wrong here
Health Rules define alerting conditions, not tracing.
Transaction Snapshots
Why it's wrong here
Transaction Snapshots capture individual request traces, ideal for deep analysis.
Business Transactions
Why this is correct
Business Transactions are high-level groupings, not individual traces.

Service Endpoints
Why it's wrong here
Service Endpoints show entry points but not detailed traces.
Common exam traps
Cisco often tests the distinction between the logical grouping (Business Transactions) and the raw trace data (Transaction Snapshots), trapping candidates who confuse the container with the content.

Command / output trap
Service Endpoints show entry points but not detailed traces.
Detailed technical explanation
Under the hood, AppDynamics instruments Java bytecode or .NET IL to capture every call within a Business Transaction, correlating them via correlation IDs (e.g., HTTP headers like 'X-Request-ID' or 'APPD_CORRELATION_HEADER'). Transaction Snapshots are sampled based on a configurable threshold (e.g., every 10 seconds or when response time exceeds 100ms) and store the full call graph, including exit calls to databases, queues, and external services. In a real-world scenario, a spike in the 'Checkout' Business Transaction might reveal a slow SQL query on the 'Orders' database, visible only by examining the snapshot's exit call details.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
