SCP-500 Quality Control & Assurance 4 — Questions and Answers
Question 1: In SolarWinds Orion, what is the purpose of the 'Unmanage' feature from a QA and change management perspective?
- Permanently removes a node from monitoring
- Suppresses alerts and polling for a node during planned maintenance without deleting it (Correct answer)
- Archives historical data for the node
- Resets all thresholds to defaults
Correct answer: Suppresses alerts and polling for a node during planned maintenance without deleting it
Unmanaging a node suspends polling and alert generation during maintenance windows, preventing false alerts without losing monitoring configuration.
Question 2: During a SolarWinds QA audit, you find that two different polling engines report conflicting availability percentages for the same node. What is the most likely root cause?
- Node is assigned to multiple polling engines simultaneously (Correct answer)
- The node has two different IP addresses being polled
- Database replication lag between polling engines
- Alert thresholds differ between engines
Correct answer: Node is assigned to multiple polling engines simultaneously
A node assigned to multiple polling engines can generate conflicting status data; each node should have a single responsible polling engine.
Question 3: A SolarWinds administrator is performing QA on custom SNMP pollers. Which step verifies that a custom poller is successfully retrieving data before assigning it to production nodes?
- Testing the OID in SNMP MIB Walker against a sample device (Correct answer)
- Deploying the poller to all nodes and checking for data after 24 hours
- Setting the poller interval to 60 seconds and waiting
- Enabling verbose logging globally
Correct answer: Testing the OID in SNMP MIB Walker against a sample device
Using the SNMP MIB Walker to test the OID against a sample device confirms the poller will return valid data before broad deployment.
Question 4: Which SolarWinds feature allows QA teams to define a hierarchy where alerts on child nodes are suppressed if their parent (upstream) device is already down?
- Alert dependencies (Correct answer)
- Network topology mapping
- Custom properties
- Alert escalation chains
Correct answer: Alert dependencies
Alert dependencies prevent child-node alerts from firing when a parent node is down, reducing alert storm noise during upstream failures.
Question 5: In a SolarWinds SAM QA review, an application monitor shows 'Unknown' status persistently. What is the first diagnostic step?
- Check the credential used by the component monitor for authentication failures (Correct answer)
- Reboot the monitored application server
- Delete and recreate the application template
- Increase the polling interval
Correct answer: Check the credential used by the component monitor for authentication failures
An 'Unknown' status in SAM typically means the monitor cannot authenticate or connect; verifying credentials is the first diagnostic step.
Question 6: A QA engineer is validating SolarWinds NTA (NetFlow Traffic Analyzer) data accuracy. Which comparison confirms that NTA flow data is consistent with interface bandwidth utilization in NPM?
- Comparing NTA top-talker bandwidth with NPM interface utilization graphs for the same time window (Correct answer)
- Verifying that SNMP trap counts match flow record counts
- Checking that node availability equals 100% in both modules
- Comparing alert counts between NTA and NPM
Correct answer: Comparing NTA top-talker bandwidth with NPM interface utilization graphs for the same time window
Correlating NTA top-talker data with NPM interface utilization graphs for the same period validates that flow data and SNMP bandwidth metrics are consistent.
Question 7: Which SolarWinds Orion database maintenance task is critical for long-term data quality and should be validated as part of a QA health check?
- Running Orion database maintenance jobs to prune old statistics and rebuild indexes (Correct answer)
- Manually deleting nodes older than 90 days
- Exporting all alerts to CSV weekly
- Disabling historical data retention
Correct answer: Running Orion database maintenance jobs to prune old statistics and rebuild indexes
Orion's built-in database maintenance jobs prune aged statistics, rebuild indexes, and keep the database performant, directly affecting data quality and query accuracy.
