You are a Splunk administrator at a financial services company. The company has a distributed Splunk environment with 10 indexers and 2 search heads. You have created a data model named 'transaction_analytics' to analyze financial transactions. The data model is accelerated with a summary range of 7 days. Recently, users have reported that dashboards using this data model are extremely slow, sometimes timing out. You check the acceleration status and see that the summary is 'Building' but never completes. The splunkd.log on the search head shows repeated messages: 'Data model acceleration: query timed out after 300 seconds.' The base search for the data model is: index=transactions sourcetype=fin_events | eval risk_score=if(amount>10000, 'high', 'low') | fields transaction_id, user, amount, risk_score, _time. The data model has one root event with two child datasets: one for high-risk transactions and one for low-risk transactions. The total data volume is about 500 GB per day. The indexer where the summary is built has 16 GB of RAM and the search head has 32 GB. What is the best course of action to resolve the acceleration build timeout?

A security team wants to create a data model to analyze authentication events from multiple sources (Windows Event Log, Linux syslog, and VPN logs). The data model should normalize the fields for user, source IP, and action (success/failure). Which Splunk best practice should be applied when designing this data model?

A Splunk administrator notices that a data model acceleration summary is consuming excessive disk space on the indexers. The data model is used for a dashboard that refreshes every 30 minutes. What is the best course of action to reduce disk usage while maintaining dashboard performance?

Which TWO statements about designing Splunk data models are correct? (Choose two.)

Refer to the exhibit. A Splunk user is building a data model for Apache error logs. The configuration above extracts an error_type field. However, when previewing data in the data model, the error_type field is not available. What is the most likely cause?

A large e-commerce company uses Splunk to monitor its web application. They have a data model named 'Web_Transactions' that contains fields: status_code, response_time, uri, user_agent. The data model is accelerated with a 30-day time range. Recently, the operations team reported that the dashboard showing average response time by URI is loading slowly, taking over 30 seconds to display. Upon investigation, you find that the data model acceleration summary job is taking longer to complete and sometimes fails. The indexers have sufficient CPU and memory, but the disk I/O is high during the summary job. The volume of web logs is approximately 500 GB per day. Which action should the Splunk administrator take to improve dashboard performance?

Which TWO of the following are best practices when creating and using data models in Splunk?

Refer to the exhibit. A user runs the search shown. The search returns results, but the user wants to use a data model to make future searches faster and more consistent. Which data model should the user select and what is the correct acceleration setting?

You are a Splunk administrator for a large e-commerce company. The security team frequently runs searches against the web access logs (sourcetype=access_combined) to investigate suspicious activity. These searches often take 5-10 minutes to complete, and the team is frustrated. You decide to implement a data model to accelerate these searches. After creating a data model based on the CIM Web model and enabling acceleration for the 'Web' dataset, you notice that the acceleration summary size grows to over 50 GB and the rebuild process takes more than an hour every night, causing some searches to time out during the rebuild window. What is the most effective way to address this issue?

Which THREE of the following are components of a data model in Splunk?

You are a Splunk administrator for a large e-commerce company. The company ingests approximately 500 GB of web server logs per day into a single index named 'web_logs'. A data model named 'Web_Transactions' has been created to analyze user browsing behavior. The data model has a root event with no constraints, and three child objects: 'Page_Views', 'Searches', and 'Purchases'. Each child object has a constraint based on a key-value pair in the logs: e.g., 'action=view', 'action=search', 'action=purchase'. The data model is accelerated with a 7-day summary, but reports that query specific child objects are taking over 10 minutes to return. The reports use |tstats and filter on common fields like 'user_id' and 'session_id'. The admin suspects the acceleration summary is too large. Which of the following actions will most effectively reduce report latency while maintaining the ability to analyze all three transaction types?

You are working as a Splunk consultant for a financial services firm. They have multiple data sources: application logs, database audit logs, and network firewall logs. The security team needs to correlate events across these sources to detect potential fraud. You decide to create a data model named 'Security_Events'. The data model will be used with tstats for real-time dashboards. The logs vary in volume: application logs are 200 GB/day, audit logs are 50 GB/day, and firewall logs are 100 GB/day. The firm wants to optimize performance and storage. The data model currently has one root event with no constraints and three child objects with constraints based on sourcetype. The admin is concerned about acceleration storage costs. Which of the following is the best approach to balance performance and storage?

A small business uses Splunk to monitor their point-of-sale (POS) system. They have a data model named 'POS_Transactions' that is not accelerated. The owner wants to create a simple dashboard showing daily sales totals. They write a search using |tstats against the data model, but it returns 'No events found'. A plain search over the same index returns expected results. What should the owner do to resolve this?

You are an admin for a large healthcare organization that uses Splunk for compliance monitoring. You have a data model named 'Patient_Access' that tracks access to patient records. The data model includes fields like 'employee_id', 'patient_id', 'access_time', and 'action'. The data model is accelerated with a 30-day summary. Recently, a new compliance report requires filtering on a field named 'department', which is not currently part of the data model. You add 'department' as a new field to the root event of the data model. After this change, reports using the data model become slower. The data model's acceleration summary size has significantly increased. What is the most likely reason for the slowdown?

A media company uses Splunk to analyze user engagement across their website. They have a data model named 'User_Actions' with two child objects: 'Page_Views' and 'Clicks'. The data model is accelerated. The marketing team creates a report that uses |tstats to count the number of 'Page_Views' per user_id. The results seem low compared to an equivalent search using |search. Upon investigation, you find that the 'Page_Views' object has a constraint that filters events where 'event_type=page_view'. The base search returns many events with 'event_type=Page View' (note the space). What is the issue and the correct fix?

A large e-commerce company ingests 10 TB/day of web access logs into Splunk. They have enabled the CIM-compliant Web data model and created data model acceleration with a 90-day range. Users run reports using pivot to analyze HTTP status codes, client IPs, and URIs. Recently, two issues arose: (1) Pivot reports are returning incomplete or outdated results, sometimes missing data from the last few hours. (2) Acceleration summary size has ballooned to over 500 GB, causing search head performance degradation. The Splunk admin suspects that data model acceleration is not configured optimally. Upon inspection, the Web data model's root search contains a complex filter with multiple eval commands and lookups, and the acceleration time range is set to the same 90 days as the summary range. The admin also notices that the data model is defined as non-time-based, even though the events have timestamps and the pivot often uses time ranges. What is the best course of action to resolve both issues while maintaining accuracy and performance?

Which two of the following are best practices when designing Splunk data models? (Choose two.)

Refer to the exhibit. A Splunk admin runs a search using the 'Authentication' data model and notices that the search does not use the acceleration summaries. The admin confirms that acceleration is enabled and the summary range is set correctly. What is the most likely reason for the acceleration being ignored?

A financial services company uses Splunk to monitor authentication logs from 500 remote servers. They created a data model named 'Authentication' with 15 fields including 'user', 'src_ip', 'dest_ip', 'action', and 'status'. They enabled acceleration with a summary range of 1 day and set the maximum search time range to 30 days. After one month of operation, searches against the data model that used to complete in seconds now time out after 60 seconds. The average daily log volume is 10 GB. The admin runs | datamodel Audit and discovers that the summary size is approximately 5 GB per day, which is similar to the raw data index size. The search head has 16 GB RAM and 4 CPU cores, and no other resource issues are observed. What is the most likely cause of the performance degradation?
