A large e-commerce company has a Splunk environment ingesting web server logs from multiple data centers. The security team needs to visualize failed login attempts over time, grouped by geographic region. They have a lookup file geo_region.csv that maps IP addresses to regions. The lookup is defined in transforms.conf with max_matches=0 (all matches) and is used as an automatic lookup in props.conf for the sourcetype 'web_access'. The search returns events with multiple region values per IP (because max_matches=0). The team wants a single region per event for accurate counting. They also need to reduce the number of events processed by filtering only login failures (status=401). Which approach should be taken?

A Splunk admin is tasked with creating a dashboard that shows the average response time per server over the last hour, updated every 60 seconds. The data comes from a sourcetype 'app_log' with fields: server, response_time. The admin wants to use a single search with a timechart and set the dashboard's time range picker to 'Last 60 minutes'. However, the chart shows only one data point (the average for the entire hour) instead of per-minute intervals. What is the most likely cause and solution?

You are a Splunk administrator at a large e-commerce company with over 5,000 employees and millions of customers. The development team has created a dashboard that displays sales data by region, using a lookup table to map customer IDs to region names. The lookup file, 'customer_region.csv', is stored on the search head. Recently, the lookup table was updated with new customer IDs, but the dashboard continues to show old region names for new customers. You have verified that the lookup file contains the new mappings and that the file is correctly formatted. The dashboard uses the 'lookup' command in its base search. You have also confirmed that the lookup definition in transforms.conf points to the correct file. The lookup file is approximately 100 MB and is updated weekly. The dashboard is accessed by multiple users across the organization. The issue only affects new customers added in the latest update. Old customers still show correct regions. You have checked the file size and timestamp, and the new file is present. The Splunk version is 8.2. The search head is not clustered. No errors are appearing in the splunkd.log related to lookups. The dashboard uses a simple XML with a timechart and a lookup. The search string is: index=sales sourcetype=transactions | lookup customer_region.csv customer_id OUTPUT region | timechart count by region. You have also tried restarting the search head, but the issue persists. What is the most likely cause?

You are a Splunk power user working for a healthcare organization. You have created a visualization that shows patient wait times by department over the last 30 days. The chart uses a timechart command with a 'stacked' option. Recently, the chart started showing negative values for some departments, which is impossible because wait times cannot be negative. You have verified that the raw data is correct and contains only positive wait times. The search is: index=healthcare sourcetype=patient_wait | timechart span=1d avg(wait_time) by department. The chart is displayed as a stacked area chart. The negative values appear only for a few departments sporadically. You suspect the issue is related to how null values are handled. What could be causing the negative values?

You are a Splunk consultant for a financial services firm. They have a large lookup table containing customer account numbers and risk scores. This lookup is used in a critical compliance search that runs every hour. The search is failing with a memory error 'The search coordinator stopped the search due to memory usage'. You have already tried increasing the memory limit for the search via limits.conf, but the error persists. The lookup file is a CSV file of 2GB, with approximately 20 million rows. The search is: index=compliance sourcetype=transactions | lookup risk_scores.csv account_id OUTPUT risk_score | stats avg(risk_score) by transaction_type. The search runs on a single search head with 16GB RAM. The lookup is defined as static. What is the most effective optimization to resolve the memory error?

A user has created a dashboard panel using a 'chart' command with 'datacount by host'. The chart shows counts per host, but the hosts appear in alphabetical order. The user wants to sort the chart by count descending, so that the host with the most events appears first. The search is: index=main sourcetype=access | chart count by host. The dashboard is built using Simple XML. Which approach should be used to achieve the desired sorting?

You are a Splunk power user at a manufacturing company. You have created a timechart that shows machine temperature readings over time. The data is indexed with timestamps every minute, but the timechart shows gaps where no data exists because some machines may not report at all times. You want to fill the gaps with 0 values to avoid misleading visualizations. The current search is: index=manufacturing sourcetype=temperature | timechart span=1h avg(temp) by machine. Which modification to the timechart command will fill the gaps with 0?

You are a Splunk administrator for a multi-site deployment with two data centers: primary and remote. Users on the remote site report that a lookup used in a dashboard returns no results for data from their site, but the same lookup works perfectly on the primary site. The lookup is defined with 'local=true' in the transforms.conf. The lookup file is stored on the primary search head. The remote site has its own search head that queries data from both sites. The dashboard search is: index=main | lookup site_mapping.csv site_id OUTPUT location | stats count by location. Users on the remote site see rows with location=null for their data. What is the most likely cause?

Which TWO of the following statements about lookup tables in Splunk are true?

The security operations center (SOC) team at a medium-sized enterprise uses Splunk to investigate potential threats. They maintain a CSV lookup file named 'threat_intel.csv' that contains a list of known malicious IP addresses along with a threat score. The lookup is configured in transforms.conf as: [threat_intel] filename = threat_intel.csv match_type = WILDCARD(ip) They frequently run the following search to enrich firewall events with threat scores: index=firewall sourcetype=firewall_logs | lookup threat_intel src_ip OUTPUT threat_score | where threat_score > 5 Recently, analysts noticed that some IP addresses known to be present in the lookup file are not being matched in search results. They have verified that the lookup file is correctly formatted and contains those IPs, and the transforms.conf has not been altered. They also confirmed that the events contain the field src_ip with the correct IP addresses. Which of the following is the most likely cause of the missing matches?

A large e-commerce company uses Splunk to monitor transactions. They have a CSV lookup file named 'customer_lookup.csv' containing 5 million rows of customer data (customer_id, name, address, tier). The lookup is used in a search that runs every hour to generate a report of sales by customer tier: index=transactions sourcetype=transaction_logs | lookup customer_lookup customer_id OUTPUT name, address, tier | timechart count by tier The search often times out or takes too long to complete, impacting operational dashboards. The team is considering optimization strategies. The lookup file is updated daily and stored in a custom app directory. The Splunk environment is distributed with a single search head and multiple indexers. Which of the following recommendations would most effectively improve the search performance?

A Splunk administrator is creating a dashboard to visualize real-time network traffic data. The dashboard must include a lookup to enrich source IPs with location data.

Refer to the exhibit. The lookup 'lookup_user_info' is used in a search: `| lookup lookup_user_info user_id OUTPUT department`. Users report that many events show 'UNKNOWN' as department even though the user_id exists in the CSV. What is the most likely cause?

A company's security team uses Splunk to monitor firewall logs. They have a lookup file named 'threat_intel.csv' containing 10,000 IP addresses classified by threat level. The lookup is used in a dashboard that shows the number of blocked connections from high-threat IPs over the past 24 hours. Recently, the dashboard has become slow, taking over 30 seconds to load. The lookup file is updated every 15 minutes via a script that replaces the entire file. The search currently uses: `index=firewall | lookup threat_intel.csv src_ip OUTPUT threat_level | where threat_level="high" | stats count`. Which of the following is the MOST efficient way to improve dashboard performance?
