Which THREE of the following are valid ways to troubleshoot a slow dashboard?

A dashboard panel runs a search that returns 10,000 events, but the panel only displays a single-value element showing the event count. Users report the dashboard is sluggish. Which Splunk search command should you add to the base search to reduce the data returned to the panel while preserving the count?

A dashboard panel's search reads 12 GB from disk but returns only 4,000 events. In Search Inspector, which metric should you investigate first to reduce unnecessary disk reads?

A dashboard uses a base search that returns 50,000 events, and three panels each apply a post-process search to summarize those events differently. Users report that the dashboard takes a long time to load and that the post-process searches sometimes fail with a 'post process search cannot be used' error. Which action best resolves the loading delay and the error?

A dashboard uses a base search with a post-process search for each of six panels. Users report that changing the time range picker does not update the panels. The base search includes earliest=-24h latest=now. What is the most likely cause?

A dashboard panel runs a search that aggregates firewall events by src_ip. Users report the panel takes over a minute to render. The search uses `stats count by src_ip` after a base search that retrieves 30 days of data. The Search Inspector shows the search is reading far more events than needed, and the aggregation is spilling to disk. Which change is most likely to reduce the panel's render time while preserving the result?

A dashboard has a base search that returns a summarized result set, and several panels use post-process searches. You notice that one panel's post-process search returns no results while the base search clearly has data. Which TWO configuration issues could cause a post-process search to return no results? (Choose two.)

A dashboard panel runs a search that aggregates web access logs over the last 30 days. Users report the dashboard takes over a minute to load, and the Search Inspector shows high disk read time. The search is not scheduled and there is no acceleration. Which action should you take to reduce the panel's load time while preserving the ability to view the most recent 30 days of data?

A dashboard panel shows a timechart of web request latency, and users want to click a point on the chart to open a new search in a separate window that lists the individual slow requests for that time. Which dashboard feature should you configure to enable this behavior?

A dashboard uses a base search in a `<search>` element and several panels that reference it with `<search base="...">`. Users report that changing a time token does not update all panels consistently, and some panels show stale data. You need to correct the dashboard so all panels re-run when the token changes. (Choose two.)

You are building a dashboard with a base search that returns a large result set, and three panels that each perform different statistical calculations on that same result set. You want to minimize the number of times the base search runs and ensure all panels update together. Which approach should you use?

A dashboard has a base search that runs against a large index and takes 30 seconds to complete. Several panels use post-process searches to summarize the base results. Users complain that the dashboard is slow to load and that changing an input causes the entire base search to re-run. Which approach best improves the dashboard's performance?

You are building a dashboard with a text input that sets a token named `filter_field`. You want the token to be available to all panels and to have a default value of `status`. Which XML element and attribute should you use to define this input?

A dashboard has a panel that shows a table of error counts by host. Users want to click a host name and open a new dashboard filtered to that host. Which Simple XML element defines this behavior on the table panel?

You have a dashboard with a base search that returns a large result set, and three panels that each apply different transforming commands to that base search. You want to avoid running the base search three times. Which approach should you use?

You are optimizing a dashboard that uses several panels with inline searches. You want to reduce the overall search load and improve performance. Which two actions should you take? (Choose two.)

You are creating a dashboard that uses a dropdown input to set a token, and you want the selected value to be used in a panel's search. Which two statements are true about how the token is referenced and used in the dashboard? (Choose two.)

A power user notices that a dashboard's panels each run nearly identical base searches, causing high search load. The user wants a single search to run once and have multiple panels reuse its results without re-running the search. Which approach should be used?

You are creating a dashboard that includes a table panel showing the top 10 source IP addresses by event count. You want users to be able to click on a source IP in the table and have a second panel update to show all events from that IP. Which dashboard feature should you configure to enable this behavior?

You are using the Search Job Inspector to diagnose a slow search. You notice that the 'execution costs' show a high value for 'bucket_count' and 'disk_usage'. Which action is most likely to reduce these costs?

A power user needs to identify which dashboard panels are consuming the most resources and slowing down the dashboard. Which Splunk feature should the user consult to view the search job details, including execution time and resource usage, for each panel's search?

You are troubleshooting a dashboard that uses a base search and several post-process searches. The base search is `index=app | stats count by user, action`. One post-process search is `| search action=login | top user`. Users report that the top user panel sometimes shows incorrect counts compared to a direct search `index=app action=login | top user`. What is the most likely cause of the discrepancy?

A dashboard uses a base search that returns 100,000 events. The dashboard has three panels, each with a post-process search that performs a `stats` calculation. Users report that the dashboard is slow to load. Which Splunk feature can you use to reduce the load time by reusing the base search results across panels?

A dashboard uses a base search with post-process searches. Users report that some panels show incorrect results after the base search completes. You need to troubleshoot the issue. Which two actions should you take to identify the cause? (Choose two.)

A power user is optimizing a dashboard that uses a base search with post-process searches. The base search returns events with many fields, but only a few fields are used by the post-process searches. Which action will most effectively reduce the amount of data transferred from the base search to the post-process searches?
