SPLK-1004 Search Tuning Performance And Dashboards Practice Test 2 — 15 Questions

Question 1

When a dashboard panel uses a base search and a post-process search, which command is NOT allowed in the post-process search?

Accepted Answer

metadata. Post-process searches are limited to transforming commands; they cannot perform operations that require raw event data or index retrieval, such as 'metadata' or 'tstats'.

Answer

eval

Answer

sort

Answer

stats

Question 2

You want to dynamically set the value of a token based on the result of a search. Which element should be used within the search block?

Accepted Answer

. The element allows you to execute token-setting logic once the search completes.

Answer

Answer

<set>

Answer

<final>

Question 3

A dashboard has multiple inputs. When a user changes one, you want the others to reset. How can you achieve this using Simple XML?

Accepted Answer

Define a 'change' block with for the other tokens.. You can use the or elements within an change block to manipulate tokens, effectively resetting other inputs.

Answer

Use an 'on_load' script.

Answer

Use a 'global' scope for all tokens.

Answer

Use the 'reset' attribute on the input.

Question 4

What is the benefit of using the 'tstats' command for dashboard panels?

Accepted Answer

It is significantly faster because it queries metadata files.. tstats operates on the tsidx files (metadata), which are extremely fast and perform much better than searching raw event data.

Answer

It automatically formats results for charts.

Answer

It retrieves the raw events for every search.

Answer

It allows joining multiple indexes automatically.

Question 5

Which attribute in an input element sets the label that the user sees?

Accepted Answer

label. The 'label' attribute defines the user-facing text for an input component.

Answer

text

Answer

name

Answer

display

Question 6

Which menu path in Splunk Web allows you to view the list of saved dashboards?

Accepted Answer

Settings > Dashboards. The 'Dashboards' menu item under the 'Apps' or 'Dashboards' navigation header provides access to the dashboard listing page.

Answer

Search > Reports

Answer

Activity > Jobs

Answer

Apps > Manage Apps

Question 7

You want to hide a panel based on the value of a token. Which attribute should you use in the dashboard XML?

Accepted Answer

depends="$token$". The 'depends' attribute controls visibility; if the token is present, the panel shows; if not, it remains hidden.

Answer

hidden="$token$"

Answer

visible="$token$"

Answer

show="true"

Question 8

Which of the following is an effective strategy to optimize a search that filters by a specific user?

Accepted Answer

Filter by indexed fields as early as possible.. Filtering by indexed fields (like index=, sourcetype=, or specific fields) first is the most critical step in search optimization.

Answer

Use the 'regex' command instead of 'where'.

Answer

Include a subsearch for all users.

Answer

Always put the 'stats' command at the start.

Question 9

When using the 'drilldown' tag, what is the purpose of the 'eval' element?

Accepted Answer

To compute or modify the value of a token during drilldown.. The 'eval' element allows you to perform calculations or string manipulations on the token value before it is passed to the destination.

Answer

To validate user permissions.

Answer

To execute a script.

Answer

To filter the target dashboard results.

Question 10

What is the best way to manage a search that is used in multiple panels of the same dashboard?

Accepted Answer

Create a base search with an ID and reference it in each panel.. Defining a base search with an ID and referencing it in panels avoids redundant queries, as the panels share the results of the base search.

Answer

Save each panel as a separate report.

Answer

Copy and paste the search string into each panel.

Answer

Use a macro for the search.

Question 11

Which TWO of the following are valid ways to improve search performance?

Accepted Answer

Filter by indexed fields as early as possible.. Using indexed fields (filtering) and limiting the time range are the two most effective ways to reduce search duration.

Answer

Use the join command for all data matching.

Answer

Always use wildcards at the beginning of terms.

Answer

Use the transaction command for all aggregations.

Question 12

Which TWO of the following are true regarding dashboard tokens?

Accepted Answer

Tokens are automatically scoped globally.. Tokens can be set manually via XML and are case-sensitive.

Answer

Tokens are case-insensitive.

Answer

Tokens require a restart to take effect.

Answer

Tokens can only be strings.

Question 13

Which THREE of the following are components of a drilldown interaction in a dashboard?

Accepted Answer

Condition. A drilldown consists of a trigger (the event), a destination (the link or target), and the token parameters being passed.

Answer

Field

Answer

Search

Question 14

Which TWO of the following are benefits of using a lookup instead of a join?

Accepted Answer

Reduced memory consumption.. Lookups are faster and consume less memory than joins.

Answer

Ability to handle real-time streaming data.

Answer

Support for subsearches.

Answer

Automatic index updating.

Question 15

Which THREE of the following are valid ways to optimize subsearches?

Accepted Answer

Reduce the total time range of the subsearch.. Limiting result size, using fields, and minimizing the scope are best practices for subsearch optimization.

Answer

Increase the subsearch timeout.

Answer

Use the join command instead.
