Sample Practice Questions

Try these 10 sample questions from the IBM Security QRadar SIEM V7.5 Analysis practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

  1. 1While triaging an offense, an analyst needs the list of events that contributed to it. What should the analyst select in the Offense Summary?

    1. A.The event link in Event/Flow countCorrect answer: A
    2. B.The flow link in Event/Flow count
    3. C.The link in Source IP(s)
    4. D.The link in Destination IP(s)

    Explanation: IBM states: "To see the list of events and flows that contributed to the offense, click the Event or Flow links." The event link selects events; the flow and IP links provide different views.

    Reference: IBM QRadar 7.5 User Guide — Chapter 4, Investigating an offense by using the summary information, Event/Flow count, p. 36

  2. 2An analyst reviews a rule that checks a username string and searches the full event payload with a regular expression. Which observation is relevant when recommending how to reduce rule processing cost?

    1. A.The payload regex test is more expensive than the username string testCorrect answer: A
    2. B.The username string test is more expensive than the payload regex test
    3. C.The two tests always require identical processing effort
    4. D.The payload regex test is evaluated without inspecting the payload

    Explanation: IBM notes that "checking whether a username matches a string is a simple test that can be performed quickly, but running a regex test against the event payload is a lot more expensive." The analyst can consider this difference when recommending test ordering.

    Reference: QRadar: Considerations of Rule Performance — Complexity of tests

  3. 3An analyst compares event timestamps and needs the time recorded in the original log source event. Which field provides it?

    1. A.Start Time
    2. B.Storage Time
    3. C.Log Source TimeCorrect answer: C
    4. D.Offense Duration

    Explanation: IBM describes Log Source Time as "The time that is recorded in the raw event from the log source." Start Time is when QRadar receives the raw event and Storage Time is when it stores the normalized event.

    Reference: IBM QRadar 7.5 User Guide — Chapter 4, Investigating events, time fields, p. 39

  4. 4An analyst removes an item from a standard QRadar dashboard and later needs it again. What is the documented effect of removing it?

    1. A.The item can be added to a dashboard againCorrect answer: A
    2. B.The item cannot be added to any dashboard again
    3. C.The item can return only after restoring a backup
    4. D.The item can return only after recreating its search

    Explanation: IBM states: "You can remove items from a dashboard and add the item again at any time." Removing it does not remove the item completely.

    Reference: IBM QRadar 7.5 User Guide — Chapter 3, Removing dashboard items, p. 25

  5. 5An analyst wants to enter an AQL search string to select and group event fields in the QRadar interface. Which search option supports this?

    1. A.Advanced SearchCorrect answer: A
    2. B.Quick Filter
    3. C.Quick Searches
    4. D.Saved Search Groups

    Explanation: IBM directs users to "Use the Advanced Search field to enter an Ariel Query Language (AQL)" specifying fields and grouping. Quick Filter is for payload text, while saved-search navigation does not itself accept the AQL string.

    Reference: IBM QRadar 7.5 User Guide — Chapter 10, Advanced search options, p. 153

  6. 6In the Offense Summary, how does QRadar display the status of an active offense?

    1. A.It displays the active status icon
    2. B.It displays no status iconCorrect answer: B
    3. C.It displays the hidden status icon
    4. D.It displays the closed status icon

    Explanation: IBM states: "QRadar does not display a status icon when an offense is active." An active offense therefore has no status icon, rather than any of the named status icons.

    Reference: IBM QRadar 7.5 User Guide — Chapter 4, Investigating an offense by using the summary information, Status, p. 35

  7. 7An existing reference set has the wrong data type. What does QRadar allow an analyst to change when editing that set?

    1. A.The data values, but not the data typeCorrect answer: A
    2. B.The data type, but not the data values
    3. C.Both the data type and the data values
    4. D.Neither the data type nor the data values

    Explanation: IBM states: "When you edit a reference set, you can change the data values, but you can't change the type of data that the reference set contains." A different type therefore requires a different set.

    Reference: IBM Security QRadar Administration Guide — Chapter 7, Adding, editing, and deleting reference sets, p. 201

  8. 8A flow travels from a remote network to a local network. Which QRadar direction label describes it?

    1. A.R2LCorrect answer: A
    2. B.L2R
    3. C.L2L
    4. D.R2R

    Explanation: IBM defines Remote To Local as "The external traffic from a remote network to a local network." L2R reverses the direction; L2L and R2R use the same locality for both ends.

    Reference: IBM QRadar 7.5 User Guide — Glossary, Remote To Local, p. 242

  9. 9An analyst creates a new custom dashboard in the standard Dashboard tab. What is its initial state?

    1. A.It is empty until the analyst adds itemsCorrect answer: A
    2. B.It starts with all default dashboard items
    3. C.It starts with the analyst's offense items
    4. D.It starts with all saved event search items

    Explanation: IBM states: "A new custom dashboard is empty by default; therefore, you must add items to the dashboard." It does not initially contain the other listed collections.

    Reference: IBM QRadar 7.5 User Guide — Chapter 3, Creating a custom dashboard, p. 24

  10. 10An analyst wants to find offenses using a custom property in the Offense Type list. Which prerequisite applies?

    1. A.The custom property must be used as a rule indexCorrect answer: A
    2. B.The custom property must be used only in a report
    3. C.The custom property must be a DateTime property
    4. D.The custom property must be excluded from rule indexes

    Explanation: IBM states: "The custom property must be used as a rule index." The offense source search does not support DateTime properties.

    Reference: IBM QRadar 7.5 User Guide — Chapter 10, Searching for offenses that are indexed on a custom property, p. 169
