IBM C1000-156 Sample Questions:

01. A utility is preparing to onboard a controller model QRadar has never seen, and analysts will need to filter and report on the fields inside its events.

What has to be in place for those events to parse into usable fields?

a) A routing rule that forwards the controller events to a component able to interpret them

b) Raising the license allocation for the new devices, so the unfamiliar model has headroom of its own

c) Rebuilding the collection path so the controllers deliver through a supported protocol instead

d) Support for that event format, which arrives as a DSM

02. Why is payload investigation important when analyzing an offense?

a) It is the only part of an event that is retained after the offense closes, so it is where an analyst must look once an investigation has been dispositioned and reopened later.

b) It shows the raw record behind fields that parsing only summarizes.

c) It reveals which rules tested the event.

d) It shows how the record was routed through the deployment before storage.

03. A source was onboarded with the wrong type, and thousands of its records are now stored without recognized fields.

What should the team expect after correcting the type?

a) The deployment reparses the stored records automatically once the type is corrected.

b) Nothing changes, since the type is only a label applied for reporting.

c) Records arriving afterwards parse correctly, while those already stored remain as they were.

d) The stored records are removed, because they were never validly attributed to a source.

04. Each month-end, events become searchable several minutes after they occur. Collection keeps pace, search cost is unchanged, and the rule set has not been edited.

Which explanation best fits?

a) Month-end volume is raising the work the pipeline does, even though nothing about it changed.

b) The searches analysts run at month-end are scoped more broadly than usual.

c) The license entitlement is exceeded at month-end and the deployment throttles itself.

d) The rule set has become expensive without anybody editing it, because the building blocks it references now match more hosts.

05. A team proposes indexing every property, reasoning that if indexing makes searches faster then more indexing must be better. What is the flaw?

a) Indexing applies only to events, so flow searches would be unaffected and the team would see no benefit on half its data.

b) Indexing has its own cost, so indexing everything spends on properties nobody filters by.

c) Indexing changes the values stored, so some properties would become unusable.

d) Only properties supplied by the vendor may be indexed.

06. The same monthly report produced a noticeably different figure this month, although nobody edited its definition and the deployment reports itself healthy.

What should the administrator check first?

a) Whether the report’s period shifted, since a report summarizes only what its range admitted.

b) Whether the underlying saved search was replaced by another of the same name.

c) Whether the account that scheduled it still holds the same security profile.

d) Whether the deployment coalesced more records this month than last.

07. A deployment is being designed for an organization that expects its collected volume to grow substantially over three years, and the team is deciding where to spend first.

Which statement should guide that decision?

a) Growth should be met by raising the license entitlement before any appliance is added.

b) Adding storage capacity first is always correct, since every event that arrives has to be kept somewhere and growth is ultimately a storage problem.

c) Collection and processing scale separately, so whichever runs short first decides.

d) The Console should be scaled first, because all growth passes through it.

08. Analysts need a view they can watch through the day showing current activity across several categories at once. What fits?

a) An advanced search left running in a browser tab.

b) A dashboard assembled from saved searches.

c) A protected offense list, since protecting the offenses of interest keeps them present and therefore continuously visible to everyone on the team.

d) A scheduled report delivered hourly.

09. Events are being lost during the busiest part of the day. What distinguishes a license limit from a processing bottleneck as the cause?

a) A license limit appears gradually and a bottleneck appears instantly, so the two can be told apart simply by how suddenly the loss began.

b) A license limit produces unparsed events, because data over the entitlement is stored without being interpreted.

c) A license limit caps the rate the deployment is entitled to handle, while a bottleneck is a stage that cannot keep up.

d) A license limit affects flows only, whereas a bottleneck affects events only.

10. A deployment is being extended to a second site. The team proposes adding collection capacity there and processing everything centrally, and asks what the design has to account for.

Which consideration is most relevant?

a) Each site needs its own Console so that local administrators can work independently.

b) Events collected at the second site must be stored there before they can be processed centrally.

c) The second site’s data must use a separate license entitlement from the first.

d) The link between the sites has to carry the collected volume continuously, because processing happens away from where the data is gathered.
