IBM C1000-189 Sample Questions:

01. Infrastructure dashboards render promptly, but every view built on application data takes far longer than usual to return. When the data does arrive it is complete and up to date.

Which part of the backend does that combination point at?

a) The stage that extracts calls from the traces once they have been accepted

b) The queue that carries accepted payloads to the processing components

c) The ingress door that receives the payloads agents send

d) The gateway through which the application data is read out of its analytics store

02. No application call data at all is appearing for any service, while infrastructure charts stay current. The agents are connected, and the backend confirms that the payloads they send are being accepted and passed on.

What does that combination most directly implicate?

a) The stage that extracts the calls from traces after ingress has accepted them

b) The ingress component that receives the trace payloads the agents send

c) The component that reads beacons and sets the sampling decisions for them

d) The queue topic that carries the infrastructure metrics onward to the metrics processor

03. Beacon data is absent from every view that depends on it. Before changing anything, an administrator wants to establish whether the fault is at the door that receives beacons or at the stage that reads them afterward.

Which two observations would distinguish those two cases?

(Choose two.)

a) Whether the agent-facing ingress is accepting payloads, since all ingress into the backend shares one door

b) Whether the component that reads beacons from the queue is still consuming them, since a stalled reader leaves them queued rather than refused

c) Whether beacons are reaching the queue at all, since writing them there is what the receiving component does

d) Whether the processor that handles infrastructure metrics is still evaluating its event rules, since problems on the beacon path would surface there as events

04. Browser-side data is arriving and the beacon path reports no errors anywhere along it, but the number of user sessions recorded is visibly lower than the site's own traffic records suggest.

What is the most appropriate conclusion?

a) The reduced count can be expected behavior, because sampling decisions are set where beacons are read from the queue

b) The queue is discarding beacons, since it keeps only what the processor has time to read

c) Beacons are being dropped at the ingress door, because a path in good health would record every session that the site serves

d) The traffic records and the beacon count measure the same thing, so the difference is a defect in the browser instrumentation

05. Over the same period, host utilization charts have developed gaps and the event rules that watch infrastructure conditions have stopped firing. Application call data and browser data are both current.

Which single backend component best accounts for both symptoms at once?

a) The appdata-processor

b) The processor

c) The acceptor

d) The eum-processor

06. In a self-hosted backend, every ingress component reports that it is accepting payloads normally and nothing is being rejected, yet none of the three kinds of monitoring data has reached the long-term stores for some time.

Which three statements are consistent with that picture?

(Choose three.)

a) The read gateway for application data is the common stage that every kind of data passes through on its way to storage

b) Data is streamed to the backend for analysis before it is sent to the stores for long-term retention, so acceptance and storage are separate stages that can fail apart

c) Because all three kinds of data are affected together, a fault confined to one ingress door does not explain it

d) A stall in the queue that sits between ingress and processing would hold accepted payloads without rejecting them

e) The queue is itself the long-term store, so a stall there means the retained history has already been lost

07. A managed service provider runs Instana for several client organizations. Client data must not be visible across organizations, teams inside one client must see different parts of their own estate, and individual responders want views that suit the shift they work.

Which three place those separations at the right level?

(Choose three.)

a) Separating the teams inside one client is done by giving each team a backend of its own

b) What an individual responder looks at, shift by shift, is carried by the views that somebody scopes for them

c) Separating the teams inside one client is carried by the access their groups hold

d) Separating the client organizations is done by giving each client its own agents on the shared hosts

e) Separating one client organization from another is a tenant unit decision

08. New bundles have landed across a large fleet. The administrator wants to know whether the agents are now costing the monitored hosts more than they did before the update.

Which two statements describe how that has to be read?

(Choose two.)

a) The same pair of figures from before the update is needed for the comparison to mean anything

b) The agent process's own consumption is read against the volume of calls it handled over the same period

c) The total processor use on each host is the figure to compare, as it takes in everything the agents do there

d) A rise in consumption after the update is attributable to the new bundles, which are the only deliberate change

09. Access to Instana has been granted person by person as people asked for it. Joiners wait for somebody to notice them, and people who have moved on still hold what they were given.

How should the administrator hold that access instead?

a) Have the team lead approve each request that reaches the administrator, so that every grant made is a deliberate one somebody is accountable for

b) Grant it to groups and administer the membership, so that joining or leaving a team changes what a person holds

c) Issue one team account that the responders share, so that the access moves with the team rather than with the person

d) Give everybody the same broad read access, so that nobody is left waiting on a request

10. Every responder on a team keeps a private view assembled to their own taste. The administrator proposes authoring one dashboard and sharing it with the team instead.

What does sharing that authored dashboard buy them?

a) The data behind those signals is collected once for the team rather than once for each responder who looks at it

b) The signals on it are kept for longer than the ones on a private view

c) The team gains sight of entities that its access does not otherwise cover

d) Responders read the same signals during an incident
