Question 160

After correcting the following problem, what result would best confirm success? Thousands of battery sensors send intermittent readings but have no reliable direct connection to cloud ingest endpoints.

  1. Forecasted total cost improves without tying unneeded capacity to an inflexible commitment.
  2. A regional recovery drill restores service within an hour with no more than five minutes of lost data.
  3. Representative messages retain business meaning without exposing protected customer information.
  4. After an offline interval, queued sensor messages arrive once connectivity returns without losing device identity.

Explanation

Correct Answer

D:

After an offline interval, queued sensor messages arrive once connectivity returns without losing device identity. This proves the service behavior rather than just showing a changed configuration. IoT gateways aggregate constrained device traffic and can isolate local protocols from cloud ingestion.

Incorrect Answers

A:

That approach would help when a stable database runs continuously year round but is billed at the highest on-demand compute rate. The required acceptance result is: After an offline interval, queued sensor messages arrive once connectivity returns without losing device identity.

B:

A regional recovery drill restores service within an hour with no more than five minutes of lost data. The relevant cloud response here is: After an offline interval, queued sensor messages arrive once connectivity returns without losing device identity.

C:

Representative messages retain business meaning without exposing protected customer information. The relevant cloud response here is: After an offline interval, queued sensor messages arrive once connectivity returns without losing device identity.

Question 161

The security administrator investigates: thousands of battery sensors send intermittent readings but have no reliable direct connection to cloud ingest endpoints. Which diagnostic inspection would isolate the immediate dependency?

  1. Check sensor link constraints, message acknowledgments, buffering and gateway authentication.
  2. Check the resource distribution, load-balancer health probes and fault-domain dependencies.
  3. Inspect language support, input privacy policy and error patterns.
  4. Check licensing scope, placement constraints and cluster failover requirements.

Explanation

Correct Answer

A:

Check sensor link constraints, message acknowledgments, buffering and gateway authentication. This distinguishes the relevant dependency before changing cloud resources. IoT gateways aggregate constrained device traffic and can isolate local protocols from cloud ingestion.

Incorrect Answers

B:

That approach would help when a customer portal runs on one VM in one fault domain and becomes inaccessible during localized infrastructure maintenance. Check sensor link constraints, message acknowledgments, buffering and gateway authentication.

C:

Inspect language support, input privacy policy and error patterns. The relevant cloud response here is: Check sensor link constraints, message acknowledgments, buffering and gateway authentication.

D:

Check licensing scope, placement constraints and cluster failover requirements. The relevant cloud response here is: Check sensor link constraints, message acknowledgments, buffering and gateway authentication.

Question 162

During an approved service change at a regional health provider, a bank must retain a regulated customer database on its premises while scaling a public cloud web tier for seasonal demand. Which action is the most targeted?

  1. Evaluate a community deployment with agreed membership, security and shared operating rules.
  2. Design a hybrid deployment with approved private connectivity and clear data boundaries.
  3. Use a governed private cloud within the approved facility.
  4. Select public cloud services matching its access, cost and scaling requirements.

Explanation

Correct Answer

B:

Hybrid deployments connect private and public environments but require explicit network, identity and compliance decisions. The change should be verified, not just applied: An end-to-end transaction succeeds without copying restricted records to public storage.

Incorrect Answers

A:

That approach would help when several research hospitals need a shared environment with sector-specific controls and a common governance charter. In this case, hybrid deployments connect private and public environments but require explicit network, identity and compliance decisions.

C:

Private clouds provide dedicated organizational environments but still require automation, capacity and lifecycle management. The relevant cloud response here is: Design a hybrid deployment with approved private connectivity and clear data boundaries.

D:

Public cloud offers shared-provider infrastructure with customer isolation and metered consumption. The relevant cloud response here is: Design a hybrid deployment with approved private connectivity and clear data boundaries.
