Question 140
During a GreenLake design qualification, an HPE solution architect reviews this customer condition: Remote workloads are expected to continue local operations even when the cloud management console is temporarily unreachable. Which repeatable operational or governance practice best reduces this problem after the solution is delivered?
- Include restart and replica-failover tests for any stateful component.
- Test tenant separation, model access and retention before production.
- Report both measured RPO and RTO for each business service.
- Record offline control-plane limits in the availability plan.
Explanation
Correct Answer
D:Record offline control-plane limits in the availability plan. This practice targets the recurring root condition: management-plane connectivity and application execution can have different availability dependencies depending on architecture. Revisit the evidence (a disconnected test shows documented business processing continues while new management operations are delayed) to check that the agreed safe outcome remains sustained.
Incorrect Answers
A:Include restart and replica-failover tests for any stateful component. This option addresses a different situation (container stateless elasticity), in which web API containers scale horizontally but each replica incorrectly stores customer state on its own ephemeral local filesystem. It is not the best response here because management-plane connectivity and application execution can have different availability dependencies depending on architecture. The relevant diagnostic or acceptance evidence in this case concerns: a disconnected test shows documented business processing continues while new management operations are delayed.
B:Test tenant separation, model access and retention before production. This option addresses a different situation (large language model data locality), in which an AI team wants to fine-tune with sensitive documents but may not send training data to a public shared service. It is not the best response here because management-plane connectivity and application execution can have different availability dependencies depending on architecture. The relevant diagnostic or acceptance evidence in this case concerns: a disconnected test shows documented business processing continues while new management operations are delayed.
C:Report both measured RPO and RTO for each business service. This option addresses a different situation (disaster recovery RPO versus RTO), in which a customer asks for a five-minute recovery point but assumes that means the business application will be usable within five minutes too. It is not the best response here because management-plane connectivity and application execution can have different availability dependencies depending on architecture. The relevant diagnostic or acceptance evidence in this case concerns: a disconnected test shows documented business processing continues while new management operations are delayed.
Question 141
During a cloud platform proof of concept, an HPE solution architect reviews this customer condition: A VM migration is sized only from average CPU figures although the applications are paging heavily at the business peak. Which focused discovery or diagnostic step best establishes what the solution must address before committing to a design?
- Capture memory working-set, paging rate and peak CPU together.
- Measure cross-boundary data volumes and egress charges by processing job.
- Test application behavior with the WAN disconnected and measure maximum tolerable decision latency.
- Review colocation contract boundaries for power, cross-connects, physical access and managed services.
Explanation
Correct Answer
A:Capture memory working-set, paging rate and peak CPU together. It tests the case's specific issue (peak memory working set versus CPU utilization) without first changing unrelated components. The relevant mechanism is that average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The planned evidence or later validation reference is: telemetry shows paging spikes synchronized with response-time degradation.
Incorrect Answers
B:Measure cross-boundary data volumes and egress charges by processing job. This option addresses a different situation (cloud egress cost of analytics), in which a reporting application repeatedly reads several terabytes of private data back from a public-cloud location to an on-site analytics cluster. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.
C:Test application behavior with the WAN disconnected and measure maximum tolerable decision latency. This option addresses a different situation (edge sensor inference under outage), in which an automated manufacturing line must perform safety-related inference even when its WAN link is unavailable. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.
D:Review colocation contract boundaries for power, cross-connects, physical access and managed services. This option addresses a different situation (colocation managed custody), in which a customer needs hardware in a regional colocation facility and wants to distinguish hosting from operations responsibility. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.
Question 142
During an enterprise solution architecture review, an HPE solution architect reviews this customer condition: A VM migration is sized only from average CPU figures although the applications are paging heavily at the business peak. Which underlying technical principle most directly explains why the current plan risks missing the requirement?
- Multi-tenancy needs enforceable isolation in the management and resource planes, not just separate dashboard labels.
- Average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay.
- Comparison across incomplete cost boundaries can favor an option for reasons unrelated to true total cost.
- A snapshot sharing production administrative exposure may not survive an attacker who can delete or encrypt it.
Explanation
Correct Answer
B:Average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. This directly addresses the customer's stated behavior. Evidence to investigate or use for acceptance includes: telemetry shows paging spikes synchronized with response-time degradation.
Incorrect Answers
A:Multi-tenancy needs enforceable isolation in the management and resource planes, not just separate dashboard labels. This option addresses a different situation (multi-tenant blast radius), in which unrelated customers share management resources without clear tenant scoping for administrative actions. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.
C:Comparison across incomplete cost boundaries can favor an option for reasons unrelated to true total cost. This option addresses a different situation (cost comparison unit mismatch), in which a steering committee compares the monthly price of a cloud VM against an on-prem server purchase without support, facilities, licences or operations. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.
D:A snapshot sharing production administrative exposure may not survive an attacker who can delete or encrypt it. This option addresses a different situation (immutable cyber recovery copy), in which an organization relies on writable live snapshots alone as its ransomware recovery strategy. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.
Question 143
During a multi-site resilience design, an HPE solution architect reviews this customer condition: A VM migration is sized only from average CPU figures although the applications are paging heavily at the business peak. Which specific observation or test result would best confirm the suspected requirement or failure mechanism?
- A responsibility matrix identifies the client and provider owner for each control.
- A user from one tenant is denied access to another tenant's protected resources in test.
- Telemetry shows paging spikes synchronized with response-time degradation.
- An isolated recovery exercise restores data from a separately protected copy after production credentials are disabled.
Explanation
Correct Answer
C:Telemetry shows paging spikes synchronized with response-time degradation. This supplies a direct observation tied to the requirement instead of relying on unrelated metrics. The relevant technical principle is that average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay.
Incorrect Answers
A:A responsibility matrix identifies the client and provider owner for each control. This option addresses a different situation (shared responsibility confusion), in which a client expects a cloud consumption contract to relieve it automatically of application configuration and data classification duties. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.

Question 144
During a private cloud migration exercise, an HPE solution architect reviews this customer condition: A VM migration is sized only from average CPU figures although the applications are paging heavily at the business peak. Which specific architecture or implementation decision best addresses the stated customer condition?
- Design federation and scoped authorization rather than copying shared administrator credentials between clouds.
- Design local autonomy and recovery procedures for the exact control-plane failure case.
- Agree on the actual operating boundaries and assign an accountable party for each required control.
- Size host memory and compute using peak workload working sets and acceptable headroom.
Explanation
Correct Answer
D:Size host memory and compute using peak workload working sets and acceptable headroom. This responds to the stated requirement because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. Use the diagnostic or acceptance observation (telemetry shows paging spikes synchronized with response-time degradation) as a reference when confirming the corrected outcome.
Incorrect Answers
A:Design federation and scoped authorization rather than copying shared administrator credentials between clouds. This option addresses a different situation (hybrid identity portability), in which a company wants users to move between private and public workloads while maintaining access governance. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.
B:Design local autonomy and recovery procedures for the exact control-plane failure case.

Question 145
During a critical application architecture assessment, an HPE solution architect reviews this customer condition: A VM migration is sized only from average CPU figures although the applications are paging heavily at the business peak. Which repeatable operational or governance practice best reduces this problem after the solution is delivered?
- Revalidate sizing after major application or concurrency changes.
- Run periodic drift and orphan-resource reviews with named owners.
- Include restart and replica-failover tests for any stateful component.
- Test tenant separation, model access and retention before production.
Explanation
Correct Answer
A:Revalidate sizing after major application or concurrency changes. This practice targets the recurring root condition: average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. Revisit the evidence (telemetry shows paging spikes synchronized with response-time degradation) to check that the agreed safe outcome remains sustained.
Incorrect Answers
B:Run periodic drift and orphan-resource reviews with named owners. This option addresses a different situation (multi-cloud governance drift), in which teams deploy workloads into several clouds with different tags, backup policies and owner records. It is not the best response here because average CPU usage alone cannot establish a sufficient compute design when memory pressure drives the service delay. The relevant diagnostic or acceptance evidence in this case concerns: telemetry shows paging spikes synchronized with response-time degradation.

Question 146
During a regulated data-center refresh, an HPE solution architect reviews this customer condition: A steering committee compares the monthly price of a cloud VM against an on-prem server purchase without support, facilities, licences or operations. Which focused discovery or diagnostic step best establishes what the solution must address before committing to a design?
- Inspect whether backup retention and deletion privileges can be altered by compromised production identities.
- Normalize cost horizon and include all recurring and one-time components for each delivery model.
- Validate hypervisor and accelerator passthrough compatibility, licensing, and service-level latency.
- Identify operating-system, state, and service-discovery assumptions before selecting a target runtime.
Explanation
Correct Answer
B:Normalize cost horizon and include all recurring and one-time components for each delivery model. It tests the case's specific issue (cost comparison unit mismatch) without first changing unrelated components. The relevant mechanism is that comparison across incomplete cost boundaries can favor an option for reasons unrelated to true total cost. The planned evidence or later validation reference is: a line-item model shows omitted operating and network expenses change relative economics.
Incorrect Answers
A:Inspect whether backup retention and deletion privileges can be altered by compromised production identities. This option addresses a different situation (immutable cyber recovery copy), in which an organization relies on writable live snapshots alone as its ransomware recovery strategy. It is not the best response here because comparison across incomplete cost boundaries can favor an option for reasons unrelated to true total cost. The relevant diagnostic or acceptance evidence in this case concerns: a line-item model shows omitted operating and network expenses change relative economics.
C:Validate hypervisor and accelerator passthrough compatibility, licensing, and service-level latency. This option addresses a different situation (virtual machine versus bare metal), in which a licensed latency-sensitive workload needs direct accelerator and driver access while the default design assumes every service must be a VM. It is not the best response here because comparison across incomplete cost boundaries can favor an option for reasons unrelated to true total cost. The relevant diagnostic or acceptance evidence in this case concerns: a line-item model shows omitted operating and network expenses change relative economics.
D:Identify operating-system, state, and service-discovery assumptions before selecting a target runtime. This option addresses a different situation (cloud-native versus lift-and-shift), in which a legacy monolith is proposed for containers but has hardcoded node identities and writes session state to local disks. It is not the best response here because comparison across incomplete cost boundaries can favor an option for reasons unrelated to true total cost. The relevant diagnostic or acceptance evidence in this case concerns: a line-item model shows omitted operating and network expenses change relative economics.
