Question 90
During a regulated data-center refresh, an HPE solution architect reviews this customer condition: A customer needs hardware in a regional colocation facility and wants to distinguish hosting from operations responsibility. Which repeatable operational or governance practice best reduces this problem after the solution is delivered?
- Include data movement, egress pricing, and network capacity in placement comparisons.
- Confirm remote hands, escalation windows and access controls before go-live.
- Use dependency mapping and restart tests before making modernization commitments.
- Include disconnected-mode test cases and model update procedures in acceptance criteria.
Explanation
Correct Answer
B:Confirm remote hands, escalation windows and access controls before go-live. This practice targets the recurring root condition: a colocation provider supplies facilities but does not necessarily own guest OS or application operations. Revisit the evidence (the signed service matrix shows which party manages each layer) to check that the agreed safe outcome remains sustained.
Incorrect Answers
A:Include data movement, egress pricing, and network capacity in placement comparisons. 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 a colocation provider supplies facilities but does not necessarily own guest OS or application operations. The relevant diagnostic or acceptance evidence in this case concerns: the signed service matrix shows which party manages each layer.
C:Use dependency mapping and restart tests before making modernization commitments. 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 a colocation provider supplies facilities but does not necessarily own guest OS or application operations. The relevant diagnostic or acceptance evidence in this case concerns: the signed service matrix shows which party manages each layer.
D:Include disconnected-mode test cases and model update procedures in acceptance criteria. 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 a colocation provider supplies facilities but does not necessarily own guest OS or application operations. The relevant diagnostic or acceptance evidence in this case concerns: the signed service matrix shows which party manages each layer.
Question 91
During an edge-to-core operating-model assessment, an HPE solution architect reviews this customer condition: The team calls two racks in the same flood-prone building separate disaster recovery sites. Which focused discovery or diagnostic step best establishes what the solution must address before committing to a design?
- Identify supported API resources, authentication scopes and idempotent workflow boundaries.
- Inspect the application access API and lifecycle/retention requirements.
- Map correlated failure domains, physical utilities, connectivity, and geographic hazards.
- Document catalog offerings, quotas, approvals and guest lifecycle responsibilities.
Explanation
Correct Answer
C:Map correlated failure domains, physical utilities, connectivity, and geographic hazards. It tests the case's specific issue (service availability zone semantics) without first changing unrelated components. The relevant mechanism is that rack separation does not provide site-level disaster resilience against a shared physical event. The planned evidence or later validation reference is: failure-domain analysis shows both racks depend on the same building and upstream utilities.
Incorrect Answers
A:Identify supported API resources, authentication scopes and idempotent workflow boundaries. This option addresses a different situation (API-first provisioning reliability), in which the operator wants repeatable tenant provisioning across environments but currently performs undocumented console clicks. It is not the best response here because rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
B:Inspect the application access API and lifecycle/retention requirements. This option addresses a different situation (object data for application media), in which a digital archive retrieves media through identifiers and metadata with no expectation of mounting block devices. It is not the best response here because rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
D:Document catalog offerings, quotas, approvals and guest lifecycle responsibilities. This option addresses a different situation (private cloud self-service boundaries), in which a company needs internal teams to request VMs from a catalog while platform owners retain capacity and policy control. It is not the best response here because rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
Question 92
During a customer deployment readiness meeting, an HPE solution architect reviews this customer condition: The team calls two racks in the same flood-prone building separate disaster recovery sites. Which underlying technical principle most directly explains why the current plan risks missing the requirement?
- Network reachability by default creates lateral-movement paths unless rules enforce allowed communication.
- Object storage exposes object identifiers and metadata instead of host-managed blocks or normal SMB file ownership.
- Self-service provisioning can coexist with centralized governance when templates and quotas enforce policy.
- Rack separation does not provide site-level disaster resilience against a shared physical event.
Explanation
Correct Answer
D:Rack separation does not provide site-level disaster resilience against a shared physical event. This directly addresses the customer's stated behavior. Evidence to investigate or use for acceptance includes: failure-domain analysis shows both racks depend on the same building and upstream utilities.
Incorrect Answers
A:Network reachability by default creates lateral-movement paths unless rules enforce allowed communication. This option addresses a different situation (network segmentation and microsegmentation), in which many business applications share one trusted subnet even though their east-west communications must be limited. It is not the best response here because rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.

The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
Question 93
During a GreenLake design qualification, an HPE solution architect reviews this customer condition: The team calls two racks in the same flood-prone building separate disaster recovery sites. Which specific observation or test result would best confirm the suspected requirement or failure mechanism?
- Failure-domain analysis shows both racks depend on the same building and upstream utilities.
- Data-flow and location evidence establishes where each live and backup copy resides.
- End-to-end tests show user transactions can fail during network outage even if stored data is intact.
- Test results show latency changing under the representative database workload before capacity is exhausted.
Explanation
Correct Answer
A:Failure-domain analysis shows both racks depend on the same building and upstream utilities. This supplies a direct observation tied to the requirement instead of relying on unrelated metrics. The relevant technical principle is that rack separation does not provide site-level disaster resilience against a shared physical event.
Incorrect Answers
B:Data-flow and location evidence establishes where each live and backup copy resides. This option addresses a different situation (regulated in-country data custody), in which a public agency must keep classified records inside a defined legal jurisdiction with strict physical and administrative access controls. It is not the best response here because rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
C:End-to-end tests show user transactions can fail during network outage even if stored data is intact. This option addresses a different situation (storage durability versus service uptime), in which a proposal uses high storage durability claims as proof that the application meets its 99.95% availability objective. It is not the best response here because rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
D:Test results show latency changing under the representative database workload before capacity is exhausted. This option addresses a different situation (application database IOPS sensitivity), in which a transactional application has strict p99 write latency targets and is being proposed on a storage tier selected only by terabyte price. It is not the best response here because rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
Question 94
During an infrastructure cost and risk review, an HPE solution architect reviews this customer condition: The team calls two racks in the same flood-prone building separate disaster recovery sites. Which specific architecture or implementation decision best addresses the stated customer condition?
- Evaluate placing compute near the data or keeping the stable data-intensive workload in a private environment.
- Design a genuinely separate recovery location or accept the documented correlated risk.
- Choose a supported VM migration first or refactor dependencies before containerization.
- Place the inference runtime at the edge with centrally managed model distribution when connectivity returns.
Explanation
Correct Answer
B:Design a genuinely separate recovery location or accept the documented correlated risk. This responds to the stated requirement because rack separation does not provide site-level disaster resilience against a shared physical event. Use the diagnostic or acceptance observation (failure-domain analysis shows both racks depend on the same building and upstream utilities) as a reference when confirming the corrected outcome.
Incorrect Answers
A:Evaluate placing compute near the data or keeping the stable data-intensive workload in a private environment. 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 rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
C:Choose a supported VM migration first or refactor dependencies before containerization. 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 rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.

Question 95
During a hybrid cloud requirements workshop, an HPE solution architect reviews this customer condition: The team calls two racks in the same flood-prone building separate disaster recovery sites. Which repeatable operational or governance practice best reduces this problem after the solution is delivered?
- Record hardware compatibility and licensing assumptions in the design decision.
- Include data movement, egress pricing, and network capacity in placement comparisons.
- Review geographic and utility dependencies during resilience design.
- Use dependency mapping and restart tests before making modernization commitments.
Explanation
Correct Answer
C:Review geographic and utility dependencies during resilience design. This practice targets the recurring root condition: rack separation does not provide site-level disaster resilience against a shared physical event. Revisit the evidence (failure-domain analysis shows both racks depend on the same building and upstream utilities) to check that the agreed safe outcome remains sustained.
Incorrect Answers
A:Record hardware compatibility and licensing assumptions in the design decision. 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 rack separation does not provide site-level disaster resilience against a shared physical event. The relevant diagnostic or acceptance evidence in this case concerns: failure-domain analysis shows both racks depend on the same building and upstream utilities.
B:Include data movement, egress pricing, and network capacity in placement comparisons. 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.

Question 96
During a multi-site resilience design, an HPE solution architect reviews this customer condition: A proposal uses high storage durability claims as proof that the application meets its 99.95% availability objective. Which focused discovery or diagnostic step best establishes what the solution must address before committing to a design?
- Compare measured I/O sizes, write mix, queue depth, and p99 latency under realistic concurrency.
- Validate client protocols and concurrent file access semantics with representative users.
- Identify supported API resources, authentication scopes and idempotent workflow boundaries.
- Separately inspect data-loss protection and total service dependencies including compute/network/identity.
Explanation
Correct Answer
D:Separately inspect data-loss protection and total service dependencies including compute/network/identity. It tests the case's specific issue (storage durability versus service uptime) without first changing unrelated components. The relevant mechanism is that data durability describes preservation of data whereas application availability depends on every service in the transaction path. The planned evidence or later validation reference is: end-to-end tests show user transactions can fail during network outage even if stored data is intact.

Which underlying technical principle most directly explains why the current plan risks missing the requirement?
- Data durability describes preservation of data whereas application availability depends on every service in the transaction path.
- A general statement that a service is cloud hosted does not prove the location and access limits required by the agency.
- Network reachability by default creates lateral-movement paths unless rules enforce allowed communication.
- A shared file protocol provides file-level namespace and access controls unlike independent raw-block access.
Explanation
Correct Answer
