Amazon AWS Certified Solutions Architect - Associate SAA-C03 Practice Test 71

Question 700

A product team must receive a notification when its AWS monthly forecast crosses a spending threshold, before the final invoice arrives. Which service?

Configure AWS Budgets with a cost or usage budget and appropriate actual/forecast alert recipients.
Create a cost allocation tag but no budget thresholds, subscriber addresses or notification actions, and expect automatic forecasts.
Create only a Cost Explorer historical report and assume it automatically emails a threshold alert whenever a future monthly forecast crosses the budget.
Create an AWS Budget threshold but leave notification subscribers and actions empty, assuming alert delivery happens for every account by default.

Explanation

Correct Answer

Budgets compares observed/forecast spend to thresholds and sends alerts; a cost report alone is retrospective.

Incorrect Answers

Cost allocation labels are accounting dimensions; AWS Budgets needs an actual configured budget threshold and notification recipient.

Historical cost analysis is not a budget notification subscription. AWS Budgets needs a defined actual/forecast threshold and configured notification recipient.

A calculated threshold alone does not deliver the email or SNS alert. Configure notification recipients or supported actions and verify delivery.

Question 701

The CFO needs to identify which AWS service and activated cost allocation tag drove a last-month spending increase. Which cost analysis tool?

Use only a CPU utilization dashboard to allocate an AWS spend increase to activated resource tags and billing service dimensions.
Turn on raw resource tags today and assume Cost Explorer can reconstruct every prior untagged month under those same allocations.
Use AWS Cost Explorer grouped by service and activated cost allocation tag with the right date and charge dimensions.
Use AWS Budgets forecasts alone to identify each historical charge by service and tag without opening detailed usage or grouping views.

Explanation

Correct Answer

Cost Explorer explores charges and usage trends by relevant dimensions; tag activation and allocation quality matter.

Incorrect Answers

Compute telemetry does not provide the cost service/tag attribution that Cost Explorer can query from billing data.

Cost allocation tags must be activated and reflected in usable billing data; tags cannot retroactively supply missing historical dimensions for periods before tagging.

Budgets alerts track thresholds; Cost Explorer grouping by service and activated cost-allocation tags reveals the drivers of the previous month’s spend.

Question 702

A multi-account finance group needs per-resource hourly charge line items and an amortized view of Reserved Instance and Savings Plan commitments for chargeback. Which dataset?

Use AWS Cost and Usage Report or AWS Data Exports with appropriate detailed billing columns and amortization logic.
Rely on an EC2 instance type inventory without usage-line items and infer hourly amortized cost from the instance family names.
Use a single summary monthly invoice line as a substitute for resource-hour usage and amortized reservation allocation.
Export only the cash payment month of a one-year commitment and assign its entire cost to that month instead of allocating coverage across use.

Explanation

Correct Answer

Detailed line-item data distinguishes upfront commitment distribution from raw invoice cash flows.

Incorrect Answers

Inventory does not represent billing discounts, account dimensions, hourly records or RI/Savings Plans amortization.

Monthly invoice totals do not expose all the per-resource line items and amortization detail the chargeback team requires; use CUR/Data Exports with appropriate dimensions.

Cash payment timing is not the same as amortized eligible service usage; chargeback needs the amortized commitment columns and consumption attribution.

Question 703

An ECS cluster uses 24 large EC2 nodes but schedules only a few tiny tasks per host because requests and limits are oversized. Which change improves host spend per task?

Right-size task CPU/memory reservations and use efficient binpacking/placement after validating contention limits.
Keep every ECS task reserved at 8 vCPU and 32 GiB even though actual needs are tiny, and add more EC2 hosts to spread the excess.
Set an ECS EC2 task placement strategy to spread instances evenly across all AZs but never include a CPU or memory binpack preference, expecting spread alone to minimize idle host count.
Add more EC2 cluster instances before examining scheduler placement constraints from oversized task reservations.

Explanation

Correct Answer

Higher safe task density reduces wasted paid EC2 host resources while preserving application performance.

Incorrect Answers

Oversized task reservations reduce binpacking efficiency and increase idle host capacity; sizing should track peak task demand.

An AZ-spread strategy protects distribution but does not inherently pack tasks densely onto the fewest charged EC2 nodes. Right-sized task reservations plus appropriate binpacking controls are necessary for host utilization.

More hosts can hide the poor packing configuration and add cost. Examine resource reservations, placement strategies and observed service load first.

Question 704

A software vendor charges per physical CPU socket and permits BYOL only when the customer controls dedicated host placement. Which EC2 tenancy option?

Use a shared-tenancy EC2 instance without host placement visibility while treating any socket-based BYOL clause as automatically satisfied.
Evaluate Amazon EC2 Dedicated Hosts with host-based license management and measured utilization.
Use EC2 Dedicated Instances and assume they always expose the physical host socket identity and placement controls required by this BYOL contract.
Use ordinary shared-tenancy EC2 instances and present instance vCPU totals as evidence that the customer controls physical CPU sockets.

Explanation

Correct Answer

Dedicated Hosts give visibility/control over dedicated underlying server placement needed by some BYOL contracts.

Incorrect Answers

Per-socket license eligibility may require host-level control and matching instance placement, which Dedicated Hosts can support.

Dedicated Instances provide isolated tenancy, but host-level visibility and targeted placement generally require Dedicated Hosts for physical-socket license reporting.

Shared-tenancy vCPUs do not grant host identity or socket ownership; evaluate Dedicated Hosts and the vendor’s actual licensing eligibility terms.

Question 705

A CPU-heavy Lambda workload runs 20 seconds at 128 MB but only 3 seconds at 1024 MB; the team wants to lower total cost, not just memory allocated. Which process?

Choose the minimum Lambda memory setting without comparing longer runtime GB-seconds, claiming the smallest MB always costs least.
Purchase Lambda Provisioned Concurrency at the maximum required count and assume this optional always-warm capacity costs nothing while it is not invoked.
Increase Lambda memory blindly to the highest size and assume the fastest execution always yields the lowest dollar cost.
Benchmark total invocation GB-seconds and request count across memory settings, selecting the cheapest that meets latency SLO.

Explanation

Correct Answer

Higher memory can bring proportionally more CPU, so shorter runtime may offset the larger GB allocation.

Incorrect Answers

More memory includes proportional CPU and may reduce duration enough to lower total GB-second cost and meet SLOs.

Provisioned Concurrency is separately metered capacity. A response-time decision must account for the steady availability charge as well as duration, memory and requests; it cannot replace memory tuning for free.

Higher memory raises cost per unit of time; speed improvements must outweigh that rate. Test representative settings against both latency and total request cost.

Question 706

A container batch fleet runs on Spot instances and can checkpoint jobs. Which operational behavior reduces lost work as Spot capacity is reclaimed?

Use one Spot capacity pool in one AZ and disable checkpointing so worker restarts cannot repeat completed work.
Monitor Spot interruption/rebalance recommendations, checkpoint jobs and redistribute across diverse capacity pools.
Ignore Spot rebalance recommendations until the final instance termination and rely on local scratch disks to preserve unfinished jobs.
Disable job retries and constrain Spot jobs to one pool, assuming that prevents reclamation when capacity shifts.

Explanation

Correct Answer

Spot capacity rebalancing plus restartable application state mitigates interruptions but does not guarantee no reclaim events.

Incorrect Answers

A narrow Spot pool and nonrestartable jobs maximize interruption impact; diversify choices and make progress durable.

Spot capacity can be lost; checkpoint state must survive termination, and rebalance/interruption signals can trigger proactive draining or rescheduling.

Retries and diversified Spot capacity are resilience controls. Removing them increases permanent job loss and failed rescheduling under interruptions.

Question 707

An organization buys only EC2 Instance Savings Plans for m6i in us-east-1, then moves most workloads to Fargate. Why does the new usage get no equivalent discount?

An EC2 Instance Savings Plan purchased for one EC2 family automatically discounts every Fargate and Lambda execution in all Regions.
The EC2 Instance Savings Plan automatically extends its family commitment to Fargate tasks if the task CPU architecture matches m6i.
EC2 Instance Savings Plans are scoped to the chosen instance family and Region, unlike flexible Compute Savings Plans.
The unused EC2 Instance Savings Plan commitment is immediately cancelled and refunded once the original EC2 fleet migrates to Fargate.

Explanation

Correct Answer

A commitment must be matched to eligible usage; changing the workload can strand a restrictive purchase.

Incorrect Answers

That plan type is restricted to qualifying EC2 family/Region usage; it is not a cross-service Compute Savings Plan.

Fargate is eligible for Compute Savings Plans, not EC2 Instance Savings Plans, regardless of CPU architecture or the original m6i family.

Savings Plan commitments are term commitments rather than cancellable usage-based credits; changing to an ineligible service can strand the discount.

Question 708

A customer prepays for EC2 Instance Savings Plans restricted to a given family and moves its whole fleet to a different family. Why is the discount lost?

An EC2 Instance Savings Plan can follow a fleet to an arbitrary instance family without any change in effective eligible family/Region.
Size flexibility within one EC2 Instance Savings Plan also guarantees the discount for an unrelated EC2 instance family in that Region.
The changed family is outside the EC2 Instance Savings Plan family commitment scope.
An existing EC2 Instance Savings Plan can be exchanged at any time for a different family commitment without cost or coverage consequences.

Explanation

Correct Answer

Do not confuse size flexibility within the family with unrestricted cross-family coverage.

Incorrect Answers

The discount is scoped to a selected instance family in the specified Region; changes can leave the purchased commitment underused.

The eligible instance family is fixed for an EC2 Instance Savings Plan. Eligible size variation within a family does not imply unlimited cross-family coverage.

Savings Plan purchases are commitments rather than freely exchangeable family selections, so a family migration can leave the old commitment underutilized.

Question 709

An organization purchased a Compute Savings Plan for eligible EC2, Fargate and Lambda usage. Its Amazon RDS charges stay unchanged. Finance asks whether the same Compute Savings Plan can automatically cover its provisioned database instances. What is the correct scope distinction under current AWS Savings Plans?

An RDS Reserved Instance automatically follows any engine and class in every AWS Region without matching requirements.
Compute Savings Plans do not apply to RDS; evaluate eligible Database Savings Plans or database-specific Reserved Instance pricing separately under their own coverage and matching terms.
Adding the RDS identifier as a cost allocation tag automatically transfers the EC2 compute commitment to the database spend.
Converting the EC2 workload to a different family expands the Compute Savings Plan to cover all RDS classes without changing the commitment type.

Explanation

Correct Answer

Compute Savings Plans cover specified EC2, Fargate and Lambda usage, while AWS also offers separately scoped Database Savings Plans and eligible RDS Reserved Instance discounts.

Incorrect Answers

RDS RI benefits depend on eligible attributes and applicable flexibility rules, not universal cross-engine/Region coverage.

Cost allocation tags help attribution and reporting; they do not change the eligible-service list for an existing Savings Plan.

Compute Savings Plans have cross-instance-family flexibility within supported compute usage, not a universal extension to managed relational databases.

Question 710

A Spot instance is reclaimed with short notice and an uncheckpointed 12-hour job loses all progress. What design assumption failed?

The workload treated interruptible Spot capacity as guaranteed continuous compute without durable checkpoints.
Spot instances guarantee uninterrupted completion for the full 12-hour job whenever the purchase was placed during low-demand hours.
The Spot price fell during the job, which guarantees that any uncheckpointed application files will be recovered after capacity is reclaimed.
The batch worker had no second instance type configured, so the original reclaimed instance was obliged to finish its task uninterrupted.

Explanation

Correct Answer

Decouple job state from instance lifetime and use retry/checkpoint mechanisms or reserved capacity where necessary.

Incorrect Answers

Spot capacity can be reclaimed; the workload needs interruption-aware retries and durable progress even during off-peak periods.

Spot market pricing does not persist instance-local job state; interrupted jobs need durable progress and a restart path.

Capacity diversification improves replacement probability but cannot make an individual Spot instance interruption-proof; checkpoints remain necessary.
