Full question →mediummulti selectObjective-mapped
A CPU-bound batch rendering service runs on EC2. The application is Linux-based, compatible with ARM64, and the team wants the best throughput per dollar without changing the workload's architecture. Which two instance-family choices should the team consider first? Select two.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
A compute-optimized family, because it is designed for workloads that spend most of their time on CPU.
Compute-optimized families are the first place to look for sustained CPU-heavy jobs. They allocate more of the instance's resources to processor performance rather than memory or storage.
B
Best answer
A Graviton-based family, because compatible ARM instances often provide better price performance for many compute workloads.
Graviton instances can improve price performance when the software stack already runs on ARM64. Because the application is compatible with ARM64, this is a strong candidate for better throughput per dollar.
C
Distractor review
A memory-optimized family, because extra RAM always increases compute throughput.
Memory-optimized instances help when memory is the bottleneck, such as large in-memory databases or caching layers. They do not automatically improve a CPU-bound rendering workload.
D
Distractor review
A storage-optimized family, because local storage bandwidth is the main factor for rendering performance.
Storage-optimized families are useful when disk throughput or IOPS are the bottleneck. This scenario states that the workload is CPU-bound, so storage optimization is not the primary concern.
E
Distractor review
A burstable family, because CPU credits make sustained rendering faster during long runs.
Burstable instances are meant for baseline workloads with occasional CPU spikes. They are not a good fit for sustained batch rendering, where predictable CPU performance matters more than burst credits.
Common exam trap
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Technical deep dive
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
OSPF neighbours must agree on key parameters.
What is the correct answer to this question?
The correct answer is: A compute-optimized family, because it is designed for workloads that spend most of their time on CPU. — For a CPU-bound Linux workload that already supports ARM64, the two best first choices are a compute-optimized family and a Graviton-based family. Compute-optimized instances are built for sustained processor-intensive work, while Graviton often delivers better price performance for compatible applications. Those two directions address both raw throughput and cost efficiency without requiring an architectural rewrite. Memory-optimized and storage-optimized families solve different bottlenecks and are not the best fit for a CPU-heavy renderer. Burstable instances are designed for short spikes, not sustained compute-intensive processing. Since the workload is explicitly CPU-bound and ARM-compatible, compute-optimized Graviton-capable options are the right area to evaluate first.
