PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An SAP HANA database on EC2 is experiencing high I/O latency. The database uses a single EBS volume for /hana/log. The volume is a gp2 volume with 1000 GB size. The administrator notices that the volume's burst balance is depleted. Which action should be taken to improve latency?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change the volume type to Provisioned IOPS SSD (io1) with sufficient IOPS
Option D is correct because switching to io1 provides consistent IOPS without burst balance. Option A (increasing size) would increase baseline IOPS but not eliminate burst dependency. Option B (adding more volumes) may help but is more complex. Option C (using st1) is for throughput, not low latency.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Change the volume type to Throughput Optimized HDD (st1)
Why it's wrong here
st1 is for large sequential I/O, not low latency.
✗
Add additional gp2 volumes and stripe them in a RAID 0
Why it's wrong here
Striping helps throughput but each volume still has burst limits.
✗
Increase the volume size to 2000 GB to double the baseline IOPS
Why it's wrong here
Increasing size raises baseline IOPS but burst balance still depletes.
✓
Change the volume type to Provisioned IOPS SSD (io1) with sufficient IOPS
Why this is correct
io1 provides consistent IOPS without burst credits.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
