This PAS-C01 practice question tests your understanding of migration. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company is migrating an SAP ERP system to AWS using the SAP Landscape Virtualization Management (LVM) tool. During the migration, the team encounters a timeout error when replicating the database. The source database is an SAP HANA multi-tenant database container (MDC) system. What is the most likely cause of the timeout?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SSH session between LVM and the target server timed out due to a missing ServerAliveInterval setting
Option C is correct because LVM uses SSH for communication; if the SSH session times out due to inactivity, the replication fails. Option A is incorrect because LVM does not require SCT. Option B is incorrect because HANA MDC is supported by LVM. Option D is incorrect because the migration does not require an SAP router.
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.
✗
The SAP Landscape Virtualization Management (LVM) agent is incompatible with the SAP HANA version
Why it's wrong here
LVM supports multiple HANA versions; incompatibility is less likely than network issues.
✗
The SAP HANA multi-tenant database container (MDC) configuration is not supported by LVM
Why it's wrong here
LVM supports MDC environments.
✓
The SSH session between LVM and the target server timed out due to a missing ServerAliveInterval setting
Why this is correct
LVM uses SSH; without keep-alive settings, idle SSH sessions can timeout during long-running operations.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
The SAP Router is not configured to forward traffic between the source and target
Why it's wrong here
SAP Router is not required for LVM-based migrations.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
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.
Migration — This question tests Migration — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: The SSH session between LVM and the target server timed out due to a missing ServerAliveInterval setting — Option C is correct because LVM uses SSH for communication; if the SSH session times out due to inactivity, the replication fails. Option A is incorrect because LVM does not require SCT. Option B is incorrect because HANA MDC is supported by LVM. Option D is incorrect because the migration does not require an SAP router.
What should I do if I get this PAS-C01 question wrong?
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.
Are there clue words in this question I should notice?
Yes — watch for: "most likely". Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
