PAS-C01 Operations and Maintenance Practice Question
An SAP administrator is troubleshooting a network connectivity issue between an SAP application server and an SAP HANA database, both running on EC2 in the same VPC. The security groups allow traffic on port 3xx15 and 3xx17. Which TWO steps should the administrator take to diagnose the problem?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the route tables to ensure the subnets can communicate.
Options C and E are correct. Checking route tables (C) ensures that the subnets can communicate within the VPC. Verifying network ACLs (E) is important because NACLs are stateless and can block traffic even if security groups allow it. Option A is incorrect because security groups are stateful and automatically allow return traffic for allowed inbound traffic. Option B is incorrect because an internet gateway is not needed for internal VPC traffic. Option D is incorrect because VPC Flow Logs are useful for analysis but not the first step; immediate checks should focus on ACLs and route tables.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Check that the security groups have outbound rules that allow return traffic.
Why it's wrong here
Security groups are stateful, so outbound rules are not needed for return traffic.
- ✗
Ensure the internet gateway is attached to the VPC.
Why it's wrong here
Internet gateway is not needed for internal communication within the same VPC.
- ✓
Check the route tables to ensure the subnets can communicate.
Why this is correct
Route tables must have routes for intra-VPC communication.
- ✗
Enable VPC Flow Logs and analyze logs for dropped packets.
Why it's wrong here
Flow Logs are useful but more for deep analysis; first check basic configurations.
- ✓
Verify that the network ACLs for both subnets allow the required traffic.
Why this is correct
NACLs can block traffic; verifying them is a key step.
