PAS-C01 Design of SAP Workloads on AWS Practice Question
Exhibit
Refer to the exhibit.
{
"Rules": [
{
"SourceSecurityGroupId": "sg-12345",
"IpProtocol": "tcp",
"FromPort": 3300,
"ToPort": 3300
}
]
}An SAP administrator is troubleshooting connectivity between SAP application servers and the SAP HANA database. The database security group has an inbound rule as shown in the exhibit. The application servers are in security group sg-12345. However, the application servers cannot connect to the database. What is the most likely reason?
⚠ Common exam trap
It's easy for candidates to assume a security group rule referencing another security group is invalid or that the source must be an IP range, but AWS security groups can reference each other, and the real issue is typically a port mismatch or incorrect protocol.
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
✓
The port number is incorrect for SAP HANA.
SAP HANA uses TCP port 30015 by default for client connections (3<instance>15). If the security group inbound rule specifies a different port, such as 30013 or 31015, the application servers will be unable to establish a TCP connection to the database. The exhibit likely shows an incorrect port number, making option D the most likely cause.
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 source should be the IP address range of the application servers.
Why it's wrong here
Using security group is correct.
- ✗
The rule uses the wrong protocol; it should be UDP.
Why it's wrong here
SAP HANA uses TCP.
- ✗
The outbound rule on the application server security group is missing.
Why it's wrong here
Outbound rules are typically allow-all by default.
- ✓
The port number is incorrect for SAP HANA.
Why this is correct
SAP HANA uses port 3<instance_number>15, not 3300.
