PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Exhibit
Refer to the exhibit.
Error log from SAP application server:
[ERROR] DBMS: SQL error: 1003 - 'ORA-01003: no statement parsed'
[ERROR] DBMS: SQL error: 1003 - 'ORA-01003: no statement parsed'
[ERROR] DBMS: SQL error: 1003 - 'ORA-01003: no statement parsed'
An SAP application server repeatedly logs the error above. The database is an Oracle RDS instance. What is the most likely cause of this error?
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.

Error log from SAP application server:
[ERROR] DBMS: SQL error: 1003 - 'ORA-01003: no statement parsed'

[ERROR] DBMS: SQL error: 1003 - 'ORA-01003: no statement parsed'
A
The SAP application server is misconfigured.
Why wrong: The error is from the application server but indicates a database issue.
B
The database connection is not properly established, or the session is in a bad state.
The error 'no statement parsed' typically occurs when a SQL statement is executed without a valid parse call, often due to connection issues.
C
There is a network connectivity issue between the application server and the database.
Why wrong: Network issues would typically cause timeout or connection refused errors.
D
The Oracle database is out of memory.
Why wrong: Out of memory errors are different, e.g., ORA-04031.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The database connection is not properly established, or the session is in a bad state.
The error about a SQL statement not being parsed before execution typically indicates a problem with the database connection or session state, which aligns with option B. Option A (misconfigured application server) would not directly cause this specific error. Option C (network connectivity) would manifest as timeout or connection failure, not a parsing error. Option D (out of memory) would cause different errors like ORA-04031. Therefore, the most likely cause is that the database connection is not properly established or the session is in a bad state.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PAS-C01 ACL questions on filtering logic and placement.
