This PAS-C01 practice question tests your understanding of technology. 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.
Exhibit

2023-05-15T10:30:00Z ERROR [pool-12-thread-1] com.sap.hana.di: Rowid: 12345, Error: 100 Could not execute 'INSERT INTO "SAPSR3"."BKPF" VALUES ( ... )' SQLState: 42000: [SAP AG][LIBODBCHDB SOAP][HDBODBC] General error;258: authentication failed: invalid user or password
An SAP HANA administrator sees the error log entry shown in the exhibit. The error occurs when a scheduled job tries to insert data into the BKPF table. What is the MOST likely cause?
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.

A
The credentials used by the scheduled job are incorrect.
The error message explicitly says invalid user or password.
B
The user does not have INSERT privilege on the BKPF table.
Why wrong: The error is about authentication, not privileges.
C
The SQL statement has a syntax error.
Why wrong: The error is authentication-related, not syntax.
D
The table BKPF is full and cannot accept new rows.
Why wrong: The error does not indicate a space issue.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The credentials used by the scheduled job are incorrect.
Option C is correct because the error message clearly states 'authentication failed: invalid user or password'. Option A is incorrect because there is no indication of missing privileges. Option B is incorrect because the error is not about table space. Option D is incorrect because the statement is an INSERT, not a SELECT.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PAS-C01 questions on access control and AAA configuration.
