SQL Server DBA Interview Questions

Prepare one SQL Server story from a lab you can rebuild. This is not an exam.

This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.

What this hour is for

An interview question is useful when you can show the lab, the change, and the rollback. This page does not name a browser tool. The pillar it belongs to links the calculators for the neighbouring work. It does not list a bank of questions to memorize.

This is not an official certification and not a question dump. One story, from a database you administer or from a lab you built. Do not invent a production incident. Do not paste a live exam question.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep.

The change you can finish

Apply nothing while you are writing the note. When the lab window opens, it is one change on the database named in the ticket. Read the draft, then the database, then decide.

Rollback is the backup, the file, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.

  1. Pick one change you have done on a lab.
  2. Write what you observed.
  3. Write the rollback.
  4. Stop.

Mistakes that outlive the statement

SQL Server DBA Interview Questions goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.

Decisions to write down

One decision for SQL Server DBA Interview Questions: The lab is named. The change is named. The rollback is named. And no question dump is in the note.

Checks before you call it done

Confirm this before you call the change done: The lab is named. The change is named. The rollback is named. It is not an exam. And no secret is in the story. If one of those fails, stop.

# Interview practice. This page does not name a browser tool.
# Not an exam. Not a question dump.
# One story. Name the rollback.

Before you leave the database

SQL Server DBA Interview Questions ends when the database in the prompt is the database in the ticket. If it is not, you are on the wrong database. Stop.

The draft stays a draft until a person has read the names in it. A generator does not log into the database. You delete a line that names a host, a database, or an account you did not write down.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a database because a draft included them.

prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. A sample password in a draft is replaced. It is not a password you keep.

One change is the window. If two things move and the result is wrong, you will not know which one did it.

If the same step fails twice, stop for the day. Restore the copy you took first.

A second person reads the database name and the change aloud. If they cannot find them in the ticket, the note is not done.

This page is a planning guide. It is not a vendor manual, not an official standard, and not permission to touch a database you do not administer. You do not disable authentication, a firewall, or TLS to make a check pass.
