Complete the command to install Apache Airflow using pip.

Apache Airflow

pip install apache-airflow[1]

Drag options to blanks, or click blank then click option'

A--upgrade

Binstall

C==2.7.1

D--version

Attempts:

💡 Hint

Common Mistakes

Using 'install' after 'pip install' again causes an error.

Using '-upgrade' instead of '--upgrade' is incorrect syntax.

Using '--version' shows version info, not installs.

The correct way to specify a version when installing Airflow with pip is to use == followed by the version number.

Complete the command to initialize the Airflow database after installation.

Apache Airflow

airflow db [1]

Drag options to blanks, or click blank then click option'

Ainit

Bupgrade

Cinitdb

Dstart

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'start' tries to run the scheduler or webserver, not initialize DB.

Using 'initdb' is deprecated in newer Airflow versions.

Using 'upgrade' is for database migrations, not initial setup.

After installing Airflow, you run airflow db init to set up the database.

Fix the error in the command to start the Airflow webserver on port 8080.

Apache Airflow

airflow webserver [1] 8080

Drag options to blanks, or click blank then click option'

A--host

B-p

C-d

D--port

Attempts:

3 left

💡 Hint

Common Mistakes

Using '-p' is not recognized by Airflow webserver command.

Using '--host' sets the host, not the port.

Using '-d' is for daemon mode, not port.

The correct flag to specify the port for the Airflow webserver is --port.

Fill both blanks to create a virtual environment and activate it before installing Airflow.

Apache Airflow

python3 -m [1] airflow_env && source airflow_env/[2]

Drag options to blanks, or click blank then click option'

Avenv

Bbin/activate

CScripts/activate

Dvirtualenv

Attempts:

💡 Hint

Common Mistakes

Using 'virtualenv' instead of 'venv' is valid but less recommended in Python 3.

Using 'Scripts/activate' is for Windows, not Unix-like systems.

Forgetting to activate the environment causes package installs globally.

Use python3 -m venv to create a virtual environment and source airflow_env/bin/activate to activate it on Unix-like systems.

5fill in blank

hard

Fill all three blanks to set environment variables for Airflow home, initialize the database, and start the scheduler.

Apache Airflow

export AIRFLOW_HOME=[1] && airflow db [2] && airflow [3]

Drag options to blanks, or click blank then click option'

A"~/airflow"

Binit

Cscheduler

Dstart

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'start' instead of 'scheduler' will cause an error.

Not quoting the path can cause issues if it contains spaces.

Skipping database initialization causes scheduler to fail.

Set AIRFLOW_HOME to your Airflow folder, initialize the DB with init, then start the scheduler with scheduler.
