    aws ec2 modify-hosts \
        --host-id h-06c2f189b4EXAMPLE \
        --auto-placement on

Output::

    {
        "Successful": [
            "h-06c2f189b4EXAMPLE"
        ],
        "Unsuccessful": []
    }

**Example 2: To enable host recovery for a Dedicated Host**

    aws ec2 modify-hosts \
        --host-id h-06c2f189b4EXAMPLE \
        --host-recovery on

    {
        "Successful": [
            "h-06c2f189b4EXAMPLE"
        ],
