Ansible sudo error

When sudo ask method not working and /etc folder permission error.

We need to do below fix,

1) need to add 'sudo: yes' and 'become: yes' to all the task which need to run as root. 


- name: modify the resolv.conf
      sudo: yes
      become:yes
      copy:
        src: napa_resolv
        dest: /etc/resolv.conf
        backup: yes
        owner: root
        group: root
        mode: 0544
