Exam 200-901 topic 1 question 350 discussion

The delegate_to directive in the playbook specifies that the task should be delegated to the host srv-1a. This means the HSRP configuration tasks are executed from the srv-1a inventory host.

A. enabling HSRP on the nxos_rtr inventory host is incorrect because nxos_rtr starts the playbook, but HSRP is not configured on it. B. enabling HSRP on the rtr-1a inventory host is correct because host: "{{ hostvars['rtr-1a']['ansible_ssh_host'] }}" means that HSRP is configured on rtr-1a. C. executing HSRP configuration from the Ansible controller node is incorrect because delegate_to ensures that the configuration is not executed from the Ansible controller, but from srv-1a. D. executing HSRP configuration from the srv-1a inventory host is incorrect because srv-1a executes the playbook, but HSRP is not configured on srv-1a, it is applied on rtr-1a.

The Playbook Targets rtr-1a, Not nxos_rtr: task in the playbook is specifically targeting rtr-1a for HSRP configuration. The line: host: "{{ hostvars['rtr-1a']['ansible_ssh_host'] }}"

Host doesn’t seem to be a valid parameter. In that case only answer A is valid looking at the group that is being targeted. https://docs.ansible.com/ansible/latest/collections/cisco/nxos/nxos_hsrp_module.html

i think "gather_facts: false" is the key in this question and https://docs.ansible.com/archive/ansible/2.5/modules/nxos_hsrp_module.html
