Exam 350-901 topic 1 question 130 discussion

it´s D. C has no valid list for the loop

D is the correct answer.

Answer: D Note: A and B are eliminated, as collect_info is incorrect, it should be gather_facts. Note: gather_facts: no and gather_facts: false are equivalent [more explained about this later], so we must dig deeper to separate C and D. Digging further, they use different looping techniques. C uses the loop D uses with_items I see mistakes in both: C is doing it against a string instead of a list D is missing a colon on the with_items See below for additional reading [including why gather_facts: no and gather_facts: false are equivalent] As letsmeteennaam noted: C does not use a valid list structure. https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_loops.html per the link below, we should not get hung up on false versus no, as these are equivalent in ansible: gather_facts: no gather_facts: false https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_variables.html#boolean-variables

I find this on net: https://aap2.demoredhat.com/exercises/ansible_network/3-facts/ The gather_facts: no is required since as of Ansible 2.8 and earlier, this only works on Linux hosts, and not network infrastructure. We will use a specific module to gather facts for network equipment. As of we working with Switches no Linux I will go with C

What helped me with this question was understanding more about loops and with_* https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_loops.html As i was inclined to slect C, but as that does not contain a list, the right answer is D.

I think the answer is C because gather_facts should read false: https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_vars_facts.html#disabling-facts

Correct answer: D

D is correct: Only run against the switches inventory group. ✑ Execute from the local Ansible controller. - hosts: switches connection: local https://docs.ansible.com/ansible/latest/user_guide/playbooks_delegation.html ✑ Prevent the collection of system information prior to execution. gather_facts: no https://docs.ansible.com/ansible/2.9/modules/gather_facts_module.html#:~:text=This%20module%20is%20automatically%20called,facts%20about%20the%20system%2C%20automatically. ✑ Configure the VLANs and a name for each VLAN. nxos_vlan: vlan_id = {{ item.vid }} name = {{ item.name }} host {{ inventory_hostname }} state: present with_items vlan configuration https://docs.ansible.com/ansible/2.9/modules/nxos_vlans_module.html

- I believe it's "C", which is the only one with correct syntax for collecting info (gather_facts) and also boolean, which is wrong in other options. https://docs.ansible.com/ansible/latest/network/getting_started/first_playbook.html#gathering-facts-from-network-devices - As for VLAN naming, "C" looks pretty much like this: https://github.com/datacenter/Ansible-NXOS/blob/master/vlan_ansible.yml

D is correct: https://github.com/datacenter/Ansible-NXOS/blob/master/ADD_VXLAN_TENANT/roles/leaf/tasks/main.yml https://github.com/datacenter/Ansible-NXOS/blob/master/vlan_ansible.yml
