What is one fact about Cisco SD-Access wireless network deployments?
Show answer
Answer: A
Explanation
A is correct Access points must be deployed as follows: • Be directly connected to the fabric edge (or to an extended node switch) • Be part of the fabric overlay • Belong to the INFRA_VN, which is mapped to the global routing table • Join the WLC in Local mode WLCs must be deployed as follows: • Be connected outside the fabric (optionally directly to border) • Reside in the global routing table • No need for inter-VRF leaking for an AP to join the WLC • Communicate to only one control-plane node (two for redundancy); hence one WLC can belong to only one fabric domain (FD) https://www.cisco.com/c/dam/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/deploy-guide/cisco-dna-center-sd-access-wl-dg.pdf (page 10)

Question 316 · 1003 in bank
Which method creates an EEM applet policy that is registered with EEM and runs on demand or manually?
Show answer
Answer: A
Explanation
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/eem/command/eem-cr-book/eem-cr-e1.html EEM usually schedules and runs policies on the basis of an event specification that is contained within the policy itself. The event manager run command allows policies to be run manually. The event none command must first be configured to run the policy manually. The None Event Detector includes arguments when it publishes the none event. This command does not have a no form.

Question 318 · 1003 in bank
What is a requirement for an Ansible-managed node?
Show answer
Answer: A
Explanation
Ansible control machine (where you run Ansible from) and the managed nodes (where Ansible executes tasks) need to have SSH clients installed. However, the specific requirement I mentioned in my previous response is that the managed nodes must have an SSH server running, which is necessary for Ansible to establish connections and remotely manage those nodes. To clarify: -Ansible control machine: Requires an SSH client to establish connections to managed nodes. -Managed nodes: Require an SSH server to accept incoming connections from the Ansible control machine.

Question 319 · 1003 in bank
Which characteristic distinguishes Ansible from Chef?
Show answer
Answer: C
Explanation
Ansible works by connecting to your nodes and pushing out small programs, called ג€Ansible modulesג€ to them. These programs are written to be resource models of the desired state of the system. Ansible then executes these modules (over SSH by default), and removes them when finished. Chef is a much older, mature solution to configure management. Unlike Ansible, it does require an installation of an agent on each server, named chef-client. Also, unlike Ansible, it has a Chef server that each client pulls configuration from.

Explanation
My favorite: https://stackoverflow.com/questions/1619834/what-is-the-difference-between-declarative-and-procedural-programming-paradigms "Let me give you a real-world example: I need a cup of tea. Procedural: Go to kitchen Get sugar, milk, and tea, Mix them, and heat over the fire till it boils Put that in a cup and bring it to me Declarative: Get me a cup of tea. In a procedural language, you define the whole process and provide the steps how to do it. You just provide orders and define how the process will be served. In a declarative language, you just set the command or order, and let it be on the system how to complete that order. You just need your result without digging into how it should be done."
