An engineer is troubleshooting the Ap join process using DNS. Which FQDN must be resolvable on the network for the access points to successfully register to the WLC?

1. A. wlcbostname.domain.com
2. B. cisco-capwap-controller.domain.com
3. C. ap-manager.domain.com
4. D. primary-wlc.domain.com

Correct Answer: B
DNS: If you have configured your DHCP server to provide both option 006 (DNS server address) and option 015 (domain name) information, the AP can obtain WLC addresses from the DNS server. The process works as follows:
* 1. The AP gets its IP address from DHCP with options 6 and 15 configured.
* 2. The AP can obtain the IP address of the DNS server from the DHCP option.
* 3. The AP uses this information to perform a hostname lookup using
CISCO-CAPWAP-CONTROLLER., which resolves to available WLC management interface IP addresses (IPv4 or IPv6, or both).
* 4. The AP can then perform a directed message to associate to responsive WLCs.
To prevent all APs from joining a single controller based on a DNS name resolution, the domain name may vary; this is what is done to dispatch APs to different controllers across the enterprise network, based on different domain names that are configured in their respective DNS scopes.

Drag and drop the characteristics from the left onto the technology types on the right.

Solution:
Orchestration
Orchestration means arranging or coordinating multiple systems. It’s also used to mean “running the same tasks on a bunch of servers at once, but not necessarily all of them.”
Configuration Management
Config Management is part of provisioning. Basically, that’s using a tool like Chef, Puppet or Ansible to configure our server. “Provisioning” often implies it’s the first time we do it. Config management usually happens repeatedly.
Configuration management (CM) is a systems engineering process for establishing and maintaining consistency of a product’s performance, functional, and physical attributes with its requirements, design, and operational information throughout its life Configuration management is all about bringing consistency in the infrastructure.
Configuration Orchestration vs Configuration Management
The first thing that should be clarified is the difference between “configuration orchestration” and “configuration management” tools, both of which are considered IaC tools and are included on this list.
Configuration orchestration tools, which include Terraform and AWS CloudFormation, are designed to
automate the deployment of servers and other infrastructure. Configuration management tools like Chef, Puppet, and the others on this list help configure the software and systems on this infrastructure that has already been provisioned.

Does this meet the goal?

1. A. Yes
2. B. No
