You want to create an endpoint label that automatically includes all Endpoint Agents connected to...

In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) framework, managing a large-scale deployment of Endpoint Agents requires efficient categorization through Agent Labels . Agent labels are used to group agents for targeted test assignment and data filtering based on specific attributes like location, OS, or naming conventions.

ThousandEyes supports the use of wildcards (specifically the * symbol) within label filters to allow for dynamic and scalable grouping. In this scenario, the organization has adopted a naming convention of agentname-network. To capture all agents connected to the " corporate " network regardless of the unique agentname prefix, the engineer should use the filter *-corporate (Option A) in the hostname or agent name field. The asterisk functions as a placeholder for any string of characters, ensuring that any agent ending with " -corporate " is automatically added to the label as soon as it registers with the ThousandEyes platform.

Other options are incorrect for the following reasons:

agentname-* (Option B): This would only match agents that literally start with the string " agentname- " , which is a placeholder and not a representative filter for a group of uniquely named agents.

agent*corporate (Option C): This filter is overly broad and lacks the specific hyphen delimiter used in the organization ' s naming convention, potentially leading to the inclusion of unintended agents.

No wildcard (Option D): Wildcards are a documented and essential feature of the ThousandEyes label system to facilitate automated management in enterprise environments.

By implementing wildcard-based labels, the network administrator ensures that new agents are seamlessly integrated into the assurance strategy without the need for manual manual intervention.
