NEW QUESTION # 106
An engineer must configure a wireless alert in the Cisco Meraki dashboard to send an email to support@cisco.
com when a gateway AP loses its link to the network and comes online as a repeater. What set of actions accomplishes these goals?
Answer: A
NEW QUESTION # 107
Exhibit:
An engineer works to optimize a website by reducing the page-load time to below 500 ms. The engineer set up a Cisco ThousandEyes page-load test to baseline the current website performance. Which action should be recommended to reduce page-load time?
Answer: B
Explanation:
In the context of Designing and Implementing Enterprise Network Assurance (300-445 ENNA) , analyzing page-load metrics within Cisco ThousandEyes requires identifying the primary bottlenecks that contribute to the Total Page Load Time . The provided screenshot displays a " Page Breakdown " of 7 resources totaling 953 kB. A critical observation of the pie chart reveals that Images (the teal-colored segment) constitute the vast majority of the page ' s payload and resource count.
When the goal is to reduce the page-load time from 1023 ms to below 500 ms , the engineer must target the heaviest components. Lazy loading is a design pattern that defers the initialization of non-critical resources at page load time. Instead of loading all images simultaneously when the user first navigates to the URL, lazy loading ensures that images are only downloaded as they are about to enter the viewport. This significantly reduces the initial DOM load time and the total Page Load Time because the browser does not have to wait for large image files to be fully retrieved before declaring the page " loaded. " Alternative options are less effective in this specific scenario based on the data:
* AJAX (XHR/Fetch): The chart shows that XHR and Fetch resources represent a negligible sliver of the total weight; optimizing them would yield minimal gains.
* Moving IMG elements: While moving scripts to the bottom can help with rendering, moving image elements to the bottom of the body does not stop the browser from initiating the download requests immediately, thus failing to significantly reduce the total load time.
* CDN for Fonts: The " Font " category is also a small fraction of the total 953 kB. While a CDN is a best practice for latency, it does not address the primary " weight " issue caused by the images.
Therefore, implementing lazy loading (Option C) is the most impactful recommendation. It directly addresses the largest resource consumer (Images) identified in the ThousandEyes Page Breakdown, allowing the engineer to reach the sub-500 ms performance target.
NEW QUESTION # 108
Your organization wants to be notified of an event as soon as it is triggered by an alert threshold.
This notification should be sent to your ITSM and generate an incident so it can be responded to appropriately. What kind of integration should you use?
Answer: C
Explanation:
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, the objective of modern network assurance is to bridge the gap between "visibility" and "action".
When an organization requires an automated workflow to handle network performance anomalies, the most efficient architecture is the native ServiceNow Integration (Option A). This integration is categorized as a "Custom-Built" or native integration within the ThousandEyes platform, designed specifically to facilitate the delivery of direct notifications into a ServiceNow account.
According to the ENNA implementation standards, the ThousandEyes ServiceNow integration utilizes the ServiceNow Incident Management module. When a predefined alert rule (such as a
5% packet loss threshold on a critical SaaS path) is violated, ThousandEyes triggers an event and immediately pushes the alert data to ServiceNow via an OAuth-authenticated connection.
Within ServiceNow, this data is used to automatically generate an Incident, complete with relevant metadata such as the test name, agent location, and the specific metrics that triggered the violation. This automation eliminates the manual overhead of "copy-pasting" alert details from a monitoring dashboard into a ticketing system, thereby significantly reducing the Mean Time to Identification (MTTI).
NEW QUESTION # 109 
Refer to the exhibit. An engineer is troubleshooting reported network delays that users are experiencing in Cisco Meraki. Which configuration must be implemented to resolve the issue?
Answer: B
NEW QUESTION # 110
