NEW QUESTION # 64
ThousandEyes offers several native integrations for receiving instant event notifications triggered by alerts.
Which of the following integrations are available directly within the ThousandEyes platform? Select all that apply.
Answer: A,B,D,E,F,G,H
Explanation:
According to theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA) architecture, ThousandEyes provides a suite of native, "out-of-the-box" integrations specifically designed for alert notifications. These integrations are configured via theManage > IntegrationsorAlert Rules > Notificationstabs and allow the platform to push instant event data to a variety of collaboration, IT operations, and observability tools.
The verified list of native notification integrations includes:
* ServiceNow (A):Facilitates direct incident management and automated ticketing workflows.
* PagerDuty (B):Allows for automated incident escalation and on-call routing based on ThousandEyes alerts.
* MS Teams (C) & Slack (H):Enable real-time chatops by pushing alert details and permalinks directly into specified channels for team collaboration.
* Splunk (D):Utilizes theCisco ThousandEyes App for Splunkto ingest alert data for historical analysis and correlation within a SIEM or logging platform.
* AppDynamics (F):Sends alert notifications directly into an AppDynamics instance, allowing application owners to correlate network issues with APM metrics.12
* Webex (G):Integrates with theWebex Control Huband specific Webex spaces to provide unified visibility for collaboration performance.34 AWS (Option E)is not a nativealert notificationdestination5in this context; instead, ThousandEyes integrates with AWS for "Cloud Insights" (ingesting VPC Flow Logs) and "Test Recommendations" rather than acting as a receiver for event notifications like a chat or ITSM tool. By utilizing these native integrations, enterprise teams ensure that the right stakeholders are notified through their preferred communication channels the moment a performance threshold is breached, drastically improving response times across the organization.
NEW QUESTION # 65
Refer to the exhibit. An engineer must use Cisco ThousandEyes testing to monitor their Cisco Catalyst SD-WAN fabric. Which SD-WAN component is being monitored by ThousandEyes?
Answer: B
Explanation:
The ThousandEyes Enterprise Agent is placed in the vEdge/vSmart/vManage transport VPN (VPN0), where it tests the Internet and MPLS transport paths directly. This means ThousandEyes is monitoring the underlay transport networks, not the SD-WAN overlay or IPsec tunnels.
NEW QUESTION # 66
An engineer needs to create a test that requires authentication configuration to monitor an API. The test must send a POST request with client credentials parameters to get a token. The token then needs to be sent out on a GET request to be authorized to get the resource.
What must be done to meet the requirements? (Choose two)
Answer: A,B
Explanation:
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, monitoring modern APIs often requires handling complex authentication flows, such as OAuth 2.0 with specific client credential parameters. The provided exhibit illustrates the HTTP Authentication options available within a standard HTTP Server test: None, Basic, NTLM, Kerberos, and OAuth.
According to the ENNA implementation standards, while the HTTP Server test type supports OAuth (Option C), its native implementation is limited. Specifically, it is designed to use a pre-existing token or a simple token refresh flow; it does not support the injection of custom parameters in the initial POST request required to obtain a token in many enterprise client-credential scenarios. Basic and NTLM (Options A and B) are legacy protocols that rely on simple username/password headers and cannot facilitate the multi-step token exchange process described.
To fulfill the requirement of a two-step flow (POST for token, followed by GET for resource), engineers must use more flexible test types:
* Transaction scripts (Option D): These allow the engineer to write custom JavaScript using the ThousandEyes transaction library to programmatically handle the POST request, parse the resulting JSON token, and then pass that token into the subsequent GET request ' s header.
* API tests (Option E): These are purpose-built for API monitoring and natively support the definition of variables and multi-step requests where the output of one call (the token) serves as the input for the next.
By utilizing these advanced test types, the engineer can successfully navigate complex authentication requirements that the standard HTTP Server test cannot accommodate.
NEW QUESTION # 67
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 ofDesigning and Implementing Enterprise Network Assurance (300-445 ENNA), analyzing page-load metrics within Cisco ThousandEyes requires identifying the primary bottlenecks that contribute to theTotal Page Load Time. The provided screenshot displays a "Page Breakdown" of 7 resources totaling 953 kB. A critical observation of the pie chart reveals thatImages(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 from1023 msto below500 ms, the engineer must target the heaviest components.Lazy loadingis a design pattern that defers the initialization of non-critical resources at page load time. Instead of loading all images simultaneously when the userfirst 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, implementinglazy 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.
