ThemaEinzelheiten
Thema 1
  • Data Collection Implementation: This domain focuses on deploying enterprise and endpoint agents across infrastructure and end-user devices. It covers configuring network, DNS, voice, web, and endpoint tests using ThousandEyes and Meraki Insights, along with implementing synthetic web tests and authentication methods.
Thema 2
  • Platforms and Architecture: This domain covers understanding monitoring agent types and placement, active versus passive monitoring, and ThousandEyes WAN Insights. It addresses Cisco platform integrations, metric baselines, and selecting appropriate integration methods and assurance platforms based on business requirements.
Thema 3
  • Insights and Alerts: This domain addresses configuring alert rules based on network conditions and end-user experience factors. It covers selecting metrics for stakeholders, validating alerts, and recommending network optimization for capacity planning.
Thema 4
  • Data Analysis: This domain encompasses diagnosing network issues like packet loss, congestion, routing, and jitter, plus end-device problems. It includes analyzing web application performance and identifying security threats such as DDoS attacks, DNS hijacking, and BGP hijacking.

Cisco Designing and Implementing Enterprise Network Assurance 300-445 Prüfungsfragen mit Lösungen (Q99-Q104):

99. Frage
An engineer configures a Cisco ThousandEyes dashboard to monitor application performance across different content delivery networks for a website. Drag and drop the configuration options from the bottom onto the boxes in the dashboard widget configuration to monitor the average time from the beginning of the first loaded object to the end of the final loaded object for the website.

Antwort:

Begründung:

Explanation:
Cloud and Enterprise Agents # Web - Page Load # DOM Load Time # Mean


100. Frage
Which RFC standardizes the concept of passive monitoring in network assurance?

Antwort: B

Begründung:
RFC 7799 standardizes passive monitoring methodologies, providing guidelines for data collection without affecting network traffic.


101. Frage
A corporation uses Cisco network devices. A network administrator must deploy a Cisco ThousandEyes Enterprise Agent to all corporate stores to monitor experience, but the administrator does not have servers or compute deployed. Which two agent deployment types would be the best fit for an edge retail location?
(Choose two.)

Antwort: A,E


102. Frage
Refer to the exhibit. Which integration type should be configured between ThousandEyes and Grafana?

Antwort: D

Begründung:
The example shows a POST request sent to /v7/stream, which is the ThousandEyes Streaming (Push) API used to push test metrics to external systems.
Grafana integrations with ThousandEyes rely on this Push API to receive data continuously for dashboards.


103. Frage
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?

Antwort: B

Begründung:
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)curriculum, understanding the visibility gap between the SD-WAN overlay and the transport underlay is a core competency. The provided exhibit illustrates a ThousandEyes Enterprise Agent deployed on aBranch Edge Routerperforming tests across two distinct paths:Internet(reaching a destination at 64.100.249.90) andMPLS (reaching a destination at 172.29.0.2).
According to the ENNA architecture guidelines, ThousandEyes is primarily utilized to provide hop-by-hop visibility into theunderlaynetwork. While SD-WAN controllers like vManage provide native monitoring for the overlay-the logical IPsec tunnels (Option B) that form the SD-WAN fabric-they often lack granular visibility into the physical service provider paths (the underlay) that carry those tunnels. The exhibit specifically highlights the agent probing the transport networks (Transport VPN0) directly, bypassing the overlay tunnels to measure the raw performance of the ISP and MPLS circuits.
By monitoring theunderlay(Option A), the engineer can identify if high latency or packet loss is caused by a specific hop within the service provider's infrastructure or at a peering point. This "underlay visibility" is critical for troubleshooting SD-WAN performance issues where the overlay may report a tunnel down, but the root cause lies in a BGP routing change or physical fiber cut in the provider network. ThousandEyes Enterprise Agents, natively integrated into Catalyst 8000 and ISR 4000 platforms, allow for this persistent underlay monitoring without additional hardware.
* Overlay (Option C):While ThousandEyes can monitor overlay performance, the exhibit's focus on the raw IP addresses (Internet and MPLS) in the transport VPN indicates an underlay test.
* IPsec/GRE Tunnels (Options B & D):These represent the transport mechanisms of the overlay.
ThousandEyes probes the pathunderthese tunnels to ensure the transport health is sufficient to support the fabric.
