NEW QUESTION # 68
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: C
Explanation:
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.
NEW QUESTION # 69
Which agent type is responsible for conducting synthetic user interactions with web applications?
Answer: D,E
Explanation:
Synthetic user agents and scripting agents are responsible for conducting synthetic user interactions with web applications in network assurance, facilitating performance monitoring and testing.
NEW QUESTION # 70
An engineer is trying to configure a Page Load test and is trying to assign the east1-agent-1 to run it, but cannot see that agent listed. What is the reason that the designated agent does not appear?
Answer: C
Explanation:
In the framework of Designing and Implementing Enterprise Network Assurance (300-445 ENNA), selecting the appropriate agent for specific test types is a critical configuration step. The ThousandEyes platform utilizes different agent binaries and capabilities depending on the underlying hardware and software environment. Specifically, Page Load tests and Transaction tests require the agent to have a browser engine (Chromium) installed and functional to render web content and measure DOM-related metrics.
According to the ENNA implementation guidelines, not all Enterprise Agents support these browser- based tests. The exhibit displays a "New Test" configuration screen where the engineer is searching for "east1-agent-1". While other agents like "west-2-ag-1" are visible, the designated agent is missing because it does not support Page load tests (Option D). This common occurrence happens when an Enterprise Agent is deployed on resource-constrained hardware-- such as certain Cisco Catalyst 9000 switches or Cisco ISR 4000 series routers--where the Chromium browser package is either not supported or has not been enabled due to memory and CPU limitations.
NEW QUESTION # 71
How does Meraki Insights help in identifying latency issues across network segments?
Answer: C
NEW QUESTION # 72
Refer to the exhibit. A network administrator receives an incident report from a user who experienced voice and video quality issues with one of their Webex meetings. The administrator ran path visualization from Cisco ThousandEyes before and during the reported incident. What is the cause of the issue?
Answer: A
Explanation:
The "during-incident" path visualization shows packets repeatedly traversing the same ISP nodes, indicated by the red loop in the mid-path. This behavior is characteristic of a routing loop, which causes excessive delay and packet loss - directly impacting real-time applications such as Webex voice and video.
