NEW QUESTION # 21
What is the primary objective of synthetic testing in network assurance?
Answer: A
Explanation:
The primary objective of synthetic testing is to simulate user interactions with applications, enabling proactive monitoring and performance optimization in network assurance.
NEW QUESTION # 22
What is the purpose of recommending optimization for network capacity planning based on data interpretation?
Answer: A
Explanation:
The purpose of recommending optimization for network capacity planning based on data interpretation is to ensure scalability by identifying capacity bottlenecks, optimizing resource allocation, and planning for future growth and demand to maintain network performance and accommodate increasing workloads and traffic volumes.
NEW QUESTION # 23
You want to monitor Microsoft Teams using ThousandEyes endpoint agents. Which tests are available for this type of application monitoring?
Answer: B
Explanation:
According to theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)best practices for collaboration monitoring,Microsoft Teams(as well as Webex and Zoom) is monitored using a combination ofScheduled and Dynamic tests(Option D).
* Scheduled Tests:These are used to proactively monitor the reachability and performance of the Microsoft Teams infrastructure. The Teams template typically includes scheduled HTTP Server tests to teams.microsoft.com and login.microsoftonline.com, along with network-layer tests to theTeams Transport Relay(e.g., worldaz.tr.teams.microsoft.com). These provide a continuous baseline of connectivity regardless of whether a user is currently in a call.
* Dynamic Tests:These are a unique feature for collaboration monitoring. When an Endpoint Agent detects that the Teams application has initiated a real-time media session (audio or video call), it automatically triggers aDynamic Testto the specific IP and port being used for that call. This allows IT teams to see the exact network path-including hop-by-hop latency and loss-of the actual call traffic while the session is active.
Real User Tests (Option C)are generally not used for Teams monitoring in the same way they are for web- based SaaS apps. Because most users utilize the Teamsdesktop clientrather than the browser, the RUM browser extension cannot capture the rich telemetry of the desktop application's internal signaling and media streams. Therefore, the specialized "Automated Session Testing" provided byDynamic Tests, combined with the proactive health checks ofScheduled Tests, constitutes the complete assurance strategy for Microsoft Teams.
NEW QUESTION # 24
Review the exhibits. Based on the evidence, what seems to be the underlying issue?
Answer: D
NEW QUESTION # 25
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: D
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.
