問題 #19
You are tasked with creating a ThousandEyes transaction test to monitor the login process of a web application that uses SAML-based SSO with MFA. The MFA step involves a one-time password (OTP) generated by a mobile app. How can you configure the ThousandEyes test to successfully navigate this login process?
答案：A
解題說明：
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) framework, a common architectural hurdle is monitoring applications protected by Multi-Factor Authentication (MFA). ThousandEyes transaction tests utilize automated browser sessions to simulate user behavior, but they face inherent limitations when interacting with "out-of-band" security mechanisms.
Specifically, ThousandEyes agents cannot natively interact with external hardware tokens, biometric prompts, or mobile-app-based OTP generators (Option A). Since an OTP is dynamic and time-sensitive, manually entering it into a static test configuration (Option B) is impossible for an automated, recurring test. While some complex workhooks (Option C) might theoretically interface with a virtual MFA service, this introduces significant security risks and architectural complexity that is generally discouraged in a standard assurance design.
The verified and most practical approach is to exclude the MFA step from the transaction test and focus only on the SAML login (Option D). For monitoring purposes, IT teams often create a
"synthetic user" account within the Identity Provider (IdP) that is specifically exempted from MFA policies when originating from known ThousandEyes Enterprise Agent IP addresses. This allows the transaction script to validate the availability and performance of the SAML-based SSO redirect, the credential challenge, and the final application landing page. This strategy ensures that the network and application health can be baselined without the test being blocked by a security gate it was never intended to pass.
問題 #20
Refer to the exhibit.
Cisco ThousandEyes sent an alert that the bank website cannot be loaded in 10 seconds from the Sydney Cloud agent. What is the root cause of the website outage?
答案：C
問題 #21
A network engineer deploys a ThousandEyes Docker agent on a switch using app-hosting. The agent needs to communicate through a proxy server, but this configuration was missed during the initial deployment. The engineer adds the proxy settings to the app-hosting configuration. What is the next step to ensure the agent uses the proxy and appears online in the ThousandEyes portal?
答案：C
解題說明：
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)implementation guide, the Cisco IOS XEApplication Hostinglifecycle is a critical concept for troubleshooting and configuration management. When an application environment variable-such as proxy settings-is modified in the app-hosting configuration, a simple restart of the container is insufficient.
The correct procedure involves moving the application back to theConfiguredstate before bringing it back to Running. This requires a four-step lifecycle execution (Option C):
* Stop:Terminates the current running instance of the container.
* Deactivate:Releases the hardware resources (CPU, Memory, Virtual Interfaces) and, crucially, detaches the previous runtime configuration.
* Activate:Re-allocates the resources andinjects the new configuration parameters(including the updated proxy settings) into the container's environment.
* Start:Initiates the container with the newly applied configuration.
Without thedeactivate/activatesequence, the container will continue to use the environment variables present at the time of its initial activation, causing the agent to remain offline as it fails to reach the ThousandEyes portal without the proxy.Reinstalling(Option B) is an unnecessary and time-consuming step that involves re- downloading or re-copying the image, whileNo action(Option D) will result in no change to the agent's connectivity status.
問題 #22
Which monitoring method involves actively probing network devices and applications to collect data?
答案：C
解題說明：
Synthetic monitoring involves actively probing network devices and applications to collect data, as opposed to passive monitoring which observes network traffic passively.
問題 #23
An architect needs to analyze network path metrics from their internal network, specifically from the access layer to a cloud-hosted web server.1 Which ThousandEyes agent is most appropriate for this task?
答案：D
解題說明：
In the framework ofDesigning and Implementing En8terprise Network Assurance (300-445 ENNA), selecting the correct agent type depends heavily on the vantage point required for the specific observation. For this scenario, the architect must collect metrics from theinternal network access layer-the point closest to where the users or devices reside within the corporate perimeter-towards a cloud-hosted destination.
TheEnterprise Agent(Option B) is the most appropriate choice because it is specifically designed to be deployed on infrastructure owned and managed by the organization. These agents are "inside-out" vantage points that can be installed directly onCisco Catalyst 9300 or 9400 Series switchesat the access layer using Docker containers. By deploying an Enterprise Agent at the access layer, the architect gains visibility into the entire network path, starting from the internal LAN, traversing the edge/WAN, and reaching into the cloud- hosted web server. This allows for the identification of issues such as local congestion, ISP peering problems, or cloud provider latency.
Other options do not meet the criteria:
* Synthetic Agent (Option A):This is a distractor term. All ThousandEyes agents (Cloud, Enterprise, and Endpoint) are synthetic agents because they all perform active synthetic testing.
* Cloud Agent (Option C):These are pre-deployed by Cisco in global ISP data centers and provide an
"outside-in" view.14While useful for monitoring public-facing availability, they cannot provide visibility into the internal network or the access layer of the organization.
* Endpoint Agent (Option D):While these are installed on end-user machines and provide a "user- centric" view, they are generally not used for infrastructure-level path analysis from the access layer switches themselves.
Thus, theEnterprise Agentis the definitive choice for monitoring from the access layer to the cloud.
