What type of alert rule configuration is used to monitor VPN connectivity issues affecting the end-user experience?
A. State-based rules
B. Throughput-based rules
C. Performance-based rules
D. Connectivity-based rules
答案:D
解題說明:
Connectivity-based rules are used to monitor VPN connectivity issues affecting the end-user experience by setting thresholds for VPN connection establishment times, packet loss rates, and latency to detect connectivity failures, disruptions, or degradation and trigger alerts for immediate investigation and resolution.
問題 #37
SNMP data indicates that a wireless access point is experiencing high channel utilization and increased retransmissions. What optimization would you recommend to improve voice call quality for users on this access point?
A. Change the access point to a different, less congested channel
B. Disable all non-voice traffic on the wireless network
C. Implement strict admission control for all wireless clients
D. Increase the transmit power of the access point
答案:A
解題說明:
In wireless network assurance, high channel utilization and increased retransmissions are clear indicators of RF interference or over-subscription. Retransmissions are particularly damaging to voice call quality because they introduce significant jitter and late-arrival packet loss that the jitter buffer cannot overcome.
The recommended optimization is tochange the access point to a different, less congested channel(Option B). This directly reduces the competition for airtime (Channel Utilization) and the likelihood of collisions from neighboring access points (Co-Channel Interference), which in turn lowers the retransmission rate.
Modern wireless controllers usingRadio Resource Management (RRM)often automate this, but a manual adjustment based on SNMP telemetry is a valid operational fix.
Other options are technically flawed:
* Option A:Increasing transmit power oftenincreasesinterference and channel utilization for surrounding cells, making the problem worse for everyone.
* Option Cisabling all non-voice traffic is an extreme measure that is rarely feasible in a real business environment.
* Option D:Admission control limits thenumberof users but doesn't solve the underlying issue of poor channel health for those already connected.
問題 #38
How does an endpoint agent contribute to network data collection?
A. Monitoring end-user devices
B. Configuring network protocols
C. Analyzing network traffic
D. Managing network infrastructure
答案:A
解題說明:
An endpoint agent contributes to network data collection by monitoring end-user devices and capturing relevant performance metrics for analysis.
問題 #39
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?
A. The agent is disabled
B. The agent is not running
C. The agent is still registering
D. The agent does not support Page load tests
答案:D
解題說明:
In the framework ofDesigning 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 testsandTransaction testsrequire 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 itdoes not support Page load tests(Option D). This common occurrence happens when an Enterprise Agent is deployed on resource-constrained hardware-such as certainCisco Catalyst 9000 switchesorCisco ISR 4000 series routers-where the Chromium browser package is either not supported or has not been enabled due to memory and CPU limitations.
When an agent lacks the required capabilities for a specific test layer (e.g., Web layer tests), it is automatically filtered out from the selection list in the ThousandEyes portal to prevent invalid test configurations. To identify compatible agents, an engineer can look for the "Browser" or "Dual Chromium" labels in the agent settings. If the "east1-agent-1" were merely offline (Option A), disabled (Option B), or still registering (Option C), it would typically still appear in the list but with a status indicator showing its unavailability, rather than being entirely hidden from the test assignment menu. Therefore, the absence of the agent in a web- layer test configuration explicitly indicates a lack of functional support for the required browser-based metrics.
問題 #40
What is the primary objective of diagnosing end-device network issues using collected data?
A. Identifying network vulnerabilities
B. Ensuring device compliance
C. Resolving connectivity issues
D. Optimizing server performance
答案:C
解題說明:
The primary objective of diagnosing end-device network issues using collected data is to identify and resolve connectivity issues affecting device performance and user experience.
