NEW QUESTION # 112
Refer to the exhibit. An engineer must monitor the customer experience for an online banking application hosted in the private data center of the bank. Which ThousandEyes agent must the engineer deploy?
Answer: C
Explanation:
To monitor customer experience for an online banking application, the testing must simulate external, internet-based users accessing the bank's private data center.
Cisco ThousandEyes Cloud Agents run globally on the internet and provide the correct outside-in visibility required to measure real customer experience.
NEW QUESTION # 113
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?
Answer: A
Explanation:
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 to change 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 using Radio Resource Management (RRM) often automate this, but a manual adjustment based on SNMP telemetry is a valid operational fix.
NEW QUESTION # 114
Users at a remote corporate site (identified as s30 in the exhibit) are experiencing issues with a critical Enterprise Application hosted in the Data Center. The site connects to the central campus through an MPLS network.
The following exhibits show the network status before and after the issue began. Based on the information presented, what is the most likely cause of the problem and what actions would you take next as a Network Operations Engineer?
Answer: C
NEW QUESTION # 115
A network engineer is investigating widespread reports of poor performance for a data center-hosted web application. Which ThousandEyes agent type would be most effective for quickly identifying the root cause?
Answer: B
Explanation:
According to theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)guidelines, troubleshooting widespread performance issues for a public or data center-hosted app17lication requires an
"outside-in" perspective. When reports are widespread,18the goal is to determine if the issue is global, regional, or specific to certain ISP paths leading to the data center.
TheCloud Agent(Option D) is the most effective tool for this task because these agents are maintained by Cisco ThousandEyes in over 240+ locations worldwide within Tier 1, 2, and 3 ISPs and cloud provider regions.19Because they arepre-deployed and immediately available, a network engineer can instantly run tests from multiple global locations toward the data center-hosted application without having to install any software or manage any infrastructure. This allows the engineer to quickly compare performance metrics (latency, loss, and page load times) across different geographies. If Cloud Agents in London report no issues while those in New York report high packet loss, the engineer can immediately pinpoint the root cause as a regional ISP or peering issue rather than a failure within the data center itself.
* Enterprise Agent (Option B):While these could be used if they were already installed in various branch offices, they require ownership of the infrastructure and deployment time. They are better suited for "inside-out" monitoring.
* Endpoint Agent (Option C):These are useful for troubleshooting individual user experience but are not the "quickest" way to baseline global performance against a data center application during a widespread event.
* Synthetic Agent (Option A):As noted previously, this is a generic term describing the underlying technology used by all ThousandEyes agent types.
Therefore,Cloud Agentsprovide the necessary breadth and immediate availability to perform rapid root cause analysis for widespread application performance issues.
NEW QUESTION # 116
In endpoint agent deployment, what is the purpose of deploying agents on Room OS devices?
Answer: B
Explanation:
The purpose of deploying agents on Room OS devices is to monitor video conferencing performance, including audio and video quality, call connectivity, and conferencing reliability, to ensure optimal user experience and troubleshoot issues related to video conferencing applications and services.
