Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q37-Q42):

NEW QUESTION # 37
In the IT operations dashboard, what is the alert trigger reason?

Answer: C

Explanation:
Detailed Explanation:
The IT Operations Dashboard includes a section at the beginning that explicitly displays active alert rules and their status. According to the dashboard configuration, the reason for the current alert trigger is Network packet loss. This indicates that the underlying network path for the application is experiencing packet drops exceeding the defined threshold, even if the application layer remains partially functional.


NEW QUESTION # 38
Review the exhibits. Based on the evidence, what seems to be the underlying issue?

Answer: A


NEW QUESTION # 39
An administrator has set up GPO properly, but realized ThousandEyes EPA was not deployed on one of the office PCs.9 What is the appropriate first step?

Answer: D

Explanation:
In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)curriculum, troubleshooting deployment issues is as critical as the initial configuration. When utilizingGroup Policy Objects (GPOs)for the distribution of the ThousandEyes Endpoint Agent (EPA), certain prerequisites must be met for the policy to take effect on a target machine.10 The most fundamental requirement is that the target PC must be a member of the domain or the specific Organizational Unit (OU) where the GPO is linked. Therefore, the appropriate first step is tocheck that the PC belongs to the needed domain(Option B). GPOs are scoped based on Active Directory membership; if a computer is in a workgroup or a different domain/OU that is not targeted by the policy, it will never receive the instruction to install the software, regardless of how "properly" the GPO is configured on the server.11 The other options are technically incorrect or represent a misunderstanding of GPO mechanics:
* Administrator Login (Option A):EPA installation via GPO is typically configured to run under the System account context during startup, meaning it is not dependent on a specific user (administrator or otherwise) logging in to trigger the deployment.
* Rebooting to restart GPO on the server (Option C):Rebooting a client PC triggers a "GPUpdate" request from the client to the server, but it does not "restart" the GPO service on the server side.
* Rebooting the Server (Option D):This is an invasive and unnecessary step that will not force a policy update on a specific client PC if that PC is not correctly joined to the domain or is experiencing a local networking issue.
By verifying domain membership first, the administrator ensures the basic trust and communication path required for GPO delivery is functional before moving to more complex troubleshooting steps like checking event logs or network connectivity.


NEW QUESTION # 40
In network assurance, what is the purpose of a local collection agent?

Answer: D

Explanation:
The purpose of a local collection agent is to gather data from nearby devices within the same network segment, enabling detailed monitoring and analysis of local traffic patterns.


NEW QUESTION # 41
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: C

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 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 C:Disabling 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.
