Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q99-Q104):

NEW QUESTION # 99
A network monitoring engineer is tasked with creating a widget that displays the average packet loss from an agent installed as a Linux package. What is the data source and measure that should be selected?

Answer: D

Explanation:
InDesigning and Implementing Enterprise Network Assurance (300-445 ENNA), dashboard widgets must be mapped to the correct telemetry data source and statistical measure. When an agent is installed as aLinux packageon an organization's infrastructure, it is classified as anEnterprise Agent.
The correct configuration for this widget isCloud & Enterprise Agents and Mean(Option B).
* Data Source:Since the Linux-based agent is an Enterprise Agent, it shares the same data source category as Cloud Agents in the ThousandEyes dashboard configuration menu.
* Measure:To display the "average" packet loss as requested, theMean(the arithmetic average) is the appropriate statistical measure.
Other options are unsuitable:
* Option A:Endpoint Agentsare those installed on Windows/macOS user devices, not typically a standard Linux server package used for infrastructure monitoring.Medianwould show the middle value, not the average.
* Option C:Routingrefers to BGP data, which does not report packet loss in the same way as synthetic network tests.
* Option D:Devicesrefers to hardware monitored via SNMP, and annth Percentileis a specific statistical cutoff (like 95th percentile) rather than a simple average.


NEW QUESTION # 100
What is the primary purpose of synthetic web tests in network assurance?

Answer: A

Explanation:
The primary purpose of synthetic web tests is to simulate user interactions with web applications, facilitating performance monitoring and optimization in network assurance.


NEW QUESTION # 101
What is the primary purpose of synthetic web tests in network assurance?

Answer: A

Explanation:
The primary purpose of synthetic web tests is to simulate user interactions with web applications, facilitating performance monitoring and optimization in network assurance.


NEW QUESTION # 102
The alert shown in the exhibit is designed to detect which of the following network security issues?

Answer: A

Explanation:
As shown in Exhibit 4.1-1 (image_6e19fb.png), the alert rule is configured for the BGP layer with the name "AS origin AS 1234". The critical logic is defined in the Alert Conditions section, which specifies: BGP Origin meets all of: ASN not in 1234.
This specific configuration is the standard method used in ThousandEyes to detect BGP hijacking (Option C). BGP hijacking occurs when an unauthorized Autonomous System (AS) announces a network prefix that it does not own, effectively stealing the traffic meant for the legitimate owner.
By setting an alert that triggers when a monitored prefix is seen originating from an Autonomous System Number (ASN) that is not the expected authorized ASN (in this case, AS 1234), ThousandEyes provides immediate notification of a routing takeover.
Identifying this via BGP Origin alerts is superior to simple connectivity checks because it catches the issue at the routing control plane.


NEW QUESTION # 103
An administrator has set up GPO properly, but realized ThousandEyes EPA was not deployed on one of the office PCs. What is the appropriate first step?

Answer: A

Explanation:
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, troubleshooting deployment issues is as critical as the initial configuration. When utilizing Group 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.
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 to check 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.
