Cisco Designing and Implementing Enterprise Network Assurance 認定 300-445 試験問題 (Q97-Q102):

質問 # 97
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?

正解：D

解説：
In Designing 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 a Linux package on an organization's infrastructure, it is classified as an Enterprise Agent.
The correct configuration for this widget is Cloud & 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, the Mean (the arithmetic average) is the appropriate statistical measure.


質問 # 98
Refer to the exhibit. A network admin has been tasked with monitoring the IPv6 record and name server resolution times with different agents. Select the two actions that the engineer must take to meet the requirements.

正解：D、E

解説：
According to the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, DNS testing is a fundamental component of ensuring application availability and performance. The ThousandEyes platform provides two primary types of DNS tests: DNS Server and DNS Trace.
To satisfy the specific requirements of monitoring IPv6 records and name server resolution times, the engineer must utilize the DNS Server test. This test type is designed to measure the performance of specific DNS servers by querying them for particular resource records.
Monitoring IPv6 Records: In the DNS system, IPv6 address records are known as AAAA records.
Therefore, to monitor the availability and resolution of IPv6 addresses for a domain, the engineer must create a DNS Server test and set the query type to AAAA (Option B).
Monitoring Name Server Resolution Times: To measure how long it takes for a DNS server to return the authoritative name servers for a domain, the engineer must query for NS (Name Server) records. By creating a DNS Server test targeting the NS record (Option D), the platform can provide granular metrics on the response time and availability of those specific records from the perspective of the selected agents.


質問 # 99
Drag and Drop Question
Drag and drop the Cisco ThousandEyes integration types from the left onto the use cases on the right. Not all options are used.

正解：

解説：

Explanation:
Built-in integrations support direct alert delivery to collaboration tools like Slack.
Custom Webhooks allow forwarding alerts to systems like SolarWinds.
OpenTelemetry streams ThousandEyes metrics into observability tools such as Grafana.
SCIM API handles automated user provisioning from identity providers such as Active Directory.


質問 # 100
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?

正解：D

解説：
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.


質問 # 101
Refer to the exhibit. An engineer configured an agent-to-agent RTP test with the DSCP option set to EF between the office and the HQ to monitor voice quality. Users report intermittent voice quality issues. Which recommendation should the engineer make to improve voice quality?

正解：A

解説：
The RTP test was configured for EF (Expedited Forwarding), but the test results show the traffic is being received as Best Effort (DSCP 0). This means QoS marking is not being applied or preserved in the network. Without EF priority, packet loss and jitter increase, degrading voice quality. Marking (and honoring) EF resolves the issue.
