Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q17-Q22):

NEW QUESTION # 17
What optimization recommendation is commonly made for network capacity planning based on data interpretation?

Answer: C

Explanation:
Topology changes are commonly recommended for network capacity planning based on data interpretation to optimize network performance and address scalability requirements.


NEW QUESTION # 18
Which condition requires the use of Cisco ThousandEyes transaction tests for monitoring?

Answer: A


NEW QUESTION # 19
A network administrator observes a recurring pattern in their Cisco SD-WAN: during peak business hours, users at a specific branch office experience poor voice call quality, characterized by choppy audio and delays. The administrator suspects that network congestion is contributing to this issue and wants to leverage ThousandEyes WAN Insights to improve the situation proactively. Which capability of WAN Insights is most relevant to this scenario?

Answer: C

Explanation:
According to the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, ThousandEyes WAN Insights is a predictive analytics solution designed to transform network management from a reactive to a proactive model. In the scenario provided, the voice quality issues are recurring and peak-hour dependent, indicating a need for optimization rather than just standard real-time alerting.
The most relevant capability for this scenario is analyzing historical SD-WAN performance data to generate path recommendations (Option B). WAN Insights integrates with Cisco Catalyst SD- WAN Manager (vManage) and vAnalytics to ingest massive volumes of telemetry. It uses advanced statistical models to analyze the performance of all active circuits (MPLS, Internet, etc.) over time. If the system identifies that a different available path consistently delivers a higher Quality of Experience (QoE) or better adherence to the voice SLA during those peak windows, it generates a recommendation to adjust the Application-Aware Routing (AAR) policy.


NEW QUESTION # 20
Refer to the exhibit.

Which setting should be enabled for this network Agent to Server test to avoid test traffic being detected by firewalls as malicious?

Answer: B

Explanation:
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) architecture, a critical challenge in active synthetic monitoring is ensuring that test probes accurately reflect user traffic without being dropped by intermediate security appliances. Standard network tests often utilize separate connections for measuring performance metrics (latency/loss) and for path discovery (hop-by-hop visualization). This behavior can be flagged by stateful firewalls or Intrusion Prevention Systems (IPS) as suspicious or malicious scanning activity.
To mitigate this, the engineer should enable Path Trace Mode: In Session (Option A). When this mode is active, ThousandEyes performs path discovery using the exact same TCP session established for the performance measurement. By embedding path discovery probes within an active, established session, the traffic appears to firewalls as part of a legitimate, ongoing communication stream rather than an independent series of probes with varying TTL values that might trigger " anti-spoofing " or " scanning " alerts.
Reviewing the alternative options:
* Protocol: TCP (Option B): While using TCP is generally more firewall-friendly than ICMP, the exhibit shows TCP is already selected. The issue is not the protocol itself, but how the path discovery probes are handled relative to the session.
* Port: 5000 (Option C): Changing the port to a non-standard value like 5000 often makes traffic more likely to be scrutinized or blocked by default firewall policies compared to standard web ports like 80.
* Probing Mode: Force SYN (Option D): Forcing SYN packets is a technique used to bypass certain types of load balancers but does not address the fundamental issue of path discovery probes being seen as a separate, malicious scan by stateful inspection engines.
Therefore, enabling In Session path trace mode is the most effective way to ensure consistent visibility through security-hardened environments.


NEW QUESTION # 21
Refer to the exhibit.

Which two configurations allow the Cisco ThousandEyes Enterprise Agent to use the IPv6 path to perform the DNS query? (Choose two.)

Answer: B,C
