Cisco 300-445 Exam Syllabus Topics:

Topic	Details
Topic 1	Data Collection Implementation: This domain focuses on deploying enterprise and endpoint agents across infrastructure and end-user devices. It covers configuring network, DNS, voice, web, and endpoint tests using ThousandEyes and Meraki Insights, along with implementing synthetic web tests and authentication methods.
Topic 2	Data Analysis: This domain encompasses diagnosing network issues like packet loss, congestion, routing, and jitter, plus end-device problems. It includes analyzing web application performance and identifying security threats such as DDoS attacks, DNS hijacking, and BGP hijacking.
Topic 3	Insights and Alerts: This domain addresses configuring alert rules based on network conditions and end-user experience factors. It covers selecting metrics for stakeholders, validating alerts, and recommending network optimization for capacity planning.
Topic 4	Platforms and Architecture: This domain covers understanding monitoring agent types and placement, active versus passive monitoring, and ThousandEyes WAN Insights. It addresses Cisco platform integrations, metric baselines, and selecting appropriate integration methods and assurance platforms based on business requirements.

Once the user has used our 300-445 learning material for a mock exercise, the product's system automatically remembers and analyzes all the user's actual operations. The user must complete the test within the time specified by the simulation system, and there is a timer on the right side of the screen, as long as the user begins the practice of 300-445 Learning Materials, the timer will run automatic and start counting.

Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q11-Q16):

NEW QUESTION # 11
The alert shown in the exhibit is designed to detect which of the following network security issues?

A. DNS hijacking
B. Route poisoning
C. DNS poisoning
D. BGP hijacking

Answer: D

Explanation:
As shown inExhibit 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 theAlert Conditionssection, which specifies: BGP Origin meets all of: ASN not in 1234.
This specific configuration is the standard method used in ThousandEyes to detectBGP 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 isnotthe 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.
* DNS Issues (Options B and D):These involve the translation of names to IPs and would be detected via DNS-specific tests rather than BGP Origin checks.
* Route Poisoning (Option A):This is a generic term often referring to the manipulation of distance- vector protocol metrics to make a route unreachable; while related to routing, BGP Origin checks are the specific tool for detecting external prefix hijacks.
By monitoring the ASN origin, network engineers can quickly distinguish between a local ISP outage and a global security event where their traffic is being misdirected to an illegitimate network.

NEW QUESTION # 12
Review the exhibits. Based on the evidence, which action is most likely to solve the issue?

A. Modify the authentication credentials
B. Change the HTTP request method to PATCH
C. Modify the firewall rules to allow connections to the target domain
D. Modify the target URL to an available API endpoint

Answer: A

NEW QUESTION # 13
Which deliverables are recommended for app/dev teams based on network assurance data interpretation?

A. Network topology diagrams
B. Performance dashboards
C. Latency analysis reports
D. Application performance reports
E. Security incident reports
F. API usage statistics

Answer: B,D,F

Explanation:
Performance dashboards, application performance reports, and API usage statistics are recommended deliverables for app/dev teams based on network assurance data interpretation, providing insights for optimizing application performance and user experience.

NEW QUESTION # 14
You want to monitor Microsoft Teams using ThousandEyes endpoint agents. Which tests are available for this type of application monitoring?

A. Scheduled and dynamic tests
B. Scheduled tests
C. Dynamic tests
D. Scheduled, dynamic and real user tests

Answer: A

Explanation:
According to the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) best practices for collaboration monitoring, Microsoft Teams (as well as Webex and Zoom) is monitored using a combination of Scheduled and Dynamic tests (Option D).

NEW QUESTION # 15
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?

A. Change to a voice codec suitable for high-latency networks.
B. Add QoS marking of voice traffic with EF.
C. Add more DSP resources for call flow.
D. Shift the VoIP traffic to an alternate server.

Answer: B

Explanation:
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.
