NEW QUESTION # 112
What limitations should be considered when implementing synthetic web tests for network assurance?
Answer: A,C,E
Explanation:
Limitations of synthetic web tests for network assurance include the lack of real user behavior replication, limited scalability for large networks, and sensitivity to browser and device differences, impacting the accuracy of test results.
NEW QUESTION # 113
Which tool is commonly used for configuring network tests related to TCP/UDP performance?
Answer: B
Explanation:
Thousand Eyes is commonly used for configuring network tests related to TCP/UDP performance, offering comprehensive monitoring and analysis capabilities.
NEW QUESTION # 114
Which integration type allows for seamless data exchange between Cisco technologies and external systems?
Answer: A
Explanation:
API integration enables seamless data exchange between Cisco technologies and external systems, facilitating efficient network management and monitoring.
NEW QUESTION # 115
An architect needs to analyze network path metrics from their internal network, specifically from the access layer to a cloud-hosted web server.1 Which ThousandEyes agent is most appropriate for this task?
Answer: C
Explanation:
In the framework of Designing and Implementing En 8 terprise Network Assurance (300-445 ENNA) , selecting the correct agent type depends heavily on the vantage point required for the specific observation. For this scenario, the architect must collect metrics from the internal network access layer -the point closest to where the users or devices reside within the corporate perimeter-towards a cloud-hosted destination.
The Enterprise Agent (Option B) is the most appropriate choice because it is specifically designed to be deployed on infrastructure owned and managed by the organization. These agents are " inside-out " vantage points that can be installed directly on Cisco Catalyst 9300 or 9400 Series switches at the access layer using Docker containers. By deploying an Enterprise Agent at the access layer, the architect gains visibility into the entire network path, starting from the internal LAN, traversing the edge/WAN, and reaching into the cloud- hosted web server. This allows for the identification of issues such as local congestion, ISP peering problems, or cloud provider latency.
Other options do not meet the criteria:
* Synthetic Agent (Option A): This is a distractor term. All ThousandEyes agents (Cloud, Enterprise, and Endpoint) are synthetic agents because they all perform active synthetic testing.
* Cloud Agent (Option C): These are pre-deployed by Cisco in global ISP data centers and provide an " outside-in " view. 14 While useful for monitoring public-facing availability, they cannot provide visibility into the internal network or the access layer of the organization.
* Endpoint Agent (Option D): While these are installed on end-user machines and provide a " user- centric " view, they are generally not used for infrastructure-level path analysis from the access layer switches themselves.
Thus, the Enterprise Agent is the definitive choice for monitoring from the access layer to the cloud.
NEW QUESTION # 116
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.
Answer: B,E
Explanation:
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.
DNS Trace tests (Options C and E) are less suitable for measuring specific resolution times of a single server; instead, they are used to visualize the entire delegation path from the root servers down to the authoritative servers to identify where a " break " in the chain occurs. Furthermore, an A record query (Option A) only provides the IPv4 address, failing the requirement to monitor IPv6. By selecting DNS Server tests for AAAA and NS records, the administrator ensures they have the precise performance data needed to baseline and troubleshoot the organization ' s DNS health.
