Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q88-Q93):

NEW QUESTION # 88
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,C

Explanation:
According to theDesigning 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 ServerandDNS Trace.
To satisfy the specific requirements of monitoringIPv6 recordsandname server resolution times, the engineer must utilize theDNS 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 asAAAA 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 toAAAA(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 forNS (Name Server) records.
By creating a DNS Server test targeting theNS 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 resolutiontimesof 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, anA recordquery (Option A) only provides the IPv4 address, failing the requirement to monitor IPv6. By selectingDNS Servertests forAAAA andNSrecords, the administrator ensures they have the precise performance data needed to baseline and troubleshoot the organization's DNS health.


NEW QUESTION # 89
Analyzing the IT operations dashboard, which agent has a better HTTP Connect Time?

Answer: B

Explanation:
Detailed Explanation:
In the IT Operations Dashboard, performance metrics are displayed per agent to facilitate granular troubleshooting. By reviewing the latest metrics table, the Mexico City Mexico (TelMex) agent displays a Connect time of 0.51 ms, which is significantly lower (and therefore "better") than the corresponding time for the San Jose CA agent. Connect time measures the duration for the TCP three-way handshake; a lower value indicates faster network-layer establishment.


NEW QUESTION # 90
Which Cisco technology provides insights into WAN performance and helps identify network issues affecting application delivery?

Answer: A

Explanation:
Thousand Eyes WAN Insights provides insights into WAN performance and helps identify network issues affecting application delivery by monitoring end-to-end network paths, measuring latency, packet loss, and jitter, and providing real-time analytics and visualizations to troubleshoot performance problems.


NEW QUESTION # 91
Which action must be taken first in the Connect ThousandEyes task when integrating Cisco Meraki dashboard and Cisco ThousandEyes?

Answer: D


NEW QUESTION # 92
Which alert rule configuration is commonly used to monitor TCP protocol behavior?

Answer: D

Explanation:
Connection timeouts are commonly used in alert rule configurations to monitor TCP protocol behavior and detect potential network issues such as connection failures or delays.


NEW QUESTION # 93
