Testing and Optimizing Network Design

What is the purpose of stress analysis in network testing?

• To evaluate the availability of network resources under normal conditions

• To test the accuracy of network devices during downtime

• To analyze degradation in service under increased load

• To measure the response tie for applications during peak hours

Why is it important to avoid biases or preconceived notions in test objectives and scripts?

• To reduce the complexity of documenting the testing process

• To prioritize performance analysis over stress or failure testing

• To ensure customer satisfaction with the test results

• To align test results with industry standards and avoid skewed outcomes

Which step is performed first when testing the firewall?

• Stop capturing traffic logs.

• Check the logs for errors.

• Start capturing traffic on both networks.

• Add more computers to test scalability.

What is the primary objective of testing a network design?

• Identify and fix technical issues.

• Meet technical and business goals.

• Test user experience.

• Prepare training manuals.

Which of the following is not a technology used for meeting QoS (Quality of Service) requirements?

• IETF controlled load service

• IETF guaranteed service

• IP differented relay

• IP precedence

What is the benefit of Compressed Real-Time Transport Protocol (cRTP)?

• The priority level helps routers determine how to handle traffic when packets compete for the same network resources.

• Reduces RTP, UDP, and IP headers from 40 bytes to 2-4 bytes

• Implements LFI over low-speed Frame Relay.

• Uses a packet forwading and flooding and prunning strategy

What is the objective of traffic shaping?

• To regulate the flow of data to avoid network bottlenecks.

• To increase the bandwidth of the network automatically.

• To completely block all outbound traffic.

• To prioritize video streaming over other types of traffic at all times.

What is the primary focus of Random Early Detection (RED)?

• Increase network bandwidth automatically during high traffic.

• Dropping all packets when congestion occurs.

• Congestion avoidance rather than congestion management.

• Ensuring all packets are delivered without any loss, regardless of congestion.

How many bits does the IP Differentiated Services Field contain? Select TWO answers.

• Contains 6 bits called Differentiated Services Codepoint (DSCP)

• Contains 2 bits for Explicit Congestion Notification (ECN)

• Contains 6 bits in total, combining DSCP and ECN

• Contains 4 bits for traffic priority indication

All answer below is the type of Cisco Queuing Services EXCEPT

• Priority

• CEF

• Low-latency

• FIFO
