Which monitoring technique provides visibility into application-level performance, such as response time for a specific application?

Application Performance Monitoring (APM)

A network team is troubleshooting slow application performance. They have access to NetFlow, SNMP, and a packet capture tool. Which combination of tools would provide the most comprehensive view of the problem?

Use only SNMP to monitor device CPU and memory.

Use only packet capture to analyze all traffic in real time.

Use NetFlow and SNMP, but skip packet capture because it is too complex.

Use NetFlow to identify traffic patterns, SNMP to check device health, and packet capture to analyze specific flows.

A financial trading firm is designing a new network for its London office. Traders require real-time market data feeds with sub-10ms latency and zero tolerance for jitter during trading hours. The network team must also support routine file transfers and email. Which design approach best meets the stated user experience requirements?

Use a network monitoring tool to measure latency and jitter after deployment, and adjust the design based on observed performance.

Implement a single class of service with FIFO queuing to keep the network design simple and avoid configuration errors.

Increase link bandwidth to 10 Gbps on all switches and routers to ensure that all traffic, including market data, has ample capacity.

Classify and mark market data traffic as high priority, and implement strict priority queuing for that class while using weighted fair queuing for other traffic.

Based on measured performance data showing high latency for a critical application, which optimization is most appropriate?

Implement QoS to prioritize the application's traffic

Increase the MTU on all interfaces

Increase the routing protocol timers

After monitoring shows that a WAN link is consistently congested, which optimization would most directly improve user experience?

Change the routing protocol to OSPF

Disable TCP checksum offloading

Reduce the MTU on the WAN interface
