   A manager needs to monitor a network that carries sensitive customer data. The organization must comply with a regulation that requires monitoring of all access to this data. The manager is considering using NetFlow for monitoring. What is the main limitation of NetFlow for this requirement?

   • ANetFlow is not compatible with modern network devices
   • BNetFlow cannot be used for performance monitoring
   • CNetFlow generates too many alerts
   • DNetFlow does not capture the content of the traffic, so it cannot verify what data was accessed

   A network manager is troubleshooting a performance issue. The monitoring data shows high packet loss on a critical link, but latency is normal. The manager must decide whether to replace the link or investigate further. What is the most appropriate action?

   • AInvestigate further because packet loss with normal latency may indicate a specific issue such as a faulty interface or buffer overflow
   • BReplace the link because packet loss is always a sign of a failing link
   • CIgnore the packet loss because latency is normal
   • DIncrease the link's bandwidth

   A network manager is analyzing monitoring data and sees that a server's average latency has increased from 10 ms to 50 ms over the past month, but bandwidth utilization is stable. The server is critical to a business application. The manager must decide whether to investigate or accept the change. What is the most appropriate action?

   • AInvestigate the latency increase because it may indicate a developing problem
   • BIncrease the server's priority in the network
   • CReboot the server to reset the network stack
   • DAccept the change because bandwidth is stable
