All 200-201 Test Inside Cisco Questions

The exhibit shows a UNIX command being used to filter data from an Apache access log file. The use of “cat” to display the content of the log file, “grep” to filter specific IP addresses, and “cut” to organize the output are all indicative of operations performed on a UNIX-based system. Additionally, the structure of the logs (GET requests) aligns with the format typically found in Apache server logs. References := The Cisco Cybersecurity source documents or study guide are not directly referenced here as I need to search for specific content related to this question.

 In TCP/IP networking, the ACK flag is used to acknowledge the receipt of a packet. It’s a way to confirm that the previous packets have been received and that the connection is proceeding as expected. The RST flag, on the other hand, is used to reset the connection. It is sent if a segment arrives which is not intended for the current connection, or if a connection request is to be denied. Essentially, the ACK flag is about maintaining the established connection, while the RST flag is about aborting connections that are not valid or are no longer needed123.

NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network traffic. It collects metadata of the IP traffic flowing across networking devices like routers and switches. On the other hand, Traffic mirroring involves capturing all the data packets that flow through a particular point in the network to analyze or inspect them later. References := Cisco Cybersecurity Operations Fundamentals
