Chapter 10 Concept Question 1-6 1) If an ACL is not configured on an interface, what happens to all routable traffic entering or exiting that interface? Why does this happen? Traffic entering the interface is accepted for processing, and traffic exiting the interface is forwarded. By default, all traffic is permitted on an operational interface that has no access control. 2) A packet is evaluated against the statements in an ACLs. It matches none of the statements. What happens to the packet

File Transfer Protocol File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host or to another host over a TCP-based network, such as the Internet. FTP is built on a client-server architecture and uses separate control and data connections between the client and the server. FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to

After typing the command ipconfig/renew both the IP address and default gateway entries went back to what they were before. 5.3.2 The IP address returned as local host is 192.168.0.112 and the ping message is sent by default times. 5.3.3 The average time it took for the ping response to come back from the default gateway was 2ms. On average

In 1973 the TCP/IP came to be and consisted of dozens of different protocols. Of these key protocols, two are usually considered the most important. The Internet Protocol (IP) is the primary OSI network layer (layer three) protocol that provides addressing, datagram routing and other functions in an internetwork. EX. 3.2 Review 1. The composition

Capture For this investigation, we have decided to use NetWitness Investigator to examine the packets captured from the computers in question. NetWitness Investigator is a software used to examine packets and list login information, transferred data, and IP addresses used, among others. For the purpose of this investigation, we are primarily concerned with the FTP (File Transfer Protocol) sessions and the file names they contained. We can use this information to identify the persons responsible for the
