Question 1 Your boss is learning a CCNA training course‚ refer to the exhibit. The access list has been configured on the S0/0 interface of router RTB in the outbound direction. Which two packets‚ if routed to the interface‚ will be denied? (Choose two) access-list 101 deny tcp 192.168.15.32 0.0.0.15 any eq telnet access-list 101 permit ip any any A. source ip address: 192.168.15.5; destination port: 21 not telnet port B. source ip address: 192.168.15.37 destination port: 21 not telnet port

Router and Switches II In Routers and Switches we learned several things such as: what is a Router‚ why we need Routers‚ what is the importance of a Router. We also learned what VLSM is and how to do it and use it. Throughout CCNA we learned how to configure a Router; the different types of Routing protocols and most importantly what‚ when and how to use those protocols in the field. Finally I will discuss Switches in how they are use to set up a LAN. Throughout this paper these topic will be
