1. A network administrator is evaluating RIP versus EIGRP for a new network. The network will be sensitive to congestion and must respond quickly to topology changes. What are two good reasons to choose EIGRP instead of RIP in this case? (Choose two.)   EIGRP only updates affected neighbors.   EIGRP updates are partial. 2. Which event will cause a triggered update?   a route is installed in the routing table 3. Refer to the exhibit. If all routers are using RIP, how many rounds of updates will occur before all routers know all networks?   3 4. Refer to the exhibit. The routers in this network are running RIP. Router A has not received an update from Router B in over three minutes. How will Router A respond?   The Invalid timer will mark the route as unusable if an update has not been received in 180 seconds. 5. The graphic shows a network that is configured to use RIP routing protocol. Router2 detects that the link to Router1 has gone down. It then advertises the network for this link

In the previous section we reviewed several aspects of the Transport Layer. We learned a great deal of information; covering sockets, ports, TCP, UDP, segments, and datagrams. Now we will take a look at the fourth and final layer of the TCP/IP stack: the Application Layer. What Does The Application Layer Do? A lot of newcomers to TCP/IP wonder why an Application Layer is needed, since the Transport Layer handles a lot of interfacing between the network and applications. While this is true, the Application Layer focuses more on network services, APIs, utilities, and operating system environments. If you know the TCP/IP stack and OSI model well enough, you’ll know that there are three OSI model layers that correspond to the TCP/IP Application Layer. By breaking the TCP/IP Application Layer into three separate layers, we can better understand what responsibilities the Application Layer actually has. The OSI Equivalent of the TCP/IP Application Layer 1. Application Layer - The sev

Security is a part of every good technical administrator’s game plan. Luckily the good folks at Cisco have made the task of securitizing a Cisco router fairly straightforward in design- with support given for up to five types of passwords. Taking advantage of these passwords is vital to a network’s internal security, and should be implemented where permitted. Enable Password – The Most Basic Of Security Features The two most basic of passwords a Cisco router can provide support for is the enable password and enable secret commands. Depending on the IOS version, administrators will likely only need to setup the enable secret command. For Cisco routers running IOS versions before version 10.3, enable password is going to be used. It is the outdated version of the two, and we’ll see why it isn’t used in average applications after we enable it. You can enable this basic password following the commands seen below. Router> enable Router# config terminal Enter configuration co

If 90% of all problems in a network are on the Physical Layer, then it isn’t any surprise that cable testing has become quite important in the industry. And although it may sound simple to test a pair of cables for faults, actually troubleshooting wire maps, crosstalk, propagation delay, or insertion loss can be more than headache-worthy. And thus, understanding how to troubleshoot these problems saves time, yet also supplies good information to prevent common mistakes in the future. How to Avoid Crosstalk You’ll come to find that the most common mistakes are usually the simplest to avoid. For instance, crosstalk is very commonly created when connectors are not installed properly at both ends of the cable. Crosstalk is the effect we get when electromagnetic energy from one cable leaves an imprint on adjacent cables. (You’ll often see this referred to as “noise.”)This usually isn’t a problem, however, since we twist wires inside Ethernet cable to cancel out this effect. So how, t

The characteristics of RIPv2 follow: - Distance-vector protocol. - Use UDP port 520. - Makes Automatic summarization on network Class boundary. - Classless protocol (supports VLSMs). - Have the power to shut the Auto-summarization And make a configured manual Summarization. - Supports VLSMs. - Metric is router hop count. - Maximum hop count is 15; infinite (unreachable) routes have a metric of 16. - Periodic route updates sent every 30 seconds to multicast address 224.0.0.9. - 25 routes per RIP message (24 if authentication is used). - Invalid route marked after 180 sec. - Flush timer is 280 sec. - Hold-down timer 180 sec. - Supports authentication. - Implements split horizon with poison reverse. - Implements triggered updates. - Subnet mask included in route entry. - Administrative distance for RIPv2 is 120. - Used in small, flat networks or at the edge of larger networks. RIPv2 Convergence The steps for RIPv2 convergence are as follows: 1- When the local router sees a connected route
