D Configure a default gateway on the New York router. It is important to note that the new version of the ICND1 exam includes objectives on password recovery procedures and access lists. Use the IP Host command to add a hostname to the hostname table on the router. After you create the address pool, you specify the network range of addresses to give out with the network command. Static NAT associates a single public address to a single private address, while overloading is the concept that all private addresses translate to the one public address.

To filter by the source IP address of a packet, you should configure standard access lists; to filter by the source and destination IP address, source and destination port, and protocol, on the other hand, use extended access lists.

A Access lists have an implied deny all at the bottom. B You need a subnet mask in the access list command. C You should have used ip access-class instead of ip access-group.

D You should have used a permit instead of deny. What type of access control list allows you to filter by source and destination IP address, source and destination port, and protocol? You would like to ensure that only systems on the A Use the following: access-list 20 permit You have created a standard access list 20 that permits a group of IP addresses.

You would like to use this access list to control who can telnet into the router. What command would you use on the telnet ports? What is the result of the access list in the figure below? A It denies the B It denies the C It denies the D It denies the The ICND1 certification exam expects you to know the basics of configuring a router and also the basics of managing the routing table through static routing.

You can use the ip route command to add a static route to the routing table. You can delete a route from the routing table using the no ip route command. When troubleshooting routing issues, use the show ip route command to view the routing table. The lower the administrative distance, the more trustworthy the knowledge is. To configure the GWLR, you use the ip route command to add a route to the 0.

In order to configure router on a stick, you would create sub-interfaces on the router and enable dot1q as the tagging protocol, along with the VLAN ID, for each sub-interface. You would then configure the switch to use the port with the connection to the router as a trunk port so that it can carry all the VLAN traffic across the port.

Ip route C Packets destined for D The administrative distance to the destination network is You are the administrator for a small network made up of two routers.

What is a quick method you can use to configure routing between all networks? A Build static routes to all unknown routes on each router. D Configure access lists to allow traffic to route between the networks. Your routers are running the RIP routing protocol and you type the following command. What is the outcome of typing this command? Ip route 0. B You have configured RIP to broadcast knowledge of the C You have configured a connected route to forward traffic to D You have configured Gateway of Last Resort so that if there is a packet destined for the You are the administrator for router R1.

According to exhibit, all traffic towards Internet that originates from workstations should forward to Router R1. Explanation: OSPF implements a two-tier hierarchical routing model that uses a core or backbone tier known as area zero 0. Attached to that backbone via area border routers ABRs are a number of secondary tier areas. Deterministic traffic recovery? Scalable and manageable routing hierarchy, reduced routing overhead.

Which of these statements correctly describes the state of the switch once the boot process has been completed? Remote access management of this switch will not be possible without configuration change. More VLANs will need to be created for this switch. Correct Answer: B. This shows that VLAN1 is shut down. Hence remote management of this switch is not possible unless VLAN1 is brought back up.

Based on the exhibited routing table, how will packets from a host within the The router will forward packets from R3 to R2 to R1. The router will forward packets from R3 to R1 to R2. The router will forward packets from R3 to R1. Correct Answer: C. Explanation: From the routing table we learn that network It requires the use of ARP. It can support multiple IPv6 subnets on a single link. It supports up to 2 instances of OSPFv3 over a common link. It routes over links rather than over networks.

Correct Answer: BD. What path will packets take from a host on the The path of the packets will be R3 to R2 to R1. The path of the packets will be R3 to R1 to R2. The path of the packets will be R3 to R1. From the output of the routing table of R3 we learn this network can be reach via It is now ready to find and load an IOS image.

What function does the router perform next? VLANs allow the creation of collision domains by groups other than just physical location. Using VLANs, it is possible to establish networks by different means, such as by function, type of hardware, protocol, among others.

This is a big advantage when compared to conventional LANs wherein collision domains are always tied to physical location. Subnetting is the process of creating smaller networks from a big parent network. Being a part of a network, each subnet is assigned some additional parameters or identifier to indicate its subnet number. A layered network offers many advantages. It allows administrators to make changes in one layer without the need to make changes in the other layers.

Specialization is encouraged, allowing the network industry to make progress faster. A layered model also lets administrators troubleshoot problems more efficiently.

It is not capable of establishing virtual circuits and acknowledgements. Presentation layer supports many standards, which ensures that data is presented correctly. In cases when you need to configure a router remotely, the most convenient is to use the Cisco AutoInstall Procedure.

It can be done in three possible ways: — using Dotted-decimal. For example: For example: 82 1E 10 A1. Internetworks are created when networks are connected using routers. Specifically, the network administrator assigns a logical address to every network that connects to the router. Bandwidth refers to the transmission capacity of a medium. It is a measure of how much volume a transmission channel can handle, and is measured in Kbps. Hold-downs prevent regular update messages from reinstating a downed link by removing that link from update messages.

It uses triggered updates to reset the hold-down timer. Packets are the results of data encapsulation. These are data that has been wrapped under the different protocols of the OSI layers.

Packets are also referred to as datagrams. Segments are sections of a data stream that comes from the upper OSI layers and ready for transmission towards the network. Segments are the logic units at the Transport Layer. Route Poisoning is the process of inserting a table entry of 16 to a route, making it unreachable. This technique is used in order to prevent problems caused by inconsistent updates on a route.

The best way to go about this is to use the equation minus the subnet mask. The hosts that are considered valid are those that can be found between the subnets.

DLCI, or Data Link Connection Identifiers, are normally assigned by a frame relay service provider in order to uniquely identify each virtual circuit that exists on the network.

Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device all of me john legend song free download routers, ccna questions and answers pdf free download are network layer devices. The job of the Data Link layer is to check ccna questions and answers pdf free download are sent to the right device. Another function of this layer is framing. When a switch receives a signal, it creates a frame out of the bits that was extracted from that signal. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port. This is a very efficient means of data transmission, instead of broadcasting it on all ports. Network congestion occurs when too many users are trying to use the same bandwidth. This is especially true in big networks that do ccna questions and answers pdf free download resort to network ccna questions and answers pdf free download. A Window refers ccnna the number of segments that is allowed to be sent from source to destination before an acknowledgement is sent back. Not really. What a bridge actually does is to take the aswers network and pvf it, without changing qestions size of the network. This model uses the Store-and-forward switching method. It stores the entire frame to its andwers and performs a crc check before deciding whether or not to forward that data frame. Frree LLC can also provide error correction. RIP relies on the number of hops in order ccna questions and answers pdf free download determine the best route to a network. On the other hand, IGRP takes consideration many factors before it decides the best route to take, such as bandwidth, reliability, MTU and hop count. BootP is a protocol that is used to boot diskless workstations that are connected to the network. ccna questions and answers pdf free download To get pass download ccna you must answers correct.
