On-Line Users: Ethernet broadcasts Answer: Half-duplex Ethernet--typically 10BaseT--is only about 30 to 40 percent efficient as Cisco sees it, because a large 10BaseT network will usually only give you 3- to 4Mbps--at most. The network administrator needs to design a classful addressing scheme to accommodate the three subnets, with 30, 40, and 50 hosts, as shown.
Option B C. Option C D. Option D E. Option E Answer: B Explanation: The Source and Destination IP address is not going to change. Those two are not going to change. For the MAC address it is going to change each time it goes from one hope to another.
What protocol will the workstation now use to determine the destination MAC address to be placed into frames directed toward the server? HTTP B. DNS C. DHCP D. RARP E. ARP Answer: E Explanation: The RARP protocol is used to translate hardware interface addresses to protocol addresses. When the booting computer sends the broadcast ARP request, it places its own hardware address in both the sending and receiving fields in the encapsulated ARP data packet. TFTP B. FTP D.
C Explanation: TCP is an example of a connection-oriented protocol. It requires a logical connection to be established between the two processes before data is exchanged.
The connection must be maintained during the entire time that communication is taking place, then released afterwards. With orderly release, any data remaining in the buffer is sent before the connection is terminated.
The release is accomplished in a three-way handshake between client and server processes. The connection-oriented protocols in the OSI protocol suite, on the other hand, do not support orderly release. Applications perform any handshake necessary for ensuring orderly release. Examples of services that use connection-oriented transport services are telnet, rlogin, and ftp. If the hubs in the graphic were replaced by switches, what would be virtually eliminated? Ethernet collisions D.
Ethernet broadcasts Answer: Modern wired networks use a network switch to eliminate collisions. By connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain in the case of half duplex links or the possibility of collisions is eliminated entirely in the case of full duplex links.
Host A is sending a packet to Host B for the first time. The Ethernet header includes the source host MAC address and a destination address of all Fs representing a broadcast frame. ARP Request Reference: What kind of cable should be used to make each connection that is identified by the numbers shown? When connecting a PC to a switch, a standard Ethernet straight through cable should be used.
This same cable should also be used for switch to router connections. Generally speaking, crossover cables are only needed when connecting two like devices PC-PC, switch-switch, router-router, etc.
CDP is a device discovery protocol that runs over Layer 2 the data link layer on all Ciscomanufactured devices routers, bridges, access servers, and switches and allows network management applications to discover Cisco devices that are neighbors of already known devices. AC Explanation: Layer 2 switches offer a number of benefits to hubs, such as the use of VLANs and each switch port is in its own separate collision domain, thus eliminating collisions on the segment.
The primary function of an access-layer is to provide network access to the end user. The hardware and software attributes of the access layer that support high availability include security services for additional security against unauthorized access to the network through the use of tools such as Host B sends a frame to Host C. Switch is a layer 2 device and doesn't use network layer for packet forwarding.
The IP address may be used only for administrative purposes such as Telnet access or for network management purposes. There are no collisions in full-duplex mode. A dedicated switch port is required for each full-duplex node.
Ethernet hub ports are preconfigured for full-duplex mode. In a full-duplex environment, the host network card must check for the availability of the network media before transmitting. The host network card and the switch port must be capable of operating in full-duplex mode. ABE Explanation: Half-duplex Ethernet is defined in the original If a hub is attached to a switch, it must operate in half-duplex mode because the end stations must be able to detect collisions.
Half-duplex Ethernet--typically 10BaseT--is only about 30 to 40 percent efficient as Cisco sees it, because a large 10BaseT network will usually only give you 3- to 4Mbps--at most.
Fullduplex Ethernet uses two pairs of wires, instead of one wire pair like half duplex. Also, full duplex uses a point-to-point connection between the transmitter of the transmitting device and the receiver of the receiving device, which means that with full-duplex data transfer, you get a faster data transfer compared to half duplex. And because the transmitted data is sent on a different set of wires than the received data, no collisions occur. The reason you don't need to worry about collisions is because now Full-duplex Ethernet is like a freeway with multiple lanes instead of the single-lane road provided by half duplex.
Full-duplex Ethernet is supposed to offer percent efficiency in both directions; this means you can get 20Mbps with a 10Mbps Ethernet running full duplex, or Mbps for FastEthernet. Converting to binary format it comes to Which two addresses can be assigned to hosts within the same subnet?
CD Explanation: The internetwork is using subnets of the address The routing protocol in use is RIP version 1.
Which address could be assigned to the FastEthernet interface on RouterA? Subnet mask Free VCE and PDF Exam Dumps from PassLeader convert bit-length prefix to quad-dotted decimal representation, then from it find the number of bits used for subnetting you can find previously calculated number of subnets by separating subnets each having value of last bit used for subnet masking Find that your IP address is in which subnet, that subnet's first address is network address and last address is broadcast address.
Based on above steps the answer is option C. Use a DHCP server that is located at the headquarters. Use a DHCP server that is located at the branch office.
Assign the addresses by using the local CDP protocol. Assign the addresses statically on each node. Its best to use static addressing scheme where the number of systems is manageable rather than use dynamic protocol as it is easy to operate and manage. The enterprise has decided to use the network address The network administrator needs to design a classful addressing scheme to accommodate the three subnets, with 30, 40, and 50 hosts, as shown.
What subnet mask would accommodate this network? Subnet mask A i. The subnet address is The lowest host address in the subnet is The last valid host address in the subnet is The network is not subnetted. The mask The block size in the third octet is 2 - So this makes the subnets in 0, 2, 4, 6, etc. The host The next subnet is 4. The valid host addresses are 2. With the there are 8 networks with increments of 32 One of these is 32 33 62 63 where 63 is broadcast so 62 is last valid host out of given choices.
What command will allow the administrator to check the changes that have been made prior to saving the new configuration? This command followed by the appropriate parameter will show the running config hence the admin will be able to see what changes have been made, and then they can be saved. CDP is a Cisco proprietary protocol. CDP is a datalink layer protocol.
CDP is a network layer protocol. CDP can discover directly connected neighboring Cisco devices. CDP can discover Cisco devices that are not directly connected. BCE Explanation: CDP Cisco Discovery Protocol is a proprietary protocol designed by Cisco to help administrators collect information about both locally attached and remote devices. Both these commands will show the current status of the interfaces, either in show or debug mode both will display the information.
If CDP is enabled on all devices and interfaces, which devices will appear in the output of a show cdp neighbors command issued from R2? A Cisco device enabled with CDP sends out periodic interface updates to a multicast address in order to make itself known to neighbors. Since it is a layer two protocol, these packets are not routed. So the devices detected would be immediate connected neighbors.
The two routers have had their startup configurations cleared and have been restarted. At a minimum, what must the administrator do to enable CDP to exchange information between R1 and R2?
Configure the router with the cdp enable command.
If the shut down commands are not entered, then CDP can exchange information between the two routers, else it would fail. The network administrator is testing connectivity from the branch router to the newly installed application server.
What is the most likely reason for the first ping having a success rate of only 60 percent? The network is likely to be congested, with the result that packets are being intermittently dropped. The branch router had to resolve the application server MAC address.
A routing table lookup delayed forwarding on the first two ping packets. Without following these two processes namely switching the packet to appropriate interface and telling the packet where to go by providing it with a destination IP address, the purpose of the same would not be solved.
BC Explanation: This is the basic function of the router to receive incoming packets and then forward them to their required destination. This is done by reading layer 3 headers of inbound packets and update the info to layer 2 for further hopping.
