45 Which statement is true about the operations of the IPv4 protocol? IPv4 includes additional fields in the IP header, which are required for reliable delivery of the packet. IPv4 operates independently of the media that carry the data at lower layers of the protocol stack. IPv4 provides error control and tracking for the data delivery, and retransmits the packet if it is corrupted IPv4 is a connection-oriented protocol that requires some control data to be exchanged to establish the connection before data transmission. What three statements are true about network layer addressing? (Choose three.) Network layer addressing uses a hierarchy. It uses addresses that are 48 bits in length. It is used by Ethernet switches to make forwarding decisions. It does not support broadcasts. It uses a method by which the network portion of an address can be identified. Network layer addressing identifies each host distinctly.

IP address: 172.16.31.37 Subnet mask: 255.255.255.224 Default gateway: 172.16.31.35
What happens when a node on an Ethernet network is creating a frame and it does not have the destination MAC address? The node drops the frame. The node sends out a Layer 3 broadcast message. The node sends a message directly to the router for the address. The node sends out an ARP request with the destination IP address.
Refer to the exhibit. A router, the table of which is shown, receives a packet that is destined for 192.168.9.4. How will the router treat the packet? It will drop the packet. It will forward the packet via FastEthernet 0/1 . It will forward the packet to the next hop address. Page 54 of 61
It will forward the packet to 172.16.2.0
Refer to the exhibit. A network administrator remotely accesses the CLI of RouterB from PC1 using Telnet. Which statement is true about this connection? The data is automatically encrypted. A Telnet server process is running on PC1. The connection is made through a VTY session on the router. A GET request was sent to RouterB to retrieve data during this session.
Which option shows how a router will route packets to a remote network?

Which combination of network id and subnet mask correctly identifies all IP addresses from 172.16.128.0 through 172.16.159.255? 172.16.128.0 255.255.255.224 172.16.128.0 255.255.0.0 172.16.128.0 255.255.192.0 172.16.128.0 255.255.224.0 Page 56 of 61
How can ARP be used to help document the network? It can list each hop on the way to a destination host. It can show the average latency of hosts on the network. It can provide a list of physical addresses on the network. It can indicate which hosts are not responding to network traffic. Which prompt represents the appropriate mode used for the copy running-config startupconfig command ? Switch-6J> Switch-6J# Switch-6J(config)# Switch-6J(config-if)# Switch-6J(config-line)# Which application belongs to the category of the client/server model? using Telnet to access a router exchanging information via instant messaging printing a document to a locally connected printer scanning a document with a directly connected scanner What information can be gathered by using the command netstat? the default gateway the routing protocol active TCP connections the locally configured subnet mask

Refer to the exhibit. When computer A sends a frame to computer D, what computers receive the frame? only computer D only computer A and computer D only computer B, computer C, and computer D all computersWhich two types of media can provide bandwidth up to 1 Gb/s? (Choose two.) 10 BASE-T 100 BASE-T 100 BASE-FX 1000 BASE-TX 1000 BASE-SX

Refer to the exhibit. RouterB is configured properly. The Ethernet interface Fa0/0 of RouterA is configured with the use of the commands that are shown. However, a ping from the Fa0/0 interface of RouterA to the Fa0/0 interface of RouterB is unsuccessful. What action should be taken on RouterA to solve this problem? Use the description command on the FastEthernet interface Fa0/0. Configure the clock rate of the FastEthernet interface Fa0/0. Use the no shutdown command on the FastEthernet interface Fa0/0. Reboot the router. 44
What happens when a host station receives a frame that contains its own MAC address in the destination fie The Layer 2 information is removed and the frame is pushed up to Layer 3. The host station will copy the information to its buffers and send it back out. The frame originated from the host and will be ignored. The Layer 3 information is added to the frame.
Refer to the exhibit. Host A sends data to host B. Which destination MAC and IP addresses will be encapsulated in the frames when they leave host A?Page 59 of 61
172.16.5.3 2b-53-72-00-1a-2b 172.16.5.3 00-1c-00-5b-3c-2a 192.168.3.1 2b-53-72-00-1a-2b 192.168.3.1 00-1c-00-5b-3c-2a What two processes are specified by the transport layer? (Choose two.) signaling routing encryption segmentation windowingIf the first octet of an IP address begins with binary 101, what class is the address? Class A Class B Class C Class D
Refer to the exhibit. A user on PC1 wants to access a web server on the Internet. An ARP request has been initiated from PC1. Which MAC address will be encapsulated as a destination address in the header of the Ethernet frame when the web request packet is sent out? the MAC address of Fa0/10 interface on SW1Page 60 of 61
the MAC address of Fa0/0 interface on R1 the MAC address of Fa0/1 interface on R2 the MAC address of the web serverWhich statement is true about the CSMA/CD access method that is used in Ethernet? When a device hears a carrier signal and transmits, a collision cannot occur. A jamming signal causes only devices that caused the collision to execute a backoff algorithm. All network devices must listen before transmitting. Devices involved in a collision get priority to transmit after the backoff period.
