How much does the operating system cost and does the college have funding? Is the technical support staff at the college able to support the operating systems being considered? Do the operating systems being considered have the ability to support the ports available on the faculty computers? What types of applications do the faculty use and are they compatible with the operating systems being considered?

19 Which two statements should be included in a pre-installation checklist when upgrading an operating system? (Choose two.) Verify that the hardware resources have multiple partitions. Verify that the hardware resources meet or exceed the published minimum requirements. Complete a full backup of all important files and data. Overwrite any data currently contained on the drive to remove all contents. Verify that the hardware resources are certified to work with the existing operating system prior to upgrading.

20 Which two statements are true about drive partitions? (Choose two.) Partitions are necessary in multi-boot installations. A hard drive can be divided into an operating system partition and a data partition. User data is never overwritten when a drive is partitioned. A disk partition is a defined section of an operating system. Each partition requires a different file system type.

21 Which method of interacting with an operating system involves typing commands at a command prompt? CLI GUI redirector kernel translator

CCNA 1 CHAPTER 3

1 Which term is used to describe the process of placing one message format into another format so that the message can be delivered across the appropriate medium? flow control encapsulation encoding multicasting access method

2 Refer to the graphic. What does the router do after it determines that a data packet from Network 1 should be forwarded to Network 2? It sends the data packet as it was received. It reassembles the frame with different MAC addresses than the original frame. It reassembles the data packet with different IP addresses than the original data packet. It reassembles both the packet and the frame with different destination IP and MAC addresses.

3 Refer to the graphic. Five PCs are connected through a hub. If host H1 wants to reply to a message from host H2, which statement is true? H1 sends a unicast message to H2, but the hub forwards it to all devices. H1 sends a unicast message to H2, and the hub forwards it directly to H2. H1 sends a broadcast message to H2, and the hub forwards it to all devices. H1 sends a multicast message to H2, and the hub forwards it directly to H2.

4 An Integrated Services Router (ISR) can perform the functions of which three network devices? (Choose three.) NIC switch router e-mail server wireless access point print server

5 What is the function of the FCS field in an Ethernet frame? detects transmission errors provides timing for transmission contains the start of frame delimiter indicates which protocol will receive the frame

6 What is the purpose of logical addresses in an IP network? They identify a specific NIC on a host device. They are used to determine which host device accepts the frame. They provide vendor-specific information about the host. They are used to determine the network that the host is located on. They are used by switches to make forwarding decisions.

7 A switch receives a frame with a destination MAC address that is currently not in the MAC table. What action does the switch perform? It drops the frame. It sends out an ARP request looking for the MAC address. It floods the frame out of all active ports, except the origination port. It returns the frame to the sender.

8 Which table does a router use to make decisions on where a data packet is to be sent? ARP table routing table network table forwarding table

9 If a router receives a packet that it does not know how to forward, what type of route must be configured on the router to prevent the router from dropping it? dynamic route default route destination route default destination

10 Which address does an NIC use when deciding whether to accept a frame? source IP address source MAC address destination IP address destination MAC address source Ethernet address

11 Which device accepts a message on one port and always forwards the message to all other ports? modem switch router hub

12 Which type of address is used in an Ethernet frame header? logical addresses only IP addresses only MAC addresses only broadcast addresses only

13 Which two statements concerning networking standards are true? (Choose two.) adds complexity to networks encourages vendors to create proprietary protocols provides consistent interconnections across networks ensures that communications work best in a single-vendor environment simplifies new product development

14 What does the 100 mean when referencing the 100BASE-T Ethernet standard? type of cable used type of data transmission speed of transmission type of connector required maximum length of cable allowed

15 Yvonne is talking to her friend on the phone. What type of message is this? broadcast simulcast multicast unicast

16 What is a reason for disabling simple file sharing? It enables the user to map a remote resource with a local drive. It enables the user to share all files with all users and groups. It enables the user to share printers. It enables the user to set more specific security access levels.

17 What is a benefit of having a router within the distribution layer? prevents collisions on a local network keeps broadcasts contained within a local network controls which hosts have access to the network controls host-to-host traffic within a single local network

18 Which two items are included in a network logical map? (Choose two.) naming scheme IP addressing scheme length of cable runs physical location of networking devices specific layout of interconnections between networking devices and hosts

19 What device is typically used as the default gateway for a computer? a server hosted by the ISP the router interface closest to the computer a server managed by a central IT department the switch interface that connects to the computer

20 Which two networking devices are used to connect hosts to the access layer? (Choose two.) router hub switch server computer

21 If the default gateway is configured incorrectly on the host, what is the impact on communications? The host is unable to communicate on the local network. The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks. The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network. There is no impact on communications.

22 Host A needs to learn the MAC address of Host B, which is on the same LAN segment. A message has been sent to all the hosts on the segment asking for the MAC address of Host B. Host B responds with its MAC address and all other hosts disregard the request. What protocol was used in this scenerio? ARP DHCP DNS WINS
