1. What is a characteristic of a SOHO network?
- It consists of multiple LANs with backbone infrastructure connections.
- It is a small network that connects a few computers to each other and to the internet.
- It is a collection of interconnected private and public networks.
- It is a large network, such as those used by corporations and schools, with hundreds or thousands of interconnected hosts.
- throughput
- latency
- goodput
- bandwidth
Explanation: Latency is a term used to indicate delay when getting a packet from one point to another. Network connections with small amounts of delay are called low-latency networks, whereas network connections with long delays are called high-latency networks. High latency creates bottlenecks in any network communications.3. What type of network is defined by two computers that can both send and receive requests for resources?
- enterprise
- client/server
- peer-to-peer
- campus
- forms the interface between the human network and the underlying communication network
- determines the path and directs data along the way to its final destination
- runs applications that support collaboration for business
- functions as the primary source of information for end devices
5. Which type of cable connection would be used in Packet Tracer to connect a FastEthernet port on a PC to a switch port?
- console
- straight-through
- crossover
- fiber
Explanation: A FastEthernet straight-through cable is used to connect the FastEthernet0 port on a PC to a switch port.
6. Which type of network cable is commonly used in backbone networks and telephone companies?
- fiber-optic cable
- coaxial cable
- twisted-pair cable
- shielded twisted-pair cable
- It identifies the physical location of a data center.
- It identifies a location in memory from which a program runs.
- It identifies a return address for replying to email messages.
- It identifies the source and destination of data packets.
8. A network administrator would like to determine the path a packet takes to reach the destination 192.168.1.1. What is the best command to determine the network path?
- ping 127.0.0.1
- tracert 192.168.1.1
- ping 192.168.1.1
- ipconfig 192.168.1.1
- It can only use the T568A standard at both ends of the cable.
- It can be used to connect two network hosts.
- It is susceptible to interferences from EMI and RFI.
- It is Cisco proprietary.
- host IP address
- subnet mask
- default gateway
- DNS server
Explanation: The types of IP configuration on a host device include these:IP address – identifies the host on the network.Subnet mask – identifies the network on which the host is connected.Default gateway – identifies the networking device that the host uses to access the Internet or another remote network.DNS server – identifies the server that is used to translate a domain name into an IP address.
11. A traveling sales representative uses a cell phone to interact with the home office and customers, track samples, make sales calls, log mileage, and upload/download data while at a hotel. Which internet connectivity method would be a preferred method to use on the mobile device due to the low cost? Explanation: Mobile devices typically use either the cellular network or a Wi-Fi network to connect to the internet. The Wi-Fi connection is preferred because it uses less battery power and is free in many places.12. Which type of technology is used to provide digital data transmissions over cell phone networks? Explanation: 3G, 4G, and 4G-LTE are technologies that are used to provide enhanced cell phone networks that are capable of fast data transmission.13. Which wireless technology is used on smart phones to transmit data to another device within only very close proximity?- Bluetooth
- NFC
- Wi-Fi
- 3G/4G
14. Refer to the exhibit. A student is working on a Packet Tracer lab that includes a home wireless router to be used for both wired and wireless devices. The router and laptop have been placed within the logical workspace. The student adds a laptop device and wants to replace the wired network card with a wireless network card. What is the first step the student should do to install the wireless card?
- Drag the wired network card into the list on the left side.
- Select the WPC300N option from the left and drag that card to the side of the laptop.
- Power off the laptop by clicking on the power button.
- Select the Config tab and then the wireless network card checkbox.
Explanation: Any time you are removing or installing devices into a PC or laptop within Packet Tracer, turn the power off. For the Packet Tracer laptop, use the Physical tab and click on the power button to the immediate right of the power cord.
15.Refer to the exhibit. Which menu item would be used to bring up a web browser?
- Physical
- Config
- Desktop
- Programming
- Attributes
Explanation: The Desktop menu item is used to access common applications and tools used to configure a device such as the IP address, command prompt, web browser, as well as other apps.
16. Refer to the exhibit. A user is creating a wired and wireless network using Packet Tracer. The user has added a home wireless router, a PC, and a laptop. The user configures the home wireless router. Which icon represents the tool that can be used on the laptop to view the SSID and connect to the wireless router?
- PC Wireless
- Web Browser
- IP Configuration
- Command Prompt
Explanation: The PC Wireless icon represents the tool that can be used to view and connect to a specific wireless SSID that has been configured on a wireless router.
