Network+ IModule 1-Introduction to Networking

Hennessy is studying for the Network+ certification exam. The question asked is, "What is the definition of a network?" How does Hennessy answer?

• A network is a group of devices.

• A network is a group of computers and other devices (such as printers) that are connected by some type of transmission media.

• A network is comprised of the wiring that flows throughout an office space or building.

• A network is computer hardware working together.

David is new at his networking job, and his supervisor quizzes him on the differences between physical and logical network topology. What is the correct answer?

• Physical computer topology refers to how data is transmitted between devices in a network. Logical topology deals with the actual layout of devices and cables.

• Peer-to-peer network topology refers to how data is transmitted between devices in a network. Star topology deals with the actual layout of devices and cables.

• Logical network topology refers to how data is transmitted between devices in a network. Physical topology deals with the actual layout of devices and cables.

• Bus network topology refers to how data is transmitted between devices in a network. Ring topology deals with the actual layout of devices and cables.

Connie is configuring the network for a new restaurant that her company is about to open. She has five desktop computers, four LaserJet printers, and three laptops. She plans on using a peer-to-peer environment. What makes peer-to-peer suitable for Connie's restaurant? Choose all that apply.

• Peer-to-peer is scalable, which means, as the network grows, it is easy to add and change elements.

• The computers on a peer-to-peer network can share folders and files without the need for an expensive server.

• A peer-to-peer network is simple to configure and requires little technical expertise.

• A peer-to-peer network is practical for connecting more than a few computers, since it is not time-consuming to manage network resources.

Irene enjoys working with a client-server architecture. Although it is typically more complex in design and maintenance than its peer-to-peer counterpart, a client-server architecture offers many advantages. What are some of the benefits of working in a client-server environment? Choose all that apply.

Client-server architecture provides several advantages to network management. Which of the following are advantages of a client-server network?

• User accounts and passwords to the network are assigned in one place.

• A central server makes upgrading the network cheaper.

• Problems on the network can be monitored, diagnosed, and often fixed from one location.

• Access to multiple shared resources (such as data files or printers) can be centrally granted to individual users or groups of users.

Emmi is her company's IT manager. Since her company is growing, she wants to switch from a peer-to-peer (P2P) networking architecture to a client-server architecture. The company has grown to 30 users, so why is it better for her to use a client-server architecture over peer-to-peer? Choose all that apply.

• Client-server users can sign on to the network from any computer and get access to the resources that Active Directory allows. This process is managed by AD DS (Active Directory Domain Services). Sharing files on a peer-to-peer network means creating 30 user accounts to share documents and then set up each workstation with the same user accounts.

• In a client-server network, an administrator can ensure only authorized users can access the network.

• In a client-server network, an administrator can control what files a user can open, read, or edit.

• In a client-server network, servers only need as much memory as the clients since their workload is the same.

Protocols are rules used between networked devices for communication.

• True

• False

Jackson is currently preparing for his Network+ certification exam and has encountered a question regarding the communication of computers on a network via common protocols. The question asks about the two primary network protocols that are used for communication. What are those primary protocols?

• SSL/TLS

• SMPT/POP3

• TCP/IP

• TCP/UDP

Larkyn is in the process of setting up his email account and is being prompted for his SMTP server address. What is the SMTP server address for?

• The SMTP server address downloads messages to Larkyn's computer.

• The SMTP server address encrypts email as it sends it.

• The SMTP server address decrypts email as it is received.

• The SMTP server address is used whenever Larkyn sends email.

Mace is in the process of setting up his email account and is being prompted for his POP3 server address. What does the POP3 server do when email is sent to it?
