Network+ Certification Exam Questions

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.

Answer explanation

The correct answer defines a network as a group of computers and devices, including printers, connected by transmission media, which accurately captures the essence of networking beyond just hardware or wiring.

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.

Answer explanation

The correct choice states that logical network topology refers to how data is transmitted, while physical topology describes the actual layout of devices and cables. This accurately defines the two concepts.

Connie is configuring the network for a new restaurant. 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.

Answer explanation

Peer-to-peer networks allow computers to share files without needing an expensive server, making it cost-effective for Connie's restaurant. Additionally, they are easy to configure, requiring minimal technical expertise.

Irene enjoys working with a client-server architecture. What are some of the benefits of working in a client-server environment? Choose all that apply.

• Easier to manage and maintain than peer-to-peer networks.

• Provides centralized control and security.

• More cost-effective than peer-to-peer networks.

• Offers better scalability and performance for large networks.

Answer explanation

In a client-server environment, centralized control enhances security and management, while scalability and performance are improved for larger networks, making it more efficient than peer-to-peer setups.

Which of the following are advantages of a client-server architecture in network management? Choose all that apply.

• 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.

Answer explanation

Client-server architecture centralizes user account management, allows for remote monitoring and troubleshooting of network issues, and enables centralized access control to shared resources, enhancing efficiency and security.

Why is it better for Emmi to use a client-server architecture over peer-to-peer as her company grows? 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.

• 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.

Answer explanation

Client-server architecture allows users to access resources from any computer, ensures authorized access, and enables administrators to control file permissions, making it more secure and manageable as the company grows.

Protocols are rules used between networked devices for communication.

• True

• False

Answer explanation

True. Protocols are essential rules that govern how networked devices communicate with each other, ensuring data is transmitted accurately and efficiently.

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

• SMTP/POP3

• TCP/IP

• TCP/UDP

Answer explanation

The primary protocols for network communication are TCP/IP. TCP (Transmission Control Protocol) ensures reliable transmission, while IP (Internet Protocol) handles addressing and routing of packets across networks.

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.

Answer explanation

The SMTP server address is essential for sending emails. It facilitates the transmission of messages from Larkyn's email client to the recipient's email server, making it the correct choice.

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?

• The POP3 server is responsible for receiving email on a mail server. When Mace logs on, the POP3

• The POP3 server encrypts email before sending.

• The POP3 server sends email to the recipient.

• The POP3 server stores email temporarily.

Answer explanation

The correct choice states that the POP3 server is responsible for receiving email on a mail server. It allows Mace to log on and retrieve his emails, which confirms its role in handling incoming messages.
