Network+ PM Review Day 1

A growing company has recently moved into a new office space. The company has 50 employees, each with their own workstation. The office also has multiple printers, a centralized server, and requires structured cabling for connectivity. Which type of network would be MOST effective for this setup?

• Small Office/Home Office (SOHO) network
• Wide Area Network (WAN)
• Data Center
• Small and Medium-sized Enterprise (SME) network

A multinational corporation has its main office in New York and branch offices in London, Tokyo, and Sydney. The corporation needs a network that can connect all these offices together, allowing for seamless communication and data transfer. Which type of network would be MOST suitable for this setup?

• Local Area Network (LAN)
• Small Office/Home Office (SOHO) network
• Small and Medium-sized Enterprise (SME) network
• Wide Area Network (WAN)

You own a small business and have decided to set up a network where each computer acts as both a client and a server. This decentralized model should allow for the provisioning, management, and security of services and data that you want distributed around the network. What type of network would BEST meet your requirements?

• Client-Server network
• Peer-to-Peer network
• Virtual Private network
• Enterprise network

Which of the following networking topologies connects each network device to a central forwarding appliance?

• Bus
• Ring
• Star
• Mesh

You've implemented an ad hoc wireless network that doesn't employ a wireless access point. Every wireless network card can communicate directly with any other wireless network card on the network. Which type of physical network topology have you implemented in this network?

• Bus
• Star
• Ring
• Mesh

What is a Protocol Data Unit (PDU)?

• A device that manages data transmission rates
• A measure of data transmission speed
• A chunk of data with protocol-specific headers added at each OSI layer
• A type of encryption used in data transmission

What is the primary purpose of data encapsulation in network protocols?

• To compress data for faster transmission
• To add additional data headers for routing and delivery
• To encrypt data for secure transmission
• To convert data into an analog signal for transmission

An engineer uses a type of network adapter to connect a fiber link to a router. The transceiver fits into an optical interface on a layer 3 Ethernet router. Of the choices, which layer 1 implementation does the engineer utilize?

• Media converter
• Switch
• Bridge
• VoIP endpoint

A communications engineer notices that every time it rains the signal becomes very degraded. Which layer of the OSI model is the engineer most likely troubleshooting?

• Physical
• Data Link
• Transport
• Application

Which of the following statements accurately describes the function of the Session layer (layer 5) in the OSI model?

• The Session layer is responsible for routing packets across different networks.
• The Session layer provides the physical transmission of data over network media.
• The Session layer administers the process of establishing, managing, and terminating a dialog between client and server.
• The Session layer is used for character set conversion, such as between ASCII and Unicode.
