Module 1 / Unit 4 Infrastructure and Design Flashcards
Differentiate between network infrastructure implementations such as LAN, CAN, WLAN, WAN, MAN, PAN, and SAN. □ Understand the design requirements for enterprise and SOHO networks. □ Describe the TCP/IP layer model and identify the main protocols in the TCP/IP suite.
What is a WLAN?
Wireless Local Area Network
What network infrastructure implementation is larger than a LAN but smaller than a WAN?
Metropolitan Area Network (MAN). You could also mention Campus Area Network (CAN).
What is the purpose of a SAN?
A Storage Area Network links together different kinds of storage device (RAID array, hard disks, SSDs, tape drives, and so on) and makes “pools” of storage capacity available to servers to access using blocklevel file read/write commands.
What type of devices are connected in a PAN?
A Personal Area Network (PAN) is used to link devices such as laptops and smartphone and provide connectivity with peripheral devices (printers, input, headsets, and so on) plus wearable technology, such as fitness trackers and smart watches.
What general requirements and limitations should you consider when implementing a basic network?
Device types, environment, equipment, compatibility, wired / wireless, and security
What is the function of a network controller?
Implements the policies defined by Software Defined Networking (SDN) control applications by interfacing with the configuration interfaces of network appliances.
What four layers can be used to conceptualize network design hierarchy?
Access, distribution, core, and data center.
To which layer of the OSI model does the TCP/IP Internet layer correspond?
Network
