THIS EQUAL TO 17 QUESTIONS

[edit] 2.1 Identify a MAC (Media Access Control) address and its parts.

A 48-bit value used by network adapters to uniquely identify a device (like your PC). It has 6 sets of 12 hexadecimal symbols, separated by colons or dashes.

example: 00:0A:B3:73:7A:32

It is broken into 2 parts

(first 3 pair) represents the device manufacturer and is referred to as the Organizationally Unique Identifier (OUI)(second 3 pair) is the device ID, a value unique to that device Valid hexadecimal symbols are 0-9 followed by A-F (a total of 16 characters).

[edit] 2.2 Identify the seven layers of the OSI (Open Systems Interconnect) model and their functions.

• 7. Application
• 6. Presentation
• 5. Session
• 4. Transport
• 3. Network
• 2. Data Link
• 1. Physical

[edit] 2.3 Identify the OSI (Open Systems Interconnect) layers at which the following network components operate:

• Hubs - Layer 1 (Physical)
• Switches - Layer 2 (Data Link)
• Bridges - Layer 2 (Data Link). Note that some newer switches can also operate at Layer 3 (Network).
• Routers - Layer 3 (Network)
• NICs (Network Interface Cards) - Layer 1 (Physical)
• WAPs (Wireless Access Points) - Layer 2 (Data Link)

[edit] 2.4 Differentiate between the following network protocols in terms of routing, addressing schemes, interoperability and naming conventions:

• IPX / SPX (Internetwork Packet Exchange / Sequence Packet Exchange)
• NetBEUI (Network Basic Input / Output System Extended User Interface)
• AppleTalk / AppleTalk over IP (Internet Protocol)
• TCP / IP (Transmission Control Protocol / Internet Protocol)

[edit] 2.5 Identify the components and structure of IP (Internet Protocol) addresses (IPv4, IPv6) and the required setting for connections across the Internet.

[edit] 2.6 Identify classful IP (Internet Protocol) ranges and their subnet masks (For example: Class A, B and C).

[edit] 2.7 Identify the purpose of subnetting. Default gateways was removed.

[edit] 2.8 Identify the differences between private and public network addressing schemes.

[edit] 2.9 Identify and differentiate between the following IP (Internet Protocol) addressing methods:

• Static Static addresses are configured at the end station or device. They are easy to configure initially but management of static addresses become a burden after the network grows beyond a few devices. Static addresses stay configured through reboots so a static address assigned to a client does not change.

• Dynamic Dynamic addresses are assigned using a DHCP (Dynamic Host Configuration Protocol) server. Dynamic address assignment relieves a great deal of management burden on large networks since most devices expect to be dynamically configured and initiate the process automatically on startup. DHCP addresses potentially change with every reboot of the client computer.

• Reserved To balance the extremes of static addressing and dynamic addressing, reserved addressing is supported on most DHCP servers. In reserved addressing, the client initiates a DHCP request on bootup but the server always assignes the same address to the client computer. This may be necessary in some locations when internet access is controlled.

• Self-assigned (APIPA (Automatic Private Internet Protocol Addressing)) APIPA addressing is preconfigured on the device when it is manufactured. The device typically tries to get an address through DHCP and when that fails, it picks a random address in the 169.254.x.x range. The client pings this address and if no response is recevied, it assumes it. If it receives a response, it picks a new address in the same range and pings it. It repeats this process until a suitable address is found.
