How many hosts are available for use in a default Class C network?

254 hosts are available. A default Class C network uses 8 bits for host addresses. Thus 28 - 2 = 254.

How many usable IP addresses are provided in a default Class C network address?

254 usable IP addresses are provided. The default subnet mask for a Class C address is 255.255.255.0, or /24. This means that 24 bits are used for the network number and 8 bits are reserved for hosts. 28 = 256. However, because two addresses are reserved for the network address and broadcast address, the amount of usable IP addresses is 254. The formula to calculate usable IP addresses is 2n-2, where n is the number of host bits.

What is a TCP window?

A TCP window determines the number of segments that can be sent before an acknowledgment is required. Note: TCP uses a "sliding window" technique to specify the number of segments that the recipient can accept. Sliding means that the window size is negotiated dynamically during the TCP session.

What is a TCP/IP socket?

A TCP/IP socket is an IP address combined with a TCP or UDP port number. When a host wants to talk to another host, it sends its IP address along with the application (port number) it wants to communicate with. For example, if host 192.168.0.3 wants to talk to host 192.168.0.2 by email, host 192.168.0.3 sends its IP address and destination port number (192.168.0.3:1023) to host 192.168.0.2 with the port number it wants to communicate with (192.168.0.2:25).

What is the difference between a routed and a routing protocol?

A routed protocol is a protocol that provides the information in its network layer to allow a packet to direct traffic and defines the use of fields within a packet. Examples of routed protocols are IPv4 and IPv6. A routing protocol finds routes in an internetwork and maintains route awareness. Routing protocols aid in building and maintaining routing tables that routers will use to determine how routed protocols are routed. Routing Information Protocol v2 (RIPv2), Enhanced IGRP (EIGRP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), and Border Gateway Protocol (BGP) are examples of routing protocols.

How does a router determine the path a packet should take to reach its destination?

You have decided to use ACLs on your router to restrict NTP traffic between networks. Specifically, you want to allow only the server with an IP address of 172.17.8.1 to synchronize time with an NTP time provider with an IP address of 10.0.0.1 on a different network. The NTP protocol runs on UDP port 123. To accomplish this, you create the following ACL on the router connecting the two networks. After applying the ACL to inbound traffic on the interface connected to the 172.17.8.0/24 network, you find that now only 172.17.8.1 can synchronize rime with 10.0.0.1 using the NTP protocol, as intended.

Convert the binary number 01100100 to decimal.

Converting a binary number to decimal is just the reverse of converting a decimal number to binary. When converting from binary, look at the numbers that are considered ON and then find their place value. In the binary number 01100100, the place values 64, 32, and 4 are ON. If you add these place values together, you get the decimal number of 100.

Convert the binary number 0101011011000010 to hexadecimal.

Converting binary to hex is easier than it looks. No matter how large the binary number, always apply the following conversion: Break the binary number into groups of four, starting from the right and moving left. If the binary number is not divisible by four, add 0s to the left end or until you have four digits in every group. Using this equation, 0101011011000010 is broken into the following groups: 0101 0110 1100 0010. After you have created the groups, you can convert the digits to hex. 0101 is 5 in hex, 0110 is 6, 1100 is C, and 0010 is 2, so this binary number looks like the following in hex: 0x56C2.

What is the Internet Protocol (IP)?

IP is a connectionless protocol that provides best-effort delivery and routing of packets. IP has the following characteristics: * Operates at Layer 3 (network) of the Open Systems Interconnection (OSI) reference model and the Internet layer of the TCP/IP (Internet) model. * Is connectionless, providing best-effort delivery of packets. * Uses hierarchical addressing. * Has no built-in data recovery. * Each packet is treated independently; thus each packet can travel a different way to its destination. * Operates independently of the medium that is carrying the data.

What does RFC 1918 define?

RFC 1918 defines reserved (private) networks and addresses that are not routed on the Internet. These addresses are as follows: * 10.0.0.0 to 10.255.255.255 * 172.16.0.0 to 172.31.255.255 * 192.168.0.0 to 192.168.255.255 They are used as internal private addresses within a corporation or home network.

Routing flashcards introduction

Routing is the process of finding a path to a destination and moving data across this path from source to destination. Routers are used to connect different IP networks and are essential devices that help make communication on the Internet. Routers are a major component of the routing process. Without routing, we would not be able to send emails, view our favorite websites, listen to music streams, or watch videos on the Internet. In general, routing is considered a hop-by-hop paradigm. Some exceptions to this exist, such as multicast routing, but the ICND exams do not cover multicasting. Data is moved from router to router until it reaches the destination. A router's main function is path determination and packet forwarding. This section covers the most basic terminology of routing and introduces you to the basics of static routing and configuring a Cisco router with basic IP information. Additionally, CDP is discussed. CDP is a Cisco-proprietary protocol that provides discovery of directly connected Cisco devices.

Provide a brief description of routing.

Routing is the process of finding a path to a destination and moving information across an internetwork from the source to the destination.

How do routing protocols maintain their routing tables with each other?

Routing protocols maintain their routing tables through the transmission of messages. These messages are exchanged between routers at periodic intervals or when a change in the network topology occurs. The information contained in the messages varies from routing protocol to routing protocol.

Understanding TCP-IP flash cards introduction

TCP/IP was created by the Defense Advanced Research Projects Agency (DARPA) to run as the protocol for the ARPANET in 1974. TCP/IP is the most widely used protocol suite in the world today. It is the protocol suite used on the Internet, and most network operating systems (NOS) require TCP/IP to run to communicate with other nodes. TCP/IP is the protocol suite you will encounter the most as a network engineer. You must thoroughly understand TCP/IP and know how it works. As you can tell by its name, TCP/IP is a suite of protocols, with its major protocols being TCP and IP. TCP provides reliable delivery, and IP provides network addressing and routing. Currently, two versions of IP exist: IP version 4 (IPv4) and IP version 6 (IPv6). IPv4 is the most widely used implementation of IP. IPv4 has a 32-bit network address, and IPv6 has a 128-bit network address. Currently, IPv4 addresses are exhausted. As a result, IPv6 is being implementing in the Internet. This section focuses on IPv4 addresses unless otherwise noted. Variable-length subnet masking (VLSM) is a way to divide larger subnets into smaller subnets. VLSM was introduced as a way to save IP addresses from being wasted and can combine networks to summarize routes. Route summarization reduces the size of routing tables and improves convergence time by advertising the entire summary route instead of each individual route. For example, a large company is using the IP range 192.168.1.0 to 192.168.255.255, instead of advertising all 255 networks, the company could summarize one route to all its networks: 192.168.0.0 255.255.0.0 to other routers.

What is the IP protocol number for TCP and UDP?

TCP: 6 UDP: 17 Note: IP protocol numbers are the link in the IP header that points to upper-layer protocols such as TCP and UDP.

Your Internet provider has given you the IP network address of 172.16.0.0/16. You have 18 networks, each with 1200 hosts. You want to assign one IP range per subnet, leaving room for future growth. Assuming that the ip subnet zero command is enabled on all routers, what subnet mask would best achieve your goals?

The subnet mask of 255.255.248.0 would best achieve your goals. If you look at this subnet mask in binary, you can see that you have 5 subnet bits for the network address: 11111111.11111111.11111000.00000000 If you use the subnet equation 25 = 32, 32 available networks will be provided with the subnet mask, which fulfills the requirement for 18 networks and allows adequate growth. This leaves you with 11 bits to be assigned to hosts. This gives you 2046 (211 - 2) addresses, giving you more than enough IP addresses to be assigned to hosts. If you use a subnet mask of 255.255.240.0, you will meet the requirement of 1200 hosts (212 - 2 = 4094 available hosts) but not have enough networks (24 = 16 available networks).

How do you disable CDP on Cisco routers?

Two commands disable CDP on a Cisco router. To disable CDP on the entire device, use the 'no cdp run' global command, as follows: RouterB(config)# no cdp run To disable CDP on an interface only, use the no cdp enable interface command, as follows: RouterB(config)# int f0 RouterB(config-if)# no cdp enable This disables CDP on Fast Ethernet interface 0.

What two common protocols function at the transport layer of the TCP/IP model?

Two protocols that function at the transport layer of the TCP/IP model are as follows: * TCP (Transmission Control Protocol): A connection-oriented, reliable protocol * UDP (User Datagram Protocol): A connectionless and unacknowledged protocol Note: TCP deals with the three-way handshake. Reliability deals with acknowledgments (ACK) and NAKs. TCP uses ACKs and NAKs that are used by other protocols if there is a problem. UDP is characterized as connectionless and does not include a mechanism to guarantee data delivery. UDP uses a best-effort delivery and, on most networks today, can send a packet with minimal to no packet loss without the overhead of TCP.

List two reasons to disable CDP.

Two reasons to disable CDP are as follows: * To save network resources by not exchanging CDP frames. * Security. CDP multicasts information about the device every 60 seconds. Sniffers and other devices can view these multicasts to discover information about your network.

How many usable subnets and usable hosts do you have if you subnet the network address 192.168.1.0 with the subnet mask 255.255.255.240?

You have 16 subnets with 14 hosts in each network. If you subnet 192.168.1.0 with a 28-bit mask (255.255.255.240), you have 16 networks with 14 hosts in each network. If you look at the network address and subnet mask in binary, you can see that in the last octet, you have 4 bits for networks and 4 bits for hosts, as follows: 11000000.10101000.00000000.00000000 11111111.11111111.11111111.11110000 You can apply these bits to the following formula, where x is the amount of borrowed bits: Amount of subnets = 2x Amount of hosts = 2x - 2 Therefore, 24 - 2 = 14 subnets. You can then apply the same equation to determine that the number of hosts is also 14.
