Ports 1 to 1023 4. Identify the port numbers for the following applications a. Telnet 23 b. HTTP 80 c. FTP 20, 21 d. DNS 53 e. DHCP 67, 68 5. Define the purpose of a connection oriented protocol. Give an example. It establishes the network connection, manages the data transfer, and terminates the connection.
You can easily tell if this is the problem by comparing the size of the DHCP address scope to the number of devices on your network that request IP addresses from the DHCP server. But since only some of the workstations have got addresses the problem might be the DHCP server. Start off by doing some ping tests to verify that the DHCP server is able to communicate across the network. If the DHCP server is able to communicate with other computers on the network, then I recommend verifying that the DHCP server has an IP address that is compatible with the scope that the server is configured to assign addresses from. The server itself has to be assigned a static address in the same subnet range, such as 192.168.0.199.
2. The subnet mask of an IP address does which of the following? b. Defines network and host portions of an IP address. It is the portion of the IP address that can be used to produce hosts or user IPs for devices.
C. - Multiple internal host addresses can be translated to a single outside global address. D. - NAT offers an additional security layer between outside and inside host. 32. Which of the following protocols is NOT classified as an interior routing protocol? A. OSPF B. BGP C. EIGRP D. RIP Match the terms with their best corresponding definitions or concepts.
An advantage of the star topology is the simplicity of adding additional nodes. The primary disadvantage of the star topology is that the hub represents a single point of failure. Bus: In local area networks where bus topology is used, each node is connected to a single cable. Each computer or server is connected to the single bus cable. A signal from the source travels in both directions to all machines connected on the bus cable until it finds the intended recipient.
Basically, you would have two switches fed by the server. From there, you would have each station fed by one of the switches as well as any other network device like a printer. You would set security rights from the server software and each user would be able to have different security settings. 2. On a peer-to-peer network, each piece of the network would act like part of the chain would be both the client and the server.
Internet Protocol Security (IPsec) was originally developed for IPv6, but found widespread deployment first in IPv4, for which it was re-engineered. IPsec was a mandatory specification of the base IPv6 protocol suite, but has since been made optional (Wikipedia, 2013). Multicasting is the transmission of a packet to multiple destinations in a single send operation, it is part of
Enterprise Network - connects many types of networks. Link - a ring or loop in a chain. Node - a point at which lines or pathways intersect or branch; a central or connecting point. Internet/the Internet - is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users
The packet filters examine packets to verify source and destination; the circuit level filters ensure valid interactions and application filters inspect, screen, block or redirect if necessary, and modify the data as it is transferred across the network. The hardware firewall coupled with the software firewall would protect the network. There are countless firewall software to choose from. The company can install a server managed antivirus on all the systems. The server can manage the restrictions of the firewall.
This is a company that provides connectivity to the Internet. m. Triple play: This is a reference to the bundling of Internet, TV, and Phone services by a provider. n. Cloud Computing: This is a form of computing using remote resources. Cloud computing allows a user to access a service or application without the local host doing any of the computing. An example of cloud computing would be a free email site such as Yahoo or Gmail.
