given printer's IP address is 200.23.16.202 and subnet mask is 255.255.255.224 if we changed with a new subnet mask, which is changed to 255.255.255.128. Find the new network ID and host ID of this printer. You must write both in the standard dot-decimal format without attaching the subnet mask.( show the calculation works)
Using the Nmap tool complete the following tasks and store the outcome into a text file: Scan the open ports of an IP in your network domain (for 192.168.1.102) Scan all the machines in your network and list the available open ports. Create a list of target IP and scan these IP address for open ports and Operating System (OS) details.
Set up the following:There are two switches on VLans: Switch 1)VLan 10, Dept. Admin (Ports: fa0/1-2)VLan 20, Dept. Account (Ports: fa0/21-23)Switch 2)VLan 10, Dept. Admin (Ports: fa0/1-4)VLan 20, Dept. Account (Ports: fa0/18-23)Trunk: (Port: fa0/24) Note : Perform On cisco packet tracer
Which of the following statements is true about NIC (Network Interface Card)? There might be multiple correct answers. When operating in "promiscuous" mode, NIC passes every frame received from the network to the kernel. Each NIC has a MAC address. Each NIC has a hardcoded IP address. NIC checks the destination address for every packet, if the address matches the cards MAC address, it is further copied into a buffer in the kernel. Every NIC on the network will hear all the frames on the wire.
You need to send a document from one computer to another, and you want it to be encrypted. Because the target computer is on a different network, data must pass via one or more routers. Ethernet is the network technology on your network, while Wi-Fi is the network technology on the target network. Should this document transfer function based on what you've learnt about networking? Why do you think that is? In the italicized sections of this description, which levels of the OSI model are involved?
Enable OSPF on the routers in the provided Packet Tracer file as follows: • All three routers use OSPF Process ID 77 and Area 0 • R3 is the DR • R2 is the BDR • R1 is a DROTHER • G0/0/1 on R2 is included in the OSPF area but does not send out OSPF LSAs • When complete, save your Packet Tracer file as FL-OSPF-Multi.pka (i.e., my file would be CM-OSPF-Multi.pka)
Please give a neat and understandable configuration. Thanks. Assume there are 4 voice channels, each occupying a bandwidthof 40 kHz. These 4 voice channels need to be combined into a link with a minimum bandwidth of175 kHz, from 131kHz to 306 kHz. There are guard bands of 5 kHz between the channels to preventinterference. Show the configuration using the frequency domain
