A subnetwork is a network inside a network. The networks are more efficient because of the subs. When a network receives data packets from another network, it will sort and route those packets in a way that doesn’t make them go to their destination in an inefficient way.
A sub network is a logical part of the network. A network is divided into two or more networks. The logical division of an address into two fields is achieved by this.
A mask is used to divide the address. The computer is identified by one part and the network by the other. If you want to understand how an address works, look at it and see how it is organized.
Subnetting is a technique for splitting a network into smaller networks. Subnetting can be used to hide network complexity and reduce network traffic.
The address is made up of 32 bits and can be divided into two parts with the help of a mask. The 32 bits are broken down into 8 bits. The converted octets are separated by a dot.
There are two types of subnetting. Variable length allows for more flexibility.
How many hosts and subs there are.
The formula 2n is used to calculate the number of possible subnets. If three host bits are borrowed, then n is the number. If three host bits are borrowed, there will be eight subnets.
There is a mask on. A subnetwork mask is data used for bitwise operations on a network of addresses that are divided into two or more groups.
A Subnet mask is a 32-bit number that splits the internet address into two parts. Subnet mask is made by setting host and network bits. Host addresses within a network can’t be assigned to hosts.
A 128-bit number is called a subnet mask, and it is used to segment an existing internet address. It is used to determine if a host is on a local or remote network.
The network and host are indicated by the subnet masks. The default subnet mask for class C addresses is 255.255.255.0.
What command should the technician use to solve the problem? The problem is caused by a change in the address of the router. The arp -d command is needed to reestablish the correct cache.
Which command is used to protect passwords? The command service password-encryption is used to protect passwords on a routers.
A secure management connection to a remote device is provided by Secure Shell.
Why would a network administrator use it? Adding a password to a network device is necessary. Is there a way to prevent passwords from being displayed in plain text?
Passwords should include upper and lower case letters, numbers and symbols.
There are 11 items. Which method starts with examining cable connections? In the bottom-up method, a technician would start with the physical components of the network and move up through the OSI model until the problem is identified. There are 12
password-encryption
The command service password-encryption is the first method of security provided by the company. All clear-text passwords are obscured by this command. The feature is enabled from global configuration mode.
5 security best practices.
Limit the ranges that can be used for network infrastructure. Do your users need direct access? Use the network’s network management system. Make sure network device credentials are valid. li>Disable unused network ports /li> Bonus!/li>
You can make your company network less vulnerable to data thefts by following these nine steps.
Use WPA2 Passwords on your business network can be secured with a reliable, secure protocol. /li>li> Allow or restrict. Use a PureVPN. Disable file sharing Always update the router’s software. Use IDS orIPS. WAF can be installed. li>UseSSL certificates./li>
To reach remote networks, hosts must send traffic to a local routers that can route traffic to the correct network. The default gateway is the local one and hosts need to set it up in order to communicate with remote devices.
Which three items are used for security? Choose three. The physical characteristics of the user are compared to the data stored in the device to verify their identity.
A host name has been identified as the source of an attack on a company. What command can a network technician use to determine the host’s internet protocol address?
How to find an internet address. The command line is the easiest way to do that. To open the command prompt, you have to type it in. Click on the command prompt if you want to run as administrator.
The command will cause the computer to ask for a new address from the server. The command will remove the current address, but won’t request a new one. The network is being tested with the ping and tracert commands.
The command dig can be used to query the nameservers for information about host addresses, mail exchanges, and related information. A client is unable to use their computer. Which of the following utilities can be used by a technician? nslookup.
