Answer : The possible solutions to the limitation of IPv4 addressing are:. Which Rfcs Discuss About Cidr? In classful IP addressing, the network ID portion can take only the predefined number of bits 8, 16, or In classless addressing, any number of bits can be assigned to the network ID. Answer : In CIDR IP addressing, the first 'n' bits of an IP address are assigned to identify the network and the remaining bits are used to identify the host, where the value of 'n' may be between 1 to The value of 'n' depends on the number of hosts in the network.
The IP prefix identifies the number of significant bits used to identify a network. For example, Answer : In a Ethernet network, a system broadcasts the data using a Ethernet frame. The destination system is specified in the Ethernet frame using its Ethernet address. All the systems in the network listen for an Ethernet frame with their Ethernet address in it. When a system receives an Ethernet frame with its address in it, it processes the frame and sends it to the higher layers like IP for further processing.
What Is A "collision"? Answer : At any one instance, in an Ethernet network, only one device can transmit. If two devices transmit at the same instance, then the signals from both devices will collide and a "collision" will occur. When a "collision" occurs, the signals will get distorted and the frame will be lost. Collisions are very common in a Ethernet network. The following steps are followed to recover from a collision. What Is "late Collision"?
Answer : An Ethernet device will detect a collision, while it is transmitting, only if the collision reaches it before it completes transmitting the entire frame.
If the collision reaches the transmitter, after it completed sending the entire frame, then the transmitter will not detect the collision, it will assume the collision occurred because of some other frame. This is called "late collision". Late collision will occur, if the length of the Ethernet network segment is greater than the standard allowed length. Answer : Late collision can be avoided, if the maximum length of the Ethernet network segment is restricted, such that if a collision occurs, it will reach the transmitter before the transmitter completed transmitting the entire frame.
In a typical 10 Mbps network, the minimum length of an Ethernet frame is bits 72 bytes and the maximum length of a single Ethernet network segment is 2. Popular Interview Questions.

What Is An Rfc? The routing tables will become large. A separate routing table entry is needed for each network resulting in a large number of routing table entries. This is the latest version of IP. This solves a lot of problems in IPv4. This document doesn't discuss about IPv6. What Is Cidr? CIDR can reduce the number of routing table entries. Step 1: Before an Ethernet device sends a frame on the Ethernet cable, it listens to find if another device is already transmitting a frame Carrier Sense.
Step 2: Once the device finds that other devices are not transmitting any frame, it starts transmitting the frame. If two devices detect that the Ethernet cable is free at the same time, then both will start transmitting the frames Multiple Access. Answer: A forest in MCSA is a group of Window trees usually most being effective to work out a plan for global catalog servers.
Answer: Knowledge Consistency Checker is primarily used as a toll gate to filter any plagiarism topology both within the site operations and on an inter-site level as well. Answer: As the name suggests, Windows Server backup is mainly a recycle bin tool that allows the user to backup or store large quantities of their data to be accessed at a later stage.
This is highly user-friendly which accounts for its popularity amongst all. Raid 10 is Combination stripping and Mirroring. Dynamic Host controlling protocol. Instated of manual assigning the IP address. It will automatically assign the IP address from the server. Like that, Creating multiple scopes Is Multiscope. Restrict user or group level permission, Like Wallpaper, Not accessing Pen drive, control panel seating. Installing minimal level application installation form Server.
Download all updates into Server, From the server push to the client. The main purpose to reduce internet bandwidth and control from the server. The client should have a PXE boot function to established for accessing from the server. The main purpose of the PowerShell is to automate administrative tasks that work both local and remote Windows machines.
Replication is a process in active directory that keeps domain controller syncs with other DC over the network. It is a utility tool in Windows Servers for the administrator for managing server roles like adding or removing server roles.
The directory services are just like a database for storing computers, users, objects, etc. Domain, tree, and forest are a logical structure in Active Directory. Domain: A domain is a collection of computers, users, and objects which share common AD and has trust relationships.
Tree: A tree collection of one or more domains. Forest: The forest is the top of the Active Directory structure. It is consists of multiple trees that share a common global catalog. Active Directory is Microsoft directory services used on Windows servers.
Active Directory is a centralized database for users, computers, networks, printers, files Types of backup in windows server Full backup , Incremental backup , Differential backup. Also, it acts as a back-up server to the primary server by providing fault tolerance and load balancing Stub Zone: It consists of a copy of name server and SOA records which is used for reducing the DNS search orders.
A logical group of network objects for example computers, users, devices, etc which share the same active directory database is known as a domain.
The collection of one or more domains is known as a tree. This may also include a contiguous namespace linked in a transitive trust hierarchy. Forest consists of multiple Domains of trees. The Domain trees in a forest do not form a contiguous namespace however share a common schema and global catalog GC.
