Linux interview questions and Answers



                        Now I am going to start a new post which will be updated on timely basis , helpful for the guys who are preparing for interview in Linux field....


1.What are the main difference from LINUX and WINDOWS ?


  1. Linux is an open source software and Windows is a closed source software.
  2. Because Linux is an open source software so whenever a users faces a threat or problem he report the same on community discussion form and developers starts to finding the solution. While Windows OS takes 2 to 3 month for correction of reported threat and error and after that releases new patches and updates.
  3. Linux OS is most secure than Windows OS.
  4. Linux systems are well known for their ability to run for years without failure
  5. Linux also handles a large number of processes running at once much better than Windows does--that's something, in fact, that tends to degrade Windows' stability quickly.

SAN Interview questions

SAN Interview questions


1. WHAT ARETHE BENEFITS OF FIBRE CHANNEL SANS?
 Fibre Channel SANs are the defacto standard for storage networking in the corporate data center because theyprovide exceptional reliability, scalability, consolidation, and performance.Fibre Channel SANs provide significant advantages over direct-attached storagethrough improved storage utilization, higher data availability, reducedmanagement costs, and highly scalable capacity and performance.
2. WHAT ENVIRONMENT IS MOST SUITABLE FOR FIBRECHANNEL SANS?

Typically, Fibre Channel SANs are most suitable for large data centers runningbusiness-critical data, as well as applications that require high-bandwidthperformance such as medical imaging, streaming media, and large databases.Fibre Channel SAN solutions can easily scale to meet the most demandingperformance and availability requirements.
3. WHAT CUSTOMER PROBLEMS DO FIBRE CHANNEL SANSSOLVE?

The increased performance of Fibre Channel enables a highly effective backupand recovery approach, including LAN-free and server-free backup models. Theresult is a faster, more scalable, and more reliable backup and recoverysolution. By providing flexible connectivity options and resource sharing,Fibre Channel SANs also greatly reduce the number of physical devices anddisparate systems that must be purchased and managed, which can dramaticallylower capital expenditures. Heterogeneous SAN management provides a singlepoint of control for all devices on the SAN, lowering costs and freeingpersonnel to do other tasks.
4. HOW LONG HAS FIBRE CHANNEL BEEN AROUND?

Development started in 1988, ANSI standard approval occurred in 1994, and largedeployments began in 1998. Fibre Channel is a mature, safe, and widely deployedsolution for high-speed (1 GB, 2 GB, 4 GB) communications and is the foundationfor the majority of SAN installations throughout the world.
