- Q3. What is multipathing

Multipathing is a technique used in storage systems to provide redundancy and load balancing by using multiple paths between servers and storage devices.

It allows for load balancing by distributing I/O traffic across multiple paths.
Redundancy is achieved by having multiple paths in case one fails.
Multipathing can be implemented at the hardware or softwar...
- Q4. How many types of topologies in San and explain it one by one
- Ans.
There are three types of topologies in SAN: point-to-point, arbitrated loop, and switched fabric.
Point-to-point topology connects two devices directly.
Arbitrated loop topology connects devices in a loop, where each device has a unique address.
Switched fabric topology connects devices through a central switch, allowing multiple simultaneous connections.
Examples: Fibre Channel (FC) and Internet Small Computer System Inte
- Q5. How many types of backup
- Ans.
There are three types of backup: full, incremental, and differential.
Full backup: backs up all data and takes the longest time and uses the most storage space
Incremental backup: backs up only the changes made since the last backup and is faster and uses less storage space than a full backup
Differential backup: backs up all changes made since the last full backup and is faster than a full backup but uses more storage sp
- Q6. What is replication
- Ans.
Replication is the process of creating and maintaining a copy of data or information in another location.
Replication ensures data availability and disaster recovery.
It can be synchronous or asynchronous.
Examples include database replication, file replication, and virtual machine replication.
- Q7. What is reduplication
- Ans.
Reduplication is the process of eliminating duplicate data in storage systems.
Reduplication reduces storage space requirements and improves backup and recovery times.
It works by identifying and removing identical data blocks and replacing them with pointers to a single copy.
For example, if multiple users have the same file attachment in their emails, reduplication will store only one copy of the attachment and point to...

- Q5. Let's go through CV again, and judged the CV experience and sections, saying "Looks like you have SOME experience in the past". After such sentence I felt anger towards them, not polite at all.
Interview Preparation Tips
For me they looked like proud and arrogant of themselves working in the company that shares famous Japanese name "Hitachi", though it's Hitachi Vantara founded in USA not Japan. They lack a simple politeness and respect to the opposite person which adds a bit nervousness. I cannot perform well even I know the topic enough if someone is looking at my work, and they force me to read loud the code fragment and try to debug it without debugger or compiler, guess what's the error in the code. After 3rd stage, 1-2 weeks later they rejected me without telling why. I knew very well that because of their attitude to me I was nervous and Yes, I did naive mistakes when harrying my answers, however they gave me no help on relaxing me, but making more and more tension, and I wanted to quit interview as soon as possible. Therefore, do not think they have culture from Japan like showing kindness. Very bad attitude towards my CV, though I receive from many recruiters my experience stands out as it has strong Computer Science education and multicultural environment experience.
I'd say for Junior position they ask more than typical Junior developer would be able to demonstrate. Anyone with more knowledge, or actually more preparations for interview questions would never apply to that far town somewhere in South West, Dorset of England and with that low salary barely reaching range of 35-40K.
After 3rd interview which was final, and they should've rejected or given an offer, I really wished won't pass, because I didn't like their attitude towards their company as they judged my CV with some sarcasm, then mentioned Hitachi and their Japanese colleagues with a bit of sarcasm of lacking English knowledge, about Japan as a country with different culture. Felt they are a bit racist or proud of being British, if I may call it.
I'm doubt if they as experienced software engineers would be able to answer deep CPP questions, or modern CPP otherwise why would they stack in that job over decades, and I know they do not receive high salaries.
Prepare for having less pleasant interview that you usually have with professional teams.
