I agree with the above, but in case you're not quite willing to spill your guts for whatever reason, for anyone else who's interested in these topics:

1) Log shipping/Replication/Mirroring/Clustering-uses-steps to implement it
Each of those is a chapter in a book. I recommend starting with google: MSDN SQL <keyword>
2) What will you do if sql server is slow
These are troubleshooting techniques that range a wide span of items. It's meant to get an idea of your experience, vs. what you learned in a book.
3) What will you do if tempdb, transaction log file is full
That's a really good question. What WILL you do? Best way to start that research is get yourself a small partition on a drive (usually your C:\ is smaller), create a database, and fill it with stuff until your Transaction Log is out of room. You'll get some errors. Start researching those errors. It's a common issue.
4) How to take tail backup if db is corrupted-steps
This doesn't make sense directly. Are you remembering the question properly? You want to look into Tail-Log backups, and point in time restores.
5) Can we change the default port/if yes what is the use of doing it?
I'll give you a hint as to why this is important. A massive worm ran rampant through SQL Servers the world over a while back, and default ports were how it found the software, amongst other things. The question, though, is straightforward enough to directly research.
6) Where will you check the error apart from activity monitor in ssms? what will you do if the error log file is missing?
Another experience and system familiarity question. Again, easily researched on the net.
7) How do you check disk space/ How do you resolve if you have any issues?
Again, easily researched if you're talking about automated detection. But c'mon, how do you check it?
8) How do you check/solve blocking issues
Research: deadlock, exclusive locks, Isolation Levels.
9) What are the frequent database issues you face in your present job & how you troublshoot it?
Did you think about what you typed here, or did you just cut and paste something you found somewhere? This is a personal question, with a personal answer.
10)What is the sev3/sev4 issue you have faced till now?
What's a sev3/sev4 issue?
To the OP:
Seriously? This looks like you snagged a series of interview questions off a site somewhere and are trying to cram-prep for an upcoming interview without even taking the time to read the questions. (How to check for disk space available... grumble mutter) I've given hints and clues here for any other newbies who might stumble on this thread so they have some ideas on what to research on their own, but it looks like you're shortcutting before you even get to the interview.
Never stop learning, even if it hurts. Ego bruises are practically mandatory as you learn unless you've never risked enough to make a mistake.
