The subsequent time I learn a blog, I hope that it doesnt disappoint me as a lot as this one. I imply, I do know it was my option to read, but I actually thought youd have something fascinating to say. All I hear is a bunch of whining about one thing that you could possibly repair when you werent too busy looking for attention.

For me the correct answer is C – Domain Object because Each time the system performs DNS lookup and waits for the response.

Question is about improving performance. Here performance is asked in terms of additional steps firewall has to undergo.
If domain objects are used, fw has to do dns query, resolve it to an IP address to proceed further.
Manual nat need additional configuration for routes, proxy arps which is time consuming and additional administration burden.
Option B is the right answer
