I have not had too much experience with IPtables and was asked to create this policy in iptables. Any help?

Talking of "hard", that image is hard to read. It's too small and is completely unreadable so we'll all have no idea what you need to do.

Sorry about the first attached quality. I have uploaded it to imgur to avoid file size limits!

If this is some kind of exercise or test, I think you first should try yourself and then ask specific questions.
And I believe CentOS 7 comes with firewalld as default.

There is forwarding in the question and FirewallD (in el7) is not made for it.
Linux kernel has had nf_tables since version 3.13 and even el7 has it (backported).
It would make much more sense to now learn nft rulesets rather than iptables.
