Suppose in a environment multiple firewall .Here is the below example
A-is a host
B-is 1st firewall in which A is connected
C- is a firewall
D-is a firewall
E - is host connected with D firewall.
A will travel if he wants to connect E
1st it will go B then C,Then D, Then E.
If in firewall D traffic is blocked for A to E and in B and C firewall is allowed for all traffic for A to E.
Now in this scenario if I run packet tracer from A to E in firewall B what information will get is the traffic show allowed or Drop?

Packet tracer simulates a packet through the firewall you are running packet tracer on, not end to end.

Hi,
Thanks for all your response.
I would like to add one more point that is how can I get the entire path from source to destination?
If I run traceroute from source firewall Can I get the all firewall details in between source firewall and destination host?
Thanks

Traceroute will give you all the devices in the path. But ASA drops Traceroute by default and does not count as a hop by default.
The following needs to be done on all the firewalls in the path for you to be able to see them in traceroute. I recommended that you remove the decrement-ttl command once you are finished testing.
policy-map global_policy
class class-default
set connection decrement-ttl
access-list outside-in extendend permit icmp any any time-exceeded
access-list outside-in extended permit icmp any any unreachable
access-group outside-in in interface outside
