To increase fault-tolerance, the security administrator for Corp has installed an active/passive firewall cluster where the seco

nd firewall is held in reserve in case of primary firewall failure. Stateful firewall inspection is being used in the firewall implementation. There have been numerous reports of dropped connections with external clients. Which of the following is MOST likely the cause of this problem?
(A) All packets are traversing the passive firewall causing the connections to be dropped.
(B) The heartbeat between the firewalls is not enabled.
(C) Inbound packets are traversing the active firewall and return traffic is being sent through the passive firewall.
(D) All packets are traversing the active firewall causing the connections to be dropped.

How would I get this python code to run correctly? it's not working.​
Elanso [62]

Answer:

See Explanation

Explanation:

This question requires more information because you didn't state what the program is expected to do.

Reading through the program, I can assume that you want to first print all movie titles then prompt the user for a number and then print the move title in that location.

So, the correction is as follows:

Rewrite the first line of the program i.e. movie_titles = ["The grinch......."]

for each_movie_titles in movie_titles:

   print(each_movie_titles)

   

usernum = int(input("Number between 0 and 9 [inclusive]: "))

if usernum<10 and usernum>=0:

   print(movie_titles[usernum])

Line by line explanation

This iterates through the movie_titles list

for each_movie_titles in movie_titles:

This prints each movie title

   print(each_movie_titles)

This prompts the user for a number between 0 and 9    

usernum = int(input("Number between 0 and 9 [inclusive]: "))

This checks for valid range

if usernum<10 and usernum>=0:

If number is valid, this prints the movie title in that location

   print(movie_titles[usernum])
