100-140 Question 239
Single answerA user reports that they are unable to access a specific web application hosted on the internet. Upon investigation, you discover that the organization's firewall has strict rules in place. What is the most likely reason for this issue, and how could it be resolved?
- A
The firewall is blocking the IP address of the web application, and the rule needs to be modified to allow it.
- B
The firewall is blocking all outbound traffic from the user's computer, and it needs to be configured to allow access.
- C
The firewall is performing deep packet inspection, which is causing delays, but this would not block the web application entirely.
- D
The firewall is misconfigured and is blocking all incoming traffic, which is unrelated to the user's issue.
Show answer and explanation
Correct answer: A
Explanation
Firewalls are used to control and filter network traffic based on predefined security rules. In this scenario, it is likely that the firewall is blocking the web application's IP address, which prevents the user from accessing it. Modifying the firewall rule to allow traffic to the web application's IP address would resolve the issue while maintaining the firewall's overall purpose of protecting the network from unauthorized access.
- A. Correct.
This is the correct answer because firewalls can block specific IP addresses or ranges as part of their filtering rules. Modifying the rule to allow traffic to the web application's IP address would resolve the issue.
- B. Incorrect.
This is incorrect because if the firewall were blocking all outbound traffic, the user would not be able to access any external resources, not just the specific web application.
- C. Incorrect.
This is incorrect because deep packet inspection typically causes delays or performance issues, but it would not block access entirely unless a specific rule is in place.
- D. Incorrect.
This is incorrect because the user's issue is related to accessing an external web application, not incoming traffic. Blocking incoming traffic would not prevent outbound access to the web application.
