The correct answer is to configure static NAT for the web server. This is required because the ASA firewall must translate the public destination IP address of incoming HTTPS traffic to the private IP address 10.1.1.100, which is not routable on the internet; static NAT creates a permanent one-to-one mapping that allows the ASA to perform destination address translation for inbound connections. On the Cisco SCOR 350-701 exam, this concept tests your understanding of how NAT interacts with security policies—a common trap is assuming that an access list alone (allowing HTTPS) is sufficient, but without static NAT, the ASA has no way to forward the packet to the internal server. Remember the memory tip: "Static NAT for servers, dynamic NAT for clients"—if an internal resource must be reachable from the outside, it always requires a static translation.

This 350-701 practice question tests your understanding of cloud security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

An ASA firewall is configured as shown. A web server is behind the ASA with IP 10.1.1.100. Which additional configuration is required to allow HTTPS traffic from the internet to the web server?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure static NAT for the web server
Option B is correct because the ASA firewall requires static NAT to translate the public IP address (typically the ASA's outside interface IP or a dedicated public IP) to the private IP address of the web server (10.1.1.100). Without static NAT, the ASA will not perform the necessary destination address translation for inbound HTTPS traffic, and the web server's private IP is not routable on the internet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Add a route to the web server's subnet
Why it's wrong here
A route is already configured for default; no additional route needed.
✓
Configure static NAT for the web server
Why this is correct
Static NAT is necessary to map the public IP to the internal server.

✗
Increase the security level of the inside interface
Why it's wrong here
The inside is already 100, which is higher than outside.
✗
Apply the access-group to the inside interface
Why it's wrong here
The access-list is correctly applied to the outside interface for inbound traffic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume a route or security level adjustment is sufficient, but Cisco specifically tests that NAT is mandatory for translating private addresses to public addresses in ASA firewall configurations.
Detailed technical explanation
How to think about this question
Static NAT on the ASA creates a one-to-one mapping between a public IP (e.g., 203.0.113.10) and the private IP 10.1.1.100, allowing the ASA to rewrite the destination IP of incoming HTTPS packets. Additionally, the ASA must have an access-list applied to the outside interface permitting TCP port 443 to the mapped public IP, and the web server must have its default gateway set to the ASA's inside interface IP for return traffic to be correctly routed.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
