The correct answer is that this rule performs identity NAT between the two networks without port translation. This is because the NAT configuration maps the source IP address of traffic from the 192.168.1.0/24 network to itself when destined for the 10.0.0.0/24 network, effectively bypassing any address translation while still being processed by the NAT engine. On the Cisco SCOR 350-701 exam, this concept tests your understanding of how FTD identity NAT in the cloud differs from dynamic or static PAT, often appearing as a trick where candidates assume all NAT rules must change the IP address. A common trap is confusing identity NAT with a simple permit statement, but remember that identity NAT still passes through the NAT table, just without altering the source. For a quick memory tip, think “same in, same out” — identity NAT means the original and translated addresses are identical, so no PAT is applied.
350-701 Cloud Security Practice Question
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.

Correct answer & explanation
✓
Performs identity NAT between the two networks without port translation
The NAT rule shown in the exhibit is a static identity NAT (also known as NAT exempt or no-translation NAT) that translates the source IP address of traffic from the 192.168.1.0/24 network to the same IP address when going to the 10.0.0.0/24 network. This is achieved by specifying the source address as both the original and translated address, effectively bypassing any address translation while still being processed by the NAT engine. Since no port translation is configured, it performs identity NAT without PAT, which is why option A is correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Performs identity NAT between the two networks without port translation
Why this is correct
The 'static' keyword with same IP on both sides indicates identity NAT.
Related concept
Read the scenario before looking for a memorised answer.
✗
Translates source IP when traffic goes from outside to inside
Why it's wrong here
The rule is applied on the 'inside' interface; source translation is static for inside to outside traffic.
Translates destination IP from 192.168.1.0 to a public IP
Why it's wrong here
Destination is also static with same IP, so no translation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between identity NAT and dynamic PAT, where candidates mistakenly assume that any NAT rule must involve address translation or PAT, but identity NAT explicitly preserves the original IP without port translation.
Trap categories for this question
Keyword trap
There is no 'pat' keyword; this is identity NAT.
Detailed technical explanation
How to think about this question
Under the hood, Cisco FTD uses the NAT engine to create a static one-to-one mapping where the original and translated addresses are identical, which is often implemented using the 'nat (inside,outside) source static 192.168.1.0 192.168.1.0' command in ASA/FMC. This is commonly used in cloud deployments to avoid breaking IP-based security policies or application protocols that embed IP addresses, such as SIP or FTP, while still allowing the firewall to inspect traffic. A real-world scenario is when two cloud VPCs with overlapping private IP ranges need to communicate without translation, requiring careful route design to avoid asymmetric routing.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
