This 350-701 practice question tests your understanding of security concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A network team is configuring Cisco FTD for a new branch office. They want to allow outbound web traffic but block all inbound traffic except for a specific public server. Which policy type should be used to allow the return traffic for outbound connections?
A stateless ACL
Why wrong: Stateless ACLs require symmetrical rules for inbound and outbound traffic.
A stateful access rule
Stateful inspection tracks connections and allows return traffic automatically.
A NAT rule
Why wrong: NAT rules translate addresses, not control traffic flow.
SSL decryption
Why wrong: SSL decryption inspects encrypted traffic but does not control return traffic.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A stateful access rule
Cisco FTD uses a stateful firewall engine that tracks the state of outbound connections. When a stateful access rule permits outbound web traffic, the firewall automatically creates a dynamic pinhole for the return traffic, eliminating the need for explicit inbound rules. This is the correct policy type because it maintains session state and allows only related return packets, aligning with the requirement to block all other inbound traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Cisco often tests the misconception that a stateless ACL can handle return traffic for outbound connections, but candidates forget that stateless firewalls require explicit inbound permit rules for return packets, whereas stateful firewalls automatically manage this via connection state tracking.
Detailed technical explanation
Stateful inspection in FTD relies on the Firepower Threat Defense engine, which maintains a connection table tracking 5-tuple information (source IP, destination IP, source port, destination port, protocol). For TCP, the firewall monitors the SYN, SYN-ACK, ACK handshake to establish state, and for UDP, it uses timeouts and heuristic tracking. In a real-world scenario, if the outbound rule permits HTTP (TCP/80) and HTTPS (TCP/443), the state table dynamically allows return packets with the correct source/destination reversal, while unsolicited inbound packets are dropped by the default implicit deny.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
