The correct answer is to enable Data Loss Prevention (DLP) with a predefined credit card dictionary on the Cisco ESA. This is the right choice because the DLP engine is specifically designed to inspect outbound email content against pattern-matching dictionaries, and Cisco provides a built-in dictionary that accurately identifies credit card numbers using Luhn algorithm validation and common formatting rules. On the Cisco SCOR / CCNP Security Core 350-701 exam, this concept tests your understanding of content filters versus DLP—a common trap is confusing a simple content filter regex with the more robust DLP feature, which offers predefined, validated dictionaries for regulatory compliance. Remember that DLP dictionaries are not just keyword lists; they include validation logic to reduce false positives. For a quick memory tip: think "DLP = Data + Logic + Patterns," with credit card detection relying on the built-in "Credit Card Numbers" dictionary rather than a custom regex.
350-701 Content Security Practice Question
This 350-701 practice question tests your understanding of content 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 administrator wants to prevent confidential data (e.g., credit card numbers) from being sent via email using Cisco ESA. Which feature should be enabled and configured with the appropriate dictionary?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data Loss Prevention (DLP) with a predefined credit card dictionary
Cisco ESA's Data Loss Prevention (DLP) feature is specifically designed to inspect outbound messages for sensitive data patterns, such as credit card numbers, using predefined dictionaries. By enabling DLP and selecting the appropriate credit card dictionary, the administrator can enforce policies to block or quarantine emails containing confidential information, directly addressing the requirement.
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.
✗
Outbreak Filters with file reputation
Why it's wrong here
Outbreak Filters protect from malware, not data loss.
✗
Anti-Spam with URL reputation
Why it's wrong here
Anti-spam is for spam, not for DLP.
✗
Message Filters with regex pattern matching
Why it's wrong here
While regex can match credit cards, DLP is the prescribed solution and more robust.
✓
Data Loss Prevention (DLP) with a predefined credit card dictionary
Why this is correct
DLP is designed for sensitive data detection using predefined dictionaries.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between content inspection features (DLP) and threat-focused features (Outbreak Filters, Anti-Spam), leading candidates to confuse message filters or outbreak filters with DLP's specialized data classification capabilities.
Detailed technical explanation
How to think about this question
Cisco ESA's DLP engine uses predefined dictionaries (e.g., for credit card numbers, Social Security numbers) that include validation algorithms like Luhn checksum verification to reduce false positives. When a message matches a DLP policy, the ESA can apply actions such as blocking, quarantining, or encrypting the message, and it integrates with Cisco's cloud-based DLP service for updated dictionaries and compliance reporting.

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.
