The answer is Data Loss Prevention (DLP). This is a correct capability of Cisco ESA for content filtering because the appliance can inspect outbound email messages for sensitive data patterns, such as credit card numbers or social security numbers, and apply policy-based actions like quarantining or encrypting the message before it leaves the network. On the Cisco SCOR / CCNP Security Core 350-701 exam, this question tests your understanding of the ESA’s full content security stack, which also includes anti-spam, anti-virus, and outbreak filters; a common trap is confusing DLP with simple attachment blocking, but DLP specifically analyzes content context and patterns, not just file types. Remember that DLP is a proactive outbound control, while anti-spam is inbound—think “DLP for data leaving, anti-spam for junk arriving.”
350-701 Content Security Practice Question
This 350-701 practice question tests your understanding of content security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE of the following are capabilities of Cisco Email Security Appliance (ESA) for content filtering? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Anti-spam filtering
B is correct because Cisco ESA includes a sophisticated anti-spam filtering engine that uses multiple techniques such as SenderBase reputation, contextual analysis, and signature-based detection to identify and block unwanted email messages. This is a core content security capability of the ESA, operating at the email gateway to filter inbound and outbound traffic.
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.
✗
Intrusion Prevention System (IPS)
Why it's wrong here
IPS is not a feature of ESA; it is for network security appliances.
✓
Anti-spam filtering
Why this is correct
ESA uses Cisco's and third-party anti-spam engines.

✗
Zero-day malware protection using sandboxing
Why it's wrong here
Zero-day protection is advanced malware protection, but not part of base content filtering; it's an add-on.
✓
Anti-virus scanning
Why this is correct
ESA includes Sophos and McAfee anti-virus engines.

✓
Data Loss Prevention (DLP)
Why this is correct
ESA includes DLP for sensitive data detection.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between native ESA capabilities (like anti-spam, anti-virus, and DLP) and optional integrated features (like sandboxing), leading candidates to mistakenly select sandboxing as a core content filtering function.
Detailed technical explanation
How to think about this question
Cisco ESA's content filtering operates at the SMTP layer, inspecting email headers, body, and attachments using a combination of reputation filters (SenderBase), content filters (based on regex or dictionary rules), and anti-spam engines (such as Brightmail). In a real-world scenario, an organization might configure content filters to block emails containing credit card numbers or proprietary data, leveraging DLP dictionaries and message actions like quarantine or bounce.

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.
