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.
An enterprise is deploying a hybrid email security solution using Cisco Email Security Appliance (ESA) on-premises and Cisco Cloud Email Security (CES). The organization wants to use the cloud for spam filtering while the on-premises ESA handles DLP and encryption for sensitive data. Inbound emails should be processed by the cloud first, then sent to the on-premises ESA. Which architecture correctly implements this requirement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
MX record → Cisco CES → On-premises ESA (internal mail server)
Option D is correct because it places Cisco CES (cloud) first in the email flow to handle spam filtering, then forwards the cleaned messages to the on-premises ESA for DLP and encryption before delivery to the internal mail server. This matches the requirement that inbound emails be processed by the cloud first, then the on-premises ESA, with CES acting as the initial SMTPgateway via MX record.
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.
✗
MX record → On-premises ESA → Internal mail server, with a separate smart host via CES
Why it's wrong here
This does not process inbound email through the cloud.
✗
MX record → Dual MX pointing to both CES and ESA
Why it's wrong here
Dual MX records cause email to arrive at either destination, not sequential processing.
✗
MX record → On-premises ESA → Cisco CES → Internal mail server
Why it's wrong here
This sends mail to on-premises first, bypassing cloud spam filter, then back to cloud, which is inefficient and not desired.
✓
MX record → Cisco CES → On-premises ESA (internal mail server)
Why this is correct
This flow ensures cloud spam filtering first, then DLP/encryption on-premises.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the order of processing in hybrid email architectures, and the trap here is that candidates mistakenly think the on-premises ESA should be the first hop (Option C) or that dual MX records can enforce sequential processing (Option B), when in reality the MX record must point to the cloud service to ensure the correct flow.
Detailed technical explanation
How to think about this question
In a hybrid Cisco email security deployment, the MX record for the domain should point to the cloud service (CES) so that all inbound SMTP connections are terminated there first. CES then forwards the email to the on-premises ESA using a configured gateway or smart host, often over a TLS-encrypted channel. The on-premises ESA can then apply DLP policies and encryption before delivering to the internal mail server, ensuring that sensitive data is only processed after spam has been removed, reducing load and false positives.

Eliminate answers that are true in general but not in this case.
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 practitioner preparing for the 350-701 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

What is the correct answer to this question?
The correct answer is: MX record → Cisco CES → On-premises ESA (internal mail server) — Option D is correct because it places Cisco CES (cloud) first in the email flow to handle spam filtering, then forwards the cleaned messages to the on-premises ESA for DLP and encryption before delivery to the internal mail server. This matches the requirement that inbound emails be processed by the cloud first, then the on-premises ESA, with CES acting as the initial SMTP gateway via MX record.
