350-701 Practice Question: A network administrator is troubleshooting an…
A network administrator is troubleshooting an issue where users cannot send emails with attachments larger than 10 MB through the Cisco Email Security Appliance (ESA). The ESA is configured with a mail flow policy that has a maximum message size of 20 MB. What is the most likely cause of the issue?
⚠ Common exam trap
Many candidates confuse the mail flow policy's maximum message size with the attachment size limit, assuming that increasing the message size automatically allows larger attachments, when in fact they are independently configured.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The ESA default maximum attachment size is 10 MB.
The Cisco ESA has a built-in default maximum attachment size of 10 MB, which is separate from the mail flow policy's maximum message size. Even though the mail flow policy allows messages up to 20 MB, the attachment size limit is enforced by the ESA's default configuration, which caps individual attachments at 10 MB. This default can be overridden in the mail flow policy or system settings, but if not explicitly changed, it remains the limiting factor.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The mail flow policy maximum message size is set too low.
Why it's wrong here
The mail flow policy maximum message size is 20 MB, so it is not too low.
- ✗
The HAT (Host Access Table) maximum message size is set to 10 MB.
Why it's wrong here
The HAT maximum message size is 20 MB as given.
- ✗
The outgoing mail policy has a smaller attachment size limit.
Why it's wrong here
Outgoing mail policies do not have a separate attachment size limit.
- ✓
The ESA default maximum attachment size is 10 MB.
Why this is correct
The default maximum attachment size in ESA is 10 MB, which restricts attachments even if the overall message size is larger.
