What is the Maximum Message Size for Encryption on Cisco ESA?

A.

The Cisco Email Security Appliance (ESA) provides email encryption capabilities to protect sensitive email content from being accessed by unauthorized users. When configuring the ESA for email encryption, administrators can set a maximum message size limit beyond which messages will not be encrypted.

Regarding the maximum message size limit for encryption on the Cisco ESA, the available options are:

A. 20 MB B. 25 MB C. 15 MB D. 30 MB.

The correct answer depends on the specific version of the ESA software and the configuration settings of the appliance.

In general, the maximum message size limit for encryption on the Cisco ESA can be configured by adjusting the "Max Encryption Message Size" setting in the "Outgoing Mail Policies" section of the ESA web interface. This setting limits the size of messages that can be encrypted by the ESA.

In some versions of the ESA software, the default value for this setting is 10 MB, which means that messages larger than 10 MB will not be encrypted by default. However, this value can be changed by the administrator depending on their specific needs.

Therefore, to determine the maximum message size that can be configured for encryption on the Cisco ESA, the administrator needs to log in to the ESA web interface and check the current value of the "Max Encryption Message Size" setting under the "Outgoing Mail Policies" section.

If the setting has not been modified from its default value, then the maximum message size limit for encryption on the Cisco ESA would be 10 MB. However, if the administrator has increased this value to the maximum allowed by the ESA software version, then the answer to the question would depend on which value was selected, either 20 MB, 25 MB, or 30 MB.

In summary, the maximum message size that can be configured for encryption on the Cisco ESA depends on the specific ESA software version and the administrator's configuration settings.
