300-720 Exam Questions & Answers

When CRES (Cisco Registered Envelope Service) is unavailable, Cisco ESA will requeue the message and attempt to resend it later, until the maximum number of retries or the maximum age of the message is reached. The message will not be sent in clear text, dropped, or encrypted by another appliance.

Message Handling Settings:

Repaired Message Handling

Messages are considered repaired if the message was completely scanned and all viruses have been repaired or removed. These messages will be delivered as is.

Encrypted Message Handling

Messages are considered encrypted if the engine is unable to finish the scan due to an encrypted or protected field in the message. Messages that are marked encrypted may also be repaired.

Unscannable Message Handling

Messages are considered unscannable if a scanning timeout value has been reached, or the engine becomes unavailable due to an internal error. Messages that are marked unscannable may also be repaired.

Virus Infected Message Handling

The system may be unable to drop the attachment or completely repair a message. In these cases, you can configure how the system handles messages that could still contain viruses.

According to the [Cisco Secure Email Encryption Service Add-In User Guide], you can create an encryption profile that defines the encryption settings and options for your encrypted messages[2, p. 11]. You can also create an outgoing content filter that applies the encryption profile to the messages that match certain conditions, such as having [SECURE] in the subject header[2, p. 12]. This way, you can allow users to flag the messages that require encryption by adding [SECURE] to the subject line.

The other options are not valid because:

A . Creating an encryption profile with [SECURE] in the Subject setting and enabling encryption on the mail flow policy will not work, as the Subject setting in the encryption profile is used to specify the subject line of the encrypted message envelope, not the original message[2, p. 11].

B . Creating an outgoing content filter with no conditions and with the Encrypt and Deliver Now action configured with [SECURE] in the Subject setting will not work, as this will encrypt all outgoing messages regardless of whether they have [SECURE] in the subject line or not[2, p. 12].

D . Creating a DLP policy manager message action with encryption enabled and applying it to active DLP policies for outgoing mail will not work, as this will encrypt messages based on DLP rules that detect sensitive data in the message content, not based on user flags in the subject line.

Web reputation score is a feature that allows Cisco ESA to evaluate the reputation of URLs in messages based on real-time data from Talos intelligence and apply appropriate actions, such as block, quarantine, or deliver.

To ensure that Cisco ESA evaluates the web reputation score before permitting this email, the administrator should use two criteria to create a content filter or message filter that matches this email and applies an action of ''check web reputation'':

Sender matches test1.com, which means that the sender's domain name is test1.com.

Email body contains a URL, which means that the message body has one or more URLs in it.

The other options are not valid criteria to ensure that Cisco ESA evaluates the web reputation score before permitting this email, because they do not match this email or they are not relevant to web reputation score.

Cisco Talos is a cloud service that provides a reputation verdict for email messages based on the sender domain and other attributes such as IP address, sender behavior, message content, and attachment analysis. Cisco Talos is integrated with Cisco Secure Email Gateway and provides real-time threat intelligence and protection against spam, phishing, malware, and other email-borne threats.

The other options are not valid because:

A . Cisco AppDynamics is a cloud service that provides application performance monitoring and optimization for enterprise applications. It does not provide reputation verdicts for email messages.

B . Cisco Secure Email Threat Defense is a cloud service that provides visibility and remediation capabilities for email threats detected by Cisco Secure Email Gateway. It does not provide reputation verdicts for email messages.

C . Cisco Secure Cloud Analytics is a cloud service that provides network visibility and threat detection for cloud environments. It does not provide reputation verdicts for email messages.
