New Release 300-720 CCNP Security Questions

spf-status is the section of the filter that must be modified to correct this behavior. spf-status is a condition that determines whether a message matches the content filter rule based on the result of SPF verification, such as pass, fail, neutral, etc.

The content filter in the exhibit has a spf-status condition set to “Pass”, which means that it will match messages that passed SPF verification and apply the action of “Quarantine”. This is the opposite of what the network engineer intended to do.

To correct this behavior, the network engineer can modify the spf-status condition to “Fail”, which means that it will match messages that failed SPF verification and apply the action of “Quarantine”.

The other options are not valid sections of the filter that must be modified to correct this behavior, because they do not affect the spf-status condition.

To allow phishing simul-ations to bypass antispam scanning, the administrator must add two components to the allow list: domains and senders. Domains are the email domains that are used in the phishing simulations, such as example.com or test.com. Senders are the email addresses that are used to send the phishing simulations, such as phish@example.com or test@test.com. By adding these components to the allow list, the administrator can prevent them from being blocked by antispam scanning and allow them to reach the end users for testing purposes. References: [Cisco Secure Email Gateway Administrator Guide - Creating Allow Lists]

ceo@example.com is the data that must be added to the dictionary to accomplish this goal. A content dictionary is a list of values that can be used as a condition in a content filter or a message filter. Forged Email Detection is a feature that allows Cisco ESA to detect and prevent email spoofing attacks, where the sender’s address or domain is forged to appear as someone else, such as the CEO of the organization.

To create a content dictionary for use with Forged Email Detection on Cisco ESA, the administrator can follow these steps:

• Select Mail Policies > Content Dictionaries and click Add Dictionary.
• Enter a name and description for the content dictionary, such as CEO Email.
• Under Dictionary Values, click Add Value.
• Enter the email address of the CEO, such as ceo@example.com.
• Click Submit.

The altsrchost command enables an engineer to deliver a flagged message to a specific virtual gateway address in the most flexible way. This command allows you to specify an alternate source host for messages that match a message filter. You can use this command to route messages to different virtual gateways based on the message content or attributes.
