質問 # 57
A network administrator notices that there are a high number of queries to the LDAP server. The mail logs show an entry "550 Too many invalid recipients | Connection closed by foreign host." Which feature must be used to address this?
正解：D
解説：
Reference:
https://www.cisco.com/c/en/us/td/docs/security/esa/esa12-0/user_guide/b_ESA_Admin_Guide_12_0/b_ESA_Admin_Guide_12_0_chapter_011010.html DHAP (Directory Harvest Attack Prevention) is a feature that must be used to address this issue. DHAP is a mechanism that allows Cisco ESA to prevent directory harvest attacks, which are attempts by spammers or hackers to obtain valid email addresses from an LDAP server by sending messages with random or guessed recipients and checking for bounce messages.
To enable DHAP on Cisco ESA, the network administrator can follow these steps:
Select Network > Listeners and click Edit Settings for the listener that receives incoming messages.
Under SMTP Authentication Settings, select Enable Directory Harvest Attack Prevention.
Enter a value for Maximum Invalid Recipients per Hour, which is the number of invalid recipients that triggers DHAP.
Enter a value for Block Sender for (hours), which is the duration that Cisco ESA blocks messages from senders who exceed the maximum invalid recipients per hour.
Click Submit.
質問 # 58
An engineer must ensure that email sent from *@cisco.com is not sent to the spam quarantine on a Cisco Secure Email Gateway. What must be configured on the Secure Email Gateway?
正解：C
解説：
To guarantee that email from *@cisco.com bypasses spam quarantine, the engineer must configure a safelist. A safelist explicitly allows messages from trusted senders or domains, preventing them from being flagged or quarantined as spam by the antispam engine.
質問 # 59

質問 # 60
Which process is skipped when an email is received from safedomain.com, which is on the safelist?
正解：C
質問 # 61
Which action do Outbreak Filters take to stop small-scale and nonviral attacks, such as phishing scams and malware distribution sites?
正解：B
解説：
Outbreak Filters can take the action of rewriting URLs to redirect traffic to potentially harm ful websites through a web security proxy. This allows the Cisco Secure Email Gateway to scan the content of the websites and block or warn the user if they are malicious or undesirable. This action can stop small-scale and nonviral attacks, such as phishi ng scams and malware distribution sites, that may not be detected by other filters.
