Explanation:

1/user_guide/b_ESA_Admin_Guide_11_1/b_ESA_Admin_Guide_11_1_chapter_0100010.html#t ask_9F07A032042F48C6AEDB69D325CD3C5F


NEW QUESTION # 121
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?

Answer: D

Explanation:
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.


NEW QUESTION # 122
An organization wants ESA to reject SMTP connections from hosts with very poor reputation before message transmission begins. Which feature should be configured first?

Answer: D

Explanation:
HAT evaluates the sender IP during SMTP connection establishment and can use SenderBase Reputation Score (SBRS) values to accept, throttle, or reject connections before message data is transmitted. This conserves system resources and blocks unwanted traffic at the earliest possible stage.


NEW QUESTION # 123
Which two configurations are used on multiple LDAP servers to connect with Cisco ESA? (Choose two.)

Answer: B,E

Explanation:
You can enter multiple host names to configure the LDAP servers for failover or load-balancing. Separate multiple entries with commas.

NEW QUESTION # 124
Which restriction is in place for end users accessing the spam quarantine on Cisco ESA devices?

Answer: B

Explanation:
When end users want to access the spam quarantine on a Cisco ESA, they typically access it directly through a web browser. In order to ensure the security and privacy of the quarantined emails, authentication is required before granting access to the quarantine. This means that users need to provide valid credentials, such as a username and password, to authenticate themselves before accessing the quarantine interface.
