Question 1 of 179

Which SMTP extension does Cisco ESA support for email security?

ETRN

UTF8SMTP

PIPELINING

STARTTLS

Correct Answer: D

Cisco Email Security Appliance (ESA) supports the STARTTLS extension for email security. STARTTLS upgrades a plain text connection to a secure connection using TLS (Transport Layer Security). This feature provides secure email transmission by preventing eavesdropping and tampering during email transfers.

Question 2 of 179

Which feature utilizes sensor information obtained from Talos intelligence to filter email servers connecting into the Cisco ESA?

SenderBase Reputation Filtering

Connection Reputation Filtering

Talos Reputation Filtering

SpamCop Reputation Filtering

Correct Answer: A

The feature that utilizes sensor information obtained from Talos intelligence to filter email servers connecting into the Cisco ESA is SenderBase Reputation Filtering. SenderBase Reputation Service, which is part of Cisco's security measures, assigns a reputation score to email senders based on data collected globally from the SenderBase Affiliate network. This helps in identifying and filtering potentially harmful email traffic.

Question 3 of 179

When the Spam Quarantine is configured on the Cisco ESA, what validates end-users via LDAP during login to the End-User Quarantine?

Enabling the End-User Safelist/Blocklist feature

Spam Quarantine External Authentication Query

Spam Quarantine End-User Authentication Query

Spam Quarantine Alias Consolidation Query

Correct Answer: C

When the Spam Quarantine is configured on the Cisco ESA, the Spam Quarantine End-User Authentication Query validates end-users via LDAP during login to the End-User Quarantine. This feature specifically handles the authentication process for users accessing their quarantine, ensuring that the correct user has the necessary permissions to view and manage quarantined spam emails.

Question 4 of 179

Which benefit does enabling external spam quarantine on Cisco SMA provide?

ability to back up spam quarantine from multiple Cisco ESAs to one central console

access to the spam quarantine interface on which a user can release, duplicate, or delete

ability to scan messages by using two engines to increase a catch rate

ability to consolidate spam quarantine data from multiple Cisco ESA to one central console

Correct Answer: D

Enabling external spam quarantine on Cisco SMA provides the ability to consolidate spam quarantine data from multiple Cisco ESA to one central console. This centralization allows administrators to manage quarantined messages from multiple devices in a single location, enhancing efficiency and security by reducing the complexity of managing spam across several devices and storing data securely.

Question 5 of 179

When email authentication is configured on Cisco ESA, which two key types should be selected on the signing profile? (Choose two.)

DKIM

Public Keys

Domain Keys

Symmetric Keys

Private Keys

Correct Answer: A, C

When configuring email authentication on a Cisco Email Security Appliance (ESA), the two key types that should be chosen on the signing profile are DKIM and Domain Keys. DKIM (DomainKeys Identified Mail) and Domain Keys are the primary methods used to authenticate the email sending domain. DKIM uses a digital signature to sign the emails, whereas Domain Keys is an older standard that also employs cryptographic techniques to ensure email authenticity. Both methods involve using a pair of cryptographic keys (private and public), but the selection for the signing profile specifically references the type of authentication mechanism, which in this case are DKIM and Domain Keys.
