What is a benefit of implementing URL filtering on the Cisco ESA?
Answer(s): C
A benefit of implementing URL filtering on the ESA is that it provides URL reputation protection. URL filtering uses SenderBase, a web-based service that collects information about URLs and domains from various sources, to assign a reputation score and a category to each URL. Based on these attributes, you can configure content or message filters to take actions on messages containing malicious or undesirable URLs.

When virtual gateways are configured, which two distinct attributes are allocated to each virtual gateway address? (Choose two.)
Answer(s): A,B
Virtual gateways are a feature that allows Cisco ESA to host multiple email domains on a single physical interface, using different IP addresses and hostnames for each domain. When virtual gateways are configured, two distinct attributes are allocated to each virtual gateway address:Domain, which is the email domain name that is associated with the virtual gateway address, such as mycompany.com or mydomain.com.IP address, which is the IPv4 or IPv6 address that is assigned to the virtual gateway address, such as 199.209.31.X or 2001:db8::X.The other options are not attributes that are allocated to each virtual gateway address on Cisco ESA.
