Question
An administrator notices that the Cisco ESA delivery queue is consistently full. After further investigation, it is determined that the IP addresses currently in use by the Cisco ESA are being rate-limited by some destinations. The administrator creates a new interface with an additional IP address using virtual gateway technology, but the issue is not solved. Which configuration change resolves the issue?
Options
- AUse the CLI command alt-src-host to set the new interface as a possible delivery candidate.
- BUse the CLI command loadbalance auto to enable mail delivery over all interfaces.
- CUse the CLI command deliveryconfig to set the new interface as the primary interface for mail
- DUse the CLI command altsrchost to set the new interface as the source IP address for all mail.

Explanation
Creating a new virtual gateway interface on Cisco ESA allocates a new IP address, but the ESA does not automatically use it for mail delivery. The deliveryconfig CLI command is used to configure global outbound delivery settings, including designating which interface the ESA uses to send mail. Setting the new interface as the primary or active delivery interface via deliveryconfig ensures the ESA actually routes outbound connections through the new IP address, bypassing the rate-limiting affecting the original IPs. altsrchost (D) maps specific sender-to-destination routing rules but would not globally activate the new interface for delivery. loadbalance auto (B) is not a valid Cisco ESA command in this context. alt-src-host (A) is syntactically incorrect.
