Cisco Updated 350-701 Exam Questions and Answers by alvey

To enable malware file scanning for the Secure Internet Gateway (SIG), you need to enable Intelligent Proxy, which is a feature of Cisco Umbrella that provides selective proxying of web requests based on the risk level of the domain1. Intelligent Proxy allows SIG to inspect the content of potentially malicious web requests and block or allow them based on the configured policies2. Intelligent Proxy also enables SSL decryption, which is necessary to scan encrypted web traffic for malware3. Enabling IP Layer enforcement, activating the Advanced Malware Protection license, and activating SSL decryption are not required prerequisites to enable malware file scanning for the SIG, although they may provide additional security benefits45. References: 1: Intelligent Proxy - Cisco Umbrella 2: Cisco Umbrella SIG Advantage - Cisco Umbrella 3: [SSL Decryption - Cisco Umbrella] 4: [IP Layer Enforcement - Cisco Umbrella] 5: [Advanced Malware Protection - Cisco Umbrella]

To enable a separated email transfer flow from the Internet and from the LAN, the engineer must use the two-interface deployment mode on the Cisco WSA. This mode allows the WSA to have two separate network interfaces, one for the Internet traffic and one for the LAN traffic. This way, the WSA can apply different policies and settings for each interface, and isolate the email flows from each other. The two-interface mode also provides better performance and security than the single-interface mode, which uses only one network interface for both Internet and LAN traffic12. The other deployment modes, such as multi-context, transparent, or single-interface, do not support a separated email transfer flow from the Internet and from the LAN. References:

Two-interface mode, section “Deployment”.

WSA network configuration, section “Interfaces”.

Other features are dependent on SSL Decryption functionality, which requires the Cisco Umbrella root

certificate. Having the SSL Decryption feature improves:

Custom URL Blocking—Required to block the HTTPS version of a URL.

…

Umbrella’s Block Page and Block Page Bypass features present an SSL certificate to browsers that make

connections to HTTPS sites. This SSL certificate matches the requested site but will be signed by the Cisco Umbrella certificate authority (CA). If the CA is not trusted by your browser, an error page may be displayed.

Typical errors include “The security certificate presented by this website was not issued by a trusted certificate authority” (Internet Explorer), “The site’s security certificate is not trusted!” (Google Chrome) or “This

Connection is Untrusted” (Mozilla Firefox). Although the error page is expected, the message displayed can be confusing and you may wish to prevent it from appearing.

To avoid these error pages, install the Cisco Umbrella root certificate into your browser or the browsers of your users—if you’re a network admin.
