An organization is implementing URL blocking using Cisco Umbrella. The users are able to go to some sites but other sites are not accessible due to an error.
Why is the error occurring?
The issue is occurring because client computers do not have the Cisco Umbrella Root CA certificate installed. When using Cisco Umbrella's intelligent proxy and SSL decryption, it is necessary to install the Umbrella Root CA certificate on client devices. Without this certificate, the browsers on these devices will treat the traffic as being intercepted by a 'man in the middle' and will block access to the sites, resulting in errors.
Should be B. https://support.umbrella.com/hc/en-us/articles/115004564126-SSL-Decryption-in-the-Intelligent-Proxy Requirements and Implementation Although only SSL sites on our 'grey' list will be proxied, it's required that the root certificate be installed on the computers that are using SSL Decryption for the Intelligent Proxy in their policy. Without the root certificate, when your users go to that service, they will receive errors in the browser and the site will not be accessible. The browser, correctly, will believe the traffic is being intercepted (and proxied!) by a 'man in the middle', which is our service in this case. The traffic won't be decrypted and inspected; instead, the entire website won't be available.
Answer is B
Well it's a good thing I paid examtopics to see all the wrong answers on the rest of the questions. This is a missing certificate problem, but the missing certificate is a CA certificate. SSL certificates issued by internal CAs would prove the user's host machine's identity to the website, which is clearly not how web browsing works.
Client computers do not have the Cisco Umbrella Root CA certificate installed.
Answer is B: B. Client computers do not have the Cisco Umbrella Root CA certificate installed.
Should be B

Anwer is B
Answer should be B
The answer is absolutely B, you will find it on the first paragraph in the link I included. https://support.opendns.com/hc/en-us/articles/227987007-Block-Page-Errors-Installing-the-Cisco-Umbrella-Root-CA
https://docs.umbrella.com/deployment-umbrella/docs/rebrand-cisco-certificate-import-information then https://docs.umbrella.com/deployment-umbrella/docs/install-cisco-umbrella-root-certificate all No advice for pushing the Root CA Umbrella into an internal CA. Only via Windows GPO. Cisco wants you to answer B.
you can deploy certificate from internal CA server on cisco umbrella and users pc , so why answer A is wrong ?
Definitely B, was doing it myself https://docs.umbrella.com/deployment-umbrella/docs/install-cisco-umbrella-root-certificate
root certificate be installed on the computers that are using ssl Decryption for the intelligent proxy in their policy https://docs.umbrella.com/deployment-umbrella/docs/manage-intelligent-proxy
