Where and how should the X.509 certificate and Mule applications be used to configure load balancing among the 5 CloudHub workers, and what DNS entries should be configured in order for the retailer to support its numerous business partners?

49 of A popular retailer is designing a public API for its numerous business partners. Each business partner will invoke the API at the URL 58. https://api.acme.com/partnefs/vl. The API implementation is estimated to require deployment to 5 CloudHub workers.

The retailer has obtained a public X.509 certificate for the name apl.acme.com, signed by a reputable CA, to be used as the server certificate.

Where and how should the X.509 certificate and Mule applications be used to configure load balancing among the 5 CloudHub workers, and what DNS entries should be configured in order for the retailer to support its numerous business partners?
A . Add the X.509 certificate to the Mule application’s deployable archive, then configure a CloudHub Dedicated Load Balancer (DLB) for each of the Mule application’s CloudHub workers Create a CNAME for api.acme.com pointing to the DLB’s A record
B . Add the X.509 certificate to the CloudHub Shared Load Balancer (SLB), not to the Mule application Create a CNAME for api.acme.com pointing to the SLB’s A record
C . Add the X.509 certificate to a CloudHub Dedicated Load Balancer (DLB), not to the Mule application
Create a CNAME for api.acme.com pointing to the DLB’s A record
D . Add the x.509 certificate to the Mule application’s deployable archive, then configure the CloudHub Shared Load Balancer (SLB)
for each of the Mule application’s CloudHub workers
Create a CNAME for api.acme.com pointing to the SLB’s A record

Answer: C

Explanation:

* An X.509 certificate is a vital safeguard against malicious network impersonators. Without x.509 server authentication, man-in-the-middle attacks can be initiated by malicious access points, compromised routers, etc.

* X.509 is most used for SSL/TLS connections to ensure that the client (e.g., a web browser) is not fooled by a malicious impersonator pretending to be a known, trustworthy website.

* Coming to the question, we can not use SLB here as SLB does not allow to define vanity domain names. * Hence we need to use DLB and add certificate in there

Hence correct answer is Add the X 509 certificate to the cloudhub Dedicated Load Balancer (DLB), not the Mule application. Create the CNAME for api.acme.com pointing to the DLB’s record
