Instead of using the Enterprise Console Ul, how can an administrator import an existing keypair to manage the Controller SSL certificate?

Show Suggested Answer Hide Answer
Suggested Answer: A

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the method to import an existing keypair to manage the Controller SSL certificate without using the Enterprise Console UI is to add the keypair to the keystore.jks using a third-party tool (A). The keystore.jks file is the default keystore for the Controller that contains the private keys and certificates for the secure communication on port 8181. If the administrator already has a custom keypair that is signed by a third-party Certificate Authority (CA) or an internal CA, they can use a third-party tool, such as KeyStore Explorer or OpenSSL, to import the keypair into the keystore.jks file. The administrator should also import the root or intermediate certificates of the CA into the cacerts.jks file, which is the default truststore for the Controller. The administrator should use the keytool utility, which is bundled with the Controller installation, to import the certificates into the cacerts.jks file.The administrator should also update the password for the keystore.jks and cacerts.jks files, and restart the Controller to apply the changes12.

The incorrect options are:

Re-run the Controller installer and specify the new keypair. (B) This is not a valid method because the Controller installer does not allow the administrator to specify a custom keypair for the Controller SSL certificate. The Controller installer only allows the administrator to specify the Controller host name, port, account name, access key, and database settings.The Controller installer does not modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore3.

Upload a new keystore.jks file through the Controller UI. This is not a valid method because the Controller UI does not provide any feature to upload a new keystore.jks file for the Controller SSL certificate. The Controller UI only allows the administrator to view and edit the Controller settings, such as the license, the security, the email, the analytics, and the EUM.The Controller UI does not access or modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore4.

Upload the keypair from within the Controller UI. (D) This is not a valid method because the Controller UI does not provide any feature to upload a custom keypair for the Controller SSL certificate. The Controller UI only allows the administrator to view and edit the Controller settings, such as the license, the security, the email, the analytics, and the EUM.The Controller UI does not access or modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore4.

Ooh, this is a tough one. I can see the merits of each option, but I'm kinda partial to option A. Adding the keypair to the keystore.jks with a third-party tool just feels like the cleanest, most straightforward approach. Plus, who doesn't love a good old-fashioned third-party tool, am I right?

Haha, I love these certification exam questions. They really make you think, don't they? I'm not sure about this one, though. Option B, re-running the installer, seems a bit convoluted to me. I'd probably go with C and upload a new keystore.jks file.

Haha, you got that right, my friend. Third-party tools are the spice of life when it comes to IT certifications. But hey, what do you think about option D? I'm still pretty convinced that's the way to go.

Hmm, you make a good point. Option D does seem like it could be a viable solution. I mean, who doesn't love a good old-fashioned UI-based keypair upload, am I right? Though I gotta admit, the third-party tool approach still has a certain je ne sais quoi to it.
