Certificate Installation on vBond and vSmart Controllers

Reading the qualifier The task says the engineer must apply certificate installation configuration to the vBond Orchestrator and the vSmart Controller — two separate controller node types, not vManage. So the correct image must be a controller-side snippet that is valid on both vBond and vSmart. Any option that only shows the vManage-only trust subcommands (for example the vmanage-root-ca-trust / vmanage-server-cert style directives) or that configures just one controller fails the "and" in the question.

What "certificate installation" actually contains On the controllers the certificate work happens under the certificates configuration mode: define the trust store by trusting the root CA (and optionally an intermediate chain), then generate the local key pair / CSR or load the issued server certificate, and finally have the controller present that identity during DTLS/TLS and OMP/OMP-control handshakes. A snippet that merely sets the organization name, the device lists, or the system identity does not install a certificate, so those options are eliminated by the noun "certificate installation."

Why the remaining options split The deciding detail is whether the option applies both the root-CA trust and the local key generation/server-cert step in one command block that works on vBond and vSmart. Option A is the only image that shows that full pair on a controller, and community voters converge on A as well — one of them even questions whether the reference to sshd is a real service name or a typo, since SSH/NETCONF must be reachable before DTLS/TLS negotiation succeeds. That aside does not change the verdict: A is the certificate installation configuration for both controllers.

Eliminating the rest B, C and D either show only partial trust configuration, target a single controller, or show non-certificate settings, so each is ruled out by the word "installation" combined with the required coverage of both vBond and vSmart. Correct answer: A.
