Validation scenario. The Server resource have credential object referenced by its connection. Example:

{
  "resourceRef": "/servers/xxxxxxx",
  "resourceId": "xxxxx",
  "resourceMetadata": {
    "client": "xxx",
    "resourceName": "xxx"
  },
  "etag": "W/\"xxxx\"",
  "instanceId": "xxx",
  "properties": {
    "provisioningState": "Succeeded",
    "connections": [
      {
        "managementAddresses": [
          "server1.contoso.com"
        ],
        "credential": {
          "resourceRef": "/credentials/xxxxx"
        },
        "credentialType": "usernamePassword"
      },
      {
        "managementAddresses": [
          "server1.contoso.com"
        ],
        "credential": {
          "resourceRef": "/credentials/xxxx"
        },
        "credentialType": "X509Certificate"
      }
    ],


{
  "resourceRef": "/credentials/xxxx",
  "resourceId": "xxx",
  "etag": "W/\"xxx\"",
  "instanceId": "xxx",
  "properties": {
    "provisioningState": "Succeeded",
    "type": "X509Certificate",
    "value": "thumbprint",
    "networks": []
  }
}

The X509Certificate credential resource have value pointed to certificate on NC by thumbprint. The cert need to be exist, otherwise will cause connection problem from NC To Hosts.
