ohhh so you dint use any variable name paste below code
bundles.UseCdn = true;
           var jqueryBundle= new ScriptBundle("~/bundles/jquery", "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.1.min.js").Include(
                                   "~/Scripts/jquery-{version}.js");
           jqueryBundle.CdnFallbackExpression = "window.jQuery";
          bundles.Add(jqueryBundle);
           BundleTable.EnableOptimizations = true;
for css with Cdn use
bundles.UseCdn = true;
          var StyleBundle = new StyleBundle("~/bundles/Styles","https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css").Include(
                    "~/Content/bootstrap.min.css"


                    );
          StyleBundle .CdnFallbackExpression = "window.Styles";
          bundles.Add(StyleBundle );
          BundleTable.EnableOptimizations = true;

Inside App_Start folder , if there is no class with the name BundleConfig.cs then you can create one, bydefault MVC templates have this class, but if you have selected an Empty MVC template then , you will have to create one like below
public class BundleConfig
   {
       // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
       public static void RegisterBundles(BundleCollection bundles)
       {
           bundles.Add(new ScriptBundle("~/bundles/Scripts").Include(
                       "~/Scripts/Jquery.js",
                       "~/Scripts/bootstrap.min.js",


                       ));
           }

hen register it in global.asax file under Application_Start event like

BundleConfig.RegisterBundles(BundleTable.Bundles);

Where is that bundleConfig.cs file located might be a weird question but I dunno

yes , local means which is in your project script folder.

In your bundleConfig.cs add below lines
bundles.UseCdn = true;
bundles.Add(new ScriptBundle("~/bundles/jquery", "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.1.min.js").Include(
                        "~/Scripts/jquery-{version}.js"));
jqueryBundle.CdnFallbackExpression = "window.jQuery";

BundleTable.EnableOptimizations = true;
if CDN fails to download it will use local Jquery. in your view/Layout you can use like below
@Scripts.Render("~/bundles/jquery")
