   A developer is working on a project with a large number of files (over 10,000) that change frequently.

The developer wants to improve performance while maintaining the ability to edit files on the host and have changes reflected in the VM. Which approach should be taken?

   • ASwitch the synced folder type to NFS.
   • BDisable synced folders entirely and use `vagrant rsync` manually.
   • CUse the File provisioner to copy all files into the VM.
   • DIncrease the VM's memory and CPU allocation.

   A developer is setting up a new Vagrant environment for a PHP application. The team wants to use the same base box across all developers, but the box is not yet available on their local machines. The developer writes a Vagrantfile that specifies the box name and version, then runs `vagrant up`. What must happen for the VM to start successfully?

   • AVagrant automatically downloads the box from Atlas (HashiCorp's box repository) if it is not already present locally.
   • BThe developer must first run `vagrant box add` with the exact box name and version, otherwise `vagrant up` fails.
   • CThe box must be manually downloaded and placed in the project directory before `vagrant up` can use it.
   • DThe developer must set `config.vm.box_url` to the Atlas URL for the box to be fetched.
