"Your Apex code contains field level access checks that are redundant now that you've added 'WITH SECURITY_ENFORCED'. Please check your code again."

Code is:-

@RestResource(urlMapping='/secureApexRest')
global with sharing class SecureApexRest {
    @HttpGet
    global static Contact doGet(){
        Id recordId = RestContext.request.params.get('id');
        Contact result;
        if (recordId == null){
            throw new FunctionalException('Id parameter is required');
        }
        if (Schema.SObjectType.Contact.isAccessible()
            && Schema.SObjectType.Contact.fields.Name.isAccessible()
            && Schema.SObjectType.Contact.fields.Secret_Key__c.isAccessible()){
            List<Contact> results = [SELECT id FROM Contact WHERE Id = :recordId WITH SECURITY_ENFORCED];
            if (!results.isEmpty()) {
                result = results[0];
            }
        } else{
            throw new SecurityException('You don\'t have access to all contact fields required to use this API');
        }
        return result;
    }
    public class FunctionalException extends Exception{}
    public class SecurityException extends Exception{}
}

Kindly suggest me what exactly I need to change in the code.
Thanks inadvance.

Hi all , 
I am new to salesforce and aim to be a certified developer , can anyone please give me some suggestions and tips on how to prepare for salesforce platform developer 1 exam.
Thanks

Just failed my Admin 201 test. I'm so angry and frustrated. I took a ton of practice tests and did well on them. The actual test was nothing like the practice test. The actual test was ridiculously vague.  Anyway, does anyone know where I can find practice tests that are actually up-to-date? Any suggestions on how to study that doesn't cost a billion dollars? I'm just super frustrated and angry right now. Thanks for the help.
