Your Company Outsources CRM to a SaaS Company

Your company outsources CRM to a SaaS company. Users are complaining that the CRM is down. You verify that Internet connectivity is good and that other Internet sites can be accessed. You contact the CRM provider and find that none of their other customers are having issues. You attempt to ping this IP address from your network management system (NMS) , but the ping fails. After reviewing recent changes to your outside router's configuration, you find that several access control lists (ACLs) have been updated. What should you do to verify that the problem is related to the ACL updates?

A) remove the ACLs and retest for connectivity to the CRM
B) contact your ISP to see if they can access the CRM from their site
C) telnet to the outside router and ping the CRM from the router's outside interface
D) re-ping the CRM from your NMS with a special flag so the ping will pass through the ACLs
