問題文
A company has staff working from home in many countries and wants them to receive the same inspection as staff in the office, without hauling all traffic back to headquarters. Why is a cloud-delivered security service suited to this?
選択肢
- The service replaces the need for any policy, because inspection is applied by the provider using a default rule set that reflects current best practice for all customers of the service, and that rule set is kept current on the customer's behalf.
- Users connect to a nearby location of the service where inspection happens, so policy is enforced close to the user and traffic does not have to traverse the corporate data center first.
- The service installs a hardware appliance in each employee's home, and the appliance holds a copy of the policy, so that inspection is performed locally.
- The service works only for traffic destined to the internet, so private applications must be reached by a separate legacy connection that terminates at headquarters and carries no inspection of its own.
