Which security feature should the architect configure to meet these requirements?

Scenario: A Citrix Architect has set up NetScaler MPX devices in high availability mode with version 12.0.53.13 nc. These are placed behind a Cisco ASA 5505 Firewall. The Cisco ASA Firewall is configured to block traffic using access control lists. The network address translation (NAT) is also performed on the firewall.

The following requirements were captured by the architect during the discussion held as part of the NetScaler security implementation project with the customer’s security team:

The NetScaler MPX device:

✑ should monitor the rate of traffic either on a specific virtual entity or on the device. It should be able to mitigate the attacks from a hostile client sending a flood of requests. The NetScaler device should be able to stop the HTTP, TCP, and DNS based requests.

✑ needs to protect backend servers from overloading.

✑ needs to queue all the incoming requests on the virtual server level instead of the service level.

✑ should provide protection against well-known Windows exploits, virus-infected personal computers, centrally managed automated botnets, compromised webservers, known spammers/hackers, and phishing proxies.

✑ should provide flexibility to enforce the decided level of security check inspections for the requests originating from a specific geolocation database.

✑ should block the traffic based on a pre-determined header length, URL length, and cookie length. The device should ensure that characters such as a single straight quote (“); backslash (); and semicolon (;) are either blocked, transformed, or dropped while being sent to the backend server.

Which security feature should the architect configure to meet these requirements?
A . Global Server Load balancing with Dynamic RTT
B . Global Server Load Balancing with DNS views
C . Geolocation-based blocking using Application Firewall
D . geolocation-based blocking using Responder policies
E . Global Server Load Balancing with Mac Based Forwarding
