Question 181

-- Exhibit --

Refer to the exhibits.

An LTM device has been configured for load balancing a number of different application servers. Configuration changes need to be made to the LTM device to allow administrative management of the servers in 172.16.10/24, 172.16.20/24, and 172.16.30/24 networks. The servers require outbound access to numerous destinations for operations.

Which solution has the simplest configuration changes while maintaining functionality and basic security?

Remove 172.16.10.0:0/24, 172.16.20.0:0/24, and 172.16.30.0:0/24, and keep 0.0.0.0:0/0.0.0.0 enabled on all VLANs.

Replace 172.16.10.0:0/24, 172.16.20.0:0/24, and 172.16.30.0:0/24, with 172.16.0.0:0/16, and keep 0.0.0.0:0/0.0.0.0.

Enable 172.16.10.0:0/24, 172.16.20.0:0/24, and 172.16.30.0:0/24 on ingress VLAN(s), and enable 0.0.0.0:0/0.0.0.0 on egress VLAN(s).

Enable 172.16.10.0:0/24, 172.16.20.0:0/24, and 172.16.30.0:0/24 on egress VLAN(s), and enable 0.0.0.0:0/0.0.0.0 on ingress VLAN(s).

Question 182

-- Exhibit --

Refer to the exhibits.

A virtual server has been configured for SSL offload on a single-arm network. On average, the virtual server will be handling 100,000 connections, with a peak of 130,000 connections. Between the virtual server and the web servers there is a single reverse proxy to provide site caching. The proxy is configured to perform source IP persistence before contacting the web servers. The site is logging users out immediately after logging them in.

What should the LTM Specialist do to resolve this issue?

Add a source address persistence profile to the virtual server.

Create an iRule to add client IP persistence to a SNAT pool member.

Change the virtual server server-side TCP profile to tcp-lan-optimized.

Configure the virtual server HTTP profile to insert an X-Forwarded-For header.
