You have an Exchange Server 2013 organization that contains a server named Server1.
Server1 has an IP address of 10.1.100.16 and is configured to use a default gateway of 10.1.100.1.
You deploy a hardware load balancer that is configured to use the IP addresses of 192.168.101.31
and 10.1.100.31.
A user named User1 has a client computer that has an IP address of 102.168.101.201. User1 reports
that he cannot view his mailbox by using Outlook Web App.
When you review the IIS logs on Server1, you discover the following information:
#Fields: date time cs-method cs-uri-stem s-port c-ipcs(Referer) sc-status2013-01-09 00:08:55 POST
/owa/ev.owa2 443 192.168.101.201 https://owa.fabrikam.com/owa/ 200
You need to ensure that User1 can access his mailbox successfully from Outlook Web App.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)
A.
Configure the hardware load balancer to use the same certificate as the certificate used on
Server1.
B.
Configure the hardware load balancer to use source NAT (SNAT).
C.
Configure the computer of User1 to ignore response headers.
D.
Modify the default gateway of Server1.
Layer 4 NAT mode (desitnation NAT):
Advantages of Layer 4 NAT mode
* no connection limit
–> * Client Access Servers can see the client IP address
Limitations of Layer 4 NAT mode
–> * the server default gateway must be the load-balancer
* clients and Client Access servers can’t be in the same subnet
* no SSL acceleration, no advanced persistence
* Must use 2 interfaces on the Load-Balancer (or VLAN interface)
