Referring to the topology shown in the exhibit, which two configuration tasks will allow Host A to telnet to the public IP address associated with Server B? (Choose two.)
A. Configure transparent mode to bypass the NAT processing of Server B's public IP address.
B. Configure a stateless filter redirecting local traffic destined to Server B's public IP address.
C. Configure a destination NAT rule that matches local traffic destined to Server B's public IP address.
D. Configure a source NAT rule that matches local traffic destined to Server B's public IP address.
Answer: C,D
Explanation:
In this scenario wehave a host be accessible on the Internet by one address, but have it be translated to another address when it initiates connections out to the Internet.So we need to combine Source and destination NAT.

In the network shown in the exhibit, you want to forward traffic from the employees to ISP1 and ISP2. You want to forward all Web traffic to ISP1 and all other traffic to ISP2. While troubleshooting, you change your filter to forward all traffic to ISP1. However, no traffic is sent to ISP1.
What is causing this behavior?
A. The filter is applied to the wrong interface.
B. The filter should use the next-hop action instead of the routing-instance action.
C. The filter term does not have a required from statement.
D. The filter term does not have the accept statement.
