A company uses Cisco ASA access lists to filter network traffic to internal servers. They want to allow RDP access (port 3389) only from the company's public IP range. Which type of access list should be created?
Trap 1: Outbound access list allowing traffic from any source to port 3389…
Outbound rules control outbound traffic, not inbound RDP.
Trap 2: Cisco ASA NAT rule [wrong]
Load balancer rules distribute traffic, not filter by source IP.
Trap 3: Inbound access list with destination set to the company's IP range…
Destination should be the VM, source is the company IP range.
