DRAG DROP
You are configuring a test network. The test network contains a subnet named LAN1. LAN1 uses the network ID of 10.10.1.0/27. You plan to add a new subnet named LAN2 to the test network. LAN1 and LAN2 will be connected by a router.
You need to identify a valid network ID for LAN2 that meets the following requirements:
• Ensures that hosts on LAN2 can communicate with hosts on LAN1.
• Supports at least 100 IPv4 hosts.
• Uses only private IP addresses.
Which network ID should you use? To answer, drag the appropriate network ID and subnet mask to the correct location in the answer area.
