A technician is setting up a small office network. The ISP provides a cable modem with a single Ethernet port. The office has 15 computers that all need internet access. The technician has a router with four LAN ports and a 24-port unmanaged switch. Which of the following is the correct way to connect the devices to provide internet access to all computers?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Connect the modem to one of the router's LAN ports, then connect the switch to another LAN port, and connect all computers to the switch.
If the modem is connected to a LAN port, the router treats it as a client device, not as an internet source, so it will not route traffic to the WAN or perform NAT for the network.
B
Best answer
Connect the modem to the router's WAN port, then connect the switch to one of the router's LAN ports, and connect all computers to the switch.
This is the standard configuration: the modem provides the public IP to the router's WAN, the router performs NAT to share the connection, and the switch expands the LAN ports for all computers.
C
Distractor review
Connect the modem directly to the switch, then connect the router to the switch, and connect all computers to the router's LAN ports.
Connecting the modem directly to the switch exposes the modem's single public IP to the network, but the switch cannot perform NAT; the router would also be connected incorrectly, likely not getting a public IP.
D
Distractor review
Connect the modem to one of the switch's ports, then connect the router to another switch port, and connect all computers to the router.
Similar to option C, this configuration fails to properly separate the WAN and LAN. The router may get a public IP but network traffic flow would be incorrect, and the router's LAN ports are limited to four.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?
Question 2
A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)
Question 3
A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
Question 4
A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?
Question 5
A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?
Question 6
A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?
FAQ
Questions learners often ask
What does this 220-1101 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Connect the modem to the router's WAN port, then connect the switch to one of the router's LAN ports, and connect all computers to the switch. — The standard setup is to connect the modem to the router's WAN port (for NAT, DHCP, and firewall), then connect the router's LAN port to the switch, and finally connect all computers to the switch. This allows the router to manage the public IP and private network. Option A incorrectly puts the modem on the LAN side, which would not perform NAT. Options C and D place the modem directly on the switch, which typically cannot handle public IP routing and NAT for multiple devices.
