A small office network consists of a router (with built-in DHCP server) and an unmanaged switch. All 12 workstations are connected to the switch, and they have internet access. However, users cannot see each other's shared folders over the network. The technician has verified that all workstations are on the same IP subnet (192.168.1.0/24) and can ping each other successfully. Which of the following is the MOST likely cause of this issue?

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

The unmanaged switch is experiencing broadcast storms due to a loop

A broadcast storm would cause severe performance issues and connectivity drops, not a clean situation where ping works but file sharing fails. Since all workstations can ping each other, a loop is unlikely.

B

Best answer

The workstations are configured with different workgroup names

For Windows file sharing to work, all computers must belong to the same workgroup (or domain). If they are in different workgroups, they will not appear in the network browse list, even though they can communicate at the IP level.

C

Distractor review

The router's DHCP lease time is set too short

A short DHCP lease time might cause periodic IP address renewals but would not prevent file sharing while the address is valid. It would not cause a permanent inability to see shared folders.

D

Distractor review

The network cables are not properly crimped to T568B standards

Incorrectly crimped cables typically cause link issues (dropped packets, no connectivity) and would prevent pings from succeeding. Since pings work, the physical layer is fine.

Common exam trap

Common exam trap: usable hosts are not the same as total addresses

Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.

Technical deep dive

How to think about this question

Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.

KKey Concepts to Remember

  • CIDR notation defines the prefix length.
  • Block size helps identify subnet boundaries.
  • Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
  • The required host count determines the smallest suitable subnet.

TExam Day Tips

  • Write the block size before choosing the subnet.
  • Check whether the question asks for hosts, subnets or a specific address range.
  • Do not confuse /24, /25, /26 and /27 host counts.

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?

CIDR notation defines the prefix length.

What is the correct answer to this question?

The correct answer is: The workstations are configured with different workgroup names — When workstations can ping each other but cannot see shared folders, the issue is typically related to network discovery or the workgroup/domain configuration. In Windows environments, file sharing requires all computers to be in the same workgroup or domain. If workgroups differ, networked computers will not appear in the Network list, even though they have IP connectivity. The router and switch are functioning correctly since internet access and ping tests pass.
