Full question →mediummulti selectObjective-mapped
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.)
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
Best answer
Run 'ipconfig /release' followed by 'ipconfig /renew'
This command sequence forces the workstation to release the APIPA address and request a new IP from a DHCP server. Often this resolves temporary DHCP communication issues.
B
Best answer
Check that the DHCP server is operational and reachable on the network
If the renew command fails, the next step is to ensure the DHCP server is running, has available addresses, and is in the same broadcast domain or that DHCP relay is configured correctly.
C
Distractor review
Disable the Windows Firewall
Firewall settings are not related to DHCP address assignment. The firewall could block certain traffic but does not cause the workstation to obtain an APIPA address.
D
Distractor review
Replace the network interface card (NIC)
A faulty NIC usually causes no connectivity or link drops. An APIPA address indicates the NIC is functional but cannot reach the DHCP server. Replacing the NIC is not a first step.
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 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 3
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 4
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 5
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?
Question 6
A cloud administrator needs to increase the amount of RAM allocated to a running virtual machine (VM) from 4GB to 8GB to handle a temporary workload spike. The administrator logs into the cloud management console, selects the VM, and changes the instance type to one with 8GB of RAM. The change takes effect immediately without requiring a reboot. Which cloud computing characteristic does this scenario BEST illustrate?
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: Run 'ipconfig /release' followed by 'ipconfig /renew' — An IP address starting with 169.254.x.x is an Automatic Private IP Addressing (APIPA) address, assigned when the DHCP server is unreachable. The technician should first attempt to renew the IP address (ipconfig /release and ipconfig /renew) to contact the DHCP server again. If that fails, the DHCP server itself or the network path to it should be checked. Checking the firewall or replacing the NIC are premature without first addressing the DHCP issue.
