Full question →mediummultiple choiceObjective-mapped
A change request to apply a critical security patch to a production web server has been approved by the Change Advisory Board (CAB) with a detailed implementation plan. During the scheduled maintenance window, the technician discovers that a required prerequisite patch is missing. The prerequisite patch is available for download and was tested in the lab, but it was not listed in the approved change plan. According to change management best practices, what should the technician do FIRST?
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
Stop and submit a new change request for the prerequisite patch before proceeding
Proper change management dictates that any unapproved change must go through the approval process again to maintain control and documentation.
B
Distractor review
Proceed with the critical patch first, then add the prerequisite in a subsequent change
Installing the patch without the prerequisite may cause the patch to fail or the server to become unstable, and it violates the approved plan.
C
Distractor review
Download and install the prerequisite patch since it was already tested in the lab
Even if tested, the prerequisite was not part of the approved change; implementing it without CAB approval bypasses the change management process.
D
Distractor review
Request an emergency change from the CAB while continuing the implementation
Continuing while waiting for approval is not appropriate; the technician should stop and wait for a decision before making any changes.
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: Stop and submit a new change request for the prerequisite patch before proceeding — The change management process requires that any deviation from the approved plan be evaluated and re-approved before proceeding. Implementing an unapproved change, even if beneficial, risks unanticipated issues and violates the change control policy. The technician should stop work, document the need for the prerequisite, and request a new change approval. Simply proceeding because the patch is tested ignores the formal approval process. Downloading the patch without approval and then deciding later still breaks the process. Requesting an emergency change may be appropriate if the risk is imminent, but the question asks for the FIRST step, which is to stop the current change and seek re-approval.
