Full question →mediummultiple choiceObjective-mapped
A small business wants to deploy a customer relationship management (CRM) application for its sales team. The company wants to avoid managing servers, operating systems, or application patches. The sales team needs to access the CRM through a web browser from any device. The company prefers a monthly subscription model based on the number of users. Which cloud service model BEST fits these requirements?
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
Infrastructure as a Service (IaaS)
IaaS provides virtualized computing resources (VMs, storage, networking) but the customer is still responsible for managing the operating system and applications. This does not fulfill the requirement to avoid managing servers and OS patches.
B
Distractor review
Platform as a Service (PaaS)
PaaS provides a platform for customers to develop, run, and manage applications without dealing with underlying infrastructure. However, the customer must still develop or deploy their own application, not use a ready-made SaaS application like CRM.
C
Best answer
Software as a Service (SaaS)
SaaS delivers fully functional applications over the internet, managed by the provider. Users access the CRM via a browser, the vendor handles all maintenance and updates, and billing is typically per-user per-month. This perfectly matches the scenario.
D
Distractor review
Desktop as a Service (DaaS)
DaaS provides virtual desktops hosted in the cloud. While the company could install CRM on those desktops, it still requires managing the desktop OS and applications. It does not provide a ready-to-use CRM application directly.
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: Software as a Service (SaaS) — Software as a Service (SaaS) delivers ready-to-use applications over the internet, managed entirely by the provider. This matches the requirement of avoiding server management and patching while providing browser-based access with per-user subscription billing. Infrastructure as a Service (IaaS) would require managing VMs and OS patches. Platform as a Service (PaaS) is for developing and deploying custom applications, not for consuming ready-made software. Desktop as a Service (DaaS) provides virtual desktops, not specific business applications.
