A technician is replacing a failed hard drive in a server that uses RAID 1 (mirroring). The server has hot-swappable drive bays, and the operating system continues to function with the remaining drive. Which of the following steps should the technician perform FIRST to restore fault tolerance?
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
Replace both hard drives and restore the data from a recent backup
This is not the correct procedure for RAID 1. The array is still operational with one drive; replacing both is unnecessary and causes downtime. Restoring from backup would be a last resort if both drives failed.
B
Best answer
Remove the failed drive, insert a new drive of equal or larger capacity, and allow the RAID controller to rebuild the mirror automatically
This is the standard procedure for replacing a failed drive in a RAID 1 array. The new drive should be the same size or larger (extra space may not be usable). Most RAID controllers will automatically begin rebuilding once the new drive is detected.
C
Distractor review
Format the new drive in the server's file system before inserting it
Formatting the drive beforehand is not required and may interfere with the RAID rebuild process. The RAID controller will overwrite the drive during the rebuild.
D
Distractor review
Remove the failed drive, insert a new drive, and launch the RAID configuration utility to designate the new drive as a hot spare
Designating a drive as a hot spare is for automatic replacement of a failed drive in the future. In this scenario, the technician is manually replacing the failed drive; the new drive should simply be added to the array to initiate the rebuild.
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: Remove the failed drive, insert a new drive of equal or larger capacity, and allow the RAID controller to rebuild the mirror automatically — In RAID 1, when a drive fails, the array continues to operate in a degraded state. To restore redundancy, the failed drive must be replaced with a new one, and the RAID controller will automatically rebuild the mirror onto the new drive. The technician should first identify the failed drive (often indicated by a status LED) and then physically remove it and install a new drive of equal or larger capacity. Formatting the drive or replacing both drives is unnecessary; the array is meant to survive a single drive failure.
