Scenario:Migrating a stand-alone application storing PII to the cloud.

Data to Encrypt:Data at rest(Option B) should be encrypted:

Data in transit (Option A) and backups (Option C) are also important but not the primary concern here.

Data archives (Option D) may or may not contain sensitive data.

Scenario:Four disks, requiring redundancy and maximum usable capacity.

RAID Level:RAID 10(Option D) is the best choice:

RAID 10 combines mirroring (redundancy) and striping (performance).

RAID 0 lacks redundancy, RAID 1 provides less capacity, and RAID 5 requires more

Enabling open file backups allows the backup software to copy files that are currently open or in use by applications. This ensures that even if a file is actively being modified during the backup process, it will still be included in the backup.

Advantages:

Ensures consistency of backed-up data, especially for files that are frequently accessed or modified.

Prevents data loss due to files being skipped during backup.

Microsoft Docs: Volume Shadow Copy Service (VSS)

When a server is acting strangely after a patch and services that should be enabled are disabled, it's often a good first step to set the services to restart automatically and then reboot the server.This can resolve many issues as it ensures that all services start correctly upon reboot

If the network cable is functioning but there is no network connectivity, the next step would be to check the IPv4 options. This includes verifying that the server has a correct IP address, subnet mask, and gateway configuration.

IPv4 options (Answer B): Incorrect IP configuration is a common reason for network connectivity issues.

NIC firmware (Option A): Firmware issues are less likely if the NIC is detecting the cable and appears operational.

DHCP options (Option C): DHCP could be checked if automatic IP assignment is being used, but verifying IPv4 options manually is the first step.

Firewall options (Option D): Firewalls can block connectivity but should be checked after confirming IP settings.

DNS settings (Option E): DNS issues usually affect domain name resolution, not basic network connectivity.

A full backup captures all data, regardless of whether it has changed since the last backup. This ensures that a complete copy of the data is made every time.

Full (Answer E): A full backup includes every file in the system, regardless of changes.

Incremental (Option A): Backs up only files that have changed since the last backup (full or incremental).

Differential (Option B): Backs up all files changed since the last full backup.

Archive (Option C): Typically refers to long-term storage of data, not a type of backup process.

Snapshot (Option D): Captures the system's state at a given point in time, often used in virtual environments.

P2V (Physical to Virtual) refers to converting a physical server into a virtual machine, which can then be deployed to a remote cloud environment. This is the best method for duplicating a physical server to a virtual environment for disaster recovery.

P2V (Answer B): This is the process of converting a physical server to a virtual machine for migration to the cloud.

V2V (Option A): Refers to virtual-to-virtual migration, which is not applicable in this case.

V2P (Option C): Refers to converting a virtual machine back to physical, which is not needed here.

P2P (Option D): Physical-to-physical migration is not relevant for cloud-based disaster recovery.

The server's local storage is experiencing problems. Only two out of four drives are found, and an additional hard drive connects and disconnects randomly.

Likely Cause:The most probable cause is a faultypower supply(Option B). Here's why:

When a power supply is failing or not providing sufficient power, it can lead to intermittent connectivity issues with drives.

Drives may not be recognized during boot or may disconnect randomly due to power fluctuations.

RAM, CPU, and cooling failures typically result in different symptoms (e.g., blue screens, system instability, or overheating), which do not match the described issue.

A faulty PSU needs replacement, and the management team wants a solution to prevent future downtime.

Solution:Implementredundancy(Option D):

Redundant power supplies ensure that if one fails, the other takes over seamlessly.

Separate circuits, load balancing, and server monitoring are important but do not directly prevent PSU failures.
