You are a database administrator for an organization that uses Azure SQL Database for its operations. The organization has a strict data retention policy and has set up the following backup strategy:
            
            1. Full backups are taken every Sunday at midnight.
            2. Differential backups are taken every day at midnight, excluding Sunday.
            3. Transaction log backups are taken every hour on the hour.
            
            On Wednesday at 2:30 PM, a failure occurred, and the latest backup files available are: full backup from the previous Sunday, differential backups for Monday and Tuesday, and transaction log backups up to Wednesday 2 PM.
            
            In order to restore the database to the most recent point in time with the minimum amount of data loss, in what order should you restore the backups?
A: Restore the full backup, then the differential backup for Tuesday, then the differential backup for Wednesday, then each transaction log backup from midnight on Wednesday to 2 PM on Wednesday.
            
            B: Restore the full backup, then the differential backup for Wednesday, then each transaction log backup from midnight on Wednesday to 2 PM on Wednesday.
            
            C: Restore the full backup, then each differential backup from Monday and Tuesday, then each transaction log backup from midnight on Wednesday to 2 PM on Wednesday.
            
            D: Restore the full backup, then the differential backup for Monday, then each transaction log backup from midnight on Monday to 2 PM on Wednesday.
            
            E: Restore the full backup, then the differential backup for Tuesday, then each transaction log backup from midnight on Tuesday to 2 PM on Wednesday.

Resolving Connection Issues

You are an Azure Administrator and you manage a Linux VM running an internal web application in Azure. The web application communicates with a database server hosted on another VM in the same Virtual Network (VNet).
            
            Recently, users have reported that the web application is not accessible. After initial troubleshooting, you have identified that the web application VM is unable to establish a connection with the database server VM on port 5432.
            
            You have checked and confirmed the following:
            
            1. Both VMs are up and running without any issues.
            2. Both VMs are located in the same VNet and subnet.
            3. Both VMs can successfully ping each other.
            4. A Network Security Group (NSG) is associated with the subnet, and it has a rule allowing all outbound traffic from the web application VM.
            5. The NSG rule for inbound traffic to the database VM on port 5432 has a higher priority than the default deny all rule.
            
            Given the information provided, what could be the most likely reason for the issue and the appropriate resolution?
A: Add a route table to the subnet to enable communication between the VMs.
            
            B: The NSG rule priority for the inbound traffic to the database VM is not set correctly. Adjust the priority to be lower than the default rule.
            
            C: Check if a firewall is enabled on the database VM that might be blocking the port. If so, configure it to allow connections on port 5432.
            
            D: The issue is related to the DNS resolution. Update the DNS settings in the VNet to enable name resolution between the VMs.
            
            E: The web application is not correctly configured to connect to the database. Update the connection string in the web application configuration.

Resolving NSG Configuration Issues

You are an Azure Administrator in a software development company. A Linux VM is deployed on Azure, hosting an application server running on port 5000, set to start whenever the VM is booted up.
            
            The VM is associated with a Network Security Group (NSG) having the following inbound security rules:
            
            - Rule 100 (Priority: 100): Allow SSH (port 22) from any source
            - Rule 200 (Priority: 200): Allow HTTP (port 80) from any source
            - Rule 400 (Priority: 400): Allow TCP traffic on port 5000 from any source
            - Rule 300 (Priority: 300): Deny all inbound traffic from any source
            
            The outbound security rules are configured to allow all traffic to any destination.
            
            Internal users have been attempting to connect to the application server on port 5000 but they are consistently facing connection timeouts. You've confirmed the application server is up and running, and you can connect to the server locally on the VM.
            
            What is the most probable cause of the problem and how would you fix it?
A: The inbound rule to allow TCP traffic on port 5000 is conflicting with the rule to allow HTTP on port 80. Remove Rule 200.
            
            B: Rule 300 to deny all inbound traffic is being processed before Rule 400 to allow traffic on port 5000. Modify the priority of Rule 400 to a value less than 300.
            
            C: The application server should be configured to listen on a well-known port instead of port 5000. Change the server settings.
            
            D: The NSG is missing an inbound rule to allow ICMP traffic. Add a new rule with a lower priority.
            
            E: The NSG needs to have an outbound rule specifically allowing traffic to port 5000. Add a new outbound rule.
