An architect is designing a solution based on the following information:

• Each ESXi host has a single physical NIC with two 10 Gbps ports.
• There is a performance-based service-level agreement (SLA) that guarantees 15 Gbps bandwidth for production virtual machines at all times.
• There is no budget to purchase additional hardware.
• The hardware replacement SLA is based on a delivery agreement of two business days.

In a meeting to discuss the minimum viable product (MVP) deployment of a new customer-facing application, the key stakeholder shares details of the application components and the application administrators share details of performance and integrity tests for the application.

The application will be made up of the following components:

• A web server

-Steps to confirm the web server is operating correctly will take 15 minutes after the application server is online.

• An application server

-Steps to confirm application server integrity will take 15 minutes after the database is online.

• A database server

-The database server will be managed by a database administrator, with an agreed service-level agreement (SLA) to restore and validate database services within one hour.

The existing VMware infrastructure offers a recovery point objective (RPO) of 5 minutes and recovery time objective (RTO) of 15 minutes through a combination of backups and replication.

In the event of an outage impacting all three application components, how long will it take for the application to recover and complete all checks?
