A hospital is designing a new data center to host its electronic health record (EHR) system. The facility is in a region prone to seasonal flooding and occasional grid power outages. The network team is tasked with ensuring the EHR system remains available during a multi-hour power outage while also protecting the physical hardware from water damage. Which combination of physical infrastructure controls should the team prioritize?

Install a gas-based fire suppression system, a UPS, and a backup generator, but keep servers on the ground floor for easier maintenance access.

Use only a backup generator without a UPS, and place all servers in standard floor-mounted racks.

Install an uninterruptible power supply (UPS) and a backup generator, and place server racks on raised flooring with water detection sensors.

Deploy a fire suppression system using water sprinklers and install a single high-capacity HVAC unit for temperature control.

Which physical on-premises infrastructure component is primarily responsible for maintaining the temperature and humidity levels that keep network equipment within its operating range?

Uninterruptible power supply (UPS)

Which cloud service model provides the customer with the most control over the underlying infrastructure, including operating systems and applications?

Infrastructure as a Service (IaaS)

What is the primary function of Network Access Control (NAC)?

To provide secure remote access through VPN tunnels

To monitor network traffic for suspicious activity

To encrypt all data transmitted over the network

To enforce security policies on devices before granting network access

What is the primary purpose of a Memorandum of Understanding (MOU) in the context of network security between two organizations?

To establish a legally binding contract with financial penalties

To outline the general understanding and intent regarding security responsibilities and cooperation

To define the technical specifications of network hardware

To replace the need for any formal security policies
