A growing e-commerce company is considering various strategies to ensure its web servers can handle sudden traffic surges without an impact on site availability. The company is assessing methods that distribute incoming traffic across multiple servers. Which strategy should the company implement to dynamically allocate the load based on real-time traffic and server conditions?

Active load balancing

What is a primary function of application clustering in a network?

It allows servers in the cluster to communicate session information to one another.

You have been asked to deploy a network solution that includes an alternate location where operational recovery is provided within minutes of a disaster. Which of the following strategies would you choose?

Hot swapping

An organization operates a large data center that supports critical business operations. Recently, the organization has struggled with frequent power interruptions leading to downtime and data loss. To address this issue, the chief information security officer (CISO) decides to review the data center's resilience and recovery strategies, particularly emphasizing backup power. To increase the resilience and recovery capabilities of the data center and ensure operations continue even during a power failure, which of the following options should the CISO consider? (Select two.)

Implement a UPS. Deploy a dual power supply unit in each server.

A security consultant assesses a company's server room to determine how well it can maintain operations during power interruptions. The consultant evaluates the integration of power distribution units (PDUs) and backup power generators within the security architecture. Considering the goal of ensuring resilience and recovery in the server room during power interruptions, which primary role does the backup power generator play in conjunction with the PDU?

It provides a prolonged source of power to the PDUs after the UPS system depletes its immediate resources.

A data center manager is evaluating the resilience and recovery capabilities of a company's server room. The manager wants to ensure that in the event of power fluctuations or outages, the company's servers remain operational and maintain data integrity. The manager focuses on the role of power distribution units (PDUs) and Uninterruptible Power Supplies (UPSs) in this context. In enhancing the resilience and recovery capabilities of the server room against power interruptions, which primary function does the UPS provide to the servers that directly support this goal?

It provides temporary power during an outage, allowing for a graceful shutdown or transition to backup generators.

A growing e-commerce company wants to implement a strategy that evenly distributes incoming traffic across multiple servers without constantly monitoring server loads or making adjustments based on real-time conditions. Which strategy should this company implement to manage load distribution in this manner?

Passive load balancing

What is a significant advantage of using an active/passive clustering configuration in a network?

The performance is not adversely affected during failover.

What is the primary function of the Common Address Redundancy Protocol (CARP) in a network?

To enable the active node to "own" the virtual IP and respond to connections.

To prevent server downtime, which of the following components should be installed in a server system redundantly?

Uninterrupted power supply
