Fault Tolerance and High Availability Flashcard

Front

Which of the following best describes the purpose of a load balancer in a fault-tolerant network?
Options:
Reduces the cost of deploying multiple servers,
Ensures uninterrupted access by distributing traffic across multiple servers,
Eliminates the need for high-availability configurations,
Maintains uptime by clustering physical servers into one logical unit

Back

Ensures uninterrupted access by distributing traffic across multiple servers

Front

What is the primary benefit of using RAID in a server?

Back

Provides fault tolerance for storage devices

Front

When designing a fault-tolerant network, what is a key consideration for high availability?

Back

Automatic failover mechanisms

Front

In a system with LBFO (Load Balancing Fail Over), what happens if one network interface card (NIC) fails?

Back

The remaining NICs take over to maintain connectivity.

Front

How does using multiple internet providers contribute to fault tolerance?

Back

Ensures connectivity if one provider fails

Front

Why is multipathing considered a robust high-availability solution?

Back

It allows each NIC to connect to a separate switch.

Front

What role does a virtual IP (VIP) play in a load balancer configuration?

Back

Represents the public-facing IP for incoming connections

Front

Which redundancy feature ensures uptime in case of a single server's power supply failure? Options: Load balancing, Multipathing, Redundant power supplies, RAID

Back

Redundant power supplies

Front

In a high-availability firewall setup, what happens during an automatic failover?

Back

A secondary firewall takes over without interruption

Front

High-availability systems often involve redundant components to minimize downtime.

Back
