They are <strong>physically separate data centers<\/strong> within a region, designed to be <strong>isolated from failures<\/strong> in other zones while still connected through low-latency networks.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Why the correct answer is <strong>Fault tolerance<\/strong>:<\/h3>\n\n\n\n<p><strong>Fault tolerance<\/strong> refers to a system&#8217;s ability to continue operating properly in the event of the failure of some of its components. By distributing applications across <strong>multiple availability zones<\/strong>, cloud providers can ensure that if one zone experiences a hardware failure, power outage, or natural disaster, the workload can continue to operate from another zone. This architecture is key to <strong>high availability<\/strong> and <strong>disaster recovery<\/strong>.<\/p>\n\n\n\n<p>For example, in AWS, if you deploy your application servers in <strong>three different availability zones<\/strong>, and one zone fails, traffic can be routed to the remaining zones without affecting the end-user experience. This design <strong>minimizes downtime<\/strong> and maintains business continuity.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Why the other options are incorrect:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. More visibility<\/strong>: Availability zones do not inherently improve visibility into your resources. Visibility is more related to monitoring tools, logs, and observability services (like AWS CloudWatch or Azure Monitor).<\/li>\n\n\n\n<li><strong>c. Lower cost<\/strong>: Using multiple availability zones might actually increase cost because you&#8217;re provisioning resources in more than one zone. Fault tolerance and high availability often come with <strong>higher costs<\/strong>, not lower.<\/li>\n\n\n\n<li><strong>d. Less redundancy<\/strong>: Availability zones are <strong>specifically designed to increase redundancy<\/strong>, not reduce it. Redundancy ensures that backup systems or data centers are available if the primary one fails.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>Using availability zones is a best practice in cloud architecture to <strong>enhance fault tolerance<\/strong>, ensuring applications remain available and resilient even during localized failures.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following can be achieved using availability zones in cloud computing?a.
