Writing and maintaining application code

Answer

Defining which users can access the company's applications

Answer

Backing up the company's application data

Question 5

An organization wants to modernize its on-premises applications. The IT team identifies three types of applications: legacy apps that can only move with significant refactoring, custom-built apps that can be containerized and moved as-is, and applications that can be replaced entirely by SaaS solutions. This categorization approach is called what?

Accepted Answer

Application portfolio assessment using migration strategies (the 6 Rs framework). The scenario describes categorizing applications based on their migration path: legacy apps requiring refactoring, custom apps suitable for containerization, and apps replaceable by SaaS. This directly aligns with the '6 Rs' framework (Rehost, Replatform, Refactor, Repurchase, Retire, Retain) used in application portfolio assessment for cloud migration. Option B is correct because the 6 Rs provide a structured way to evaluate and classify each application's optimal migration strategy.

Question 7

What is virtualization in the context of cloud computing, and why is it fundamental to how cloud providers deliver services?

Accepted Answer

Virtualization abstracts physical hardware into multiple isolated virtual machines, enabling many customers to share physical infrastructure efficiently and securely.. Virtualization is fundamental to cloud computing because it decouples the operating system and applications from the underlying physical hardware through a hypervisor (e.g., VMware ESXi, KVM, Hyper-V). This abstraction allows a single physical server to host multiple isolated virtual machines (VMs), each with its own guest OS, enabling cloud providers to achieve high resource utilization, multi-tenancy, and rapid provisioning. Without virtualization, providers would be limited to one OS per physical server, drastically reducing efficiency and scalability.

Answer

Virtualization is the process of converting physical servers into digital images for backup purposes.

Answer

Virtualization is a networking technique that routes internet traffic more efficiently.

Answer

Virtualization is a backup strategy where data is stored in multiple geographic locations.

Question 9

A large enterprise runs a critical application on Google Cloud consisting of Compute Engine instances behind a TCP load balancer. The application experiences intermittent slow response times that last for about 10 minutes before returning to normal. This pattern has been occurring every few days at random times. The operations team has configured Cloud Monitoring alerts for CPU and memory, but no alerts have fired. They have also reviewed the load balancer logs and see no errors, but the latency spikes. The application logs show no errors during these periods. The team suspects a resource bottleneck but cannot find it. Further investigation reveals that the application makes synchronous calls to an external authentication service for each request. What is the most likely cause and corrective action?

Accepted Answer

The application is making synchronous calls to an external authentication service that occasionally has latency spikes; implement caching and asynchronous processing.. The intermittent latency spikes lasting ~10 minutes, with no errors in application or load balancer logs and no CPU/memory alerts, point to an external dependency issue. The synchronous calls to the external authentication service are the likely bottleneck: if that service experiences transient latency, every request is blocked, causing the application's response time to spike. Caching authentication tokens and using asynchronous processing (e.g., a queue or background refresh) decouples the application from the external service's variability, eliminating the cascading latency.

Answer

The TCP load balancer is experiencing connection draining issues; switch to a proxy-based load balancer.

Answer

The instance group's autoscaler is configured with a cooldown period that is too long; reduce the cooldown period.

Answer

The virtual machine instances are suffering from CPU throttling due to sustained use of burstable CPU; move to a machine type with more CPUs.

Question 10
