A cloud service provider is deploying a new multi-tenant web application. The architecture must ensure that a single noisy tenant cannot degrade the experience of other tenants, and it must allow for seamless scaling during peak hours. The application is stateless. What is the most appropriate application delivery architecture?

Implement a web application firewall (WAF) in front of the application to filter malicious traffic and rely on the application to handle load.

Deploy a layer-4 load balancer that distributes traffic based on source IP hash to a fixed pool of application servers.

Deploy a layer-7 load balancer with per-tenant rate limiting and connection queuing, backed by an auto-scaling group of application servers.

Use a global server load balancer (GSLB) to route users to the nearest data center, but do not implement any local traffic management.

A cloud provider is launching a new object storage service. The service must be highly durable and available, and it must handle sudden, massive spikes in write traffic. The application delivery and storage architecture should be designed to:

Use a single, centralized storage cluster with a layer-4 load balancer to distribute requests to storage nodes.

Deploy a front-end layer of stateless API gateways with a layer-7 load balancer, backed by a distributed storage cluster that replicates data across multiple availability zones.

Use a single powerful storage array with synchronous replication to a secondary site and a DNS-based round-robin for load distribution.

Implement a multi-region, eventually-consistent storage system with a global load balancer that routes writes to the nearest available region.

A green-field data center is being designed for a cloud provider that will offer high-performance computing (HPC) services. The HPC workloads are highly sensitive to network latency and jitter. Which network design consideration is most important?

Using a large number of virtual LANs (VLANs) to segment traffic.

Implementing a low-latency, high-bandwidth fabric such as InfiniBand or a high-performance Ethernet fabric with low oversubscription.

Relying on a software-defined network (SDN) controller to manage all traffic flows.

Using a standard Ethernet network with a tree topology.

Why is it important for data center infrastructure and application delivery architecture to be aligned in a cloud service provider environment?

To ensure that application performance and reliability are supported by adequate network and compute resources

To eliminate the need for security controls

To simplify the application code

To reduce the number of data centers required
