By running the same task multiple times until it succeeds.

By using retry logic for failed tasks.

By checking the current state before applying changes.

By defining a specific retry count in the playbook.

When using AWS CDK, what is a common anti-pattern?

Using stacks for resource grouping

Hardcoding resource configurations instead of using reusable constructs

Defining resources in a modular format

Leveraging environment-specific parameters

What is the difference between a static and a shared library?

A static library is linked at compile time, while a shared library is linked at runtime

A static library can only be used in single-threaded applications, whereas a shared library supports multithreading

A static library is linked at compile time, while a shared library is linked at runtime

A static library is smaller in size than a shared library

You deploy a containerized application in Docker, and it frequently fails to resolve external domain names despite the host system having a working DNS configuration. Upon investigation, the issue persists even after explicitly setting a custom DNS server for the container. Which internal configuration file within the container is likely being dynamically managed and causing the issue, requiring a specific override during container runtime to fix it?

/etc/hosts

/etc/resolv.conf

/etc/network/interfaces

/etc/sysconfig/network-scripts/ifcfg-docker

When planning for disaster recovery in AWS RDS, which storage option is most appropriate?

Provisioned IOPS SSD for critical applications

Magnetic storage for lower cost

Throughput-optimized HDD for large datasets

Cold HDD for archival purposes

14 / 25

In a hybrid cloud setup with AWS and GCP, how can you ensure consistent firewall rules for a disaster recovery environment?

Enable firewall rules only in the primary cloud until a disaster occurs

Use a centralized management tool like Terraform to deploy firewall rules across both clouds

Manually configure each rule in the respective cloud consoles

Disable egress traffic restrictions to simplify rule management

You need to establish communication between a private server in AWS and a private server in Azure. Both servers are located in isolated environments under different accounts, with strict security policies in place. The communication must be secure and minimize the risk of policy conflicts, especially with outbound traffic from AWS. What’s the most efficient way to ensure smooth connectivity without exposing internal services or violating strict security policies in both environments?

Use the NAT Gateway IP in the security group.

Allow direct connections using an inter-cloud VPC link.

Expose the AWS instance via a public IP.

Use VPC Peering and allow traffic from the peered VPC.

18 / 25

How do you ensure that logs from a Docker container persist even after the container is deleted?

Use a logging volume or external logging service.

Use the --log-driver option.

Redirect logs to a file inside the container.

Enable the --persist-logs flag.

What is the difference between a static and a shared library?

A static library is smaller in size than a shared library

A static library can only be used in single-threaded applications, whereas a shared library supports multithreading

A static library is linked at compile time, while a shared library is linked at runtime

A static library does not require a linker, while a shared library does
