• Diagnostic tools – Practical application of tools such as traceroute, tcpdump, netstat, and Wireshark.
• Incident response – Your systematic methodology for isolating issues in high-pressure situations.
• Advanced concepts (less common) – Analyzing BGP routing anomalies, diagnosing packet fragmentation issues, and troubleshooting hybrid VPN connections.

Example questions or scenarios:

• "A application server suddenly loses connectivity to a database cluster across a hybrid cloud network. Walk me through your first five troubleshooting steps."
• "How would you identify and mitigate a suspected DDoS attack affecting a public-facing API gateway?"

Multi-Cloud Management & Resource Optimization

Modern financial systems rely on a mix of on-premises infrastructure and public cloud providers. You must demonstrate your ability to manage, scale, and optimize resources across diverse environments like AWS, Azure, or private cloud setups.

Be ready to go over:

• Cloud architecture – Designing resilient, multi-region architectures that support high availability.
• Resource allocation – Strategies for monitoring, scaling, and optimizing compute and storage costs.
• Infrastructure as Code (IaC) – Using tools like Terraform or CloudFormation to manage cloud lifecycles.
• Advanced concepts (less common) – Implementing zero-trust security models in multi-tenant cloud environments and managing cross-cloud data replication latency.

Example questions or scenarios:

• "Describe how you would design a highly available application infrastructure across two cloud providers to ensure continuous operations if one provider experiences an outage."
• "How do you identify underutilized resources in a cloud environment, and what steps do you take to safely downsize them?"

Database Administration & Data Integrity

For roles focused on database administration, or general systems roles supporting transaction pipelines, maintaining database health and performance is paramount.

Be ready to go over:

• Performance tuning – Identifying query bottlenecks, optimizing indexes, and managing database locks.
• High availability – Configuring replication, clustering, and failover mechanisms.
• Security & compliance – Ensuring data encryption at rest and in transit, and managing access controls.
• Advanced concepts (less common) – Resolving deadlocks in high-frequency transactional environments and managing database sharding across distributed regions.

Example questions or scenarios:

• "A critical transactional database is experiencing severe locking issues, delaying payment processing. How do you identify the blocking query and resolve the issue safely?"
• "Explain how you would design a disaster recovery strategy for a multi-terabyte SQL database with an RTO of less than 15 minutes."
