An architect is designing an IBM Cloud solution for a mid-market SaaS company. The application must support 500 concurrent users with potential 10x growth, be cost-effective initially, and resilient.

What cloud architecture approach should the architect take?

A) Design for 5,000 users from day one with maximum resources
B) Design a scalable architecture using managed services (Code Engine or Kubernetes with HPA for auto-scaling, Cloud Databases with scaling capability, VPC with security groups), configure for the current 500-user load with auto-scaling to handle growth, implement multi-zone deployment for resilience, and use IBM Cloud Cost Estimator to validate the cost profile
C) Use the smallest possible single-zone configuration to minimize costs
D) Deploy on bare metal servers for maximum performance

 

Correct answers: B – Explanation:
Scalable managed services with auto-scaling balance current cost with growth readiness. Max resources now (A) wastes budget. Single-zone minimal (C) lacks resilience. Bare metal (D) requires more operational overhead.

The architect must decide between IBM Cloud VPC and Classic infrastructure for the deployment.

Which factors should drive the decision?

A) Always choose Classic since it has been available longer
B) Evaluate VPC’s advantages: native security groups for micro-segmentation, custom route tables, flow logs for monitoring, integration with modern IBM Cloud services—versus Classic’s VLAN-based networking. For new deployments, VPC is generally recommended for its security features and modern architecture
C) Deploy half on each for redundancy
D) Choose based on which interface the team prefers visually

 

Correct answers: B – Explanation:
VPC’s security and integration advantages make it the recommended choice for new deployments. Classic longevity (A) is not a technical advantage. Split deployment (C) adds complexity. UI preference (D) is not an architectural criterion.

The application requires a relational database. The architect must choose between IBM Cloud Databases for PostgreSQL and self-managed PostgreSQL on a virtual server.

What factors should inform the database selection?

A) Always choose self-managed for maximum control
B) Evaluate operational overhead: managed databases handle patching, backups, scaling, and HA automatically with IBM managing the underlying infrastructure, while self-managed provides more control but requires the team to handle all operations. For a mid-market company with limited ops staff, managed databases typically provide better value
C) Managed databases are always more expensive
D) Use a NoSQL database instead since it is more modern

 

Correct answers: B – Explanation:
Managed vs self-managed evaluation based on ops capacity provides practical guidance. Always self-managed (A) ignores operational burden. Cost claims (C) ignore the total cost including ops labor. NoSQL (D) is not appropriate for all relational data.

The architect must design the security architecture for the SaaS application.

What security layers should be implemented?

A) Rely entirely on the VPC perimeter security
B) Implement defense-in-depth: VPC security groups at instance level, network ACLs at subnet level, IAM with MFA for user access, encryption at rest using Key Protect, TLS for all data in transit, Activity Tracker for audit logging, and Security and Compliance Center for continuous posture monitoring
C) Implement only application-level authentication
D) Disable security features to improve performance

 

Correct answers: B – Explanation:
Multi-layer defense-in-depth provides comprehensive protection. Perimeter only (A) and app-auth only (C) leave gaps. Disabling security (D) is never acceptable.

The application must be available across two IBM Cloud zones within a region for high availability.

How should the multi-zone deployment be designed?

A) Deploy to a single zone and add a second zone later
B) Deploy application instances across two availability zones behind a public Application Load Balancer, configure the database with cross-zone replication for data availability, use zone-aware persistent storage, and test failover by simulating a zone outage to validate the design
C) Deploy an active-passive configuration with manual failover
D) Run the application in one zone with backup in another region

 

Correct answers: B – Explanation:
Active-active multi-zone with ALB provides automatic failover within the region. Single zone initially (A) lacks HA. Active-passive with manual failover (C) introduces RTO delay. Cross-region (D) is for DR, not HA.

The architect needs to estimate and optimize the monthly cloud cost for the initial deployment.

What cost optimization strategies should be applied?

A) Provision the largest instance sizes to avoid future resizing
B) Right-size compute instances based on actual workload requirements, use reserved capacity pricing for predictable production workloads, leverage auto-scaling to scale down during low-traffic periods, implement Cloud Object Storage for cost-effective static asset storage, and review usage patterns monthly to identify optimization opportunities
C) Use only the free tier services for production
D) Ignore costs during the initial deployment and optimize later

 

Correct answers: B – Explanation:
Right-sizing, reserved pricing, auto-scaling, and storage tiering optimize costs from the start. Over-provisioning (A) wastes budget. Free tier (C) has limitations unsuitable for production. Ignoring costs (D) leads to budget overruns.

The architect must design the hybrid-cloud connectivity between the SaaS application on IBM Cloud and the company’s on-premises data center.

What connectivity design is appropriate?

A) Use the public internet for all on-premises to cloud communication
B) Evaluate the connectivity requirements: Direct Link for dedicated, low-latency private connectivity if the workload requires consistent bandwidth, or VPN for cost-effective encrypted connectivity for lighter traffic, configure Transit Gateway for routing between VPC and on-premises, and implement redundant connections for reliability
C) Install a physical cable between the data center and IBM Cloud
D) Deploy on bare metal servers for maximum performance

 

Correct answers: B – Explanation:
Requirements-based selection between Direct Link and VPN with redundancy provides appropriate connectivity. Public internet (A) lacks guaranteed bandwidth. Physical cables (C) are not how cloud connectivity works. Avoiding hybrid (D) may not be possible if on-premises data is required.

The company wants infrastructure-as-code for repeatable deployments.

What IaC approach should the architect recommend?

A) Document manual Console steps in a wiki
B) Implement Terraform with IBM Cloud Schematics, organize code into modules for networking, compute, database, and security components, use variable files for environment-specific configurations, store code in Git with pull request reviews, and test changes in a development workspace before applying to production
C) Use shell scripts that call the IBM Cloud CLI
D) Allow each engineer to provision resources through the Console independently

 

Correct answers: B – Explanation:
Scalable managed services with auto-scaling balance current cost with growth readiness. Max resources now (A) wastes budget. Single-zone minimal (C) lacks resilience. Bare metal (D) requires more operational overhead.

The architect must plan for disaster recovery with RPO of 1 hour and RTO of 4 hours.

What DR strategy meets these requirements?

A) Rely on multi-zone HA as the complete DR solution
B) Configure cross-region backup replication for the database with point-in-time recovery capability, store application artifacts and IaC templates in a secondary region, create automated DR runbooks that provision the application stack from IaC in the DR region, and conduct quarterly DR drills to validate the 4-hour RTO
C) Back up everything to tape and store it off-site
D) Accept that DR is too expensive and operate without it

 

Correct answers: B – Explanation:
Cross-region backup with IaC-based recovery meets the RPO/RTO targets. Multi-zone HA (A) does not protect against regional outages. Tape backup (C) cannot meet a 1-hour RPO. No DR (D) exposes the business to unacceptable risk.

The architect must present the proposed architecture to the company’s leadership team for approval.

What should the architecture presentation include?

A) Only a detailed technical diagram
B) Include the business requirements addressed by the architecture, a clear architecture diagram with component descriptions, the security and compliance approach, cost estimates with growth projections, the scalability strategy, the DR plan with RPO/RTO targets, identified risks with mitigations, and a phased implementation timeline
C) A verbal description without visual aids
D) Only the cost estimate since leadership cares about budget

 

Correct answers: B – Explanation:
A comprehensive presentation covering business alignment, technical design, security, cost, and risk provides leadership with the full picture. Technical-only (A) misses business context. No visuals (C) makes complex architectures hard to understand. Cost-only (D) ignores critical architecture decisions.
