Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites. The sites are 100 miles (160 km) apart and target RPO/RTO are 3 hrs and 24 hrs, respectively. Which two considerations must Company XYZ bear in mind when deploying replication in their scenario? (Choose two.)
Company XYZ must consider routing VSANs between sites to isolate fault domains and increase overall availability. This ensures that issues in one site do not affect the other, maintaining reliable performance. Also, asynchronous data replication should be used to meet the business requirements without impacting the performance of the primary site, especially given the 100-mile distance and the RPO/RTO targets of 3 hours and 24 hours respectively, which are achievable within this setup.
An architect receives a business requirement from a CTO that states the RTO and RPO for a new system should be as close as possible to zero. Which replication method and data center technology should be used?
To achieve a Recovery Time Objective (RTO) and Recovery Point Objective (RPO) as close as possible to zero, synchronous replication is required because it ensures data is written to both primary and backup systems simultaneously. Metro Ethernet is a high-speed, low-latency network technology that supports synchronous replication between data centers located within a metropolitan area. This minimizes latency and ensures that data consistency is maintained, making it the most suitable choice for minimizing both RTO and RPO.
What are two primary design constraints when a robust infrastructure solution is created? (Choose two.)
When creating a robust infrastructure solution, two primary design constraints are the project time frame and the total cost. The project time frame addresses how soon the solution needs to be implemented, impacting decisions on technology and resource allocation. Total cost is also crucial as budgetary limitations influence which components and technologies can be utilized. These factors are pivotal in ensuring the infrastructure solution meets both operational and financial requirements.
Which network management framework can be used to develop a network architecture that contains business requirements analysis, gap analysis, and network diagrams as artifacts to be used for design and implementation later?
The Open Group Architecture Framework (TOGAF) is designed to develop and implement precise IT infrastructure aligned with business requirements. It involves business requirements analysis, gap analysis, and generates network diagrams necessary for comprehensive design and implementation phases. This broad framework supports aligning the IT infrastructure with the business strategy and goals, which matches the question's criteria.
Which two types of planning approaches are used to develop business-driven network designs and to facilitate the design decisions? (Choose two.)
To develop business-driven network designs and facilitate the design decisions, two planning approaches are typically employed: the strategic planning approach and the tactical planning approach. The strategic planning approach focuses on long-term goals and strategies, ensuring that the design aligns with the future directions and needs of the business. The tactical planning approach, on the other hand, addresses immediate issues or short-term goals, providing a quick response to current needs without necessarily considering long-term impacts. These two approaches together help create a balanced and effective network design that meets both current and future business requirements.
