An enterprise plans to evolve from a traditional WAN network to a software-defined WAN network. The existing devices have limited capability when it comes to virtualization. As the migration is carried out, enterprise applications and services must not experience any traffic impact. Which implementation plan can be used to accommodate this during the migration phase?

• A. Deploy SD-WAN edge routers in the data center, deploy controllers, and migrate branch sites.
• B. Deploy controllers, deploy SD-WAN edge routers in the data center, and migrate branch sites.
• C. Migrate data center WAN routers, migrate branch sites, and deploy SD-WAN edge routers.
• D. Migrate branch sites, migrate data center WAN routers, and deploy controllers.

Budget is one of the important factors when you design a network Regardless of who controls the budget, one common network design goal is to contain costs Reduced budgets or limited resources often force network designers to select the most affordable solution instead of the best solution Which two elements must be considered when you do ROI analysis for the network design that explains how quickly the new network w ill pay for itself' (Choose two. )

• A. state-of-the art technologies
• B. reduced operational costs
• C. improved employee productivity
• D. limiting higher revenue potential
• E. market segmentation

Cost is often one of the motivators for a business to migrate from a traditional network to a software-defined network. Which design decision is directly influenced by CAPEX drivers?

• A. Complexity
• B. Stability
• C. Manageability
• D. Scalability

A leading financial services provider offering a wide range of services to millions of customers worldwide have seen substantial growth over the recent years Now their existing on-premises network infrastructure is struggling to cope with the increasing demand A recommendation must be given to the management board based on these business requirements
1. Seamless Scalability: The solution should be able to work at scale to handle the growing number of customers and data traffic without compromising performance.
2. High Availability: The network must provide a high level of availability and redundancy to minimize downtime and data loss.
3. Data Security: Strong security measures must be implemented to safeguard sensitive financial information and protect against cyber threats. At any given time, the placement of data must be known, and additionally, data must be stored within the customer ' s own region.
4. Cost effectiveness: The proposed solution must be economically viable, adhering to any budget constraints, which currently prohibits CapEx spending, but just recently, new edge routers were added to the data centers, so it is safe to assume they can support any of the options.
Which recommendation can be given?

• A. Propose a hybrid approach where the company retains critical data and applications on-premises and utilizes the cloud for additional computing resources during peak periods.
• B. Recommend upgrading the existing on-premises network infrastructure by adding more servers, storage, and networking equipment to meet the increased demand.
• C. Advise building a private cloud infrastructure within the company ' s data centers to ensure more control over data and compliance requirements.
• D. Suggest migrating all business-critical operations and data to a public cloud platform, leveraging the cloud provider ' s infrastructure and services.

Refer to the exhibit A company has a hybrid cloud architecture with two on-premises data centers that connect to a public cloud service provider by using direct connect and eBGP routing. Encryption is unsupported by the cloud service provider, so the company plans to use an IPsec overlay network over its direct connects. Two virtual network appliances will be installed in the cloud infrastructure to establish tunnels and perform routing The company chose OSPF as the overlay routing protocol because the operations team is familiar with the protocol and because OSPF is the IGP on the on-premises network. The cloud network must be as isolated as possible from the on-premises network. What must be used for the OSPF overlay connectivity ?

• A. different OSPF instance. NVA as the ASBR
• B. different OSPF area. NVA as the ABR
• C. different OSPF area. Cloud Edge as the ABR
• D. different OSPF instance. Cloud Edge as the ASBR
