A network architect in an enterprise is designing a network policy for certain database applications. The goal of the policy is to allow these applications to access the internet directly, whereas other user and network applications that communicate with systems or users outside their own network must be routed through the data center. The focus is on achieving higher availability and a better user experience for the database applications, but switching between different network paths based on performance characteristics must be supported.Which solution meets these requirements?
Answer(s): B
Cloud onRamp for IaaS (C) is a solution that focuses on providing secure and optimized connectivity to Infrastructure-as-a-Service (IaaS) environments. While it may provide some benefits for network connectivity, it does not directly address the requirement of allowing direct internet access for specific database applications.

When an SDN-based model is used to transmit multimedia traffic, which aspect should an architect consider while designing the network?
QoE (Quality of Experience) is a measure of how well a user experiences a multimedia application. It is important to consider QoE when designing an SDN-based network for multimedia traffic, as it can impact the user's experience.The other options are also important considerations, but they are not as critical as QoE.-Security: Security is important for all networks, but it is especially important for networks that transmit multimedia traffic. This is because multimedia traffic can be more easily intercepted and manipulated than other types of traffic.-Traffic patterns: Traffic patterns can impact the performance of an SDN-based network. For example, if the network is used to transmit a lot of real-time traffic, then it is important to ensure that the network can handle the traffic spikes that can occur with real-time traffic.-Flow forwarding: Flow forwarding is the process of routing packets through the network. It is important to consider flow forwarding when designing an SDN-based network, as it can impact the performance of the network.
A customer has a functional requirement that states HR systems within a data center should be segmented from other systems that reside in the same data center and same VLAN. The systems run legacy applications by using hard-coded IP addresses with all HR systems dedicated to .129 to .254 of the 10.20.20.0/24 prefix. Which segmentation method is optimal for the customer?
Answer(s): C
VACLs (Virtual Access Control Lists) are a type of ACL that can be used to segment traffic within a data center. VACLs are configured on the switches in the data center, and they can be used to restrict traffic between different VLANs.In this case, the customer has a requirement to segment HR systems from other systems in the same data center and VLAN. VACLs can be used to achieve this by creating a VACL that allows traffic between the HR systems and the rest of the network.The other options are not as optimal for this scenario.-Data center perimeter firewalling: Data center perimeter firewalling is used to protect the data center from external threats. It would not be effective for segmenting traffic within the data center.-Routed firewalls: Routed firewalls are used to route traffic between different networks. They would not be effective for segmenting traffic within a single VLAN.-ACLs on data center switches: ACLs are a type of firewall that can be used to restrict traffic on a network. However, they are not as granular as VACLs, and they can be more difficult to manage.
Refer to the exhibit. An architect must design an enterprise WAN that connects the headquarters with 22 branch offices. The number of remote sites is expected to triple in the next three years. The final solution must comply with these requirements:•Only the loopback address of each of the enterprise CE X and Y routers must be advertised to the interconnecting service provider cloud network.•The transport layer must carry the VPNv4 label and VPN payload over the MP-BGP control plane.•The transport layer must not be under service provider control.Which enterprise WAN transport virtualization technique meets the requirements?
