The goal is to have product specialists available via video link when customers visit the nationwide branch offices Which technology should be used to meet this objective?

In traditional network design, the network and data center are confined within a single building In this configuration, a router connects the internal and external networks Basic configuration of an access control list within the router controls the traffic that can pass through Which security technique defines the boundary between an internal/trusted network and an external/untrusted network?

A global e-commerce company is expanding its operations and planning to migrate its entire infrastructure to a hybrid cloud solution. They are concerned about data governance and want to ensure that their customers ' data is treated with utmost respect to sovereignty and privacy. What is an appropriate approach?

SDN controllers need to sustain healthy operation under the pressure of different objectives from the applications they host. High availability can be achieved through improved southbound APIs and controller placement heuristics and formal models. Which two implementation strategy help to maximize resilience and scalability? (Choose two.)

A networking team needs to prevent spoofing attacks They are describing the different uRPF design use cases so they can identify and deploy the optimal mode in various parts of their network

Drag and drop the use cases from the left onto the corresponding uRPF technique on the right Not all options are used

A multinational enterprise integrates a cloud solution with these objectives

Achieve seamless connectivity across different countries and regions

Extend data center and private clouds into public clouds and provider-hosted clouds

What are two outcomes of deploying data centers and fabrics that interconnect different cloud networks? (Choose two)

Two companies need to implement an extranet overlay network solution by using a VPN tunnel over the internet to use each other ' s HTTP REST APIs. The solution must only provide data integrity because data confidentiality will be covered at the application layer The existing firewall devices will be used as VPN endpoints for the tunnel but they have limited available resources Which type of VPN tunnel must be deployed for the extranet service?

Compared to data plane traffic, control plane traffic is relatively small in volume, but these flows are critical to the overall functioning of the network infrastructure and to voice and video endpoint well. When designing a QoS policy for a network, which two actions for the network control service-class is recommended? (Choose two)

A business wants to centralize servies via VDI technology and to replace remote WAN desktop PCs with thin client-type machines to reduce operating costs Which consideration supports the new business requirement?

A consultant needs to explain different project management methodologies to a customer.

SD-WAN can be used to provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud over any type of IP-based underlay transport network. Which two statements describe SD WAN solutions? (Choose two.)

Reter to the exhibit This network is running OSPF and EIGRP as the routing protocols Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs The OSPF network must be designed so that flapping routes m EIGRP domains do not affect the SPF runs within OSPF The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains Which technique accomplishes the requirement?

Refer to the exhibit. A customer needs to implement a connectivity model by using one active link for inbound and outbound traffic and a second link for backup. The backup link is low speed and is required only during outages of the primary link. Which design solution should be implemented?

Company XYZ wants to improve the security design of their network to include protection from reconnaissance and DoS attacks on their sub interfaces destined toward next hop routers. Which technology can be used to prevent these types of attacks?

monitoring solution, an organization wants to ensure they can collect feedback from network devices, particularly with a focus on being able to perform anomaly detection and automatically react to these events as they come m A key requirement is that the resources required to collect the data must be distributed Which data reporting approach is good fit for this use case?

The advantages of a hybrid SDN/OSPF control plane are broadly recognized in the networking community, as it promises the best of two worlds: programmability and agility of SDN and the reliability and fault tolerance of OSPF, but there are tradeoffs. Which two challenges of a hybrid SDN control plane exist in an operational network? (Choose two.)
