Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q143-Q148):

NEW QUESTION # 143
Implementing a network automation architecture usually follows a phased approach that increases automation as the new technology and processes in the preceding phases are integrated and adopted. What provides a model that greatly simplifies the interaction with network devices?

Answer: A


NEW QUESTION # 144
Refer to the table.

A customer investigates connectivity options for a DCI between two production data centers to aid a large-scale migration project. The migration is estimated to take 20 months to complete but might extend an additional 10 months if issues arise. All connectivity options meet the requirements to migrate workloads.
Which transport technology provides the best ROI based on cost and flexibility?

Answer: A


NEW QUESTION # 145
If the desire is to connect virtual network functions together to accommodate different types of network service connectivity what must be deployed?

Answer: E

Explanation:
Service chaining is the technique of connecting virtual network functions together to provide different types of network service connectivity. Service chaining uses software-defined networking (SDN) programmability to create a chain of connected network services, such as firewalls, load balancers, NAT, and intrusion protection. Service chaining can automate the provisioning of network applications that have different characteristics and requirements, such as security, latency, or quality of service (QoS). Service chaining can also optimize the use of network resources and improve application performance by using SDN analytics and performance tools to select the best available network paths and avoid network congestion. Service chaining is being used in many SDN and network functions virtualization (NFV) use cases and deployments, such as data centers, carrier networks, and virtual customer edge123. Reference:

2: On service chaining using Virtual Network Functions in Network-enabled Cloud systems | IEEE Conference Publication | IEEE Xplore
3: Service function chaining - Gini5


NEW QUESTION # 146
An enterprise wants to provide low-cost delivery of network systems that can be scaled on business demand, followed by an initiative to reduce capital expenses for new IT equipment.
Which technology meets these goals?

Answer: D


NEW QUESTION # 147
In an SDN architecture, what is present on the switches but not on the centralized controller?

Answer: B

Explanation:
# Explanation:
C: In SDN, switches retain the data plane functionality-they forward packets based on flow rules received from the controller.
A: Control plane functions are moved to the centralized controller in SDN.
B: Southbound interfaces are present on both controllers and switches for communication.
D: Northbound interfaces exist on controllers to interact with applications-not switches.
