Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q17-Q22):

NEW QUESTION # 17
Refer to the exhibit.

There are multiple trees in the Cisco FabricPath All switches in the Layer 2 fabric share the same view of each tree. Which two concepts describe how the multicast traffic is load-balanced across this topology?
(Choose two )

Answer: D,E


NEW QUESTION # 18
An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A.
providing Layer 2 connectivity between a central site and approximately 100 remote sites. Customer A wants to use the VPLS network to carry its internal multicast video feeds which are sourced at the central site and consist of 20 groups at Mbps each. Which service provider recommendation offers the most scalability?

Answer: C


NEW QUESTION # 19
Company XYZ Is running a redundant private WAN network using OSPF as the underlay protocol.
The current design accommodates for redundancy. In the network, but it Is taking over 30 seconds for the network to reconverge upon failure.
Which technique can be Implemented In the design to detect such a failure in a subsecond?

Answer: E


NEW QUESTION # 20
Refer to the exhibit.

The WAN network of the General Bank of Greece has experienced several outages. It takes too long to activate a new branch site. The networking department of the bank plans to upgrade the legacy end-of-life WAN network with a new flexible, manageable, and scalable in-house solution. The number of branches will increase exponentially in the next fiscal year. The CTO states that the bank's main goal is OPEX reduction.
The network engineering team prepares a table to evaluate the available options. Which WAN technology can be used for the solution?

Answer: C

Explanation:
The scenario prioritizes:
* In-house management (not managed services)
* Scalability (exponential branch growth)
* OPEX reduction (low operational cost)
SD-WAN over L3VPN offers a balance of:
* Mid-level ISP cost (leveraging L3VPN as transport)
* Centralized management and automation (ZTP, templates)
* Support for segmentation, application-aware routing, and path control
* Lower OPEX due to simplified configuration and monitoring
Managed SD-WAN has higher ISP and OPEX cost, and DMVPN is more manual and complex to scale. SD- WAN over L2VPN might reduce ISP cost but is less common and not optimal for rapid scalability.


NEW QUESTION # 21
Many companies are turning to a hybrid cloud strategy to drive innovation and improve their in- house digital transformation projects. Creating a comprehensive plan for cloud migration can be challenging because there are many factors to consider.
Which feature ensures that cloud networks talk to each other instead of existing in silos, working together to achieve an intended outcome?

Answer: D

Explanation:
Interoperability ensures that different cloud networks can communicate and operate together rather than existing in silos. This is essential in a hybrid cloud strategy to integrate services and achieve intended business outcomes.
