Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q537-Q542):

NEW QUESTION # 537
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: B

Explanation:
* BFD (Bidirectional Forwarding Detection) provides rapid failure detection independent of OSPF's native hello/dead timers.
* BFD operates at subsecond intervals (as low as 50ms), detecting link failures almost immediately, allowing OSPF to react instantly upon failure detection.
* BFD complements OSPF and significantly improves convergence time without compromising OSPF's stability.
Why other options are incorrect:
* A: STP is irrelevant for Layer 3 routing failures.
* B: Fate sharing describes failure domains, not detection mechanisms.
* C: OSPF LFA provides fast reroute after failure detection but doesn't accelerate detection itself.
* E: Flex links are used in Layer 2 switching, not for OSPF-based WAN failover.


NEW QUESTION # 538
Company XYZ is designing the IS-IS deployment strategy for their multiarea IS-IS domain. They want IS-IS neighbor relationships minimized on each segment and the LSDB size optimized. Which design can be used?

Answer: B

Explanation:
* D (L1/L2 for ABRs and L1 for internal routers):This hierarchical approach minimizes LSDB size inside areas (L1 routers only maintain intra-area routes) while L1/L2 routers handle inter-area route propagation, reducing neighbor adjacencies and improving scalability.
Other options explained:
* A: Level 2 everywhere results in larger LSDBs across all routers.
* B: Only L2 routers at ABRs would isolate L1 domains improperly.
* C: Pure L1 design prevents inter-area reachability.


NEW QUESTION # 539
A European government passport agency considers upgrading its IT systems to increase performance and workload flexibility in response to constantly changing requirements. The budget manager wants to reduce capital expenses and IT staff and must adopt the lowest-cost technology. Which technology choice is suitable?

Answer: A

Explanation:
* Public cloud offers scalability, flexibility, and consumption-based pricing, which directly reduces capital expenditures (CAPEX) and minimizes operational burden (less IT staff needed for infrastructure maintenance).
* Public cloud eliminates upfront hardware investments and shifts cost to predictable operational expenses.
* Public cloud providers handle hardware maintenance, upgrades, and scalability, making it highly cost- effective for government agencies with fluctuating workloads.
Why other options are incorrect:
* A: On-premises increases CAPEX and requires significant IT staff.
* B: Private cloud reduces some OpEx but still requires infrastructure management and higher CAPEX.
* D: Hybrid cloud increases complexity and operational costs.

Answer: B,D


NEW QUESTION # 541
Scrum is a subset of Agile and is a lightweight process framework for Agile development Which role becomes the interface between the business the customers and their product-related needs on one side and the Team on the other?

Answer: B

Explanation:
# Explanation:
* A: The Product Owner is responsible for defining user stories, maintaining the product backlog, and representing the customer's voice to the development team.
* B: Product Manager may define broader strategy but doesn't manage the backlog directly.
* C: Scrum Master ensures the process is followed but doesn't interface with the business side.
* D: Program Manager oversees multiple projects; not Scrum-specific.
