NEW QUESTION # 185
A consultant needs to evaluate project management methodologies for a new service deployment on the existing network of a customer. The customer wants to be involved in the end-to-end project progress and be provided with frequent updates. The customer also wants the ability to change the requirements if needed, as the project progresses. Which project management methodology should be used?
Answer: D
Explanation:
Agile project management supports:
* Frequent updates and iterative feedback loops
* Flexibility to accommodate evolving requirements
* Continuous customer collaboration and transparency
This methodology is ideal for projects where scope may shift and customer involvement is essential. In contrast:
* Waterfall is linear and rigid
* Phased delivery segments milestones but limits change midstream
* "Three principles" is not a recognized methodology in this context
Agile aligns with modern IT deployment models and is supported in CCDE methodology as a business- aligned and adaptive design execution strategy.
NEW QUESTION # 186
synchronizing data between host A and host B. To increase chance of delivery the same data is sent twice from host A on two different NICs toward the two NICs on host B.
Refer to the exhibit. All links are P2P Layer 3. A high availability application is synchronizing data between Host A and Host B. To increase the chance of delivery, the same data is sent twice from Host A on two different NICs toward the two NICs on Host B.
Which solution must be deployed in the network to ensure that any failure in the network does not trigger data loss on Host B?
Answer: A
Explanation:
In this scenario, the application itself duplicates data transmission across two separate NICs on Host A, with the intention that at least one copy will reach Host B, regardless of any single path or link failure. While this increases redundancy at the application and host level, the underlying network must also support rapid failure recovery to avoid packet loss during convergence events.
Among the options provided:
A). EIGRP with feasible successors provides pre-computed backup routes but still requires routing protocol convergence upon failure, which could result in millisecond-scale interruption-enough to cause data loss if packets are in transit.
B). BFD (Bidirectional Forwarding Detection) offers rapid detection of link failures, but by itself does not provide traffic redirection or packet protection; it simply informs the routing protocol faster.
D). Static routes lack dynamic convergence capabilities and would not offer high availability across dynamic failure points unless manually configured with tracking-still less responsive and scalable.
C). IP Fast Reroute (IP FRR) is specifically designed to offer sub-50ms convergence time by pre-installing backup paths in the forwarding plane. Upon detecting a failure, traffic is immediately switched to the pre- computed alternate path without waiting for the routing protocol to reconverge. This ensures minimal disruption and best supports lossless delivery for high-availability applications.
IP FRR is consistent with CCDE v3.1 design principles where sub-second convergence and resiliency are critical in mission-critical enterprise and data center architectures.
NEW QUESTION # 187
During IPv6 deployment in a legacy network, what must be considered for older Layer 2 switches? (Choose two)
Answer: A,D
Explanation:
#Explanation:
* C: IPv6 functions at Layer 3, and Layer 2 switches (which do not inspect or modify Layer 3 headers) typically forward IPv6 frames transparently just like IPv4-unless enhanced services are needed.
* D: For efficient IPv6 multicast handling (e.g., neighbor discovery, multicast services), switches should support MLD snooping (equivalent to IGMP snooping for IPv4).
Incorrect options:
* A, B, E: DHCPv6 snooping, ND snooping, and ICMPv6 snooping are not standard or widely implemented features in Layer 2 devices. They're also unnecessary for basic IPv6 forwarding.
