NEW QUESTION # 377
Refer to the exhibit.
As part of a redesign project, you must predict multicast behavior What happens to the multicast traffic received on the shared tree (*,G), if it is received on the LHR interface indicated*?
Answer: D
NEW QUESTION # 378
Which three tools are used for ongoing monitoring and maintenance of a voice and video environment?
(Choose three.)
Answer: A,C,E
Explanation:
* A: Flow-based analysis allows understanding bandwidth usage across apps and sessions, crucial for voice/video capacity management.
* C: Call management systems track CAC and call quality failures, key for voice/video troubleshooting.
* D: Active synthetic probes proactively inject traffic to monitor loss, latency, and jitter under real-time conditions.
Why other options are incorrect:
* B: Network convergence is not directly analyzed through call management tools.
* E: Passive synthetic probes is not an accurate term; passive monitoring refers to analysis of real traffic flows, not synthetic tests.
* F: PTP time-stamping is more applicable to clock synchronization, not regular voice/video performance monitoring.
NEW QUESTION # 379
A business requirement is supplied to an architect from a car manufacturer stating their business model is changing to just-in-time manufacturing and a new network is required. The manufacturer does not produce all of the specific components in-house. Which area should the architect focus on initially?
Answer: D
Explanation:
Just-in-time (JIT) manufacturing relies on precision timing and real-time data exchanges between production systems and external suppliers. Network latency can directly impact the efficiency and viability of such a system. For this reason, the architect must prioritize a network design that ensures minimal delay and rapid delivery of application and sensor data.
According to CCDE v3.1 design principles, when latency is tied directly to business outcomes (e.g., manufacturing workflow dependencies), the network must be designed with a focus on:
* End-to-end low-latency infrastructure
* Predictable jitter and delay control
* Application prioritization mechanisms (QoS)
* High availability and redundancy
This allows the manufacturer to optimize production throughput while reducing delays caused by communication lag with external component providers.
Why other options are incorrect:
* A. Automation helps with operational efficiency, but it does not directly ensure low-latency communication.
* B. Zero Trust is a security model, not latency-related.
* D. Modularity is about design structure, not latency performance.
NEW QUESTION # 380
A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS Traffic Engineering Fast Reroute solution has the same failover/failback times as a traditional SONET/SDH network (around 50 msec). In order to address both link failure and node failure within the lab topology network, which type of the MPLS TE tunnels must be considered for this demonstration?
Answer: A
Explanation:
To achieve sub-50ms protection against both link and node failures, MPLS TE Fast Reroute (FRR) with Next- Next-Hop (NNHop) protection is used:
* Next-Next-Hop tunnels provide node protection by pre-establishing a detour that bypasses not only the immediate next-hop link but also the entire next node.
* This ensures protection for both link and node failures, matching SONET/SDH resiliency targets.
Other options explained:
* A & C: TE backup and FRR backup tunnels may only provide link protection depending on deployment.
* B: Next-Hop tunnels address only link failures, not node failures.
