NEW QUESTION # 174
With SDN, network administrators can automate many tasks, such as configuring network policies, traffic flows, and security settings. This automation can significantly reduce the time and effort required to manage and maintain networks.
Which focus area of task automation can the network engineers use to greatly reduce manual effort for everyday network changes?
Answer: A
Explanation:
End-to-end outcome automation focuses on automating entire workflows rather than individual tasks, which greatly reduces manual effort and ensures consistency in everyday network changes.
NEW QUESTION # 175
An architect receives a business requirement from a CTO that states the RTO and RPO for a new system should be as close as possible to zero. Which replication method and data center technology should be used?
Answer: A
Explanation:
* C (Synchronous replication over Metro Ethernet) provides real-time replication with zero data loss (RPO = 0) and minimal recovery time (RTO # 0).
* Metro Ethernet offers low-latency, high-bandwidth, and deterministic connectivity between closely located data centers, ideal for synchronous replication.
Why other options are incorrect:
* A & D: Asynchronous replication cannot guarantee zero RPO/RTO.
* B: MPLS introduces variable latency unsuitable for synchronous replication.

NEW QUESTION # 176
A Tier-3 Service Provider is evolving into a Tier-2 Service Provider due to the amount of Enterprise business it is receiving. The network engineers are re-evaluating their IP/MPLS design considerations in order to support duplicate/overlapping IP addressing from their Enterprise customers within each Layer3 VPN. Which concept would need to be reviewed to ensure stability in their network?
Answer: A
Explanation:
Route Distinguishers (RDs) are fundamental to MPLS Layer 3 VPN architecture (RFC 4364). They allow the service provider to distinguish identical IP prefixes from different VPN customers by adding a unique identifier to each VPN route, preventing conflicts from overlapping IP spaces.
* Unique RDs ensure that the VPNv4 address family maintains separation of identical customer prefixes.
Why other options are incorrect:
* B: Route Targets control route import/export policy but do not differentiate overlapping prefixes.
* C: NAT is not required inside MPLS VPN for overlapping IPs.
* D: VRF IDs are local identifiers on routers; not relevant for prefix uniqueness in control plane.
