A financial services company needs to interconnect two data centers for synchronous replication of a database. The replication traffic is sensitive to latency and jitter. The company has a dedicated fiber link between the sites. Which interconnect type is most appropriate for this requirement?

IP-based interconnect over the public internet

Direct dark fiber with Ethernet or optical transport

VXLAN-based interconnect over a shared IP network

MPLS-based interconnect over a service provider network

A service provider offers DCI services to multiple customers. They need to provide each customer with isolated Layer 2 connectivity between their data centers. The provider's backbone is MPLS-enabled and they want to use a single technology that supports multi-tenancy and efficient MAC learning. Which technology should they use?

IP-based interconnect with GRE tunnels

VPLS with per-customer pseudowires

A network engineer is designing a DCI solution to extend Layer 2 between two data centers over an IP backbone. They want to avoid the use of multicast in the underlay and prefer a control plane that learns MAC addresses efficiently. Which solution should they implement?

VXLAN with head-end replication

What is a key benefit of EVPN-based interconnects?

They provide both Layer 2 and Layer 3 interconnectivity across data centers

They require a full mesh of physical connections

They eliminate the need for any routing protocol

They are limited to Layer 2 only

What is the primary role of VXLAN in a data center interconnect?

To replace IP routing between data centers

To extend Layer 2 networks over Layer 3 infrastructure

To provide traffic engineering capabilities

To replace MPLS in service provider networks

Part of the Data Center Interconnect domain, which makes up ~20% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 1–2 from this objective — we provide 30 practice questions to prepare you well beyond it.
