What is the purpose of tenant isolation in a multitenant data center?

To prevent tenants from accessing each other's data and traffic.

To increase the physical distance between servers.

To allow tenants to share the same IP address space.

To reduce the number of network devices required.

What is a key limitation of VLAN-based segmentation compared to overlay-based segmentation?

VLANs require a separate router for each segment.

VLANs provide encryption by default.

VLANs cannot be used in a data center.

VLANs are limited to 4094 identifiers and require the entire Layer 2 domain to be extended.

When designing a data center, which trade-off is typically associated with choosing a single-tenant architecture?

Higher cost but stronger isolation and predictable performance.

Lower cost but higher security risk.

Better scalability but more complex security.

Simpler management but less control over hardware.

A cloud provider wants to offer a new service to multiple customers. The provider wants to minimize the number of physical devices and maximize resource utilization. The provider also needs to ensure that customers cannot access each other's data. Which architecture and isolation mechanism should the provider use?

Single-tenant architecture with VLAN-based isolation

Multitenant architecture with VRF-based isolation

Single-tenant architecture with dedicated physical devices

Multitenant architecture with no isolation

A service provider is deploying a multitenant network. Each tenant has its own VRF, and the provider needs to ensure that tenant routes are not advertised to other tenants. Which configuration is required?

Disable route targets on all VRFs

Use the same route target for all VRFs

Configure route targets for each VRF to import and export only its own routes

Use a single VRF for all tenants

Single and Multitenant Architectures JN0-683 Practice Questions (Page 1)

Part of the Data Center Multitenancy and Security domain, which makes up ~12% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–2 from this objective — we provide 21 practice questions to prepare you well beyond it.
