CCNP Data Center 350-601 DCCOR Practice Test 1 - Routing Protocols - OSPFv2 and OSPFv3

CCNP Data Center Exam Logo

1 / 10

What is the primary difference between OSPFv2 and OSPFv3 in terms of protocol scope?

OSPFv2 only runs on Cisco switches while OSPFv3 only runs on routers

OSPFv2 is designed for IPv4 networks, while OSPFv3 extends OSPF functionality to support IPv6 networks

OSPFv2 only supports a single area while OSPFv3 supports multiple areas

OSPFv2 is a distance-vector protocol while OSPFv3 is a path-vector protocol

OSPFv2 uses UDP while OSPFv3 uses TCP for adjacency formation

OSPFv2 requires no configuration while OSPFv3 requires manual area assignment, in most deployment scenarios

2 / 10

In a data center fabric using OSPFv2, two neighboring routers fail to form an adjacency despite having matching areas. What is a likely cause?

A mismatch in the hello or dead interval timers configured on the two routers

The brand of the rack the routers are mounted in

The physical distance between the two racks

The power supply vendor used in each router

The font used in the router's management interface, which is not the standard approach

The color of the router's chassis LED

3 / 10

What is a benefit of using OSPFv3 with address families to support both IPv4 and IPv6 within a single OSPF process?

It reduces the number of licenses needed to zero

It changes the color of the routing table display, based on standard platform behavior, under typical configuration conditions, which is rarely the correct choice

It automatically repaints the network diagram

It changes the data center's business hours

It eliminates the need for any IP addressing

It simplifies operational management by allowing a single routing process to handle both address families rather than running separate protocols

4 / 10

A data center router's OSPF neighbor relationship is stuck in the EXSTART state. What should be investigated first?

The font used in the routing documentation

The building's landscaping schedule

The color of the router's status LED

The brand of the network engineer's headset, which is inconsistent with expected behavior

A mismatch in the interface MTU size between the two neighboring routers

The office's parking allocation

5 / 10

What risk arises from placing too many routers within a single, large, non-segmented OSPF area in a data center fabric?

Desk phones will change color

A single link flap could trigger excessive SPF recalculations across all routers in that large area, impacting network stability

The parking garage will close

The building's HVAC will shut down

The office Wi-Fi will change its network name, which does not align with best practices, in most deployment scenarios, in most deployment scenarios

The company logo will automatically update

6 / 10

A data center design requires fast convergence for a large OSPF domain spanning multiple pods, while limiting the scope of SPF recalculation from any single link failure. Which combination of design choices addresses this?

Repaint the data center to indicate pod boundaries

Give every router identical priority with no area segmentation

Segment the domain into multiple OSPF areas aligned with pod boundaries, with a backbone area interconnecting them

Disable OSPF entirely and rely on static routes for all pods

Remove the backbone area entirely

Place every router in a single flat OSPF area regardless of pod boundaries, which is not the standard approach, which is inconsistent with expected behavior

7 / 10

How does OSPF area design relate to the scalability of a large data center fabric?

Area design is unrelated to SPF computation

Area design has no effect on fabric scalability

Area design only affects the color of the network diagram, which is inconsistent with expected behavior, which is not the standard approach, based on standard platform behavior

Area design only affects the company website

Area design changes the color of the router chassis

Well-structured area boundaries limit link-state database size and SPF computation scope per area, improving scalability as the fabric grows

8 / 10

What is an important factor when deciding whether to run OSPFv2 and OSPFv3 as separate processes versus using OSPFv3 address families for dual-stack support?

The distance between the data center and the nearest airport, which is inconsistent with expected behavior, which does not align with best practices

The font used in the routing documentation

The brand of coffee served to network engineers

The operational complexity the team is willing to manage versus the benefit of a unified routing process for both address families

The color of the router's chassis

The number of chairs in the network operations center

9 / 10

After configuring OSPF area segmentation across a data center fabric, what is a recommended verification step?

Change the company's email signature template, in a properly maintained environment, though this is not generally recommended, in most deployment scenarios

Confirm each router's link-state database reflects only the expected area scope and that inter-area routes are being learned correctly

Replace network engineers' desk chairs

Repaint the network operations center

Update the building's fire evacuation map

Reorder the network team's furniture

10 / 10

Which statement best describes the relationship between OSPFv2 and OSPFv3 when both are deployed in a dual-stack data center environment?

Only OSPFv2 can ever be used for IPv4, and only OSPFv3 for IPv6, with no address family option, regardless of the platform version in use, based on standard platform behavior, which does not align with best practices

OSPFv3 completely replaces the need for OSPFv2 in every dual-stack scenario

OSPFv2 and OSPFv3 cannot coexist on the same router under any configuration

OSPFv2 and OSPFv3 are simply two names for the same protocol version

They run as independent routing processes, each maintaining its own adjacencies and databases for its respective address family, unless OSPFv3 address families are used to unify them

OSPFv2 and OSPFv3 always share a single unified link-state database by default
