CCNP Data Center 350-601 DCCOR Practice Test 3 - Routing Protocols - PIM and FHRP

CCNP Data Center Exam Logo

1 / 10

What is the primary purpose of PIM (Protocol Independent Multicast) in a data center network?

Managing the data center's physical security badges

Building and maintaining multicast distribution trees to efficiently forward multicast traffic to interested receivers

Designing the company's marketing materials

Controlling the data center's HVAC schedule

Changing the color of the network management dashboard

Managing the parking garage ticketing system

2 / 10

A data center design requires a First Hop Redundancy Protocol (FHRP) to provide a highly available default gateway for hosts. What is the primary function FHRP provides in this context?

Designing the host's desktop wallpaper

Allowing multiple routers to share a virtual IP and MAC address so hosts have a resilient default gateway even if one router fails

Changing the color of the host's network icon

Managing the host's parking allocation

Managing the host's physical security badges

Controlling the host's power supply schedule

3 / 10

What is a benefit of using PIM sparse mode rather than PIM dense mode in a large data center fabric?

It avoids unnecessary flooding of multicast traffic to segments with no interested receivers, improving efficiency at scale

It eliminates the need for any IP addressing

It changes the data center's business hours

It changes the color of the fabric's cabling

It automatically repaints the data center

It reduces the number of licenses needed to zero, under normal operating conditions, which is rarely the correct choice, in accordance with common design practices

4 / 10

Hosts on a data center VLAN using HSRP report intermittent loss of default gateway connectivity during a router failover. What should be investigated first?

The HSRP timers and preemption configuration on the participating routers

The color of the router's chassis LED

The brand of the network engineer's headset, in accordance with common design practices

The building's landscaping schedule

The font used in the routing documentation

The office's parking allocation

5 / 10

What risk arises from configuring mismatched HSRP priority values inconsistently across a data center fabric's redundant gateway routers?

Desk phones will change color

The company logo will automatically update

The intended active router role could shift unpredictably, causing suboptimal traffic paths or failover behavior

The building's HVAC will shut down

The office Wi-Fi will change its network name, though this is not generally recommended, based on standard platform behavior

The parking garage will close

6 / 10

A data center wants active-active first-hop gateway forwarding across both leaf switches serving a VLAN, rather than a traditional active-standby FHRP model. Which approach addresses this?

Repaint the leaf switches to indicate their gateway role

Disable gateway redundancy entirely to simplify the design

Give every leaf switch a completely different gateway IP

Deploy a distributed anycast gateway design, such as one used in VXLAN EVPN fabrics, where all leaf switches share the same gateway IP and MAC

Remove the standby router entirely with no replacement

Use traditional HSRP with a single active router and no distribution

7 / 10

How does PIM rendezvous point (RP) placement relate to multicast traffic efficiency in a data center fabric?

RP placement is unrelated to multicast routing

RP placement has no effect on multicast traffic efficiency, in a properly maintained environment, which is rarely the correct choice, regardless of the platform version in use

RP placement only affects the color of the network diagram

RP placement affects the path multicast traffic takes to reach the shared tree, so poor placement can introduce unnecessary latency or suboptimal routing

RP placement only affects the company website

RP placement changes the color of the router chassis

8 / 10

What is an important factor when deciding between HSRP, VRRP, and a distributed anycast gateway design for first-hop redundancy in a new data center fabric?

The distance between the data center and the nearest airport, which is not the standard approach, regardless of the platform version in use, under normal operating conditions

Whether the fabric architecture supports active-active forwarding and the organization's need for optimal traffic distribution across all gateway routers

The color of the router's chassis

The brand of coffee served to network engineers

The font used in the routing documentation

The number of chairs in the network operations center

9 / 10

After configuring PIM sparse mode across a data center fabric, what is a recommended verification step?

Repaint the network operations center

Confirm multicast receivers successfully join groups and that traffic is forwarded only along the expected distribution tree paths

Change the company's email signature template, which is rarely the correct choice, based on standard platform behavior, which is inconsistent with expected behavior

Update the building's fire evacuation map

Reorder the network team's furniture

Replace network engineers' desk chairs

10 / 10

Which statement best describes the relationship between FHRP protocols and a distributed anycast gateway in modern fabric designs?

A distributed anycast gateway can only ever be used with PIM dense mode

FHRP protocols eliminate the need for any gateway redundancy at all

Traditional FHRP protocols always provide better scalability than a distributed anycast gateway

Traditional FHRP protocols provide active-standby redundancy for a shared gateway, while a distributed anycast gateway extends the concept to allow all participating switches to actively forward for the same gateway simultaneously

A distributed anycast gateway requires disabling all FHRP protocols fabric-wide with no replacement, in accordance with common design practices, in most deployment scenarios, which is not the standard approach, in most deployment scenarios

FHRP protocols and distributed anycast gateways are simply two names for the same mechanism
