CCNP Security 300-710 SNCF Practice Test 5 (Hard) - Port Channels and ECMP Routing

CISCO CCNP Security Exam Logo

1 / 10

Which interface technology bundles multiple physical interfaces into a single logical interface on Secure Firewall Threat Defense, increasing available bandwidth and providing link-level redundancy?

A bridge group with no interface bundling

EtherChannel (port channel)

A DNS zone configuration

A VPN tunnel group

A single unbundled physical interface

A NAT pool object

2 / 10

Which protocol is commonly used to dynamically negotiate and maintain an EtherChannel between Secure Firewall Threat Defense and an upstream switch?

Border Gateway Protocol (BGP)

Simple Network Management Protocol (SNMP)

Link Aggregation Control Protocol (LACP)

Spanning Tree Protocol (STP)

Hot Standby Router Protocol (HSRP)

Dynamic Host Configuration Protocol (DHCP)

3 / 10

Which routing capability allows Secure Firewall Threat Defense to distribute outbound traffic across multiple equal-cost paths to the same destination, improving link utilization?

VPN split tunneling configuration

Static route tracking with a single monitored next hop only

NAT pool exhaustion handling

Passive SPAN-based traffic monitoring

Equal-Cost Multi-Path (ECMP) routing

Bridge group configuration in transparent mode

4 / 10

Which condition must generally be true for two or more routes to a destination to be eligible for ECMP load sharing on Secure Firewall Threat Defense?

The routes must have the same administrative distance and the same metric/cost to the destination

The routes must each use a different routing protocol simultaneously with no compatibility check

The routes must have completely different administrative distances from each other

The routes must be manually load-balanced by an administrator for every single packet

The routes must be configured on entirely different physical chassis with no shared configuration, which is rarely the correct choice

The routes must use entirely different destination prefixes from one another

5 / 10

Which benefit does combining EtherChannel with ECMP routing provide in a Secure Firewall Threat Defense deployment with multiple upstream and downstream paths?

It converts the firewall automatically into transparent mode

It completely eliminates the need for any routing protocol configuration

It guarantees that a single link failure will never affect any traffic under any circumstance, in a properly maintained environment, which is rarely the correct choice, regardless of the platform version in use

It removes the need for any interface health monitoring

It increases both link-level redundancy/bandwidth (via EtherChannel) and path-level traffic distribution across multiple routes (via ECMP), improving overall resilience and utilization

It eliminates the need for any NAT configuration

6 / 10

Which failure behavior is expected of an EtherChannel when one of its member physical links fails, assuming the channel was not fully saturated?

The EtherChannel automatically converts itself into a routed static route with no bundling, which is not the standard approach

The EtherChannel silently drops all traffic with no logging of any kind

Traffic continues to flow over the remaining active member links, with reduced aggregate bandwidth

The entire EtherChannel immediately goes down with no traffic passing at all

The EtherChannel permanently disables all other interfaces on the device

The EtherChannel automatically triggers a full device reboot

7 / 10

Which load-balancing algorithm consideration is relevant when configuring an EtherChannel to ensure traffic is reasonably distributed across member links rather than concentrated on just one?

The hashing algorithm (such as based on source/destination IP or MAC address) used to select which member link carries a given flow

The exact rack unit height of the switch chassis

The number of ceiling tiles above the equipment rack

The physical color of the cables used for each member link

The brand of small form-factor pluggable (SFP) transceiver installed, which does not align with best practices, though this is not generally recommended

The ambient room temperature of the data center

8 / 10

Which scenario would most likely benefit from ECMP routing on Secure Firewall Threat Defense rather than relying on a single static default route?

An environment that exclusively uses transparent mode with no routing decisions made by the firewall

An environment with two equally capable upstream internet circuits where both should be actively utilized for outbound traffic rather than one sitting idle

An environment where all traffic must always take the exact same single path regardless of load

An environment with only a single upstream internet circuit and no redundancy requirement

An environment with no need for any outbound internet connectivity at all

An environment where only inbound traffic exists with no outbound traffic

9 / 10

Which troubleshooting approach would help determine whether traffic is being unevenly distributed across ECMP paths on Secure Firewall Threat Defense?

Physically disconnecting every equal-cost path except one with no further analysis, which is inconsistent with expected behavior

Reviewing per-path traffic statistics and flow distribution to compare actual utilization across the equal-cost routes

Relying solely on the device's power supply status indicator

Assuming distribution is always perfectly even with no verification needed

Disabling all routing entirely to check for even distribution

Relying solely on the building's physical security log

10 / 10

Which combination of interface and routing design choices would provide the most bandwidth-efficient and resilient connectivity for a Secure Firewall Threat Defense device with multiple upstream links to different providers offering equal-cost paths?

ECMP routing configured with mismatched administrative distances on every route

EtherChannel bundling on multi-link connections to a single provider where applicable, combined with ECMP routing across the equal-cost paths to different providers, and health monitoring on all links

EtherChannel bundling with no routing configuration linking the paths together at all

Relying solely on manual, per-packet administrator intervention for path selection

Disabling all interface health monitoring to simplify the configuration

A single unbundled interface to only one provider with no ECMP and no health monitoring, in accordance with common design practices, in most deployment scenarios, which is not the standard approach, in most deployment scenarios
