How many DHCP Troubleshooting Scenarios questions are on this page?

This page has 6 DHCP Troubleshooting Scenarios scenario questions for the 350-701 exam, each with detailed explanations and wrong-answer analysis.

How should I approach 350-701 scenario questions?

Read the full scenario before looking at the answer options. Identify the constraint or requirement in the scenario, then eliminate options that are generally true but wrong for this specific case. Scenario questions reward careful reading over pattern matching.

Scenario guide

How to approach dhcp troubleshooting scenarios

DHCP questions cover server configuration, relay agents (ip helper-address), DHCP snooping, and the four-step DORA handshake. Common exam scenarios: a host isn't getting an IP, a relay agent isn't forwarding requests, or a rogue DHCP server is handing out wrong addresses.

Quick answer

DHCP questions usually test address assignment, scopes, relay agents, excluded addresses and why a client cannot obtain an IP address.

DHCP discovery, offer, request and acknowledgement flow.

DHCP scopes, excluded addresses and default gateway options.

DHCP relay using helper addresses.

Troubleshooting clients that receive APIPA or no address.

An engineer is troubleshooting a Cisco ISE deployment where some endpoints are not being profiled correctly. The administrator notices that the endpoints are not sending DHCP requests. Which profiling probe should be primarily used to identify these endpoints?

A
NetFlow probe
NetFlow probe analyzes traffic flows and can profile endpoints based on IP and port information.
B
DHCP probe
Why wrong: DHCP probe relies on DHCP traffic, which is not present.
C
HTTP probe
Why wrong: HTTP probe requires HTTP traffic, which may not be present.
D
DNS probe
Why wrong: DNS probe can identify hostnames but not if DNS queries are not sent.

In Cisco ISE, profiling is used to identify device types. Which probe must be enabled for ISE to determine the operating system of a device by analyzing DHCP options?

A
Device Sensor
Why wrong: Device Sensor is a feature on network devices that sends endpoint attributes to ISE but is not a probe that analyzes DHCP packets directly.
B
DHCP Probe
Correct. DHCP Probe extracts device information from DHCP packets for profiling.
C
HTTP Probe
Why wrong: HTTP Probe analyzes HTTP user-agent strings but not DHCP options.
D
SNMP Probe
Why wrong: SNMP Probe gathers information from SNMP-enabled devices but does not analyze DHCP packets.

A network administrator configures Cisco ISE to identify devices by analyzing DHCP requests, HTTP user agents, and SNMP queries. Which ISE feature is being used?

A
TrustSec
Why wrong: TrustSec assigns SGTs for segmentation, not device identification.
B
Profiling
Profiling uses probes to determine device type and characteristics.
C
Guest access
Why wrong: Guest access provides temporary network access, not device identification.
D
Posture assessment
Why wrong: Posture checks security compliance, not device identity.

Question 4hardmultiple choice

A network administrator is configuring Cisco ISE for device profiling. The goal is to identify the type of device (e.g., Windows PC, iPhone, printer) connecting to the network. Which probe should be used to gather the DHCP option 60 (vendor class identifier) and option 12 (hostname) information?

A
DHCP probe
The DHCP probe captures DHCP packets and extracts options like vendor class and hostname.
B
Cisco Device Sensor
Why wrong: Device Sensor is used on switches to send telemetry to ISE, but DHCP probes are separate.
C
SNMP probe
Why wrong: SNMP probe queries device MIBs but does not capture DHCP options.
D
HTTP probe
Why wrong: HTTP probe collects browser User-Agent strings but not DHCP options.

Drag and drop the steps to configure a Cisco router as a DHCP server in the correct order.

Drag steps to the numbered slots on the right, or tap a step then tap a slot.

1Step 1

2Step 2

3Step 3

4Step 4

5Step 5

A
Exclude addresses, then Create the DHCP pool, then Specify the network and subnet mask, then Set the default-router and dns-server options.
This is the correct order because you first exclude addresses to prevent them from being assigned, then create the DHCP pool, specify the network that will be used for dynamic allocation, and finally set the default gateway and DNS server options.
B
Create the DHCP pool, then Exclude addresses, then Set the default-router and dns-server options, then Specify the network and subnet mask.
Why wrong: This is incorrect because specifying the network must come before setting options like default-router and dns-server, as these options are associated with the pool's network range.
C
Specify the network and subnet mask, then Create the DHCP pool, then Exclude addresses, then Set the default-router and dns-server options.
Why wrong: This is incorrect because the DHCP pool must be created before specifying the network; the network command is entered in the DHCP pool configuration mode.
D
Set the default-router and dns-server options, then Specify the network and subnet mask, then Create the DHCP pool, then Exclude addresses.
Why wrong: This is incorrect because the pool must be created and the network specified before any options can be set; options are configured under the pool context after the network is defined.

Cisco ISE uses profiling to identify the type of device connecting to the network. Which probe helps ISE identify a device by analyzing the DHCP requests it sends?

A
HTTP probe
Why wrong: HTTP probe analyzes HTTP traffic to identify device type.
B
Device Sensor
Why wrong: Device Sensor is a different feature that collects device attributes, but the probe specifically for DHCP is the DHCP probe.
C
SNMP probe
Why wrong: SNMP probe queries network devices for information.
D
DHCP probe
DHCP probe analyzes DHCP packets to extract device information.
