There is a spanning tree mismatch at the global level. PVST+ is configured on a VLT peer. All VLT port channels go down on both VLT peers. A syslog error message is generated. What is the correct action to resolve the issue?
Correct Answer:
D
Explanation
Policy-Based Routing allows you to make forwarding decisions based on criteria beyond just the destination address, such as the source IP address. In this case, the administrator can create a policy that matches traffic sourced from Host-1 and directs it to a specific next-hop address. Standard routing uses only destination-based lookups, so it cannot differentiate based on source. ACLs filter traffic but do not reroute it. Route maps are related but policy-based routing is the direct feature that implements source-based routing decisions.
Which LSA type provides information necessary to reach routers originating type 5 LSA's in other areas?
Correct Answer:
A
Explanation
After a DHCP server sends an offer, the client responds with a DHCP Request message sent as a unicast frame directly to the server that made the offer. The client uses the server's MAC address obtained from the offer message. Broadcast would be inefficient at this stage since the client has already identified the server. A unicast response confirms the client's intention to accept that specific offer and allows faster processing by the server.
Which commands are required to properly configure an OS10 switch to run OSPF on eth1/1/3 and to add network 144.254.1.0/30 to OSPF area 0?
Correct Answer:
C
Explanation
In a single area OSPF topology, three LSA types are used. Type 1 LSAs describe the router and its interfaces. Type 2 LSAs represent the designated router on a multi-access network segment. Type 5 LSAs describe external routes redistributed into OSPF. Types 3, 4, and 7 are only used when multiple areas exist, so they do not appear in a single area design.
In a PIM Sparse Mode (PIM-SM) based multicast topology, what function does the Rendezvous Point provide?
Correct Answer:
C
Explanation
LLDP on OS10 supports a maximum of 250 neighbors per system. This limit defines how many discovered LLDP devices can be tracked simultaneously. Smaller numbers would be too restrictive for larger deployments. The 250 neighbor limit is a design specification built into the OS10 platform and is documented in Dell EMC's technical specifications.
What version of IGMP is required by PIM-SSM receivers?
Correct Answer:
B
Explanation
When BGP peering fails, the BGP state remains IDLE or CONNECT rather than ESTABLISHED. Issuing the no shutdown command activates the BGP neighbor configuration if it is currently shut down. Verifying that the state changes to ESTABLISHED confirms the peering is working. Without this step, the neighbor remains inactive and the peer relationship never forms. The recommendation combines both the action to fix the problem and the verification step to confirm resolution.
Which LSA type contains information about routes redistributed into OSPF?
Correct Answer:
C
Explanation
RSTP priority values range from 0 to 61440 in increments of 4096. This range applies to all RSTP capable switches including OS10. The lower the priority value, the higher the priority for becoming root bridge. Values outside this range are invalid. Understanding the correct RSTP priority range is essential for proper spanning tree topology control and root bridge selection.

FAQ
D-NWG-FN-23 Exam FAQ
Common questions about the exam itself
What background do I need before taking the D-NWG-FN-23 exam?
You should have hands-on experience with Dell Technologies networking products or have completed recommended training. The certification assumes basic familiarity with network devices and their configuration.
Which topic in D-NWG-FN-23 causes most candidates trouble?
Ethernet Technologies is the largest domain at 40% of the exam and commonly trips up candidates on VLAN tagging, frame structure, and switching behavior in real traffic flows. Candidates find IP Networking challenging too, especially subnetting, longest prefix match routing, and IPv6 address formatting.
How long should I study for the D-NWG-FN-23 exam?
Most candidates spend 4 to 8 weeks preparing with hands-on practice, depending on existing network knowledge. You need time to build practical experience with Dell switches in addition to studying the objectives.
How many questions are on D-NWG-FN-23 and what format are they?
The exam contains multiple choice and scenario-based questions delivered over 90 minutes. The exact question count varies, but expect a mix of single-select and multi-select questions that test both knowledge and practical troubleshooting.
What happens if I fail the D-NWG-FN-23 exam?
Dell allows retakes of the exam. You can reschedule through the testing center and sit the exam again. Review your weak domains from the failed attempt before your next try.
How is the Dell Networking Foundations certification different from entry-level networking exams?
D-NWG-FN-23 is specifically tailored to Dell and Dell EMC switching and routing products. It goes deeper into product-specific configuration than generic vendor-neutral networking certifications.
How long is the Dell Networking Foundations certification valid?
You should verify the current validity period with Dell Learning, as certification maintenance requirements may vary. Check your CertTracker account after passing to confirm your certification details.
What job role does the D-NWG-FN-23 certification prepare me for?
This certification targets network technicians and junior network engineers responsible for installing, configuring, maintaining, and basic troubleshooting of Dell Technologies networking products.
Can I sit D-NWG-FN-23 online or must I go to a test center?
Confirm the current delivery options with Dell Learning or your testing provider, as exam delivery methods can change. The exam may be available both online proctored and at physical test centers.
What is the passing score for D-NWG-FN-23?
You should verify the current passing score with Dell Learning's official exam page. The score requirement determines how many questions you need to answer correctly to pass.
