Choose all correct answers
Arrange steps in the correct order
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass 300-410 on their first attempt:
Answer before revealing
Read each 300-410 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which 300-410 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real 300-410 gives you roughly 1.3 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass 300-410 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 2,152+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 33 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.
A network engineer is troubleshooting an EIGRP adjacency issue between two directly connected routers, R1 and R2. Both routers are configured with the same autonomous system number, but the adjacency fails to come up. The engineer checks the interfaces and verifies that they are up/up. On R1, the output of 'show ip eigrp neighbors' shows nothing. What is the most likely cause of this problem?

A network engineer is troubleshooting an OSPFv2 adjacency issue between two directly connected routers, R1 and R2, both running IOS-XE. The link is a point-to-point Ethernet link. The engineer issues 'show ip ospf neighbor' on R1 and sees no neighbors. 'show ip ospf interface GigabitEthernet0/0' on R1 shows 'Network Type BROADCAST', but the link is actually a point-to-point link. Both routers have 'ip ospf 1 area 0' configured on the interface. What is the most likely cause of the adjacency not forming?

A network engineer is troubleshooting a BGP peering issue between two directly connected routers, R1 and R2. R1 is configured with 'neighbor 10.1.1.2 remote-as 65002' and 'neighbor 10.1.1.2 update-source Loopback0', while R2 uses 'neighbor 10.1.1.1 remote-as 65001' and 'neighbor 10.1.1.1 update-source Loopback0'. The loopback interfaces are not advertised into any IGP, and there is no static route for the loopback addresses. The BGP session remains in Idle state. What is the most likely cause?

A network engineer is troubleshooting a route redistribution issue between OSPF and EIGRP. Routers R1 (OSPF) and R2 (EIGRP) are redistributing routes into each other. The engineer notices that some OSPF external routes are not appearing in the EIGRP topology table on R2, although the redistribution is configured. The show ip eigrp topology command on R2 does not list the missing prefixes. What is the most likely cause?

A network engineer is troubleshooting a PBR configuration on a Cisco router. The engineer has configured a route map named 'PBR-MAP' with a match statement matching traffic from source IP 10.1.1.0/24 and a set statement to forward the traffic to next-hop 192.168.1.2. The engineer applies the route map to the incoming interface GigabitEthernet0/0 using 'ip policy route-map PBR-MAP'. However, traffic from 10.1.1.0/24 is still being forwarded using the routing table instead of the PBR next-hop. What is the most likely cause?

A network engineer is troubleshooting a BGP route filtering issue. Router R1 is advertising a prefix 10.1.1.0/24 to its eBGP neighbor R2, but R2 is not receiving it. The engineer checks R1's BGP configuration and sees a route-map named FILTER-OUT applied outbound to the neighbor. The route-map references an ACL that permits 10.1.1.0/24, but the prefix is still not being sent. What is the most likely cause?
Select an answer to reveal the explanation
A network engineer is troubleshooting a BGP route reachability issue. R1 learns the prefix 10.1.1.0/24 via eBGP from R2 with an AD of 20, and via OSPF from R3 with an AD of 110. The engineer notices that R1 installs the OSPF route in the routing table instead of the eBGP route, even though the eBGP route is preferred by default. What is the most likely cause of this behavior?

A network engineer is troubleshooting a connectivity issue between two branches connected via a WAN link. Router R1 (10.1.0.0/16) is summarizing its directly connected subnets (10.1.1.0/24, 10.1.2.0/24, 10.1.3.0/24) as a single 10.1.0.0/16 route to Router R2 via EIGRP. Users at R2 report that they cannot reach the 10.1.4.0/24 subnet, which was recently added to R1. What is the most likely cause of the problem?

A network engineer is troubleshooting an MPLS L3VPN where CE1 cannot reach CE2. The PE routers are running OSPF as the IGP and LDP for label distribution. On PE1, the engineer sees that the VRF route for CE2's subnet is present, but the corresponding MPLS label is missing in the LFIB. The show mpls ldp neighbor command shows LDP neighbors are up. What is the most likely cause of the missing label?

A network engineer is troubleshooting an MPLS L3VPN where CE1 (192.168.1.0/24) cannot reach CE2 (192.168.2.0/24). The PE routers are running OSPF with the CEs. On PE1, the VRF configuration includes route-target import and export 100:100. The show ip vrf detail command on PE1 shows the VRF is active, but the CE1 loopback is not present in the VRF routing table. The show ip route vrf CUSTOMER command on PE1 shows only directly connected interfaces. What is the most likely cause?

A network engineer is troubleshooting a DMVPN phase 2 hub-and-spoke deployment. The hub router has mGRE and NHRP configured, and spokes register successfully. However, spoke-to-spoke traffic is not being encrypted, even though IPsec profiles are applied to the mGRE tunnel interface on both the hub and spokes. The engineer verifies that the crypto map is not applied to the tunnel interface. What is the most likely cause of this issue?
Select an answer to reveal the explanation
A network engineer is troubleshooting an IPsec site-to-site VPN between two routers. The tunnel interface is up/up, but traffic from the local LAN to the remote LAN is not passing. The engineer checks the crypto map and sees it is applied to the outside interface. What is the most likely cause of the traffic failure?

A network engineer is troubleshooting an IPv6 connectivity issue between two sites connected via a 6to4 tunnel. The tunnel is configured on both routers and shows as up/up, but the engineer cannot ping the IPv6 address of the remote tunnel endpoint. The engineer checks the routing table and sees no route to the remote IPv6 prefix. What is the most likely cause of this problem?
Select an answer to reveal the explanation
A network engineer is troubleshooting a site-to-site VPN between two Cisco routers. The tunnel is up, but traffic is not passing. On R1, the engineer issues the command 'show crypto map' and sees that the crypto map is applied to the outbound interface. What is the most likely cause of the traffic failure?

A network engineer runs the following command on Router R1:
R1# show access-lists
Extended IP access list 101
10 permit tcp 192.168.1.0 0.0.0.255 any eq 80 (10 matches)
20 deny tcp any host 10.1.1.1 eq 22 (5 matches)
30 permit icmp any any (2 matches)
40 deny ip any any (1 match)Based on this output, which statement is correct?
Select an answer to reveal the explanation
A network engineer is troubleshooting a connectivity issue between two routers R1 and R2 connected via GigabitEthernet0/0. The engineer notices that R1 can ping its own IPv6 address 2001:db8:1::1/64, but cannot ping R2's interface address 2001:db8:1::2/64. The output of 'show ipv6 interface GigabitEthernet0/0' on R1 indicates that IPv6 is enabled and the interface is up/up. The engineer checks the access list applied to the interface and sees an inbound IPv6 ACL that permits only ICMPv6 echo requests from a specific source. What is the most likely cause of the ping failure?

A network engineer notices that BGP sessions between two directly connected routers are flapping every few minutes. The routers are running IOS-XE 17.3 and have CoPP enabled. The engineer checks the CoPP policy and sees a class-map matching BGP packets with a police rate of 8000 bps. The BGP session uses MD5 authentication and the routers exchange a full BGP table with 500,000 prefixes. What is the most likely cause of the BGP session flapping?
Select an answer to reveal the explanation
A network engineer is troubleshooting an IPv6 neighbor discovery issue on a switch running IOS-XE. Hosts on VLAN 100 are intermittently losing connectivity to the default gateway. The switch is configured with IPv6 First Hop Security features including RA Guard and DHCPv6 Guard. The engineer notices that the switch is dropping valid Router Advertisements from the legitimate router. What is the most likely cause of this issue?

Answer all 20 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing 300-410 on the first attempt. The most effective approach combines reading the official Cisco documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for 300-410 preparation:
Cover each 300-410 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing 300-410 score.
On exam day, the 300-410 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

No account required. Create a free account to unlock per-domain analytics and progress tracking across every certification on the platform. Courseiva is free forever, supported by advertising.
Every question is written against the official 300-410 exam blueprint published by Cisco. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass 300-410 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The 300-410 covers 33 domains: Layer 3 Technologies (35%), EIGRP Troubleshooting, OSPF Troubleshooting (v2/v3), BGP Troubleshooting, Route Redistribution, Policy-Based Routing (PBR), VRF-Lite, Route Maps and Route Filtering, Administrative Distance, Route Summarization, Bidirectional Forwarding Detection (BFD), VPN Technologies (20%), MPLS Operations, MPLS L3VPN, DMVPN, IPsec Site-to-Site VPN, IPv6 Tunneling Techniques, Infrastructure Security (20%), Device Access Control, IPv4 Access Control Lists, IPv6 Traffic Filtering and uRPF, Control Plane Policing (CoPP), IPv6 First Hop Security, Infrastructure Services (25%), Device Management, SNMP Troubleshooting, Network Logging and Syslog, Embedded Event Manager (EEM), IP SLA, NetFlow and Flexible NetFlow, SPAN, RSPAN, and ERSPAN, DHCP (IPv4 and IPv6), NAT and PAT. Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Layer 3 Technologies and Infrastructure Services — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Cisco's authorisation. Using them violates your NDA and Cisco's certification agreement, and can result in certification revocation. Courseiva questions are 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
