19+ practice questions focused on Eigrp — one of the most tested topics on the ENCOR 350-401 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Eigrp PracticeA network engineer is configuring EIGRP on a router that connects to a service provider network. The engineer wants to advertise a default route to internal routers. The engineer configures 'ip default-network 0.0.0.0' and redistributes a static default route into EIGRP. However, internal routers are not receiving the default route. The engineer checks the EIGRP topology table and sees the default route with a metric of 1. What is the most likely reason?
Explanation: The engineer's configuration includes both 'ip default-network 0.0.0.0' (which is an IGRP command, not EIGRP) and redistribution of a static default route. The appearance of the default route in the EIGRP topology table with metric 1 indicates that redistribution occurred, but the route is not being advertised to internal routers. The most likely reason is that the static default route itself is not correctly configured. For EIGRP redistribution to succeed, the static route must point to a valid next-hop IP address using the syntax 'ip route 0.0.0.0 0.0.0.0 <next-hop>'. If the engineer used an interface instead of a next-hop, or the next-hop is unreachable, the static route may be invalid or not installed in the routing table, preventing its advertisement to EIGRP neighbors.
Examine the following EIGRP configuration on a Cisco IOS-XE device: router eigrp 100 network 10.0.0.0 0.255.255.255 passive-interface default no passive-interface GigabitEthernet0/0 ! interface GigabitEthernet0/0 ip address 10.1.1.1 255.255.255.0 ! interface GigabitEthernet0/1 ip address 10.2.2.1 255.255.255.0 Which statement is true?
Explanation: The 'passive-interface default' command sets all interfaces as passive, meaning they do not send or receive EIGRP hellos. The 'no passive-interface' command overrides this for specific interfaces.
Drag and drop the steps of EIGRP stub configuration for hub-and-spoke into the correct order, from first to last.
Explanation: The correct order ensures that the spoke router first enters EIGRP configuration, then configures the stub feature, optionally restricts stub types, and finally applies the configuration. The hub router does not need stub configuration.
Drag and drop the steps of EIGRP named mode configuration steps into the correct order, from first to last.
Explanation: Named mode starts with the router eigrp <virtual-name> command, then enters address-family configuration, configures the network, and optionally adjusts timers or other parameters. Finally, the configuration is verified.
Drag and drop the steps of EIGRP redistribution from OSPF with metric seeding into the correct order, from first to last.
Explanation: When redistributing OSPF into EIGRP with metric seeding, the correct order is: First, enter EIGRP router configuration mode (A). Second, if using named mode, specify the address-family (B). Third, set the default-metric (D) before redistribution to ensure routes receive proper metric values. Fourth, issue the 'redistribute ospf process-id' command (C). Finally, verify with 'show ip eigrp topology all-links' (E).

Practice all Eigrp questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Eigrp. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Eigrp questions on the 350-401 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Eigrp is tested as part of the ENCOR 350-401 blueprint. Practicing with targeted Eigrp questions ensures you can handle any format or difficulty that appears.
