Sample Cisco ENARSI 300-410 Practice Questions

Try these sample questions to review concepts for the Cisco ENARSI 300-410 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which routing protocol has the lowest default administrative distance for routes learned dynamically on a Cisco IOS router?
A.OSPF (110)
B.EIGRP internal (90)
C.iBGP (200)
D.RIP (120)
Explanation: On Cisco IOS, EIGRP internal routes have a default administrative distance of 90, which is lower than OSPF (110), RIP (120), iBGP (200), and external EIGRP (170). When the same destination is learned by multiple protocols, the route with the lowest AD is installed in the routing table.
2An engineer wants to change the administrative distance of a single OSPF external route to 130 so EIGRP wins for that prefix only. Which configuration achieves this?
A.Under router ospf 1: distance 130
B.Under router ospf 1: distance 130 0.0.0.0 255.255.255.255 1 (where ACL 1 permits the prefix)
C.Under router eigrp 1: distance 90 0.0.0.0 255.255.255.255
D.Under interface: ip ospf cost 130
Explanation: The distance command under an OSPF process accepts an ACL to selectively change the AD of routes from specific sources or prefixes. The syntax is distance <ad> <source-ip> <wildcard> <acl-number>, where the ACL filters which prefixes the new AD applies to. A bare distance 130 would change every OSPF route.
3Which Cisco IOS command applies a route-map named SET-MED to outbound BGP advertisements toward neighbor 10.1.1.2?
A.neighbor 10.1.1.2 route-map SET-MED in
B.neighbor 10.1.1.2 route-map SET-MED out
C.ip route-map SET-MED 10.1.1.2 out
D.redistribute route-map SET-MED 10.1.1.2
Explanation: Inside the BGP address-family or process, neighbor <ip> route-map <name> out applies the named route-map to updates sent to that neighbor. Using in instead would filter or modify routes received from that neighbor.
4A route-map clause that contains no match statement and is configured with a permit action behaves how?
A.Denies all routes
B.Permits all routes that reach the clause
C.Is rejected as invalid syntax
D.Acts the same as deny any
Explanation: A permit clause with no match statement matches every route that is evaluated against it and applies any set actions configured. This is commonly used as a final catch-all clause to allow remaining routes through after earlier clauses have filtered or modified specific prefixes.
5Which IKE Phase 1 mode uses three packet exchanges and protects peer identities by encrypting them after the Diffie-Hellman exchange?
A.Main mode
B.Aggressive mode
C.Quick mode
D.New Group mode
Explanation: IKEv1 Main mode uses six messages (often described as three exchanges) and authenticates peer identities AFTER establishing the encrypted channel. Aggressive mode uses three messages but exchanges identities in clear text. Quick mode is IKE Phase 2, and New Group mode renegotiates DH groups.
6Which Cisco IOS DHCP feature prevents a workstation on an untrusted port from leasing addresses by intercepting and validating DHCP messages against a binding table?
A.DHCP snooping
B.DHCP relay
C.ip helper-address
D.DHCP option 82 only
Explanation: DHCP snooping classifies switch ports as trusted or untrusted, blocks DHCP server messages on untrusted ports, and builds a binding table mapping IP-to-MAC-to-port. Other features like Dynamic ARP Inspection (DAI) and IP Source Guard depend on the snooping binding table for validation.
7Which command summarizes the EIGRP routes 10.1.0.0/24 through 10.1.3.0/24 outbound on an interface?
A.ip summary-address eigrp 100 10.1.0.0 255.255.252.0
B.summary-address eigrp 100 10.1.0.0/22
C.ip summary-address 10.1.0.0 0.0.3.255 eigrp 100
D.router eigrp 100 / network 10.1.0.0 0.0.3.255 summary
Explanation: EIGRP manual summarization is configured under the egress interface with ip summary-address eigrp <as> <network> <mask>. The four /24s combine into 10.1.0.0/22, which is mask 255.255.252.0. EIGRP automatically generates a corresponding Null0 summary route on the advertising router.
8What is the purpose of the Null0 route that EIGRP automatically installs when you configure manual summarization?
A.It is a backup path used when the summary fails
B.It prevents routing loops by discarding traffic for unknown subnets within the summary
C.It is used to advertise the summary to BGP neighbors
D.It improves convergence by feeding into the topology table
Explanation: When EIGRP advertises a summary, it installs a discard route to Null0 for the summary block on the advertising router. If a packet arrives for a subnet inside the summary that the router does not actually know, it would otherwise follow a default route and could loop back; the Null0 route drops it instead.
9An engineer enables policy-based routing on an interface but traffic is still routed by the destination-based table. Which command applies the route-map to the interface for inbound packets?
A.ip route-map PBR
B.ip policy route-map PBR
C.policy route-map PBR in
D.ip policy-based-routing PBR
Explanation: Policy-based routing is enabled on the ingress interface with ip policy route-map <name>. The router then evaluates the route-map for incoming packets and applies the set actions (next-hop, interface, etc.) before normal destination lookup.
10Which two commands are required to create a basic VRF named CUSTOMER and place interface GigabitEthernet0/1 into it on a router using legacy VRF-Lite syntax? (Choose the answer that lists both correct commands.)
A.ip vrf CUSTOMER and ip vrf forwarding CUSTOMER on the interface
B.vrf definition CUSTOMER and ip vrf CUSTOMER on the interface
C.vrf CUSTOMER and vrf member CUSTOMER on the interface
D.ip vrf CUSTOMER and vrf forwarding CUSTOMER on the interface
Explanation: Legacy IPv4-only VRF-Lite syntax uses ip vrf <name> at global config to create the VRF, then ip vrf forwarding <name> on the interface to bind the interface. Note that the newer multi-protocol syntax uses vrf definition <name> and vrf forwarding <name>; mixing the two forms causes errors.

About the Cisco ENARSI 300-410 Exam

Cisco ENARSI 300-410: Suggested Study Strategy

1Spend the most time on Layer 3 Technologies (35%) — drill EIGRP named-mode, OSPF LSA types and area types, and BGP attributes plus path selection until they are reflexive.
2Build a small lab in CML, EVE-NG, or GNS3 with at least four routers so you can practice redistribution, route maps, prefix lists, and AS_PATH access lists against real outputs.
3Memorize OSPF area type behavior (stub, totally stubby, NSSA, totally NSSA) and which LSA types each area filters — Cisco loves to test these distinctions.
4For BGP, practice the path-selection algorithm step by step (weight, local pref, locally originated, AS path length, origin, MED, eBGP over iBGP, IGP metric, oldest path, router ID).
5Configure a single-hub DMVPN with NHRP and IPsec end to end, then troubleshoot it with show ip nhrp, show dmvpn, and debug nhrp packet to internalize the control plane.
6Know the difference between CoPP (control plane policing on the global control plane) and CPPr (control plane protection that splits the control plane into host, transit, and CEF-exception subinterfaces).
7Practice IP SLA, NetFlow v5 vs v9 vs Flexible NetFlow, and SNMPv3 user/group/view configuration — services questions reward exact command syntax.
