CCNA IP Routing Practice Test 20 — 15 Questions

Question 1

Drag and drop the following steps into the correct order to configure a single-area OSPFv2 network on two Cisco routers (R1 and R2) and observe the neighbor state transitions from Down to Full.

Accepted Answer

Configure OSPF process and router-id on R1, then add the network; repeat on R2; ensure interfaces are up; finally verify neighbor states.. First configure OSPF process and router-id on R1, then add the network; repeat on R2; ensure interfaces are up; finally verify neighbor states to see the full transition sequence.

Answer

Configure OSPF process and router-id on R1, then ensure interfaces are up; repeat on R2; add the network; finally verify neighbor states.

Answer

Ensure interfaces are up on both routers, then configure OSPF process and router-id on R1; add the network; repeat on R2; finally verify neighbor states.

Answer

Configure OSPF process and router-id on R1, then add the network; ensure interfaces are up; repeat on R2; finally verify neighbor states.

Question 2

Drag and drop the following OSPFv2 neighbor state transitions into the correct order, starting from the initial Down state on a broadcast or point-to-point network (non-NBMA).

Accepted Answer

Down, Init, 2-Way, ExStart, Exchange. The standard OSPF neighbor state machine on broadcast and point-to-point networks proceeds: Down, Init, 2-Way, ExStart, Exchange, Loading, Full. The Attempt state exists only on NBMA networks and is not used here. Option D correctly lists the first five states in order: Down → Init → 2-Way → ExStart → Exchange. Other options incorrectly include the NBMA-only Attempt state or misorder the states like Loading before Exchange.

Answer

Down, Attempt, Init, 2-Way, ExStart

Answer

Down, Init, 2-Way, ExStart, Loading

Answer

Down, Init, Attempt, 2-Way, ExStart

Question 3

Drag and drop the following OSPFv2 neighbor state transitions into the correct order, starting from the initial state when no neighbor information has been received.

Accepted Answer

Down, Init, 2-Way, ExStart, Exchange. OSPF neighbor states begin at Down, then Init after receiving Hello, 2-Way after seeing own router ID, ExStart for master/slave negotiation, and Exchange for exchanging database descriptors.

Answer

Down, 2-Way, Init, ExStart, Exchange

Answer

Down, Init, ExStart, 2-Way, Exchange

Answer

Down, Init, 2-Way, Exchange, ExStart

Question 4

Drag and drop the following OSPFv2 neighbor state transitions and DR/BDR election steps into the correct order for a multi-access network where a new router joins an existing OSPF area.

Accepted Answer

Down -> Init -> 2-Way -> ExStart -> Exchange -> Loading -> Full. The new router first discovers neighbors via Hello. Then DD, LSR, LSU exchange synchronizes databases. DR/BDR election happens before Full state is achieved.

Answer

Down -> Init -> 2-Way -> ExStart -> Exchange -> Full -> Loading

Answer

Down -> Init -> ExStart -> 2-Way -> Exchange -> Loading -> Full

Answer

Down -> Init -> 2-Way -> Exchange -> ExStart -> Loading -> Full

Question 5

Drag and drop the following OSPFv2 neighbor state transitions and DR/BDR election steps into the correct order for a multi-access network with default priority values.

Accepted Answer

Down, Init, 2-Way (DR/BDR election), ExStart, Exchange, Loading, Full. The correct OSPF neighbor state progression on a multi-access network is: Down, Init, 2-Way (with DR/BDR election), ExStart (master/slave negotiation), Exchange (DBD exchange), Loading (link-state request and update), and Full. Each option missing the Loading state or placing it incorrectly fails to represent the complete adjacency process.

Answer

Down, Init, ExStart, Exchange, Loading, 2-Way (DR/BDR election), Full

Answer

Down, Init, 2-Way (DR/BDR election), Loading, Exchange, ExStart, Full

Answer

Down, Init, 2-Way (DR/BDR election), ExStart, Exchange, Full

Question 6

Drag and drop the following steps into the correct order to configure OSPFv3 for IPv6 on a Cisco IOS-XE router.

Accepted Answer

Enable IPv6 routing globally with 'ipv6 unicast-routing'. The correct order is A, B, C, D. First, enable IPv6 routing globally with 'ipv6 unicast-routing'. Next, enter OSPFv3 configuration mode using 'router ospfv3 1'. Then, configure each interface with 'ipv6 ospf area '. Finally, verify OSPFv3 neighbor adjacency with 'show ipv6 ospf neighbor' to confirm successful adjacency formation.

Question 7

Drag and drop the following commands into the correct order to configure OSPFv3 for IPv6 on a Cisco IOS-XE router.

Accepted Answer

ipv6 unicast-routing. The correct sequence for configuring OSPFv3 on a Cisco IOS-XE router is: first enable IPv6 routing globally with `ipv6 unicast-routing` (A), then create the OSPFv3 process with `router ospfv3 1` (B), then enter interface configuration mode for the desired interface with `interface GigabitEthernet0/0` (C), and finally enable OSPFv3 on that interface using `ipv6 ospf 1 area 0` (D). This order ensures IPv6 is enabled before configuring OSPFv3, the OSPFv3 process exists before it is assigned to an interface, and the interface is selected before applying the OSPFv3 configuration.

Question 8

Drag and drop the following commands into the correct order to configure OSPFv3 for IPv6 on a Cisco router.

Accepted Answer

ipv6 unicast-routing. Commands must be executed in order: global config, IPv6 routing, interface config, OSPFv3 on interface, then verification.

Question 9

Drag and drop the following steps into the correct order to configure OSPFv3 for IPv6 on a Cisco router.

Accepted Answer

1. Enter global configuration mode. 2. Create the OSPFv3 process and assign a process ID. 3. Configure a router ID. 4. Enter interface configuration mode. 5. Enable OSPFv3 on the interface.. After entering global config, create the OSPFv3 process, set a router ID, then enable OSPFv3 on the desired interfaces under interface configuration.

Answer

1. Enter global configuration mode. 2. Enter interface configuration mode. 3. Enable OSPFv3 on the interface. 4. Create the OSPFv3 process and assign a process ID. 5. Configure a router ID.

Answer

1. Enter global configuration mode. 2. Create the OSPFv3 process and assign a process ID. 3. Enter interface configuration mode. 4. Enable OSPFv3 on the interface. 5. Configure a router ID.

Answer

1. Enter global configuration mode. 2. Configure a router ID. 3. Enter interface configuration mode. 4. Enable OSPFv3 on the interface. 5. Create the OSPFv3 process and assign a process ID.

Question 10

Which TWO statements accurately describe OSPFv3 configuration and verification for IPv6?

Accepted Answer

OSPFv3 uses IPv6 link-local addresses for neighbor discovery and next-hop addresses.. OSPFv3 uses IPv6 link-local addresses for neighbor discovery and next-hop addresses. Option C is correct because the 'ipv6 ospf area ' interface command enables OSPFv3 on that interface. Option B is incorrect: OSPFv3 does not use the 'network' command; instead, it relies on interface-level configuration. Option D is incorrect: 'ipv6 router ospf ' is a global configuration command to enter OSPFv3 router configuration mode, not an interface command. Option E is incorrect: 'show ipv6 ospf neighbor' displays neighbor adjacencies, not the link-state database; use 'show ipv6 ospf database' for that.

Answer

The 'network' command under 'ipv6 router ospf' is used to advertise subnets into OSPFv3.

Answer

The 'ipv6 router ospf <process-id>' command is used on an interface to enable OSPFv3.

Answer

The 'show ipv6 ospf neighbor' command displays the OSPFv3 link-state database.

Question 11

Drag and drop the following steps into the correct order to configure HSRP version 2 on an interface and ensure the router becomes the active router, then verify the HSRP state.

Accepted Answer

1. Configure HSRP version 2 on the interface
2. Configure the HSRP group and virtual IP address
3. Set the HSRP priority to a higher value
4. Enable HSRP preempt
5. Verify HSRP state using show standby. The correct order for configuring HSRP version 2 to ensure the router becomes the active router is: first configure HSRP version 2 on the interface, then configure the HSRP group and virtual IP address, then set the HSRP priority to a higher value, then enable HSRP preempt, and finally verify using 'show standby'. Only option A follows this sequence. Options B, C, and D are incorrect because they place version after group, priority before version, or preempt before priority.

Answer

1. Configure the HSRP group and virtual IP address
2. Set the HSRP priority to a higher value
3. Enable HSRP preempt
4. Configure HSRP version 2 on the interface
5. Verify HSRP state using show standby

Answer

1. Configure the HSRP virtual IP address. 2. Configure the interface with an IP address. 3. Configure the HSRP priority. 4. Enable HSRP preempt. 5. Verify HSRP status. 6. Test failover.

Question 13

Drag and drop the following steps into the correct order to configure HSRP on an interface and verify the active/standby election process, including failover and verification.

Accepted Answer

Enter interface configuration mode, set HSRP version, configure virtual IP, set priority (if needed), enable preempt, then verify with 'show standby'.. Only option A correctly orders the steps for configuring HSRP on an interface. The proper sequence is: enter interface configuration mode, set the HSRP version, configure the virtual IP, set priority if needed, enable preempt, and verify with 'show standby'. Options B, C, and D contain incorrect steps or order. B suggests creating a VLAN and assigning an IP to the VLAN interface, which is not part of HSRP configuration (HSRP is configured on an existing Layer 3 interface, not by creating a VLAN). C places priority before virtual IP and uses 'show running-config' for verification, which does not show active/standby roles. D incorrectly assumes HSRP is enabled globally and uses 'debug standby' for initial verification, which is not the standard first verification command.

Answer

Enter global configuration mode, create a VLAN, assign an IP address, then enable HSRP on the VLAN interface.

Answer

Configure HSRP priority first, then set the virtual IP, then enter interface configuration mode, and finally verify with 'show running-config'.

Answer

Enable HSRP globally with a 'router hsrp' command, then assign the virtual IP on the interface, and verify with 'debug standby'.

Question 14

Drag and drop the following steps into the correct order to configure HSRP on a router and verify the active/standby election process.

Accepted Answer

1. Enter interface configuration mode on the desired interface. 2. Configure the HSRP group number and virtual IP address using the 'standby group-number ip virtual-ip' command. 3. Set the HSRP priority using the 'standby group-number priority priority-value' command. 4. Enable preemption using the 'standby group-number preempt' command. 5. Verify the HSRP state using 'show standby' or 'show standby brief'. 6. Test failover by shutting down the active router's interface and observing the state change.. The correct order to configure HSRP is: first enter interface configuration mode, then configure the HSRP group number and virtual IP using 'standby group-number ip virtual-ip', then set priority with 'standby group-number priority value', then enable preemption with 'standby group-number preempt', then verify the initial state using 'show standby' or 'show standby brief', and finally test failover by shutting down the active interface and observing the state change. Options B, C, and D are incorrect because they either set priority before configuring the virtual IP, enable preemption before setting priority, or place verification after failover testing, which does not match the correct sequence.

Answer

1. Enter interface configuration mode. 2. Set the HSRP priority. 3. Configure the HSRP group number and virtual IP. 4. Enable preemption. 5. Test failover. 6. Verify the HSRP state.
