Domain 3.0 is 20% of CCNA v2.0. Topics: reading the routing table (prefix, administrative distance, metric, default route), IPv4 and IPv6 static, host and floating static routes, single-area OSPFv2 and OSPFv3, and HSRP and VRRP status.

CCNA v2.0 starts February 3, 2027 and runs 120 minutes. The current v1.1 exam is available until February 2, 2027.

Domain sample questions with answers

IP Routing

CCNA v2.0 sample question 1

R1 must forward a packet to 10.10.20.70. Its routing table contains:

O        10.10.0.0/16 [110/30] via 10.0.0.2, Gi0/0
S        10.10.20.0/24 [1/0] via 10.0.0.6
O        10.10.20.0/26 [110/40] via 10.0.0.10, Gi0/2
S*    0.0.0.0/0 [1/0] via 203.0.113.1

Which next hop does R1 use?

  1. 10.0.0.10
  2. 10.0.0.2
  3. 10.0.0.6
  4. 203.0.113.1
Show correct answer and explanation

Correct answer: C. 10.0.0.6

C is correct because 10.10.20.0/26 covers only .0 to .63, so the longest prefix that contains .70 is the /24 static route. A would be used only for .0 to .63, because the /26 does not contain 10.10.20.70. B is the less specific /16, which loses to the matching /24. D is the default route, used only when no other entry matches the destination.

IP Routing

CCNA v2.0 sample question 2

A packet for 172.16.47.9 arrives at R2, whose routing table shows:

D        172.16.0.0/16 [90/3072] via 192.168.1.2, Gi0/0
O        172.16.32.0/20 [110/65] via 192.168.1.6, Gi0/1
S        172.16.40.0/24 [1/0] via 192.168.1.10

Which next hop does R2 choose?

  1. None, because no route matches exactly
  2. 192.168.1.6
  3. 192.168.1.10
  4. 192.168.1.2
Show correct answer and explanation

Correct answer: B. 192.168.1.6

B is correct because 172.16.32.0/20 spans 172.16.32.0 to 172.16.47.255, and it is the longest prefix that contains the destination. A is wrong, because a route only has to contain the destination, not equal it. C is the static /24, which covers only 172.16.40.0 to 172.16.40.255. D has the lower administrative distance, but distance is compared only for the same prefix, not across a /16 and a /20.

IP Routing

CCNA v2.0 sample question 3

R3 shows this entry for a remote network:

O        10.30.0.0/16 [110/30] via 10.0.1.2, 00:04:11, GigabitEthernet0/0
                      [110/30] via 10.0.2.2, 00:04:11, GigabitEthernet0/1

How does R3 forward traffic for 10.30.5.5?

  1. It uses only 10.0.1.2, because it is listed first
  2. It drops the traffic until one path is removed
  3. It shares the traffic across both next hops
  4. It uses only Gi0/1, because it has the higher interface number
Show correct answer and explanation

Correct answer: C. It shares the traffic across both next hops

C is correct because two via lines with the same distance and cost are equal-cost paths, and IOS load-balances across them. A is wrong, because the order of the via lines does not make the first path a primary. B is wrong, because duplicate equal-cost paths are normal and both are used. D is wrong, because interface numbering plays no part in path selection.

IP Routing

CCNA v2.0 sample question 4

A user on R1's LAN sends a packet to 172.16.5.5. R1's routing table shows:

Gateway of last resort is not set

C     192.168.1.0/24 is directly connected, GigabitEthernet0/0
O     10.0.0.0/8 [110/20] via 192.168.1.254, GigabitEthernet0/0

What does R1 do with the packet?

  1. Forwards it to 192.168.1.254, the only next hop
  2. Sends an ARP request for 172.16.5.5 on Gi0/0
  3. Floods it out every interface except Gi0/0
  4. Drops it and returns ICMP destination unreachable
Show correct answer and explanation

Correct answer: D. Drops it and returns ICMP destination unreachable

D is correct because nothing matches 172.16.5.5 and there is no default route, so the router discards the packet and notifies the sender. A would require a route that contains 172.16.5.5, and 10.0.0.0/8 does not. B happens only for destinations on a connected subnet, and 172.16.5.5 is not on 192.168.1.0/24. C describes a switch with an unknown MAC address, not a router with no route.

IP Routing

CCNA v2.0 sample question 5

R1 receives a ping addressed to 192.168.10.1, and its table includes:

C        192.168.10.0/24 is directly connected, GigabitEthernet0/0
L        192.168.10.1/32 is directly connected, GigabitEthernet0/0
S*    0.0.0.0/0 [1/0] via 192.168.10.254

Which statement describes how R1 handles the ping?

  1. It follows the default route to 192.168.10.254
  2. It matches the C route and R1 sends an ARP for .1
  3. It is dropped because two routes point to Gi0/0
  4. It matches the L /32 route and R1 replies itself
Show correct answer and explanation

Correct answer: D. It matches the L /32 route and R1 replies itself

D is correct because the local /32 is the longest match and marks the address as R1's own, so the packet is processed by R1. A is wrong, because the default is used only when nothing more specific matches. B is wrong, because the /32 local route is more specific than the connected /24. C is wrong, because a connected and a local entry on the same interface are normal.

IP Routing

CCNA v2.0 sample question 6

An engineer sees this entry on R4:

O IA     10.50.0.0/16 [110/74] via 10.0.4.1, 00:22:10, GigabitEthernet0/0

What does the O IA code indicate about the route?

  1. It is a static route redistributed into OSPF
  2. OSPF learned it from outside the OSPF domain
  3. It is an OSPF route with an internal administrative distance of 74
  4. OSPF learned it from a different OSPF area
Show correct answer and explanation

Correct answer: D. OSPF learned it from a different OSPF area

D is correct because the IA (inter-area) tag means an area border router advertised the prefix from another area. A would appear as an external route, such as O E2. B describes the external codes O E1 and O E2, not O IA. C misreads the brackets, where 110 is the distance and 74 is the cost.

IP Routing

CCNA v2.0 sample question 7

The routing table on branch router R5 begins with these lines:

Gateway of last resort is 10.0.12.1 to network 0.0.0.0

O* E2 0.0.0.0/0 [110/1] via 10.0.12.1, 00:03:10, GigabitEthernet0/1

What do these lines show about the default route?

  1. OSPF learned it as an external route from another router
  2. The default route is one hop away from R5
  3. An administrator configured a static default on R5
  4. OSPF learned it from another area in the same domain
Show correct answer and explanation

Correct answer: A. OSPF learned it as an external route from another router

A is correct because O E2 marks an OSPF external type 2 route, typically injected by a router running default-information originate. B misreads the metric 1, which is the external type 2 cost and not a hop count. C would show the code S and a distance of 1, not O E2 with 110. D describes O IA, which is an inter-area route, not an external one.

IP Routing

CCNA v2.0 sample question 8

R1 has this static route configured:

ip route 10.80.0.0 255.255.0.0 192.168.2.2

OSPF also advertises 10.80.0.0/16 to R1 through 192.168.3.2. Which next hop does R1 install for 10.80.0.0/16?

  1. Both next hops, sharing the load
  2. Whichever route was learned most recently
  3. 192.168.3.2, from the OSPF route
  4. 192.168.2.2, from the static route
Show correct answer and explanation

Correct answer: D. 192.168.2.2, from the static route

D is correct because for the identical prefix the lower administrative distance wins, and a static route (1) beats OSPF (110). A is wrong, because routes from different sources with different distances are not load-balanced. B is wrong, because IOS selects by distance, not by age. C would win only if the static route were given a distance above 110.

IP Routing

CCNA v2.0 sample question 9

R2 must forward a packet to 2001:db8:20:5::9. show ipv6 route on R2 shows:

C   2001:DB8:10:1::/64 [0/0] via GigabitEthernet0/0, directly connected
L   2001:DB8:10:1::1/128 [0/0] via GigabitEthernet0/0, receive
O   2001:DB8:20::/48 [110/2] via FE80::2, GigabitEthernet0/1
S   ::/0 [1/0] via 2001:DB8:10:1::FE

Where does R2 send the packet?

  1. Nowhere, because FE80::2 is not a routable next hop
  2. To FE80::2 out GigabitEthernet0/1
  3. To 2001:DB8:10:1::FE through the default route
  4. Directly out GigabitEthernet0/0 to the host
Show correct answer and explanation

Correct answer: B. To FE80::2 out GigabitEthernet0/1

B is correct because the destination falls inside 2001:db8:20::/48, which is longer than ::/0, and OSPFv3 uses the neighbor's link-local next hop. A is wrong, because a link-local address is a valid next hop when the exit interface is known. C is used only when no more specific prefix contains the destination. D is wrong, because the destination is not inside the connected 2001:db8:10:1::/64.

IP Routing

CCNA v2.0 sample question 10

R1 must forward a packet to 192.168.20.55. Its routing table includes:

C        192.168.20.0/24 is directly connected, GigabitEthernet0/2
L        192.168.20.1/32 is directly connected, GigabitEthernet0/2
S*    0.0.0.0/0 [1/0] via 203.0.113.1

What does R1 do next?

  1. It drops the packet since no next-hop address is listed
  2. It ARPs for 192.168.20.55 on Gi0/2 and delivers the packet
  3. It forwards the packet to 203.0.113.1 by default
  4. It ARPs for 192.168.20.1 and forwards to it
Show correct answer and explanation

Correct answer: B. It ARPs for 192.168.20.55 on Gi0/2 and delivers the packet

B is correct because the connected /24 contains the destination, so R1 resolves the host's own MAC address on that segment. A is wrong, because a connected route needs no next hop; the host is reached directly. C is wrong, because the connected /24 is more specific than the default route. D is wrong, because 192.168.20.1 is R1's own address, shown by the L route.
