Domain 3 of the Cisco CCNA (200-301) exam. 120 questions on this domain in the full bank — here are four free samples with answers and explanations.

Question 1 · Difficulty 3/5

What is the primary purpose of a default route in a routing table?
  1. Forward packets with no matching specific route entry
  2. Route traffic between directly connected subnets
  3. Balance load across multiple equal-cost paths
  4. Advertise summary routes to neighboring routers
Show answer & explanation

Correct answer: A

Forward packets with no matching specific route entry
A default route (0.0.0.0/0) serves as the gateway of last resort, forwarding packets whose destination address does not match any more specific entry in the routing table. It is not used to route traffic between directly connected subnets, perform load balancing, or advertise summary routes.

Question 2 · Difficulty 4/5

When does a floating static route become active?
  1. Always active
  2. When primary route fails
  3. When interface is up
  4. When metric is lowest
Show answer & explanation

Correct answer: B

When primary route fails
Floating static routes have higher administrative distance and only become active when the primary route fails. They serve as backup routes.

Question 3 · Difficulty 3/5

Which protocol provides gateway redundancy?
  1. OSPF
  2. STP
  3. HSRP
  4. ARP
Show answer & explanation

Correct answer: C

HSRP
HSRP provides first-hop redundancy by creating a virtual gateway. OSPF is routing, STP prevents loops, ARP resolves MAC.

Question 4 · Difficulty 2/5

What is the default HSRP priority?
  1. 100
  2. 1
  3. 255
  4. 0
Show answer & explanation

Correct answer: A

100
Default HSRP priority is 100. Higher value becomes active router.
