CCNA IP Routing Practice Question
Which TWO statements about IPv4/IPv6 static routing are true?
⚠ Common exam trap
Cisco often tests the inverse relationship between administrative distance and route preference, trapping candidates who think a lower AD makes a route less preferred rather than more preferred.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
An IPv6 default static route can be configured using the destination prefix ::/0.
The IPv6 default static route uses the destination prefix ::/0, which matches all IPv6 addresses, similar to 0.0.0.0/0 in IPv4. Option D is correct because a floating static route is configured with a higher administrative distance and only becomes active when the primary route (with a lower AD) is removed or fails. Option A is wrong: a floating static route is configured with a higher administrative distance, not lower. Option C is wrong: a directly connected route has an administrative distance of 0, which is always preferred over a static route (even with AD 1). Option E is wrong: IPv4 static routes use the 'ip route' command, while IPv6 static routes use the 'ipv6 route' command; the syntax is different.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A floating static route is configured with a lower administrative distance than the primary route.
Why it's wrong here
For a floating static route to serve as a backup, it must be configured with a higher administrative distance than the primary route, not a lower one. A lower AD would cause the routing table to install the static route first, making it the active preferred path rather than a standby. Thus, the statement contradicts the very definition of a floating static route.
- ✓
An IPv6 default static route can be configured using the destination prefix ::/0.
Why this is correct
The IPv6 default static route uses the destination prefix ::/0, which matches any IPv6 address, analogous to IPv4's 0.0.0.0/0. It is commonly configured with the command 'ipv6 route ::/0' followed by a next-hop address or exit interface. This allows the router to forward all unmatched IPv6 traffic to a designated gateway.
- ✗
A static route with an administrative distance of 1 is preferred over a directly connected route.
Why it's wrong here
Directly connected routes always have an administrative distance of 0, the lowest possible value, so they are always preferred over any static route, including one with an AD of 1. A static route with AD 1 is still less trustworthy than a directly connected interface, because the router considers direct connectivity the most reliable source of routing information. Therefore, this statement is false.
- ✓
A floating static route becomes active in the routing table only when the primary route is removed or fails.
Why this is correct
A floating static route, because it has an administrative distance higher than the primary route, is not installed in the routing table while the primary route is present. It only becomes active when the primary route is removed from the table due to failure or administrative action. This behavior ensures that the backup route remains dormant until actually needed.
- ✗
IPv4 and IPv6 static routes are configured using the same command syntax.
Why it's wrong here
IPv4 and IPv6 static routes use different command syntax: IPv4 employs 'ip route' while IPv6 uses 'ipv6 route'. Additionally, the address formats differ substantially — IPv4 uses dotted-decimal, while IPv6 uses 128-bit hexadecimal colon-separated notation. Consequently, the configuration commands are not interchangeable.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

Why this is wrong here
The administrative distance must be higher (less preferred) for the floating static route to serve as a backup.

Why this is wrong here
Directly connected routes are always preferred over any static route because their AD is 0.

The commands are different; 'ip route' for IPv4 and 'ipv6 route' for IPv6.

Key term
IPv6
IPv6 is the most recent version of the Internet Protocol, designed to replace IPv4 by providing a vastly larger number of unique addresses and improved network features.
Key term
Connected route
A connected route is a network path that a router knows about automatically because it has a network interface directly connected to that network.
