3.0 IP Connectivity 200-301 Practice Quiz

• A. A routing table lists known routes and the information a router uses to choose where to forward packets.
• B. A routing protocol code identifies how a route was learned, such as connected, static, OSPF, or another source.
• C. A route prefix identifies the destination network or subnet in a routing table entry.
• D. A network mask or prefix length identifies which bits represent the network portion of an address.

A routing table lists known routes and the information a router uses to choose where to forward packets. This is the correct answer.

• A. Longest prefix match selects the route with the most specific matching prefix for the destination IP address.
• B. A routing protocol code identifies how a route was learned, such as connected, static, OSPF, or another source.
• C. A router forwarding decision uses the destination IP address, routing table, longest prefix match, and route attributes to choose an outgoing path.
• D. Route source preference uses administrative distance only when multiple sources advertise the same prefix length.

A routing protocol code identifies how a route was learned, such as connected, static, OSPF, or another source. This is the correct answer.

• A. IPv4 static route is the best match when the IP connectivity scenario requires this behavior: An IPv4 static route is a manually configured route for an IPv4 destination prefix.
• B. Routing table is the best match when the IP connectivity scenario requires this behavior: A routing table lists known routes and the information a router uses to choose where to forward packets.
• C. IPv6 static route is the best match when the IP connectivity scenario requires this behavior: An IPv6 static route is a manually configured route for an IPv6 destination prefix.
• D. Default route is the best match when the IP connectivity scenario requires this behavior: A default route matches destinations that do not match any more specific route.

A routing table lists known routes and the information a router uses to choose where to forward packets. This matches the IP connectivity scenario without confusing route selection, static routing, OSPF operation, or first-hop redundancy. This is the correct answer.

• A. Fully specified static route is the best match when the IP connectivity scenario requires this behavior: A fully specified static route includes both the exit interface and next-hop address.
• B. Exit-interface static route is the best match when the IP connectivity scenario requires this behavior: An exit-interface static route specifies the local outgoing interface used to forward traffic.
• C. Routing protocol code is the best match when the IP connectivity scenario requires this behavior: A routing protocol code identifies how a route was learned, such as connected, static, OSPF, or another source.
• D. Static route verification is the best match when the IP connectivity scenario requires this behavior: Static route verification confirms configured static routes appear in the routing table and forward traffic as intended.

A routing protocol code identifies how a route was learned, such as connected, static, OSPF, or another source. This matches the IP connectivity scenario without confusing route selection, static routing, OSPF operation, or first-hop redundancy. This is the correct answer.

• A. OSPF area is the best match when the IP connectivity scenario requires this behavior: An OSPF area groups routers and link-state information; single-area CCNA scenarios commonly use area 0.
• B. OSPF network command is the best match when the IP connectivity scenario requires this behavior: The OSPF network command enables OSPF on matching interfaces and assigns them to an area.
• C. OSPF passive interface is the best match when the IP connectivity scenario requires this behavior: An OSPF passive interface advertises the connected network but does not send OSPF hello packets on that interface.
• D. Route prefix is the best match when the IP connectivity scenario requires this behavior: A route prefix identifies the destination network or subnet in a routing table entry.

A route prefix identifies the destination network or subnet in a routing table entry. This matches the IP connectivity scenario without confusing route selection, static routing, OSPF operation, or first-hop redundancy. This is the correct answer.

• A. A scenario points to Single-area OSPFv2 when the routing or OSPF evidence depends on this distinction: Single-area OSPFv2 runs OSPF for IPv4 within one area, commonly area 0, to exchange routes dynamically.
• B. A scenario points to OSPF neighbor adjacency when the routing or OSPF evidence depends on this distinction: An OSPF neighbor adjacency is the relationship formed between OSPF routers that successfully exchange hello packets and required parameters.
• C. A scenario points to Routing table when the routing or OSPF evidence depends on this distinction: A routing table lists known routes and the information a router uses to choose where to forward packets.
• D. A scenario points to OSPF hello packets when the routing or OSPF evidence depends on this distinction: OSPF hello packets discover neighbors and maintain OSPF neighbor relationships.

A routing table lists known routes and the information a router uses to choose where to forward packets. This distinction matters because the wrong concept would lead to the wrong route-table interpretation, forwarding decision, OSPF verification, or gateway-redundancy conclusion. This is the correct answer.

• A. A scenario points to OSPF router ID selection when the routing or OSPF evidence depends on this distinction: OSPF router ID selection uses a manually configured router ID first, then the highest loopback IP, then the highest active physical interface IP.
• B. A scenario points to OSPF point-to-point network when the routing or OSPF evidence depends on this distinction: An OSPF point-to-point network type connects two routers without DR or BDR election.
• C. A scenario points to OSPF broadcast network when the routing or OSPF evidence depends on this distinction: An OSPF broadcast network type supports multiaccess Ethernet segments and uses DR/BDR election.
• D. A scenario points to Routing protocol code when the routing or OSPF evidence depends on this distinction: A routing protocol code identifies how a route was learned, such as connected, static, OSPF, or another source.

A routing protocol code identifies how a route was learned, such as connected, static, OSPF, or another source. This distinction matters because the wrong concept would lead to the wrong route-table interpretation, forwarding decision, OSPF verification, or gateway-redundancy conclusion. This is the correct answer.

• A. BDR election is the correct operational interpretation when the forwarding, route selection, OSPF, or FHRP decision depends on this exact meaning: Backup designated router election selects a standby router to take over if the DR fails.
• B. OSPF cost is the correct operational interpretation when the forwarding, route selection, OSPF, or FHRP decision depends on this exact meaning: OSPF cost is the metric used by OSPF to choose preferred paths.
• C. OSPF adjacency verification is the correct operational interpretation when the forwarding, route selection, OSPF, or FHRP decision depends on this exact meaning: OSPF adjacency verification checks neighbor state, interface participation, area, timers, and reachability to confirm OSPF operation.
• D. Routing table is the correct operational interpretation when the forwarding, route selection, OSPF, or FHRP decision depends on this exact meaning: A routing table lists known routes and the information a router uses to choose where to forward packets.

A routing table lists known routes and the information a router uses to choose where to forward packets. This applies the concept at the point where a Cisco administrator must predict routing behavior from prefixes, administrative distance, metrics, OSPF state, or default-gateway redundancy. This is the correct answer.
