Question 360
R1 has two installed, reachable routes: an OSPF `10.10.0.0/16 [110/20] via 192.0.2.2` and a high-distance static `10.10.16.128/25 [200/0] via 192.0.2.3`. A packet targets 10.10.16.178. Which next hop is used?
- 192.0.2.3, because the installed /25 is more specific
- 192.0.2.2, because OSPF has a lower administrative distance
- Both next hops in equal-cost balancing despite unequal prefixes
- Neither; a static route can never forward while OSPF is running
Explanation
Correct Answer
A:Forwarding selects the longest matching *installed* prefix, so the /25 covers .178 and wins even with a higher administrative distance than the /16.
Incorrect Answers
B:Administrative distance compares sources competing for the same prefix during installation; it does not override a more-specific installed route at forwarding time.
C:ECMP concerns equal-cost eligible paths to the same prefix, not two unequal prefix lengths.
D:Static routes can coexist with OSPF routes for different masks when each route is installed and reachable.
Question 361
R1 learns 198.51.100.0/24 through OSPF with administrative distance 110 and has a reachable static route to the same /24 with distance 1. Which source is installed by default?
- The reachable static route
- Both routes as ECMP despite different distances
- The OSPF route because its metric is dynamic
- Neither route until a default route is added
Explanation
Correct Answer
A:For equal prefixes, administrative distance compares sources; static AD 1 is preferred to OSPF AD 110.
Incorrect Answers
B:Unequal administrative distances do not normally produce equal-cost installed multipaths.
C:An OSPF metric is not compared with static AD to choose between different route sources.
D:An eligible specific route does not depend on having an unrelated default route.
Question 362
R1 has an OSPF path for 10.80.0.0/16 at AD 110 and a floating static candidate for that exact prefix at AD 200. OSPF is healthy. Which behavior is expected?
- The AD 200 static route supersedes OSPF
- The router ignores the /16 because it is private IPv4 space
- OSPF stays installed and the floating static candidate remains standby
- Both routes must appear as equal-cost forwarding entries
Explanation
Correct Answer
C:The lower-distance OSPF source wins the same prefix while available; AD 200 is a deliberate backup.
Incorrect Answers
A:Higher administrative distance is less preferred for the same destination prefix.
B:Private addressing does not prevent a router from installing valid private-network routes.
D:Different route source distances preclude an automatic ECMP tie.
Question 363
The FIB contains a static 172.20.0.0/16 path and an OSPF 172.20.44.0/24 path. A packet is for 172.20.44.19. What wins the forwarding lookup?
- The static /16 because static distance is ordinarily 1
- A default route because the destination is inside RFC1918 space
- The installed OSPF /24 route
- The route with the lower OSPF cost in another subnet
Explanation
Correct Answer
C:A matching /24 is more specific than /16, regardless of the static source having a smaller AD for a different prefix.
Incorrect Answers
A:AD compares competing sources for an identical prefix at route installation, not different-length forwarding matches.
B:An installed more-specific route is chosen ahead of /0, including for RFC1918 destinations.
D:Metrics of unrelated prefixes do not supersede the destination’s longest match.
Question 364
Two valid OSPF intra-area routes to 10.9.70.0/24 have the same route type and administrative distance, but path costs 35 and 20. Which path is preferred?
- Both paths simply because both use OSPF
- The path with the higher next-hop IPv4 address
- The path with OSPF cost 35
- The path with OSPF cost 20
Explanation
Correct Answer
D:Within the same OSPF route type and prefix, a lower accumulated OSPF cost is preferred.
Incorrect Answers
A:OSPF does not automatically equal-cost load share across unequal metrics.
B:Next-hop numeric ordering is not the OSPF path preference mechanism.
C:A larger OSPF metric represents a less preferred path under these equal-source assumptions.
Question 365
An IOS static route points to 203.0.113.9, but the current routing table has no valid way to reach that next-hop and no usable default route. What happens to the candidate?
- The router forwards blindly out the first physical port
- It cannot be installed as a usable resolved static route
- It becomes an ECMP route with any OSPF entry
- It is always installed because static routes use AD 1
Explanation
Correct Answer
B:The recursive next hop needs an existing valid route or directly connected adjacency for installation.
Incorrect Answers
A:A next-hop-only static route must resolve to a real egress path.
C:Lack of recursion cannot be solved by unrelated ECMP entries.
D:A low administrative distance does not waive next-hop reachability.
Question 366
A router has installed 192.0.2.0/24 via A, 192.0.2.32/27 via B and 192.0.2.48/28 via C. Which next hop is selected for 192.0.2.36?
- A, the /24 route
- None because the destination is in a documentation prefix
- B, the /27 route
- C, the /28 route
Explanation
Correct Answer
C:The destination .36 matches /24 and .32/27 but not .48/28; the /27 is the longest valid match.
Incorrect Answers
A:The /24 match is less specific than the installed matching /27.
B:Documentation addresses are valid for a conceptual forwarding-table exercise; the matching route logic remains applicable.
D:The /28 covers .48–.63 and does not contain destination .36.
Question 367
An IPv4 datagram reaches a transit router with TTL value 1. An otherwise valid matching route exists. What should the router do with the datagram?
- Forward it with TTL 255 after resetting the header
- Discard it when the TTL expires and ordinarily send ICMP Time Exceeded
- Send it only if OSPF administrative distance is low
- Forward it unchanged to preserve the sender hop count
Explanation
Correct Answer
B:A forwarding hop decrements TTL; a resulting zero prevents forwarding and normally triggers Time Exceeded.
Incorrect Answers
A:Routers do not reset an expired packet hop limit as part of normal forwarding.
C:TTL expiry is independent of which protocol installed the matching route.
D:Transit routers must decrement IPv4 TTL rather than preserve the incoming value.
Question 368
An IPv4 router forwards a packet toward a remote network through an Ethernet next hop 10.1.1.2. Which link-layer destination does it normally resolve by ARP on the outgoing LAN?
- The MAC address of the local next-hop 10.1.1.2
- The remote application server MAC several hops away
- The source workstation MAC learned on an ingress port
- The OSPF multicast destination MAC regardless of packet type
Explanation
Correct Answer
A:For routed Ethernet forwarding, ARP resolves the on-link next-hop IPv4 address, not the ultimate remote host.
Incorrect Answers
B:Ethernet framing is hop-local; the remote host MAC is not resolved across intermediate routers.
C:That MAC belongs to the previous link, not the new next-hop Ethernet frame.
D:Normal unicast forwarding toward a next hop does not use OSPF control-plane multicast framing.
Question 369
Two equal-cost OSPF paths to exactly the same /24 are installed with resolvable next hops. Which forwarding capability can distribute traffic across them?
- Equal-cost multipath (ECMP)
- A floating static route with AD 200
- Only DNS round-robin on the application server
- A more-specific /25 route to an unrelated subnet
Explanation
Correct Answer
A:When supported and installed, multiple equal-cost next hops may be used for forwarding, often with a deterministic per-flow hash.
Incorrect Answers
B:A higher-distance standby route is not itself an equal-cost installed OSPF next hop.
C:DNS does not replace the router’s equal-cost forwarding mechanism.
D:That does not create sharing across the two installed equal-prefix OSPF paths.
Question 370
A router receives a packet for 198.51.100.9 and has neither a matching network route nor a default route. What is the correct forwarding disposition?
- ARP for the remote destination on all links
- Forward it through the numerically lowest IP interface
- Drop the packet and send an unreachable indication when appropriate
- Flood the packet from every Ethernet interface
Explanation
Correct Answer
C:Without an installed matching route, the router has no next hop for ordinary IP forwarding.
Incorrect Answers
A:ARP resolves local-link adjacencies and cannot discover routes to arbitrary remote networks.
B:Interface address ordering does not select a default path when no route exists.
D:Layer 3 forwarding does not use Ethernet-style flooding for unknown IP destinations.
