Which statements correctly describe a directly connected route?Select all correct answers.It normally does not require a remote next-hop router for that connected networkIt represents a network attached to a router interfaceIt must always be manually configured with an ip route commandIt is learned from DNSIt can appear when an interface has a valid IP configuration and is operationalRouting FundamentalsMedium1 mark(s)4. A router has neither a matching specific route nor a usable default route for an IPv4 destination. Which outcomes are possible?Select all correct answers.An ICMP Destination Unreachable message may be generated depending on conditions and policyThe router automatically invents a next hopThe router converts the packet into an ARP broadcast across every interfaceThe router can drop the packetTroubleshooting should include checking the routing tableRouting FundamentalsEasy1 mark(s)5. Which are examples of dynamic routing protocols?Select all correct answers.DHCPARPRIPBGPOSPFRouting FundamentalsEasy1 mark(s)6. Which information can commonly appear in an IPv4 routing table?Select all correct answers.Ethernet FCS valueNext-hop addressOutgoing interfaceDNS MX preferenceDestination network or prefixRouting FundamentalsMedium1 mark(s)7. Which statements describe what normally happens when a router forwards an IPv4 packet over Ethernet?Select all correct answers.The original source and destination Ethernet MAC addresses remain unchanged across every routerIt creates a new Layer 2 frame for the outgoing Ethernet linkThe router replaces the destination IP with its own address during normal routingIt removes or processes the incoming Layer 2 frameIt makes a Layer 3 forwarding decisionRouting FundamentalsMedium1 mark(s)8. A routing table contains 10.0.0.0/8, 10.10.0.0/16, and 10.10.20.0/24. Which routes match destination 10.10.20.50?Select all correct answers.10.10.0.0/1610.10.20.0/24192.168.1.0/2410.0.0.0/80.0.0.0/0 only if no matching route existsRouting FundamentalsMedium1 mark(s)9. Which statements correctly describe route summarization?Select all correct answers.It can represent multiple more-specific networks with a shorter aggregate prefixIt converts IPv4 addresses into MAC addressesIt always makes every route more specificIt can reduce the amount of routing information advertised in some designsIt can reduce routing-table sizeRouting FundamentalsMedium1 mark(s)10. Which statements correctly describe equal-cost multipath routing (ECMP)?Select all correct answers.Traffic may be distributed across eligible pathsIt can allow multiple equal-cost paths toward the same destination prefixIt requires all destinations to use the default routeIts exact behavior depends on the routing platform and configurationIt means every packet is broadcast on every router interfaceRouting FundamentalsEasy1 mark(s)11. Which statements correctly describe dynamic routing protocols?Select all correct answers.They exchange or learn network reachability informationThey can adapt to topology changesThey operate by changing DNS A recordsThey eliminate all routing loops under every possible conditionThey can reduce manual route configuration in larger networksRouting FundamentalsEasy1 mark(s)12. Which statements correctly describe a default route?Select all correct answers.It represents only the local loopback networkIPv4 default route is represented as 0.0.0.0/0It is used when no more-specific matching route is availableIt always overrides every specific routeIt can point toward an upstream routerRouting FundamentalsHard1 mark(s)13. Which checks are useful when troubleshooting routing?Select all correct answers.Inspect routing tables along the pathAssume ping failure always means DNS is brokenVerify next-hop reachability and relevant interface stateVerify source and destination IP addresses and subnet masksChange VLAN IDs randomly before examining the route pathRouting FundamentalsEasy1 mark(s)14. Which statements correctly describe a next hop?Select all correct answers.It is the next Layer 3 device toward a destinationA router may resolve the next hop to a Layer 2 address on an Ethernet linkIt is the TCP destination portIt must always be the final destination hostA static route can specify a next-hop IP addressRouting FundamentalsMedium1 mark(s)15. For destination 10.10.20.50, which route would normally be preferred among these matching entries?Select all correct answers.10.0.0.0/8 because /8 is numerically smaller10.10.20.0/24 over 10.10.0.0/1610.10.20.0/24 because it has the longest matching prefix10.10.20.0/24 over 10.0.0.0/80.0.0.0/0 because default routes always have priorityRouting FundamentalsHard1 mark(s)16. Which conditions can cause a route to be absent from the active routing table?Select all correct answers.The Ethernet frame uses an FCSA static route's next hop cannot be resolved or considered reachable on some platformsA required interface is downThe DNS hostname has a short TTLA dynamic routing protocol has not learned or installed the routeRouting FundamentalsHard1 mark(s)17. Which symptoms can indicate a routing problem?Select all correct answers.Hosts can communicate within their local subnet but not with remote subnetsA DNS TXT record contains a spelling error and all IP-based routing worksTraceroute stops near a router that lacks expected reachabilityA local keyboard key is brokenA routing table is missing the destination prefix or default routeRouting FundamentalsEasy1 mark(s)18. Which statements about a host's default gateway are correct?Select all correct answers.It must be the destination IP address of every remote packetIt is normally a router or Layer 3 interface reachable on the host's local subnetIt is another name for the DNS serverThe host uses it for destinations considered outside the local subnetThe host may use ARP to learn the gateway's MAC address on EthernetRouting FundamentalsMedium1 mark(s)19. A host 192.168.10.20/24 sends traffic to 192.168.20.30/24. Which statements are normally correct?Select all correct answers.The host sends the frame toward its default gatewayThe source changes the destination IP to the gateway IP merely because routing is neededA router must have suitable reachability information toward the destination networkThe destination is outside the source host's local /24 subnetThe host ARPs directly for the remote host's MAC across all routersRouting FundamentalsEasy1 mark(s)20. Which statements correctly describe IP routing?Select all correct answers.Routers use destination IP information when making forwarding decisionsRouting replaces the need for IP addressesRouting forwards packets between different IP networksA routing table contains network reachability informationRouting normally forwards frames using only destination MAC addresses end to endRouting FundamentalsMedium1 mark(s)21. Which statements about routing metrics are correct?Select all correct answers.Different routing protocols can calculate metrics differentlyEvery routing protocol uses an identical metric formulaA metric can help compare routes learned by the same routing protocolA routing metric is always an Ethernet MAC addressLower metric values are preferred in many protocols, depending on protocol rulesRouting FundamentalsMedium1 mark(s)22. Which are potential advantages of static routing?Select all correct answers.No routing-protocol update traffic is required for the static route itselfAutomatic large-scale topology discoveryAutomatic convergence without additional mechanismsSimple and predictable behavior in small networksAdministrative control over the configured pathRouting FundamentalsEasy1 mark(s)23. A router has no specific route for a destination but has a valid default route. Which statements are normally correct?Select all correct answers.The default route can be selectedThe packet can be forwarded toward the default route's next hopThe default route acts as the least-specific matching routeThe router must always drop the packet because no specific route existsThe router sends a DNS query to determine the routeRouting FundamentalsMedium1 mark(s)24. Which statements correctly describe administrative distance or route preference concepts?Select all correct answers.They can help choose between routes learned from different route sourcesThey are the same as TCP sequence numbersA more trusted route source is normally preferred according to platform-specific preference rulesThey are distinct from a routing protocol's path metricThey determine the DNS TTL of a hostnameRouting FundamentalsEasy1 mark(s)25. Which statements correctly describe a static route?Select all correct answers.It does not inherently require a dynamic routing protocol to learn the routeIt can specify a destination prefix and next hopIt automatically discovers every topology changeIt is created by a DNS resolverIt is manually configured by an administratorPreviousNextSubmit Quiz Related Discover more from SanchitGurukul Subscribe to get the latest posts sent to your email.
