- 1Characteristics of a networkTopology, Speed, Cost, Scalability, Availability, Security, and Reliability
- 2T or F: Communication between networks would be possible without a router determining the best path to the destination and forwarding traffic to the next router along that path.FALSE
- 3T or F: The router is responsible for the routing of traffic between networks.TRUE
- 4It is essentially a specialized computer.Router
- 5T or F: Routers have specialized ports and network interface cards to interconnect devices to other networks.TRUE
- 6T or F: A router connects multiple networks, which means that it has multiple interfaces that each belong to a different IP network.TRUE
- 7What are the primary functions of a router?Determine the best path to send packets and forward packets toward their destination.
- 8The router uses its ____ to determine the best path to use to forward a packet.Routing Table
- 9Routers use ___ and ___ to learn about remote networks and build their routing tables.Static routes and Dynamic routing protocols
- 10When a packet arrives on an interface, it is forwarded to the control plane where the CPU matches the destination address with an entry in its routing table, and then determines the exit interface and forwards the packet.Process Switching
- 11This is a common packet forwarding mechanism which uses a fast-switching cache to store next-hop information.Fast Switching
- 12Like fast switching, ___ builds a Forwarding Information Base (FIB), and an adjacency table.Cisco Express Forwarding (CEF)
- 13The ___ contains pre-computed reverse lookups, next hop information for routes including the interface and Layer 2 information.Forwarding Information Base (FIB)
- 14Identifies a unique host on a local network.IP address
- 15Identifies with which network subnet the host can communicate.Subnet mask
- 16Identifies the router to send a packet to when the destination is not on the same local network subnet.Default gateway
- 17A host can be assigned IP address information either ___ or ___.Statically and Dynamically
- 18The host is manually assigned the correct IP address, subnet mask, and default gateway.Statically
- 19IP address information is provided by a server using the Dynamic Host Configuration Protocol (DHCP).Dynamically
- 20The ___ provides a valid IP address subnet mask, and default gateway for end devices.DHCP server
- 211 blink + pause indicates a port operating at ___ Mb/s.10 Mb/s
- 222 blink + pause indicates a port operating at ___ Mb/s.100 Mb/s
- 233 blink + pause indicates a port operating at ___ Mb/s.1000 Mb/s
- 24Network infrastructure devices require IP addresses to enable ____.Remote management
- 25Using the device ____, the network administrator can remotely connect to the device using Telnet, SSH, HTTP, or HTTPS.IP address
- 26____ support LANs and, therefore, have multiple FastEthernet or Gigabit Ethernet ports.Layer 2 switches
- 27____ support LANs and WANs and can interconnect different types of networks; therefore, they support many types of interfaces.Routers
- 28At a minimum, an IPv6 device must have an ___ but will most likely also have an IPv6 global unicast address.IPv6 link-local address
- 29The ___ interface command is used to automatically create an IPv6 link-local address whether or not an IPv6 global unicast address has been assigned.ipv6 enable
- 30The ___ is a logical interface internal to the router. It is not assigned to a physical port and can therefore never be connected to any other device.Loopback interface
- 31By default, command history is enabled and the system captures the last ___ command lines in its history buffer.10
- 32T or F: A key responsibility of the switching function is to encapsulate packets in the appropriate data link frame type for the outgoing data link.TRUE
- 33If there is a default route, the packet is forwarded to the ___.Gateway of Last Resort
- 34T or F: The best path to a network is the path with the lowest metric.TRUE
- 35A ___ is the quantitative value used to measure the distance to a given network.Metric
- 36Which metric/s does the Routing Information Protocol (RIP) use?Hop count
- 37Which metric/s does the Open Shortest Path First (OSPF) use?Cost based on cumulative bandwidth
- 38Which metric/s does the Enhanced Interior Gateway Routing Protocol (EIGRP) use?Bandwidth, Delay, Load, and Reliability
- 39The ___ represents the "trustworthiness" of the route; the lower the ___, the more trustworthy the route source.Administrative Distance (AD)
- 40What is the AD of OSPF?110
- 41A routing table is a data file stored in which hardware part of the router?RAM
- 42The ____ specifies the exit point to use when the routing table does not contain a path for the destination network.Default static route
- 43T or F: Routers that use dynamic routing protocols automatically share routing information with other routers and compensate for any topology changes without involving the network administrator.TRUE
