If you have a small Routing Information Protocol (RIP) network of 10 hops, how will RIP prevent routing loops?
  • By implementing a limit on the number of hops allowed in a path
  • It will continue to route traffic on the same path.
  • Each router has complete knowledge of the network topology.
  • Gateway Redundancy ProtocolsNAT
What is the Internet standard MTU? 65,535 bytes 1,522 bytes 1,500 bytes 9,198 bytes
  • Checksum
  • ICMP and ARP
  • 1500 bytes
  • Network layer
ARP (Address Resolution Protocol)
  • A database of records that maps MAC addresses to IP addresses. The ARP table is stored on a computer's hard disk where it is used by the ARP utility to supply the MAC addresses of network nodes, given their IP addresses.
  • A core protocol in the TCP/IP suite that belongs in the Data Link layer of the OSI model. ARP works in conjunction with IPv4 to discover the MAC address of a node on the local network and to maintain a database that maps local IP addresses to MAC addresses.
  • Network layer
  • A number indicating a protocol's reliability, with lower values being given higher priority. This assignment can be changed by a network administrator.
You manage a small stub network that has a router configured with static routing. If the connection to the next hop goes down, what action will the router perform?
  • It will continue to route traffic on the same path.
  • default route
  • By implementing a limit on the number of hops allowed in a path
  • Bandwidth and delay
A router receives a packet with a destination address that is not found within its routing table. The router is configured to send all such packets to a specific next hop address. What is this next hop address called?
  • Network layer
  • default route
  • Gateway of last resort
  • Load balancer
AS (autonomous system)
  • A group of networks, often on the same domain, that are operated by the same organization.
  • Static route
  • A core protocol in the TCP/IP suite that belongs in the Data Link layer of the OSI model. ARP works in conjunction with IPv4 to discover the MAC address of a node on the local network and to maintain a database that maps local IP addresses to MAC addresses.
  • A number indicating a protocol's reliability, with lower values being given higher priority. This assignment can be changed by a network administrator.
