(Choose two.) Layer 3 header is removed and replaced at every Layer 3 device. Layer 2 and Layer 3 addresses do not change when the packet traverse. Layer 3 source and destination addresses do not change when the packet traverse.* Layer 2 frame header and trailer are removed and replaced at every Layer 3 device.* Layer 2 source and destination addresses do not change when the packet travels. 13 Which of the following are benefits of subnetting? (Choose three.) smaller broadcast domains* larger collision domains low-level security provided* fewer broadcast domains increased address flexibility* larger broadcast domains 14 How many bits are available for Class B host IP addresses using the default subnet mask? 1 4 8 14 16* 24 15 Which processes occur each time a packet is switched from one router interface to another? (Choose two.) encapsulation* ARP RARP de-encapsulation* circuit switching FastForward switching 16 What are two functions of a routing protocol? (Choose two.) defines the format and use of the fields within a packet provides processes for sharing route information* allows a router to communicate with other routers* provides address information that allows a router to forward data 17 Which IP packet field will prevent endless loops? type-of-service identification flags time -to-live* header checksum 18 Which statements describe the effect a broadcast storm has on networking equipment? (Choose two.) Switches forward broadcast storms.* By default, routers do not forward broadcast storms.* Switches provide security and bandwidth control to overcome broadcast storms. Routers forward broadcast storms. 19 What do routers use to exchange topological information? protocol styles routing protocols* MAC addresses RARP addresses network topologies 20 Which of the following is the address that is changed when a frame is received at a router interface?

(Choose two.) Routers and switches operate exactly the same. Routers make forwarding decisions using IP addresses, but switches use MAC addresses.* Routers forward broadcasts and switches do not. Switches forward broadcasts and routers do not.* Routers operate faster than switches. Switches provide more security than routers. 23 What information is listed in routing tables? (Choose three.) protocol types* encapsulations metrics* MAC addresses inbound interfaces outbound interfaces* 24 Which of the following OSI layers offers reliable, connection-oriented data communication services? session transport* network data link 25 Given a host with the IP address 172.32.65.13 and a default subnet mask, to which network does the host belong? 172.32.65.0 172.32.65.32 172.32.0.0* 172.32.32.0 26 How many usable class C subnetworks are created with a subnet mask of 255.255.255.224? 1 2 3 4 5 6
