1 CCNA 1 v3.1 Module 10 Review

2 What is the address that is changed when a frame is received at a router interface? MAC address

3 What OSI layer offers reliable, connection-oriented data communication services? transport

4 What IP packet field will prevent endless loops? time-to-live

5 Which processes occur each time a packet is switched from one router interface to another? encapsulation de-encapsulation

6 Which of the following are routed protocols? (Choose three.) IP BGP XNS RIP OSPF DECnet IP BGP XNS RIP OSPF DECnet

7 How would you describe path determination at the network layer? router compares available routing table information to select the best path

8 What do routers use to exchange topological information? routing protocols

9 What are 3 metrics used with routing protocols? delay cost reliability

10 What are 2 link-state routing protocols? OSPF IS-IS

11 What are 3 benefits of subnetting? smaller broadcast domains low-level security provided increased address flexibility

12 Given a host with the IP address and a default subnet mask, to which network does the host belong?

13 A small company has a class C network license and needs to create eight usable subnets, each subnet capable of accommodating at least 14 hosts. What is the appropriate subnet mask?

14 How many bits are available for Class B host IP addresses using the default subnet mask? 16

15 What is true concerning the host bits of the network address and the broadcast address? Host bits of the network address are all equal to 0. Host bits of the broadcast address are all equal to 1.

16 How many usable subnets are created by applying the subnet mask to a Class B network? 254

17 What do you call the process that routers use to determine the subnet network address based upon a given IP address and subnet mask? binary ANDing

18 Switches forward broadcast storms. Switches block broadcasts. Switches handle broadcasts in similar fashion to routers. Routers can be segmented to increase bandwidth. Routers block broadcasts. Routers and switches provide security and bandwidth control to overcome broadcast storms. Switches forward broadcast storms. Switches block broadcasts. Switches handle broadcasts in similar fashion to routers. Routers can be segmented to increase bandwidth. Routers block broadcasts. Routers and switches provide security and bandwidth control to overcome broadcast storms. Which statements describe the effects broadcast storms have on networking equipment? (Choose two.)

19 Protocol types Encapsulations Metrics MAC addresses Inbound interfaces Outbound interfaces What information is listed in routing tables? (Choose three.) Protocol types Encapsulations Metrics MAC addresses Inbound interfaces Outbound interfaces

20 What is the routing metric for RIPv1? hop

21 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. Which statements describe Layer 2 and Layer 3 packet address changes as the packet traverses from router to router? (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.

22 What are two differences between routers and switches? Routers make forwarding decisions using IP addresses, but switches use MAC addresses. Switches forward broadcasts and routers do not.

23 What are two functions of a routing protocol? provides processes for sharing route information allows a router to communicate with other routers

24 How many usable class C subnetworks are created with a subnet mask of ? 14

25 Company XYZ uses a network address of It uses the mask of to create subnets. What is the maximum number of usable hosts in each subnet? 62

26 Which are the network and broadcast addresses when given an IP host address of /27? Network = Broadcast =
