Chapter 6 Cisco Netacad study guide

What are two characteristics of IP?

-does not require a dedicated end-to-end connection -operates independently of the network media

Which three commands are used to set up secure access to a router through a connection to the console interface?

-line console 0 -login -password cisco

What is one advantage that the IPv6 simplified header offers over IPv4?

Efficient packet handling

Which two pieces of information are in the RAM of a Cisco router during normal operation?

IP routing table and Cisco IOS

Which statement describes a hardware feature of a Cisco 1941 router that has the default hardware configuration?

It has two types of ports that can be used to access the console

What are two types of router interfaces?

LAN and WAN

Following default settings, what is the next step in the router boot sequence after the IOS loads from flash?

Locate and load the startup-config file from NVRAM.

For what reason is the failure occurring in the PT activity?

SW1 does not have a default gateway configured.

R1 receives a packet destined for the IP address 192.168.2.10. Out which interface will R1 forward the packet?

Serial0/0/1

Which characteristic describes an IPv6 enhancement over IPv4?

The IPv6 header is simpler than the IPv4 header is, which improves packet handling

Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?

Time-to-Live

Which route from the PC1 routing table will be used to reach PC2?

option 3 is the correct answer

What routing table entry has a next hop address associated with a destination network?

remote routes

Which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts?

the ability to operate without regard to the data that is carried in each packet

What is the purpose of the startup configuration file on a Cisco router?

to contain the commands that are used to initially configure a router on startup

What IPv4 header field identifies the upper layer protocol carried in the packet?

Protocol

A router boots and enters setup mode. What is the reason for this?

The configuration file is missing from NVRAM.

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?

Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.

What type of route is indicated by the code C in an IPv4 routing table on a Cisco router?

directly connected route
