Chapter 6-11 Cisco

The configuration file is missing from NVRAM

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

Protocol

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

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

What are two characteristics of IP? (Choose two.)

WAN and LAN

What are two types of router interfaces? (Choose two.)

Efficient packet handling

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

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

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

Remote routes

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

Locate and load the startup-config file from NVRAM.

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

Directly connected route

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

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

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

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

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

Time-to-Live

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

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

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

Login, line console 0, password cisco

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

IP routing table, Cisco IOS

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