CISCO NetAcad CCNA 1 Chapter 6 Exam
Which two pieces of information are in the RAM of a Cisco router during normal operations? (Choose two.)
Cisco IOS IP routing table
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.
Following the 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.
What IPv4 header field identifies the upper layer protocol carried in the packet?
Protocol
Match the command with the devie mode at which the command is entered. (Not all options are used.)
R1(config)# - service password-encryption R1> - enable R1(config-router)# - none R1# - copy running-config startup-config R1(config-line)# - login R1(config-if)# - ip address 192.168.4.4 255.255.255.0
Refer to the exhibit. 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
A router boots and enters setup mode. What is the reason for this?
The configuration file is missing from NVRAM.
Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly
Time-to-Live
What are two types of router interfaces?
WAN LAN
What type of route is indicated by the code C in an IPv4 routing table on a Cisco router?
directly connected route
What is one advantage that the IPv6 simplified header offers over IPv4?
efficient packet handling
What three commands are used to set up secure access to a router through a connection to the console interface? (Choose three.)
login line console 0 password cisco
What are two characteristics of IP? (Choose two.)
operates independently of the network media does not require a dedicated end-to-end connection
What routing table entry has a next hop address associated with a destination network?
remote routes
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
Refer to the exhibit. Which route from the PC1 routing table will be used to reach PC2?
Network Destination: 192.168.10.0 Netmask: 255.255.255.0 Gateway: On-link Interface: 192.168.10.10 Metric 281
The PT initialization was skipped. You will not be able to view the PT activity. Open the PT Activity. The enable password on SW1 is cisco. Perform the tasks in the activity instructions and then answer the question. For what reason is the failure occurring?
SW1 does not have a default gateway configured.
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.
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
