Cisco Chapter 6 Exam

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

Which characteristic describes an IPv6 enhancement over IPv4? - IPv6 addresses are based on 128-bit flat addressing as opposed to IPv4 which is based on 32-bit hierarchical addressing. - The IPv6 header is simpler than the IPv4 header is, which improves packet handling. - Both IPv4 and IPv6 support authentication, but only IPv6 supports privacy capabilities. - The IPv6 address space is four times bigger than the IPv4 address space.

What is one advantage that the IPv6 simplified header offers over IPv4? -smaller-sized header -little requirement for processing checksums -smaller-sized source and destination IP addresses -efficient packet handling

What routing table entry has a next hop address associated with a destination network? - directly-connected routes - local routes - remote routes - C and L source routes

What are two types of route interfaces? - SVI - LAN - DHCP - Telnet - WAN

Which three commands are used to set up secure access to a router through a connection to the console interface? - interface fastethernet 0/0 - line vty 0 4 - line console 0 - enable secret cisco - login - password cisco

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? - FastEthernet0/0 - FastEthernet0/1 - Serial0/0/0 - Serial0/0/1

A router boots and enters setup mode. What is the reason for this? - The IOS image is corrupt. - Cisco IOS is missing from flash memory. - The configuration file is missing from NVRAM. - The POST process has detected hardware failure.

Following default settings, what is the next step in the router boot sequence after the IOS loads from flash? - Perform the POST routine. - Locate and load the startup-config file from NVRAM. - Load the bootstrap program from ROM. - Load the running-config file from RAM.

For what reason is the failure occurring? - PC1 has an incorrect default gateway configured. - SW1 does not have a default gateway configured. - The IP address of SW1 is configured in a wrong subnet. - PC2 has an incorrect default gateway configured.

What is the purpose of the startup configuration file on a Cisco router? - to facilitate the basic operation of the hardware components of a device - to contain the commands that are used to initially configure a router on startup - to contain the configuration commands that the router IOS is currently using - to provide a limited backup version of the IOS, in case the router cannot load the full featured IOS

What type of route is indicated by the code C in an IPv4 routing table on a Cisco router? - static route - default route - directly connected route - dynamic route that is learned through EIGRP

Which statement describes a hardware feature of a Cisco 1941 router that has the default hardware configuration? - It does not have an AUX port. - It has three FastEthernet interfaces for LAN access. - It has two types of ports that can be used to access the console. - It does not require a CPU because it relies on Compact Flash to run the IOS.

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary? - Connectionless acknowledgements are used to request retransmission. - Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host. - Network layer IP protocols manage the communication sessions if connection-oriented transport services are not available. - The best-effort delivery process guarantees that all packets that are sent are received.

Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly? - Time-to-Live - Sequence Number - Acknowledgment Number - Differentiated Services

What IPv4 header field identifies the upper layer protocol carried in the packet? - Protocol - Identification - Version - Differentiated Services

What are two characteristics of IP? (Choose two.) - does not require a dedicated end-to-end connection - operates independently of the network media - retransmits packets if errors occur - re-assembles out of order packets into the correct order at the receiver end - guarantees delivery of packets

Which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts? - the de-encapsulation of headers from lower layers - the selection of paths for and direct packets toward the destination - the ability to operate without regard to the data that is carried in each packet - the ability to manage the data transport between processes running on hosts

Which two pieces of information are in the RAM of a Cisco router during normal operation? (Choose two.) - Cisco IOS - backup IOS file - IP routing table - basic diagnostic software - startup configuration file
