Which characteristics of the network class in the OSI model permits carrying packets for multiple species of communications among many hosts?

the de-encapsulation that headers from lower layersthe selection of paths for and also direct packets towards the destinationthe capability to operate without regard come the data that is lugged in each packetthe ability to manage the data transport between processes to run on hosts
The role of the network class protocols states the packet structure and also processing supplied to carry the data indigenous one organize to one more host. The actual communication data is encapsulated in the network layer PDU. The feature of its procedure without regard come the data lugged in every packet permits the network great to carry packets for multiple types of communications.

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

does not need a committed end-to-end link operates individually of the network mediaretransmits packets if errors occurre-assembles out of bespeak packets into the exactly order at the recipient endguarantees shipment of packets
The internet Protocol (IP) is a connectionless, finest effort protocol. This way that IP calls for no end-to-end link nor does it guarantee shipment of packets. IP is likewise media independent, which method it operates individually of the network media delivering the packets.

When a connectionless protocol is in use at a reduced layer that the OSI model, how is lacking data detected and retransmitted if necessary?

Connectionless acknowledgements are provided to inquiry retransmission.Upper-layer connection-oriented protocols store track the the data received and can request retransmission native the upper-level protocols ~ above the sending host.Network great IP protocols regulate the interaction sessions if connection-oriented transport services are no available.The best-effort delivery procedure guarantees that all packets that are sent are received.
When connectionless protocols are in use at a lower layer of the OSI model, upper-level protocols may need to work together on the sending and also receiving master to account for and also retransmit lost data. In part cases, this is no necessary, because for some applications a details amount that data loss is tolerable.

Which ar in the IPv4 header is used to avoid a packet native traversing a network endlessly?

Time-to-LiveSequence NumberAcknowledgment NumberDifferentiated Services
The value of the Time-to-Live (TTL) field in the IPv4 header is provided to border the lifetime of a packet. The sending hold sets the early TTL value; which is reduced by one every time the packet is processed by a router. If the TTL ar decrements to zero, the router discards the packet and sends an Internet control Message Protocol (ICMP) Time Exceeded post to the source IP address. The differentiated Services (DS) field is offered to identify the priority of every packet. Succession Number and also Acknowledgment Number are two areas in the TCP header.

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

ProtocolIdentificationVersionDifferentiated Services
It is the Protocol field in the IP header the identifies the upper-layer protocol the packet is carrying. The Version ar identifies the IP version. The Differential Services ar is provided for setting packet priority. The Identification ar is provided to reorder broke up packets.

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

smaller-sized headerlittle necessity for handling checksumssmaller-sized source and location IP addressesefficient packet handling
 The IPv6 simplified header offers several advantages over IPv4:· far better routing efficiency and efficient packet taking care of for performance and forwarding-rate scalability· No necessity for handling checksums· simplified and more efficient extension header mechanisms (as opposed to the IPv4 options field)· A circulation Label field for per-flow processing with no must open the move inner packet to identify the assorted traffic flows

If a path in the routing table points come a following hop address, the router will perform a 2nd lookup to determine out which user interface the next hop is located.

What form of course is suggested by the password C in an IPv4 routing table top top a Cisco router?

static routedefault routedirectly associated routedynamic path that is learned with EIGRP

 Some of the IPv4 routing table codes encompass the following:

C – straight connectedS – staticD – EIGRP* – candidate default

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

directly-connected routeslocal routesremote routesC and L resource routes
Routing table entries because that remote courses will have a next hop IP address. The next hop IP attend to is the attend to of the router user interface of the next an equipment to be offered to reach the destination network. Directly-connected and also local routes have no next hop, because they execute not require going through one more router to it is in reached.

Which statement defines a hardware function of a Cisco 1941 router that has the default hardware configuration?

It go not have actually an AUX port.It has actually three FastEthernet interfaces because that LAN access.It has actually two types of harbor that deserve to be offered to accessibility the console.It go not require a CPU since it relies on Compact speed to operation the IOS.
The connections in a Cisco 1941 router include two varieties of ports that are provided for early configuration and also command-line user interface management access. The 2 ports space the regular RJ-45 port and a new USB Type-B (mini-B USB) connector. In addition, the router has actually an AUX harbor for remote management access, and also two Gigabit Ethernet interfaces because that LAN access. Compact Flash have the right to be used increase machine storage, but it does not execute the attributes of the CPU, which is required for procedure of the device.

Following default settings, what is the next step in the router boots sequence ~ the IOS tons from flash?

Perform the short article routine.Locate and also load the startup-config paper from NVRAM.Load the bootstrap regime from ROM.Load the running-config document from RAM.

 There room three major steps to the router boot sequence:

Perform Power-On-Self-Test (POST)Load the IOS from speed or TFTP serverLoad the startup configuration file from NVRAM
 Router interfaces deserve to be grouped into two categories:· LAN interfaces – offered for connecting cables the terminate v LAN devices, such as computers and also switches. This interface can also be used to attach routers to each other.· WAN interfaces – provided for connecting routers to external networks, generally over a bigger geographical distance.

Which 2 pieces of details are in the lamb of a Cisco router during normal operation? (Choose two.)

Cisco IOSbackup IOS fileIP routing tablebasic diagnostic softwarestartup configuration file
The Cisco IOS file is save in flash memory and copied into RAM throughout the boot up. The IP routing table is likewise stored in RAM. The simple diagnostic software application is save on computer in ROM and also the startup configuration file is save in NVRAM.

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

The IOS picture is corrupt.Cisco IOS is lacking from flash memory.The configuration file is lacking from NVRAM.The POST process has recognize hardware failure.
The startup configuration record is stored in NVRAM and also contains the regulates needed to at first configure a router. It also creates the running configuration paper that is save in in RAM.

What is the objective of the startup configuration document on a Cisco router?

to facilitate the an easy operation that the hardware contents of a deviceto save on computer the regulates that are offered to at first configure a router top top startupto save on computer the configuration commands that the router IOS is currently usingto carry out a minimal backup variation of the IOS, in instance the router cannot load the full featured IOS
The startup configuration record is save in NVRAM and contains the regulates needed to initially configure a router. It additionally creates the running configuration document that is stored in in RAM.

Which three commands are provided to set up secure accessibility to a router with a connection to the console interface? (Choose three.)

interface fastethernet 0/0line vty 0 4line console 0enable mystery ciscologin password cisco
 The three commands needed to password protect the console port space as follows:line console 0password ciscologin The interface fastethernet 0/0 command is generally used to accessibility the configuration mode used to apply details parameters such as the IP attend to to the Fa0/0 port. The line vty 0 4 command is provided to access the configuration mode for Telnet. The 0 and 4 parameters specify harbor 0 v 4, or a best of five simultaneous Telnet connections. The enable secret command is supplied to apply a password provided on the router to access the privileged mode.

Which characteristic describes an IPv6 improvement over IPv4?

IPv6 addresses are based upon 128-bit flat addressing as opposed to IPv4 i m sorry is based upon 32-bit hierarchical addressing.The IPv6 header is less complicated than the IPv4 header is, which boosts packet handling.Both IPv4 and also IPv6 support authentication, however only IPv6 supports privacy capabilities.The IPv6 address space is four times bigger 보다 the IPv4 address space.
IPv6 addresses are based upon 128-bit ordered addressing, and also the IPv6 header has been simplified with fewer fields, improving packet handling. IPv6 natively supports authentication and privacy capabilities together opposed to IPv4 the needs added features to support those. The IPv6 address an are is plenty of times bigger 보다 IPv4 deal with space.

Open the PT Activity. The permit password top top all tools is cisco.Perform the jobs in the activity instructions and then answer the question.

For what reason is the failure occurring?

PC1 has actually an incorrect default gateway configured.SW1 walk not have a default gateway configured.The IP attend to of SW1 is configured in a dorn subnet.PC2 has an not correct default gateway configured.
The ip default-gateway command is lacking on the SW1 configuration. Packets from PC2 room able to effectively reach SW1, yet SW1 is unable to forward reply packets beyond the local network there is no the ip default-gateway command issued.
