In the data segment between R2 and the web server, when R2 encapsulates the frame to be sent to the web server, R2 uses the MAC address of the interface directly connected to the data segment Fa0/1 as the source MAC .
The correct answer is: 0001.C972.4202

Sixth question:

What is the role of routing protocols?

Choose one:
●Used to build and maintain ARP table.
●Provide a method of dividing and reorganizing data packets.
●Allows administrators to design network addressing schemes.
●Allow routers to share information about known networks.
●Provide procedures to encode and decode data into bits in order to forward data packets.

Feedback Refer to curriculum topic: 1.3.4 The
correct answer is: Allow routers to share information about known networks.

Question 7:

Which function of the Cisco router allows the forwarding of traffic without a specific route?

Choose one:
●Next hop
●Gateway last choice❤
●Route source
●Outgoing interface

Feedback Refer to curriculum topic: 1.2.2 The
default static route is used as the gateway of last resort to send traffic with an unknown destination address to the next hop/outgoing interface. After the traffic is matched in the router, the next hop or outgoing interface is the destination network of the traffic. The source of the route indicates where the route is learned from.
The correct answer is: the gateway of last resort

Question 8:

When the router learns that multiple paths can reach the destination network of the same routing protocol, which factor will the router consider when choosing the best path for forwarding data packets?

Choose one:
●Minimum metric ❤
●The order of the path in the routing table
●The fastest bandwidth of the sending interface
●The reliability value of the neighbor router

Feedback Refer to curriculum topic: 1.2.2
When the router learns that multiple paths can reach the destination network of the same routing protocol, the route with the lowest metric value will be put into the routing table for forwarding data packets to the network.
The correct answer is: minimum metric

Question 9:

Which two statements can correctly describe router components? (Choose two.)

Choose one or more:
●The configuration files used during the startup process are permanently stored in RAM.
●ROM contains diagnostic operations performed on hardware modules.
●NVRAM stores the IOS backup used during startup.
●The flash memory will not lose its contents during restart.
●ROM contains the latest and most complete version of IOS.
●The flash memory contains the boot system command to confirm the location of the IOS.

Feedback

Refer to curriculum topic: 1.1.1 The router contains four types of memory:

RAM - 易失存储器,用于存储运行 IOS、运行配置文件、路由表、ARP 表,并作为数据包缓冲器
ROM - 非易失存储器,用于保存有限版本的 IOS、启动指令和基本诊断软件
NVRAM - 非易失存储器,用于保存启动配置文件
Flash - 非易失存储器,用于保存 IOS 和其他系统文件

The correct answer is: ROM contains the diagnostic operations performed on the hardware module. , The flash memory will not lose its contents during the restart process.

Question 10:

A new junior network intern connects a laptop to the access layer switch in the wiring closet. After configuring the terminal emulation program, the intern presses the Enter key, and the S1_ATC_E2> prompt appears. What can I do to better protect the switch?

Choose one:
●Create a slogan message.
● Create a console password.
●Use the enable secret command.
● Use the service password-encryption command.

Feedback Refer to curriculum topic: 1.1.3 When
configuring the console line with password, you need to enter the password to access the switch prompt. The banner is just a warning message. The enable secret command encrypts the enable password. When using the show
running-configuration command, the service password-encryption command can protect all passwords against theft.
The correct answer is: Create a console password

Question 11:

Why do I need a router in the network?

Choose one:
●Connect the device to the LAN
●Ensure the transmission of data packets
●Provide data packet transmission status
●Forward network traffic to the remote network ❤
●Route information and accept confirmation of data delivery

Feedback Refer to curriculum topic: 1.1.1
A basic function of routers is to connect different networks. Each interface of the router belongs to a different network. LAN
equipment can be connected through a switch. Data packet delivery, data packet delivery status and confirmation belong to the functions of the transport layer. The correct answer is: forward network traffic to a remote network

Question 12:

Regarding the description of load balancing characteristics, which two are correct? (Choose two.)

Choose one or more:
● Load balancing means that the router sends the same data packet to different destination networks.
●Load balancing refers to sending the same number of data packets through static routing and dynamic routing.
● Load balancing allows the router to send data packets to the same destination network through multiple paths.
●EIGRP supports unequal-cost load balancing.
●If multiple paths to the same destination have different metrics, the router does not support load balancing.

Feedback Refer to curriculum topic: 1.2.2 The
correct answer is: load balancing allows routers to send data packets to the same destination network through multiple paths. , EIGRP supports unequal-cost load balancing

Question 13:

What is the gateway of last resort?

Choose one:
●The IP address of another router❤
The IP address of the Internet provider
●The term describing the default gateway on the host device
●The location where the dropped packets are delivered

Feedback Refer to curriculum topic: 1.1.2 Even though the gateway of last resort may be the IP
address of the ISP router , this is not necessarily the case. As you can see in the Cisco routing table, the "gateway of last resort" is the IP address used to route the packet to a network not explicitly listed in the routing table. Windows-
based computers use the term "default gateway" instead of "gateway of last resort."
The correct answer is: the IP address of the other router

Question 14:

During the encapsulation process, how does the PC determine whether the data packet is directed to a host on the remote network?

Choose one:
● Obtain the MAC address of the destination host by checking the ARP cache
● Obtain the information of the destination host by querying the DNS server
● By sending the broadcast to the local LAN data segment to see if there is any response
● By checking the destination IP address and its Perform AND operation in the subnet mask to confirm

Feedback Refer to curriculum topic: 1.2.1 When the PC needs to encapsulate a frame to send a data packet, it first
performs an AND operation with its own IP address and subnet mask to generate a network address. Then it performs another AND operation using the destination IP address and the same subnet mask. By comparing the
results of two AND operations, the PC can know whether the target is on the local LAN or the remote network.
The correct answer is: Determine by performing an AND operation on the destination IP address and its subnet mask

Question 15:

Insert picture description here

Please refer to the illustration. What is the purpose of the router port shown?

Choose one:
●Backup IOS
●Configure the router❤
●Run IOS from a backup location
●Connect to the port in the switch

Refer to curriculum topic: 1.1.2 The port shown in the figure is a USB port used by some Cisco router models. This USB
port provides console access to the router, allowing access to the CLI for configuration. The light blue background behind the icon is also the standard color used by Cisco devices to indicate console connections.
The correct answer is: configure the router
