NEW QUESTION 113
The XYZ company network is shown in the figure.

NEW QUESTION 114

132.119.100.0

132.119.100.193

NEW QUESTION 115
In the switching network shown in the figure, all switches have enabled the STP protocol.

SWA was selected as the root bridge. According to the information in the figure, the ______ port should be set to the Blocking state

P1 of SWB

P2 of SWB

P1 of SWC

P2 of SWC

Insufficient information, unable to judge

NEW QUESTION 116
The correct statement about STP, RSTP and MSTP is ______. (Multiple choice)

RSTP is an optimized version of the STP protocol. The delay for the port to enter the forwarding state is greatly shortened under certain conditions, which shortens the time required for the network to finally reach topological stability.

MSTP cannot converge quickly. When the network topology changes, the originally blocked port needs to wait for a period of time before it becomes the forwarding state.

MSTP is compatible with RSTP, but not compatible with STP.

MSTP can make up for the shortcomings of STP and RSTP. It can not only converge quickly, but also enable the traffic of different VLANs to be forwarded along their respective paths, thereby providing a better load sharing mechanism for redundant links.

NEW QUESTION 117

NEW QUESTION 119
The Ethernet port Ethernet0/0 of router MSR-1 is configured as follows:
interface Ethernet0/0
ip address 192.168.0.1 255.255.255.0
A three-layer switch is connected to this interface, and this three-layer switch is the default gateway of multiple network segments of the customer’s office network. For security reasons, the customer now requires configuration on the interface Ethernet0/0 of MSR-1 ACL (does not restrict the application direction) to prohibit all users on the office network from pinging 192.168.0.1, which of the following configurations can be used? (multiple choice)

acl number 3000 rule 0 deny icmp destination 192.168.0.1 0 icmp-type echo-reply

acl number 3000 rule 0 deny icmp destination 192.168.0.1 0 icmp-type echo

acl number 3000 rule 0 deny icmp destination 192.168.0.1 0

acl number 3000 rule 0 deny ip destination 192.168.0.1 0 eq icmp

NEW QUESTION 120
The Layer 2 Ethernet switch searches the MAC address table for an entry that matches the destination MAC address of the frame, thereby forwarding the frame from the corresponding interface. If the search fails, the switch will ______.

discard the frame

Send the frame from all other ports except the incoming port

Find fast forwarding table

Find routing table

NEW QUESTION 121
The two empty-configured routers MSR-1 and MSR-2 are connected as follows: HostA—-GE0/0–MSR-1–S1/0———S1/0– MSR-2–GE0/0—-HostB
The WAN interconnection network segment of the two routers is 192.168.10.0/30, and the GE0/0 address of MSR-1 is 172.16.1.1/24.
After configuration, HostA can ping through 172.16.1.1, and the WAN between the two routers is also interoperable.
Now the following configuration is added to MSR-1:
[MSR-1]rip
[MSR-1-rip-1]network 192.168.10.1
[MSR-1-rip-1]network 172.16.1.1
And started the RIP process on MSR-2.
Which of the following configurations must be done on the MSR-2 to ensure that the MSR-2 learns the RIP route? (multiple choice)

[MSR-2-rip-1]network 192.168.10.1

[MSR-2-rip-1]network 0.0.0.0

[MSR-2-rip-1]network *.*.*.*, where *.*.*.* is any IP address

[MSR-2-rip-1]network *.*.*.*, where *.*.*.* is any IP address on MSR-2

NEW QUESTION 122
It is required to set a subnet mask to divide a class B network 172.16.0.0 into as many subnets as possible. Each subnet requires 500 hosts, so the subnet mask should be _____. (Dotted decimal format) slightly

NEW QUESTION 123
There are two hops from the source device to the destination device. Use the tracert command to detect the path. When detecting the first hop, the source device sends a UDP packet with a TTL of 1 to the middle hop; when detecting the second hop, the source device sends a UDP packet with a TTL of 2, and the packet reaches the middle hop first, and the TTL is decremented When the message reaches the destination, the TTL will be decremented to 0. At this time, the destination device will send an ICMP_____ message to the source to inform the source device that it has tracked the destination address.

Time Exceeded

Echo Request

Echo Reply

Port Unreachable

NEW QUESTION 124

The following statement about the functions of each layer of the OSI reference model is wrong.

The physical layer refers to the original bit stream transmitted on the communication channel (Channel), which defines the mechanical and electrical functions and procedures required for data transmission.

The basic function of the transport layer is to establish and maintain virtual circuits, perform error checking and flow control.

The session layer is responsible for data format processing, data encryption, etc.

The application layer is responsible for providing network services for applications.
