NEW QUESTION 116
The TCP protocol uses ______ to distinguish different connections.

Port number

Port number and IP address

Port number and MAC address

IP address and MAC address

NEW QUESTION 117
UDP belongs to the ______ of the OSI reference model.

Network layer

Transport layer

Session layer

Presentation layer

NEW QUESTION 118
Use the ______ command to specify the operating system software to be used for the next startup.

startup

boot-loader

bootfile

boot startup

NEW QUESTION 119
The correct statement about STP, RSTP and MSTP is ______. (Multiple choice)

MSTP is compatible with STP and RSTP.

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

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 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 120
Run OSPF between the four MSR routers and divide the area. The connection and division methods are shown in the figure.

It is known that the OSPF Cost value of all links in the network is 10, so the correct description of this figure is ______. (Multiple choice)

All four routers in the network are ABR (Area Border Router)

After the link between Area 0 fails, the path for RTA to access RTB is RTA->RTD->RTC->RTB

There are two equivalent paths for RTA to access RTC, namely RTA->RTB->RTC and RTA->RTD-RTC

RTD access to RTB will give priority to RTD->RTA->RTB path

NEW QUESTION 121
Which of the following protocols may run between a frame relay DTE device and a frame relay switch?

PVC

SVC

DLCI

LMI

NEW QUESTION 122
For the understanding of packet switching, the correct one of the following statements is ______. (Multiple choice)

Packet switching is a switching method based on Store-and-Forward switching

The transmitted information is divided into packets of a certain length and forwarded in units of packets

Each packet carries the address identification of the receiver and the sender, and the packet can be forwarded directly without any operation, thereby improving efficiency

Packet switching includes frame-based packet switching and cell-based packet switching

NEW QUESTION 123
The three MSR routers RTA, RTB, and RTC are connected to the same frame relay network through their respective S1/0 interfaces. This frame relay network can provide enough PVC resources. As a network engineer, you need to assign IP addresses to these frame relay interfaces.
Which of the following statements is incorrect?

If transit through any router is not allowed, at least two IP subnets are required to enable three routers to communicate with each other through this frame relay network

If transit through any router is not allowed, at least three IP subnets are required to realize the two-by-two intercommunication of the three routers through this frame relay network

Under the premise of correct routing configuration, three routers can communicate through this frame relay network without configuring sub-interfaces.

Under the premise of correct routing configuration, three routers can communicate through this frame relay network with only one IP subnet.

NEW QUESTION 124
Xiao L is a senior IP network expert, determined to develop a new dynamic routing protocol. Which of the following should be included in the working process of a routing protocol? (multiple choice) (multiple choice)

Found neighbors

Switch routing

Calculate route

Maintain and update routing

NEW QUESTION 125
To configure Trunk on the link between Ethernet switches and allow the transmission of VLAN 10 and VLAN 20 information, you must configure ______ on the switch.

[Switch-Ethernet0/1] port link-type trunk

[Switch] port link-type trunk

[Switch] port link-type access

[Switch-Ethernet0/1] port trunk pvid 10

NEW QUESTION 126
If a port running STP in the Ethernet switch does not receive or forward data, receives and sends BPDUs, and does not perform address learning, then the port should be in the ______ state.

Blocking

Listening

Learning

Forwarding

Waiting

Disable

NEW QUESTION 127
PPP has to go through a series of negotiation process before establishing the link, the correct negotiation sequence is ___. (Fill in the code of each step one by one, there can be no spaces in between, such as: ABC)

PAP/CHAP

NCP

LCP

NEW QUESTION 128
On the MSR router, use the ______ command to configure the NAT address pool.

nat address-group

nat ip pool

nat net pool

nat pool

NEW QUESTION 129
The RIP routing protocol has a timer, which defines the elapsed time for a route from the metric value to 16 until it is deleted from the routing table, then ______.

This timer is Timeout timer

This timer is Garbage-Collect timer

The timer defaults to 120s on the MSR router

The timer defaults to 180s on the MSR router

NEW QUESTION 130
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
