NEW QUESTION 26
Which packet type is used by network devices running the SNMPv1 protocol to actively send alarm information? ()

Trap

B. Response

C. Get Request

D. Get-Next Request

NEW QUESTION 27
Which of the following parameters is not used by an Advanced ACL?

Source interface.

Destination port number.

Protocol number.

Time-range.

* Advanced ACLs (3000-3999) allow filtering based on:
* Source and Destination IPs
* Protocol Number (C – Correct)
* Destination Port Number (B – Correct)
* Time-range (D – Correct)
* A (Incorrect): ACLs do not filter based on the source interface, but rather on IPs, ports, and protocols.
Thus, the correct answer is A (Source Interface).

NEW QUESTION 28
Which of the following statements about IPv6 RA. and RS messages are correct? ()

RS is used to reply address prefix information

RS is used to request address prefix information

RA. Used to request address prefix information

RA. Used to reply address prefix information

NEW QUESTION 29
The MAC address table of existing switches is shown in the figure. Which of the following statements are correct? () (Single-choice question)

Received a data frame with a source MAC address of 5489-9811-0b49 and a destination MAC address of 5489-989d1d30 from the port. Forwarded from the Eth0/0/2 port

The data frame with the source MAC address of 5489-9885-18a8 and the destination MAC address of 5489-989d-1d30 is received from the port. It is forwarded from the Eth0/0/1 port

When the switch restarts, the MAC address learned by port Eth0/0/2 does not need to be relearned

NEW QUESTION 30
Which of the following ACLs can match the transport layer port number?

Basic ACL

Layer 2 ACL

Advanced ACL

Intermediate ACL

Explanation:

NEW QUESTION 31
Which of the following statements is true?

Routers work at the physical layer.

Switches work at the network layer.

Switches work at the physical layer.

Routers work at the network layer.

NEW QUESTION 32
What action does an access port take in the process of sending VLAN frames?

The access port sends tagged frames.

The access port strips the VLAN tag and forwards the frame.

The access port exchanges the VLAN tag of the inbound and outbound port of the frame before forwarding the frame.

The access port attaches its PVID information to the frame.

An access port is a switch port assigned to a single VLAN and used to connect end devices (such as PCs or printers).
* Access ports do not send VLAN tags. They remove the VLAN tag before forwarding frames to the connected device because most end devices do not support VLAN tagging.
* Option A (Incorrect): Tagged frames are sent only by trunk ports, not access ports.
* Option B (Correct): The access port strips the VLAN tag before forwarding the frame to ensure compatibility with non-VLAN-aware devices.
* Option C (Incorrect): VLAN tags are not exchanged between inbound and outbound ports.
* Option D (Incorrect): The access port does not attach PVID information to the frame when sending it out.
Thus, the correct answer is B.

NEW QUESTION 33
The following figure shows the routing table of a router. When the router receives a destinationI
When the P address is a data packet of 9.1.1.1,The router will forward according to the route of 9.1.0.0/16 because the mask length of this route is longer. ()(True or False)

True

False

NEW QUESTION 34
Refer to the graphic, which of the following statements is true about OSPF topology and configuration?

Compared with R1, R2 is more likely to become the DR because the DR priority of the interface on R2 is lower than that of R1.

After the default network type of the interface on R1 is restored to broadcast, a stable OSPF neighbor relationship can be set up between R1 and R2.

After the default network type of the interface on R1 is restored to broadcast and the hello packet sending interval is changed to 10s, a stable OSPF neighbor relationship can be set up between R1 and R2.

A stable OSPF neighbor relationship can be set up between R1 and R2.

NEW QUESTION 35
Which of the following IPv6 addresses can be abbreviated as 2FFF DAC:ABEF:CDAA:732? ()

2FFF:ODAC.:ABEF:0000:0000:0000:CDAA4:0732

2FFF:ODAC:ABEF 0000:0000:CDAA:0732

2FFF DACO:ABEF 0000000:0000:CDAA:0732

2FFF:ODAC:ABEF:0000:0000:0000:CDAA:7320

NEW QUESTION 36
Which of the following states indicates that the OSPF neighbor relationship has been established?

Attempt

Down

Full

2-way

Detailed Explanation: In OSPF, the “Full” state signifies that the neighbor relationship has been fully established, with both routers synchronized and their LSDBs updated. This state is achieved after exchanging and acknowledging Link State Advertisements (LSAs) between the neighbors, marking the completion of OSPF adjacency.

NEW QUESTION 37
Which of the following are not the characteristics of a small campus network? ()

Simple network level

Fewer users

Simple network requirements

Wide coverage

NEW QUESTION 38
On the network shown in the figure, HOST A and HOST B are required to communicate with each other across VLANs through one-armed routing. To satisfy this requirement, which of the following commands needs to be performed on G0/0/1.1 of RTA?

dot1q termination vid 20

dot1q termination vid 30

dot1q termination vid 10

dot1q termination vid 1

Understanding the Network Diagram
* Host A is in VLAN 10 with a gateway of 10.0.1.254.
* Host B is in VLAN 20 with a gateway of 10.0.2.254.
* The router (RTA) has two sub-interfaces:
* G0/0/1.1 (10.0.1.254/24) for VLAN 10
* G0/0/1.2 (10.0.2.254/24) for VLAN 20
* The switch (SWA) is using VLAN trunking to forward packets to the router, requiring 802.1Q encapsulation.
* One-Armed Routing (Router-on-a-Stick) is being used, meaning a single physical interface (G0/0/1) handles multiple VLANs using sub-interfaces.
Analyzing the Answer Choices
* Option A (dot1q termination vid 20) # Incorrect
* This command would be configured on G0/0/1.2, not G0/0/1.1.
* Option B (dot1q termination vid 30) # Incorrect
* VLAN 30 is not part of this topology.
* Option C (dot1q termination vid 10) # Correct
* Since G0/0/1.1 corresponds to VLAN 10, the correct command is dot1q termination vid 10.
* Option D (dot1q termination vid 1) # Incorrect
* VLAN 1 is usually the default VLAN, which is not relevant here.
Thus, the correct answer is C (dot1q termination vid 10).
