1. How do 802.1w and 802.1D handle BPDUs?

The 802.1w bridge only forwards BPDU packet received from the root bridge.

The 802.1D bridge does not forward BPDU packet.

The 802.1D bridge only forwards BPDU packet received from the root bridge.

The 802.1W bridge does not forward BPDU packet.

2. What are the differences between traffic policing and traffic shaping? (Multiple Choice)

For traffic shaping, the router will buffer excess packets until the bandwidth is available again.

For traffic policing, you can adjust the usage of the cache for traffic exceeding CIR.

For traffic shaping, you can adjust the usage of the buffer for traffic exceeding CIR.

Apply traffic shaping in the direction of the entrance and use traffic policing in the direction of the exit.

Traffic policing uses the token bucket algorithm, and traffic shaping uses the SPD algorithm.

3. Which control bit in the TCP header information can cause the receiver to reset the TCP connection?

SND

ACK

CLR

RST

PSH

SYN

4. The fields indicating priority in the VLAN (802.1Q) data encapsulation are a total of 6 bits.

True

False

5. What are the common methods of learning routes in BGP? (Multiple Choice)

Introducing direct route

Introducing static route

Introducing BGP routes of other AS

Receive neighbor routing information

6. Which AS_PATH can the command ip as-path-filter1 permit^12*74$ match?

AS PATH(321122374)

AS PATH(1236217432374)

AS PATH(1253287423)

AS PATH(32127423)

7. Which descriptions are correct about the BGP reflector? (Multiple Choice)

IBGP neighbor relationships need to be fully interconnected without a route reflector. The introduction of route reflectors can reduce the requirements for full interconnection

The route reflector can advertise the routes learned from the non-client to all clients.

The route reflector can advertise other clients and non-clients from the routes learned from one client.

The route reflector can advertise all clients and non-clients from routes learned from IBGP neighbors.

8. MPLS BGP VPN is a Layer 3 VPN technology used to provide VPN solutions (PPVPN).

What are the basic components of MPLS BGP VPN?

CE and P

PE, P and CE

P and PE

9. In RSTP, which port can provide the backup path to reach the root node of the spanning tree? What status is the port in?

Root port and Listening status

Alternate port and Forwarding status

Alternate port and Learning status

Designated port and Listening status

Alternate port and Discarding status

10. If a switch runs RSTP, which interface on the switch will send BPDU carrying the Proposa logo?

The specified port in the forwarding state

Designated port in non-forwarded state

Root port in the Blocking state

Alternate port
