RSTP provides different functions in different scenarios. Which of the following statements Is false?

The role of the designated port that is enabled with root protection cannot be changed

After TC-BPDU attack defense function is enabled, you can set the number of times the switch processes TC BPDUs within a certain period

The role of the designated port that is enabled with root protection cannot be changed

If the edge port on the switch enabled with BPDU protection receives RST BPDU, the switch sets the edge port as a non-edge-port and triggers STP calculation

When the designated port enabled with root protection receives optimal RST BPDUs, the port enters the Discarding state and does not forward packets. If the port does not receive optimal RST BPDUs within a certain period of time, the port will automatically restore to the Forwarding state

Compared with STP, RSTP defines the different port states. Which of the following statements regarding discarding and learning states are true?

The port In discarding or learning state does not forward data frames.

The port in discarding state does not learn MAC addresses table.

The port In discarding or learning state does not forward data frames.

The port in discarding state does not learn MAC addresses table.

The port in discarding or learning state does not learn MAC addresses

The port In learning stole docs not learn MAC addresses table.

As shown in the figure, SWA, SWB, SWC, and SWD run the Rapid Spanning Tree Protocol (RSTP). Which of the following statements are true?

After a port is Configured as an edge port, the port can quickly enter the Forwarding state.

You can enable the edge port on SWD's GEO/0/2 connected to the terminal so that this port can quickly enter the Forwarding state.

You can enable the edge port on SWC's GE0/0/2 connected to the terminal so that this port can quickly enter the forwarding state.

Once receiving OPOUs, the edge port re-partlci pates in the calculation of the spanning tree.

After a port is Configured as an edge port, the port can quickly enter the Forwarding state.

You can enable the edge port on SWD's GEO/0/2 connected to the terminal so that this port can quickly enter the Forwarding state.

You can enable the edge port on SWC's GE0/0/2 connected to the terminal so that this port can quickly enter the forwarding state.

Which of the following statements regarding IGMPv1 and IGMPv2 are true?

1GMPv2 defines the Leave message type.

IGMPv1 does not define the IGMP Leave message type.

1GMPv2 supports only general query.

1GMPv2 defines the Leave message type.

IGMPv1 does not define the IGMP Leave message type.

Which of the following statements is false, based on the following IGMP information on an interface of RTA?XC

The interval for sending group-specific Query messages is 60s.

The maximum time for response to Query messages is 10s.

The IP address of the interface is 192.168.1.1.

Which of the following statements about multicast packet forwarding is true?

The source address of a multicast packet is a unicast address.

If a multicast data packet fails the RPF check, the packet must have been received through a sub-optimal interface. However, this interface still receives and forwards the multicast traffic downstream.

IGMP snooping cannot control the scope of multicast traffic flooding on a Layer 2 network.

The source address of a multicast packet is a unicast address.

In multicast transmission, the destination address of a packet can be the unicast address of a host.

Which of the following statements regarding the stateful inspection firewall is true?

The stateful inspection firewall only needs to match the first data packet against a rule, and the subsequent packets of the connection are matched directly in the state table.

When the stateful inspection firewall checks packets, packets of one same connection are not correlated.

Because UDP is a connectionless protocol, so the stateful inspection firewall cannot match UDP packets with the status table.

The stateful inspection firewall only needs to match the first data packet against a rule, and the subsequent packets of the connection are matched directly in the state table.

The stateful inspection firewall needs to match the rules for each incoming packet.

Which of the following statements regarding the firewall zone security level is false?

The configured security level cannot be changed.

Two zones cannot be configured with the same security level.

The default security level of the new zone is 1.

Only the security level of the user-defined zone can be configured.

ON a stateful inspection Firewall where there is no session table, when the status detection mechanism is enabled and the second packet (CYN+ACK) of 3-way hadshakes reaches the firewall. Which of the following statements is true?

If the firewall security policy permits packets to pass, the packets can pass the firewall.

If the firewall security policy permits packets to pass, the session table is created.

By default, when status detection is disabled and the permit policy is configured packets can pass.

Packets must pass the firewall, and a session table is established.

If the firewall security policy permits packets to pass, the packets can pass the firewall.
