Question 721

Which of the following statements regarding the static LACP mode are false?

If a high bandwidth of the link between two directly connected devices is required bot the remote device does not support LACP, you can use the manual load balancing mode.

In static LACP mode, a larger LACP priority of an interface indicates a higher priority of the interface and a high probability of becoming the active interface.

The interface that forwards data is called the active interface, whereas the interfaces that does not forward data is called the inactive interface. The backup interface changes from inactive to active only when the active interface dails.

When preemption is enabled and an active interface fails, the backup interface with a larger priority becomes the active interface after a delay. If preemption is disabled, the faulty interface cannot automatically become the active interface.

Question 722

Which of the following statements regarding MUX VLAN is false?

Each group VLAN must be bound to a principal VLAN.

If the VLAN ID has been used by the principal VLAN, this VLAN cannot be used for the VLANIF interface, super-VLAN, or sub-VLAN.

After MUX VLAN is enabled on an interface, VLAN mapping and VLAN stacking can be configured on the interface.

An enterprise can use the principal port to connect to the enterprise server, a separate port to connect to enterprise customers, and a group port to connect to enterprise employees. Enterprise customers and employees can both accessenterprise servers, enterprise employees can communicate with each other, enterprise customers cannot communicate with each other, and enterprise customers and employees cannot communicate with each other.

Question 723

Port isolation provides secure and flexible networking solutions for users. Which of the following statements regarding port isolation is false?

Port isolation can be used for configuring Layer 2 isolation.

By default, interfaces are isolated at Layer 2 but can communicate at Layer 3.

Before the port isolation function takes effect on an interface, the port isolation function must be enabled.

The port-isolate enable command can run in the system view.

Question 725

RSTP provides faster convergence than STP. What are causes? (Choose all that apply.)

RSTP defines the edge port role. The edge port does not receive and process configuration BPDUs, and not participate in RSTP calculation. The edge port can directly change from the Disable state to the Forwarding state.

When the root port fails, the optimal alternate port will become the root port and enter the Forwarding state.

In RSTP, when a port is elected as the designated port, it enters the Discarding state. Then the port immediately enters the Forwarding state through theProposal/Agreement mechanism.

In RSTP, when a port receives RST BPDUs from the upstream designated bridge, the port will compare the own stored RST BPDU will the received RSTBPDU.

When the designated port fails, the optimal alternate port will become the root port and enter the Forwarding state.

Question 727

Which of the following LSPs are established in Downstream Unsolicited (DU) label advertisement mode and ordered label distribution control mode? (Choose three.)

When the edge node finds a new destination address in its routing table that does not belong to any existing FEC, the edge node does not create a new FEC for the destination address.

An LSP is established by binding an FEC to a label and advertising the binding relationship to the neighboring LSR.

If the egress node has available labels for distribution, it allocates labels for the FEC and sends a label mapping message to the upstream node.

After receiving a label mapping message, the LSR adds the corresponding entry to the label forwarding table.

Question 730

In a MPLS VPN network, two-layer MPLS labels are added to data packets before they are transmitted over the public network. Which of the following statements regarding two-layer labels are false? (Choose two.)

The outer label is the private network label and the inner label is the public network label.

The MPLS VPN outer label is distributed manually by the LDP protocol. The inner label is distributed by the peer MP-BGP neighbor.

By default, the outer label in data packets is popped out before being forwarded to the last hop.

The outer label is used to instruct the PE to send data packets to the correct VPN.
