Helping Hand Questions for H12-222

After a static LSP is established, each node on the LSP can detect the entire LSP.

When MPLS is enabled on the outbound interface of the ingress node and the physical status and the protocol status of the outbound interface are Up, the static LSP is Up regardless of whether there is an egress node or a transit node.

The transit node of a static LSP is configured and MPLS is enabled on both the inbound and outbound interfaces. If the physical status and the protocol status of the inbound and outbound interfaces are Up, the static LSP is Up.

The egress node of the static LSP is configured and MPLS is enabled on the inbound interface. If the physical status and the protocol status of the inbound interface are Up, the static LSP is Up regardless of whether there is an ingress node or a transit node.

The first 6 bits of the ToS field (leftmost 6 bits) mark different types of services, namely, DSCP priority.

The DSCP priority can be used to classify traffic into 32 types.

Each DSCP priority corresponds to a Behavior Aggregate (BA), and a PHB can be specified for each BA.

You can use some QoS mechanisms to implement PHB.

As the ACL complexity and length increase, the firewall filtering performance deteriorates exponentially.

Static ACL rules cannot adapt to dynamic security filtering requirements.

It is easy for hackers muddle through without check the session state and analyze the data.

It can fully control network information exchange, and Session control is of high security.
