Which of the following statements regarding multicast are false? (Multiple Choice)

• A.Unicast and broadcast technologies cannot implement point-to-multipoint transmission. Only multicast technology can implement this function.
• B.Multicast technology can reduces redundant traffic and conserves bandwidth on a network.
• C.Multicast technology is applicable to most of point-to-multipoint data transmission applications.
• D.Multicast technology is based on TCP, so it can ensure reliable transmission of packets.

BGP is an enhanced distance-vector muting protocol.
Which is the major reason for this?

• A.BGP does not accept the mutes whose AS_Path attribute contains the local AS number.
• B.Nexthop is a well-known mandatory attribute of BGP mutes.
• C.The AS_Path attribute records all the ASs that a BGP route passes through on the transmission path. In route selection rules, a route with a shorter AS_Path is preferred, and the AS_Path attribute is also checked in IBGP.
• D.The AS_Path attribute records all the ASs that a BGP route passes through on the transmission path. In route selection rules, a route with a shorter AS_Path is preferred.

RSTP provides faster convergence than STP.
What are causes? (Multiple Choice)

• A.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.
• B.When the root port fails, the optimal alternate port will become the root port and enter the Forwarding state.
• C.When the designated port fails, the optimal alternate port will become the root port and enter the Forwarding state.
• D.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 the Proposal/Agreement mechanism.
• E.In RSTP, when a port receives RST BPDUs from the upstream designated bridge, the port will compare the own stored RST BPDU with the received RST BPDU.

What is the default priority of the device in a VRRP group?

• A.100
• B.0
• C.150
• D.200

which of the following statements regarding the route injected into BGP using the network command are false?

• A.this route must exist in the IP routing table and be the optimal route.
• B.this route must match the specified prefix and does not need to accurately match the mask length.
• C.this route must accurately match the specified mask length.
• D.this route must be on IGP route.
