A. To implement load balancing, default network gateways of hosts on a LAN must be configured as IP addresses of different virtual routers.

B. When configuring priorities, you must ensure that the same router serves as the master router in three VRRP backup groups.

C. VRRP local balancing requires that at least two virtual routers transmit services at the same time.

D. Multiple VRRP backup groups can be created on an interface of a router. The router can serve as the master router in one VRRP backup group and the backup router in other VRRP backup groups.

A. If the retransmission timer expires without the sender receiving an ACK message, the receiver retransmits the packet to the sender.

B. The initial window offer is advertised by the sender.

C. The size of the sliding window can only increase or stay the same.

D. The sender need not transmit a full window's worth of data.

E. The receiver is required to acknowledge the data packets transmitted by the sender.

F. It allows the transmission of multiple frames before waiting for an acknowledgement.

A. IS-IS GR defines a new TLV architecture to support this feature.

B. IS-IS GR is enabled by default.

C. IS-IS GR notifies events and maintains the neighbor relationship through CSNP packets.

D. IBS-IS GR has four timers.

A. Traffic with low bandwidth is more likely to be discarded than traffic with high bandwidth.

B. When traffic exceeds the minimum threshold, WRED starts to discard all inbound traffic (tail drop).

C. WRED selectively discards multiple TCP flows to avoid global synchronization.

D. WRED can be used to set different drop thresholds and packet loss ratio for data packets with different priorities.
