A. queue "C1" will get 4M, "D2" 3M, "D1" 3M B. queue "C1" will get 3M, "D2" 3M, "D1" 5M C. queue "C1" will get 5M, "D2" 2M, "D1" 3M D. queue "C1" will get 4M, "D2" 7M, "D1" 4M E. queue "C1" will get 2M, "D2" 5M, "D1" 3M 13. You want to offer a static route to your DH clients (besides the default-route). What is the best way to do that? A. Set DH options 3 B.

DH server is configured on a router’s ether1 interface. IP address 192.168.0.100/24 is assigned to the interface. Possible IP pools, that can be used by this DH server, are:

A. PCQ B. RED C. PFIFO D. FIFO E. SFQ 21. You have a queue structure: queue "GP" max-limit=10M - queue "M" parent="GP" limit-at=4M max-limit=6M - - queue "C1" parent="M" limit-at=1M max-limit=7M priority=4 - - queue "C2" parent="M" limit-at=1M max-limit=4M priority=1 - - queue "C3" parent="M" limit-at=2M max-limit=7M priority=8 - queue "F" parent="GP" limit-at=5M max-limit=8M - - queue "D1" parent="F" limit-at=3M max-limit=4M priority=5 - - queue "D2" parent="F" limit-at=2M max-limit=5M priority=2 Which queue will get more than limit-at in worst case scenario?

A. C1 B. D1

C. C3 D. C2 E. D2 22. Select types of Load Balancing methods A. PCC B. PCQ C. NTH D. ECMP 23. log messages are stored on disk by default

24. Same IP address can be included in multiple address-lists, and these lists can be used separate from one another.

25. An IP packet has matched all the conditions of a firewall rule and the action reject and the option icmp-network-unreachable was initiated for that packet. What will happen with the packet content ? A. The packet header will receive a flag of \\\"icmpnetwork-unreacheble\\\" B.
