- Router(config)# dialer-list 1 protocol ip permit
- Router(config)# dialer map ip 192.168.100.1 name sanjose 555 1234
- Router(config-if)# dialer-group 1
- Router(config-if)# dialer 1 string 555-5000

Which networking devices can be used at the access layer of the hierarchical network design model? (Choose two.)
- AUI
- hub
- Layer 3 switch
- ISDN hub
- Layer 2 switch
- Frame Relay switch

Which of the following are the address ranges of the private IP addresses? (Choose three.)
- 10.0.0.0 to 10.255.255.255
- 200.100.50.0 to 200.100.25.255
- 150.150.0.0 to 150.150.255.255
- 172.16.0.0 to 172.31.255.255
- 192.168.0.0 to 192.168.255.255
- 127.16.0.0 to 127.31.255.255

A company is using an address range of 172.18.0.0/23. Which of the following are valid host addresses if the zero subnet is usable? (Choose three.)
- 172.18.0.0
- 172.18.0.174
- 172.18.1.0
- 172.18.1.236
- 172.18.1.255
- 172.18.2.182

A company has 200 hosts that are assigned addresses from the 172.68.1.0/24 network. A planned expansion will result in an additional 400 hosts. What is the most technically effective and most cost effective way to provide the necessary host addresses for this expansion?
- Arrange for a Class B registered address.
- Share IP addresses between multiple hosts.
- Use private IP addresses with PAT.
- Use VLSM to more efficiently utilize the existing addresses.
- Arrange for additional Class C registered addresses.
- Restrict access using extended ACLs.

Which of the following are features of a link-state routing protocol? (Choose two.)
- Routers send periodic updates only to neighboring routers.
- Routers send triggered updates in response to a change.
- Routers calculate best paths based on the Dijkstra algorithm.
- The database information for each router is obtained from the same source.
- Paths are chosen based on the lowest number of hops to the designated router.

What is the purpose of the passive-interface command?
- allows a routing protocol to forward updates out an interface that is missing its IP address
- allows a router to send routing updates on an interface but not receive updates via that innterface
- allows an interface to remain up without receiving keepalives
- allows interfaces to share IP addresses
- allows a router to receive routing updates on an interface but not send updates via that interface

Which three aspects of an ISDN connection can be defined when using dialer profiles to different locations? (Choose three.)
- physical interface
- IP addressing
- routing protocol
- error correction
- encapsulation
- bandwidth

Refer to the graphic. A named access list called chemistry_block has been written to prevent users on the chemistry network and public Internet from access to the records server. All other users within the school should have access to this server. The list contains the following statements:
deny 172.16.102.0 0.0.0.255 172.16.104.252 0.0.0.0
permit 172.16.0.0 0.0.255.255 172.16.104.252 0.0.0.0
Which of the following command sequences will place this list to meet these requirements?

- Hera(config)# interface e0
Hera(config-if)# ip access-group chemistry_block in
- Hera(config)# interface s0
Hera(config-if)# ip access-group chemistry_block out
- Apollo(config)# interface s0
Apollo(config-if)# ip access-group chemistry_block out
- Apollo(config)# interface s1
Apollo(config-if)# ip access-group chemistry_block in
- Athena(config)# interface s1
Athena(config-if)# ip access-group chemistry_block in
- Athena(config)# interface e0
Athena(config-if)# ip access-group chemistry_block out

With VLSM, which bit mask should be used to most efficiently provide for the number of host addresses required on Router B?
[img]04modul12_55.jpg[/img]
- /26
- /27
- /28
- /29
- /30

Which of the following router connections is most often to be used to connect a LAN?
- BRI
- synchronous/asynchronous serial
- console
- Fast Ethernet
