Demo Questions
Question 1
You are configuring your Nokia 7750SR Service Router from the Command Line Interface (CLI), and after entering a lengthy command, wish to return directly to the ROOT context. Which control command allows you to do this quickly?
- Ctrl-z
- Ctrl-c
- Esc
- Shift-Page Down
Correct answer: A
Question 2
How do protocols such as ATM and Frame-Relay support differentiating multiple customers or traffic types on the same physical wire?
- ATM and Frame-Relay are circuit switched protocols and use Virtual Circuits to create logical separation of traffic.
- ATM and Frame-Relay are point-to-point protocols and do not support different customers or traffic type on the same physical wire.
- ATM and Frame-Relay are circuit switched protocols and use VLAN's to create logical separation of traffic.
- ATM and Frame-Relay are circuit switched protocols and use IP Header information to create logical separation of traffic.
Correct answer: A
Question 3
Which of the following is the best description of well known ports?
- Well known ports apply to routers only and are used for communication and control traffic. Well known port numbers are assigned by IANA and can have any value.
- Well known ports are used by TCP and UDP. Well known port numbers range from 1024 to 65535 and are assigned by IANA.
- Well known port numbers are used by both TCP and UDP. Well known port numbers range from 1 to 1023 and are assigned by IANA.
- Well known ports numbers are used by TCP only. Well known port numbers are assigned by IANA and can have any value.
Correct answer: C
Question 4
Which organization first considered cross-platform networking support to be a necessity?
- IBM.
- US Military.
- Nokia.
- NASA.
- Bell Labs
Correct answer: B
Question 5
Which of the following statements best describes ARPANET?
- ARPANET was an early packet switched network initially connecting 4 sites (Stanford, UC Santa Barbara, UCLA, and U of Utah).
- The mission of ARPANET was to connect packet switched networks and other diverse networks, making an international network of networks.
- ARPANET connected sites spread around the Hawaiian Islands to a central time-sharing computer on the University of Hawaii campus.
- ARPANET was based on the use of TCP/IP to interconnect diverse systems.
Correct answer: A
Question 6
Kahn solved the problem of interconnecting different networks using different protocols by pioneering a new protocol called TCP that was capable of:
- Secure transmission of information.
- Enforcing a constant packet size to avoid discards.
- Allowing remote logins.
- Providing host to host connectivity with global addressing.
Correct answer: D
Question 7
Which network was created to replace ARPANET?
- INWG
- ALOHANET
- IETF
- NSFNET
Correct answer: D
Question 8
What is the name for an organization that provides Internet services to its customers?
- A large corporation.
- An ISP.
- A home based business.
- A content provider.
Correct answer: B
Question 9
The IANA is responsible for:
- Intra-city ISP traffic
- Allocation of the global IP address space
- Allocating IP addresses for residential customer traffic
- Allocating North American IP addresses
Correct answer: B
Question 10
Which of the following is an important advantage of protocol layering? (Choose two)
- Controls distribution of IP addresses.
- Simplifies protocol functionality.
- Isolates changes in lower layers from upper layers.
- Increases protocol operational efficiencies.
- Layering adds to the fragmentation of the data
Correct answer: CD
