- Question
What is the purpose of flow control?
Options- A. To ensure that data is retransmitted if an acknowledgment is not received
- B. To reassemble segments in the correct order at the destination device
- C. To provide a means for the receiver to govern the amount of data sent by the sender
- D. To regulate the size of each segment
- Correct Answer
- To provide a means for the receiver to govern the amount of data sent by the sender
ExplanationFlow control allows the receiving device to control the transmitter so the receiving device's buffer does not overflow.

Correct Answer: RIP version 1 and IGRP are classful protocols and do not advertise subnet mask information RIP version 2 has a limited network diameter of 15 hops EIGRP, OSPF, and IS-IS use computational intensive algorithms for determining a shortest path BGP relies on simple techniques for best path selection and loop detection, and can handle the number of network prefixes required for Internet routing
Correct Answer: Transitive trust
Explanation:
By default, all Windows 2000 trusts within a domain tree or forest are transitive trusts.
Correct Answer: IPSec
Explanation:
IPSec is an industry-wide standard suite of protocols and algorithms that allows for secure data transmission over an IP-based network that functions at the layer3 Network layer of the OSI model.
Correct Answer: : E
Correct Answer: Host-to-Host
Explanation:
The four layers of the TCP/IP stack (also called the DoD model) are Application/process, Host-to-Host, Internet, and Network Access. The Host-to-Host layer is equivalent to the Transport layer of the OSI model.
Correct Answer: Answer
Correct Answer: : C Explanation: FrameRelay, ATM, and X25 are non-broadcast multiple access (NBMA) networks NBMA networks allow only data transfer from one computer to another over a VC or across a switching device NBMA networks do not support multicast or broadcast traffic FrameRelay, ATM, and X25 are non-broadcast multiple access (NBMA) networks NBMA networks allow only data transfer from one computer to another over a VC or across a switching device NBMA networks do not support multicast or broadcast traffic - See more at: https://wwworbitco-ccna-pastquestionscom/CCNA-Past-Questions%3A-WANphp#sthashhb05ZKYsdpuf
Correct Answer: : A , D Explanation: An IPv6 Unicast address identifies a single network interface The Internet Protocol delivers packets sent to a unicast address to that specific interface
Correct Answer: DHCP
Explanation:
Dynamic Host Configuration Protocol (DHCP) is used to provide IP information to hosts on your network. DHCP can provide a lot of information, but the most common is Ip address, subnet mask, default gateway, and DNS information.
Correct Answer: It is used to bypass the configuration in NVRAM
Explanation:
The default configuration setting is 0x2102, which tells the router to load the IOS from flash and the configuration from NVRAM. 0x2142 tells the router to bypass the configuration in NVRAM so that you can perform password recovery.
