- Question
What does the command confreg 0x2142 provide?
Options- A. It is used to restart the router
- B. It is used to bypass the configuration in NVRAM
- C. It is used to enter ROM monitor mode
- D. It is used to view the lost password
- Correct Answer
- It is used to bypass the configuration in NVRAM
ExplanationThe 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.

- 2. Which two descriptions are correct about characteristics of IPv6 unicast addressing? (Choose two) A. Global addresses start with 2000::/3. B. Link-local addresses start with FF00::/10. C. Link-local addresses start with FE00:/12. D. There is only one loopback address and it is ::1. Discuss
- 3. A default Frame Relay WAN is classified as what type of physicalnetwork? A: broadcast point-to-multi point B: broadcast multi-access C: non broadcast multi-access D: non broadcast multi-point Discuss

- 5. 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 Discuss

Options- A. disable spanning-tree
- B. spanning-tree off
- C. spanning-tree security
- D. spanning-tree portfast Discuss
- 7. Which of the following describes the creation of private networks across the Internet, enabling privacy and tunneling of non-TCP/IP protocols?
Options- A. HDLC
- B. Cable

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: : 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: : 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: Answer
Correct Answer: To provide a means for the receiver to govern the amount of data sent by the sender
Explanation:
Flow control allows the receiving device to control the transmitter so the receiving device's buffer does not overflow.
Correct Answer: spanning-tree portfast
Explanation:
If you have a server or other devices connected into your switch that you're totally sure won't create a switching loop if STP is disabled, you can use something called portfast on these ports. Using it means the port won't spend the usual 50 seconds to come up while STP is converging.
Correct Answer: VPN
Explanation:
A VPN allows or describes the creation of private networks across the Internet, enabling privacy and tunneling of non-TCP/IP protocols. A VPN can be set up across any type of link.
Correct Answer: Unicast IP packets are forwarded based on the destination IP address Multicast packets are forward based on the source IP address If a multicast packet is received on the interface used to send a unicast packet back to the source, the multicast packet is forwarded to multicast neighbors If the multicast packet is received on an interface that would not be used to send a unicast IP packet back to the source, the packet is discarded
Correct Answer: Areas allow the design of a hierarchical network Routes can be summarized or blocked in an area to reduce the amount of routing information on internal OSPF routers
Correct Answer: Intra-area, inter area, El, E2, Nl, and N2
