Options- A. HDLC
- B. Cable
- C. VPN
- D. IPSec
- Correct Answer
- VPN
ExplanationA 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: 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: 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.
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: 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
Correct Answer: Both A and B
Correct Answer: Examines packets and decides which ones should be allowed to pass from one network to another.
