A command at the rommon prompt that bypasses the stored startup configuration in NVRAM is - A)config-register 0x2142 B)config-register 0x2102 C)conf t 0x2142 D)password-bypass local-startup
What is config-register 0x2142 This is the correct answer and will put the device into rommon mode where you can boot the router, edit the startup configuration to reset the password and regain access to the device.

Stateless Autoconfiguration is a feature of this, eliminating the need for DHCP.
What is IPV6

This type of domain is separated by network switches.
What is a collision domain

The destination field on an Ethernet frame header contains this.
What is the destination MAC address

These two protocols collect information about the locally-attached devices on a network.
What are CDP and LLDP Discussion: CDP - Cisco Discovery Protocol and LLDP - Link Layer Discovery Protocol defined by the IEEE are two protocols for discovering technical information about adjacent devices from simple advertisements sent by the devices. They help administrators troubleshoot networks and understand the layout of their networks. CDP and LLDP information is broadcasted out interfaces and adjacent devices process the data. It is accessible by the device administrator through simple show commands. You can disable these protocols to give attackers a bit more trouble in doing a recon of your network.

This type of wire mitigates the problem of EMI
What is UTP. UTP - Unshielded Twisted Pair is the single most popular cabling type in the networking world and speeds have improved over the years specifically because engineers realized that when you twist wires together, it can help disrupt EMI because of how radio signals travel. Wire twisting permits us to achieve greater than gigabit ethernet data transfers because the crosstalk is mitigated permitting higher data rates. When interference is higher, frames can be corrupted by the crosstalk from EMI and they must be retransmitted which slows down data rates.

In ICMPv6, this replaced ARP. a) NDP b)UDP c)Stateless Autoconfiguration d)Dynamic DNS
What is ARP was replaced with NDP - Neighbor Discovery Protocol which enabled these functions: - SLAAC - Stateless Address Auto Configuration - Determine MAC address of neighbors - Router solicitation - Router advertisements - Neighbor solicitation - Neighbor advertisement - Duplicate address detection

This type of domain is separated by Routers
What is a Broadcast domain.

A switch does this when it receives a frame with a MAC address for which it has no entry in the Switch CAM table?

Letters and letters, can be sent with this protocol,
What is SMTP

This type of straight wire is used to connect a host and a switch together.
What is a Straight-Through cable. It is important to understand that with Ethernet networks and devices, there are four pair or eight wires in a cable. only 1, 2, 3 and 6 are used for transmit and receive (Respectively) and that there are different types of cables we use to connect the different devices which we we use. To connect switches together, you need a crossover cable because each switch's send and receive pairs are the same and the crossover cable crosses those so that the transmit circuit is talking to the receive circuit on the other device. When connecting a computer to a switch, you'd need a straight-through cable so that the transmit wires are talking to the receive wires on the other device.

This, the the name for a Unicast IPv6 address that isn't used for normal packet flows with data but used only on the local subnet.
What are the link local addresses.
300
These types of switchport modes can connect two switches together.
What are dynamic desirable and trunking Discussion: When we plug a computer into a switch port, the switch port mode must be in Access or Dynamic Desirable for the computer or switch to be able to communicate. When we're connecting two switches together, the switch ports on each must be in a mode that permits trunking to happen either with switchport mode trunking or dynamic desirable. The default mode for a Cisco switch is dynamic desirable, which is best because it will save you from trying to troubleshoot a problem later. Keep this in mind when troubleshooting a Cisco internetwork.

This is the maximum size for data and padding in an 802.3 ethernet frame.
What is 1500 Bytes

Avoid the storm with this protocol
What is STP. - STP: Spanning Tree Protocol is used to create a seamless, single-path switch pathway through the layer two network and avoid switching loops. If STP wasn't used, layer two frames would circulate endlessly around the network causing broadcast storms and clogging bandwidth.

This method of identifying a range of addresses, might be considered upside down to some.

All ports on a switch are by default part of this.
What is VLAN 1

This WAN method allows us to share bandwidth with other companies and use Frame Relay on the connection?
What is Packet Switching Discussion: Packet Switching is a more common WAN Connection type where we connect to "The Internet" and our data is packet switched to and from systems. Speed ranges from 56Kbps to 45Mbps and faster. If you have an internet connection in your enterprise network, you probably use a Packet Switched network with TCP/IP on MPLS or Frame Relay.
400
This protocol is commonly used to move files between routers and servers.
What is TFTP When we must move files around between routers, switches and servers, it is very common for people to use TFTP - Trivial File Transfer Protocol to do so. It is a lightweight file transfer protocol that doesn't use authentication and runs on UDP/69 for a transport protocol

This is the fastest of the three packet forwarding techniques used by cisco.
What is Cisco express forwarding, Cisco uses three types of packet-forwarding techniques. Process Switching, Fast Switching and Cisco Express Forwarding or CEF.

This is a tunneling protocol that can encapsulate many protocols like EIGRP, OSPF or IPv4/IPv6? a) GRE b)PPP c)HLDC d)Frame Relay
What is GRE or Generic routing encapsulation GRE or Generic Routing Encapsulation is a tunneling protocol developed by Cisco that encapsulates many protocols into GRE headers for routing across networks. It supports encapsulation of IPv4, IPv6, EIGRP and OSPF or other similar protocols.
