An IPv6 address is 128 bits long.

All exception in Java are subclasses of built in class called Throwable.

Port Address Translation (PAT) allows a one-to-many approach to network address translation.

In 32 bit IP Addressing scheme all 1’s represent limited broadcast

Standard and extended access control lists (ACLs) are used to configure security on a router.

DMSP stands for – Distributed Mail system Protocol.

The command to back up the configuration on a router is copy running-config startup-config.

Presentation layer is not present in TCP/IP Model

Each device has 10 Mbps to the server.

IEEE 802.11B is 2.4GHz, but with a maximum of only 11Mbps. IEEE 802.11G is in the 2.4GHz range, with a top speed of 54Mbps.

Address 192.5.48.3 belongs to class C.

256 - 192 = 64. 64 + 64 = 128. 128 + 64 = 192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129-190.

Unlike Ipv4, Ipv6 does not include the Field for Fragmentation information
in the base header.

The command copy flash tftp will prompt you to back up an existing IOS in flash to a TFTP host.

The term byte stuffing refers to data stuffing used with character-oriented
hardware.

Network Control Protocol is used to help identify the Network layer protocol used in the packet.

FDDI is an example of token ring

The command line vty 0 4 places you in a prompt that will allow you to set or change your Telnet password.

Hardware that calculates CRC uses shift register and Xor unit.

User Datagram Protocol is a connection network service at the Transport layer, and DHCP uses this connectionless service.

In TCP protocol header checksum is of 16 bits.

The show ip interface command will show you if any outbound or inbound interfaces have an access list set.

In IP addressing scheme, class used for multicasting is class D.

Hubs regenerate electrical signals, which are specified at the Physical layer.

CIDR stands for Classless Inter Domain Routing

The passive command, short for passive-interface, stops regular updates from being sent out an interface. However, the interface can still receive updates.

The total number of class of IP addresses are 5.

ICMP is the protocol at the Network layer that is used to send messages back to an originating router.

Parent class of all Java classes is java.lang.object.

Every 2 seconds, BPDUs are sent out from all active bridge ports by default.

Exceptions of type error in JAVA are handled by JAVA run time
environment.

By default, switches break up collision domains but are one large broadcast domain.

Error detecting method that can detect more errors without increasing  additional information in each packet is CRC.

The command line console 0 places you at a prompt where you can then set your console user-mode password.
