What is called an attack where the attacker spoofs the source IP address in an ICMP ECHO broadcast packet so it seems to have originated at the victim's system, in order to flood it with REPLY packets?

• SYN Flood attack
• Smurf attack
• Ping of Death attack

• A Smurf attack is ICMP-based and a Fraggle attack is UDP-based.

Why are coaxial cables called "coaxial"?

• it includes two physical channels that carries the signal

surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis.

• it includes one physical channel that carries the signal

surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis

• it includes two physical channels that carries the signal

surrounded (after a layer of insulation) by another two concentric physical channels, both running along the same axis.

• it includes one physical channel that carries the signal

surrounded (after a layer of insulation) by another concentric physical channel, both running perpendicular and along the different axis

• it includes one physical channel that carries the signal surrounded (after a layer

of insulation) by another concentric physical channel, both running along the same axis The International Standards Organization / Open Systems Interconnection (ISO/OSI) Layers does NOT have which of the following characteristics?

• Standard model for network communications
• Used to gain information from network devices such as

count of packets received and routing tables

• Enables dissimilar networks to communicate
• Defines 7 protocol layers (a.k.a. protocol stack)
• Used to gain information from network devices such as count of packets

received and routing tables In telephony different types of connections are being used. The connection from the phone company's branch office to local customers is referred to as which of the following choices?

One of the following statements about the differences between PPTP and L2TP is NOT true

• PPTP can run only on top of IP networks.
• PPTP is an encryption protocol and L2TP is not.
• L2TP works well with all firewalls and network devices

You have been tasked to develop an effective information classification program. Which one of the following steps should be performed first?

• Establish procedures for periodically reviewing the

classification and ownership

• Specify the security controls required for each

classification level

• Identify the data custodian who will be responsible for

maintaining the security level of data

A group of independent servers, which are managed as a single system, that provides higher availability, easier

manageability, and greater scalability is:

• server cluster
• client cluster
• guest cluster
• host cluster
• server cluster

A server cluster looks like a:

• single server from the user's point of view
• dual server from the user's point of view
• triple server from the user's point of view
• quardle server from the user's point of view
• single server from the user's point of view

If any server in the cluster crashes, processing continues transparently, however, the cluster suffers some performance degradation. This implementation is

sometimes called a:

• server farm
• client farm
• cluster farm
• host farm
• server farm

Which of the following is immune to the effects of electromagnetic interference (EMI) and therefore has a much longer effective usable length?

• Fiber Optic cable
• Coaxial cable
• Twisted Pair cable
• Axial cable
• fiber optic cable

Which of the following methods of providing telecommunications continuity involves the use of an alternative media?

• Alternative routing
• Diverse routing
• Long haul network diversity
• Last mile circuit protection
• alternative routing
