What is the primary goal of HA (high availability)?

• Ensuring operational uptime higher than normal

• Carrying out attacks on a computer software program

• Transmitting data in both directions simultaneously

• Monitoring and analyzing data coming to and from the host

Answer explanation

The primary goal of HA (high availability) is to ensure operational uptime higher than normal, making sure systems are consistently accessible and reliable.

What does a hacker do?

• Ensures operational uptime higher than normal

• Carries out attacks on a computer software program

• Transmits data in both directions simultaneously

• Monitors and analyzes data coming to and from the host

Answer explanation

A hacker carries out attacks on a computer software program, aiming to exploit vulnerabilities and gain unauthorized access.

What is the difference between half duplex and full duplex?

• Half duplex transmits data in both directions simultaneously, while full duplex does not

• Half duplex transmits data in both directions but not simultaneously, while full duplex does

• Half duplex ensures operational uptime higher than normal, while full duplex does not

• Half duplex monitors and analyzes data coming to and from the host, while full duplex does not

Answer explanation

Half duplex transmits data in both directions but not simultaneously, while full duplex does

What is a handshake in data communication?

• The initial communication between two data communication devices to agree on protocol and transfer rules

• A system goal aimed at ensuring operational uptime higher than normal

• A device plugged into an interface for the purposes of simulating a network connection

• An identifier used to uniquely identify a client or resource on a network

Answer explanation

The initial communication between two data communication devices to agree on protocol and transfer rules

What is a hardware address?

• The hardware-encoded MAC address burned into every NIC

• A device plugged into an interface for the purposes of simulating a network connection

• An ISO developed bit-oriented synchronous data link layer protocol

• An audio/video interface for transferring data and compressed or uncompressed data to a monitor

Answer explanation

The hardware address is the hardware-encoded MAC address burned into every NIC, making it the correct choice.

What is the purpose of a hardware loopback?

• To simulate a network connection and test the interface as if it is operating while connected

• To ensure operational uptime higher than normal

• To carry out attacks on a computer software program

• To transmit data in both directions but not simultaneously

Answer explanation

To simulate a network connection and test the interface as if it is operating while connected

What is HDLC (High-Level Data Link Control)?

• An ISO developed bit-oriented synchronous data link layer protocol used for point-to-point or point-to-multipoint connections

• An audio/video interface for transferring data and compressed or uncompressed data to a monitor

• A system goal aimed at ensuring operational uptime higher than normal

• A device plugged into an interface for the purposes of simulating a network connection

Answer explanation

An ISO developed bit-oriented synchronous data link layer protocol used for point-to-point or point-to-multipoint connections

What is HDMI (High-Definition Multimedia Interface) used for?

• Transferring data and compressed or uncompressed data to a monitor, projector, television, or digital audio device

• Ensuring operational uptime higher than normal

• Carrying out attacks on a computer software program

• Transmitting data in both directions but not simultaneously

Answer explanation

HDMI is used for transferring data and compressed or uncompressed data to a monitor, projector, television, or digital audio device.

What does HIDS (host intrusion detection system) do?

• Monitors and analyzes data coming to and from the host

• Ensures operational uptime higher than normal

• Transmits data in both directions but not simultaneously

• Carries out attacks on a computer software program

Answer explanation

HIDS (host intrusion detection system) monitors and analyzes data coming to and from the host, making it the correct choice.

What is HIPS (host intrusion prevention system)?

• An intrusion prevention system that is based at the host and responds to threats coming to and from the host

• A system goal aimed at ensuring operational uptime higher than normal

• A device plugged into an interface for the purposes of simulating a network connection

• An audio/video interface for transferring data and compressed or uncompressed data to a monitor

Answer explanation

An intrusion prevention system that is based at the host and responds to threats coming to and from the host
