Printing

Which of the following is a computer system or an application/service that acts as an intermediary between a network host and the Internet?

Proxy

Which of the following wireless technologies enables identification and tracking of tags attached to objects?

RFID

Automatic Private IP Addressing (APIPA) allows a Windows host to self-configure an IP address and subnet mask when a Dynamic Host Configuration Protocol (DHCP) is unavailable. APIPA uses an address block range between 169.254.0.0 and 169.254.255.255. APIPA-assigned addresses are valid only for communications within the network segment that a given host is connected to (i.e. a host with an APIPA-assigned address cannot connect to the Internet).

True

Dynamic Host Configuration Protocol (DHCP) allows for static allocation of an IP address based on an IP-to-MAC address mapping.

True

Intrusion Detection Systems (IDSs) are devices or software applications designed to detect malicious activities or violations of security policies on a network or computer host. An IDS designed to monitor networks is known as a Network Intrusion Detection System (NIDS); an IDS monitoring a single host is called a Host Intrusion Detection System (HIDS). An IDS does not take any active steps to prevent or stop intrusions, relying on passive responses such as sending an alert to a management console or recording information about an event in logs.

True

Long Term Evolution (LTE) is a wireless communications standard for mobile devices and wireless hotspots. LTE is much faster than the older generation of 2G and 3G cellular networks. Both LTE and its later upgrade, LTE-Advanced (LTE-A), are often marketed as 4G standards.

True

Multiple Input / Multiple Output (MIMO) is a wireless technology that allows for significant increase in data throughput due to the use of multiple antennas and multiple data streams.

True

Network Address Translation (NAT) provides an IP proxy between a private LAN and a public network such as the Internet.

True

Networked clients not residing on the same subnet as a DHCP server can still obtain an IP address from the server through a DHCP relay agent (a.k.a. IP helper).
