In standard GRUB notation, select the option below that represents the first hard drive in a system, and the first partition on that hard drive.

2

What is the role of a hypervisor in terms of allocating hardware?

3

Discuss how an ESS works.

For an Extended Service Set (ESS), BSS networks are connected through a common distribution system, and APs are strategically placed so that users can move through a wider BSA. Although APs are often configured with different channels to prevent co-channel interference, the range of channels (the WLAN's frequency range) is part of the ESS. Like a BSS, the entire ESS network has a unique SSID.
In an ESS, APs are set up to provide some overlap. The coverage areas are called cells, and the WLAN is set up like a cell phone system. Movement between AP coverage areas is called roaming. When mobile users move into a new coverage area, their devices select the AP with the best signal strength. After the AP accepts the roaming device, the device tunes to the AP's channel but continues to survey radio frequencies at regular intervals to see whether another AP can provide a stronger signal.

19

Expand the acronym MAC.

20

21

22

A digital certificate usually contains all of the following EXCEPT ____.

23

Which key part of the NY DFS Cybersecurity Regulation covers training and monitoring?

24

What are the risks of the typical recovery options?

25

IrDA links are direct ______________ and are susceptible to interference.

26

Under which law must healthcare enterprises guard protected health information and implement policies and procedures to safeguard it, whether it be in paper or electronic format?

27

You are a network administrator, and you are bringing up a new FTP server in the company's domain. What must you ensure happens as far as DNS is concerned?

28

What are applied to the packets that are captured into the trace buffer so you can see the packets in a readable format?

29

Over _________ percent of all TCP/IP applications use TCP as their transport protocol.

30

A collection of devices connected via Bluetooth technology is called a(n) ____.

31

The SOW does not include the criteria that will be used to determine whether the change was successful.

32

Key ____ indicators provide a description of the outcome of each control activity, and each key goal must be measurable.

33

A security advantage of VLANs is that they can be used to prevent direct communication between servers.

34

Which of the following is true about free space optics?

35

The ____ layer in the TCP/IP model is a direct equivalent to the Network layer in the OSI reference model.

36

What are some of the PSK key management weaknesses?

PSK key management weaknesses include the following:
* Like WEP, the distribution and sharing of PSK keys is performed manually without any technology security protections. The keys can be distributed by telephone, e-mail, or a text message (none of which are secure). Any user who obtains the key is assumed to be authentic and approved.
* Unlike WEP, in which four keys can be used, PSK only uses a single key. Should this one PSK key be compromised by an unauthorized attacker the entire WLAN would become vulnerable.
* Standard security practices call for keys to be changed on a regular basis. Changing the PSK key requires reconfiguring the key on every wireless device and on all access points.
* To allow a guest user to have access to a PSK WLAN, the key must be given to that guest. Once the guest departs, this shared secret must be changed on all devices to ensure adequate security for the PSK WLAN.

37

Physical security includes protecting assets using physical means.

38

List the three types of MAC frames defined by the 802.11 standard.

39

What type of RFID tag operates at 2.45 GHz?
