Answer: Lattice-based, non-discretionary
Explanation: Lattice-based access control is a form of non-discretionary access control in which users are assigned a matrix of authorizations for particular areas of access. Lattice-based access control are usually used to restrict or define the level of authorization granted to a subject which may be an individual, organization or group or the that given to the object which may include applications and computers.It utilizes a non-discretionary approach whereby the defined access is uniformly enforced across all subjects and objects within the confines of an information system.
Answer:
hour = float(input("Enter hour:"))
minute = float(input("Enter minute:"))
second = float(input("Enter second:"))
am_pm = input ("Enter AM or PM:")
if am_pm == "AM":
if hour == 12:
hour = 0
seconds_since_midnight = ((3600 * hour) +(minute *60) + second)
elif am_pm == "PM":
seconds_since_midnight = ((3600 * (hour+12)) +(minute *60) + second)
print("Seconds since midnight:", int(seconds_since_midnight))
Explanation:
The point here is when PM is chosen, you need to add 12 to the hour. I added <em>elif</em> part to satisfy this. Moreover, since the output is in integer format, you may need to apply type casting for <em>seconds_since_midnight</em> variable.
Answer:
b. The Hello timer as configured on the root switch.
Explanation:
There are differrent timers in a switch. The root switch is the only forwarding switch in a network, while non root switches blocks traffic to prevent looping of BPDUs in the network. Since the root switch is the only forwarding switch, all timing configuration comes from or is based on the configuration in the root.
The hello timer is no exception as the nonroot switch only sends 802.1D DTP hello BPDU messages forwarded to it by the root switch and its frequency depends on the root switch hello timer.
Answer:
This is a multicolinearity problem and the student should determine the variable(s) that cause(s) the problem and remove it.
Explanation:
This information means that there exists a linear combination between the independent variables. The problem might have developed due to multicolinearity producing almost perfectly linearly dependent columns.
This could also be as a results of single matrix created when the student use an incorrect indicator variables and included an additional indicator column which created linearly dependent columns.
