Consider the abstract superclass below:
public abstract class Foo
{
private int a;
public int b;
public Foo( int aVal, int bVal )
{
a = aVal;
b = bVal;
} // end Foo constructor
public abstract int calculate();
} // end class Foo
Any concrete subclass that extends class Foo:
1) Must implement a method called calculate.
2) Will not be able to access the instance variable a.
3) Neither (a) nor (b).
4) Both (a) and (b).
Answer:
4) Both (a) and (b).
Explanation:
In addition to regular classes, Java has abstract classes. An abstract class is like a regular class. You can also define fields and methods in an abstract class, while at the same time, you cannot create an object or an instance of an abstract class. Abstract classes are designed to provide basic functionality for derived classes while derived classes required to implement this functionality.
A derived class must override and implement all abstract methods that are in the base abstract class. Therefore answer a (1) is correct.
Access modifier for the field a was private which means it has to be provided with accessor methods to obtain/modify its value. Therefor answer b (2) is correct as well.

You recently completed a network overhaul over the weekend. Everything seems to be functioning properly until you receive a swarm of help desk support requests, all originating from one specific floor in your building. After a few minutes on the phone with those affected, you determine that no one has indicator lights active on their NICs. What is the most likely problem?
Answer:
Network switch has been disconnected or switched off
Explanation:
An organization networking can be done by using several switches, routers, modems, etc. A network switch works between modem and systems, connecting the systems to the network.
A network switch is a multi-port switch that connects multiple devices to the network. mostly every floor has a network switch connected with the floor systems.
When a system is connected to switch, its indicator light on NIC is active. but as per the scenario, no system has active indicator lights on NIC, which means that there is some problem with the switch or switch is powered off.
You have a forest named PLAB and two domains, PLABA and PLABB. You want to add the users from both the domains to a group that should be restricted within the PLABA domain. Which type of group scope should you set for this group?
Global group is also called universal group users.
Explanation:
A network administrator has two domains are such as PLABA AND PLABB. End-user of each domain wants to login both domain PLABA AND PLABB.
Network administrator has created global group accounts user domain and map all the users in the global group user domain. For every user active directory and rights also be mapped. Global group is also called universal group users. Group polices of each user has to be applied and mapped properly.
Once user are mapped and activated user can login from both domain server.

Which of the following commands would instruct OSPF to advertise ONLY the 192.168.10.0/24 network in Area 0?
Answer:
First, you need to start the OSPF process by executing the command:
Router (config)# router ospf {process-ID#}
Then, you have to instruct the router to advertise the networks that are directly linked to it by entering this network command with the area ID number for that network:
Router (config-router)# network {192.168.10.0} {255.255.255.0} area {0}
The command will advertise ONLY the 192.168.10.0/24 is
router ospf <process-id>
network 192.168.10.0 0.0.0.255 area 0
To instruct OSPF to advertise ONLY the 192.168.10.0/24 network in Area 0, use the network command in OSPF router configuration mode.
The specific command use depends on the router's OSPF process.
Assuming you are using Cisco IOS, the command would be:
router ospf <process-id>
network 192.168.10.0 0.0.0.255 area 0
In this command:
<process-id> should be replaced with the OSPF process ID on the router.
`192.168.10.0` is the network address you want to advertise.
`0.0.0.255` is the wildcard mask, which means the network is 192.168.10.0/24 (since 255.255.255.0 is the subnet mask for /24).
`area 0` specifies that the network should be advertised in Area 0, which is the backbone area in OSPF.
This command will advertise ONLY the 192.168.10.0/24 network in Area 0 and no other networks.

Show two ways of bracketing an exposure of f/16 at 1/125 shutter speed. (Copy the two lines below and fill in the blanks for the two alternate exposures for each way. Remember that you need an f-stop and a shutter speed to write an exposure.)
Answer:
Explanation:
If we use bracketing, we must take three pictures of the same place, but we must take it with different exposures.
In this particular example we have an exposure of f/16 at 1/125 shutter speed, first we must take underexposed picture with exposure of f/22 at 1/125 shutter speed or exposure of f/16 at 1/400 shutter speed, then we take an overexposed picture with exposure of f/8 at 1/125 shutter speed or exposure of f/16 at 1/50 shutter speed.
The last step is taking the three pictures and use the option bracketing in an editing photo tool, there are cameras that have this option to take 3 pictures automatically.
The ability for a protocol or program to determine that something went wrong is known as_________.
Answer:
The correct answer to the following question will be Error-detection.
Explanation:
Error-detection: The detection of errors caused during the transmission from the transmitter to the receiver by damage and other noises, known as Error-detection. This error-detection has the ability to resolute if something went wrong and if any error occurs in the program.
There are mainly three types of error-detection, these types can be followed:
Automatic Repeat Request (ARQ)Forward Error CorrectionHybrid SchemesThere are two methods for error-detection, such as:
Single parity checkTwo-dimensional parity checkThe ____ term implies that the type’s data can be accessed only through methods.
A. abstract type library
B. advanced data type
C. abstract definition type
D. abstract data type
Answer:
D. abstract data type
Explanation:
Abstract data type is a data type whose implementation is embedded behind an abstraction. They can be worked via methods and functions but their specification is abstracted.
Lists and Stacks can be given as examples of abstract data types.
Abstract data type can be considered as the opposite of Concrete Data Type (CDT).
Final answer:
The abstract data type (ADT) is the correct term that refers to a type where its data is accessible only through specific methods, providing encapsulation of data.
Explanation:
The abstract data type (ADT) term implies that the type’s data can be accessed only through methods. This encapsulates the data and only allows it to be accessed or manipulated through a defined set of operations. ADTs provide a mathematical model for data types where data and operations are defined independently of any specific implementation.
This abstraction allows for different implementations that can vary internally but share the same external interface. An example of an ADT is a stack, which provides operations such as push, pop, and peek without revealing the underlying data structure, whether it be an array, list, or any other method of internal representation.

D. broadcasts weak microwave signals to create "cells" of mobile coverage
Answer:
The correct answer to the following question is options A, B, and D.
Explanation:
Base Transceiver Station (BTS) is an apparatus that works wireless communication between the network and user equipment (UE - Mobile phones (handset), wireless network computers). Wireless technologies like wi-fi, GSM, CDMA, etc.
Some elements of BTS :
Radio base stationTower/MastDuplexerTransceiver unit (TRU)MicrowaveSo the above are the elements of the BSA, then it also having the characteristics related to these elements like it definitely connects to a cell network, sends phone or mobile phone and microwave signals to cellular providers but it isn't able to send the signals to the recepients.
A Base Transceiver Station (BTS) is connected to a cell tower, sends signals to the provider's Mobile Switching Station (MSS), and broadcasts weak microwave signals.
Explanation:The characteristics of a Base Transceiver Station (BTS) are:
Connected to a cell tower: A BTS is connected to a cell tower, which allows it to transmit and receive signals to and from mobile phones.Sends phone signals to the cellular provider's Mobile Switching Station (MSS): A BTS sends phone signals to the cellular provider's MSS, which handles the routing of calls and messages.Broadcasts weak microwave signals to create "cells" of mobile coverage: A BTS broadcasts weak microwave signals to create cells of mobile coverage, enabling mobile phones to be used while changing location.Host A has IP address/network mask: 192.168.3.222/27
Host B has IP address/network mask: 192.168.3.225/27
Given the information above, it can be inferred that:
Group of answer choices
Both host A and host B are on the same network
Host A and Host B are on different networks
Host A and Host B will have the same routing tables
Host A and Host B will be able to communicate directly without an intervening router.
Answer:
The first option can be inferred.
Explanation:
IP address stands for Internet Protocol Address and is assigned to every device that is connected to a computer network or the internet so that they can be identified and located.
The fact that the IP addresses are starting with 192.168 means that they are private IP addresses and is assigned by the router. Since both host A and host B have IP addresses starting with 192.168, it can be inferred that they are both on the same network.

As the manager for network operations at his company, Shane saw an accountant in the hall who thanks him for keeping the antivirus software up to date. When asked what he means, he mentions one of the IT staff members named Michael called him yesterday and remotely connected to his PC to update the antivirus…but there’s no employee named Michael. What happened?A) IP spoofingB) MAC spoofingC) Man-in-the-middle attackD) Social engineering
Answer:
D. Social engineering.
Explanation:
In IP spoofing, ip packets with a false ip address source is created with the sole intent on impersonating a client system in a network.
MAC (media access control) address spoofing is similar to ip spoofing, but is related to stealing MAC integrity to impersonate a system.
So, man in the middle security attack is very much related to an active member of a company planting security threat codes to gain access to restricted networks.
Social engineering clearly describes this scenario, as the culprit is not a member of company but played on the ignorance of a member.

Answer:
The correct answer to the following question will be option C.
172.16.80.1-172.16.87.254
Explanation:
IP Address: IP Address stands for Internet Protocol Address, a unique numerical label allotted to every computer network that are connected to the network of the computer and communicate through the internet protocol.
An IP address can be separated by periods and having four numbers that are called Octet. Range of IP address can be from 0 to 255.We have to keep the first 21 bits and start setting all from the 22nd bit on to 0 (zero).To get the suitable and the correct range of the address, we add and subtract 1 from the given broadcast address i.e.,172.16.85.0/21.So, option C is the right answer and no other option is usable according to the given explanation and the address given by the administrator.
Which is true about POP3 and IMAP for incoming email?
(a)Both keep email on an email server by default
(b)IMAP keeps email on an email server by default
(c)Neither keep email on an email server by default
(d)POP3 keeps email on an email server by default.
Answer:
Both keep email on an email server by default is true about POP3 and IMAP for incoming email
Explanation:
POP3 and IMAP have used setting parameters for incoming email in MS-outlook and lotus domino to receive emails for the end-user.
Normally pop3 will nor keeps mail in emails in the server. once the end-user receives mails for the specific account it deletes emails from the email server.
But IMAP keeps mail in the email server. So the end-user can retrieve the old emails in case he formatted or lost emails.
But email account has some limitation in size. If it is IMAP setting period cleaning should be done in the email server. If it is not done the end-user will not receive any email unless or until deleting the old emails.
Best method is to have pop3 account. But in pop3 still setting can be done in email server not delete for specific period of time.
