A database can be hacked by-
- a)Exploiting weak passwords
- b)SQL Injection
- c)Delivering a Trojan
- d)All of the above (correct answer)
Answer and explanation
Correct answer: (d) All of the above
Each of the three listed methods can lead to a database compromise, so "All of the above" is the only complete answer.
- Weak or default passwords on database or application accounts can be guessed or brute-forced; OWASP lists permitting weak or well-known passwords as a common authentication failure.
- SQL injection inserts SQL code through an application's input; OWASP notes that a successful exploit can read and modify database data and even run administrative operations.
- A Trojan planted on a database server or an administrator's PC runs hidden malicious code that can steal credentials or copy data out.
Why the other options are wrong
- (a) Exploiting weak passwords: a real route, but choosing it alone ignores (b) and (c).
- (b) SQL Injection: the best-known database attack, but not the only one listed.
- (c) Delivering a Trojan: also a real route, but again only one of three correct choices.
Tip: When every listed option is a genuine attack route, pick "All of the above".

Assume that you want to improve database performance and are willing to see the amount of swap space. Which command can you use in a LINUX OS environment?
- a)lsps -a
- b)swapinfo -m
- c)swapon -s (correct answer)
- d)swap -l and swap -s
Answer and explanation
Correct answer: (c) swapon -s
On Linux, swapon -s (long form --summary) prints a summary of every active swap area, one line per device or swap file, with its type, size, how much is used and its priority. The output is the same as cat /proc/swaps. Red Hat lists both commands as the way to check swap on RHEL systems. free -m also shows the swap total and the amount used.
Why the other options are wrong
- (a)
lsps -a: the IBM AIX command for listing paging spaces; it is not part of Linux. - (b)
swapinfo -m: the HP-UX swap report command; it does not exist on Linux. - (d)
swap -landswap -s: Solaris commands.swap -llists the swap areas andswap -ssummarises swap allocation, but they only exist on Solaris.
Tip: Linux = swapon -s (or cat /proc/swaps, free -m); Solaris = swap -l/swap -s; AIX = lsps -a; HP-UX = swapinfo. Linux commands are lowercase and case-sensitive.

Which of the following is a technique for hiding the internal implementation details of an object?
- a)Encapsulation (correct answer)
- b)Polymorphism
- c)Inheritance
- d)All of the above
Answer and explanation
Correct answer: (a) Encapsulation
Encapsulation hides an object's internals: fields are made private, and outside code may use only the public methods. Because callers interact only with those methods, the internal implementation stays hidden and can change without breaking them. This is called information hiding.
Why the other options are wrong
- (b) Polymorphism: lets one call behave differently for different objects. It is about varying behaviour, not hiding internals.
- (c) Inheritance: lets a subclass reuse a parent's members. It actually makes inherited public and protected members visible to the subclass, so it is not a hiding technique.
- (d) All of the above: only encapsulation is a hiding technique, so "all" is wrong.
Tip: private data + public methods = encapsulation = information hiding. (Abstraction, which shows only the essentials, is a close cousin but is not offered here.)

What is invoked via HTTP on the Web server computer when it responds to requests from a user's Web browser?
- a)A Java application
- b)A Java applet
- c)A Java servlet (correct answer)
- d)None of the above is correct
Answer and explanation
Correct answer: (c) A Java servlet
A Java servlet is a server-side Java component that runs inside the web server's servlet container (e.g. Tomcat). When a browser sends an HTTP request to a URL mapped to the servlet, the container invokes it (for example its doGet() or doPost() method); the servlet runs its logic and writes the HTTP response, usually an HTML page or JSON, back to the browser.
Why the other options are wrong
- (a) A Java application: a standalone program started through its
main()method on the JVM; it is not invoked by the web server for each HTTP request. - (b) A Java applet: embedded in a web page, downloaded and run on the client inside the browser, not on the server.
- (d) None of the above is correct: wrong, because (c) exactly describes the server-side component.
Tip: Servlet = server side (invoked by HTTP requests); Applet = client side (ran in the browser).
Sources: Servlet (Java EE 7 Specification APIs); Applet (Java Platform SE 8)
How does RAID provide data protection?
- a)Using either data mirroring or parity (correct answer)
- b)Using either data mirroring or striping
- c)Using high quality disk drives
- d)Using dedicated data protection hardware
Answer and explanation
Correct answer: (a) Using either data mirroring or parity
RAID protects data through redundancy, in one of two forms:
- Mirroring (RAID 1): every block is written to two disks, so a full copy survives if one disk fails.
- Parity (RAID 3, 4, 5, 6): extra parity blocks, computed by XOR across the data in a stripe, let the contents of a failed disk be rebuilt from the surviving disks.
Either way, the array keeps working after a disk failure.
Why the other options are wrong
- (b) Using either data mirroring or striping: striping on its own (RAID 0) only spreads data for speed and has zero redundancy, so it protects nothing.
- (c) Using high quality disk drives: RAID was designed around inexpensive disks; protection comes from redundant data, not from better drives.
- (d) Using dedicated data protection hardware: RAID can run in software as well; a RAID controller only computes the mirroring or parity, and the protection still comes from that redundancy.
Tip: Protection = mirroring or parity; striping = speed only.
A DNS client is called a_________
- a)DNS updater
- b)DNS resolver (correct answer)
- c)DNS handler
- d)DNS host
Answer and explanation
Correct answer: (b) DNS resolver
DNS is a client-server system. The server side is the name server; the client side is the resolver. RFC 1034 describes resolvers as the programs that sit between user programs and domain name servers: an application asks the resolver for a name, and the resolver sends the queries to name servers, follows referrals if needed, caches the results and returns the IP address. In a PC this is the stub resolver in the operating system; an ISP's recursive resolver plays the same client role toward authoritative servers.
Why the other options are wrong
- (a) DNS updater: Dynamic DNS update is a separate message type for changing zone records; it is not the name of the DNS client.
- (c) DNS handler: Not a DNS term.
- (d) DNS host: Any computer is a host; the word does not name the DNS client component.
Tip: DNS client = resolver; DNS server = name server.

The three different application logic components are which of the following?
- a)Presentation, Client, and Storage
- b)Presentation, Client, and Processing
- c)Presentation, Processing, and Storage (correct answer)
- d)Presentation, Processing, and Network
Answer and explanation
Correct answer: (c) Presentation, Processing, and Storage
In client/server design every application is described by three logic components:
- Presentation logic: input and output with the user (screens, forms, reports), i.e. the user interface.
- Processing logic: the application or business rules that process the data, validate input and handle requests.
- Storage logic: storing and retrieving data, i.e. the DBMS and its data.
Client/server architectures differ only in where these components run: a fat client runs presentation and processing on the client, a thin client runs only presentation, and a three-tier design places each component on its own tier.
Why the other options are wrong
- (a) Presentation, Client, and Storage: "client" is a machine or role in the architecture, not a logic component; processing logic is missing.
- (b) Presentation, Client, and Processing: again lists "client" as if it were logic and leaves out storage logic.
- (d) Presentation, Processing, and Network: the network connects the tiers; it is infrastructure, not one of the application logic components, and storage is missing.
Tip: Application logic = Presentation + Processing + Storage; tiers decide where each one runs.

Database index speeds up-
- a)Select queries
- b)Where clauses
- c)Update query
- d)Both a and b (correct answer)
Answer and explanation
Correct answer: (d) Both a and b
An index speeds up finding rows. Whenever a query has a search condition on an indexed column, as in the WHERE clause of a SELECT, the DBMS can follow the index to the matching rows instead of scanning the table. In a SQLite test on a 1,000-row table, SELECT * FROM emp WHERE name = 'n500' changed from SCAN emp to SEARCH emp USING INDEX emp_name_idx (name=?) once the index existed. So both (a) and (b) describe what an index speeds up.
Why the other options are wrong
- (a) Select queries: True but incomplete; the index works through the search condition, so (d) is the fuller answer.
- (b) Where clauses: True but incomplete for the same reason.
- (c) Update query: Every UPDATE, INSERT and DELETE must also change the index entries, so indexes add write overhead; that is the usual exam point. An UPDATE with a selective WHERE does use the index to find its rows (SQLite planned it as
SEARCH emp USING INDEX), but the write itself becomes more expensive, so speeding up updates is not what an index is for.
Tip: Index → faster searches and reads, slower writes.
Source: PostgreSQL Documentation: Indexes - Introduction
Exam note: An index can also help an UPDATE or DELETE locate its rows, but the paper as printed expects the read-side answer. If the question reappears unchanged, choose (d).
Which of the following indexes is automatically created by the database server when an object is created?
- a)Implicit
- b)Single column
- c)Unique
