Active tags have batteries whereas passive tags receive their energy from the reader when the reader interrogates the device. As you would expect, the passive tags are cheaper but have a range of only a few meters and the active tags are more expensive but can transmit up to a hundred meters.)

Q19) Which of the following offers the most flexibility in reacting to security events?

A) Cameras

B) Security guards

C) Motion sensors

D) Intrusion prevention systems

Show Answer

Answer :  (B) Security guards. (Security guards offer the most flexibility in reacting to whatever occurs. Guards can use discriminating judgment based on the situation, which automated systems cannot do. This makes guards an excellent addition to the layers of security you should be trying to create.)

Q20) Which of the following statements is false with respect to safes?

A) All safes are fireproof.

B) United Laboratories (UL) assigns ratings to safes that you can use to assess the suitability of the safe

C) Those that are fire resistant will protect a document from being destroyed

D) When considering a safe, you should focus on two items: the ease with which the safe can be compromised and the ability of the safe to withstand a fire

Show Answer

Answer :  (A) Security guards. (Security guards offer the most flexibility in reacting to whatever occurs. Guards can use discriminating judgment based on the situation, which automated systems cannot do. This makes guards an excellent addition to the layers of security you should be trying to create.)

Q21) Which of the following is true of the requirements to use SSL on a website?

A) The web server must have a certificate

B) The client must have a certificate

C) The web server and the client must have a certificate

D) Neither the web server nor the client must have a certificate

Show Answer

Answer :  (A) The web server must have a certificate. (SSL is related to a PKI in that a certificate is required on the server end and optionally can be used on the client end of an SSL communication.)

Q22) You have two devices that are connected to the same switch with IP addresses in the same network. After placing the two devices in separate VLANs, they can no longer ping one another. At what layer of the OSI model are the VLANs providing separation?

A) Network

B) Data link

C) Session

D) Transport

Show Answer

Answer :  (B) Data link. (Devices in different VLANs usually have IP addresses in different IP subnets. However, even if they have IP addresses in the same subnet, communication cannot occur without routing—if they reside in different VLANs—because VLANs separate devices at Layer 2, or the Data Link layer, of the OSI model.)

Q23) Which of the following is not true of an HIDS?

A) A high number of false positives can cause a lax attitude on the part of the security team

B) An HIDS cannot address authentication issues

C) Encrypted packets cannot be analyzed

D) An HIDS monitors all traffic that goes through it looking for signs of attack on any machine in the network

Show Answer

Answer :  (A) A high number of false positives can cause a lax attitude on the part of the security team. (When discussing network security, an endpoint is any point of entry into the network. A typical example of an endpoint is a laptop connected to the network with a remote access connection. Therefore, the process of providing endpoint security is the process of ensuring that every endpoint (including servers) has been secured in the same way in which you would secure the network gateway.)

Q24) Which of the following can read the individual commands of the protocols that are being served?

A) Stateful firewall

B) Packet filtering firewall

C) Application-level proxy

D) Host-based firewall

Show Answer

Answer :  (C) Application-level proxy. (The proxy function can occur at either the application level or the circuit level. Application-level proxy functions read the individual commands of the protocols that are being served. This type of server is advanced and must know the rules and capabilities of the protocol used.)

Q25) In which of the following devices are records kept using a table that tracks every communications channel?

A) Stateful firewall

B) Packet filtering firewall

C) Application-level proxy

D) Host-based firewall

Show Answer

Answer :  (A) Stateful firewall. (In stateful inspection (or stateful packet filtering), records are kept using a state table that tracks every communications channel.)

Q26) Which statement is false with respect to router ACLs?

A) The order of the rules is important

B) An implied deny all rule is located at the end of all ACLs

C) It is possible to log all traffic that meets any of the rules

D) All rules in the list are considered before the traffic is allowed

Show Answer

Answer :  (D) All rules in the list are considered before the traffic is allowed. (If traffic matches a rule, the action specified by the rule will be applied, and no other rules will be read.)

Q27) Which of the following is true of the requirements to use SSL on a website?

A) The web server must have a certificate

B) The client must have a certificate

C) The web server and the client must have a certificate

D) Neither the web server nor the client must have a certificate

Answer :  (A) Set the minimum number of MAC addresses that can be seen on a port. (It is not possible to specify a minimum number of MAC addresses allowed on a port.)

Q29) Which of the following would Joe use to encrypt a message that only Sally could decrypt?

A) Joe’s private key

B) Sally’s private key

C) Joe’s public key

D) Sally’s public key

Show Answer

Answer :  (D) Sally’s public key. (To provide encryption, the data is encrypted with the receiver’s public key, which results in cipher text that only his private key can decrypt.)

Q30) You have two devices that are connected to the same switch with IP addresses in the same network. After placing the two devices in separate VLANs, they can no longer ping one another. At what layer of the OSI model are the VLANs providing separation?

A) Network

B) Data link

C) Session

D) Transport

Show Answer

Answer :  (B) Data link. (Devices in different VLANs usually have IP addresses in different IP subnets. However, even if they have IP addresses in the same subnet, communication cannot occur without routing—if they reside in different VLANs—because VLANs separate devices at Layer 2, or the Data Link layer, of the OSI model.)

Q31) Which of the following has lost favor to SSH because it sends data—including passwords— in plain-text format?

A) POP3

B) Telnet

C) RDP

D) IMAP

Show Answer

Answer :  (B) Telnet. (Telnet is a protocol that functions at the Application layer of the OSI model, providing terminal-emulation capabilities. Telnet runs on port 23, but has lost favor to SSH because Telnet sends data—including passwords—in plain-text format.)

Q32) If a process fails, most operating system write the error information to a ______

A) New file

B) Another running process

C) Log file

D) None of the mentioned

Show Answer

Answer :  (C) log file. ( If a process fails, most operating systems write the error information to a log file. Log file is examined by the debugger, to find out what is the actual cause of that particular problem. Log file is useful for system programmers for correcting errors. )
