Question 1

____ is an industry-standard protocol that simply provides authentication service.&#10;A) TACACS+&#10;B) SSL&#10;C) RADIUS&#10;D) TLS

Accepted Answer

RADIUS (Remote Authentication Dial-In User Service) is an industry-standard protocol that provides authentication and authorization services. It is commonly used for remote access servers, wireless access points, and other network equipment. While TACACS+ (Terminal Access Controller Access Control System Plus) provides authentication, authorization, and accounting services and SSL (Secure Sockets Layer) and TLS (Transport Layer Security) provide encryption and authentication services.

Question 2

The ____ protocol is governed by RFC 2865 and can be used with cross-platform integration.&#10;A) RADIUS&#10;B) TACACS+&#10;C) SSL&#10;D) CHAP

Accepted Answer

The protocol mentioned in the question is RADIUS which is governed by RFC 2865 and is specifically designed for providing authentication, authorization, and accounting (AAA) services. It can be used with cross-platform integration, making it a popular choice in enterprise and service provider networks. TACACS+ is also a AAA protocol, but it is not as widely supported across platforms as RADIUS. SSL is primarily used for securing web traffic, and CHAP is a protocol used for PPP authentication.

Question 3

A computer program that can infect a computer without the knowledge or permission of the user is a(n)____.&#10;A) Worm&#10;B) Macro Virus&#10;C) Logic bomb&#10;D) Virus

Accepted Answer

A virus is a type of malicious software that can infect a computer without the user's knowledge or permission, often attaching itself to legitimate programs or files.

Question 4

The ____ firewall topology consists of a packet filtering router that forwards all incoming packets to the firewall software on a bastion host.&#10;A) packet-filtering router&#10;B) demilitarized zone&#10;C) single-homed bastion&#10;D) dual-homed bastion

Accepted Answer

The single-homed bastion firewall topology involves a packet filtering router that sends all incoming traffic to the firewall software on a single bastion host. The bastion host is typically hardened with additional security mechanisms such as intrusion detection systems (IDS) and is the only point of access to the internal network. This topology provides a strong layer of defense against external threats while still allowing for secure access to internal resources via the bastion host.

Question 5

The Cisco ____ service will examine your router and recommend which services should be disabled.&#10;A) CHAP&#10;B) RADIUS&#10;C) SSH&#10;D) SDM

Accepted Answer

SDM (Security Device Manager) is a GUI tool used to configure routers, and it includes a service called Security Audit, which can examine the router's configuration and recommend which services should be disabled to enhance security. The other options (CHAP, RADIUS, and SSH) are not related to this specific service.

Question 6

A ____ virus is a virus that infects a computer's master boot record.&#10;A) stealth&#10;B) boot-sector&#10;C) polymorphic&#10;D) logic bomb

Accepted Answer

A boot-sector virus infects the master boot record of a computer, which is responsible for loading the operating system. This type of virus can spread quickly by infecting other bootable devices such as floppy disks or USB drives.

Question 7

When a user opens an infected application file or document, a(n) ____ attaches itself to the application and infects other files accessed by the same application.&#10;A) macro virus&#10;B) worm&#10;C) Trojan&#10;D) logic bomb

Accepted Answer

A macro virus is a type of virus that is embedded within a macro, which is a small program that automates tasks within an application, such as Microsoft Excel or Word. When a user opens an infected file that contains macros, the virus attaches itself to the application and can spread to other files accessed by the same application. In this way, the virus can quickly spread throughout a computer or network, causing widespread damage. Worms and Trojans may also spread through infected files, but they do not typically use macros as a method of infection. Logic bombs are a different type of malicious software entirely, and are designed to trigger specific actions when certain conditions are met, rather than spreading to other files.

Question 8

A ____ is a piece of code inserted into a program that will perform specific malicious functions when specified conditions are met.&#10;A) logic bomb&#10;B) Trojan Horse&#10;C) macro virus&#10;D) worm

Accepted Answer

A logic bomb is a type of malicious code or software that is inserted into a program or system, and is designed to execute a specific set of actions when certain conditions or triggers are met. These triggers can be a specific date or time, a certain action taken by the user, or any other pre-determined condition. Logic bombs are often used by hackers or cybercriminals to cause damage to a system or steal data.

Question 9

____ is a means of encrypting a session between two hosts through the use of digital certificates, which are based on asymmetric key encryption.&#10;A) CHAP&#10;B) RADIUS&#10;C) DMZ&#10;D) SSL

Accepted Answer

SSL (Secure Sockets Layer) is a means of encrypting a session between two hosts through the use of digital certificates, which are based on asymmetric key encryption. CHAP (Challenge-Handshake Authentication Protocol) and RADIUS (Remote Authentication Dial-In User Service) are authentication protocols, while DMZ (Demilitarized Zone) is a network security zone.
