Question 1

Which of the following is not a secured mail transferring methodology?&#10;A)pop3&#10;B)ssmtp&#10;C)mail using pgp&#10;D)s/mime

Accepted Answer

POP3 (Post Office Protocol 3) is a standard mail protocol used to retrieve emails from a mail server to a mail client (such as Outlook or Thunderbird) over an Internet connection. It does not inherently include encryption or secure methods for transferring mail, unlike SSMTP (Secure Simple Mail Transfer Protocol), PGP (Pretty Good Privacy), and S/MIME (Secure/Multipurpose Internet Mail Extensions), which are designed to secure emails through encryption and secure connections.

Question 2

__________ is used for encrypting data at network level.&#10;A)ipsec&#10;B)https&#10;C)smtp&#10;D)s/mime

Accepted Answer

IPsec (Internet Protocol Security) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. It operates at the network layer, allowing it to secure all traffic over an IP network.

Question 3

PGP encrypts data by using a block cipher called ______&#10;A)international data encryption algorithm&#10;B)private data encryption algorithm&#10;C)internet data encryption algorithm&#10;D)local data encryption algorithm

Accepted Answer

PGP (Pretty Good Privacy) uses the International Data Encryption Algorithm (IDEA) for encrypting data, which is a block cipher.

Question 4

When were VPNs introduced into the commercial world?&#10;A)early 80's&#10;B)late 80's&#10;C)early 90's&#10;D)late 90's

Accepted Answer

VPNs were introduced into the commercial world in the late 1990s, as the technology became more accessible and the internet started to become widely used for business purposes.

Question 5

What protocol is NOT used in the operation of a VPN?&#10;A)pptp&#10;B)ipsec&#10;C)ymum&#10;D)l2tp

Accepted Answer

YMUM is not a recognized protocol used in the operation of a VPN. PPTP, IPsec, and L2TP are all well-known protocols used for establishing VPN connections.

Question 6

Which of the following statements is NOT true concerning VPNs?&#10;A)financially rewarding compared to leased lines&#10;B)allows remote workers to access corporate data&#10;C)allows lan-to-lan connectivity over public networks&#10;D)is the backbone of the internet

Accepted Answer

VPNs (Virtual Private Networks) are not the backbone of the internet. The backbone of the internet refers to the principal data routes between large, strategically interconnected networks and core routers on the internet. VPNs, on the other hand, are used to create secure connections over the internet or other public networks for the purpose of privacy and security.

Question 7

Traffic in a VPN is NOT ____________&#10;A)invisible from public networks&#10;B)logically separated from other traffic&#10;C)accessible from unauthorized public networks&#10;D)restricted to a single protocol in ipsec

Accepted Answer

Traffic in a VPN is invisible from public networks, logically separated from other traffic, and restricted to a single protocol in IPsec. It is not accessible from unauthorized public networks.

Question 8

Which layer 3 protocols can be transmitted over an L2TP VPN?&#10;A)only ip&#10;B)only ipx&#10;C)only icmp&#10;D)ip and ipx

Accepted Answer

L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide encryption or confidentiality by itself. L2TP allows the transmission of packets of multiple protocols, making it versatile. Both IP (Internet Protocol) and IPX (Internetwork Packet Exchange) can be transmitted over an L2TP VPN, making it suitable for networks that use not just modern IP-based communications but also legacy network protocols.

Question 9

ESP (Encapsulating Security Protocol) is defined in which of the following standards?&#10;A)ipsec&#10;B)pptp&#10;C)ppp&#10;D)l2tp

Accepted Answer

ESP is a component of the IPsec suite for securing Internet Protocol communications by authenticating and encrypting each IP packet in a data stream. IPsec is the standard that defines ESP, not PPTP, PPP, or L2TP.

Question 10

L2F was developed by which company?&#10;A)microsoft&#10;B)cisco&#10;C)blizzard entertainment&#10;D)ietf

Accepted Answer

L2F, or Layer 2 Forwarding Protocol, was developed by Cisco Systems.
