COMPLETE ANSWERS
An organization that uses a client-server model permits remote user machines to access its
network and distributed resources. With this setup, the organization recognizes that remotely
used client machines can become threats.
Which requirement should this company subject its remote clients to in order to secure data and
communications in the system? Correct Answer: Install restricted user-interface mechanisms
and database management systems
A technology-based firm wants to implement secure data communication between secure
desktops to a remote server while keeping reliability as the most important requirement in its
scope.
Which kind of secure data communication should be used within a WAN environment? Correct
Answer: Transmission control protocol (TCP)
A systems developer needs to create a subscription system for a list of known email abuse
sources.
Which solution should be used to create this item? Correct Answer: Blacklist services
Which service manages the monitoring of devices within the application layer? Correct Answer:
Simple network management protocol (SNMP)
A software developer needs to secure emails for a bank using a public-private key system. The
system should include a variety of algorithms that encrypt files and email messages.
Which email security solution should this developer use? Correct Answer: Pretty good privacy
Which service is managed at the transport layer of the TCP/IP stack? Correct Answer: User
datagram protocol (UDP)
Which layer of TCP/IP composes the simplex connectionless protocol user datagram protocol
(UDP)? Correct Answer: Transport
Which layer of the OSI model is affected if a data center experienced a power outage with no
backup power supply? Correct Answer: Physical
Which layer is affected if an organization has weak authentication communication protocols?
Correct Answer: Session
,How would hackers sniff network traffic during an address resolution protocol (ARP) poisoning
attack? Correct Answer: By changing the target computer's ARP cache with a forged ARP
request
A consultant explains that there is no mechanism within internet control message protocol
(ICMP) for the retransmission of lost or damaged packets.
Why are ICMP error messages sent to the host? Correct Answer: They help the sending process
or its human user to diagnose problems.
According to error logs associated with the local area network (LAN), one of the layers of the
OSI model needs to be used to provide error correction.
Which layer should be used? Correct Answer: Transport
A software developer needs to disconnect a transmission control protocol (TCP) session when a
communication session is complete.
What is the first packet that ensures this process? Correct Answer: FIN flagged packet
A software developer establishes a communication between a web server and a web browser
over a network connection.
Which protocol is encapsulated in the transmission control protocol (TCP) to ensure this action?
Correct Answer: Hypertext transfer protocol (HTTP)
Which attack allows an attacker on the same subnet as its victims to eavesdrop on all network
traffic between the victims? Correct Answer: Man-in-the-middle (MITM) attack
Which protocol is used to transmit web page elements from a web server to web browsers?
Correct Answer: Hypertext transfer protocol (HTTP)
Which protocol provides background security support services for IPSec by negotiating,
establishing, modifying, and deleting security associations? Correct Answer: Internet security
association and key management protocol (ISAKMP)
Which approach will detect the presence of rogue wireless access points? Correct Answer:
Operating a wireless intrusion detection system (IDS)
A company needs to securely connect a client with the company's server. The security is handled
by the two hosts and the traffic carried belongs only to the two hosts.
Which interconnection provision should be used between this server and this client? Correct
Answer: Host-to-host virtual private network (VPN)
Two partnering companies are interested in connecting their respective IPSec gateways through a
secure connection.
, Which interconnection is needed to meet this goal? Correct Answer: Site-to-site virtual private
network (VPN)
An organization is interested in implementing a virtual private network (VPN) that will extend
the company's network to all the branches.
What is the appropriate VPN technology to deploy? Correct Answer: Site-to-site VPN
A network administrator needs to maintain a list of destination networks along with metrics of
direction using a protocol service that operates at the network layer.
Which protocol should be used? Correct Answer: Routing information protocol (RIP)
A network administrator is implementing a new virtual private network (VPN) for an
organization. The administrator needs to use a tunneling protocol that protects transmitted traffic
and supports the transmission of multiple protocols at the data link layer in the OSI model.
Which protocol should be used? Correct Answer: Layer 2 tunneling protocol (L2TP)
An institution is using a network application that supports an exchange of files.
Which application layer protocol should be used? Correct Answer: File transfer protocol (FTP)
A school uses a link state routing protocol at the network layer to maintain a topography map of
all connected networks.
Which protocol should be used? Correct Answer: Open shortest path first (OSPF)
An attacker used a packet sniffer to discover the secure service set identifier (SSID) of a wireless
network.
Which approach should be used to secure this network? Correct Answer: Wi-Fi protected access
2 (WPA2)
Which hardening feature should be used to isolate static environments to prevent changes or
exploits from reaching them? Correct Answer: Virtual local area network segmentation
Which hardening feature should be applied to improve security of a wireless network if the pool
of wireless clients is relatively small and static? Correct Answer: Enable media access control
(MAC) filtering
What should a network administrator do to ensure that the server operating system is up to date?
Correct Answer: Install patches
Which form of firewall control is implemented at the Layer 3 level of the OSI model? Correct
Answer: Static packet-filtering firewall
