and monitoring of network user behavior, and also by keeping a record of every
access connection and device configuration change across the network?
authentication
accreditation
* accounting
authorization
2 Which two characteristics of network traffic are being monitored if a network
technician configures the company firewall to operate as a packet filter? (Choose
two.)
applications
physical addresses
packet size
* ports
* protocols
3 A server log includes this entry: User student accessed host server ABC using
Telnet yesterday for 10 minutes. What type of log entry is this?
authentication
authorization
* accounting
accessing
4 Which three protocols describe methods that can be used to secure user data for
transmission across the internet? (Choose three.)
SMTP
* IPSEC
* SSL
* HTTPS
FTP
TFTP

5 A network administrator is assigning network permissions to new groups of
users and employing the principle of least privilege. Which two actions should the
administrator take? (Choose two.)
* Provide users with only the access to resources required to do their jobs.
* Provide the minimum level of permissions required for users to do their jobs.
Remove all permissions from the users and grant permissions as they are
requested.
Allow users to decide how much permission they need to accomplish their job
tasks.
Provide full access to the users and gradually remove privileges over time.
6 Which of the following does SNMP use to hold information collected about the
network?
network management station
network management database
* management information base
database information agent
7 What is the term for the public network between the boundary router and the
firewall?
"clean" LAN
intranet
* DMZ
extranet
8 What two measures help to verify that server backups have been reliably
completed? (Choose two.)
* reviewing backup logs
performing trial backups
performing full backups only
replacing tape backup with hard disk-based backup
* using an autoloader when backups require more than one tape
9 A company wants to configure a firewall to monitor all channels of
communication and allow only traffic that is part of a known connection. Which
firewall configuration should be deployed?

packet filtering
proxy
* stateful packet inspection
stateless packet inspection
10 What AAA component assigns varying levels of rights to users of network
resources?
auditing
accounting
* authorization
access control
authentication
acknowledgement
11 A hacker has gained access to sensitive network files. In analyzing the attack, it
is found that the hacker gained access over a wireless segment of the network. It
is further discovered that the only security measure in place on the wireless
network is MAC Address Filtering. How is it likely that the hacker gained access
to the network?
The hacker used a software tool to crack the shared hexadecimal wireless key.
* The hacker obtained the MAC address of a permitted host, and cloned it on his
wireless laptop NIC.
The attacker mounted a denial of service attack to overwhelm the firewall before
penetrating the wireless LAN.
The hacker gained wireless access to the MAC address database and added his
own MAC address to the list of permitted addresses.
12 Which three items are normally included when a log message is generated by a
syslog client and forwarded to a syslog server? (Choose three.)
* date and time of message
* ID of sending device
length of message
* message ID
checksum field
community ID

13 Which benefit does SSH offer over Telnet when remotely managing a router?
* encryption
TCP usage
authorization
connection using six VTY lines
14 Which three protocols are used for in-band management? (Choose three.)
FTP
* HTTP
* SNMP
* Telnet
TFTP
DHCP
15 Before a technician upgrades a server, it is necessary to back up all data.
Which type of backup is necessary to ensure that all data is backed up?
daily
differential
* full
incremental
partial
16 Which means of communication does an SNMP network agent use to provide
a network management station with important but unsolicited information?
query
broadcast
ICMP ping
* trap
poll
17 When is the use of out-of-band network management necessary?
when a server needs to be monitored across the network
* when the management interface of a device is not reachable across the network
when enhanced monitoring features are required to gain an overall view of the
entire network
when it is desirable to use the information that is provided by SNMP

18 What is the advantage of using WPA to secure a wireless network?
It uses a 128-bit pre-shared hexadecimal key to prevent unauthorized wireless
access.
* It uses an advanced encryption key that is never transmitted between host and
access point.
It is supported on older wireless hardware, thus providing maximum compatibility
with enterprise equipment.
It requires the MAC address of a network device that is requesting wireless access
to be on a list of approved MAC addresses.
19 What network layer security protocol can secure any application layer protocol
used for communication?
HTTPS
IMAP
FTPS
* IPSEC
TLS
20 What are two potential problems with using tape media to back up server data?
(Choose two.)
Tape is not a cost-effective means of backing up data.
Data tapes are difficult to store offsite.
* Data tapes are prone to failure and must be replaced often.
* Tape drives require regular cleaning to maintain reliability.
Backup logs are not available with tape backup solutions.
