Answer of CCNA Discovery : Version 4.1 by-NoNaMeZzz-

1
Which AAA service reduces IT operating costs by providing detailed reporting 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 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

3
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.

4
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

5
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

6
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

7
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

8
Which three protocols are used for in-band management? (Choose three.)

FTP

HTTP

*SNMP

*Telnet

*TFTP

DHCP

9
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.

10
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.

11
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

12
Which benefit does SSH offer over Telnet when remotely managing a router?

*encryption

TCP usage

authorization

connection using six VTY lines

13
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

14
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.

15
What is the term for the public network between the boundary router and the firewall?

“clean” LAN

intranet

*DMZ

extranet

16
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

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 network layer security protocol can secure any application layer protocol used for communication?

HTTPS

IMAP

FTPS

*IPSEC

TLS

19
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

20
What AAA component assigns varying levels of rights to users of network resources?

auditing

accounting

authorization

access control

*authentication

acknowledgement
