1 Which two statements about a service set identifier (SSID) are true? (Choose two.)

responsible for determining the signal strength

used to encrypt data sent across the wireless network

all wireless devices on the same WLAN must have the same SSID*

consists of a 32-character string and is not case sensitive

tells a wireless device to which WLAN it belongs*

2 Which type of network attack involves the disabling or corruption of networks, systems, or services?

access attacks

denial of service attacks*

reconnaissance attacks

malicious code attacks

3 Which command will backup the configuration that is stored in NVRAM to a TFTP server?

copy tftp running-config

copy startup-config tftp*

copy running-config tftp

copy tftp startup-config

4  Open the PT Activity. 

How long will a user be blocked if the user exceeds the maximum allowed number of unsuccessful login attempts?

3 minutes*

1 minute

4 minutes

2 minutes

5 Fill in the blank. Do not use abbreviations.

The ”   show version      ” command that is issued on a router is used to verify the value of the software configuration register.

6 What is a security feature of using NAT on a network?

denies all packets that originate from private IP addresses

allows internal IP addresses to be concealed from external users*

denies all internal hosts from communicating outside their own network

allows external IP addresses to be concealed from internal users

7 A network administrator has determined that various computers on the network are infected with a worm. Which sequence of steps should be followed to mitigate the worm attack?

containment, quarantine, treatment, and inoculation

treatment, quarantine, inoculation, and containment

inoculation, containment, quarantine, and treatment

containment, inoculation, quarantine, and treatment*

8 Which WLAN security protocol generates a new dynamic key each time a client establishes a connection with the AP?






Refer to the exhibit. Baseline documentation for a small company had ping round trip time statistics of 36/97/132 between hosts H1 and H3. Today the network administrator checked connectivity by pinging between hosts H1 and H3 that resulted in a round trip time of 1458/2390/6066. What does this indicate to the network administrator?

Something is causing interference between H1 and R1.

H3 is not connected properly to the network.

Performance between the networks is within expected parameters.

Connectivity between H1 and H3 is fine.

Something is causing a time delay between the networks.*

10 When should an administrator establish a network baseline?

when the traffic is at peak in the network

when there is a sudden drop in traffic

at the lowest point of traffic in the network

at regular intervals over a period of time*

11 A ping fails when performed from router R1 to directly connected router R2. The network administrator then proceeds to issue the show cdp neighbors command. Why would the network administrator issue this command if the ping failed between the two routers?

The network administrator wants to verify the IP address configured on router R2.

The network administrator suspects a virus because the ping command did not work.

The network administrator wants to determine if connectivity can be established from a non-directly connected network.

The network administrator wants to verify Layer 2 connectivity.*

12 Which statement is true about CDP on a Cisco device?

To disable CDP globally, the no cdp enable command in interface configuration mode must be used.

The show cdp neighbor detail command will reveal the IP address of a neighbor only if there is Layer 3 connectivity.

CDP can be disabled globally or on a specific interface.*

Because it runs at the data link layer, the CDP protocol can only be implemented in switches.

13 What is the purpose of issuing the commands cd nvram: then dir at the privilege exec mode of a router?

to list the content of the NVRAM*

to clear the content of the NVRAM

to copy the directories from the NVRAM

to direct all new files to the NVRAM

14 A network administrator checks the security log and notices there was unauthorized access to an internal file server over the weekend. Upon further investigation of the file system log, the administrator notices several important documents were copied to a host located outside of the company. What kind of threat is represented in this scenario?

identify theft

data loss

information theft*

disruption of service

15 If a configuration file is saved to a USB flash drive attached to a router, what must be done by the network administrator before the file can be used on the router?

Edit the configuration file with a text editor.*

Use the dir command from the router to remove the windows automatic alphabetization of the files on the flash drive.

Convert the file system from FAT32 to FAT16.

Change the permission on the file from ro to rw.

16 Which network design consideration would be more important to a large corporation than to a small business?

Internet router



low port density switch

17 Which protocol supports rapid delivery of streaming media?






Refer to the exhibit. An administrator is trying to troubleshoot connectivity between PC1 and PC2 and uses the tracert command from PC1 to do it. Based on the displayed output, where should the administrator begin troubleshooting?






19 Which two statements characterize wireless network security? (Choose two.)

Wireless networks offer the same security features as wired networks.

An attacker needs physical access to at least one network device to launch an attack

Using the default IP address on an access point makes hacking easier.*

Some RF channels provide automatic encryption of wireless data.

With SSID broadcast disabled, an attacker must know the SSID to connect.*

20 Which two actions can be taken to prevent a successful attack on an email server account? (Choose two.)

Never send the password through the network in a clear text.*

Never use passwords that need the Shift key.

Never allow physical access to the server console.

Limit the number of unsuccessful attempts to log in to the server.*

Only permit authorized access to the server room.

21 How should traffic flow be captured in order to best understand traffic patterns in a network?

when it is from a subset of users

during low utilization times

when it is on the main network segment only

during peak utilization times*

22 What do WLANs that conform to IEEE 802.11 standards allow wireless user to do?

use wireless mice and keyboards

create a one-to-many local network using infrared technology

use cell phones to access remote services over very large areas

connect wireless hosts to hosts or services on a wired Ethernet network*

23 Fill in the blank.
