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. CDP can be disabled globally or on a specific interface​. The show cdp neighbor detail command will reveal the IP address of a neighbor only if there is Layer 3 connectivity​. Because it runs at the data link layer​, the CDP protocol can only be implemented in switches.

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

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? Change the permission on the file from ro to rw. Edit the configuration file with a text editor. Convert the file system from FAT32 to FAT16. Use the dir command from the router to remove the Windows automatic alphabetization of the files on the flash drive.

Edit the configuration file with a text editor

Which two actions can be taken to prevent a successful attack on an email server account? (Choose two.) Never use passwords that need the Shift key. Limit the number of unsuccessful attempts to log in to the server. Only permit authorized access to the server room. Never allow physical access to the server console. Never send the password through the network in a clear text.

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? SW1 R2 PC2 R1 SW2

R1

Which protocol supports rapid delivery of streaming media? SNMP RTP PoE TCP

RTP

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? H3 is not connected properly to the network. Something is causing a time delay between the networks. Performance between the networks is within expected parameters. Connectivity between H1 and H3 is fine. Something is causing interference between H1 and R1.

Something is causing a time delay between the networks.

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 determine if connectivity can be established from a non-directly connected network. The network administrator suspects a virus because the ping command did not work. The network administrator wants to verify Layer 2 connectivity. The network administrator wants to verify the IP address configured on router R2.

The network administrator wants to verify Layer 2 connectivity.

Which two statements characterize wireless network security? (Choose two.) Using the default IP address on an access point makes hacking easier. Some RF channels provide automatic encryption of wireless data. An attacker needs physical access to at least one network device to launch an attack. Wireless networks offer the same security features as wired networks. With SSID broadcast disabled, an attacker must know the SSID to connect.

Which two statements about a service set identifier (SSID) are true? (Choose two.) tells a wireless device to which WLAN it belongs used to encrypt data sent across the wireless network consists of a 32-character string and is not case sensitive all wireless devices on the same WLAN must have the same SSID responsible for determining the signal strength
