Match the description to the correct VLAN type. (Not all options are used.)

Answer 1

default vlan = all switch ports to this vlan, management vlan = an ip address and subnet mask, data vlan = configured to carry, native vlan = carries untagged traffic

Question 2

Refer to the exhibit. A network administrator has connected two switches together using EtherChannel technology. If STP is running, what will be the end result?

Answer 2

STP will block one of the redundant links.

Question 3

What is a secure configuration option for remote access to a network device?

Answer 3

Configure SSH.

Question 4

Which wireless encryption method is the most secure?

Answer 4

WPA2 with AES

Question 5

After attaching four PCs to the switch ports, configuring the SSID and setting authentication properties for a small office network, a technician successfully tests the connectivity of all PCs that are connected to the switch and WLAN. A firewall is then configured on the device prior to connecting it to the Internet. What type of network device includes all of the described features?

Answer 5

wireless router

Question 6

Refer to the exhibit. Host A has sent a packet to host B. What will be the source MAC and IP addresses on the packet when it arrives at host B?

Answer 6

Source MAC: 00E0.FE91.7799
Source IP: 10.1.1.10

Question 7

. Refer to the exhibit. In addition to static routes directing traffic to networks 10.10.0.0/16 and 10.20.0.0/16, Router HQ is also configured with the following command:

ip route 0.0.0.0 0.0.0.0 serial 0/1/1
What is the purpose of this command?

Answer 7

Packets with a destination network that is not 10.10.0.0/16 or is not 10.20.0.0/16 or is not a directly connected network will be forwarded to the Internet.

Question 8

What protocol or technology disables redundant paths to eliminate Layer 2 loops?

Answer 8

STP

Question 9

Refer to the exhibit. Based on the exhibited configuration and output, why is VLAN 99 missing?

Answer 9

because VLAN 99 has not yet been created

Question 10

Which two VTP modes allow for the creation, modification, and deletion of VLANs on the local switch? (Choose two.)

Answer 10

server
transparent

Question 11

Which three steps should be taken before moving a Cisco switch to a new VTP management domain? (Choose three.)

Answer 11

Configure the switch with the name of the new management domain.
Select the correct VTP mode and version.
Reboot the switch.

Question 12

A network administrator is preparing the implementation of Rapid PVST+ on a production network. How are the Rapid PVST+ link types determined on the switch interfaces?

Answer 12

Link types are determined automatically.

Question 13

Refer to the exhibit. All the displayed switches are Cisco 2960 switches with the same default priority and operating at the same bandwidth. Which three ports will be STP designated ports? (Choose three.)

Answer 13

fa0/13
fa0/10
fa0/21

Question 14

How will a router handle static routing differently if Cisco Express Forwarding is disabled?

Answer 14

Ethernet multiaccess interfaces will require fully specified static routes to avoid routing inconsistencies.

Question 15

Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.)

Answer 15

They improve netw​ork security.
They use fewer router resources.
