2 Refer to the graphic. If the switches are new and have been cabled as shown, which switch will become the root bridge? *** SC CE JB JP JN cannot be determined from the information given
3 A switch is operating in VTP client mode. What is true about the operations that can be performed by the switch? VLANs that are created are not included in advertisements. *** It can only adopt VLAN changes advertised from a VTP server. It advertises topology changes out all trunk ports. It can modify existing VLANs, but can not create new ones. It can create and modify VLANs, but can not delete existing ones.
4 Why would a network administrator choose to enable authentication for OSPF exchanges? (Choose two.) *** to prevent routing information from being falsified to reduce OSPF information exchange overhead to assure that OSPF routing information takes priority over RIP or IGRP updates to encrypt routing tables to prevent unauthorized viewing *** to ensure that routing information comes from a valid source
1 Refer to the exhibit. A network administrator needs to add IP phones to the network. To which devices should the IP phones connect?
AS1 and AS2
DS1 and DS2 DS1, DS2, and CS1 AS1, AS2, DS1, and DS2 2 A wireless client is attempting to establish a connection with a wireless access point. What process does the client use to discover the access points which are available to it?
probing
beaconing association authentication 3 Which statement is correct about STP architecture?
Spanning Tree Protocol will guarantee a loop free Layer 2 topology.
Spanning Tree Protocol guarantees the shortest path to destination networks. The switch with the highest priority will be assigned the lowest BID in the root election. The first step in the spanning-tree election process is to determine the root port. To select designated ports, the spanning-tree algorithm must determine the longest contiguous path from the root bridge. 4 Refer to the exhibit. Users A and B are reporting intermittent connectivity problems. Pre-installation surveys showed strong signal strength from the AP locations to the client locations. Outside electrical interference has been eliminated. What will fix the problem? Relocate the APs closer to each other. Increase the distance between the clients.
Change the channel on AP-B to 6 or 11.
Place AP-A and AP-B on the same wireless channel. 5 RSTP is enabled in a switched network that is active and converged. Which switch port type assumes a discarding state on non-root switches? root port edge port
1 Which value determines if a switch becomes the central point of reference in the spanning tree topology? lowest bridge ID highest revision number lowest numeric IP address highest numeric MAC address
2
Refer to the exhibit. What is the purpose of the configuration commands that are shown? to activate port Fa0/10 to make the port a member of VLAN 30 to activate port security on port Fa0/10 to add VLAN 30 to the trunk that is connected to port Fa0/10
3 Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/switch SW1? Host A remains a member of VLAN 10, because the router is routing traffic between VLANs. Host A is no longer a member of VLAN 10, because port Fa0/3 has been manually assigned to VLAN 30. Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for the port. Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network. Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now a member of VLAN 1.
Refer to the exhibit. An administrator documented the output of a CAM table from an Ethernet switch as shown. What action will the switch take when it receives the frame shown at the bottom of the exhibit?
discard the frame forward the frame out port 2 forward the frame out port 3 forward the frame out all ports
forward the frame out all ports except port 3
add station 00-00-3D-1F-11-05 to port 2 in the forwarding table
2
Refer to the exhibit. An administrator issues the commands as shown on SwitchB. What is the result for port Fa0/22?
The port is disabled. Security is enabled on the port. The port becomes a trunk port. The port is now a member of the default VLAN.
3 What is one reason that SSID cloaking is not considered an effective security measure for a wireless network?
The SSID is not required to connect to a wireless network. The SSID is broadcast in probe messages from clients that are looking for the AP. The SSID is the same as the AP MAC address, which is sent in every message. An attacker can spoof the SSID simply by using an SSID of NULL in all messages.
1. What will a wireless client transmit to discover the available WLAN networks? probe request
2. Which function is provided by a wireless access point? converts data from 802.11 to 802.3 frame encapsulation
3. Why is security so important in wireless networks? Wireless networks broadcast data over a medium that allows easy access.
4. Refer to the exhibit. When configuring the wireless access point, which setting does the network administrator use to configure the unique identifier that client devices use to distinguish this wireless network from others? Network Name (SSID)
5. Which access method does a wireless access point use to allow for multiple user connectivity and distributed access? CSMA/CA
1. Refer to the exhibit. What two conclusions can be drawn from the output that is shown? (Choose two.) Both of the directly connected routes that are shown will share the same physical interface of the router. Inter-VLAN routing between hosts on the 172.17.10.0/24 and 172.17.30.0/24 networks is successful on this network.
2. A router has two FastEthernet interfaces and needs to connect to four VLANs in the local network. How can this be accomplished using the fewest number of physical interfaces without unnecessarily decreasing network performance? Implement a router-on-a-stick configuration.
3. What is important to consider while configuring the subinterfaces of a router when implementing inter-VLAN routing? The IP address of each subinterface must be the default gateway address for each VLAN subnet.
4. Refer to the exhibit. PC1 has attempted to ping PC2 but has been unsuccessful. What could account for this failure? The encapsulation command on the R1 F0/0.3 interface is incorrect.
5. What distinguishes traditional routing from router-on-a-stick? Traditional routing uses one port per logical network. Router-on-a-stick uses subinterfaces to connect multiple logical networks to a single router port.
1. What three link types have been defined for Rapid Spanning-Tree Protocol? (Choose three.) shared edge-type point-to-point
2. What Rapid Spanning Tree Protocol (RSTP) role is assigned to the forwarding port elected for every switched Ethernet LAN segment? designated
3. How can a network administrator influence which STP switch becomes the root bridge? Set the switch priority to a smaller value than that of the other switches in the network.
4. Refer to the exhibit. What can be determined from the output shown? The priority was statically configured to identify the root.
5. Which three statements are accurate regarding RSTP and STP? (Choose three.) Both RSTP and STP use the portfast command to allow ports to immediately transition to forwarding state. Configuration commands to establish primary and secondary root bridges are identical for STP and RSTP. Because of the format of the BPDU packet, RSTP is backward compatible with STP.
1. Which statement is true when VTP is configured on a switched network that incorporates VLANs? VTP dynamically communicates VLAN changes to all switches in the same VTP domain.
2.What are two features of VTP client mode operation? (Choose two.) unable to add VLANs can forward VLAN information to other switches in the same VTP domain
3. Which three VTP parameters must be identical on all switches to participate in the same VTP domain? (Choose three.) domain name domain password version number
4. What does a client mode switch in a VTP management domain do when it receives a summary advertisement with a revision number higher than its current revision number? It issues an advertisement request for new VLAN information.
5. Refer to the exhibit. The switches in the exhibit are connected with trunks within the same VTP management domain. Each switch is labeled with its VTP mode. A new VLAN is added to Switch3. This VLAN does not show up on the other switches. What is the reason for this? VLANs created on transparent mode switches are not included in VTP advertisements.
1. What switch port modes will allow a switch to successfully form a trunking link if the neighboring switch port is in "dynamic desirable" mode?
on, auto, or dynamic desirable mode
2. Refer to the exhibit. Computer 1 sends a frame to computer 4. On which links along the path between computer 1 and computer 4 will a VLAN ID tag be included with the frame?
C, E
3. Refer to the exhibit. The exhibited configurations do not allow the switches to form a trunk. What is the most likely cause of this problem?
The trunk cannot be negotiated with both ends set to auto.
4. What must the network administrator do to remove Fast Ethernet port fa0/1 from VLAN 2 and assign it to VLAN 3?
Enter the switchport access vlan 3 command in interface configuration mode.
5. Which two statements describe the benefits of VLANs? (Choose two.)
VLANs improve network security by isolating users that have access to sensitive data and applications. VLANs divide a network into smaller logical networks, resulting in lower susceptibility to broadcast storms..
