Which Cisco switch feature ensures that configured switch edge ports do not cause Layer 2 loops if a port is mistakenly connected to another switch? A. BPDU guard B. extended system ID C. PortFast D. PVST+

A

Which STP priority configuration would ensure that a switch would always be the root switch? A. spanning-tree vlan 10 priority 0 B. spanning-tree vlan 10 priority 61440 C. spanning-tree vlan 10 root primary D. spanning-tree vlan 10 priority 4096

A

To obtain an overview of the spanning tree status of a switched network, a network engineer issues the show spanning-tree command on a switch. Which two items of information will this command display? (Choose two.) A. The root bridge BID. B. The role of the ports in all VLANs. C. The status of native VLAN ports. D. The number of broadcasts received on each root port. E. The IP address of the management VLAN interface.

A & B

*** Refer to the exhibit. A network administrator configured routers R1 and R2 as part of HSRP group 1. After the routers have been reloaded, a user on Host1 complained of lack of connectivity to the Internet The network administrator issued the show standby brief command on both routers to verify the HSRP operations. In addition, the administrator observed the ARP table on Host1. Which entry should be seen in the ARP table on Host1 in order to gain connectivity to the Internet? A. the IP address and the MAC address of R1 B. the virtual IP address and the virtual MAC address for the HSRP group 1 C. the virtual IP address of the HSRP group 1 and the MAC address of R1 D. the virtual IP address of the HSRP group 1 and the MAC address of R2

B

*** Refer to the exhibit. Which protocol information is being displayed in the output? A. FHRP B. GLBP C. HSRP D. VRRP

B

*** Refer to the exhibit. Which trunk link will not forward any traffic after the root bridge election process is complete? A. Trunk1 B. Trunk2 C. Trunk3 D. Trunk4

B

What additional information is contained in the 12-bit extended system ID of a BPDU? A. MAC address B. VLAN ID C. IP address D. port ID

B

What value determines the root bridge when all switches connected by trunk links have default STP configurations? A. VLAN ID B. MAC address C. extended system ID D. bridge priority

B

Which STP port role is adopted by a switch port if there is no other port with a lower cost to the root bridge? A. designated port B. root port C. alternate D. disabled port

B

Which is the default STP operation mode on Cisco Catalyst switches? A. RSTP B. PVST+ C. MST D. MSTP E. Rapid PVST+

B

Which nonproprietary protocol provides router redundancy for a group of routers which support IPv4 LANs? A. HSRP B. VRRPv2 C GLBP D. SLB

B

Which two concepts relate to a switch port that is intended to have only end devices attached and intended never to be used to connect to another switch? (Choose two.) A. bridge ID B. edge port C. extended system ID D. PortFast E. PVST+

B & D

What could be the effect of duplicate unicast frames arriving at a destination device due to multiple active alternative physical paths? A. Frame collisions increase. B. The number of broadcast domains increases. C. Application protocols malfunction. D. The number of collision domains increases.

C

In which two port states does a switch learn MAC addresses and process BPDUs in a PVST network? (Choose two.) A. blocking B. disabled C. forwarding D. learning E. listening

C & D

Which three components are combined to form a bridge ID? A. port ID B. IP address C. extended system ID D. MAC address E. bridge priority F. cost

C & D & E

*** Refer to the exhibit. A network engineer is troubleshooting host connectivity on a LAN that uses a first hop redundancy protocol. Which IPv4 gateway address should be configured on the host? A. 192.168.2.0 B. 192.168.2.1 C. 192.168.2.2 D. 192.168.2.100

D

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Which switch is the root bridge?​ A. Switch_1 B. Switch_2 C. Switch_3 D. Switch_4

D

What is an advantage of PVST+? A. PVST+ requires fewer CPU cycles for all the switches in the network. B. PVST+ reduces bandwidth consumption compared to traditional implementations of STP that use CST. C. PVST+ optimizes performance on the network through autoselection of the root bridge. D. PVST+ optimizes performance on the network through load sharing.

D

Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.) A. static default routes B. implementing VLANs to contain broadcasts C. redundant links between Layer 2 switches D. link-state dynamic routing that provides redundant routes E. removing single points of failure with multiple Layer 2 switches

D & E

*** Match the step number to the sequence of stages that occur during the HSRP failover process. (There are 4 steps) -The new forwarding router assumes both IP and MAC addresses of the virtual router. -The host initiates an ARP request. -The standby router assumes the role of the following router. -The forwarding fails. -The standby router stops seeing hello messages from the following router.

Step 4 not use Step 3 Step 1 Step 2
