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

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

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

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
