STP/FHRP Quiz contain set of 10 MCQ questions for STP/FHRP MCQ which will help you to clear beginner level quiz.



1. A network administrator is overseeing the implementation of first hop redundancy protocols. Which two protocols will not be able to function with multivendor devices? (Choose two.)
a)    HSRP

Answers:-1,3 HSRP,GLBP
 
2. During the implementation of Spanning Tree Protocol, all switches are rebooted by the network administrator. What is the first step of the spanning-tree election process?
a)    Each switch with a lower root ID than its neighbor will not send BPDUs.
b)   All the switches send out BPDUs advertising themselves as the root bridge.
c)    Each switch determines the best path to forward traffic.
d)   Each switch determines what port to block to prevent a loop from occurring.
 
Answer:-2
 
3. Which three port states are used by Rapid PVST+? (Choose three.)
a)    Discarding
b)   Blocking
c)    trucking
d)   Listening
e)    Learning
f)     Forwarding
 
Answer:-1, 5& 6
 
4. An administrator is troubleshooting a switch and wants to verify if it is a root bridge. What command can be used to do this?
a)  Show spanning-tree
b)  Show running-config
c)   Show startup-config
d)  Show vlan
 
Answer:-1
 
5. What is an accurate description of redundancy?
a)    Configuring a router with a complete MAC address database to ensure that all frames can be forwarded to the correct destination.
b)   Configuring a switch with proper security to ensure that all traffic forwarded through an interface is filtered.
c)    Designing a network to use multiple virtual devices to ensure that all traffic uses the best path through the internetwork
d)   Designing a network to use multiple paths between switches to ensure there is no single point of failure
 
Answer:-4
 
6. After the election of the root bridge has been completed, how will switches find the best paths to the root bridge?
a)    Each switch will analyze the sum of the hops to reach the root and use the path with the fewest hops.
b)   Each switch will analyze the BID of all neighbors to reach the root and use the path through the lowest BID neighbors.
c)    Each switch will analyze the port states of all neighbors and use the designated ports to forward traffic to the root.
d)   Each switch will analyze the sum of all port costs to reach the root and use the path with the lowest cost.
 
Answer:-4
 
7. When first hop redundancy protocols are used, which two items will be shared by a set of routers that are presenting the illusion of being a single router? (Choose two.)
a)    Hostname
b)   IP address
c)    BID
d)   Static route
e)  MAC address
 
Answer:-2, 5
 
8. Match the step number to the router failover stage in the order that it occurs when a FHRP initiates a router failover process. (Not all options are used.)
Step 1
Step 2
Step 3
a)    The standby router assumes the role of the forwarding router
b)   The standby router receives a down notification
c)    The standby router stops seeing Hello messages from the forwarding router
d)   The forwarding router forwards traffic to the standby router.
e)    The new forwarding router assumes the IP and Mac address of the virtual router.
 
Answers:-3,1&5
