Cisco CCNA Solved MCQ

Cisco CCNA Solved MCQ contain set of 10 MCQ questions for Cisco CCNA MCQ which will help you to clear beginner level quiz.



1) Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally:monitor session 2 filter vlan 1 – 8, 39, 52. What is the result of the implemented command?
A. All VLAN traffic is sent to the SPAN destination interface.
B. Traffic from VLAN 4 is not sent to the SPAN destination interface.
C. Filtering a trunked SPAN port effectively disables SPAN operations for all VLANs.
D. The trunk’s native VLAN must be changed to something other than VLAN 1.
E. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.
Answer : E
 
2) A network engineer must improve bandwidth and resource utilization on the switches by stopping the inefficient flooding of frames on trunk ports where the frames are not needed. Which Cisco IOS feature can be used to achieve this task?
A. VTP pruning
B. access list
C. switchport trunk allowed VLAN
D. VLAN access-map
Answer : A
 
3)Which command does a network engineer use to verify the spanning-tree status for VLAN 10?
A. switch# show spanning-tree vlan 10
B. switch# show spanning-tree bridge
C. switch# show spanning-tree brief
D. switch# show spanning-tree summary
E. switch# show spanning-tree vlan 10 brief
Answer: A
 
4) After implementing VTP, the extended VLANs are not being propagated to other VTP switches. What should be configured for extended VLANs?
A. VTP does not support extended VLANs and should be manually added to all switches.
B. Enable VTP version 3, which supports extended VLAN propagation.
C. VTP authentication is required when using extended VLANs because of their ability to cause network instability.
D. Ensure that all switches run the same Cisco IOS version. Extended VLANs will not propagate to different IOS versions when extended VLANs are in use.
Answer : C
 
5) A network engineer deployed a switch that operates the LAN base feature set and decides to use the SDM VLAN template. The SDM template is causing the CPU of the switch to spike during peak working hours. What is the root cause of this issue?
A. The VLAN receives additional frames from neighboring switches.
B. The SDM VLAN template causes the MAC address-table to overflow.
C. The VLAN template disables routing in hardware.
D. The switch needs to be rebooted before the SDM template takes effect.
Answer: C
 
6) After UDLD is implemented, a Network Administrator noticed that one port stops receiving UDLD packets. This port continues to reestablish until after eight failed retries. The port then transitions into the errdisable state. Which option describes what causes the port to go into the errdisable state?
A. Normal UDLD operations that prevent traffic loops.
B. UDLD port is configured in aggressive mode.
C. UDLD is enabled globally.
D. UDLD timers are inconsistent.
Answer: B
 
7) In a Cisco switch, what is the default period of time after which a MAC address ages out and is discarded?
A. 100 seconds
B. 180 seconds
C. 300 seconds
D. 600 seconds
Answer: C
 
8) Which option describes a limitation of LLDP?
A. LLDP cannot provide information about VTP.
B. LLDP does not support TLVs.
C. LLDP can discover only Windows servers.
D. LLDP can discover up to two devices per port.
Answer : A
 
9) A network engineer is setting up a new switched network. The network is expected to grow and add many new VLANs in the future. Which Spanning Tree Protocol should be used to reduce switch resources and managerial burdens that are associated with multiple spanning-tree instances?
A. RSTP
B. PVST
C. MST
D. PVST+
E. RPVST+
Answer: C
10) Which statement about Cisco devices learning about each other through Cisco Discovery Protocol is true?
A. Each device sends periodic advertisements to multicast address 01:00:0C:CC:CC:CC.
B. Each device broadcasts periodic advertisements to all of its neighbors.
C. Each device sends periodic advertisements to a central device that builds the network topology.
D. Each device sends periodic advertisements to all IP addresses in its ARP table.
Answer A
