Answer: A
Q6. What is the default value for the errdisable recovery interval in a Cisco switch?
A. 30 seconds
B. 100 seconds
C. 300 seconds
D. 600 seconds
Answer: C
Q7. Which configuration command ties the router hot standby priority to the availability of its interfaces?
A. standby group
B. standby priority
C. backup interface

Answer: D
Q8. Which statement describes what happens when a switch enters dual active recovery mode?
A. The switch shuts down and waits for the VSL link to be restored before sending traffic.
B. All interfaces are shut down in the formerly active virtual switch member, but the new active virtual switch forwards traffic on all links.
C. The switch continues to forward traffic out all links and enables spanning tree on VSL link and all other links to prevent loops.
D. The VSS detects which system was last in active state and shuts down the other switch.
Answer: B
Q9. While working in the core network building, a technician accidently bumps the fiber connection between two core switches and damages one of the pairs of fiber. As designed, the link was placed into a non-forwarding state due to a fault with UDLD. After the damaged cable was replaced, the link did not recover. What solution allows the network switch to automatically recover from such an issue?
A. macros
B. errdisable autorecovery
C. IP Event Dampening
D. command aliases
E. Bidirectional Forwarding Detection
Answer: B
Q10. Which statement about using native VLANs to carry untagged frames is true?
A. Cisco Discovery Protocol version 2 carries native VLAN information, but version 1 does not.
B. Cisco Discovery Protocol version 1 carries native VLAN information, but version 2 does not.
C. Cisco Discovery Protocol version 1 and version 2 carry native VLAN information.
D. Cisco Discovery Protocol version 3 carries native VLAN information, but versions 1 and 2 do not.
Answer: A
Q11. An access switch has been configured with an EtherChannel port. After configuring SPAN to monitor this port, the network administrator notices that not all traffic is being replicated to the management server. What is a cause for this issue?
A. VLAN filters are required to ensure traffic mirrors effectively.
B. SPAN encapsulation replication must be enabled to capture EtherChannel destination traffic.
C. The port channel can be used as a SPAN source, but not a destination.
D. RSPAN must be used to capture EtherChannel bidirectional traffic.
Answer: C
Q12. A network engineer has just deployed a non-Cisco device in the network and wants to get information about it from a connected device. Cisco Discovery Protocol is not supported, so the open standard protocol must be configured. Which protocol does the network engineer configure on both devices to accomplish this?
A. IRDP
B. LLDP
C. NDP
D. LLTD
Answer: B
Q13. If a network engineer applies the command mac-address-table notification mac-move on a Cisco switch port, when is a syslog message generated?
A. A MAC address or host moves between different switch ports.
B. A new MAC address is added to the content-addressable memory.
C. A new MAC address is removed from the content-addressable memory.
D. More than 64 MAC addresses are added to the content-addressable memory.
Answer: A
Q14. Which action allows a network engineer to limit a default VLAN from being propagated across all trunks?
A. Upgrade to VTP version 3 for advanced feature set support.
B. Enable VTP pruning on the VTP server.
C. Manually prune default VLAN with switchport trunk allowed vlans remove.
D. Use trunk pruning vlan 1.
Answer: C
Q15. What happens on a Cisco switch that runs Cisco IOS when an RSTP-configured switch receives 802.1d BPDU?
A. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives an 802.1d BPDU, it responds with an 802.1d BPDU and eventually the two switches run 802.1d to communicate.
B. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it responds with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
C. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU.
D. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
Answer: A
