Question:2
At which layer of the OSI model does the Spanning Tree Protocol (STP) operate at?
A. Layer 5
B. Layer 4
C. Layer 3
D. Layer 2
E. Layer 1
Answer: D

Question:3
In computer networking a multicast address is an identifier for a group of hosts that have joined a multicast group. Multicast addressing can be used in the Link Layer (OSI Layer 2), such as Ethernet Multicast, as well as at the Internet Layer (OSI Layer 3) as IPv4 or IPv6 Multicast. Which two descriptions are correct regarding multicast addressing?
A. The first 23 bits of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
B. The last 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
C. To calculate the Layer 2 multicast address, the host maps the last 23 bits of the IP address into the last 24 bits of the MAC address. The high-order bit is set to 0.
D. The first 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
Answer: C, D

Question:4
EIGRP is being used as the routing protocol on the PassGuide network. While troubleshooting some network connectivity issues, you notice a large number of EIGRP SIA (Stuck in Active) messages. What causes these SIA routes? (Select two)
A. The neighboring router stops receiving ACK packets from this router.
B. The neighboring router starts receiving route updates from this router.
C. The neighboring router is too busy to answer the query (generally caused by high CPU utilization).
D. The neighboring router is having memory problems and cannot allocate the memory to process the query or build the reply packet.
Answer: C, D

Question:5

A. SwitchPassGuide2 is configured for only VLAN1.
B. SwitchPassGuide2 is a VTP server in a different domain.
C. SwitchPassGuide2 is a VTP server in the PASSGUIDE domain.
D. SwitchPassGuide2 is not a VTP domain.
E. SwitchPassGuide2 has a lower VTP configuration revision number than the current VTP revision.
F. SwitchPassGuide2 has a higher VTP configuration revision number than the current VTP revision.
Answer: A, C, F

Question:6
You need to troubleshoot an issue on the PassGuide switched LAN. When you issue a command “show port 3/1” on a PassGuide switch, you observe the Giants column has a non-zero entry. What could cause this?

B. Misconfigured NIC
C. User configuration
D. IEEE 802.1Q
E. None of the other alternatives apply
Answer: D

Question:7
What should you do to reduce spanning-tree protocol BPDU traffic during extended periods of instability in your VLANs?

B. Set forward delay and max-age timers to the maximum possible values.
C. None of the choices.
D. Change the router VTP server mode.
E. Disable the root bridge
Answer: B
