1. A. Enable mutual redistribution between OSPF and RIP on one border router.
2. B. Enable mutual redistribution between OSPF and RIP on Router A and Router B using route tags.
3. C. Increase the administrative distance to 130 for the OSPF external prefixes on Router A and Router B.
4. D. Implement an ACL on Router A and Router B to prevent OSPF external routes from being installed in the OSPF database.
5. E. Filter external routes on Router A and Router B based on route tags.

Correct Answer: BCE

Which option describes a design benefit of root guard?

1. A. It prevents switch loops caused by unidirectional point-to-point link condition on Rapid PVST+ and MST.
2. B. It prevents switch loops by detecting on one-way communications on the physical port.
3. C. It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.
4. D. It makes the port go immediately into the forwarding state after being connected.
5. E. It prevents switched traffic from traversing suboptimal paths on the network.
6. F. It does not generate a spanning-tree topology change upon connecting and disconnecting a station on a port.

Correct Answer: E

An operations engineer asks for your help with a new switching deployment. The engineer confirms
that STP is enabled on an edge switch, and a particular port is connected to another switch. The switch is not receiving configuration BPDUs, although it appears that everything is functioning correctly in the network. What is the design explanation?

1. A. Bridge Assurance is enabled on the port
2. B. Storm control broadcast is enabled on the port
3. C. REP is enabled on the port
4. D. BPDU Guard is enabled on the port

Correct Answer: C

Refer to the Exhibit.
