Refer to the exhibit. As the new network designer for a manufacturing company, you are designing this resilient Ethernet ring for the plant Ethernet network that is connected to the core, which does not use STP.
Both edge ports are on the same switch in a ring segment. There is connectivity between the edge ports throughout the segment, so you create a redundant connection between any two switches in the ring.
Which four options are characteristics of this design? (Choose four.)

• A.If a link fails, then the alternate ports quickly unblock. When the failed ink comes back up, a physically blocked port per VLAN is selected with minimal disruption to the network.
• B.If a link fails, then the alternate portsquickly unblock. Whenthe failed ink comes back up, a logically blocked port per VLAN is selected with minimal disruption to the network.
• C.If VLAN load balancing is configured, then two ports in the segment control the blocked state of VLANs.
• D.If VLAN load balancing is configured, then one port in the segment controls the blocked state of VLANs.
• E.If all ports in the segment are operational, then one port is in the blocked state for each VLAN.
• F.If one or more ports in a segment are not operational, thereby causing a linkfailure, then all ports forward traffic on all VLANs to ensure connectivity.
• G.If all ports in the segment are operational, then two ports are in the blocked state for each VLAN.

Correct Answer: B,C,E,F

Explanation/Reference:
Explanation:
REP segments have thefollowing characteristics:
If all ports in a segment are operational, one port (referred to as the alternate port) is in the blocked

state for each VLAN. If VLAN load balancing is configured, two ports in the segment control the blocked state of VLANs.
If one or more ports in a segment is not operational, and cause a link failure, all ports forward traffic on

all VLANs to ensure connectivity.
In case of a link failure, alternate ports are unblocked as quickly as possible. When the failed link is up,

a logically blocked portper VLAN is selected with minimal disruption to the network.

In a VPLS design solution, why would you use BGP instead of LDP for signaling?

• A.There are no full-mesh pseudowires due to the route reflection feature of BG
• B.BGP supports VPLS interworking
• C.MAC address learning scales better through BGP
• D.Pseudowire configuration overhead is reduced

Refer to the exhibit. This smart city has decided to deploy a converged network for video surveillance and applications for utility services. These new applications are delay-sensitive and require strict convergence times of less than 50 milliseconds. The network is expected to have up to 50 intermediate distribution frames per ring.
Which protocol provides less than 50 milliseconds convergence?

• A.G8032
• B.STP
• C.G 8031
• D.RSTP

• C.Each component can be designed independently for its role.
• D.Each component can be funded by different organizations based on its role.
