Q51. Exhibit: (Refer the EXHIBIT given below.)

Both End Stations and both Data Link Switching Plus (DLSW+) routers are in a
common VLAN.

The DLSW+ routers have peers to the Channel Interface Processor (CIP) router. Both
DLSW+ routers show they can reach the Host via 4000.2feb.0001. Users are having
trouble maintaining their SNA sessions. Their IP connectivity is unaffected.

What DLSW+ feature would most likely fix the problem?

350-001
24
A. Load Balancing.
B. Duplicate Path Bias.
C. Static Paths.
D. Ethernet Redundancy.

Answer: A

E. Order

Answer: A


Q54. Considering OSPF where a binding between an interface and an area has been
done, what is the effect of defining such an interface as passive?

A. OSPF will not form any adjacency out if that interface but it will accept the
routing updates from the neighbors.
B. OSPF will form all the available adjacencies out of that interface but it wont install
any of the learned routes in the local routing table.
C. OSPF will not form any adjacency out of that interface.
D. OSPF will behave as a passive adjacency at the requests coming from neighbors,
lying out of the interface, ignoring all the incoming requests.
E. None of the above.

Answer: C


Q55. When connecting two different VLAN Trunk Protocol domains together via and
