Refer to the exhibit.
A network technician is asked to design a small network with redundancy. The exhibit represents
this design, with all hosts configured in the same VLAN. What conclusions can be made about this
design?
A.
This design will function as intended.
B.
Spanning-tree will need to be used.
C.
The router will not accept the addressing scheme.
D.
The connection between switches should be a trunk.
E.
The router interfaces must be encapsulated with the 802.1Q protocol.
How come the answer is C???
Each interface on a router must be in a different network. If two interfaces are in the same network, the router will not accept it and show error when the administrator assigns it.
After all, router role is to connect different networks, otherwise a switch would be enough.
Network redundancy is primarily implemented in enterprise network infrastructure to provide a redundant source of network communications. It serves as a backup mechanism for quickly swapping network operations onto redundant infrastructure in the event of unplanned network outages.
Typically, network redundancy is achieved through the addition of alternate network paths, which are implemented through redundant standby routers and switches. When the primary path is unavailable, the alternate path can be instantly deployed to ensure minimal downtime and continuity of network services.
IEEE 802.1Q is the networking standard that supports virtual LANs (VLANs) on an Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames. The standard also contains provisions for a quality of service prioritization scheme commonly known as IEEE 802.1p and defines the Generic Attribute Registration Protocol.
Portions of the network which are VLAN-aware (i.e., IEEE 802.1Q conformant) can include VLAN tags. When a frame enters the VLAN-aware portion of the network, a tag is added to represent the VLAN membership of the frame’s port or the port/protocol combination, depending on whether port-based or port-and-protocol-based VLAN classification is being used.
Each frame must be distinguishable as being within exactly one VLAN. A frame in the VLAN-aware portion of the network that does not contain a VLAN tag is assumed to be flowing on the native (or default) VLAN.
ACCEPT – SCHEME
Router has a f0/0 and serial interface, and these different interfaces must be on different networks
Switch 1 and switch 2 are connected, and therefore both groups are on the same network
