Chapter 1 – Implement VLAN based solution, given a network design and a set of requirements

QUESTION NO: 31
What action should a network administrator take to enable VTP pruning on an entire management domain?
A. Enable VTP pruning on any client switch in the management domain.
B. Enable VTP pruning on any switch in the management domain.
C. Enable VTP pruning on every switch in the management domain.
D. Enable VTP pruning on a VTP server in the management domain.
E. Disable VTP pruning on a VTP server in the management domain.
Answer: D
Explanation:
Enabling VTP pruning on a VTP server allows pruning for the entire management domain. Enabling this on the VTP server will mean that the VTP pruning configuration will be propagated to all VTP client switches within the domain. VTP pruning takes effect several seconds after you enable it. By default, VLANs 2 through 1000 are pruning-eligible.

Chapter 1 – Implement VLAN based solution, given a network design and a set of requirements

QUESTION NO: 26
Switch R1 and R2 both belong to the Company VTP domain. What’s true about the switch operation in VTP domains? (Select all that apply)
A. A switch can only reside in one management domain
B. A switch is listening to VTP advertisements from their own domain only
C. A switch is listening to VTP advertisements from multi domains
D. A switch can reside in one or more domains
E. VTP is no longer supported on Catalyst switches
Answer: A,B
Explanation:
A VTP domain is made up of one or more interconnected devices that share the same VTP domain name. A switch can be configured to be in only one VTP domain, and each VLAN has a name that is unique within a management domain. Typically, you use a VTP domain to ease administrative control of your network or to account for physical boundaries within your network. However, you can set up as many or as few VTP domains as are appropriate for your administrative needs. Consider that VTP is transmitted on all trunk connections, including ISL, IEEE 802.1Q, 802.10, and LANE. Switches can only belong to one management domain with common VLAN requirements, and they only care about the neighbors in their own domains.

Chapter 1 – Implement VLAN based solution, given a network design and a set of requirements

QUESTION NO: 16
Static VLANs are being used on the Company network. What is true about static VLANs?
A. Devices use DHCP to request their VLAN.
B. Attached devices are unaware of any VLANs.
C. Devices are assigned to VLANs based on their MAC addresses.
D. Devices are in the same VLAN regardless of which port they attach to.
Answer: B
Explanation:
LAN port VLAN membership can be assigned manually on a port-by-port basis. When you assign LAN ports to VLANs using this method, it is known as port-based, or static, VLAN membership. Attached devices will be unaware of any VLANs.

QUESTION NO: 11
In the three-layer hierarchical network design model; what’s associated with the access layer? (Select two)
A. optimized transport structure
B. high port density
C. boundary definition
D. data encryption
E. local VLANs
F. route summaries
Answer: B,E
Explanation:
The access layer is the outermost layer, and it is composed of the least sophisticated network equipment. The most important function of the access layer is high port density, since these devices connect the individual end users. The access layers are also where VLANs are implemented, since VLANs are assigned on a per-port basis.

QUESTION NO: 6
What are some virtues of implementing end-to-end VLANs? (Choose two)
A. End-to-end VLANs are easy to manage.
B. Users are grouped into VLANs independent of a physical location.
C. Each VLAN has a common set of security and resource requirements for all members.
D. Resources are restricted to a single location.
Answer: B,C
Explanation:
In an end-to-end VLAN, users are grouped into VLANs independent of physical location and dependent on group or job function. Each VLAN has a common set of security requirements for all members.

QUESTION NO: 1
Which method of Layer 3 switching uses a forwarding information base (FIB)?
A. Topology-based switching
B. Demand-based switching
C. Route caching
D. Flow-based switching
E. None of the other alternatives apply
Answer: A
Explanation:
The Layer 3 engine (essentially a router) maintains routing information, whether from static routes or dynamic routing protocols. Basically, the routing table is reformatted into an ordered list with the most specific route first, for each IP destination subnet in the table. The new format is called a Forwarding Information Base (FIB) and contains routing or forwarding information that the network prefix can reference. In other words, a route to 10.1.0.0/16 might be contained in the FIB, along with routes to 10.1.1.0/24 and 10.1.1.128/25, if those exist. Notice that these examples are increasingly more specific subnets. In the FIB, these would be ordered with the most specific, or longest match, first, followed by less specific subnets. When the switch receives a packet, it can easily examine the destination address and find the longest match entry in the FIB. The FIB also contains the next-hop address for each entry. When a longest match entry is found in the FIB, the Layer 3 next-hop address is found, too.
