RSTP expands the STP port roles by adding the alternate and backup roles.
B -
RSTP significantly reduces topology reconverging time after a link failure.
C -
RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.

3-
Which statement is true, as relates to classful or classless routing?
A -
Automatic summarization at classful boundaries can cause problems on discontinuous subnets.
B -

Statements A, B, C, and D of ACL 10 have been entered in the shown order and applied to
interface E0inbound, to prevent all hosts (except those whose address are the first and last IP of
subnet 172.21.1.128/28) from accessing the network. But as is, the ACL does not restrict anyone
from the network. How can the ACL statements be re-arranged so that the system works as
intended?
A -
CDBA
B -
ACDB
C -
BADC
D -
DBAC

B -
Gateway_Router is configured to only receive RIPv2 updates.
C -
Branch_Router2 is configured to send both RIPv1 and RIPv2 updates.
D -
Branch_Router1 is configured to only send RIPv1 updates.

B -
10.0.0.0/30 is subnetted, 1 subnets D 10.4.4.4 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
C -
10.0.0.0/28 is subnetted, 1 subnets D 10.4.4.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
D -
10.0.0.0/28 is subnetted, 1 subnets D 10 2 0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1

8-
A network administrator needs to configure port security on a switch. Which one statements is
true?
A -
The network administrator can apply port security to dynamic access points.
B -
When dynamic MAC address learning is enabled on an interface, the switch can learn new addresses, up to the maximum defined.
C -
The network administrator can configure static secure or sticky secure MAC addresses in the voice VLAN.
D -
The network administrator can apply port security to EtherChannels.
9-
Which one statements accurately describe Layer 2 Ethernet switches?
A -
Microsegmentation decreases the number of collisions on the network.
B -
In a properly functioning network with redundant switched paths, each switched segment will contain one root bridge with all its ports in the forwarding state. All other switches in that broadcast domain will have only one root port.
C -
Establishing vlans increases the number of broadcast domains.
