D.

active

D.

active

Answers
Suggested answer: D

Explanation:

From the neighbor status, we notice the "Flags" are SP. "P" here means the neighbor is in Passive mode.

In order to create an Etherchannel interface, the (local) SW1 ports should be in Active mode.

Moreover, the "Port State" in the exhibit is "0x3c" (which equals to "00111100 in binary format).

Bit 3 is "1" which means the ports are synchronizing -> the ports are working so the local ports should be in Active mode.

Which result occurs when PortFast is enabled on an interface that is connected to another switch?

After spanning tree converges PortFast shuts down any port that receives BPDUs.

D.

After spanning tree converges PortFast shuts down any port that receives BPDUs.

Answers
Suggested answer: A

Explanation:

Enabling the PortFast feature causes a switch or a trunk port to enter the STP forwarding-state immediately or upon a linkup event, thus bypassing the listening and learning states.

Note: To enable portfast on a trunk port you need the trunk keyword "spanning-tree portfast trunk

What is the primary different between AAA authentication and authorization?

Answers
Suggested answer: C

Explanation:

AAA stands for Authentication, Authorization and Accounting.

+ Authentication: Specify who you are (usually via login username & password) + Authorization: Specify what actions you can do, what resource you can access + Accounting: Monitor what you do, how long you do it (can be used for billing and auditing) An example of AAA is shown below:

+ Authentication: "I am a normal user. My username/password is user_tom/learnforever" + Authorization: "user_tom can access LearnCCNA server via HTTP and FTP" + Accounting: "user_tom accessed LearnCCNA server for 2 hours".

This user only uses "show" commands.

D.

as-path

Answers
Suggested answer: C

Explanation:

If a router learns two different paths for the same network from the same routing protocol, it has to decide which route is better and will be placed in the routing table. Metric is the measure used to decide which route is better (lower number is better). Each routing protocol uses its own metric.

For example, RIP uses hop counts as a metric, while OSPF uses cost.
