Creating a User Template in Active Directory
May 21st
When you are creating several users with similar account options and group membership creating those users would be a repetitive and time consuming task. However, in Active Directory you may be able to reduce some of the repetition by creating a USER TEMPLATE.
User template simply an inactive user account (disabled account) that can be copied to create users with common attributes. Copying from the User Template Account will run the same wizard for creating a new user account so you can fill in the missing fields such as username and password, as well as you can make some changes on those in common attributes fields.

CCNA Exploration2: Routing Protocols and Concepts – Final Exam
May 6th
01. 
Refer to the exhibit.
R1 knows two routes, Path A and Path B, to the Ethernet network attached to R3. R1 learned Path A to network 10.2.0.0/16 from a static route and Path B to network 10.2.0.0/16 from EIGRP. Which route will R1 install in its routing table?
- Both routes are installed and load balancing occurs across both paths.
- The route via Path B is installed because the EIGRP route has the best metric to network 10.2.0.0/16.
- The route via Path A is installed because the static route has the best metric to network 10.2.0.0/16.
- The route via Path B is installed because the EIGRP route has the lowest administrative distance to network 10.2.0.0/16.
- The route via Path A is installed because the static route has the lowest administrative distance to network 10.2.0.0/16. Read the rest of this entry »

01. 
Refer to the exhibit. What can be determined from this output?
- The router will have to perform recursive lookups to forward a packet destined for 192.168.2.213/24.
- The parent route for these networks was removed from the routing table.
- A route to 192.168.0.0/25 would be classified as a supernet route for the routes listed in the routing table.
- All of the routes listed are network routes.
02. 
Refer to the exhibit. A packet destined for host 128.107.0.5/16 is processed by the JAX router. After finding the static route in the routing table that matches the destination network for this packet, what does the router do next?
- searches for a default route to forward the packet
- drops the packet since the static route does not have an exit interface
- performs a recursive lookup to find the exit interface used to forward the packet
- sends a request to neighboring routers for the location of the 128.107.0.0 network Read the rest of this entry »
