Question 1

Which protocol is used for port-level access control and authentication?

Accepted Answer

802.1X is the protocol used for port-level access control and authentication. It provides an authentication framework for secure and controlled access to network devices. MD5 and AES are encryption algorithms, while IPsec is a protocol used for secure communication over the internet.

Question 10

Which type of BGP is used to peer with a different autonomous system?

Accepted Answer

External BGP (eBGP) is used to peer with a different autonomous system (AS). eBGP is used between routers in different ASs to exchange network reachability information, which enables the routers to forward traffic between different ASs. This is in contrast to Internal BGP (iBGP), which is used to exchange routing information within the same AS. Classless, dynamic, and static are not relevant to the type of BGP used to peer with a different AS.

Question 16

You are implementing a single spanning tree instance in your network and want to use the protocol that will give you the best convergence time in the event of a physical network failure of the root bridge. Which spanning tree protocol will satisfy this requirement?

Accepted Answer

RSTP (Rapid Spanning Tree Protocol) provides faster convergence time compared to STP (Spanning Tree Protocol) and MSTP (Multiple Spanning Tree Protocol). RSTP achieves this by immediately transitioning ports to forwarding state instead of waiting for the usual listening and learning states in STP. VSTP (Vendor-Specific Spanning Tree Protocol) is a Cisco proprietary protocol that supports MSTP and RSTP.

Question 20

Your company has expanded into office space across the street. The new office space has a single Ethernet connection connected to an unmanaged switch. You must sort traffic based on the IP address into different VLANs once the traffic arrives on your EX Series switches. Which mechanism would you use to accomplish this task?

Accepted Answer

Filter-based VLANs allow you to sort traffic based on criteria such as IP addresses, and assign them to specific VLANs. This can be accomplished by setting up filters or rules that match specific traffic and then assigning it to a particular VLAN. MVRP, Q-in-Q tunneling, and Dynamic VLANs are other mechanisms for configuring VLANs on an EX Series switch, but they are not designed specifically for sorting traffic based on IP addresses.
