1. Refer to the exhibit. Company ABC expanded its business and recently opened a new branch office in another country. IPv6 addresses have been used for the company network. The data servers Server1 and Server2 run applications which require end-to-end functionality, with unmodified packets that are forwarded from the source to the destination.

A network administrator is tasked with maintaining two remote locations in the same city. Both locations use the same service provider and have the same service plan for DSL service.

The West side has a high volume of POTS traffic.
The West side of town is downloading larger packets.
More clients share a connection to the DSLAM on the West side.

Using Google Public DNS
Configuring your network settings to use Google Public DNS
When you use Google Public DNS, you are changing your DNS "switchboard" operator from your ISP to Google Public DNS.In most cases, the IP addresses used by your ISP's domain name servers are automatically set by your ISP via the Dynamic Host Configuration Protocol (DHCP). To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according to operating system and version (Windows, Mac or Linux) or the device (computer, phone, or router). We give general procedures here that might not apply for your OS or device; please consult your vendor documentation for authoritative information.
Note: We recommend that only users who are proficient with configuring operating system settings make these changes.
Important: Before you start
Before you change your DNS settings to use Google Public DNS, be sure to write down the current server addresses or settings on a piece of paper. It is very important that you keep these numbers for backup purposes, in case you need to revert to them at any time.After changing your settings, if you encounter a problem and cannot connect to the Internet, please call our support numbers for troubleshooting instructions.
We also recommend that you download this page and print it, in the event that you encounter a problem and need to refer to these instructions.
Google Public DNS telephone support
- 877-590-4367 in the U.S.
- 770-200-1201 outside the U.S.
Google Public DNS IP addresses
The Google Public DNS IP addresses are as follows:- 8.8.8.8
- 8.8.4.4

3
Which statement is correct about STP architecture?
The switch with the highest priority will be assigned the lowest BID in the root election.
The first step in the spanning-tree election process is to determine the root port.
To select designated ports, the spanning-tree algorithm must determine the longest contiguous path from the root bridge.
