10 Tips For Most up-to-date 200-125 braindumps

Answer: B

Explanation:

In computing, traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop indicates the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated. Ping, on the other hand, only computes the final round-trip times from the destination point.

Answer: A

Explanation:

The root bridge of the spanning tree is the bridge with the smallest (lowest) bridge ID. Each bridge has a configurable priority number and a MAC Address; the bridge ID contains both numbers combined together - Bridge priority + MAC (32768.0200.0000.1111). The Bridge priority default is 32768 and can only be configured in multiples of 4096(Spanning tree uses the 12 bits extended system ID). To compare two bridge IDs, the priority is compared first, as if looking at a real number anything less than 32768...will become the target of being the root. If two bridges have equal priority then the MAC addresses are compared; for example, if switches A (MAC=0200.0000.1111) and B (MAC=0200.0000.2222) both have a priority of 32768 then switch A will be selected as the root bridge.

In this case, 32768: 11-22-33-44-55-66 would be the bridge because it has a lower priority and MAC address.

Answer: B

Explanation:

310 hosts < 512 = 29-> We need a subnet mask of 9 bits 0 -> 1111 1111.1111 1111.1111

1110.0000 0000 -> 255.255.254.0

Answer: C

Explanation:

EIGRP uses the Neighbor Table to list adjacent routers. The Topology Table list all the learned routers to destination whilst the Routing Table contains the best route to a destination, which is known as the Successor. The Feasible Successor is a backup route to a destination which is kept in the Topology Table.

Answer: B,C,D

Explanation:

These are the different types of trunk modes:

u2711 ON: This mode puts the port into permanent trunk mode and negotiates to convert the link into a trunk link. The port becomes a trunk port even if the adjacent port does not agree to the change.

u2711 OFF: This mode puts the port into permanent non-trunk mode and negotiates to convert the link into a non-trunk link. The port becomes a non-trunk port even if the adjacent port does not agree to the change.

u2711 Desirable: This mode causes the port to actively attempt to convert the link into a

trunk link. The port becomes a trunk port if the adjacent port is set to on, desirable, or auto mode.

u2711 Auto: This mode enables the port to convert the link into a trunk link. The port

becomes a trunk port if the adjacent port is set to on or desirable mode. This is the default mode for Fast and Gigabit Ethernet ports.

u2711 Nonegotiate: This mode puts the port into permanent trunk mode, but does not

allow the port to generate Dynamic Trunking Protocol (DTP) frames. The adjacent port must be configured manually as a trunk port to establish a trunk link.

Answer: A,C,E

Explanation:

From the output, we learn that the IP address of the neighbor router is 10.1.1.2 and the question stated that the subnet mask of the network between two routers is 255.255.255.252. Therefore there are only 2 available hosts in this network (22 u2013 2 = 2). So we can deduce the ip address (of the serial interface) of Manchester router is 10.1.1.1 ->. The platform of the neighbor router is cisco 2610, as shown in the output ->.

Maybe the most difficult choice of this question is the answer E or F. Please notice that u201cInterfaceu201d refers to the local port on the local router, in this case it is the port of Manchester router, and u201cPort ID (outgoing port)u201d refers to the port on the neighbor router.

Answer: B,E

Explanation:

When network topology changes, rapid spanning tree protocol (IEEE802.1W, referred to as RSTP) will speed up significantly the speed to re-calculate spanning tree. RSTP not only defines the role of other ports: alternative port and backup port, but also defines status of 3 ports: discarding status, learning status, forwarding status.

RSTP is 802.1D standard evolution, not revolution. It retains most of the parameters, and makes no changes.

Answer: A

Explanation:

Router A receives 3 subnets: 172.16.64.0/18, 172.16.32.0/24 and 172.16.128.0/18.

All these 3 subnets have the same form of 172.16.x.x so our summarized subnet must be also in that form -> Only A, B or .

The smallest subnet mask of these 3 subnets is /18 so our summarized subnet must also have its subnet mask equal or smaller than /18.

-> Only answer A has these 2 conditions ->.

Answer: B

Explanation:

Configuring the Native VLAN for Untagged Traffic

A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic. By default, the switch forwards untagged traffic in the native VLAN configured for the port. The native VLAN is VLAN 1 by default.

Answer: D

Explanation:

There are two ways that an IPv6 address can be additionally compressed: compressing leading zeros and substituting a group of consecutive zeros with a single double colon (::). Both of these can be used in any number of combinations to notate the same address. It is important to note that the double colon (::) can only be used once within a single IPv6 address notation. So, the extra 0u2021s can only be compressed once.
