  2. Switch(config)#Interface gig x/y Switch(config-if)#vlan 20

    Switch(config-vlan)#switchport access vlan 20

  3. Switch(config)#vlan 20 Switch(config)#Interface vlan 20

    Switch(config-if)#switchport trunk native vlan 20

  4. Switch(config)#vlan 20 Switch(config)#Interface vlan 20 Switch(config-if)#switchport access vlan 20

  2. It goes into a down/down state.

  3. It becomes the root bridge for the configured VLAN.

  4. It goes into an errdisable state.

Answer: D

Dumps4Cert 2017 PDF and VCE

you determine that Computer A cannot ping Computer. Which reason for the problem is most likely true?

  1. The Subnet mask for Computer A is incorrect.

  2. The default gateway address for Computer A is incorrect.

  3. The subnet mask for computer B is incorrect.

  4. The default gateway address for computer B is incorrect.

Answer: A Explanation:

255.255.255.224 =/27

Question No: 335 – (Topic 8)

You enter the show ipv6 route command on an OSPF device and the device displays a route. Which conclusion can you draw about the environment?

  1. OSPF is distributing IPv6 routes to BGP.

  2. The router is designated as an ABR.

  3. The router is designated as totally stubby.

  4. OSPFv3 is in use.

Answer: A

Question No: 336 – (Topic 8)

Which value is used to determine the active router in an HSRP default configuration ?

  1. router tracking number

  2. router IP address

  3. router priority

  4. router loopback address

Answer: C

Question No: 337 – (Topic 8)

when you troubleshoot an IPv4 connectivity issue on a router, which three router configuration checks you must perform?

  1. Verify that the router interface IP address IP address is correct.

  2. Verify that the DNS is configured correctly.

  3. Verify that the router and the host use the same subnet mask.

  4. Verify that the router firmware is up-to-date.

  5. Verify that a default route is configured.

  6. Verify that the route appears in the routing table

Answer: A,B,F

Question No: 338 – (Topic 8)

Which option describes how a switch in rapid PVST mode responds to a topology change?

  1. It immediately deletes dynamic MAC addresses that were learned by all ports on the switch.

  2. It sets a timer to delete all MAC addresses that were learned dynamically by ports in the same STP instance.

  3. It sets a timer to delete dynamic MAC addresses that were learned by all ports on the switch.

  4. It immediately deletes all MAC addresses that were learned dynamically by ports in the same STP instance.

Answer: D Explanation:

Rapid PVST This spanning-tree mode is the same as PVST except that is uses a rapid convergence based on the IEEE 802.1w standard. To provide rapid convergence, the rapid PVST immediately deletes dynamically learned MAC address entries on a per-port basis upon receiving a topology change. By contrast, PVST uses a short aging time for dynamically learned MAC address entries.

The rapid PVST uses the same configuration as PVST (except where noted), and the switch needs only minimal extra configuration. The benefit of rapid PVST is that you can migrate a large PVST install base to rapid PVST without having to learn the complexities of the MSTP configuration and without having to reprovision your network. In rapid-PVST mode, each VLAN runs its own spanning-tree instance up to the maximum supported.

Question No: 339 – (Topic 8)

When you enable PortFast on a switch port, the port immediately transitions to which state?

  1. learning

  2. blocking

  3. forwarding

  4. listening

Answer: C

Question No: 340 DRAG DROP – (Topic 8)

Drag each IPv6 prefix on the left to its use on the right.
