Demo Questions

Question 1

A network administrator needs to configure port security on a switch. Which two statements are true? (Choose two.)

  • A: The network administrator can apply port security to dynamic access ports.
  • B: The network administrator can apply port security to EtherChannels.
  • C: The sticky learning feature allows the addition of dynamically learned addresses to the running configuration.
  • D: When dynamic MAC address learning is enabled on an interface, the switch can learn new addresses, up to the maximum defined.
  • E: The network administrator can configure static secure or sticky secure MAC addresses in the voice VLAN.

Correct Answer: CD

Question 2

Which interface counter can you use to diagnose a duplex mismatch problem?

  • A: no carrier
  • B: late collisions
  • C: giants
  • D: CRC errors
  • E: deferred
  • F: runts

Correct Answer: B

Question 3

Which switching method duplicates the first six bytes of a frame before making a switching decision?

  • A: fragment-free switching
  • B: store-and-forward switching
  • C: cut-through switching
  • D: ASIC switching

Correct Answer: C

Question 4

Which logging command can enable administrators to correlate syslog messages with millisecond precision?

  • A: no logging console
  • B: logging buffered 4
  • C: no logging monitor
  • D: service timestamps log datetime mscec
  • E: logging host

Correct Answer: D

Question 5

Which two spanning-tree port states does RSTP combine to allow faster convergence? (Choose two.)

  • A: blocking
  • B: learning
  • C: forwarding
  • D: discarding
  • E: listening

Correct Answer: AE

Question 6

Which feature can you implement to reserve bandwidth for VoIP calls across the call path?

  • A: PQ
  • B: CBWFQ
  • C: round robin
  • D: RSVP

Correct Answer: D

Question 7

Which three statements about link-state routing are true? (Choose three.)

  • A: OSPF is a link-state protocol.
  • B: Updates are sent to a broadcast address.
  • C: It uses split horizon.
  • D: Routes are updated when a change in topology occurs.
  • E: RIP is a link-state protocol.
  • F: Updates are sent to a multicast address by default.

Correct Answer: ADF

Question 8

Which command can you enter to determine whether a switch is operating in trunking mode?

  • A: show ip interface brief
  • B: show vlan
  • C: show interfaces
  • D: show interface switchport

Correct Answer: D

Question 9

What are three benefits of implementing VLANs? (Choose three.)

  • A: A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
  • B: A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure.
  • C: A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.
  • D: Broadcast storms can be mitigated by decreasing the number of broadcast domains, thus increasing their size.
  • E: Port-based VLANs increase switch-port use efficiency, thanks to 802.1Q trunks.
  • F: VLANs make it easier for IT staff to configure new logical groups, because the VLANs all belong to the same broadcast domain.
  • G: Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size.

Correct Answer: ACG

Question 10

Which command can you enter to view the ports that are assigned to VLAN 20?

  • A: Switch#show ip interface vlan 20
  • B: Switch#show vlan id 20
  • C: Switch#show ip interface brief
  • D: Switch#show interface vlan 20

Correct Answer: B
