• Question 351:

  Which VLAN bridge priority value will make a switch as root for a given VLAN from the below options by the spanning-tree vlan vlan-id root command?

  A. 16384
  B. 8192
  C. 28672
  D. 32768
  B. 8192

• Question 352:

  You have been asked to come up with a subnet mask that will allow all three web servers to be on the same network while providing the maximum number of subnets. Which network address and subnet mask meet this requirement?

  A. 192.168.252.0 255.255.255.252
  B. 192.168.252.8 255.255.255.248
  C. 192.168.252.8 255.255.255.252
  D. 192.168.252.16 255.255.255.240
  E. 192.168.252.16 255.255.255.252
  B. 192.168.252.8 255.255.255.248

  ---

  A subnet mask of 255.255.255.248 will allow for up to 6 hosts to reside in this network. A subnet mask of 255.255.255.252 will allow for only 2 usable IP addresses, since we cannot use the network or broadcast address.

  E. Configure a loopback interface.
  C. Enable PPPoE on the interface.
  E. Configure a loopback interface.

• Question 354:

  Which command sets and automatically encrypts the privileged enable mode password?

  A. Enable password c1sc0
  B. Secret enable c1sc0
  C. Password enable c1sc0
  D. Enable secret c1sc0
  D. Enable secret c1sc0

• Question 355:

  which two options are the best reasons to use an ipv4 private ip space ?

  A. to manage routing overhead
  B. to implement nat
  C. to connect applications
  D. to enable intra-enterprise communication
  E. to conserve global address space
  D. to enable intra-enterprise communication
  E. to conserve global address space

• Question 356:

  On which type of port can switches interconnect for multi-VLAN communication?

  A. interface port
  B. access port
  C. switch port
  D. trunk port
  D. trunk port

• Question 357:

  Which switch would STP choose to become the root bridge in the selection process?

  A. 32768: 11-22-33-44-55-66
  B. 32768: 22-33-44-55-66-77
  C. 32769: 11-22-33-44-55-65
  D. 32769: 22-33-44-55-66-78
  A. 32768: 11-22-33-44-55-66

  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.

• Question 358:

  D. channel-group 10 mode desirable
  E. channel-group 10 mode auto
  C. channel-group 10 mode active
  D. channel-group 10 mode desirable

• Question 359:

  Which two statements about UDP are true? (Choose two)

  A. It can transmit data at a rate higher than the path capacity
  B. It uses a three-way handshake to ensure that traffic is transmated properly
  C. It guarantees packet delivery
  D. it includes protection against duplicate packets
  E. it can be used for multicast and broadcast traffic
  A. It can transmit data at a rate higher than the path capacity
  E. it can be used for multicast and broadcast traffic
