• Question 341:

  Which adverse circumstance can occur when you connect when you connect full-duplex devices to a shared Ethernet hub?

  A. excessive collisions
  B. alignment errors
  C. a duplex mismatch
  D. native VLAN mismatches
  A. excessive collisions

• Question 342:

  Refer to the exhibit.

  

  A problem with network connectivity has been observed. It is suspected that the cable connected to switch port Fa0/9 on Switch1 is disconnected. What would be an effect of this cable being disconnected?

  A. Host B would not be able to access the server in VLAN9 until the cable is reconnected.
  B. Communication between VLAN3 and the other VLANs would be disabled.
  C. The transfer of files from Host B to the server in VLAN9 would be significantly slower.
  D. For less than a minute, Host B would not be able to access the server in VLAN9. Then normal network function would resume.
  D. For less than a minute, Host B would not be able to access the server in VLAN9. Then normal network function would resume.

  Spanning-Tree Protocol (STP) is a Layer 2 protocol that utilizes a special-purpose algorithm to discover physical loops in a network and effect a logical loop-free topology. STP creates a loop-free tree structure consisting of leaves and branches that span the entire Layer 2 network. The actual mechanics of how bridges communicate and how the STP algorithm works will be discussed at length in the following topics. Note that the terms bridge and switch are used interchangeably when discussing STP. In addition, unless otherwise indicated, connections between switches are assumed to be trunks.

• Question 343:

  Which two statements about 1000BASE-T UTP cable are true? (Choose two)

  A. It uses four wires
  B. It uses four wire pairs
  C. It is most appropriate for installations up to 1000 feet in length
  D. It is most appropriate for installations up to 1000 meters in length
  E. Both ends of the cable can transmit and receive simultaneously
  B. It uses four wire pairs
  E. Both ends of the cable can transmit and receive simultaneously

• Question 344:

  Drag and Drop.

  Drag each definition on the left to the matching term on the right.

  Select and Place:

  

  

• Question 345:

  Which feature can validate address requests and filter out invalid messages?

  A. IP Source Guard
  B. port security
  C. DHCP snooping
  D. dynamic ARP inspection
  C. DHCP snooping

• Question 346:

  Which option describes the purpose of traffic policing?

  A. It prioritizes routing protocol traffic.
  B. It remarks traffic that is below the CIR
  C. It drops traffic that exceeds the CIR.
  D. It queues and then transmits traffic that exceeds the CIR.
  C. It drops traffic that exceeds the CIR.

  ---

  Traffic policing allows you to control the maximum rate of traffic transmitted or received on an interface. Traffic policing is often configured on interfaces at the edge of a network to limit traffic into or out of the network. In most Traffic Policing configurations, traffic that falls within the rate parameters is transmitted, whereas traffic that exceeds the parameters is dropped or transmitted with a different priority.

• Question 347:

  Refer to the exhibit.

  

  An attempt to deny web access to a subnet blocks all traffic from the subnet. Which interface command immediately removes the effect of ACL 102?

  A. no ip access-class 102 in
  B. no ip access-class 102 out
  C. no ip access-group 102 in
  D. no ip access-group 102 out
  E. no ip access-list 102 in
  D. no ip access-group 102 out

  ---

  The "ip access-group" is used to apply and ACL to an interface. From the output shown, we know that the ACL is applied to outbound traffic, so "no ip access-group 102 out" will remove the effect of this ACL.

• Question 348:

  Which parameter would you tune to affect the selection of a static route as a backup, when a dynamic protocol is also being used?

  A. hop count
  B. administrative distance
  C. link bandwidth
  D. link delay
  E. link cost
  B. administrative distance

  ---

  By default the administrative distance of a static route is 1, meaning it will be preferred over all dynamic routing protocols. If you want to have the dynamic routing protocol used and have the static route be used only as a backup, you need to increase the AD of the static route so that it is higher than the dynamic routing protocol.

• Question 349:

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

  A. PQ
  B. CBWFQ
  C. round robin
  D. RSVP
  D. RSVP

• Question 350:

  Which statement about DHCP address pools is true?

  A. A network must be defined before you can configure a manual binding.
  B. Only one DNSserver can be identified for an individual DHCP group.
  C. You can use a subnet mask of prefix length to define a network.
  D. The domain name of the DHCP pool is specified in the global configuration of the router.
  C. You can use a subnet mask of prefix length to define a network.
