• Question 934:

  In order to comply with new auditing standards, a security administrator must be able to correlate system security alert logs directly with the employee who triggers the alert. Which of the following should the security administrator implement in order to meet this requirement?

  A. Access control lists on file servers
  B. Elimination of shared accounts
  C. Group-based privileges for accounts
  D. Periodic user account access reviews
  D. Periodic user account access reviews

• Question 935:

  What is one benefit of PVST+?

  A. PVST+ supports Layer 3 load balancing without loops.
  B. PVST+ reduces the CPU cycles for all the switches in the network.
  C. PVST+ allows the root switch location to be optimized per VLAN.
  D. PVST+ automatically selects the root bridge location, to provide optimized bandwidth usage.
  C. PVST+ allows the root switch location to be optimized per VLAN.

  ---

  The PVST+ provides Layer 2 load-balancing for the VLAN on which it runs. You can create different logical topologies by using the VLANs on your network to ensure that all of your links are used but that no one link is oversubscribed. Each

  instance of PVST+ on a VLAN has a single root switch. This root switch propagates the spanning-tree information associated with that VLAN to all other switches in the network. Because each switch has the same information about the

  network, this process ensures that the network topology is maintained and optimized per VLAN.

• Question 936:

  which two statements about MPLS are true ?

  A. it encapsulates all traffic in an ipv4 header
  B. it provides automatic authentication
  C. it uses labels to separate and forward customer traffic
  D. it can carry multiple protocols, including ipv4 and ipv6
  E. it tags customer traffic using 802.1q
  C. it uses labels to separate and forward customer traffic
  D. it can carry multiple protocols, including ipv4 and ipv6

• Question 937:

  What are two requirements for an HSRP group? (Choose two.)

  A. exactly one active router
  B. one or more standby routers
  C. one or more backup virtual routers
  D. exactly one standby active router
  E. exactly one backup virtual router
  A. exactly one active router

• Question 938:

  At which layer of the OSI model is RSTP used to prevent loops?

  A. physical
  B. data link
  C. network
  D. transport
  B. data link

  ---

  RSTP and STP operate on switches and are based on the exchange of Bridge Protocol Data Units (BPDUs) between switches. One of the most important fields in BPDUs is the Bridge Priority in which the MAC address is used to elect the Root Bridge -> RSTP operates at Layer 2 ?Data Link layer >;.

• Question 939:

  -You notice that packets that are sent from a local host to well-known service on TCP port 80 remote host are sometimes lost. You suspect an ACL issue. Which two APIC-EM path Trace ACL-analysis option should you use to troubleshooting the problem? (Choose two.)

  A. destination port
  B. QoS
  C. debug
  D. protocol
  E. performance Monitor
  A. destination port
  C. debug

• Question 940:

  Which function allows EIGRP peers to receive notice of implementing topology changes?

  A. successors
  B. advertised changes
  C. goodbye messages
  D. expiration of the hold timer
  C. goodbye messages
