• Question 894:

  What is the difference between CEF and process switching?

  A. CEF processes packets that are too complex for process switching to manage.
  B. CEF is more CPU-intensive than process switching.
  C. CEF uses the FIB and the adjacency table to make forwarding decisions, whereas process switching punts each packet.
  D. Process switching is faster than CEF.
  C. CEF uses the FIB and the adjacency table to make forwarding decisions, whereas process switching punts each packet.

  Explanation

  "Punt" is often used to describe the action of moving a packet from the fast path (CEF) to the route processor for handling. Cisco Express Forwarding (CEF) provides the ability to switch packets through a device in a very quick and efficient way while also keeping the load on the router`s processor low. CEF is made up of two different main components: the Forwarding Information Base (FIB) and the Adjacency Table. Process switching is the slowest switching methods (compared to fast switching and Cisco Express Forwarding) because it must find a destination in the routing table. Process switching must also construct a new Layer 2 frame header for every packet. With process switching, when a packet comes in, the scheduler calls a process that examines the routing table, determines which interface the packet should be switched to and then switches the packet. The problem is, this happens for the every packet.

• Question 895:

  Which WLC discovery method uses Cisco CAPWAP controller as an identifier?

  A. static configuration
  B. DHCP
  C. L3 broadcast
  D. DNS
  D. DNS

• Question 896:

  An engineer must configure interface GigabitEthernet0/0 for VRRP group 10. When the router has the highest priority in the group, it must assume the master role. Which command set must be added to the initial configuration to accomplish this task?

  Initial Configuration

  interface GigabitEthernet0/0 description To IDF A 38-24-044.40 ip address 172.16.13.2 255.255.255.0

  A. vrrp 10 ip 172.16.13.254vrrp 10 preempt
  B. standby 10 ip 172.16.13.254standby 10 priority 120
  C. vrrp group 10 ip 172.16.13 254.255.255.255.0vrrp group 10 priority 120
  D. standby 10 ip 172.16.13.254 255.255.255.0standby 10 preempt
  A. vrrp 10 ip 172.16.13.254vrrp 10 preempt

  ---

  Explanation

  In fact, VRRP has the preemption enabled by default so we don`t need the vrrp 10 preempt command. The default priority is 100 so we don`t need to configure it either. But notice that the correct command to configure the virtual IP address for the group is vrrp 10 ip {ip-address} (not vrrp group 10 ip ...) and this command does not include a subnet mask.

• Question 897:

  An engineer must create a new SSID on a Cisco 9800 wireless LAN controller. The client has asked to use a pre-shared key for authentication Which profile must the engineer edit to achieve this requirement?

  A. RF
  B. Policy
  C. WLAN
  D. Flex
  C. WLAN

• Question 898:

  Which two actions are recommended as security best practice to protect REST API (Choose two)

  A. Use TACACACS+ authentication
  B. Enable dual authentication of the session
  C. Enable out-of band authentication
  D. Use SSL for encryption
  E. Use a password hash
  D. Use SSL for encryption
  E. Use a password hash

• Question 899:

  Which two parameters are examples of a QoS traffic descriptor? (Choose two)

  A. MPLS EXP bits
  B. bandwidth
  C. DSCP
  D. ToS
  E. packet size
  A. MPLS EXP bits
  C. DSCP

  ---

  Explanation

  From the OCG page 368:

  "The following traffic descriptors are typically used for classification:

  Internal: QoS groups (locally significant to a router) Layer 1: Physical interface, subinterface, or port Layer 2: MAC address and 802.1Q/p Class of Service (CoS) bits Layer 2.5: MPLS Experimental (EXP) bits Layer 3: Differentiated Services Code Points (DSCP), IP Precedence (IPP), and source/destination IP address Layer 4: TCP or UDP ports Layer 7: Next Generation Network-Based Application Recognition (NBAR2)".
