Cisco 200-105 Online Questions & Answers

• Question 171:

  What occurs on a Frame Relay network when the CIR is exceeded?

  A. All TCP traffic is marked discard eligible.
  B. All UDP traffic is marked discard eligible and a BECN is sent.
  C. All TCP traffic is marked discard eligible and a BECN is sent.
  D. All traffic exceeding the CIR is marked discard eligible.
  D. All traffic exceeding the CIR is marked discard eligible.

  ---

  Committed information rate (CIR): The minimum guaranteed data transfer rate agreed to by the Frame Relay switch. Frames that are sent in excess of the CIR are marked as discard eligible (DE) which means they can be dropped if the

  congestion occurs within the Frame Relay network.

  Note: In the Frame Relay frame format, there is a bit called Discard eligible (DE) bit that is used to identify frames that are first to be dropped when the CIR is exceeded.

• Question 172:

  Which feature must you enable to distribute vlans automatically across multiple switch?

  A. Configure NTP
  B. Configure the native VLAN
  C. Define Each vlan
  D. Configure VTP
  D. Configure VTP

• Question 173:

  What OSPF command, when configured, will include all interfaces into area 0?

  A. network 0.0.0.0 255.255.255.255 area 0
  B. network 0.0.0.0 0.0.0.0 area 0
  C. network 255.255.255.255 0.0.0.0 area 0
  D. network all-interfaces area 0
  A. network 0.0.0.0 255.255.255.255 area 0

  ---

  Example 3-1 displays OSPF with a process ID of 1 and places all interfaces configured with an IP address in area 0. The network command network 0.0.0.0 255.255.255.255 area 0 dictates that you do not care what the IP address is, but if an IP address is enabled on any interface, place it in area 0. Example 3-1 Configuring OSPF in a Single Area router ospf 1 network 0.0.0.0 255.255.255.255 area 0

• Question 174:

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

  Follow these guidelines when configuring port security:

  Port security can only be configured on static access ports, trunk ports, or 802.1Q tunnel ports.

  A secure port cannot be a dynamic access port.

  A secure port cannot be a destination portfor Switched Port Analyzer (SPAN).

  A secure port cannot belong to a Fast EtherChannel or Gigabit EtherChannel port group.

  You cannot configure static secure or sticky secure MAC addresses on a voice VLAN.

  When you enable port security on an interface that is also configured with a voice VLAN, you must set the maximum allowed secure addresses on the port to at least two.

  If any type of port security is enabled on the access VLAN, dynamic port security is automatically enabled on the voice VLAN.

  When a voice VLAN is configured on a secure port that is also configured as a sticky secure port, all addresses seen on the voice VLAN are learned as dynamic secure addresses, and all addresses seen on the access VLAN (to which the

  port belongs) are learned as sticky secure addresses.

  The switch does not support port security aging of sticky secure MAC addresses.

  The protect and restrict options cannot be simultaneously enabled on an interface

• Question 175:

  What are three features of the IPv6 protocol? (Choose three.)

  A. optional IPsec
  B. autoconfiguration
  C. no broadcasts
  D. complicated header
  E. plug-and-play
  F. checksums
  B. autoconfiguration
  C. no broadcasts
  E. plug-and-play

• Question 176:

  The internetwork infrastructure of company XYZ consists of a single OSPF area as shown in the graphic. There is concern that a lack of router resources is impeding internetwork performance. As part of examining the router resources, the OSPF DRs need to be known. All the router OSPF priorities are at the default and the router IDs are shown with each router.

  Which routers are likely to have been elected as DR? (Choose two.)

  

  A. Corp-1
  B. Corp-2
  C. Corp-3
  D. Corp-4
  E. Branch-1
  F. Branch-2
  D. Corp-4
  F. Branch-2

  ---

  There are 2 segments on the topology above which are separated by Corp-3 router.

  Each segment will have a DR so we have 2 DRs.

  To select which router will become DR they will compare their router-IDs. The router with highest (best) router-ID will become DR. The router-ID is chosen in the order below:

  The highest IP address assigned to a loopback (logical) interface.

  If a loopback interface is not defined, the highest IP address of all active router's physical interfaces will be chosen.

  In this question, the IP addresses of loopback interfaces are not mentioned so we will consider IP addresses of all active router's physical interfaces. Router Corp-4 (10.1.40.40) and Branch-2 (10.2.20.20) have highest "active" IP addresses so

  they will become DRs.

• Question 177:

  What is the default value of the Read-Write-All-SNMP community string?

  A. Secret
  B. Private
  C. Public
  D. Cisco
  A. Secret

  ---

  On Catalyst switches such as the 4000, 5000, and 6000 series that run a regular catalyst Operating System (OS), SNMP is enabled by default with the community strings set to: Read-Only: Public Read-Write: Private Read-Write-all: Secret

• Question 178:

  Which statement describes VRRP object tracking?

  A. It monitors traffic flow and link utilization.
  B. It ensures the best VRRP router is the virtual router master for the group.
  C. It causes traffic to dynamically move to higher bandwidth links.
  D. It thwarts man-in-the-middle attacks.
  B. It ensures the best VRRP router is the virtual router master for the group.

  ---

  VRRP object tracking provides a way to ensure the best VRRP router is virtual router master for the group by altering VRRP priorities to the status of tracked objects such as interface or IP route states.
