Cisco 200-105 Online Questions & Answers

• Question 341:

  Which HSRP Feature was new in HSRPv2?

  A. Virtual MAC Address
  B. Preemption
  C. Tracking
  D. VLAN Group Numbers that are greater than 255
  D. VLAN Group Numbers that are greater than 255

• Question 342:

  Which statement about named ACLs is true?

  A. They support standard and extended ACLs.
  B. They are used to filter usernames and passwords for Telnet and SSH.
  C. They are used to filter Layer 7 traffic.
  D. They support standard ACLs only.
  E. They are used to rate limit traffic destined to targeted networks.
  A. They support standard and extended ACLs.

  ---

  Named Access Control Lists (ACLs) allows standard and extended ACLs to be given names instead of numbers. Unlike in numbered Access Control Lists (ACLs), we can edit Named Access Control Lists. Another benefit of using named access configuration mode is that you can add new statements to the access list, and insert them wherever you like. With the legacy syntax, you must delete the entire access list before reapplying it using the updated rules.

• Question 343:

  Which statement about MPLS is true?

  A. It operates in Layer 1.
  B. It operates between Layer 2 and Layer 3.
  C. It operates in Layer 3.
  D. It operates in Layer 2.
  B. It operates between Layer 2 and Layer 3.

  ---

  MPLS belongs to the family of packet-switched networks. MPLS operates at a layer that is generally considered to lie between traditional definitions of OSI Layer 2 (data link layer) and Layer 3 (network layer), and thus is often referred to as a layer 2.5 protocol.

• Question 344:

  A network administrator needs to allow only one Telnet connection to a router. For anyone viewing the configuration and issuing the show run command, the password for Telnet access should be encrypted.

  Which set of commands will accomplish this task?

  A. service password-encryption access-list permit 192.168.1.0.0.0.0.255 line vty0 4 login password cisco access-class 1
  B. enable password secret line vty0 login password cisco
  C. service password-encryption line vty0 login password cisco
  D. service password-encryption line vty0 4 login password cisco
  C. service password-encryption line vty0 login password cisco

• Question 345:

  Which spanning-tree feature places a port immediately into a forwarding state?

  A. BPDU guard
  B. PortFast
  C. loop guard
  D. UDLD
  E. UplinkFast
  B. PortFast

  ---

  PortFast causes a switch or trunk port to enter the spanning tree forwarding state immediately, bypassing the listening and learning states. You can use PortFast on switch or trunk ports that are connected to a single workstation, switch, or server to allow those devices to connect to the network immediately, instead of waiting for the port to transition from the listening and learning states to the forwarding state.

• Question 346:

  In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?

  A. during high traffic periods
  B. after broken links are re-established
  C. when upper-layer protocols require high reliability
  D. in an improperly implemented redundant topology
  E. when a dual ring topology is in use
  D. in an improperly implemented redundant topology

• Question 347:

  Which WAN technology is secure and encrypted by default?

  A. VPN
  B. VSAT
  C. DSL
  D. MPLS
  A. VPN

• Question 348:

  You work as a network engineer for SASCOM Network Ltd company. On router HQ, a provider link has been enabled and you must configure an IPv6 default route on HQ and make sure that this route is advertised in IPv6 OSPF process. Also, you must troubleshoot another issue. The router HQ is not forming an IPv6 OSPF neighbor relationship with router BR.

  Topology Details

  Two routers HQ and BR are connected via serial links.

  Router HQ has interface Ethernet0/1 connected to the provider cloud and interface Ethernet 0/0 connected to RA1

  Router BR has interface Ethernet 0/0 connected to another router RA2.

  IPv6 Routing Details

  Ail routers are running IPv6 OSPF routing with process ID number 100 Refer to the topology diagram for information about the OSPF areas The Loopback 0 IPv4 address is the OSPF router ID on each router

  Configuration requirements

  -

  Configure IPv6 default route on router HQ with default gateway as 2001:DB8:B:B1B2::1.

  -

  Verify by pinging provider test IPv6 address 2001 :DB8:0:1111:1 after configuring default route on HQ.

  -

  Make sure that the default route is advertised in IPv6 OSPF on router HQ This default route should be advertised only when HQ has a default route in its routing table.

  -

  Router HQ is not forming IPv6 OSPF neighbor with BR. You must troubleshoot and resolve this issue Special Note: To gain the maximum number of points, you must complete the necessary configurations and fix IPv6 OSPF neighbor issue with router BR IPv6 OSPFv3 must be configured without using address families. Do not change the IPv6 OSPF process ID.

  

  Correct Answer. Check the answer below
  Check the answer below

  ---

  1.

  Configure default route on router HQ: ipv6 unicast-routing ipv6 route ::/0 2001:DB8:B:B1B2::1

  2.

  Advertise this route under ospfv3 Ipv6 router ospf 100 Default-information originate

  3.

  Fix adjacency problem if a area mismatches We need to enter in s1/0 Ipv6 ospf 100 area 0

• Question 349:

  A network administrator receives an error message while trying to configure the Ethernet interface of a router with IP address 10.24.24.24/29.

  Which statement explains the reason for this issue?

  A. VLSM-capable routing protocols must be enabled first on the router.
  B. This address is a network address.
  C. This address is a broadcast address.
  D. The Ethernet interface is faulty.
  B. This address is a network address.

• Question 350:

  Refer to the exhibit.

  When running EIGRP, what is required for RouterA to exchange routing updates with RouterC?

  

  A. AS numbers must be changed to match on all the routers
  B. Loopback interfaces must be configured so a DR is elected
  C. The no auto-summary command is needed on Router A and Router C
  D. Router B needs to have two network statements, one for each connected network
  A. AS numbers must be changed to match on all the routers

  ---

  Here we required same autonomous system between router A,B,C.Routing updated always exchange between in same EIGRP EIGRP autonomous system. You can configure more than one EIGRP autonomous system on the same router. This is typically done at a redistribution point where two EIGRP autonomous systems are interconnected. Individual router interfaces should only be included within a single EIGRP autonomous system. Cisco does not recommend running multiple EIGRP autonomous systems on the same set of interfaces on the router. If multiple EIGRP autonomous systems are used with multiple points of mutual redistribution, it can cause discrepancies in the EIGRP topology table if correct filtering is not performed at the redistribution points. If possible, Cisco recommends you configure only one EIGRP autonomous system in any single autonomous system.
