200-105 practice test

1. Question 1 · 1

   Which Cisco platform can verify ACLs?

   Choose one answer.

   • Cisco Prime Infrastructure
   • Cisco Wireless LAN Controller
   • Cisco APIC-EM
   • Cisco IOS-XE

2. Question 2 · 1

   Which encapsulation type is a Frame Relay encapsulation type that is supported by Cisco routers?

   Choose one answer.

   • IETF
   • ANSI Annex D
   • Q9333-A Annex A
   • HDLC

   Read explanation

   Cisco supports two Frame Relay encapsulation types: the Cisco encapsulation and the IETF Frame Relay encapsulation, which is in conformance with RFC 1490 and RFC 2427. The former is often used to connect two Cisco routers while the latter is used to connect a Cisco router to a non-Cisco router. You can test with your Cisco router when typing the command Router(config-if)#encapsulation frame-relay? on a WAN link. Note: Three LMI options are supported by Cisco routers are ansi, Cisco, and Q933a. They represent the ANSI Annex D, Cisco, and ITU Q933-A (Annex A) LMI types, respectively. HDLC is a WAN protocol same as Frame-Relay and PPP so it is not a Frame Relay encapsulation type.

3. Question 3 · 1

   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.)

   Choose all answers that apply.

   • Corp-1
   • Corp-2
   • Corp-3
   • Corp-4
   • Branch-1
   • Branch-2

   Read explanation

   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) & Branch-2 (10.2.20.20) have highest "active" IP addresses so they will become DRs.

4. Question 4 · 1

   Which statement about QoS default behavior is true?

   Choose one answer.

   • Ports are untrusted by default.
   • VoIP traffic is passed without being tagged.
   • Video traffic is passed with a well-known DSCP value of 46.
   • Packets are classified internally with an environment.
   • Packets that arrive with a tag are untagged at the edge of an administrative domain.

5. Question 5 · 1

   Refer to the exhibit. Router edge-1 is unable to establish OSPF neighbor adjacency with router ISP-1. Which two configuration changes can you make on edge-1 to allow the two routers to establish adjacency? (Choose two.)

   Choose all answers that apply.

   

   • Set the subnet mask on edge-1 to 255.255.255.252.
   • Reduce the MTU on edge-1 to 1514.
   • Set the OSPF cost on edge-1 to 1522.
   • Reduce the MTU on edge-1 to 1500.
   • Configure the ip ospf mtu-ignore command on the edge-1 Gi0/0 interface.

6. Question 6 · 1

   R1 is configured with the default configuration of OSPF. From the following list of IP addresses configured on R1, which address will the OSPF process select as the router ID?

   Choose one answer.

   

   

   • 192.168.0.1
   • 172.16.1.1
   • 172.16.2.1
   • 172.16.2.225

   Read explanation

   The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence: + 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. + The router ID can be manually assigned In this case, because a loopback interface is not configured so the highest active IP address 192.168.0.1 is chosen as the router ID.

7. Question 7 · 1

   Which statement about named ACLs is true?

   Choose one answer.

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

8. Question 8 · 1

   A department decides to replace its hub with a Catalyst 2950 switch that is no longer needed by another department.

However, PCs that are connected to the switch experience various connectivity problems. What is a possible cause of the problem?

   Choose one answer.

   • The VLAN database was not erased.
   • The management VLAN is disabled.
   • The running configuration should have been erased.
   • The "mode" button was not pressed when the switch was reloaded.
