Cisco CCNA 200-301 Questions & Answers

• Question 721:

  Which two statements about exterior routing protocols are true? (Choose two.)

  A. They determine the optimal within an autonomous system.

  B. They determine the optimal path between autonomous systems.

  C. BGP is the current standard exterior routing protocol.

  D. Most modern networking supports both EGP and BGP for external routing.

  E. Most modern network routers support both EGP and EIGRP for external routing.

  Correct Answer: BC

  Exterior Gateway Protocols (EGP): Used for routing between autonomous systems. It is also referred to as inter-AS routing. Service providers and large companies may interconnect using an EGP. The Border Gateway Protocol (BGP) is the only currently viable EGP and is the official routing protocol used by the Internet. NOTE Because BGP is the only EGP available, the term EGP is rarely used; instead, most engineers simply refer to BGP. https://www.ciscopress.com/articles/article.asp?p=2180210andseqNum=7

• Question 722:

  Which statement about LLDP is true?

  A. It is a Cisco proprietary protocol.

  B. It is configured in global configuration mode.

  C. The LLDP update frequency is a fixed value.

  D. It runs over the transport layer.

  Correct Answer: B

  This answer is supported by search results [1], [2], [3], [4], [5], [6], [7], [8], and [9], which all state that LLDP is configured in global configuration mode . The other statements listed as choices are incorrect. LLDP is not a Cisco proprietary protocol (A) - it is a vendor-neutral protocol. The LLDP update frequency is not necessarily fixed (C) - it can be configured. LLDP runs over the data link layer, not the transport layer (D)

• Question 723:

  What criteria is used first during the root port selection process?

  A. local port ID

  B. lowest path cost to the toot bridge

  C. lowest neighbor's bridge ID

  D. lowest neighbor's port ID

  Correct Answer: B

• Question 724:

  Which statement about VLAN configuration is true?

  A. The switch must be in VTP server or transparent mode before you can configure a VLAN

  B. The switch must be in config-vlan mode before you configure an extended VLAN

  C. Dynamic inter-VLAN routing is supported on VLAN2 through VLAN 4064

  D. A switch in VTP transparent mode save the VLAN databases to the running configuration only

  Correct Answer: A

• Question 725:

  Which command must you enter to guarantee that an HSRP router with higher priority becomes the HSRP primary router after it is reloaded?

  A. standby 10 preempt

  B. standby 10 version 1

  C. standby 10 priority 150

  D. standby 10 version 2

  Correct Answer: A

  The "preempt" command enables the HSRP router with the highest priority to immediately become the active router.

• Question 726:

  Which command should you enter to verify the priority of a router in an HSRP group?

  A. show hsrp

  B. show sessions

  C. show interfaces

  D. show standby

  Correct Answer: D

  The following is sample output from the show standby command:

  

• Question 727:

  On a corporate network, hosts on the same VLAN can communicate with each other, but they are unable to communicate with hosts on different VLANs. What is needed to allow communication between the VLANs?

  A. a router with subinterfaces configured on the physical interface that is connected to the switch

  B. a router with an IP address on the physical interface connected to the switch

  C. a switch with an access link that is configured between the switches

  D. a switch with a trunk link that is configured between the switches

  Correct Answer: A

  Different VLANs can't communicate with each other, they can communicate with the help of Layer3 router. Hence, it is needed to connect a router to a switch, then make the sub-interface on the router to connect to the switch, establishing Trunking links to achieve communications of devices which belong to different VLANs.

• Question 728:

  What are two benefits of using VTP in a switching environment? (Choose two.)

  A. It allows switches to read frame tags.

  B. It allows ports to be assigned to VLANs automatically.

  C. It maintains VLAN consistency across a switched network.

  D. It allows frames from multiple VLANs to use a single interface.

  E. It allows VLAN information to be automatically propagated throughout the switching environment.

  Correct Answer: CE

• Question 729:

  Which three statements are typical characteristics of VLAN arrangements? (Choose three.)

  A. A new switch has no VLANs configured.

  B. Connectivity between VLANs requires a Layer 3 device.

  C. VLANs typically decrease the number of collision domains.

  D. Each VLAN uses a separate address space.

  E. A switch maintains a separate bridging table for each VLAN.

  F. VLANs cannot span multiple switches.

  Correct Answer: BDE

  To communicate between two different VLANs we need to use a Layer 3 device like router or Layer 3 switch -> B is correct.

  VLANs don't affect the number of collision domains, they are the same -> C is not correct. Typically, VLANs increase the number of broadcast domains.

  We must use a different network (or sub-network) for each VLAN. For example we can use 192.168.1.0/24 for VLAN 1, 192.168.2.0/24 for VLAN 2 -> D is correct.

  A switch maintains a separate bridging table for each VLAN so that it can send frame to ports on the same VLAN only. For example, if a PC in VLAN 2 sends a frame then the switch look-ups its bridging table and only sends frame out of its ports which belong to VLAN 2 (it also sends this frame on trunk ports) -> E is correct.

• Question 730:

  Which two commands can you use to configure an actively negotiate EtherChannel? (Choose two.)

  A. channel-group 10 mode on

  B. channel-group 10 mode auto

  C. channel-group 10 mode passive

  D. channel-group 10 mode desirable

  E. channel-group 10 mode active

  Correct Answer: DE

  Desirable mode: Desirable mode in Port Aggregation Protocol (PAgP) initiates the negotiation and tries to form EtherChannel with other end. Active Mode: Active Mode in Link Aggregation Control Protocol (LACP) initiates the negotiation and tries to form EtherChannel with other end.
