Cisco 300-320 Online Questions & Answers

• Question 601:

  What are two advantages of using Cisco FEX devices in the data center design? (Choose two.)

  A. Traffic-forwarding decisions are made by the Cisco FEX device.
  B. Cisco FEX devices must be upgraded when the parent switch is upgraded.
  C. Traffic-forwarding decisions are made by the parent switch, resulting in easier troubleshooting and centralized management.
  D. Cisco FEX devices do not have to be upgraded when the parent switch is upgraded, resulting in cost savings.
  E. Cisco FEX devices can be part of two different VDCs.
  C. Traffic-forwarding decisions are made by the parent switch, resulting in easier troubleshooting and centralized management.
  D. Cisco FEX devices do not have to be upgraded when the parent switch is upgraded, resulting in cost savings.

• Question 602:

  Which protocol should be run on the LAN side of two edge routers (that are terminating primary and backup WAN circuits) to provide quick failover in case of primary WAN circuit failure?

  A. VTP
  B. STP
  C. VRRP
  D. RIP
  C. VRRP

• Question 603:

  What is an advantage of having an out-of-band management?

  A. It is less expensive to have an out-of-band management.
  B. Network devices can still be managed, even in case of network outage.
  C. There is no separation between the production network and the management network.
  D. SSH protocol must be used to manage network devices.
  B. Network devices can still be managed, even in case of network outage.

• Question 604:

  Which two options are advantages of having a modular design instead of an EOR design in a data center? (Choose two.)

  A. cooling constraints
  B. cable bulk
  C. decreased STP processing
  D. redundancy options
  E. cost minimization
  F. low-skilled manager
  A. cooling constraints
  B. cable bulk

  ---

  There are some disadvantages with EOR designs:

  Cable bulk: More cabling needs to be routed and managed.

  Cooling constraints: The cable bulk at the cabinet floor entry can be difficult to manage and can block cool airflow.

  NOTE for your learnings:

  There are several advantages with EOR designs:

  Decreased management complexity: There are fewer devices to manage, which makes this task less complex. Decreased STP processing: With fewer devices in the Layer 2 infrastructure and significantly fewer uplinks, there is less impact

  on STP processing. Redundancy options: Redundant switch power and CPUs can be supported on modular switches.

• Question 605:

  Which command can you enter to inject BGP routes into an IGP?

  A. redistribute bgp
  B. redistribute static
  C. redistribute static subnet
  D. default-information originate
  A. redistribute bgp

• Question 606:

  Due to audit requirements, a medical center wants to ensure that only authorized personnel can make changes on network equipment within the company. In addition, only specific engineers are permitted access to change security settings on these devices.

  Which function must engineers utilize to ensure that these requirements are met?

  A. SNMP community strings
  B. Role Based Access Control
  C. RADIUS Secret
  D. VTY access control lists
  B. Role Based Access Control

• Question 607:

  Which technology is an example of the need for a designer to clearly define features and desired performance when designing advanced WAN services with a service provider?

  A. FHRP to remote branches
  B. Layer 3 MPLS VPNs secure routing
  C. Control protocols (for example Spanning Tree Protocol) for a Layer 3 MPLS service
  D. Intrusion prevention, QoS, and stateful firewall support network wide
  C. Control protocols (for example Spanning Tree Protocol) for a Layer 3 MPLS service

  ---

  This answer is an example that show that the designer did not clearly defined his needs because the SP gave a L3 service when L2 was needed.

• Question 608:

  Which two actions can be taken on Cisco LAN Switches to provide basic denial-of-service protection? (Choose two.)

  A. Disable Spanning Tree Protocol
  B. Disable PortFast
  C. Enable BPDU Guard
  D. Enable IP Source Guard
  E. Enable DHCP Snooping
  C. Enable BPDU Guard
  E. Enable DHCP Snooping

• Question 609:

  Management has requested that all web traffic be filtered through a proxy without the client's knowledge. Which mode does an engineer use to design the web proxy to accomplish this task without additional configuration on the web browser?

  A. explicit mode with PAC files
  B. transparent with WCCP
  C. explicit mode without PAC files
  D. transparent mode without WCCP
  B. transparent with WCCP

• Question 610:

  Which two protocols are used for high availability in enterprise networks? (Choose two.)

  A. BGP
  B. GLBP
  C. RSTP
  D. VRRP
  E. OSPF
  B. GLBP
  D. VRRP
