• Question 942:

  What are two functions of a server on a network? (Choose two)

  A. achieves redundancy by exclusively using virtual server clustering

  B. runs applications that send and retrieve data for workstations that make requests

  C. handles requests from multiple workstations at the same time

  D. runs the same operating system in order to communicate with other servers

  E. housed solely in a data center that is dedicated to a single client

  Correct Answer: BC

• Question 943:

  Refer to the exhibit.

  

  An engineer configured the New York router with static routes that point to the Atlanta and Washington sites. Which command must be configured on the Atlanta and Washington routers so that both sites are able to reach the loopback2 interface on the New York router?

  A. ipv6 route ::/0 Serial 0/0/1

  B. ipv6 route 0/0 Serial 0/0/0

  C. ipv6 route ::/0 Serial 0/0/0

  D. ip route 0.0.0.0.0.0.0.0 Serial 0/0/0

  E. ipv6 route ::/0 2000::2

  Correct Answer: C

• Question 944:

  Which state does the switch port move to when PortFast is enabled?

  A. forwarding

  B. listening

  C. blocking

  D. learning

  Correct Answer: A

• Question 945:

  Which function is performed by the collapsed core layer in a two-tier architecture?

  A. enforcing routing policies

  B. marking interesting traffic for data polices

  C. attaching users to the edge of the network

  D. applying security policies

  Correct Answer: A

  In a two-tier network architecture, the collapsed core layer typically combines the core and distribution layers of a three-tier architecture into a single layer. The main function of the collapsed core layer is to provide high-speed switching and routing of traffic between the distribution layer switches and the access layer switches. Therefore, the answer to your question is A. enforcing routing policies.

• Question 946:

  A port security violation has occurred on a switch port due to the maximum MAC address count being exceeded. Which command must be configured to increment the security-violation count and forward an SNMP trap?

  A. switchport port-security violation access

  B. switchport port-security violation protect

  C. switchport port-security violation restrict

  D. switchport port-security violation shutdown

  Correct Answer: C

• Question 947:

  What is a recommended approach to avoid co-channel congestion while installing access points that use the 2.4 GHz frequency?

  A. different nonoverlapping channels

  B. different overlapping channels

  C. one overlapping channel

  D. one nonoverlapping channel

  Correct Answer: A

  The correct answer to the question "What is a recommended approach to avoid co-channel congestion while installing access points that use the 2.4 GHz frequency?" is:

  A. different non-overlapping channels

  This is a commonly recommended approach to avoid co-channel interference when deploying multiple access points that use the 2.4 GHz frequency band . Channels 1, 6, and 11 are non-overlapping channels that are commonly used for this

  purpose.

  Options B, C, and D are not recommended because they involve using overlapping channels, which can lead to interference and reduced performance.

• Question 948:

  Refer to the exhibit. Which type of configuration is represented in the output?

  

  A. Ansible

  B. JSON

  C. Chef

  D. Puppet

  Correct Answer: D

  Reference: https://forge.puppet.com/modules/puppetlabs/ciscopuppet/1.0.0

• Question 949:

  Which cloud service model does the engineer recommend?

  A. infrastructure-as-a-service

  B. platform-as-a-service

  C. business process as service to support different types of service

  D. software-as-a-service

  Correct Answer: D

  The cloud service model that the network engineer would recommend for employees to avoid wasting time installing, managing, and updating software that is only used occasionally is "software-as-a-service" (SaaS).

• Question 950:

  Which spanning-tree enhancement avoids the learning and listening states and immediately places ports in the forwarding state?

  A. BPDUfilter

  B. PortFast

  C. Backbonefast

  D. BPDUguard

  Correct Answer: B

  PortFast

  Spanning Tree Portfast causes layer 2 switch interfaces to enter forwarding state immediately, bypassing the listening and learning states. It should be used on ports connected directly to end hosts like servers or workstations. Note: If portfast

  isn't enabled, DHCP timeouts can occur while STP converges, causing more problems.
