• Question 112:

  The PE and CE interfaces are in the UP/UP state. The junior Network Engineer has validated Layer 3 functionality by pinging the adjacent interface, however the customer is unable to access the provider network. What should be your next troubleshooting step?

  A. Validate that the encapsulation method is utilizing Point-to-Point Protocol
  B. Validate that the destination customer network is in the correct VRF
  C. Validate that the circuit clocking is inaccurate and needs to be synchronized on both sides
  D. Check the physical connection between both devices to ensure stability
  E. Identify incorrect RADIUS configuration is present on the PE device
  F. Check that an access-list is mis-configured on the loopback 0 interface and needs to be corrected
  B. Validate that the destination customer network is in the correct VRF

• Question 113:

  A network engineer has configured an interface with various commands including the no shutdown command on an IOS-XR device. Both sides of the interface have been validated and the cable has been tested. Which command does the network engineer need to input?

  A. switch#copy running-configuration startup-configuration
  B. switch#commit config
  C. (config)#commit
  D. switch(config)#commit config
  E. switch#write memory
  C. (config)#commit

• Question 114:

  You are assessing a network design proposal for a new site which includes the following requirements:

  There are 252 users in three floors Each floor has an access wiring cabinet serving the connections on that floor The MDF is located in the basement and is connected to the IDFs via a resilient MM fiber A 1Gbps dedicated Internet connection terminates in the MDF

  The proposal specifies 2 Cisco Catalyst 2960X-48TD-L for each IDF and a single 2960X-48TS-L for the MDF to terminate the access connections and a Cisco Meraki MX400 Security Appliance. Which feedback should you give?

  A. The design is not valid because all Greenfield locations must be wireless first and so the design must be completely redone
  B. The design is not valid because the cabling must be cat6a to achieve 802.3ab speeds
  C. The design is not valid because the core 2960X-48TS-L has only four SFP ports, which means that the resilient fiber runs are wasted
  D. The design is valid but the Cisco Meraki MX400 must be replaces with a Cisco ASA firewall because you see no value in cloud-based networking
  C. The design is not valid because the core 2960X-48TS-L has only four SFP ports, which means that the resilient fiber runs are wasted

• Question 118:

  Which two statements about IPv4 DHCP operations are true? (Choose two.)

  A. If the DHCP clients and servers are on the same subnet, DHCP uses UDP broadcasts to communicate between the clients and servers.
  B. The DHCP server that receives a DHCPDISCOVER message may respond with a DHCPOFFER message on UDP port 67.
  C. A client can receive DHCPOFFER from multiple servers and it can accept all the offers by broadcasting the DHCPREQUEST message to all the servers.
  D. A DHCP relay is required if the DHCP clients and the servers are on the same subnet.
  E. If the client and server are on different subnets, DHCPDISCOVER and DHCPREQUEST messages are sent via UDP broadcasts, but DHCPOFFER and DHCPACK messages are unicast.
  F. The client broadcasts a DHCPDISCOVER message on UDP port 68 with its own MAC address to discover available DHCP servers.
  A. If the DHCP clients and servers are on the same subnet, DHCP uses UDP broadcasts to communicate between the clients and servers.
