• Question 872:

  Refer to the exhibit. Which two prefixes are included in this routing table entry? (Choose two.)

  

  A. 192.168.1.17

  B. 192.168.1.61

  C. 192.168.1.64

• Question 873:

  Refer to the exhibit. When PC-A sends traffic to PC-B, which network component is in charge of receiving the packet from PC-A verifying the IP addresses, and forwarding the packet to PC-B?

  

  A. Layer 2 switch

  B. Router

  C. Load balancer

  D. firewall

  Correct Answer: B

  PC--A and PC-B are not in the same network. Switches send traffic in layer 2 and within the same VLA while routers route traffic to different subnet and at layer 3.

• Question 874:

  An engineering team asks an implementer to configure syslog for warning conditions and error conditions. Which command does the implementer configure to achieve the desired result?

  A. logging trap 5

  B. logging trap 2

  C. logging trap 4

  D. logging trap 3

  Correct Answer: C

• Question 875:

  Which two protocols are supported on service-port interfaces? (Choose two.)

  A. RADIUS

  B. TACACS+

  C. SCP

  D. Telnet

  E. SSH

  Correct Answer: DE

• Question 876:

  Refer to the exhibit.

  

  How must router A be configured so that it only sends Cisco Discovery Protocol Information to router C?

  A. #config t Router A(config)#cdp run Router A(config)#interface gi0/0/0 Router A(config-if)#no cdp enable

  B. #config t Router A(config)#cdp run Router A(config)#interface gi0/0/0 Router A(config-if)#cdp enable

  C. #config t Router A(config)#cdp run Router A(config)#interface gi0/0/1 Router A(config-if)#cdp enable

  D. #config t Router A(config)#no cdp run Router A(config)#interface gi0/0/1 Router A(config-if)#cdp enable

  Correct Answer: A

  Router(config)# no cdp run Router(config)# end Router# show cdp % CDP is not enabled Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface TenGigabitEthernet4/1 Router(config-if)# cdp enable % Cannot enable CDP on this interface, since CDP is not running Router(config-if)#

• Question 877:

  Which global command encrypt all passwords in the running configuration?

  A. password-encrypt

  B. enable password-encryption

  C. enable secret

  D. service password-encryption

  Correct Answer: D

• Question 878:

  What is the function of a hub-and-spoke WAN topology?

  A. allows access restrictions to be implemented between subscriber sites.

  B. provides direct connections between subscribers

  C. supports Layer 2 VPNs

  D. supports application optimization

  Correct Answer: B

• Question 879:

  Which protocol is used in Software Defined Access (SDA) to provide a tunnel between two edge nodes in different fabrics?

  A. Generic Router Encapsulation (GRE)

  B. Virtual Local Area Network (VLAN)

  C. Virtual Extensible LAN (VXLAN)

  D. Point-to-Point Protocol (PPP)

  Correct Answer: C

  The SD(Cisco® Software-Defined Access)-Access fabric uses the VXLAN data plane to provide transport of the full original Layer 2 frame and additionally uses LISP as the control plane to resolve endpoint-to-location (EID-to-RLOC) mappings. The SD-Access fabric replaces sixteen (16) of the reserved bits in the VXLAN header to transport up to 64,000 SGTs using a modified VXLAN-GPO (sometimes called VXLAN-GBP) format described in https://tools.ietf.org/html/ draft-smith-vxlan-group-policy-04.

• Question 880:

  Refer to the exhibit.

  

  The entire contents of the MAC address table are shown. Sales-4 sends a data frame to Sales-1.

  

  What does the switch do as it receives the frame from Sales-4?

  A. Perform a lookup in the MAC address table and discard the frame due to a missing entry.

  B. Insert the source MAC address and port into the forwarding table and forward the frame to Sales-1.

  C. Map the Layer 2 MAC address to the Layer 3 IP address and forward the frame.

  D. Flood the frame out of all ports except on the port where Sales-1 is connected.

  Correct Answer: B
