  R2 is the neighboring router of R1. R2 receives an advertisement for network 192 168.10.50/32.

  Which configuration should be applied for the subnet to be advertised with the original /24 netmask?

  A. R1(config)# router ospf 1 R1(config-router)# network 192.168.10.0 255.255.255.0 area 0
  B. R1(config)#interface loopback0 R1(confia-if)# ip ospf 1 area 0
  C. R1(config)# interface loopback0 R1(config-if)# ip ospf network point-to-point
  D. R1(config)# interface loopback0 R1(config-if)# ip ospf network non-broadcast
  C. R1(config)# interface loopback0 R1(config-if)# ip ospf network point-to-point

  Explanation

  Loopback Networks

  The OSPF network type loopback is enabled by default for loopback interfaces and can be used only on loopback interfaces. The OSPF loopback network type states that the IP address is always advertised with a /32 prefix length, even if the IP address configured on the loopback interface does not have a /32 prefix length. It is possible to demonstrate this behavior by reusing Figure 8-11 and advertising a Loopback 0 interface. Example 8-21 provides the updated configuration. Notice that the network type for R2's loopback interface is set to the OSPF point-to-point network type.

• Question 835:

  Which virtualization component creates VMs and performs hardware abstraction that allows multiple VMs to run at the same time?

  A. container
  B. Docker
  C. hypervisor
  D. rkt
  C. hypervisor

• Question 836:

  In lhe Cisco DNA Center Image Repository, what is a golden image?

  A. The latest software image that is available for a specific device type
  B. The Cisco recommended software image for a specific device type.
  C. A software image that is compatible with multiple device types.
  D. A software image that meets the compliance requirements of the organization.
  B. The Cisco recommended software image for a specific device type.

  ---

  Explanation

  Cisco DNA Center allows you to designate software images and SMUs as golden. A golden software image or SMU is a validated image that meets the compliance requirements for the particular device type.

• Question 837:

  Which tunnel type allows clients to perform a seamless Layer 3 roam between a Cisco AireOS WLC and a Cisco IOS XE WLC?

  A. Ethernet over IP
  B. IPsec
  C. Mobility
  D. VPN
  C. Mobility

• Question 838:

  Which feature works with SSO to continue forwarding packets after a route processor failure until the control plane recovers?

  A. ECMP
  B. HSRP
  C. RSVP
  D. NSF
  D. NSF

• Question 839:

  What does Cisco Cyber Threat Defense provide visibility into?

  A. Security threats based on log messages and telemetry information
  B. User-stored data and internal dependencies for the user's running programs
  C. Network software vulnerabilities through continuous scan probes in the network
  D. Command-and-control traffic on the communication channel between compromised hosts and attackers
  D. Command-and-control traffic on the communication channel between compromised hosts and attackers

  ---

  Explanation

  The correct answer is Option D. Command-and-control traffic on the communication channel between compromised hosts and attackers.

  Cisco Cyber Threat Defense uses network telemetry to provide visibility into suspicious and anomalous activity across the network. Cisco documentation lists botnet command-and-control channel detection as one of the threat-detection tasks supported by Cisco Cyber Threat Defense.

  Option A is too broad and does not specifically identify the visibility function described here.

  Option B is unrelated to Cisco Cyber Threat Defense.

  Option C is incorrect because Cisco Cyber Threat Defense is not primarily a continuous vulnerability scanning solution.

• Question 840:

  What is the VXLAN network identifier used to identify?

  A. network tunnel interface
  B. IP subnet
  C. virtual tunnel endpoint
  D. broadcast domain
  D. broadcast domain
