• Question 512:

  An engineer is implementing MPLS OAM to monitor traffic within the MPLS domain.

  Which action must the engineer perform to prevent from being forwarded beyond the service provider domain when the LSP is down?

  A. Disable IP redirects only on outbound interfaces.
  B. Implement the destination address for the LSP echo request packet in the 127.x.y.z/8 network.
  C. Disable IP redirects on all ingress interfaces.
  D. Configure a private IP address as the destination address of the headend router of Cisco MPLS TE.
  C. Disable IP redirects on all ingress interfaces.

• Question 513:

  Refer to the exhibit.

  

  During ISP router maintenance, the network produced many alerts because of the flapping interface.

  Which configuration on R1 resolves the issue?

  A. snmp trap ip verify drop-rate
  B. no snmp trap link-status
  C. ip verify drop-rate notify hold-down 60
  D. snmp trap link-status down
  B. no snmp trap link-status

  ---

  Explanation

  The command "snmp trap link-status" (and "no" form) enables or disable the sending of SNMP traps when an interface goes up and down. This command is useful on interfaces that you expect to change state frequently (for example, dial-on-demand interfaces). You may not want to send an SNMP trap to your network management stations whenever these interfaces change state.

  The command "ip verify drop-rate notify hold-down ..." configures the minimum time, in seconds, between Unicast RPF drop-rate notifications. But RPF is not a concern in this question.

• Question 514:

  Which statement explains why Type 1 hypervisor is considered more efficient than Type 2 hypervisor?

  A. Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS.
  B. Type 1 hypervisor enables other operating systems to run on it.
  C. Type 1 hypervisor relics on the existing OS of the host machine to access CPU, memory, storage, and network resources.
  D. Type 1 hypervisor is the only type of hypervisor that supports hardware acceleration techniques.
  A. Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS.

  ---

  Explanation

  There are two types of hypervisors: type 1 and type 2 hypervisor. In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server. Then instances of an operating system (OS) are installed on the hypervisor.

  Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V. In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. answer 'Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS' big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows).

  

• Question 515:

  Which two namespaces does the LISP network architecture and protocol use? (Choose two.)

  A. TLOC
  B. RLOC
  C. DNS
  D. VTEP
  E. EID
  B. RLOC
  E. EID

  ---

  Explanation

  Locator ID Separation Protocol (LISP) is a network architecture and protocol that implements the use of two namespaces instead of a single IP address: + Endpoint identifiers (EIDs)--assigned to end hosts. + Routing locators (RLOCs)-- assigned to devices (primarily routers) that make up the global routing system.

• Question 516:

  A network administrator received reports that a 40Gb connection is saturated. The only server the administrator can use for data collection in that location has a 10Gb connection to the network.

  Which of the following is the best method to use on the server to determine the source of the saturation?

  A. Port mirroring
  B. Log aggregation
  C. Flow data
  D. Packet capture
  C. Flow data

  ---

  Explanation

  This is because flow data is a method of collecting and analyzing information about the traffic flows on a network. Flow data can provide details such as the source and destination IP addresses, ports, protocols, and bytes transferred for each flow. Flow data can help identify the source of the saturation by showing which hosts and applications are generating or consuming the most bandwidth. Flow data can be collected using protocols such as NetFlow, IPFIX, or sFlow. The source of this answer is the Cisco ENCOR v1.1 course, module 10, lesson 10.1: Implementing NetFlow and IPFIX.

• Question 517:

  Which two protocols are used with YANG data models? (Choose two.)

  A. HTTPS
  B. SSH
  C. RESTCONF
  D. TLS
  E. NFTCONF
  C. RESTCONF
  E. NFTCONF

  ---

  Explanation

  YANG (Yet Another Next Generation) is a data modeling language for the definition of data sent over network management protocols such as the NETCONF and RESTCONF.

• Question 518:

  What is a benefit of deploying an on-premises infrastructure versus a cloud infrastructure deployment?

  A. faster deployment times because additional infrastructure does not need to be purchased
  B. lower latency between systems that are physically located near each other
  C. less power and cooling resources needed to run infrastructure on-premises
  D. ability to quickly increase compute power without the need to install additional hardware
  B. lower latency between systems that are physically located near each other

  ---

  Explanation

  The difference between on-premise and cloud is essentially where this hardware and software resides. On-premise means that a company keeps all of this IT environment onsite either managed by themselves or a third-party. Cloud means that it is housed offsite with someone else responsible for monitoring and maintaining it.
