• Question 252:

  Refer to the exhibit. After the code is run on a Cisco IOS-XE router, the response code is 204.

  What is the result of the script?

  

  A. The configuration fails because another interface is already configured with IP address 10.10.10.1/24.
  B. The configuration fails because interface GigabitEthernet2 is missing on the target device.
  C. The configuration is successfully sent to the device in cleartext.
  D. Interface GigabitEthernet2 is configured with IP address 10.10.10.1/24
  D. Interface GigabitEthernet2 is configured with IP address 10.10.10.1/24

• Question 253:

  When a wireless client roams between two different wireless controllers, a network connectivity outage is experienced for a period of time.

  Which configuration issue would cause this problem?

  A. Not all of the controllers in the mobility group are using the same mobility group name.
  B. Not all of the controllers within he mobility group are using the same virtual interface IP address.
  C. All of the controllers within the mobility group are using the same virtual interface IP address.
  D. All of the controllers in the mobility group are using the same mobility group name.
  B. Not all of the controllers within he mobility group are using the same virtual interface IP address.

  ---

  Explanation

  A prerequisite for configuring Mobility Groups is "All controllers must be configured with the same virtual interface IP address". If all the controllers within a mobility group are not using the same virtual interface, inter-controller roaming may appear to work, but the handoff does not complete, and the client loses connectivity for a period of time. -> Answer B is correct.

• Question 254:

  Refer to the exhibit.

  

  An engineer must send the 172.16.2.0 /24 user traffic to a packet capture tool to troubleshoot an issue.

  Which action completes the configuration?

  A. Encrypt the traffic between the users and the monitoring servers.
  B. Disable the spanning tree protocol on the monitoring server VLAN.
  C. Enable the Cisco Discovery Protocol on the server interfaces.
  D. Define the remote span VLAN on SW1 and SW2.
  D. Define the remote span VLAN on SW1 and SW2.

• Question 255:

  An engineer is concerned with the deployment of a new application that is sensitive to inter-packet delay variance.

  Which command configures the router to be the destination of jitter measurements?

  A. Router(config)# ip sla responder udp-connect 172.29.139.134 5000
  B. Router(config)# ip sla responder tcp-connect 172.29.139.134 5000
  C. Router(config)# ip sla responder udp-echo 172.29.139.134 5000
  D. Router(config)# ip sla responder tcp-echo 172.29.139.134 5000
  C. Router(config)# ip sla responder udp-echo 172.29.139.134 5000

  Explanation

  Cisco IOS IP SLA Responder is a Cisco IOS Software component whose functionality is to respond to Cisco IOS IP SLA request packets. The IP SLA source sends control packets before the operation starts to establish a connection to the responder. Once the control packet is acknowledged, test packets are sent to the responder. The responder inserts a time-stamp when it receives a packet and factors out the destination processing time and adds time-stamps to the sent packets. This feature allows the calculation of unidirectional packet loss, latency, and jitter measurements with the kind of accuracy that is not possible with ping or other dedicated probe testing.

  References:

  UDP Jitter measures the delay, delay variation (jitter), corruption, misordering and packet loss by generating periodic UDP traffic. This operation always requires IP SLA responder. The command to enable UDP Jitter Operation is "ip sla responder udp-echo {destination-ip-address} [destination-port]

• Question 257:

  Which characteristics applies to Cisco SD-Access?

  A. It uses dynamic routing to discover and provision the border and edge switches
  B. It uses VXLAN for the control plane
  C. It uses PnP to discover and provision border and access switches
  D. It uses GRE tor the policy plane
  C. It uses PnP to discover and provision border and access switches

• Question 258:

  What is a type 2 hypervisor?

  A. Installed as an application on an already installed operating system.
  B. Runs directly on a physical server and includes its own operating system.
  C. Supports over-allocation of physical resources.
  D. Also referred to as a "bare metal hypervisor" because it sits directly on the physical server.
  A. Installed as an application on an already installed operating system.

• Question 259:

  How must network management traffic be treated when defining QoS policies?

  A. as delay-sensitive traffic in a low latency queue
  B. using minimal bandwidth guarantee
  C. using the same marking as IP routing
  D. as best effort
  A. as delay-sensitive traffic in a low latency queue

  ---

  Explanation

  Low latency queuing (LLQ) adds a priority queue to CBWFQ from which delay-sensitive traffic, such as voice traffic, can be transmitted ahead of packets in other queues. By configuring the quality of service (QoS), you can provide preferential treatment to specific types of traffic at the expense of other traffic types. Without QoS, the device offers best-effort service for each packet, regardless of the packet contents or size. The device sends the packets without any assurance of reliability, delay bounds, or throughput.

  The following are specific features provided by QoS:

  * Low latency

  * Bandwidth guarantee

  * Buffering capabilities and dropping disciplines

  * Traffic policing

  * Enables the changing of the attribute of the frame or packet header

  * Relative services

  * Modular QoS Command-Line Interface

  * Supported QoS Features for Wired Access

  * Hierarchical QoS

• Question 260:

  B. IPsec
  C. PGP
  D. HTTPS
  A. DTLS
