What are three indicators of a cabling issue on a switch? (Choose three.)
invalid frame size
A network administrator keeps receiving "%SYS−2−MALLOCFAIL" console messages. Further investigation reveals that the buffer pool continues to grow. The CCO knowledge base identified the cause of the problem as a result of a buffer memory leak due to an IOS software bug. What should the administrator do to rectify this problem?
Change the configuration register settings to bypass the loading of the startup configuration file.
Upgrade the Cisco IOS software to a version that fixes the issue.
Reinstall older Cisco IOS software.
Reload the router.
Change the configuration register settings to bypass the loading of the IOS.
Power down the router and wait a few minutes before reloading it.
Refer to the exhibit. What can be determined from the exhibited output?
The interface is performing normally.
There is a physical layer problem.
There is an unacceptable level of input errors.
The Frame Relay PVC is not established.
Which three Cisco packet switching methods must a network administrator be familiar with in order to troubleshoot a router performance issue that is related to the switching path? (Choose three.)
Cisco Express Forwarding (CEF)
A network administrator plans to implement QoS in the network by using the Cisco AutoQoS tool. What should be done in the first phase of the automation process?
Cisco Express Forwarding should be disabled on each target interface by the use of the no ip cef command.
Via the use of the ip nbar protocol-discovery command, each interface should be configured to gather information about the applications that are known to NBAR.
The network device should be configured to capture network traffic statistics via the use of the autodiscovery qos interface configuration command.
In order to apply QoS policies, each interface should be configured with the auto qos command.
Refer to the exhibit. A network administrator is troubleshooting the switching path on a router. Based on the exhibited output, what can be concluded?
Switching has been disabled.
Fast switching has been enabled.
Process switching has been enabled.
Cisco Express Forwarding (CEF) has been implemented.
Refer to the exhibit. What can be determined about the operation of interface FastEthernet 0/2?
It has a duplex mismatch with the connected device.
It is operating within acceptable limits.
It is carrying 802.1Q formatted frames.
It is connected to a hub.
What must a system administrator do to allow NBAR to recognize a new protocol without having to upgrade the Cisco IOS image?
Load an appropriate Packet Description Language Module (PDLM).
Upgrade the version of NBAR that is running on the device.
Enable the autodiscovery feature on the interface.
Because NBAR will automatically discover new applications, the administrator does not need to do anything.
Refer to the exhibit. A network administrator has noticed that the IP SLA probe did not run as expected.What should the administrator do to correct this problem?
Configure the router as a stratum 1 time source.
Remove the forever keyword from the configuration.
Configure NTP on the router to point to a different time source.
Adjust the clock frequency on R1.
What reported error counter describes frames that do not end with an integral number of octets and have a bad cyclic redundancy check (CRC)?
Refer to the exhibit. A network administrator is investigating performance issues of the access switch. On the basis of the provided outputs, what conclusion can be made about the switch performance?
The ratio between the FCS errors and the number of received errors is normal and does not require further investigation.
The ratio between the FCS errors and the number of giant frames that are received on the switch is excessively high and requires further investigation.
The ratio between the FCS errors and the number of unicast, broadcast, and multicast traffic frames that are received on the switch is excessively high and requires further investigation.
The ratio between the FCS errors and the number of broadcast and multicast traffic frames that are received on the switch is normal and does not require further investigation.
Refer to the exhibit. Users on the network are complaining that transferring large files to the SRV1 server takes hours. A network administrator runs a few tests on both switches to investigate the problem. On the basis of the provided outputs, what could be the possible reason for problem?
An unsupported Auto-MDIX feature on both switches is causing a high volume of multi collisions.
Slow STP convergence is causing a high volume of single collisions on DSW_1.
A duplex mismatch is causing a high volume of late collisions on DSW_1.
High CPU utilization is causing excessive FCS errors on ASW_1.
Refer to the exhibit. A network administrator enables AutoQoS on a PPP link that is currently active. Once AutoQoS is enabled the link goes down. What should the administrator do to correct this problem?
Investigate the configured bandwidth on the PPP link to ensure it is sufficient, then remove and reapply the AutoQoS configuration.
Change the encapsulation to HDLC because AutoQoS does not support PPP.
Decrease the multilink threshold value to allow AutoQoS to run
Disable multilink on the PPP connection.
Refer to the exhibit. Based on the output of the show interfaces command, which two statements are true?(Choose two.)
The interface is currently shutdown.
The interface has been configured with the no ip route-cache command.
This is an example of a wedged interface.
The interface is displaying symptoms of a buffer leak.
The serial interface is being subjected to a denial of service (DoS) attack.
A network is experiencing performance degradation on an access switch where user traffic is subject to granular QoS policy and security inspection. Which switch component or components should be inspected by the network administrator to help determine the issue?
the forwarding plane only
the forwarding plane and the control plane
the egress interfaces only
the ingress and egress interfaces, the forwarding plane, and the control plane
the ingress interfaces only
the control plane only
A network administrator wishes to use debug commands to observe how a router processes each individual packet on an interface. Which packet switching solution should be implemented on the interface to accomplish this task?
Enable fast switching using the no ip route-cache command.
Enable process switching using the no ip route-cache command.
Enable Cisco Express Forwarding (CEF) using the ip cef command.
Enable process switching using the ip route-cache command.
Enable Cisco Express Forwarding (CEF) using the no ip cef command.
Enable fast switching using the ip route-cache command.
Which three hardware components are common in the architectures of all Catalyst switch families?(Choose three.)
control plane hardware
A network administrator has configured a Cisco IOS device to provide server load balancing (SLB) for the corporate web server. What is required on the client side to ensure proper load balancing?
Clients must be readdressed so that they are equally distributed throughout the network address space.
Port numbers should be added to each client request in order to get routed to the correct server.
Clients should initiate connections to the virtual IP address (VIP).
Clients should initiate connections to the IP address of the predictor.
How can an administrator determine if a memory leak is present in a router?
The show diagnostics command will show that the DRAM size has reached maximum capacity.
The show buffers command will show no free buffers.
The show memory allocating-process totals command will show low free space.
The show interface command will show that the input queue has reached the maximum capacity.
What can cause a memory leak on a router?
incorrect configuration registry code
an IOS bug
too many remote users logged into the router
