Question 381
Refer to the exhibit.
An engineer must allow all users in the 10.2.2.0/24 subnet to access the Internet. To conserve address space the public Interface address of 209 165 201.1 must be used for all external communication. Which command set accomplishes these requirements?
Question 382
Which benefit is realized by implementing SSO?
IP first-hop redundancy
communication between different nodes for cluster setup
physical link redundancy
minimal network downtime following an RP switchover
Question 383
Refer to the exhibit.
The administrator troubleshoots an EtherChannel that keeps moving to err-disabled. Which two actions must be taken to resolve the issue? (Choose two.)
Reload the switch to force EtherChannel renegotiation
Ensure that interfaces Gi1/0/2 and Gi1/0/3 connect to the same neighboring switch.
Ensure that the switchport parameters of Port channel1 match the parameters of the port channel on the neighbor switch
Ensure that the corresponding port channel interface on the neighbor switch is named Portchannel1.
Ensure that the neighbor interfaces of Gi1/0/2 and Gi/0/3 are configured as members of the same EtherChannel
Causes of Errdisable
This feature was first implemented in order to handle special collision situations in which the switch detected excessive or late collisions on a port. Excessive collisions occur when a frame is dropped because the switch encounters 16 collisions in a row. Late collisions occur after every device on the wire should have recognized that the wire was in use. Possible causes of these types of errors include:
A cable that is out of specification (either too long, the wrong type, or defective) A bad network interface card (NIC) card (with physical problems or driver problems) A port duplex misconfiguration A port duplex misconfiguration is a common cause of the errors because of failures to negotiate the speed and duplex properly between two directly connected devices (for example, a NIC that connects to a switch). Only half-duplex connections should ever have collisions in a LAN. Because of the carrier sense multiple access (CSMA) nature of Ethernet, collisions are normal for half duplex, as long as the collisions do not exceed a small percentage of traffic.
Question 384
What Is the difference between the MAC address table and TCAM?
The MAC address table supports partial matches. TCAM requires an exact match.
The MAC address table is contained in TCAM ACL and QoS information is stored in CAM.
Router prefix lookups happen in TCAM. MAC address table lookups happen In CAM.
TCAM is used to make L2 forwarding decisions. CAM is used to build routing tables
"TCAM is most useful for building tables for searching on longest matches such as IP routing tables organized by IP prefixes. The TCAM table stores ACL, QoS and other information generally associated with upper-layer processing. As a result of using TCAM, applying ACLs does not affect theperformance of the switch." https://community.cisco.com/t5/networking-documents/cam-content- addressable-memory-vs-tcam-ternary-content/ta-p/3107938
Question 385
Which two features does the Cisco SD-Access architecture add to a traditional campus network?
(Choose two.)
software-defined segmentation
private VLANs
SD-WAN
modular QoS
identity services

Question 386
Refer to the exhibit.
An engineer must configure an ERSPAN session with the remote end of the session 10.10.0.1. Which commands must be added to complete the configuration?
Example: Configuring an ERSPAN Source Session on a WAN Interface
The following example shows how to configure more than one WAN interface in a single ERSPAN source monitor session. Multiple interfaces have been separated by a commas. monitor session 100 type erspan-source source interface
Serial 0/1/0:0, Serial 0/1/0:6 Example: Configuring an ERSPAN Destination Session The following example shows how to configure an ERSPAN destination session: monitor session 2 type erspan-destination destination interface
GigabitEthernet1/3/2 destination interface GigabitEthernet2/2/0 source erspan-id 100 ip address 10.10.0.1
Question 387
An engineer must configure a new loopback Interface on a router and advertise the interface as a fa4 in OSPF. Which command set accomplishes this task?
Step 1. Create the loopback interface using the interface loopback number global configuration command.
Step 2. Add a description. Although optional, it is a necessary component for documenting a network.
Step 3. Configure the IP address.
For example, the following commands configure a loopback interface of the R1 router shown in (shown earlier in the chapter):
R1# configure terminal
R1(config)# interface loopback 0
R1(config-if)# ip address 10.0.0.1 255.255.255.0
R1(config-if)# exit
R1(config)#
Question 388
Refer to the exhibit.
Which command set is needed to configure and verify router R3 to measure the response time from router R3 to the file server located in the data center?

Question 389
Refer to the exhibit.
Which configuration must be applied to the HQ router to set up a GRE tunnel between the HQ and BR routers?
Question 390
Refer to The exhibit.
Assuming that R1 is a CE router, which VRF is assigned to Gi0/0 on R1?
VRF VFN_A
VRF VPN_B
management VRF
default VRF
