Q243. How does TACACS+ facilitate secure connections for user access to network routers?

Q244.

Refer to the exhibit. If the NetFlow configuration is updated to version 9, which additional piece of information can be reported?

Q245. A network engineer is testing an automation platform that interacts with Cisco networking devices via NETCONF over SSH. In accordance with internal security requirements:
– NETCONF sessions are permitted only from trusted sources in the
172.16.20.0/24 subnet.
– CLI SSH access is permitted from any source.
Which configuration must the engineer apply on R1?

Q246. Which two PHY modes are available to implement an IOS XR Gigabit Ethernet interface interface? (Choose two.)

Q247. An engineer must extend Layer 2 Between two campus sites connected through an MPLS backbone that encapsulates Layer 2 and Layer 3 data.
Which action must the engineer perform on the routers to accomplish this task?

Q248. An organization with big data requirements is implementing NETCONF as part of its migration to a new cloud-based environment. The organization has multiple offices across widespread geography. A network engineer is configuring NETCONF on one of the border routers. Which configuration must the engineer apply to save the running configuration?

Q249. Refer to the exhibit:

Assume all other configurations are correct and the network is otherwise operating normally. Which conclusion can you draw about the neighbor relationship between routers R1 and R2?

Q250.

Refer to the exhibit. A regional company is implementing a network-health monitoring solution on their Cisco ISR routers to monitor network performance metrics and gather real-time data. The router R1 Ethernet interface, GigabitEthernet0/0, is assigned IP address 192.168.1.1/24, and basic IP addressing and connectivity to the data-collection server have already been configured. A network engineer must update R1 to ensure secure and reliable data transmission to the monitoring server, which is located at IP address 192.168.50.50 on port 50051. To achieve secure communication, the configuration must comply with RFC 5246, and to ensure reliable data transmission, it must follow RFC 793. Which command must the engineer execute to configure data collection?

Q251. Refer to the exhibit A user is performing QoS marking on internet traffic and sending it with IPv4 and IPv6 headers on the provider edge device PE1. IPv4 traffic is classified with DSCP 4 and IPv6 traffic is classified with DSCP 6. Which action must the engineer take to begin implementing a QoS configuration on PE1 for the IPv6 traffic?

Q252. What is the function of the FEC filed within the OTN signal structure?

Q253. Refer to the exhibit.

What does the REST API command do?

Q254. Refer to the exhibit.

Refer to the exhibit. An engineer working for a private telecommunication company with an employee id: 3414:81:713 is implementing this network, in which:
Routers R1A and R1B are eBGP neighbors.
iBGP is configured within AS 65515 and AS 65516.
Network 192.168.2.0/24 is shared with AS 65516.
Router R3A has an iBGP relationship with router R2A only.
Router R2A has an iBGP relationship with routers R1A and R3A.
Which additional task must the engineer perform to complete the configuration?

Q255. An engineer working for a telecommunication company with an employee ID: 4460:35:466 must configure an OSPF router in a multivendor network so that it performs NSF in the event of a route processor switchover. Which configuration must the engineer apply?

Q256. What is an enhancement that Cisco IOS XE Software has over Cisco IOS Software?

Q257. Which two features will be used when defining SR-TE explicit path hops if the devices are using IP unnumbered interfaces? (Choose two.)

Q258. Drag and drop the LDP features from the left onto the correct usages on the right.

Q259. A network engineer uses the REST NBI to configure routers in the network. Routers on the network are frequently assigned new process IDs as the network expands. The engineer already enabled syslog logging on all routers.
Which configuration must the engineer apply on R3 so that future changes to its OSPF process ID are logged?

Q260. Refer to the exhibit. EIGRP is running between routers R5 and R1, and OSPF is used in the rest of the network. Users in a network attached to router R3 need to access a server connected to R5. Which task must the engineer perform so that only the users attached to R3 are able to access the server, but no other network is shared to OSPF?
