An engineer working for telecommunication company with an employee id: 3715 15 021 needs to secure the LAN network using a prefix list Which best practice should the engineer follow when he implements a prefix list?
Refer to the exhibit.
A NOC engineer is configuring label-based forwarding from CSR to the EPC gateway. Cell-site operation and maintenance for IPv4 traffic between 10.20.10.1 and 192.168.10.10 is already up. CR1 and CR2 are configured as route reflectors for AG1 and AG2. Which action completes the configuration?
Refer to the exhibit. The network is running OSPF, and access to the internet is provided through router RB. Router RA connects to several servers that provide services to users connected to RC and RF. User traffic is growing, and the engineering team wants to mitigate the future potential for congestion when the servers are experiencing heavy use.
Which action must the team take to maintain better network performance?
Refer to the exhibit:
P3 and PE4 are at the edge of the service provider core and serve as ABR routers Aggregation areas are on either side of the core.
Which statement about the architecture is true?
Refer to the exhibit. Customer C-101 in ASN 65123 requested that the ISP blackholes a host route 198.19.44.195, to which the customer is receiving a significant amount of malicious traffic. Which configuration must the network engineer implement on the trigger router TR-1 to fulfill the request without affecting other IP destinations in the customer's block?
Refer to the exhibit.
While troubleshooting the OSPF adjacency between routers R1 and R2 an engineer noticed that both routers are stuck in the EXCHANGE/EXSTART state. What should the engineer fix to solve the ongoing issue?
Refer to the exhibit:
This configuration is being applied on an IOS XR router.
Which statement about this configuration is true?
An engineer must apply an 802.1ad-compliant configuration to a new switchport with these requirements:
The switchport must tag all traffic when it enters the port.
The switchport is expected to provide the same level of service to traffic from any customer VLAN.
Which configuration must the engineer use?
A network engineer must implement an ACL-based solution to mitigate availability issues on a web service that is hosted on a server at IP address 172.16.15.18/23. Access to the web server should be allowed over HTTP from RFC 1918 addresses only. The network architect has already enabled PMTUD in the network. Which ACL configuration must the engineer implement to complete the task?
Refer to the exhibit.
What reestablishes the OSPF neighbor relationship between Router 1 and Router 2?
Which action occurs during the traceback phase of the six-phase approach to service provider security?
