Question 6 of 253
You are deploying OSPF on a point-to-multipoint Frame Relay network. The remote sites do not need to be able to communicate with each other and there are a relatively small number of sites (scaling is not a concern).
How should you configure OSPF for this topology to minimize the additional routing information injected into the network and keep the configuration size and complexity to a minimum?
How should you configure OSPF for this topology to minimize the additional routing information injected into the network and keep the configuration size and complexity to a minimum?
Correct Answer: A
Configuring the link at the hub router as OSPF point-to-multipoint and at the remote routers as OSPF point-to-point minimizes additional routing information and keeps the configuration size and complexity to a minimum. This approach works well in a Frame Relay point-to-multipoint network where the remote sites do not need to communicate with each other. OSPF point-to-multipoint mode will treat each connection between the hub and the remote sites as a separate point-to-point link, simplifying the topology and reducing unnecessary routing information.
Question 7 of 253
Which two practices should you implement to increase SNMPv1 security? (Choose two.)
Correct Answer: B, C
To increase SNMPv1 security, you should use access control lists (ACLs) to allow only specific IP addresses to poll SNMP, which limits access to trusted parties. Additionally, using a combination of alphanumeric characters for the community strings can make them more difficult to guess or brute-force, thereby enhancing security.
Question 8 of 253
Refer to the exhibits. You have been asked to review a proposal for adding redundancy to the non-redundant network in Exhibit 1. Exhibit 2 shows the proposed redundant network. Which technology would provide faster convergence over the newly introduced layer 2 domains?
Correct Answer: A
Question 9 of 253
A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A customer wants to connect one site with one box redundant to the Resilient Ethernet Protocol ring at two different service provider locations. How can this be done without producing any Layer 2 loops within the network design?
Correct Answer: D
Question 10 of 253
Refer to the exhibit. Your company designed a network to allow server VLANs in a data center to span all access switches. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. In which three ways should the design of the STP domain be optimized for server and application performance? (Choose three.)
Correct Answer: B, D, F
