Cisco 350-001 Exam Question & Answer

You have 2 Cisco routers that are configured to run BGP and have been connected to a firewall, one on the LAN-inside interface and one on the Internet-outside interface. The Border Gateway Protocol has been configured so the 2 Cisco routers become peers. What first test can you start up, to see if BGP will work correctly across that firewall?

A. Try to open a TELNET session from the router connected to the LAN side of the firewall to the router connected to the Internet side of the firewall. If you can start a telnet session, BGP will also work, since telnet and BGP both use TCP to transport data.

B. Ping from the router that is connected to the LAN interface of the firewall to the router connected to the Internet interface of the firewall. If Ping works between them, BGP should work, since BGP uses IP to transport packets.

C. There is no method to make the Border Gateway Protocol work across a firewall without using a special configuration, consequently there is no test that will show you if Border Gateway Protocol will work or not. You must try to start a peering session and see what happens.

D. There is no method to make Border Gateway Protocol work when using a firewall.

Cisco 350-020 Exam Question & Answer

The OSPF protocol is configured on a Frame Relay interface providing point-to-multipoint connections. All the remote neighbors can reach the central site, but there are routing failures between each of the remote sites. The central router holds all the routes for all the remote sites. Based on this info, what can be identified as the main possible problem?

A. An over-subscribed Frame Relay switch will cause some packet loss.
B. OSPF Authentication has a problem.
C. Incorrect selection of the Designated Router.
D. Incorrect DLCI allocated on a point-to-point sub-interface.

Answer: C

Cisco 350-020 Exam Question & Answer

A Cisco router redistributes routing updates from OSPF to RIP. What materials the network administrator needs to be aware of?

A. Split Horizon, Poison Reverse, Holddown.
B. Slow convergence, limited hop-count metric, lack of network mask information, periodic broadcasts.
C. None, OSPF is a link-state routing protocol and this fact overcomes issues found in RIP.
D. Difference in metrics, subnet mask allocation and addressing, routing protocol summarization.

Answer: D

B. The penalty is exponentially decayed according to factors, such ashalF, lifE, time.
C. The history of unstable routes is forwarded back to the sender to control future updates.

Answer: B

Cisco 350-026 Exam Question & Answer

The EIGRP protocol, in Cisco routers, applies the principle of Feasible Successor (FS) in determining a new path to a lost route.
What declaration about the Feasible Successor (FS) is true?

A. EIGRP protocol, proposes a central router as the Feasible Successor for all missing routes during configuration.
B. Information is kept for the Feasible Successor as part of the Link-State Routing updates send for EIGRP.
C. EIGRP estimates the Feasible Successor from each neighbor and for each network after an exchange of database information during the normal update procedure. It uses this material for path selection when a route is gone.
D. When EIGRP is informed that a route is missing, it will continuously send requests to each neighbor for ways to reach the missing route. The neighbor that provides the best route will be nominated as the Feasible Successor.

Answer: C

Cisco 350-026 Exam Question & Answer

Some Cisco routers can use the OSPF protocol. What phrase better describes the use of a 'stub' area?

A. This area injects the default route for OSPF protocol.
B. It is configured only on remote areas and provides connectivity to the OSPF backbone.
C. It is a non-transit area that does not permit flooding of external networks and uses the default route to reach external networks.
D. It uses the no-summary keyword for blocking external routes. Also describes the non-transit area and uses the default route to reach external networks.

Answer: C

Cisco 350-026 Exam Question & Answer

B. The client sends a list of supported cipher suites, and then the server selects the cipher suite it wants to use.
C. The client and the server take turns in sending proposals back and forth, till they agree on a cipher suite.
D. The server sends the cipher suite it wants to use; the client must support all cipher suites.
E. The client sends the cipher suite it wants to use; the server must support all cipher suites.
