  A. Always

• Question 394:

  Click the Exhibit button to view the With RIP running, what command would be used to set the default route on Router 2 to 171.68.64.6 (Router 3)?

  

  A. ip default-network 171.68.64.6
  B. ip route 0.0.0.0 255.255.255.255 171.68.64.6

  D. None of the above
  C. ip route 0.0.0.0 0.0.0.0 171.68.64.6

• Question 395:

  Click the Exhibit button to view the Host 1 and Host 2 are on Ethernet LANs in different buildings. A serial line is installed between two Cisco routers using Cisco HDLC serial line encapsulation. Routers A and B are configured to route IP traffic. Host 1 sends a packet to Host 2. What is the destination MAC address of the packet on Host's 1 Ethernet?

  

  A. Host 1
  B. Host2
  C. Router A
  D. RouterB
  E. The broadcast address
  C. Router A

• Question 396:

  What SAN topology has the ability to scale to very large networks?

  A. Switched Fabric
  B. ArbitratedLoop
  C. Point to Multipoint
  D. Loop Channel bypass
  E. Point to Point
  A. Switched Fabric

• Question 397:

  Click the Exhibit button to view the topology.

  

  The diagram shows a campus with a L2 switched backbone. The backbone has a single VLAN (= subnet) with no loops. The links into the backbone are routed interfaces, not VLAN trunks. Switch X is the STP root of the core VLAN and switch Y is the standby root. The connection between X and Y is an EtherChannel. The network architect wants to add more redundancy by connecting the L3 switches in the distribution layer to both X and Y. What best describes that plan?

  A. It is a sound idea because it increases bandwidth and redundancy.
  B. It is not sound financially because the extra links will be blocking.
  C. It will cause loops that STP cannot resolve.
  D. It is impossible because routers cannot have two interfaces on the same subnet.
  E. It is a sound idea because packets take a single L2 hop across the backbone.
  D. It is impossible because routers cannot have two interfaces on the same subnet.

• Question 398:

  Within OSPF, what functionality best defines the use of a 'stub' area?

  A. It appears only on remote areas to provide connectivity to the OSPF backbone.
  B. It is used to inject the default route for OSPF.
  C. It uses the no-summary keyword to explicitly block external routes, defines the non-transit area, and uses the default route to reach external networks.
  D. It is a non-transit area that does not allow flooding of external networks and uses the default route to reach external networks.
  D. It is a non-transit area that does not allow flooding of external networks and uses the default route to reach external networks.

• Question 399:

  What significant value to VSANs contribute?

  A. VSANs are a logical segmentation of a physical switch into logical fabrics that allow customers to consolidate SAN islands.
  B. VSANs are physical segmentations in a logical switch fabric that allow customers to create separate SAN islands.
  C. VSANs are a logical segmentation of a physical fabric into Arbitrated loop topologies.
  D. VSANs are physical boundaries between blades on the MDS.
  A. VSANs are a logical segmentation of a physical switch into logical fabrics that allow customers to consolidate SAN islands.
