Designing Cisco Network Service Architectures
Question No: 1
Which two technologies that can be used to connect data centers over an IP network and provide
layer 2 LAN extension?
Question No: 2
Refer to the exhibit.
Which option should be the default gateway for the PC1 that is shown?
Question No: 3
The requirement for high availability within the Data Center network may cause the designer to consider which one of the following solutions?
Construct a hierarchical network design using EtherChannel between a server and two VDCs from the same physical switch
Utilize Cisco NSF with SSO to provide intrachassis SSO at Layers 2 to 4
Define the Data Center as an OSPF NSSA area, advertising a default route into the DC and summarizing the routes out of the NSSA to the Campus Core
Implement network services for the Data Center as a separate services layer using an active/active model that is more predictable in failure conditions
Question No: 4
In a base e-Commerce module design, which routing statement is correct?
Routing is mostly static.
Hardcoded IP addresses are used to support failover.
Inbound servers use the CSM or ACE as the default gateway.
VLANs between the access layer switches are used for FHRP protocols.
Answer: A Explanation:
quot;Base Design Routing Logic Routing in this e-commerce module design is mostly static, using VIP addresses to support failover.quot;
Question No: 5
Two company want to merge their OSPF networks , but they run different OSPF domains , Which is option must be created to accomplished this requirement?
OSPF virtual link to bridge the backbone areas of the two company together
Redistribute routes between domains
Question No: 6
Which mechanism is enabled by default in the OTV technology to conserve bandwidth?
Automatic unicast flooding is suppressed over the OTV link.
BPDUs are allowed to traverse the OTV link.
Control plane traffic is prevented from traversing the OTV link.
Data plane traffic is prevented from traversing the OTV link.
Question No: 7
ASA firewall cause outage….maintaining QOS in architecture ……(or)Cisco ASA in active
/active mode, how to pass almost like stateful info across to the other member?
Answer: D Explanation:
ASR = Asymmetric routing
Question No: 8
Which option does the FabricPath technology use to create loop-free Layer 2 networks?
Answer: C Explanation:
Well, the dump said quot;TTLquot; and I think that#39;s not entirely true. TTL ends up a looping packet but the loop can still be there. Fabric path uses IS-IS and the concept of quot;switch-idsquot; which could refer to quot;fabric tagsquot;…
There are also the FTag (Forwarding Tag) which specifies which path the packet traverses…
Not very clear.
If the Q was something like: quot;Which option does the FabricPath technology use to mitigate Layer 2loops?quot;
I would have answered TTL.
Question No: 9
You are assigned the network of 192.168.1.0/24. You want to split the network into four subnets that are all the same size. Which three statements about the first subnet that you create are true? (Choose three.)
The subnet mask is 255.255.255.192
The last host IP address is 192.168.164
The subnet mask is 255.255.255.224
The subnet has up to 64 hosts
The last host IP address is 192.168.1.62
The subnet has up to 62 hosts
Question No: 10
What are two characteristics of Server Load Balancing router mode? (Choose two.)
The design supports multiple server subnets.
An end-user sees the IP address of the real server.
SLB routes between the outside and inside subnets.
The source or destination MAC address is rewritten, but the IP addresses left alone.
SLB acts as a quot;bump in the wirequot; between servers and upstream firewall or Layer 3 devices.
