What network technology provides Layer 2 high availability between the access and distribution layers?
On which two types of links should routing protocol peerings be established according to best practice? (Choose two.)
A. distribution links
B. end user links
C. transit links
D. core links
An HSRP design requirement states that preemption must be enabled for the active switch, which is a Cisco 4507R. Assume a boot time of 300 seconds.
Which setting of the preemption delay timer minimizes the loss of traffic?
A. 50 seconds
B. 100 seconds
C. 150 seconds
D. 200 seconds
The recommended best practice is to measure the system boot time, and set the HSRP preempt delay statement to 50 percent greater than this value. This ensures that the HSRP primary distribution node has established full connectivity to all parts of the network before HSRP preemption is allowed to occur”-> We can’t choose 450 seconds so we take the higher delay available..
What is the next action taken by the Cisco NAC Appliance after it identifies a vulnerability on a client device?
A. denies the client network resource access
B. repairs the effected devices
C. generates a Syslog message
D. permits the client but limits to guest access
“Cisco NAC Appliance compliance policies reduce the threat of computer viruses, worms, and other malicious code on your network. Cisco NAC Appliance is a powerful tool that enables you to enforce network access requirements, detect security threats and vulnerabilities on clients, and distribute patches, antivirus and antispyware software. It lets you block access or quarantine users who do not comply with your security requirements, thereby stopping viruses and worms at the edge of the network, before they can do harm.”
Refer to the exhibit. A customer requires a web application implementation, but the web server has communication only to the application server and users, and the database server has communication only to the application server. What firewall design is the best fit for this scenario?
A. transparent mode with the servers on the same subnet
B. routed mode with three security zones
C. transparent mode with three security zones
D. routed mode with two security zones
Which route summarization most efficiently reduces perceived network complexity that is composed of subnetworks ranging from 172.16.20.0/24 to 172.16.36.0/24?
What is the recommended subnet between two sites that have a point-to-point connection to conserve IP addresses?
In which OSI layer does IS-IS operate?
A. Layer 1
B. Layer 2
C. Layer 3
D. Layer 4
Which algorithm does IS-IS use to determine the shortest path through a network?
A. Bellman-Ford routing algorithm
B. Johnson’s algorithm
C. Dijkstra’s algorithm
