In search of a system capable of hosting, monitoring compiling and testing code in an automated way, what can be recommended to the organization?
- A . Jenkins
- B . Ansible
- C . Perl
- D . Chef
Company XYZ is running BGP as their routing protocol. An external design consultant recommends that TCP path MTU discovery be enabled.
Which effect will this have on the network?
- A . It will enhance the performance of TCP-based applications.
- B . It will increase the convergence time.
- C . It will improve the convergence time.
- D . It will create a loop free path.
Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the network.
Which layer accomplishes this design requirement?
- A . fault management
- B . accounting management
- C . performance management
- D . security management
Which two characteristics apply to firewall transparent mode operations in a firewall solution design? (Choose two.)
- A . Changes in the existing IP addressing and subnets are required
- B . The firewall can participate actively on spanning tree.
- C . Multicast traffic can traverse the firewall.
- D . OSPF adjacencies can be established through the firewall
- E . The firewall acts like a router hop in the network.
Refer to the exhibit.
A customer runs OSPF with Area 5 between its aggregation router and an internal router When a network change occurs in the backbone. Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5 You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B does not support the stub area.
How can you accomplish this task*?
- A . Increase the bandwidth on the connection between Router A and Router B
- B . Implement LSA filtering on the AB, allowing summary routes and preventing more specific routes into Area 5
- C . Create a virtual link to Area 0 from Router B to the ABR
- D . Turn on LSA throttling on all devices in Area 5
- E . Set Area 5 to stubby at the ABR anyway
Which two factors must be considered for high availability in campus LAN designs to mitigate concerns about unavailability of network resources? (Choose two.)
- A . device resiliency
- B . device type
- C . network type
- D . network resiliency
- E . network size
Which optimal use of interface dampening on a fast convergence network design is true?
- A . When occasional flaps of long duration occur
- B . when numerous adjacent flaps of very short duration occur
- C . when the router hardware it slower than the carrier delay down detection
- D . when the switch hardware is faster than the debounce timer down detection
A BGP route reflector in the network is taking longer than expected to coverage during large network changes. Troubleshooting shows that the router cannot handle all the TCP acknowledgements during route updates.
Which action can be performed to tune the device performance?
- A . Increase the size of the hold queue.
- B . Increase the size of the large buffers.
- C . Decrease the size of the small buffers.
- D . Increase the keepalive timers for each BGP neighbor.
A healthcare customer requested that SNMP traps must be sent over the MPLS Layer 3 VPN service.
Which protocol must be enabled?
- A . SNMPv3
- B . Syslog
- C . Syslog TLS
- D . SNMPv2
- E . SSH
Refer to the exhibit.
This network is running OSPF as the routing protocol. The internal networks are being advertised in OSPF London and Rome are using the direct link to reach each other although the transfer rates are better via Barcelona.
Which OSPF design change allows OSPF to calculate the proper costs?
- A . Change the OSPF reference bandwidth to accommodate faster links.
- B . Filter the routes on the link between London and Rome
- C . Change the interface bandwidth on all the links.
- D . Implement OSPF summarisation to fix the issue
